Re: [Flexradio] Flex has already announced an updated version of PowerSDR to be released

[Mike King - KM0T]

Snip...

Fortunately Flex has made the primary source code available, and we are
seeing developers add functions or fix minor glitches. Thank you all who
have the specialized skills to do this, and are willing to share.

Snip...

I know there are some versions of PowerSDR out there that were redone for
other hardware platforms and uses

Are you saying there are other versions for the Flex-5000 not done by Flex
Radio?   Can you point out where these versions of PowerSDR are available
for the Flex-5000?  I am not aware of these  

Thanks

This is a topic that will typically stir considerable debate
on email reflectors. Some reflectors default to only
responding to the original sender like this one does
currently, and others default to replying to the entire list.

I would favor leaving the behavior of this list the way it is
now, the other option inevitably causes plenty of
embarrassment when something private gets sent to everybody,
then all the "oops I didn't mean to do that" emails that
always follow. This happens *very* frequently on lists
configured to "reply to all" by default.

If someone is responding and they want to make it go to the
entire list they will need to specifically choose to do so. I
feel this is the better and safer overall configuration based
my observation of numerous other lists.

Hi all, I just received my Delta 44 from Flex-radio.  No CD was included for

I think I saw something regarding using external PTT (sequencer, foot sw.)
recently (maybe from Bob) in new versions.  Just tried 1.3.10 and my 
external
sequencer does not key SDR to Tx via the 15 pin connector in V.1.3.10. 
Keying
the sequencer (to operate antenna relays) and then clicking MOX puts the

into Tx.

[Flexradio] Problem with SDR in MOX

[Mike King - KM0T]

Hi all, I was playing around tonight with the SDR-1000 and was working on
some interfacing with the X2 connector for PTT and such.

Somehow the radio got in a state of perpetual MOXyou hit the MOX button
and it just stays there in transmit.  It briefly goes off, but then
automatically goes right back into MOX mode.

So I disconnected all the power from the SDR and rebooted everything, still
does it.

So I turned everything off, cut the power and took the connector off the
X2...disconnected the mic, etc.

Just started the software and when I hit the standby button, sure enough the
software itself goes into transmit as the MOX button is then highlighted.
Even with the SDR power off.

I figured it might have had something messed up with the database, so I
started up an earlier version and it did it there too.  I went back thru all
the versions back to 1.2 and no luck.  They all did the same thing.

So, anyone have any ideas?...seems strange that even with everything off the
software just goes to mox.  I rebooted the computer a few times too thinking
it could be windows for some reason, no difference then either.

Thanks and 73

Is your rig actually being keyed up?



Absolutely, I had the rig on a dummy load for testing purposes.  Its the 1 
watter fyi.


Check your printer port.  I got the symptoms you did by having the wrong 
printer port address.  As far as I can tell, the printer address is also 
not altered by importing a database.


Not at the rig right now, but I will check the address.  I did not import 
any database and this was a completly fine working system, why would 
anything change the printer port address?


Im still scratchin my head on this one.  I have not disconnected the 
parrellel cable yet from the SDR-1000, guess I will do that next.  However 
with no power on the radio hardware, I did not think that would be an issue.

If that is true, the radio isn't really being keyed -- the console thinks

[Flexradio] Parallel Port Address

[Mike King - KM0T]

Hi all, Im pretty sure I blew my Parallell port on my Motherboard, so I 
added a PCI to Parallel card today to the system.  However, the card sets 
and grabs address that are not legacy vintage, i.e. DF38-DF3F, which is not 
an address availble in the SDR software setup menu.


Because of this I cant get the SDR-1000 console to respond to the parallel 
port, and XP wont let me change the address range.


Is there way to add choices for the I/O address range within the SDR-1000 
console setup?

To all, got it running and it seems to be working ok.  Then the kids started 
screaming so I could not really put it through its paces :)  It seems to be 
good though!





Can you go into the BIOS and disable the mobo parallel port?


Jim, sure can, however the new cards wont grab those address.


Mike,
One thing to watch out for is that in the past, the console would never 
maintain my non standard
parallel port setting when upgrading to a new version and loading in a 
previous database - it would
instead use the default parallel port address. Eric had added my non 
standard address (BC00)
to the drop down  list and then it worked, so I haven't had to worry about 
it - but since yours isn't

on the list you will probably see this problem in the future.

[Flexradio] Delta 44 Questions

[Mike King - KM0T]

Hi all, I just upgraded to the Delta 44 as I had been using the Audigy 2 ZS 
up till now.


One thing I cant seem to find is how one controls the line in gain, as it is 
un-highlighted set on 20.  I believe I read that these are defaulted, non 
changable values unless you select "unsupported card"  Is this right?  Sems 
to me this is what I had the audigy card set at as well.


Also, I thought I would have to use the mic in gain control to get the 
output ramped up since Im not using a seperate pre-amp or second sound card. 
The value of the mic gain in the menu is "6" and the front panel was 50. 
Just as it was with the Audigy 2 ZS card.  These values drive the audio just 
fineso I was wondering is this was correct as I thought guys had to have 
the gain up to 40 or 50 to make it work.


More questions probably to follow.  Thanks much.

[Flexradio] CW Sidetone Monitor

[Mike King - KM0T]

Hi everyone.  I recently upgraded to the Delta 44 sound card and things seem 
to be going well.


I decided to check the monitor function and it works great!  The latency for 
CW is really good and I would certainly consider using it, except it is way 
too loud.


Is there a way that I'm not seeing to adjust the sidetone CW monitor, so it 
does not mess up the volume of the signals being heard in RX mode?


Thanks!

PS - I can now have powered speakers and headphones connected to the Delta

I was on 20m ssb a few minutes ago with the SDR-1000 (of course), and
had just signed with a mobile station in Oklahoma, when I heard a very
weak station calling me.

I was on 14.162 MHz, with some S9++ signals nearby at 14.168 MHz, and an
S9+ signal just below me at 14.159 MHz, but by narrowing down the filter
to 2.6K and shifting the filter a bit I was able to pull the signal
(about S3) through the QRM. The op was Joe, N4TSU, and he said that he
was in New Orleans and asked me if I could call his brother William to
let him know that he was okay. I called the number, and although his
brother was not home, his brother's wife answered the phone. I explained
that I'm a ham radio operator in Ohio and had just spoken with Joe, and
he wanted me to let them know that he was fine. Needless to say, she was
elated to hear the good news, and said that her husband had been calling
all day long from work, to see if there was any word about his brother.

I've always hoped that one day I'd be able to help out in a situation
like this, and was thrilled to be able to do so. Considering the band
conditions at the time, I am quite certain that had I not been using the
SDR-1000, I wouldn't have been able to copy the phone number and other
information.  It made my day.

Re: [Flexradio] PowerSDR 1.4.5 beta - 2M Tx

[Mike King - KM0T]

Let me re-iterate Eric's comments.

The new xvert form will allow you to setup anything one might possibly want. 
I personally use SSB Electronics and DB6NT transverters for my microwave 
stuff, and they are all 144 MHz driven.  I use the SDR-1000 at 28 MHz to 
drive the 144 MHz transverter.  The 144 MHz transverter in turn drives all 
the rest of the microwave transverters from 902 to 24 GHz.  The xvert menu 
allows me now to show all the real frequencys on all the transverters from 
the Power SDR console.


Everything is controlled via the UCB.  Everything works good.  Made 157 QSOs 
on 10 GHz last weekend with the SDR-1000 for the 2nd weekend of the 10 GHz 
contest.  Worked like a champ.


I dont use the DEMI optionI use the BNC output from my 1 watt SDR-1000. 
On the VHF+ menu - One of my band buttons I have programmed as "144 IF" - I 
set that for 144.000 to 146.000.  The rest of the band buttons IF offsets 
are set as an example - 10368 MHz - 28 Mhz to give the offset as 10340. 
Then I set the band limits to 10368 to 10370.

Good.  This is exactly what the new XVTR form has been built to handle.
My previous email can be read as follows: "If you have a DEMI 2m XVTR
purchased from us, you don't HAVE to use the new XVTR form (though some
might want to)."  For those of you with different designs with different
IFs and that cover different bands, this form is EXACTLY what you want.
It enables you to completely customize the behavior of the console
including direct frequency readout to match your hardware setup.

I am and have been using the 2M transverter I designed several years

not
the DEMI unit.  It is highly unlikely that serious VHF/UHF/uW weak

operators will ALL purchase DEMI units over their own designs and

[Flexradio] Preview 2 Observations

[Mike King - KM0T]

Hi all, its working here real good.

I worked from a previous database import.

I hear some intermitiant buzzes when moving around and clicking on things, 
it does not do this all the time.


Something funky is going on with the power level controls...(1 watt version 
here)


When I set the RF levels on SSB or CW to 100, they stay there unless I go to 
the FM mode.  When I go to FM mode, it starts out at "6".  I ramp that up to 
the max of "25".  When I switch back to CW or SSB, then the power level was 
changed to "24".  If I switch back to FM, then that power level is now at 
"6" again.


Huge deals

The CW side tone adjustment is awesome!  Thanks Guys!

The X2 Sequenced output now works with my UCB connected.  It does not change 
the state of the UCB during TX when using this feature.  Eric, what did you 
do???


+/- freq offset in the xvert menu is done...great!

I just saw Beppe say the recorder crashes it, I have not tested that.

Re: [Flexradio] Frequency calibration etc

[Mike King - KM0T]

I too have been using an external 10 MHz source on my SDR.

First I used a Rubidium source off of ebay, never noticed anything different 
from the internal crystal other than no drift.  (rock solid)


Note that I have only used it on 902 thru 24 GHz - where the SDR is the 28 
MHz IF.


I recently switched the 10 MHz source to the HP Z3801 GPS receiver.  I A/B 
switched the Rubidium and Z3801A back and forth and could tell no difference 
in the audio.  However when I used the waterfall display while doing the 
switching, the Rubidium source show a bit of light white noise on the screen 
(where I adjusted it) as the waterfall was moving (it was very slight).  The 
10 MHz Z3801A source seemed to eliminate this.


I am not experiencing anything drastic that would indicate the improper 
reception or weak signals covered up while using these 10 MHz sources, but I 
have no way to measure phase noise, just a gut feel for how my system is 
operating on the UHF/SHF bands.

[Flexradio] SDR-1000 kicks butt again on 24 GHz

[Mike King - KM0T]

Hi all,

USING THE SDR-1000 -

I made a 24 GHz snow scatter QSO today for grid number 13, 175 miles - about
282 km.  Jon - W0ZQ was out portable up in Minneapolis.  All the details are
under the current news section on the main page at www.km0t.com

For those of you that may not know, grids are what we strive for in weak 
signal VHF/UHF/SHF...there are a dozen or so in the US with 5 grids.  Two of 
us (myself included) with 10 grids on the band.  No one with 15, thats what 
were trying to do.  This is extreamly difficult given the propagation 
characteristics on 24 GHz and the terrain involved.  In fact, I think it can 
only be done in the midwest, or the Texas area, as there are terrain 
obstacles on the coasts that get in the way.  So, we are praying for more 
bad weather here for going after the next two grids!


There is a nice screen shot of the SDR-1000 showing the signal.

73 and let the snow blow on!  It was very exciting stuff!

[Flexradio] What a way to end 2005 - 24 GHz News

[Mike King - KM0T]

Its been a good year here at KM0T - First off I need to say thanks to all 
the guys that have helped me out!  Without the help, all this would not have 
happened.


I worked 2 more grids on 24 GHz today, to give a total of 15...now its time 
to send off for the endorsement!


Jon, W0ZQ was good enough to go out and brave the 30 degree temps (I know, 
not too cold) but still after the recent storm up in Minnesota with snow all 
over the place, that was a big favor.


I noticed some precip showing on radar around noon today, and watched it for 
a bit as it was moving in a slightly SE path, moving into a potential center 
scattering point for EN25 and EN35.  I got ahold of Jon and we watched it 
for a bit before he headed out.


Jon got to EN25 and fired up the 10 GHz liasion, good signals...I found Jon 
with very little effort, albeit weaker..but what I would call a 56 to 57 
here.  We did not mess around and he headed out for EN35, hoping the precip 
would hold.  No problem there either, but weaker signals.  The storm was in 
the process of breaking up.


Details on path distances and pictures of storms via the rainscatter 
program, as well as an SDR screen shot is on the main page of my website. 
www.km0t.com


The distance was about the same as what we did earlier in December.  Thanks 
again the Andy - K0SM for such a great software tool!  "Rainscatter!" rocks!


It appears that when dewpoints are in the 30s, this distance would be very 
repeatable...if there is some precip near the scatter point.  Im pretty sure 
its snow scatter, as the signal was slightly distorted, but not as bad as 
last time on 12-11-05 when we worked EN34.  (I believe that the storm was a 
slow mover.  No doppler was experienced.)  However, on that day of 12-11-05, 
Jon went to the same spot he went today, and no signals were heard on 24 GHz 
as the storm had broken up by the time he got there back then.  And the dew 
points and temps were about the same back then.  (10 GHz was way down as 
well at that spot when the storm broke up)


We are pretty pumped up for going for more distance nowas the 20 grid 
mark will be a long time in coming Im afraid, pretty hard to coordiante 
trips to the outlying grids with storms, sleet, snow in the right spot, but 
we shall see.  But it sure dont mean I wont try :)


The SDR-1000 bandscope was instrumental once again in quickly finding the 
signals, as Jon had done some mods to the 24 GHz dish he was using and the 
freq I expected to find him on was not working out.  Some quick tuning and I 
saw him 25 Khz or so up from where I expected, but the SDR made it easy! 
"Oh- I see you!" is getting to be a pretty standard statement when using the 
SDR-1000!


Thanks again Jon-W0ZQ for going out again.

Re: [Flexradio] Repost - Multiple SDRS one CPU

[Mike King - KM0T]

Hey guys, very intresting indeed.  But if you used for instance an 
additional parrallel port card.  Could you not just set the port addresses 
in each instance of PowerSDR...no USB confusion.  That would take care of 
the control.  How would one install say two Delta 44 cards and make them 
look at the appropriate instance in software?  Would there be a way to "hard 
set" this in software, or would it be a matter of the first instance of 
PowerSDR you booted went to Delta 44 #1...second boot of PowerSDR would go 
to Delta 44 #2.


It would seem that there would have to be some hardware indentifier in the 
card, that when when you run the setup menu and select Delta 44, it should 
ask "which one"  Then it would seem that alls theres too it?


I would think you would want a way to seperate the databases for both 
instances of PowerSDR?  Say one needs two SDRs...connected to one machine 
and running the upcoming 1.6 release.  If you run both, does it not use the 
same database, cause all your doing is running the same program again.  If 
for instance I want one SDR to be an HF machince and the other SDR one 
dedicated for using the UCB and my transverter interface, I would think you 
need a seperate database to keep all the goofy setting seperate.  Or would 
one simply install PowerSDR a 2nd time and choose a seperate directory? 
That way it would have a seperate database?


Boy, this would be great for real estate space.  A Pent 4 3.4 GHz with a gig 
of ram should have no problems...especially a HyperThread chip, PowerSDR on 
each thread?


Hope you can look into this Eric!

Re: [Flexradio] Repost - Multiple SDRS one CPU

[Mike King - KM0T]

Eric and all, thanks for the comments.  I think as discussed below, if your 
ultimate setup is using two Delta44 cards...(as I would like to have) the 
control panel handling two cards...I remember seeing that it could handle 4 
devices.  I guess one would not have to install the software again for the 
Delta 44!



How would one install say two Delta 44 cards and make them
look at the appropriate instance in software?


[Eric] This is a good question.  Apparently, the Delta Control Panel is
setup to support up to 4 physical devices (as shown in the H/W Installed
groupbox on the right side of the panel).  I'm not sure how they handle
multiple cards, but I'm sure it could be done predictably (i.e. you
shouldn't have to worry about starting one instance before the other).


For those using all the other great software hooks, like VAC and such, this 
may complicate things, but I have not dived into all that...(not yet anyway 
:)


If anyone installs two D44 cards and has two SDRs going, please post the 
results.  I dont have a spare card right now to try.

PS - Duane, have you benched the AMD processor with PowerSDR against an 
Intel P4 3.4 650 processor or similar?  Is your AMD the dual core unit?  I 
would think even the new Intel dual core processors would be excellent at 
this, as then there are 4 virtual processors.  (Hyperthread X2)

Re: [Flexradio] Repost - Multiple SDRS one CPU

[Mike King - KM0T]

Roger that, its not double, however its "probably good enough"  I do believe 
that the new dual core processors have seperate 2MB cachesso all the 
better.


The P4 I run with the 2MB cache and the refresh of the pan adapter window 
over 30 FPS only makes the unit sit around 15% cpu utilization.  So Im 
guessing these machines could handle it.

HT doesn't necessarily give you twice the throughput.  In many systems, 
it's the memory bandwidth that limits you. I believe that both CPU cores 
share the same Level 1 cache, so if your application is anywhere near 50% 
utilization, HT might not buy you much.  Makes context switches real fast 
though, and allows clever pipelining schemes (speculative execution of 
both branches, for instance).


You can go hit the beowulf archives (http://www.beowulf.org/) for a lot of 
discussion about the value (or not) of HT in highly compute bound 
applications.

Re: [Flexradio] An OCXO for the SDR-1000

[Mike King - KM0T]

Alan, excellent report on the OCXO...it all looks great.  Now per Jim's 
comment about going higher in freq is an advantage due to phase noise being 
multiplied inside the DDS, can anyone compare this 40 MHz unit and its phase 
noise  - multiplier of 5...to a GPS HP-Z3801A at 10 MHz with the multiplier 
of 20?


I understand the phase noise issue, but have no equipment that can test / 
compare.  Im currently using the HP GPS unit to feed the my SDRs at 10 
MHz...made lots of weak signal microwave QSOs with them (and the rubidium I 
had previously for that matter)  I wonder how much Im possibly missing out 
on.  One Hertz max error after calibrating with less phase noise and the 
reduced complexity / connections to the HP Z3801A is very inviting.


Alan, what dbm did you pump into the crystal slot?  I dont recall seeing any 
data on that for what the 40 Mhz unit had for output.

My OCXO equipped   SDR-1000 is now within  0.05Hz of 15mHz WWV and it
doesn't deviate more than  0.5Hz under varying temperature due to long
transmissions!  I no longer need to 'tweek' the VFO to compensate for my
rig drifting, what a relief!  For the 1st time I can rely on the frequency
readout of my SDR-1000 ­ down to ONE HERTZ.   That $150 OCXO has made the
SDR as stable as  the  $1  Icom IC-7800.





There is an advantage in going higher in frequency, because the noise gets
multiplied up inside the DDS.

Re: [Flexradio] intermittant power glitch

[Mike King - KM0T]

Well, I have sort of a variation of the power glitch described.  I though it 
was just me or my hardware, but perhaps it is related to a version of 
software.  For me it has not always done it, but at for version 12 and 
perhaps one before.  This I would need to test as it has crept in over the 
last few months..but I did not give it much thought as I figured I had 
something messed up in the SDR hardware.


What happens is that when all is booted up and everything is working fine. 
If I leave the room and come back (or just do something else for a bit), for 
some undetermined amount of time, the Power SDR is just monitoring.  When I 
go and PTT, the software does not go into PTT...I get a "noise line" on the 
pan adapter...and no modulation shown.  A quick cycle of the standby switch 
fixes this and when I PTT then, it transmits.  This is in CW or SSB.  It 
does this sometimes, never, and once in while...in other words I cant 
predict when it will happen.


So, mine does not happen on going back to RX, but only going to TX.  Anyone 
else have this specifically?  I am still looking into my PTT hardware scheme 
to see if there is something there.  I have wondered too if the PTT input 
chip on the X2 might somehow be damaged.


What would be good is if I had specific benchmark for test voltages and a 
procedure on measurements on the X2 pins to be sure the hardware was working 
properly.  Then I could say its "hardware" or "software".


I monitor all the time in pan adapter mode with the AVG turned on.  Note 
that sometimes the S-meter gets stucka quick recycle of that fixes 
that...but I don't believe it is related.  I am using the parallel cable for 
attachment to the CPU.  Typical use is the SDR-1K with the UCB and VHF+ 
menu, so I have alot of variables that might contribute.

Version 12 glitch

On occasion, regardless of the voice mode being transmitted, when i go
back to receive there is no received signal (only noise on the
panadapter),
then when i go to transmit again there is no rf output.

This occurs on all priority levels.

If I set the sdr  software to standby then back to on it recovers.

[Flexradio] Parallel Port Cards

[Mike King - KM0T]

Hi, some time ago I saw someone provide a link to "high quality" PCI 
parallel port cards...I'm assuming there may be better ones than others. 
Looking for feedback on brands - manufacturers of these cards that are 
perhaps above the general $8 card you get on eBay or various computer

Re: [Flexradio] Sampling rates greater than 48K question

[Mike King - KM0T]

My 2 cents here..

I too heard that this required a capacitor change in regards to maintaining 
the quality of the receiver once the software is opened up to show more 
bandwidth.  It is a hardware / software solution.  Where the software is 
ready to do its thing, but the hardware needs the mod.


What is needed on the hardware, if one wants the best in all panadapter 
resolutions is a relay(s) to switch a capacitor network.  Should be an easy 
add.  Software can flag the correct setting to the relays to give the proper 
cap network with the bandwidth setting.


However, this is not ready to go, but if one is willing to compromise the 
dynamic range (such as I would) to see more bandwidth, so be it...in the 
microwave world (or 2 meters for sure), we would love to see more, but we 
rarely have 30 over pileup signals on 10 GHz right next to that weak guy Im 
trying to dig out.  (although that would be awesome)


I think if one could allow the panadapter width to be "let loose" so to 
speak, one with a variable width slider to the users choosing, great.  Just 
be prepared that the wider setting would not meet the current 
specifications.  Guys out there smarter than me could figure out this 
capacitor thingy :)

I don't think so.  You see, with the caps, you are setting the bandwidth
of the hardware receiver.  The caps set the limit.  You could use less
than this (change caps for 80kHz, use 48kHz sampling rate), and it would
work fine.  But you will not have the same dynamic range as you did
before you changed the caps.  Hopefully I'm explaining this correctly as
I am really stepping outside of the software box here.  ;)

Is it also true that if the caps are changed to support 96K, that you
can use 48K if you want to get better dynamic range without a hardware

Re: [Flexradio] Ameritron amp with SDR-1000

[Mike King - KM0T]

Bob - Well, here is my 2 cents...being fairly green on HF, I broke down and 
got the SDR-1K with the HF amp.  So I then upped the ante with an Ameritron 
Solid State ALS-500RM.   With 10 watts drive, it easily get the ALS-500 to 
300+ watts.


Anyway, very simple interface.

On the X2, ground pin 11 to 15 for PTT of the SDR.  I just use a handheld 
PTT switch for this.


I then I take pin 7 - Sequenced PTT out of the SDR-1K to a small potted 12V 
coil relay, where the X2-7 is connected to the ground side, and just 12V off 
of the local supply to the + side of the relay.  I use a diode across the 
relay for tranisients.


I use the dry contacts on the relay to provide a contact closure for the 
"Relay" input on the amp.  All this is doing is bringing the amp's relay 
circuit hot side to ground.  Works like a champ.  I enable the sequenced PTT 
output in the setup menu and set the delay for 50 ms.


Isolated the SDR-1K from the rest of the world, no worries now.

Had great reports from everyone except the SSB Hi-Fi guys on 20M, but its 
pretty hard to satisfy them.  Im working on that...Oh well.  Really enjoying 
the SDR-1K on HF!


I would think a similar interface for the tube amps might be about the same? 
Never had a tube amp, so I might be completely off here.

Re: [Flexradio] Interesting artifact

[Mike King - KM0T]

I too see this and it whistles as it passes through the selected filter 
bandwidth.  In fact I see this in all my SDRs (4) as I use them for IF 
radios for VHF+.  The artifact shows up on fairly strong on 28 MHz and 
travels up and down the band in a random fashion.  Like Tim indicated, they 
do not decrease in intensity, but seem to stabilze, but start moving around 
when using the radio.  These are not covered up by band noise for me except 
when the gain from my trasverters pushes the pan adapter base level up a 
bit.  I have often wondered what they are and if there is anything I can do 
to get rid of them.  I am assuming it is being generated inside the SDR-1000 
radio.  The hardware versions of my SDRs vary over the last 2+ years, with 
the latest one about 6 months old.

When I got my first SDR those few years back, I really dont remember seeing 
this, but now it is, might be an oversight however.  However I was using the 
Turtle beach and Soundblaster cards.  I now use all Delta 44s, I wonder if 
that might be a clue?

Any more clues to eliminate would be appreciated!

[Flexradio] KM0T June VHF and SDR-1000 Operation Notes 6M

[Mike King - KM0T]

Well, I missed you all up there in EN34 land during the contestfor a 
good reason

I was not able to get the tower up with the 50 MHz thru 3456 MHz bands, the 
winds just were to strong to risk it

So, I took the kids to the Sioux City Hamfest on Saturday Morning.  On the 
way back, the 6M band was way open and I was working guys left and right 
from the mobile, just a typical vertical on the truck.

That got me to thinking, so when I got home about noon, I tuned up my 
StepperIR HF vertical to the 3/4 wavelenght mode on 6M.  It had an excellent 
match and I hooked my 6M system into it.

This was the first time I was using my SDR-1000 at 28 MHz IF driving a 
transverter on 6M which was to get broke in during the contest.  Well when I 
turned it on, the band was full of signals.  A few checks and getting 
Roverlog on the laptop was all I needed.

With the vertical, I did 400+ QSOs and 117 grids the first day, most in the 
first 3 to 4 hours.  The band was open pretty much all day up till about 
10:30 or 11:00 PM, so I hit the sack.  When it was very hot and heavy, I was 
able to run a frequency for over an hour and get mutiple call backs to 
CQing.  When things died down a bit, CQs would go unanswered, so I would 
hunt and pounce.  The band was full many times up to 50.300 here.

It was intresting using a vertical during the contest, kind of gave a new 
prespective.  I would hear a grid and begin to think about rotating the 
antenna to that heading, but I would have to stop myself :)  Hearing signals 
and getting callbacks from east, west and south was pretty neat.

The SDR-1000 never burped the whole time  (using official realease 1.6), and 
I hit it pretty hard with actually having QSO rate the first few hours of 
the contest, and then for an hour and a half period later in the day. 
Having extreamly strong signals from all parts of the country at the same 
time would have put most rigs to shame, but with the awsome filters and 
using a SSB Electronics LT6S transverter made it a non-issue.  I operated 
alot below 50.200 where the big guns were at and was able to pull the weak 
ones out, even when right next to K1WHS, K8GP, etc.

When it came to hunting and pouncing, the SDR-1000 got an A++.  I could fnd 
/ see these signals pop up, click em and work them before they were gone. 
This made alot of difference when it came to finding some weaker 
multipliers.  I was using the wider bandscope where the width is +/- 20 KHz. 
This came to be extreamly handy and quite easy after a few minutes of 
opeartion.  In addition, when it came to finding a clear freq, that was very 
handy as well.  I could find a few big guns, see a small spot between and 
fit myself in there.  It was intresting to see who had their amps adjusted 
correctly and who had notthere is a wide varience on the big guns on how 
this looked.  Im naming no namesThe guys who had it right were very 
distinct 2 to 2.5 KHz wide signal with almost slope, others were much much 
wider.  Those wider guys I had to stay away from as even the filters wont 
help there :)

Sunday was pretty slow, brief opening to all parts, but few and far between. 
I ended up being around 490 total QSOs and 143 mults or so, cant recall 
exactly.  I heard some outrageouse numbers on how many 6M QSOs were done on 
the first day by some, I will bet I could have doubled mine if my yagi was 
up.  Also, the run to my HF StepperIR vertical is pretty long, LMR-400 - I 
would guess I had a few dB loss there too.  However, it was better than 
nothing and I was able to get on the contest for breaking in the new 6M 
SDR1K setup.

Short skip on 6M was in bigtime most of the day and on Sunday.  I was not 
surprised to hear about the 2M Es...too bad I missed that too.

The vertical is not too good of a local antenna.  Hence no 5, 10 and 24 GHz 
contacts were made...not able to contact anyone in close to do the 
coordination.  (That microwave tower was up...)  The only two locals I 
contacted on 6M was EN41and EN23...both very weak.  I did hear Tim and Pat - 
K9ILT/R one time when they were in EN60, but could not get ahold of them.

For those wondering if the SDR-1000 can be a contest radio, well I dont 
think one can abuse it any more than I did over the weekend.  Works just 
fine and gives alot of advantage!  I for one cant ever fathom going back to 
a dial radio.I only used the mouse wheel and clicking for the tuning. 
Takes a few minutes to get used to it, but after a bit you wont need 
anything else.

Thanks for all the QSOs!

Re: [Flexradio] getting sdr1000 to work 100%

[Mike King - KM0T]

Paul,  I had this in all my SDRs for some reason.  I turned off my Parallel 
port on the motherboard and installed a Parallel port card...seemed to make 
99% of the gliches I have go away.  I used Dells and Gateway machinces here, 
they all do the same thing.  This RX drop out I had been chasing since the 
day I got my first SDR1000.  It only took about 2 years before I switched to 
a port card. :)  I was trying other fixes, suggestions, etc with no 
sucesses.

Good luck!

[Flexradio] 96khz playback issue again

[Mike King - KM0T]

Hi all, seems to me I read here a few weeks ago or longer, a method to 
playback 96 kHz recorded waves on systems that dont support it, i.e. a 
laptop...  Or I might be wrong.

Problem is that I recorded on one of my systems at 96 KHz, and trying to 
playback for a demo on my laptop.   It really doesn't like it :) as it only 
supports 48 KHz.

Its either some workaround method, or getting a Presonus Firebox as the 
soundcard.

Oh, one more thing...was there a change to the PowerSDR database format?  It 
seems that for 1.6.2, my MS Access program wont open it.it complains 
about the file being a non-compatible format and wont open the file.  Any 
help here appreciated.

Thanks all,

[Flexradio] Firebox Info

[Mike King - KM0T]

It looks like there are lots of places to get a Presonus Firebox, some 
cheaper than others, etcand of course eBay.

I am wondering if there are advantages of where to get one, i.e. firmware 
version, what to look out for, etc. since I have seen a number of 
discussions going on here for version and perhaps an update coming from 
Presonus.

Looking for advice.  Thanks!

Re: [Flexradio] Dual Core Optimization

[Mike King - KM0T]

Gentlemen, I purchased one of these back when they were a bit more high 
buck, very solid machine.  I use it for my HF SDR-1000.  However, it is 
SLOWWW compared to an identical configured Dell 8400, which you can get 
cheaper on ebay, etc.  Just food for thought, but I was very blown away on 
how this machine compared with my other machines.

Re: [Flexradio] Straight Key Operation

[Mike King - KM0T]

Hi guys, thanks for getting Barry rolling here.  I was tied up in the UHF 
contest over the weekend, so I was not able to respond...

One other tip (no pun intended)

I happen to use a bencher paddle and outboard hardware keyer, so it is 
essentially a straight key.

When I bumped the paddle, it would put the rig into TXSomething I dont 
like unless Im doing break-in.  It would also do it in SSB mode, not good. 
So I noticed that one of my SDR setups did not do this.  What I came to find 
out was that the ones that did it, were connected TIP/Sleeve..the one that 
did not was connected Ring/Sleeve.

So I switched them all to Ring/Sleeve and no more accidental Transmissions 
when I bump my paddles.

I dont know if this is documented as a feature, would be intresting if 
someone else would verify this, as I was told that there was no way to fix 
it.

[Flexradio] Spurs at KM0T

[Mike King - KM0T]

Well, with the current "spurs" discussion going on, a few have emailed me 
directly to ask how I have been dealing with the spurs...so here goes...

I think as Bob mentioned, the bandscope is our best friend and worst 
enemy...due to the spurswell I guess I have worked with my SDRs enough 
to not give them much thought...although they are there and occasionally 
show up in a passband.

Now I am only commenting on 28 MHz spurs due to the fact that I use the SDR 
for the IF of my VHF - UHF and microwave transverters.  One fellow mentioned 
that he did not see any spurs on my 24 GHz screen shots...well they are 
there, but they are covered up by the gain of my transverter chain.  Where I 
use the SDR at 28 MHz to drive a 144 MHz transverter, then that in turn 
drives the 24 GHz transverter.  Well, the preamp gain of my 24 GHz 
transverter is very high, approx 30 db, so it brings the bandscope level up 
pretty high.  If you look at these screen shots, the noise level on the 
S-meter is approximately at -110dbm without any signal, high enough to cover 
all but the worst spurs.  However where the gain is less, such as on my 5 
and 10 GHz transverters, the spurs are seen, but not too bad.

In the case where I use the SDRs at 28 MHz to drive just 50, 144, 222, 432 
MHz , etc transverters, the gain there is much lower in the overall chain 
and the spurs do show up and do cause an occasional issue, but again the 
benefit of seeing the signals through the spurs far outweighs the spurs 
themselves.  One can "check" and "un-check" spur reduction on the fly to 
move a spur that wont seem to go away if need be, this is one reason to have 
the spur-reduction checkbox on the main screen I think

For me, it is difficult to say that the spurs are on x frequency, as I 
kind of have a different situation...I have found that with multiple SDRs in 
the shack all running at the same time, that the spurs on the SDR I would be 
using to make a contact are dependent on where the other SDRs are tuned.

As and example, when tuned to 144.200 the calling frequency on 2M, this is 
not too much of a problem if the 6M radio is tuned to 50.125 and the UHF SDR 
is tuned to say xxx.100.  But as one move around and the KHz frequencies get 
close to one another, the spurs come and go in the passband for sure.  They 
all interact with one another.

During the UHF contest and I had two SDR-1000 hot, where I was using the 
calling freq say on 222.100 or 432.100 MHz, when tuning the other microwave 
SDR to 10368.100 would cause problems.  I would find myself grabbing the 
other mouse to move the other SDR off of xxx.100 so the spurs were not in 
the passband of the one I was using.  It was a real problem, but did not 
keep me from making any contacts.

So the question I have is if the software can be written such to map out or 
take the spurs off of one SDR, and this software is the same on multiple 
SDRs in the same shack, will the spurs from these still interact, or will 
they really be gone on all of them no matter where they are tuned.

As for spurs below xxx.100 -say 28.050 and lower...they are pretty numerous. 
Using a transverter to get say on EME and use these frequencies near xxx.025 
or so would be pretty tough I would think, but this could be alot of local 
noise / birdies that I have not eliminated too.  I don't have a real quiet 
location being in a residential neighborhood.

Again, my feeling is that the spurs are an issue, but as I have said to many 
others who have said that the SDR doesn't have "this or that" or has "this 
or that as a problem".I just tell them."the bandscope trumps all".  As 
for the spurs, I don't really see themI just look through them and don't 
process or something to that effect.

My 2 cents

[Flexradio] Fatal Error on 668

[Mike King - KM0T]

I get an out of index fatal error while the PowerSDR is loading, never gets 
totally loaded before it blows up.  This in on the latest SVN 668.  Was 
working with the previous SVN versions.  Anyone else get this or just me? 
Dont want to submit an official bug report if its getting fixed in SVN 669.

"Index was out of Range"  "Must be a non-negative and less than the size of 
the collection."  "Parameter name: index."

This is followed by lots of other error stuff.

Re: [Flexradio] Poor sideband suppression

[Mike King - KM0T]

Hi guys, this may or may not be a solution, and I know it has been beaten to 
death...but I too experienced this same thing over the weekend while I was 
helping a fellow with his SDR-1000.

He brought his system over and we got it all set up.  Going back and forth 
between our two systems and looking at each others signals, we too saw this 
opposite sideband or whatever it is come and go.  We also saw an opposite CW 
single in that mode.

After much messing around, we both pulled out, plugged in and twisted a 
number of times over our 3.5mm jacks on the back of the SDR-1000 for the 
delta 44 breakout box, and the opposite side signals went away.

We did not mess with the TX rejection controls whatsoever...

Re: [Flexradio] Sudden interruption of service

[Mike King - KM0T]

Hi, if you are running off the parrallel port of the computer motherboard, I 
too have experienced this on multiple machines.  A higher level of 
reliability can be found by installing a good quality PCI parrallel port 
card...that solved all my issues.  I then disabled the internal PP via the 
bios.  Lots of MB parrallel ports dont work, at least thats been my 
experience.  I have all my CPUs for the multiple SDRs I run configured with 
parrallel port cards.  I still get an occasional drop out on initial power 
up, but a recycle here and there, and it doesnt happen all the time, solves 
it for the rest of an operating session.

Re: [Flexradio] Sudden interruption of service

[Mike King - KM0T]

Roger on all Crit, I have however found differences between various cards in 
terms of how well they worked.  A few cards did not really seem to make a 
difference.  I got mine from www.byterunner.com  (I have no affilation) and 
those are the cards I now use.

I helped a budding SDRer  over last weekend and set up his SDR / computer / 
software and he was having the PPort issue.  I told him to bring a good 
PPort card along.  He brought one, made by someone I had never heard of...I 
just tried to call him on the name but no answer.  However, that card held 
even better then the ones I had so I was jealous :)

Hey Ken, concerning your comments on the Legacy issue and the PPort booster. 
Well I got one of those and was never able to get it to workmight have 
to look it over again.   Did you end up with one and trying it?

My experience with the USB adapter is that it put lots of noise down in the 
lower part of 28.1, which a huge problem for me, so I went back to PPort. 
If someone could show me that it doesnt add to the noise floor, I would 
consider it for sure.  Im just not convinced at this point.

As for the +/-3V swing in the new PPort standardis there not a 
replacment chip that one could put in the SDR that is for those voltages, a 
one for one replacement?  A guy can hope I would think?

Everyone have a nice weekendCrit good luck with your issue, not sure 
what else to suggest other than a better / shorter cable perhaps?

Re: [Flexradio] clock ticking from sdr-1000

[Mike King - KM0T]

Morning guys, I was told the ticking comes from the internal tuner, as it 
does not get completely powered off.  Just look under the cover and you will 
see a LED lit up when the SDR is off.  At least thats what I found.  I got 
annoyed with it, so I came up with a way to disconnect power easily from the 
radio.

[Flexradio] Looking into VAC

[Mike King - KM0T]

Hi all,

Im looking to get WSJT going with my SDR-1000, via using VAC.  Now I know 
Phil is working on something awesome, but Im going to go with VAC 4.03 for 
now and then get Phils interface when it comes down the road.

Questions:

Any issues with ordering this online from software.muzychenko.net? And then 
the credit card payment via the Regsoft site it is directed too?  Just 
wanted to check with you all to see if there have been any issues before I 
submit the ccard info..

Also, I hear that 4.03 is supposed to work fine, anything else I should 
know?

PS - I updated my SDR website page, some good stuff there on a simple 4 band 
UCB that I built.

Thanks,

Mike - KM0T

[Flexradio] Ready to take the programming plunge

[Mike King - KM0T]

Well, all this programming talk has got me kind of excited about 
modification to PowerSDR - just for grins or whatever, maybe disable my 
S-meter or something...

Anyway, I would like to confirmI believe I read that one needs Visual 
studio 2003.

Not knowing much about all this, do I need like the "pro version" or 
whatever...just want to make sure I get the right product.  So a bit of more 
specific info here is appreciated if warranted.  Is ebay the way to go on 
this?

Then, is there something else that one needs to do it in terms of software. 
Any pitfalls, etc.  Need .net 2.0 or whatever installed too?

Then Im wondering on the basic procedure.  Like the basic steps.  Open code, 
edit code, compile, build, whatever the jargon of the day isjust to get 
me in line when I start digging into this.  Does anyone have a basic 
proceedure write-up on this specific to PowerSDR?

Anyway, thanks for helping a software newbie out...

Re: [Flexradio] SVN numbers

[Mike King - KM0T]

I just did the svn update as well, tried to read the log since SVN 701 to 
722, it says that the revision for 721 is not there and it dies, so I am not 
able to see the comments from the revisions...just wondering.

Also, it updated the software, but the SVN it runs still says SVN-701, so is 
it really 722 or did I miss something?

Re: [Flexradio] Price Increase and 1 watt SDR discontinued

[Mike King - KM0T]

Why?  Is it that big a deal to build a SDR-1000 without the 100W amp, heck 
its built modularly anyway.  Some VHFers with transverters dont want the 
amp, I know we are a small minority, but is there something else?  Does that 
mean that the 1 watt SDRs may never get the forward power meter working in 
CW in a future PowerSDR version?

[Flexradio] KM0T website update

[Mike King - KM0T]

Hi all, I have updated my SDR page with some solid modifications to a few of 
my "1-watt" SDR-1000s.  Some of you may find this info usefull.  It is at 
the bottom of my SDR page.

Highlights...elimimate the 3.5mm connectors...put the Delta 44 breakout 
board "inside" the SDR...eliminate the RFI and ground loops..all good stuff.

Also,  I have provided my writeup version of interfacing VAC 4.03 with WSJT. 
This may be useful to some folks as well.  The link is on the main page.

As for the 1-watt SDR-1000 going away on Feb 1, sure Im bummed.  But if 
something better is coming out, great.  But being in the dark is hard for 
sure, but it is totally understood even if it bites.

Good luck to you who have some upcoming descisions to make.

[Flexradio] Meter Issue

[Mike King - KM0T]

I used the multiple SDR-1000s over the weekend for the January VHF SS 
contest.  All went well.  One thing in terms of the S-meter getting 
stuck

Two computers ran Version 1.8, the S-meters never stuck, the computers and 
SDR-1000s got hit really hard for 30+ hours.  These two computers were 
running XP-Pro and XP-Home, Regular Intel P4 processors with 2MB Cache.

The other computer was running PowerSDR SVN 830.  The S-meter stuck several 
times over the contest.  It took a restart of the software to get it going 
again.  The last 6 hours of the contest I switched back to version 1.8.  The 
meter got stuck again right away.

The difference here was that this computer was an older dual core 2.8 
processor and running XP Media Center 2005.

Im not sure this points anywhere, but it is some data on this issue.

73

Mike- KM0T

PS - all other functions worked great in PowerSDR 1.8 or SVN 830.

Re: [Flexradio] Computer requirements

For what its worth, I run XP Media Center 2005 on one of my SDR computers. 
It is a old dual core 2.8 GHz.  (Dell XPS 400).

I run an internal Delta 44 sound card for SDR-1000, and use the on board 
sound card for music, tv card, movies, etc.  It all works fine here.

Re: [Flexradio] Computer requirements

Hey guys, I run 48 or 96Khz, and use VAC also on that computer.  No glitches 
(yet)

In addition, when not using VAC, I can run all my fun stuff at the same time 
Im running the SDR-1000.  i.e. TV card, etc.

Not sure what I have done different than any of the rest of you.  I just 
recall using drivers for the delta 44 from the M-Audio website a year or so 
ago.  Installed it all and it worked.

Re: [Flexradio] Waterfall

[Mike King - KM0T]

Eric, the water fall looks great, thanks much!

Can we get a independent refresh rate that only applies when waterfall is 
selected.  That way we can keep the main panadapter screen refresh as it is 
set, not having to change it to a slower speed when waterfall is selected. 
Looks like there is room there in the waterfall box for another FPS box.

Just wondering.  Thanks.

Re: [Flexradio] single line-in/line-out cable

[Mike King - KM0T]

Hi guys, for what its worth, I updated all my SDR-1Ks with the D44 breakout 
board inside the SDR enclosure.  On the first one, I only did one jumper for 
the ground path, afraid of ground loops.  On the other three, I decided to 
add extra jumper bergs for all ground paths on the D44 breakout board.  By 
default when I installed them, I put the jumpers on all paths.  I never 
experienced any ground loop problems, so I just left it as is.

Re: [Flexradio] UCB Info

[Mike King - KM0T]

Steve, sorry that I did not get back to you on this before, your earlier 
email got lost in the shuffle here.

Here is the spec on the relay I used:

K&L  MP-43255-1

It has three inputs labled 1,2 and 3.

It also has a 12V post and a -C post (which I assumed was ground)

It has one common SMA and 8 SMA switched ports.  Voltage off of the unit 
makes all 8 ports open.  There is no "failsafe" on this relay.

Grounding one or any combination of the input posts gives the BCD 
information.  Otherwise they hang high at 5V.

There is another number stamped on the relay.  50140 and D.C. 9351

If I recall, I was never able to find any data on this K&L relay, as years 
ago I believe they were bought out DowKey.

This of course is a BCD control scheme relay.  Other relays out there that 
are "one for one" control will work just fine too.  Just need to use the UCB 
relays to switch the voltage to the control pins.  Most are 28V and that 
should not be a problem for Phils UCB.

Again, sorry for missing your first email to me.

73 and GL - let me know if there are any other questions.

Re: [Flexradio] Frequency for CW and SSB

[Mike King - KM0T]

Well, here is my 2 cents.  It may be a nuisance in general operating but its 
a must for weak signal microwaves as well as DXing.  If its a problem for 
mixed mode, its because everyone has differnt radios or set ups are 
different.  If everyone had CWU and USB or CWL and LSB then it would 
normally alway be ok.

A perfect example was yesterday afternoon.  6 Meters was open to the east 
coast to the Caribbean, but here in the midwest, the DX was coming in very 
weakly and had lots of QSB.  I spent considerable time watching a station 
and calling him on SSB.  Most guys were calling on SSB, a few were calling 
on CW.  The ones calling on CW were not being responded to by the DX.  Why 
you ask?  Did the DX not want to work cw?  Nope, all the CW was outside of 
the SSB passband.  Easy to see on the SDR-1000 bandscope.  It was obvious 
that the DX was not even hearing the CW.  These were stations with rigs that 
did not have the CW freq offset function when switching between SSB to CW. 
i.e. you would have to retune in order to hear it.

With no luck on SSB, I gave one call on CW.  DXCC #77 on 6M!  He came back 
to me on SSB without retuning to hear my signal.  We worked cross mode with 
no effort.  I just laughed when I saw other guys again calling on CW, just 
outside of the lower end of the SSB passband...I tuned away know that the 
funtion does what it is intended to do.

A few other rigs do it correctly.  Typically the Yaesus do just fine.  The 
Icoms did not until the Pro II I believe, and then yet you had to set it up 
that way.  They would have CW on the LSB side when you were on a band that 
utilized USB.

Other examples from the microwaves and weak signal work, we would try to 
work on SSB and say the signals QSBed out.  You knew the guy was there, so 
we typically switch to CW.  The guys with yaesus driving their transverters 
or whatever would pop out right where you needed them to be without tuning. 
I can recall many times loosing guys who I knew were running Icom 706s, etc. 
The fact of retuning to find a weak signal was normally a loss of a possible 
contact.

This is why I ran Yaesu radios for my VHF and microwaves 
IFser...uh.until the SDR-1000 came along of course :)

Again, my 2 cents.

[Flexradio] Flex 5000 Info

[Mike King - KM0T]

Hi all, is the "info" button for the 500 in the menus gone from the main 
screen of PowerSDR?  Im looking for the voltage monitor window and it is not 
showing up.  Did I miss something here or is it disabled for a bit?  Using 
V1.10.4 SVN here.

Thanks!

[Flexradio] VAC question

[Mike King - KM0T]

Hi guys, thanks for the key sequence for getting the info window, I must 
have missed that, appreciate it all.

Anyway, Im thinking up upgrading to VAC 4.08 for my 2 Meter WSJT and JT65 
work with my SDR-1000.  Have there been any issues with VAC 4.08 and 
PowerSDR that anyone knows of for updating?  I searched the KB for VAC 4.08 
and came up with nothing.

Just wondering, thanks!

Re: [Flexradio] RE :K6JCA latest console

[Mike King - KM0T]

Jeff, I think we all mean that we LOVED the old yellow backlit meter like 
from an old FT-101 or something.  Having it in a seperate window was very 
cool!  At least thats my vote!

73 and keep up the great work there.

Re: [Flexradio] Flex 5000

[Mike King - KM0T]

Hi guys, One more thing to add here that might be related...

I hooked up my 6 meter transverter the other week and used it for an 
extended period a few times.  What I noticed was a relay "clicking" every 
once in a while when I was in TX mode.  I did not see any unusual operation, 
but I suspected that a PC board relay was dropping out and in very quickly 
that might be in the XVerter jacks tx/rx chain.

This was when I was in transverter mode - split IF.  Since the power levels 
are so low and the power is not run thru the tuner to determin SWR, nothing 
really shows up.

But I felt that it was happening so quick that the guys on the other end 
never mentioned anything about audio/signal drop outs.  The relay clicking 
in the Flex-5000 did not translate into loss of PTT signal, the transverter 
and amp remained keyed during these periods...and I do not use VOX.

Just a thought.

Re: [Flexradio] Use of Peak Display Mode

[Mike King - KM0T]

Rob, it works good for sure.  I had an experience a few weeks ago doing just 
that.   If you care to read about that, its on the main page of my website, 
picking up extreamly weak 24 GHz rain scatter.  Its under the current news 
portion near the top of the page.  The split screen utilizing the waterfall 
is very helpful as well.  I have found that with the waterfall, one can pick 
up on a frequency a bit easier than looking at the avearge signal in some 
cases.  The peak function does about the same thing.
