[Flexradio] Help with DDUtil!

[John Hansen]

I've done a search of the knowledgebase, but I can't find anything that
covers exactly what I'm trying to do .  I know lot's have you have done
this before and so I would really appreciate it if you would send me an
email with your setup.  Here's where I'm at so far

1. I've got PowerSDR working with HRD with full CAT control no problem.
I'm using the N8VBvCOM driver to do this.

2. I recently installed a Steppir beam, and have it working on Autotrack
with a different serial port.

3. I want the freq data from the radio to go to both the Steppir and HRD,
but am having trouble configuring DDutil to do this.

4. So the bottom line is that I can have the radio data go to HRD and I can
have the radio data go to the Steppir controller, but I want it to go to
both.  I understand that DDUtil is supposed to do this, but I'm having
trouble getting it up and running.

What's your configuration that you've been able to successfully do this?

Thanks,

John W2FS

Re: [Flexradio] Controlling Power SDR with iPad Article

[John Hansen]

Do be careful doing this.  I purchased the software and when I loaded the PC
component (on an XP machine) it gave me the BSOD and then immediately
rebooted the machine. I had to boot into safe mode and do a system restore
to recover.  I'm suspecting the issue might be related to the fact that I
have two video cards and 4 monitors connected to the PC.

Re: [Flexradio] Serial Ports

[John Hansen]

I've never actually tried to use ports where they suggested these numbers,
but the system does initially assign port numbers higher than 255.  I can
look up in the Device Manager and find the new com port with an assigned
number of COM562.  As I approached 255, I too thought it would stop
incrementing... and maybe choke... but I was surprised to see it blow right
by that number.  I believe someone once mentioned to me that there is a way
to reset this value, but off hand I can't remember what it was. But the
numbers do keep incrementing past 8 bits.

Re: [Flexradio] New BEST motherboard alert!

This is really interesting stuff.  But on the NewEgg page, I don't see any

[Flexradio] Question on Flex-5000 and Steppir

[John Hansen]

Hi Folks:

I'm about to buy a Steppir antenna to go with my FLex-5000.  This used to be
a pretty simple matter where you just placed an order for the antenna you
wanted.  Now they seem to be offering an array of transceiver interfaces
(none that specifically mention FLEX, though) and upgraded controller boxes,
etc.   All I really want to do is have the antenna adjust automatically as I
change frequency on my 5000.  Can someone who's using this combination offer
a suggestion as to what, aside from the antenna (a Yagi) and cable I will
need to have this work with a 5000?

Thanks in advance.

Re: [Flexradio] Griffin power mate

[John Hansen]

I agree with Ray on this.  I bought the Griffin before I bought my
first Flex (largely in anticipation of getting a radio to use with
it).  When I finally did get a Flex, I found my whole way of looking
at radio operating changed.  With a conventional radio you tune with a
knob in your hand and detect signals solely by ear.  With a flex, you
identify signals both with your ear and (even more so) with your eyes.
 So the days of continuously tuning up the band to get a feel how many
stations are on are largely gone.  You can see that without all the
tuning.  I tend to click on interesting portions of the spectrum with
my mouse and then then use the wheel on the mouse to tune around.  If
you use the Griffen, that requires that you move your hand back and
forth between the mouse to the Griffen.  It seems more awkward.

Having said that, it does make a wonderful volume control.  In
addition, the pulsing blue is really nice.  So if you are getting one
for free or cheap, don't just shelve it, try it in both applications
and see what you think.

Re: [Flexradio] Quickplay Rec/Play files sound like static

[John Hansen]

This seems to come up a lot on this reflector.  As nearly as I can tell
here's the basic problem.   When Flex implemented this feature, they only
envisioned it as being used by someone who wanted to record audio off the
air and then play it back over the air.

For many of us, this is not why we would want to record audio off the air.
We record it so we can replay it and hear it again (not over the air).
Quite some time ago I experimented with this and found the same problem that
was noted by Larry.  I entered it into the bug tracker as a bug.  I heard
back from Flex, saying that it wasn't a bug; they had, in fact, designed it
this way.

You can replay the audio so you can hear it by using your mouse to click in
the Panadapter display after you push the "Play" button.  I do wish flex
would implement a second button that would allow you to play back audio
without jumping through the extra hoops.

Re: [Flexradio] Price Increase In The Uk

If the dollar weakens, that causes US exports to other countries to be

Is this superior to using Norton Ghost and if so, why?  Also does anyone 
know of any PC software that will do what Apple's new "TimeMachine" will

Re: [Flexradio] Spurs on 20m

[John Hansen]

I think it must be repairable because version 1.6.2 of the code doesn't 
have them... at least not the ones around 14.3 MHz on 20 meters. It does 
seem to me that it's a pretty serious problem.

[Flexradio] Receiver became deaf?

[John Hansen]

Hi:

I've had a SDR-1000 for a little over a year.  Recently it has stopped 
receiving signals.  I can pick up a local AM broadcast station, but that 
is about it.  Unless the pre-amp is set to high, even this local station 
is in the noise (and it should be pegging the meter).  I'm certain the 
problem is not with the antenna because when I hook it up to my IC706 it 
receives normally.  Is there something that I should check locally 
before sending it in for repair?

Thanks!

John W2FS

Re: [Flexradio] ANF

[John Hansen]

I have this same problem and have been meaning to post about it for some 
time.I notice that the notch filter works reasonably well when a 
signal is in the clear, but when it is on top of an SSB signal, the 
notch filter is not very effective.  I've been assuming that this 
relates to some DSP settings that I need to tweak in order to get this 
working better.  It would be a real service if someone who is having 
good luck with their notch filter would post the settings that they are 
using.

Re: [Flexradio] Suggestions to stop "popping" while in receive.

[John Hansen]

Larry:

I've had the same problem for some time now and I don't think it is a 
hardware (computer) or configuration issue.  The reason I say this is 
that when I switch to the K6JCA console or the official release 1.6.2 
console it goes away.  The CPU utilization is about the same regardless 
of which console I'm using but the popping shows up only on the later 
versions of the software.  I've looked at the settings on the K6JCA 
console and on the latest SVN version and made sure they were the same, 
so the problem isn't related to to the way the buffers (or anything 
else) are configured.  So if none of the KB articles provide you with 
any joy, you might try dropping back to one of these other software 
versions.  When they release version 2 of PowerSDR if the problem is 
still there, I'll probably have to address it, but for now, I simply K6JCA.

Re: [Flexradio] Using a Steppir with the Flex

Does this mean that CAT is then not available to be used in conjunction

to be a way to route CAT data to both a virtual serial port and a "real" 
serial port, but I can't see how to do it.

Re: [Flexradio] Frequency Calibration on Recent SVN's

FWIW, I found that if I used the WWV signal at 15 MHz the calibration 
procedure appeared to work.  If I try it at 10 MHz, I get the error 
referenced in my previous message.  The 10 MHz value appears to be 
broken in the current SVN version.  Thanks, everyone, for the suggestions.

[Flexradio] Frequency Calibration on Recent SVN's

[John Hansen]

I noticed that the frequency calibration was off on a couple of the 
recent SVN's (WWV at 10 MHz was about 20 Hertz low).  So I tried to run 
the frequency calibration routine.  When I do this I get a pop message 
box that says, "Peak is Outside Valid Range."   I don't have this 
problem with 1.6.2.

I know there is a proper place to report bugs and I know this newsgroup 
isn't it, but I'm not sure where the proper place is.

Re: [Flexradio] More on Audio Problem - Sample Audio

[John Hansen]

First I want to thank everyone who has offered suggestions concerning my 
audio problem.  I appreciate the suggestions that a number of folks have 
made about getting a mixer and I expect to do that soon.  It would be 
nice to have the audio controls all in front of me as knobs in any 
case.  I also appreciate the suggestions that folks have made about 
plugging the mic directly into the sound card and if I can't get this 
resolved in the next little while, I'll certainly try that.  However, I 
sure would like to be able to use the PTT button on the mic (yes, I know 
I could cobble something up to connect it separately) so I'm going to 
put off trying that unless and until I've completely explored the 
possibility of using  the front panel mic connector.  In any case, I can 
get enough audio into the radio to get a 0 db peak on MIC meter (with a 
setting on the MIC control of about 60 or 65), so it seems like I 
shouldn't absolutely need a pre-amp to get this to work.

I did rewire the mic, and this seems to have pretty much eliminated the 
hum, so I have some hope that it may be possible to sort this all out.  
Today I made some recordings of the audio that I am getting through the 
radio.  I made these recordings using the PowerSDR monitor and the 
PowerSDR record function (using the post processed audio).  I then 
converted them into mp3 files (so they wouldn't be too large) and 
attached a readme file to describe the conditions under which each was 
made.  The recordings can be found here:

http://www.coastalchip.com/audio.zip

Note that while the monitor had to be turned on to do the recordings, I 
disconnected both headphones and speakers to ensure that this wasn't the 
result of audio feedback through that route.  I also checked the audio 
against what I'm copying in a second receiver (an FT817 with no antenna 
attached) and they sound similar.

If those of you who have some expertise in this area could take the time 
to listen to these and see if they shed any light on my problem, I'd 
sure appreciate it. 

Thanks again,

John Hansen W2FS

Thanks for the suggestion, but that's not it... all the cables are well

Thanks,

Re: [Flexradio] More on Audio Problem

[John Hansen]

Thanks for the assistance, John.   I'm getting really close to solving 
this problem.  I rewired the cable and the hum is now gone.  I'm not 
sure exactly what I did wrong the last time around, but I'm pretty sure 
that part is now good.  The audio also sounds good both on the PowerSDR 
monitor and on my 2nd receiver.  Except for one thing I can hear two 
voices in both the monitor and in the receiver (note I'm monitoring with 
headphones, so I'm reasonably certain that this is not an audio feedback 
problem).  In addition to my normal voice I here a second voice that is 
very low pitched and sounds like it is on the wrong sideband.  Also, 
strangely enough, it is delayed by a few milliseconds from my normal 
voice.  I thought this might be an image rejection problem and I've been 
playing with the transmit image rejection controls but no change in the 
settings of those controls seems to have much of an effect on it. 

I can tell this audio is going to sound fabulous when I finally get this 
last issue resolved.  I really appreciate your patience in working with 
me on it.

Upon further reflection, the problem is not just a hum.  There is a weak 
hum in there, but there is also what sounds like feedback it goes 
thumpa thumpa thumpa however I do have the monitor off.  It 
continues even when I turn the radio off that I was using to monitor 
it at that point I can hear if very weakly thumping in my monitor 
speaker (even though it's on mute).  When I turn the mic gain down to 0 
it has no effect, but if I lower my power to a setting under 30 it does 
go away.  I do hope this isn't an indication that RF is getting into 
this because with all these wires running around here it's going to be a 
mess to straighten out.  BTW, I do not have this interference on CW or 
on the digital modes using the VAC.

[Flexradio] Gold Line mic and SDR-1000 = hum? No help from isolation transformer

[John Hansen]

Ok, I admit it, audio is a complete mystery to me.  Give me a digital 
circuit any day.  I'm trying to interface a Heil Goldline mic with the 
SDR-1000.  I had previously used this mic with an ICOM 756, and the 
cable was originally wired by Heil, so I looked up the pin outs on the 
756 to confirm which wire in the connector did what and then rewired the 
8 pin plug so it had the proper pin out for the 8 pin jack on the 
SDR-1000.  Audio comes through just fine, but there is a hum.  The hum 
increases with both mic gain and power output on the radio (I'm 
monitoring this on another receiver).  When I have the power turned up 
to full on SSB and the mic gain adjusted to produce 0 on the mic meter, 
the hum will result in about 1 watt of power being transmitted when no 
audio is going into the mic.   This is not horribly loud, but I have the 
sense that it will be noticable on the air and it shouldn't be there.  I 
wondered if I had the grounds reversed, because on the Heil cable the 
shield was mic ground and the black wire was PTT ground, but reversing 
these didn't seem to make any difference.

I tried two kinds of audio isolation transformers.  I went to radio 
shack and bought one of their 1:1 audio isolation transformers and put 
it in the cable just before the mic connector.  The result was that I 
still had the hum, but almost no audio was getting thru from the 
microphone.  I wasn't terribly surprised by that... I've solved ground 
loop problems in the past by using two of the RS 1000 ohm to 8 ohm 
transformers back to back, but I've never had much luck with their 1:1 
transformer.  So I took the isolation transformer back and bought two of 
the 1000 ohm to 8 ohm transformers and wired them back to back.  Same 
result... hums still there but the audio is very reduced to the point of 
not being heard.

I tried checking the DC Block option on the TX setup menu but that 
doesn't seem to have had any effect either.

Has anyone successfully used a Gold Line mic with this radio?   Anything 
I'm missing here? 

Any advice would be appreciated!

[Flexradio] Difference between 3.12 and 4.02 of VAC?

[John Hansen]

Since version 3.12 and 4.02 both work with the SDR-1000, and the 
registration price on 4.02 is 50% higher, is there any reason to buy 
4.02?  Aside from the fact that it is 64 bit compatible, the Release 
history only says "fixed some bugs".  Does anyone know whether any of 
these were significant for SDR purposes?
