FDR, SDR ; tomato, tomahto

The FCC in 2005 modified its definition of a software-defined radio as follows:

"a radio that includes a transmitter in which the operating parameters of 
frequency range, modulation type or maximum output power (either radiated or 
conducted), or the circumstances under which the transmitter operates in 
accordance with Commission rules, can be altered by making a change in software 
without making any changes to hardware components that affect the radio 
frequency emissions."

Wouldn't conventional radios including the K3 be better defined as a
"Firmware Defined Radio FDR"?

The only sure way I have found to keep the spammers at bay for several months
(even with ISP filtering) at a time is to change the format of my basic email
address by inserting/moving numbers in place of letters when I begin to see a
buildup of that junk.

That, in turn, requires me to change a lot of reflector info.

IMO, If it ain't broke, don't fix it.  I can find most, if not all email
addresses I might need either on QRZ.COM or through the FCC data base.

[Flexradio] DUMMY MICROSECOND

[Philip M. Lanese]

Bob
You are ABSOLUTELY correct on the "Dummy Microsecond".

In 40+ years of designing commercial control systems, on only three occasions
have I been able to run a top-down design (I owned the company) without having
to re-design major portions of the systems.  I coined the phrase "instant
experts" to describe people who come up with a "small change" that must be
incorporated.

I am coming out of retirement now (at an atrocious salary) because a company
decided they could "just move some stuff and lay out the patch antenna on the
PCB", forgetting (or not knowing) about 'fringe effects', etc.

[Flexradio] THANKS & CLARIFICATION

[Philip M. Lanese]

Dale
Thanks for reposting my reply - I forgot you were already in my address book so
the response did not get posted here.

and,

Bill (kd5tfd), you are not an "instant expert" if you make inputs BEFORE design
work is well underway.
It's typically commercial marketing people who have not done (or can't do) their
job and who have little knowledge of the technology and work involved, but a lot
of clout with upper management, that come up with the 'gotta haves' half way
thru the design effort that result in time consuming redesigns.  If allowed, the
product usually does not get to market in time and/or is no longer cost
effective.  And guess who gets blamed!

What is going on here is the Pre-Project Market Analysis that is so important to
producing a useable product in a reasonable time frame with minimal time (and
cost) overrun.  Even when technology does not yet exist to do some of the things
people would like to see, 'hooks' can be planned into the software and hardware
design 'up front', if the project planners have an inkling of what people in the
intended market would like to see.

[Flexradio] DELTA44 ON VHF & UP

[Philip M. Lanese]

For those using (or considering) the SDR1000 as an IF system for VHF & up with
the DELTA 44 sound card, I highly recommend checking out the modifications (and
analysis) that Leif, SM5BSZ, has on his site
www.sm5bsz.com/linuxdsp/hware/delta44.htm.  The analysis, mods and high
resolution images can be found on Leif's site.The modifications clear up
ground loop, regulator, and input amplifier noise contributions that degrade the
noise figure,  S+N to N ratio and dynamic range of the card when used for the
VHF and up bands.  See especially the analysis & simple cure for ground loop
noise caused by the built-in error in the input amp. stage design.

[Flexradio] DXPEDITION & EME

[Philip M. Lanese]

Eric wrote
>
What might be doubly interesting is looking into taking (e.g. ) gear for
1296 and trying out moonbounce. That's beyond my current capabilities,
but it is something we could dream about and maybe make happen. Or,
maybe something surer like 6 meters during the Leonids or Persids (if
one of those is near a contest).
>
1296 might be pushing a bit Eric.  A more achievable goal would be 2 Meter EME
using a modest (and allowed in most jurisdictions) 100 Watt SS Brick, a single
10 or 12 element yagi and WSJT65 mode B.

Single yagi to single yagi QSOs are possible on 2M with WSJT.  There is
considerable Doppler shift on the UHF and microwave bands and unless you are
able to easily hear other stations (read LARGE array or dish), tracking the
Doppler shifting signal would be difficult.

 The SDR1000 is a very good IF radio for WSJT with a good, low noise
preamp/transverter combination.  The following is a snip from a WSJT QSO I had
with Keith, G4FUF on 2 meters, running single 12 element yagis at both ends.

020800  1  -23  4.4   67  2 #  K3IB G4FUF JO01OOO0 10

 The '1' indicates the signal was near WSJT's threshold of detection and the
'-23' is the strength of the signal in dB relative to the received noise at the
time, but the '10' at the end indicates that the WSJT program was totally
confident in the decode.

A benefit of such a set up would be the ability to work Meteor Scatter on 6 or 2
Meters out to 800 - 1000 miles almost any time of the day or night as the JT441
mode makes contacts possible when there is only the usual dust particles
entering the atmosphere.

Re: [Flexradio] FW: Yikes, I got Spikes

[Philip M. Lanese]

After trying every trick known with a similar problem when I first began using
the SDR1000, I finally ran a separate AC circuit just for computer equipment and
connected all PCs & peripherals to 120vac thru a 1.5 KVA isolation transformer.
All the equipment in the shack including computer cases is now connected
directly to the earth ground (10' copper rods) system around the outside of the
house and the Electrical Service ground at the Service Entrance with #8 and #4
stranded copper wire.  Problem was immediately corrected and has not returned.

One big source for ground loops in systems having multiple AC powered
devices is the "protective earth" (the third wire of the power cord).
In the PC and many power supplies, the PE of the AC service is tied to
the metal chassis and that is tied in turn to the "ground" and/or
negative DC terminal.  You may wish to investigate and either start
clipping shields on audio cables at one end to guarantee only a single
return path exists or selectively "lift" the ground on the AC power cord
of a single device.  The latter is a delicate issue with respect to
electric codes, safety, etc. and should only be done for investigatory
purposes (wink wink).

The same issue has existed for "centuries" when one is attempting to
make precision measurements of small/HF signals using oscilloscopes.
Tek used to sell fancy AC supply isolation transformers that would float
AC supply and lift the ground of the scope since it was tied to the
chassis and PE of the AC service.  Nobody used them; they would just
clip the PE on the power cord and make sure not to stand in water,
barefoot, while using the scope.

It's also the reason "real" analog engineers stand around with one hand
in their pocket.  Everyone just took for granted we were some form of
deviant, when in fact it was a based upon a safety issue! (Many still
are some form of deviant irrespective of their proper safety habits).

[Flexradio] 1.3.10 EXT PTT INPUT?

[Philip M. Lanese]

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 SDR
into Tx.

[Flexradio] ON AIR TEST

Re: [Flexradio] ON AIR TEST

[Philip M. Lanese]

Hi Frank
Evenings & weekends are no problem, weekdays are a problem right now.  The QRL
has me tied up designing 2.4G patch & 130 kHz loop antennas & quashing big EMI
emissions in the VHF aircraft band from a 'new' product already in production.

I usually get home around 7:30 - 8:00 and monitor 144.200 with the SDR & 144.220
with the IC756 Pro2 split off the 2M transverter + 50.125 direct to the 6M5X
while I fill my HD up with all the Q&A posted here (still have 24 more to read
tonight).

I thought it might be helpful to hear what 'new' code sounds like on the air, as
a last check before posting or if there is a bug reported that could be fixed
faster/better if you hear/see it.  I can do wav recordings & audio spectrum
captures using Spectran on the #2 computer patched from the SDR audio output &
limited only by the ability to rapidly switch from any selected narrow BW U/L
SSB/CW/AM to +/- 9.999 kHz BW DSB  to answer Eric's question on the need to
keep 2 x VAR buttons.

[Flexradio] CW vs SSB PEAK OTPUT

[Philip M. Lanese]

Just did a quick test using my Agilent 4402 Analyzer & commercial 0.1 to 1.0 GHz
Log Periodic Test Antenna to sniff the air while I transmitted.

With the analyzer in peak hold mode, sending CW dashes after calibrating Tx
output with TEST to 1500 W, the analyzer displayed the peak of the RF envelope
at  (-) 10 dBm at 144.150 MHz.  With a peak reading meter connected to an
in-line Bird dual dir. coupler, I got a forward power reading of 1000 W.

Switching to SSB and speaking into the D104 with my normal voice, the analyzer
displayed the peak of the RF envelope at  (-) 13 dBm.  The peak reading meter
wiggled up to ~ 400 to 500 Watts forward power.  With the meter switched to
measure Average, I got a reading of 150 W forward power.

When I get a chance, I will re-run the test with my laptop USB connected to the
analyzer and download the displays to MS WORD.  I can then try to post the
results or I can e-mail them to someone who can post them somewhere else.

[Flexradio] CW PROBLEM IN 1.3.13

[Philip M. Lanese]

Today must be Friday the 13th!
1./  TX SSB, VFO = 28.150.000 => 144.150.000 MUCHO Avg PWR with Peaks at 1500W.

2./  Change to TX CW, VFO = 28.150790 => 144.150790

3./  TX output is displayed at 144.149.250, -15.1 dBm with calibrated test
antenna & E4402B.  No spurious
   outputs up to +/- 100 kHz but there is carrier leakthru at 144.150.000
with key up at -60dBc.
  This is Lower Sideband CW not Upper Sideband CW.

4./  Set SDR for CWL.  VFOA still displays 28.150.790 and nothing goes out on
the air but clicks.  Analyzer
  displays CW (dashes) peak at 144.150.075, -15.1 dBm BUT now there are
major splatter peaks up to
  +/- 50 kHz from 144.150.000 at up to -30 dBc.

Returning to CWU produces same output.  Console is locked in this mode.
Shutting down console and restarting allows returning to 1./ above and the
process can be repeated.
Analyzer displays available via e-mail if wanted.

[Flexradio] CORRECTION TO POST RE CW PROBLEM IN 1.3.13

[Philip M. Lanese]

After several repetitions, the spurious outputs are no longer being shown on the
4402B.  Just one clean carrier at 144.150.790.

>4./  Set SDR for CWL.  VFOA still displays 28.150.790 and nothing goes out on

Also while testing got a call from KB2RMX in Baltimore (30+ miles south and 90
degrees off main lobe) that the audio was clear and clean but no 'S' meter
reading.  With antenna pointed at him report was that audio was still very clear
and "nice" sounding and 'S9 + 60 dB'.

Title: RE: [Flexradio] Linux, pyhw(2) broken



Bob
I tried to send this yesterday but the e-mail sys at QRL uses two different 
addresses for receiving vs. sending e-mail so the list rejected it.
 
If you have Win XP and Linux on the same machine, add a line to 
mount the windows partition/folder to the Linux boot file and the 
partition/folder will be mounted like any Linux file.  You can 
then R/W files on the WinXP partition from Linux.  I used 
the technique a lot when I all I had was a winmodem for my old dialup 
telephone connection.

[Flexradio] TRANSVERTER LLOCAL OSCILLATOR/SDR1000 CALIBRATION

[Philip M. Lanese]

FWIW, I first calibrate my SDR1000 at 28.150.000 with my HP 8640B locked to my
Ru source.  Then I calibrate the 2 Meter to 28 MHz transverter/SDR1000
combination by injecting a signal at 144,150,000.00 with the 8640B and
re-adjusting the /GENERAL/Calibration/Frequency = 28.150.000, Clock Offset
value, if necessary, to place the signal peak exactly on the center vertical
line using AM or DSB, SPECTRUM display and 100, 50 then 25 Hz band width.

The caveat is that the 116 MHz oscillator I use (6 yr. old prototype) is my own
TCXO design, heavily subsidized by an employer from a former life, and has not
had to be adjusted for the last two years, drifting only +/- 2-3 cycles short
term after warm-up.

This method takes care of Jim's steps 1 and 2 but not 3.

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

[Philip M. Lanese]

SSB audio report with 1.4.5 over long paths (> 300 mi.) on 2M.

Audio with 1.4.5 is reported to be clear and strong but does appear to have
digital artifacts.

The artifacts may be due to the newness of the program here and missing Tx audio
equalizer so it is not yet completely customized for my voice characteristics.

It did take me a couple of weeks to "get it right" with 1.4.1.

I also noticed that the XVTRs 'Power' setting overrides the main window PWR, in
that, adjusting PWR from the main window while transmitting is negated on the
next transmission unless I go into XVTR settings and change Power there to agree
with the PWR value I just set in the main window.  The two should be linked when
operating with transverters so the main display PWR modifies the individual XVTR
band selected but does not affect the PWR setting for switching back to the 'DC
bands'.

I am and have been using the 2M transverter I designed several years ago, not
the DEMI unit.  It is highly unlikely that serious VHF/UHF/uW weak signal
operators will ALL purchase DEMI units over their own designs and those of
Steve's competitors.  In addition, transverters built for higher bands usually
down convert to one of the lower VHF bands (typ. 144 or 432), not 28 MHz.

Re: [Flexradio] Split 28MHz Transverter RX/TX IF?

I modified my original 3 board set to do split Rx/Tx by removing the output
relay, cutting one jumper between pads under the relay, re-installing the relay
and then adding a second BNC jack wired directly to the trace on the PIO board
going to the input amplifier from the relay.

I am going to add the RFE board and make the ECO20, 25 mods this weekend, given

[Flexradio] e-ham gripes

Bob, et al

Reply All bounced so there may be two postings of this repl;y

Since I had a dozen or so LM309Ks left over from a long ago production run, I
replaced the board mounted regulator with the TO-3 chassis mounted 309K when I
"upgraded" to the black box and completely eliminated worrying about dissipating
heat from the regulator.  Wiring from the 309 to the board was easy and neat and
an in-line 3 pin Molex connector allows removal of the 'guts' to the lab bench &
power supply for 'tweaking & tuning'.

Nice working you on 2 Meters the other day.  Hope you appreciated the audio from
this 'griped about' radio.  I appreciated being able to hear you clearly in
spite of several dozen local stations on the band that had their mic and drive
controls "full on" to push the last watt out of their solid state brick
amplifiers, thereby producing
(-)10dBm, 60 kHz wide signals.  Something that just does not happen with SDR
thanks to the sweat of guys like Bob, Frank and others who contribute.

  Steve,
   
  Please respond directly outside this and we 
  should be able to get you up and running. I currently run the SDR1000 entirely 
  on VHF and it the best setup I've ever used. That said, I have not done any FM 
  what-so-ever on these bands with the transverter setup. My operating is 
  mainly focused on SSB, CW (using the internal keyer with a set of Bencher 
  paddles), and WSJT for meteors and EME.
   
  Mike, KM0T, has been using the SDR with VHF, UHF, 
  and SHF transverters in contests operating on frequencies from 6 meters up to, 
  and including, 24 GHZ.
   
  Your comment "I went to the DEMI site and 
  low all the 2 meter stuff they have is for 28 MHz IF. Oops that won't plug and 
  play with another device just like it. Drat, what do we do now 
  coach?"
   
  To get to the 
  higher bands that require a 144 Mhz IF, one ends up putting two transverters 
  in series  SDR provides 2Mhz, 2 Mtr transverter takes the 28MHZ up to 144 
  Mhz, and the final transverter uses the 144 Mhz as the IF for 902 Mhz 
  transverters and above.
   
  Several others on 
  here have this setup working. One choice is whether to use the 28 Mhz 
  drive from the 1 watt connector on the back of the SDR back panel or to 
  use the 1 mw level available from the RFE board. Either work, the RFE 
  connection gives the added function of providing the TTL voltage 
  necessary to switch the PTT line on transmit so that a single rf cable 
  between the SDR-RFE board and the transverter handles the 28 Mhz rf and the 
  PTT to the transverter. (my particular choice).
   
  Let me know what 
  you exactly are trying to do...

  W0VB

I had in mind to 
do some weak signal VHF/UHF work so I bought a 144-28FRS Transverter for my 
SDR-1000. Got it installed and the reality has finally set in that I don't 
know what I'm doing as far as taking the next step of having a usable 2

I went to the 
DEMI site and low all the 2 meter stuff they have is for 28 MHz IF. Oops 
that won't plug and play with another device just like it. Drat, what do we

I have come to 
the conclusion that unless I buy a transverter that has an 144 MHz output 
(900 MHz up) the internal 144-28FRS is of no use to me at all and I could 
have saved my money.
 
The question is; 
how is the best way to get on 2 meters with or without the internal 
transverter. I have looked for enlightenment on the Flex and DEMI sights and 
didn't find any advice for Dummies! I may add more transverters later 
depending on how this experience ends up .

Re: [Flexradio] SDR-1000 for EME ?

[Philip M. Lanese]

Hugh
I have been using my SDR1000 for EME  and Meteor Scatter (see Testimonials)
since July, 2003 with excellent results.  At first I only used the Rx capability
of the original 3 board set, transmitting with my trusty OLD TenTec Corsair (S/N
666) until I qualified the SDR Tx output power level and built the present
computer.

Since moving to my new QTH in July of 2004, I have used the SDR1000 exclusively
as the 28 MHz IF for my home brew 144, 432 and DEMI 1296  and 10 GHz
transverters.  I run both CW and WSJT on EME.

So far, I have been able to make at least one QSO every time I get a chance to
operate EME.  The station here is QRO on 144 and soon on 432.  I have been
"temporarily" using a single K1FO 12 element antenna on 2 Meters,  mounted 30'
above ground on my ROVER trailer with no elevation rotation.  Until I can get
some towers to grow so I can erect my 8x or 16x arrays, it is good enough for
EME, MS and Tropo work, with a tower mounted CAV144 preamp.  Feed Line is 25λ,
LMR 600F.  Antenna elevation here is 990' ASL with nothing higher for 30 to 50
miles in all directions, and with the antenna so near ground, I get SIGNIFICANT
ground gain at moon elevations of 9° to 22°.

[Flexradio] INSTALLING PREV. 2 UNHANDLED EXCEPTION, FATAL ERROR MESSAGES

[Philip M. Lanese]

Trying to install Preview 2 by importing  PowerSDR.mdb from Preview 1 folder in
Setup form resulted in monkeysoft .NET Framework reporting "An unhandled
exception  ' Specified argument out of range of valid values.  Parameter
name '2' is not a valid value for 'index'."

Since I had renamed the installed default PowerSDR.mdb file to PowerSDRP2.mdb as
a precaution, I deleted the imported PowerSDR.mdb file and renamed
PowerSDRP2.mdb to PowerSDR.mdb and tried to restart PowerSDR.exe.  I then got
the "FATAL ERROR..." box when start-up gets to "Loading Main Form".

After uninstalling and re-installing Preview 2 and NOT importing old Preview 1
.mdb file allows program to start and run but with all default values so next
step is to do it again and manually copy all Preview 1 values into the new
program after it is running.

[Flexradio] MORE FATAL ERRORS

[Philip M. Lanese]

After uninstalling Preview 2, manually deleting the icon and the folder,
shutting down and restarting the PC and re-installing Preview 2, I manually
copied all of my Preview 1 variables to Preview 2 and the program ran OK.

I closed PowerSDR and restarted the program and the Fatal Error message is again
presented when initialization gets to "Loading Main Form".  The only solution
seems to be to uninstall P2, shut down PC, re-install P2, start PowerSDR P2,
copy all P1 variables and operate but never shut down the PowerSDR console.

After a long & frustrating day of battling with the poorly designed and
supported Philips BGW200 2.4 GHz WIFI SDR on a chip, I have had enough radio for
today.

[Flexradio] 1.4.5 START-UP UNHANDLED EXCEPTION

[Philip M. Lanese]

Eric
I just went through a sequence of starting v 1.4.5 Preview 2 that seems to load
ok.  The sequence must be repeated on each start - up.

I made a copy of v 1.4.5 Preview 1, renamed it to "copy of PowerSDR.mdb" and
saved it in the v1.4.5 Preview 2 folder.
Deleted the old PowerSDR.mdb in Preview 2 folder.
Started the console and when setup screen came up selected import database.
Selected "copy of PowerSDR.mdb" and click OK
I get the Exception error that produces the text below.
Click continue and click OK again and the console starts with the correct
settings from 1.4.5 Preview 1 and runs fine.

Shutting down and restarting this way works every time with no "Fatal Error"
when start-up initialization gets to Loading Main Form.

Re: [Flexradio] 1.4.5 START-UP UNHANDLED EXCEPTION

[Philip M. Lanese]

AHAH!!
Just tried Klaus's suggestion and voila no fatal error on restart of the 
console.  Since the console was running when I read the posting I started 
the wizard from the Setup form and could hear the sensitivity drop (RFE bd is on 
the bench in the lab waiting for the rest of the boards to come and join 
it).  Shut down the console, restarted and no fatal error.
 
Thanks Klaus, was beginning to suspect oldsheimers was making a 
major advance here.

  Phil, Bob and Eric,
  here is another observation that might help 
  to find a solution: I use the 3-board-stack. When I configure for a 
  system with RFE-board I can start and shutdown the console without problems. 
  However, when I disable the RFE board in the General Tab to cheat the system 
  (RX is operational this way) - then the well known message appears after 
  restart. I assume you have the 3-board-stack configuration as well. So - 
  before you shutdown the console change the hardware configuration: activate 
  the RFE-board.

[Flexradio] PREVIEW 3 TRANSVERTER POWER NOT SAVED ON EXIT

[Philip M. Lanese]

Eric et. al,
No crashes on importing data base, no Fatal Error on restart with or without RFE
checked or unchecked with console running or in with console in standby.

Power set in XVTR panel is not transferred to Console PWR and both are reset to
50 on next start-up of Console.  If I import the database from Preview 1, then
power is set to 10 in both locations and is saved properly for the next start-up
of the console.

Other functions I commonly use appear to be OK [so far].

Re: [Flexradio] The New code is Outstanding on receive! Using VAC andthe Extigy Card

Good news.  I was up until 3 AM this morning following Bob's install notes on
VAC and could not get WSJT v6 to connect to the SDR/Santa Cruz.  Could only see
ports 1 thru 5.

First contact with Preview 3 last night was to base of Mt. Greylock ~ 300 miles
using the problem antenna.
100 watts each end, W2NTJ/1 signal was peaking 25 - 30 dB above the noise floor
(~ -150 dBm).

All the parts are out back for 8 x FO12.  Only need one helper & time - hi.

[Flexradio] CAT CONTROL CHECK BOX P3 & P4

[Philip M. Lanese]

When the CAT Control 'Enable CAT' checkbox is checked, the values are grayed
out.  When CAT control checkbox is not checked, values are black on white and
can be changed.  Is this correct or is my logic backwards from 4 days of
frustrating attempts at getting TeamSpeak, MixW, VAC, vCOM, SDR and  Vera Cruz
to play nice together?

Re: [Flexradio] EME

For EME you will want to spend your money on a good preamp and transfer 
relays located as close to the antenna(s) as possible and the largest antenna 
your property and wallet can support.  
 
After that, a QRO amplifier will help a lot if you intend to work only 
CW or SSB (not common on 2M but  used on 432 & up).
 
If you are interested in the digital modes (WSJT, etc.) then you can get 
away with 200 to 500 watts of CLEAN output.
 
The most important item is the preamp and coax/relays between the 
antenna(s) and the preamp.  Losses here are not recoverable and, as the 
saying goes, if you can't hear them, you can't work them.
 
The antenna(s) do not have to be very high above ground and closet to 
ground will get you a considerable amount of "ground gain".
 
There are many good reference books and articles that a search on the I-NET 
will find.  Much of the enhancement to making an EME contact comes from 
good operating practice so read as much as you can.
 
EME is as far from plug-n-play as you can get but the reward is that not to 
many hams can make 500,000 mile QSOs any time they get on.
 
Good Luck & Good DX,

Somewhere, on one of the partitions on one of the drives visible to one of the

IF I remember correctly (guaranty does not cover memory), an Altera AE found it

If anyone wants to try it contact me directly and I will look for it.

Re: [Flexradio] ebay 10MHz-OCXO-

Bob

FWIW, I have found in designing stuff like this over the years, that for
customer satisfaction (utility, aerospace, commercial., mil, consumer) go
one order magnitude better than final specs require ( 10 orders for mil).

So if better than +/- 1 Hz is required, design the SYSTEM(s) for better than
+/- 0.1 Hz, guarranty +/- 1 Hz and there can be no quibling over accuracy
down the road.

Your PC probably did an 'automatic' download of one of Wiley Gates' fixes for
the last 'fix' that was supposed to 'fix' the last ......to fix a "security
problem in Win xx".

Did that two weeks ago and the PC and SDR1000 have been off the air since.

Re: [Flexradio] Preview 8 DirectX

[Philip M. Lanese]

With the ATI FireGL X128 this occurs when I drop the hardware acceleration down
three notches.

With SDRConsole beta Preview 8 running, GDI+ selected, I move slider three
notches to:

"Disable all DirectDraw and Direct3D accelerators, as well as all cursor and
advanced drawing accelerators."  "Use this setting to correct severe problems
with DirectX and accelerated applications."

If I switch from GDI+ to DirectX, all functions work but the noise floor 'grass'
is no longer refreshed and moving the setup pane around the desktop erases to
black the entire display area of the console, grids, left over noise floor
grass, etc. but the little red cursor controlled display numerics still work and
follow mouse as normal (frequency, amplitude, etc.).

Attempting to shut down and restart P8 results in "Fatal Error" about 1/2 way
thru initialization with the following JIT info:

Object reference not set to an instance of an object.
  at PowerSDR.Display.Init(t)
  at PowerSDR.Console.InitConsole( )
  at PowerSDR.Console .. ctor(String[ ] args)
  at PowerSDR.Console.Main(String[ ]args)


Otherwise, CPU = 3.06G P4, 1G 400 MHz DDR, gets the following mileage:
Beta P4:  10 to 15%,
Beta P8, GDI+: 5 to 18%,
Beta P8, DirectX: 2 to 10%  (only cursor controlled display numerics active)
No SDR program running: 0 to 2%, mostly 0%

Excellent tip.

Downloaded the latest ATI drivers for my FireGL X1-128,  uninstalled the old
drivers (ugh forgot what a crummy display BASIC windows video drivers produce),
cold boot & W2k FOUND new video device, hit cancel, ran ATI setup & !voila!
display is good in P8 with DirectX now.

There is some flickering of the vertical & horizontal lines when you move the

Re: [Flexradio] A question on Frequency stability vs. Temperature

[Philip M. Lanese]

Tim, Eric2, et al
 
You can enclose the oscillator can within a thick block of 
material that has high thermal resistance (high thermal 
inertia).  You do not want to have air moving around the 
oscillator because the heat conducted away from the oscillator will 
vary as the air flow varies and that effect will make the problem 
worse.  This technique assumes you can safely heat the crystal to a 
good margin above any maximum ambient.  In order to heat the crystal, 
you need to know the CRYSTAL turn-over temperature, a 
specification not usually available for 'canned' oscillators, or you could end 
up frying the oscillator that is also inside the can or over 
stressing the crystal itself, in which case it will go 
PERMANENTLY off frequency and ready for the round file.  Most likely 
when you are about to make that once-in-a-lifetime DX contact.
 
You may reduce drift somewhat but the whole question of frequency stability 
and accuracy is: does anything you do matter if the various other ends of the 
communications circuit are not at least as stable as your 
end AND there are no variations due to propagation effects of the 
signals.  Take EME at and above 432 MHz as an example.  No matter how 
accurate and stable your frequency or that of your QSO partner, you still have 
to use your RIT to chase the returning echoes because of changing Doppler 
shift.  WSJT's EME mode 65C is no longer used much, if at 
all, because it depends on the INCOMING signal, as well as your receiver, 
being stable within 5 to 8 Hz or so over an entire EME receive 
period.  Really serious EME operators use Linrad because they can SEE the 
incoming signals' drift in 'real time' and can use the RIT when necessary 
to manually correct for frequency change.
 
You also have to remember that canned oscillators are 'consumer' products 
and the manufacturer can only invest so much in frequency 
stability, accuracy, reduced phase noise, etc. before he prices the 
product out of the market.
 
Any quickie after-market adjustment would at best be a 'one-off' and what 
are the chances of replicating a one-off 'fix' many times over.
 
If you want extreme accuracy, you have to start from scratch and go 
thru the whole (non trivial, not inexpensive and definitely time 
consuming) design process.  That's just for the oscillator.  Then you 
have to design temperature stable buffer circuits to insert between the 
oscillator and the load to effectively isolate the load, as well as 
other problem sources, voltage regulator noise, RF, etc., so the oscillator is 
not affected.
 
Then, as Jim, W6RMK, and others have pointed out, you turn your 
attention to 'fixing' the PC oscillator, the sound card oscillator, the OS 
software and the application software as needed.

[Flexradio] RFE BOARD QUESTION

[Philip M. Lanese]

How do I set 'XVEN' signal to logic '1' (+5v) to energize relay K12 on the RFE
board.  I have tried checking  "XVTR Present" (the logical choice) on the
SETUP/Hardware Config panel, then also tried selecting VHF, 2M and setting VFO A
to 144.2.

XVTr panel settings are good since I was able to run the SDR with my HB
transverter before installing  the RFE board.

Also tried selecting Positive, Negative and NO TR logic settings.

Phil, K3IB

Re: [Flexradio] RFE BOARD QUESTION

[Philip M. Lanese]

Thanks for the response Eric.

I would think that it should be (XVTR Enabled && VHF Selected) since K12 needs
to be operated in BOTH receive and transmit in order to provide a signal path
between LPFR of the lowpass filter bank and the input/output of the 2M
transverter when one of the bands above 6M is selected for operation as opposed
to selecting operation on LF to 6M.

XVRX on the other hand, would need to follow the logic rule you gave to allow
switching out the DEMI Rx circuit on transmit.

Also, I sent you a list of Fatal Error messages I am getting on all start-ups of
Preview 12 after the first but the e-mail was refused by the flex server.

I am going off of memory here, but I believe the XVEN signal goes high
whenever the 1&2 or 1&3 of the following is true:

1. XVTR Enabled/Present is checked.
2. Positive logic is selected and you are in TX.
3. Negative logic is selected and you are in RX.

Re: [Flexradio] FCC equipment authorization

[Philip M. Lanese]

Gerald & Jim

The SDR-1000 may require certification as a Part 15 Class B unintentional
radiator because of it's connection to computing equipment, its use in home
environments, the transfer of digital control data back and forth between a
computer and devices within the SDR that the FCC may interpret as digital and/or
auxiliary computing equipment.

"
FCC Part 15 Subpart B is for unintentional radiators. The category of
unintentional radiators includes a wide variety of devices that contain clocks
or oscillators and logic circuitry but that do not deliberately generate radio
frequencies emissions. Among the common unintentional radiators are personal
computers, peripherals, receivers, radios, TV sets, and cable TV home terminals.
FCC Part 15 Section 15.101 has a very informative table for unintentional
radiators. Two levels of radiation and conducted emissions limits for
unintentional radiators are specified in FCC Part 15 Subpart B. The two levels
are Class A digital devices, the higher less strict limits, and Class B digital
devices, the lower more strict limits. Manufacturers are encouraged to meet the
Class B digital device limits.
"

The TCB (Telecommunications Certification Board) personnel I spoke with today
recommended very careful reading and interpretation of the Part 15 regulations
(and cross references) as applied to digital devices.

Re: [Flexradio] FATAL ERROR STARTING PREVIEW 12

[Philip M. Lanese]

Gerald, Eric

I tried removing, downloading and installing Preview 12 again yesterday.  After
shutting down the computer and restarting, I was again presented with the fatal
error and messages I e-mailed you when start-up reached "Loading Main Form".

I then renamed 'command_memory.txt' and 'PowerSDR.mdb' and restarted Preview 12
which brought up the wizard.

In wizard, I imported PowerSDR.mdb from the Preview 8 folder and Preview 12 ran
OK.  Shut down and re-started the computer then started Preview 12 and it came
back OK without the fatal error I had been getting when start-up reached
"Loading Main Form".

All of the settings I had in Preview 8 were imported OK and Preview 12 runs with
no problem every time I start up.

Until this version, all I had to do was copy 'command_memory.txt' and
'PowerSDR.mdb' from the folder containing the previously working version into
the folder where the new version was installed, start-up and run the new
version.

Re: [Flexradio] FCC equipment authorization

[Philip M. Lanese]

Gerald, Jim
 
The TCB personnel seemed to agree that the "Intentional Radiator" part of 
the SDR 1000 would be covered by Part 97.
 
There was concern that "Unintentional Radiations" could cause 
problems, which is probably why IcoKenYaeTec have their equipment Part 15 
certified when digital communication to/from external equipment is 
provided.
 
All of this stuff is subject to individual interpretation and Jim pretty 
much summed it up with:
 
"Realistically, it's probably in the category of: as long as nobody 
complains...".
 
The problem for Original Equipment Manufacturers is that a 
complaint can cost them a LOT in consequential damage so 
most build Unintentional Radiation Compliance 
Certification into all new product design cycles.
 
I am presently involved with a new product 
that has both Intentional and Unintentional Radiations 
(RFID, BlueTooth, WIFI and GPS systems embedded into a 
hand-held WindowsCE computer with RS-232, RS-485, Fast Ethernet, USB and 
Fiber Optic connectivity options) so we have to satisfy the 
limits of radiated AND conducted emissions for BOTH.  Jim is 
right on with his caution about FO driver PC board circuit layout.
 
In fact, given a set of smaller SDR boards and conversion of 
the PowerSDR GUI to run under Real Time Linux, this 
product could be used for a hand-held SDR1000 with a built-in 
wired, wireless and/or fiber internet connection.
 
With new off-the-shelf, direct conversion ISM 
Band Systems-On-a-Chip, this product has reached the stage 
of development where it can be 'software 
re-defined' for CW/AM/SSB/FM operation in the 14, 432-450 
and 2304 MHz bands which are very close to nearby ISM bands (i.e. 
13.56 MHz ISM to 14 MHz HAM).

Re: [Flexradio] FCC equipment authorization

[Philip M. Lanese]

I remember talking to you last May about using SDR concepts in this area.  I
have since built a prototype radio for the 120 kHz ISM band using a $10
off-the-shelf IC, a $12 APEX TO-220 case audio amplifier and a small loop
antenna to identify, count and track pigs, cows, pets & people stealing
merchandise.

Tune up 40 kHz, make a really BIG loop antenna, add some DSP and you have a
hand-held 160 kHz LOWFER radio.

Re: [Flexradio] DUBUS article on ALC]

[Philip M. Lanese]

Bob
I did some vhf long haul dx testing (300-400 mi.) and found that my voice needs 
the finer shaping capability of the 15 band equalizer to really be heard well.  
When I got it 'right' the comment was "outstanding clarity".

On Rx, I also find I can 'tweak' the 15 band equalizer to get more improved S/N 
on weak VHF signals with my 'Half Century Club' hearing.

Maybe a choice between 3 equalizer bands for those with excellent hearing who 
don't like to fiddle and 15 bands for me and my younger cousin Methuselah?

Re: [Flexradio] Linux for Windows Boxes (was Howcum?)

[Philip M. Lanese]

 I have had very good results using System Commander to multi-boot for many
years on several different computers with various combinations of MS DOS 6.22,
DR DOS, NT, 95, 98, 2000, XP, WARP, Red Hat, Fedora, SUSE or KNOPPIX on CD OS's
installed and selectable at boot time.  The advantage is that no OS can destroy
the MBR and make the disk unrecoverable because the original is saved and
reinstalled when System Commander runs after the bios boots.

Each OS is completely isolated from the others unless I allow it to "see"
another OS in System Commander.  The Linux systems can easily see Windows or
other OS's partitions, folders or files by simply editing the boot file to
"mount" the partitions, folders or files you want available.

This lets me boot back and forth between windoz and linux and have complete
access to the same file(s).

You do need to install the OS particular drivers for sound and video cards as
each OS boots so the boards work the same (i.e. Linux drivers for ATI and
Delta44 in Linux and Windows drivers for ATI and Delta44 in Windows).  You have
to contact the video and sound board manufacturers to get the correct drivers as
the generic types supplied by the OS distributor may not be current for the
particular boards you have installed.  This is especially true for high end
boards like the ATI FireGL's and Delta44's.

I remember seeing a post on the moon-net or vhf reflectors about this problem
WAY back and someone posted that there is a way to kill the "probing" by

Bob's explanation is very good, but I think Paul has a real problem.

At a 96 KHz sample rate the signal should *not* disappear at about 15KHz to
the right of the center-line as Paul tunes down and the signal moves to the
right.  In fact, you shouldn't see this phenomena with the +/- 20 Khz
display running the new code at 96 ksps.  The signal actually disappears at
roughly +37 KHz from the center-line (i.e. 48 KHz from the IF), which is
beyond the +20 KHz display boundary.

>From the description, it sounds as though something in Paul's system is
remaining at the 48 KHz sample rate when he sets the system to 96 KHz.
Perhaps it's his soundcard?

Or maybe I missed something - does the new code allow you to display a +/-
20KHz window when running at a 48 KHz sample rate?

Paul:

Thanks for asking.  I know it is confusing.  It is why I resisted adding
the wider scope for so long.  People often do not realize the
consequences of their requests and this is one of them.  It is NOT a bug.

The signals as they arrive from the radio  are below, at, and above the
local oscillator frequency:



BBXIA

B is below, X is at, and A is above the local oscillator.  We have a
special point above. It is called I.

I is OUR last IF.  We put it there because in a lot of sound cards,  you
can see junk at X because of DC, hum, ground loops, 1/f noise, etc.

Our last IF is at 11025 Hz for historical reasons.  It probably could be
lower with the D44, etc.

When we demodulate,  we spin this spectrum to the LEFT and do it
circularly so after we are done it looks like this:

BXIAB

I is just below, at, or just above 0 frequency after we do the
"spinning".  We apply the upper sideband,  lower sideband or real
bandpass filter here depending on the mode.

We wrap it around the left, but we MUST take those that fall off the
left and push them down on the top on the right.  There is no escape
from this mathematical fact.  There is nothing we can do about it.  It
is the reality of our system.  I suppose we should put in a mode that
has the "green box" for the filter in the right hand side of the SPEC
screen and then does full width asymmetric display.  We will need to do
this to enable N watch receivers on the passband anyway for click tuning
anyway.

MUCHO THANKS Bob

A few words does wonders to replace Microskunk's non-existent documentation.

Had wrong version of DirectX-SDK and almost repeated but while it was
downloading I smurfed the site & found a version of DirectX9SDK for W2K (October
2004 I think it was).  Downloaded it & it installed to c:/Program Files...
and VS2003 works correctly now (except for heartstopping switch to BLACK screen
during compile).

Build log was saved at "file://d:\Power sdr project
trunk\temp\Release\BuildLog.htm"

fftw_wisdom - 0 error(s), 0 warning(s)



-- Done --

Rebuild All: 6 succeeded, 0 failed, 0 skipped

Re: [Flexradio] HOW TO?

[Philip M. Lanese]

"HOME BREWED" PowerSDR 1.6.0 running fine from ...\bin\release with .mdb
imported from Preview 19!!!

Thanks again Bob

Re: [Flexradio] fftw_wisdom.exe

[Philip M. Lanese]

Lee
It is placed in the Program Files folder when you install PowerSDRxxx
Run the file and it will create a new file "wisdom" (no extension).  Don't jump
when the screen goes black, it's normal.

Re: [Flexradio] 6 meters recieve on 5000

[Philip M. Lanese]

Also -- Everyone who gets seriously interested in weak signal VHF/UHF operation
quickly learns that the ONLY place to put a pre-amp, tailored for each band of
interest, is as close to the antenna as humanly possible (usually in an
enclosure close to the top of the tower).

This allows SHORT runs of *expensive*, LOW loss cable between the antenna and
the pre-amp and lower cost, more lossy, runs of cable between the pre-amp and
the receiver/transverter in use.

No manufacturer can build the kind of performance gain that is provided by this
simple "add-on" into a production radio.  PHYSICS rules the game.

Re: [Flexradio] PreSonus FIREBOX firmware fix

[Philip M. Lanese]

Jeff

Just downloaded your "New Console" and it runs fine with PowerSDR v1.6.0 as well
as the SVN TRUNK version I compiled and have been using since 3/28/06.  The only
"Exception" was:

Just-In-Time Debugging
An exception 'System.Argument Out of Range Exception' has occurred in
PowerSDR.exe

when I attempted to set the panadapter display to 'Phase2' in either program.

My "home brewed" SVN TRUNK SDRConsole restarted fine but the 'official' PowerSDR
v1.6.0 produces
a "Fatal Error" when I try to restart it.

Re: [Flexradio] SDR keyer port code location

[Philip M. Lanese]

Chris
I did what you surmised when I connected my Bencher paddle key.  In my case=
, I separated the diode OR and pull-down resistor from the dot and dash key=
 line inverters and fed one of the diodes with the line from my external se=
quencer (ground for PTT) thru a spare inverter in IC4 to generate the corre=
ct logic.  Also check the value of the pull-down resistor (R9).  It should =
be 1000 ohms or less to properly load the parallel port line.  I wound up w=
ith 470 ohms but the proper value should be installed in production units n=
ow.

The key line(s) should also be routed thru either hardware or (preferred) s=
oftware AND gates controlled by the PTT line, to avoid unexpected switches =
of SDRConsole to transmit if the keyer line grounds since there is some oth=
er place in the software (probably for QSK) where any activity on either th=
e dot or the dash parallel port lines also switches SDRConsole to transmit,=
 independent of the state of the diode connected PTT parallel port line.

My solution has worked fine for the past few years up to ~ 30 WPM (at faste=
r speeds, the signal begins to merge with the noise on long VHF/UHF paths a=
nd is more difficult to copy).

So Bob, howcum ur not on 2M where you can immediately hear the results of your

to the XYL.

WA2UMX/B (20W to 2 Big Wheels @ 316 mi.) is 10 to 20 dB > noise floor (-150 dBm

Re: [Flexradio] [OT] Danger! Ubuntu 6.06 beta busted MBR/partition size

[Philip M. Lanese]

Ken
After the last experience with SUSE 10.0 I now use Partition Magic to clone copy
drive 0 to drive 1 (backup), then play.

The two floppy disk set generated by PQ Magic will allow you to run PQM under DR
DOS from floppy at boot and then you simply copy drive 1 back over drive 0.
Easy (if time consuming) restore, but READ DOCS first.
