Re: [Flexradio] Frequency stability

[Guy Atkins]

This site, which 
I've had bookmarked for a long time, offers low-priced 10 Mhz frequency 
standards for homebrewers:
 
http://www.aade.com/
 
AADE offers nice 
little digital frequency displays, too, for old-tech radios.
 
The firm is just a 
few miles from me, but I don't know if it's an actual storefront or a cottage 
industry run out of an amateur operator's home.

Re: [Flexradio] RFC - Poor Man's Universal Controller Board

[ltaft]

E^2,

I'll give it a runthrough and see what should be on a "little" board to isolate 
the big bad world from the delicate innards of the ULN 2003.  

What I did for X2-7 was put a diode cross the relay coil in my Drake L-4 amp as 
that coil puts out over 400 V on the back voltage.  The coil is driven by a 30 
VDC supply and draws 50 MA when the transmit line is grounded.

What else do people have in amps?  Control line specs?

I know there are already several widgit boxes on the market for the amp control 
interface.  We need to have the rest of the input/outputs protected and 
incorporate the amp control in one plugin.

Title: Elimination of popping w/ VAC & MixW on TX



Update.  After testing for what I thought was a 
satisfactory period of time, I found that the int settings of 50-60 ms do 
somewhat better.  I had several transmissions with no popping and then one 
showed up.  I change the int value to 50 and it seemed to get 
better.

[Flexradio] RFC - Poor Man's Universal Controller Board

[ecellison]

Folks

 

I think I blew the ULN 2003 open collector chip out of my
radio during the Belize DXpedition by trying to connect a relay in an amplifier
directly into the radio on x2-7 without any buffering. Perhaps a spike or
surge. Dunno. But it brings back to mind a project I suggested to Tony –
KB9YIG who has done a fantastic job designing and refining kits for the
SDR-1000 and is currently totally immersed in the SoftRock40 SDR.

 

At one time I had suggested a “Poor Man’s UCB”
to connect dedicated and open pins to the X2 15 pin connector. It was shelved
and deemed not necessary since users can plug just about anything into the X2
connector and experiment.

 

As a result of my experience, I’d like to ‘throw’
out an idea to create an inexpensive PC Board to protect the X2-7 output to
control Amps etc, with a 5 v relay and provide jack for  a cold switch to
ground for X2-10 PTT input. X2- pins 1 thru 6 could be brought out on a 6 or 10
pin Berg connector for readily available ribbon cables to interface the control
lines to some external device, like a universal controller board or for
experimentation by users in a breadboard. Having a little external board
connected to the X2 connector perhaps with opto isolators would be a lot
cheaper than replacing the ULN – 2003!

 

Anyone like to comment or tackle the design or parts for
this board? Let’s kick it around a little!

Re: [Flexradio] Teamspeak Forum Audio - 11-19-05

Jeff

 

Well, I know that Phil N8VB is working
with an Altera and from his previous post has a Xylo board. Phil – VK6APH
has also purchased a Xylo board as have I. My knowledge is minimal however, the
board was inexpensive and it would appear that this kit and the sample and
supporting C and HDL code would form the basis for a great ‘glue’
chip for many projects which we have collectively discussed for the SDR-1000
over the past year. Phil is designing an entire SDR based on FPGA.

 

Early this year, we had 3 users interested
in a PIC-4550 with USB, and we all bought boards, C-compilers, and protokits.
but that project is stalled, for a number of reasons, none the least of which
was a pretty buggy C compiler IDE from FED. Also streaming audio back through
the USB port was a bit too slow in serial. A lack of good understanding of
audio USB interface. Etc.

 

I think the primary excitement last
February was the prospect of eliminating the need for a sound card. We did some
research and rejected almost all Codec chips at the time, and found the very
inexpensive  Wolfson 8785 ADC chip which has an I2S interface, for minimal
parts and connections, 192, khz, 24 bit, stereo input, thd 102 SNR 111

 

http://www.wolfsonmicro.com/uploads/documents/WM8785.pdf

 

They also have a nice DAC chip in the same
type mold.

 

At the same time and after,  we have
discussed a number of other projects which would be ideal  to nail into an
embedded system.

 

High accuracy/stability time base using a
1 pps time source from GPS receiver.

Integrated full function Keyer with
sidetone.

DDS replacement PLL or NCO.

TCP/IP for remoting of the SDR-1000

Replacing the switch functions on the PIO
board over USB rather than parallel port.

External Main tuning knob(s) and other
handy buttons for the folks who quiver and shake in “Knob Withdrawl!

Complete replacement of the PIO board. 

 

I am sure I am forgetting things we
discussed as potential for embedded system ‘assist’ for the SDR
1000, and haven’t thought of others.

 

I think a project like this needs both
folks (as many as we can get) who have experience with this embedded system,
taking the lead, or suggesting resources methodology and code. Then others
willing to support and test code etc.

 

Thanks for speaking up! This is worthy of
discussion.

 

Eric – AA4SW

Sorry have been falling down on the job! I will post last
two weeks forum audio after tonights audio. Came back from Belize thinking I was still on
vacation (smile). Actually with broken radio and broken computer. The computer
has all my tools for doing just about everything. Got a bit Crushed in
it’s Aria enclosure, on its way back from Belize and now has an intermittent,
sudden shutdown problem!

 

In any case have fallen back to a laptop and installed the
audio stuff I use for teamspeak.

 

Tonights audio:

 

Phil departing for South
  Australia (wherever that is! I thought he WAS in South Australia!!)….
Winked and blinked his green light, since he had to go. He has been working
with the Xylo Altera FPGA board, and has gotten it interfaced with the Wolfson
AD chip and configured. Next week he will be working on streaming stuff from
the chip back through USB to the computer. Since he mentioned this project last
week on the Teamspeak forum I have practically spent every spare minute reading
about it. A perfect building block for the SDR, and many other things and CHEAP
in this experimental implementation! He is asking that anyone with Altera
– FPGA – HDL experience join up with (now us since I just ordered
one)! Anyone with FPGA experience? This is it! If not just join in and learn. 

 

Bob K5KDN has completely reworked the CAT command interface
class structure he originally wrote. He will be adding additional CAT commands
to the SDR for the new features which have been added.

 

Many other great conversations and some discussions about
debug of the VAC.

 

Will post previous weeks audio tomorrow.

Re: [Flexradio] Could this be a protocol problem?

[Bob Tracy]

I looked at the latest code (Preview 7) and didn't see any changes to that
section that would affect CWU and CWL. I cranked up DXLab Commander (free)
and HRD (free), both worked just fine with the SDR CAT emulation set to
either Kenwood or SDR1K.

Sorry, I don't have a copy of N3FJP, I did use a trial copy (successfully)
when originally developing the CAT code but the trial period expired.

When I click on CW_U the logging program correctly changes to CW.  But when

Could SDR be sending a command from CW-L that could be interpreted as SSB?

Selected unsupported card since my usual MP3+ is not connected.

Audio Driver:  Selected Windows WDM-KS
Selected Realtek AC97 Audio (motherboard audio) for input, output, mixer
Apply, close, Turn on, play file, within a few seconds get Dr. Watson

Closing the dialog results in instant reboot, no BSOD screen, no dumps.  
Repeatable.


Windows XP SP2
Shuttle FB-52G2 2.66GHz P4
RealTek AC97 motherboard audio

Probably an illegal selection combination, but it was there and I tried it 
:-)


I tried using the Audigy 2 ZS for the input/output/mixer (still have 
unsupported card selected) and notiifcation pops up with unsupported format 
and no problem there, I select something else.


FYI.  Did a ham radio club demo this week, many interested, lots of good 
questions.  This might be a bit expected since it was the Microsoft Ham 
Radio club meeting.  Just a few programming types in there :-).


For the demo I ran the program in demo mode and with the SDR connected.   
Played back wav files.  Ran on a Toshiba Potege M200 1.7G Pentium M, 7200RPM 
drive.  Used the MP3+ and USB adapter.   This combination seems solid and 
was easy to get running.  Used ASIO 2.6 and Preview 5.

Hi Eric,

The Xylo board is pretty neat.  I have one that I use for trying out
new ideas for the HPSDR.  The downside is that the schematics for the
board is not available and the source code for the FX2 firmware and
driver is not available either.

This is the connection from the FX2 to the FPGA on the Xylo:

FPGA_PIN 10 = FX2_CLK
FPGA_PIN 54 = FX2_FD[0]
FPGA_PIN 55 = FX2_FD[1]
FPGA_PIN 56 = FX2_FD[2]
FPGA_PIN 57 = FX2_FD[3]
FPGA_PIN 49 = FX2_FD[4]
FPGA_PIN 48 = FX2_FD[5]
FPGA_PIN 47 = FX2_FD[6]
FPGA_PIN 42 = FX2_FD[7]
FPGA_PIN 41 = FX2_flags[0]
FPGA_PIN 40 = FX2_flags[1]
FPGA_PIN 39 = FX2_flags[2]
FPGA_PIN 38 = FX2_PA[0]
FPGA_PIN 37 = FX2_PA[1]
FPGA_PIN 36 = FX2_PA[2]
FPGA_PIN 35 = FX2_PA[3]
FPGA_PIN 29 = FX2_PA[4]
FPGA_PIN 28 = FX2_PA[5]
FPGA_PIN 27 = FX2_PA[6]
FPGA_PIN 26 = FX2_PA[7]
FPGA_PIN 50 = FX2_SLRD
FPGA_PIN 53 = FX2_SLWR

I am working on a schematic for it also.

Thanks for the forum audio.  For those of us who are not around on
Friday night it is great to be able to play it later.

Title: While I am on a roll with Preview 7



Thanks for the info, but I don't think that is my 
problem.  I am using an AMD Athlon dual core 4400+ with a gig of RAM.  
With MixW, SDR, Firefox and e-mail open, I am using less that 10% of the 
CPU.
 
I 
closed everything but MixW VAC and PowerSDR and I still get the pops.  I am 
beginning to suspect VAC.  I loaded it (licensed copy) last night and that 
is when I really started noticing it.
 
I 
still have some more experimenting to do

Tim,
 
I am not sure if it is relevent but the problem 
sounds similar to one experienced by Dave W9AD. His problem turned out to be an 
underpowered CPU. He was using the AM and SSB modes and the utilization was 
quite high (30 to 40% on receive). The symptom was identical to your 
description.

  I am noticing a lot of "popping" noises in the 
  received audio in both digiU and USB mode.  I checked this out with 
  another receiver and the pops are not heard on it.
  I tried changing buffer settings but nothing seems 
  to eliminate the random popping.  Over a 1 minute period, I hear anywhere 
  from 5-20 pops.  I can see this on the MixW screen too.
  Changing the buffer sizes does not seem to make a 
  difference, with the exception of the many IRQ_Not_Less_or_Equal blue screens

  different orders.  I have the mini dumps if anybody wants 
them.

I have seen the BSD's but I have been having other flakes.  So, this is 
related to VAC?  Please let Eric have the dumps.   There have been some 
changes in the C# code in the callback and I did not see these BSD's 
until recently (though I was running VAC before) so it looks like 
something may have gotten hosed.


The problem with VAC is if we find the problem is in VAC,  we are stuck 
unless someone wants to pony up the $5000 the guy wants for his source 
code ;-).

Bob,

If I am not mistaken, when I select digiU mode, shouldn't the CAT tell MixW
to go into USB mode?  There are a lot of ASFK modes that are not PSK so
forcing digiU to put the digital mode program into PSK is a real restrictive
condition.


The USB CAT command is supported by MixW because I can select USB in MixW
and it puts the SDR1K into USB mode.

That's due to the CAT code not being current with the updated console
controls, the old button legends were RTTY and PSK.  However, even when the
code is updated, you will not get a correct mode indication in MixW since
you are using the Kenwood emulation and the only digital mode choice in the
Kenwood MD command set is RTTY.

I checked HRD this morning and it shows PSK for DigiU and RTTY for DigiL.
The fix for MixW (and all other third party software vendors except HRD) is
for them to support the SDR-1000 command set in their code.

So, you're seeing a shift of 60/15E6 or about 4ppm?
What kind of sound card are you using?
The oscillator on the SDR1000 is in that ballpark stability wise, but a
more likely source is the clock on your soundcard.  My experience
has been that the stability of the sample rate on the sound card is on
the order of a few parts per thousand.  That is, 60 Hz out of 40 kHz
sample rate is in the ballpark.
Particularly if your computer has a varying load, the temperature inside
the box can vary significantly as the CPU and disk drive dissipate more
or less heat.
One way to figure out which it is is to look at the carrier AND at the
audio tone on WWV.  If the sample rate on the sound card is wrong,
then the spacing of the tone from the carrier will be wrong.  If the
SDR1000 is wrong, and the sound card right, the spacing will be right on,
but both carrier and sidebands will be shifted.
In reality, there will be errors in both, and a bit of algebra can tell
you both.

The tone is 500 Hz, 600Hz, or 440Hz, depending on which minute of the
hour it is.  The tones are generated by dividing down the same
Cesium references that generate the carrier, so they are quite
accurate.
You might also be able to use the 100 Hz subcarrier, but that's pretty
close to the carrier.

Re: [Flexradio] VAC issues with Preview 7

[Tim Ellison]

In digiU mode, using the predefined filters, the rx and tx filter stays to
the USB (right) side of the panadapter display.  If you select the Var1
(default=Res) filter it is displayed on the LSB (left) side of the
panadapter display.  The width and shift seem to behave in a really screwy
way.  I can play with it by making it real narrow and can get it to shift to
the USB side, but only by ~500 Hz.  Most of the time the filter splits or is
on the LSB side of the panadapter display.

The Var2 filter in digiU mode show some what of the same behavior.

I would expect the var1 & var2 filters to occupy only the USB side of the
carrier point in digiU mode and the LSB side of the carrier point in digiL
mode.  Am I correct in my assumption?

Hi Tim.  Do you mean  you think the filters are correct?

When in DigU, Both the rx and tx should be on the USB side of the
displaySame with DIGL, but they are not.  At least not here.

Here is what I wrote:

I have the popping or clicking noise using MIXW and the purchased version of
VAC.  I was able to reduce the popping (sometimes it is there, sometime not)
on PSK31 by setting the audio processing setting in the soundcard setup
screen to Message-based (standard) rather than Direct X and setting the VAC
buffers to 512.  All of the other buffers are 2048 using a Delta 44.

CAT in MixW says I am in FSK mode.

Setting VAC buffers to a value higher than 512 make things much worse.

It works, I just had a bpsk31 QSO with YV5DSL.

This is useful information.  DirectX for audio sucks.  I have had mine 
set to message based since the beginning and just forgot this in my 
setup note.
