Hi Mike,

Usually they were centered around 7.056MHz.

Take a look at the crystal fitted and divide by 4 to give the centre frequency.
In that oscillator configuration, they usually run a little on the low side, but
you can calibrate it afterwards.

I was running psdr_iq 1.12.07 just fine with my Firewire Solo I/F but after
loading psdr 1.12.20 I just get continous beeping and no signal in the spectrum
display. I can't find the 1.12.07 code to reload either.
Can anyone shed any light on this problem or point me to the 1.12.07 code so I

I have the SoftRock 6.3 for 40M and would like to operate that in the Linux
environment.  I have FLDigi, Hamlib, SDR-Shell and many other ham radio
applications running in Angstrom Linux on the Beagleboard (www.beagleboard.org).
FLDigi seems to be much faster and less "buggy" than when I run it in Ubuntu on
my PC.

However, I have not yet gotten the 6.3 to work with FLDigi (only Rocky) and
wondered what settings to use for the the Si570/USB. Also is there any setup
required for the atTiny chip on the USB adapter? Has anyone else worked with
FLDigi on the 6.3?

As a side note I have been able to operate my Small Wonder Labs PSK20 with
FLDigi on the Beagleboard and made 5 contacts the day before Field Day this
year. One was from here in Richmond, VA to Warner Robbins, GA - 615 mils away on
about 1.5 watts on BPKS-31. For that I used a USB/Serial adapter for PTT to the
rig. If that info will help me with the 6.3. I do have Tony's Si570/USB setup
for that.

Thanks and 73

Thanks Fred(!) for the fix...

I'll save the group a jump by echoing the change from Fred's page:

http://home.ict.nl/~fredkrom/pe0fko/SR-V9-Si570/

Version 15.11:

Bug fix with negative frequency offset value. Using a negative offset value in
the LO calculation will not add / subtract anything, in the previous firmware
version.

The bug is fixed, and the code still fit in a ATtiny45 chip (2 bytes free) also
the ATtiny85 version is available.

A other small change is made to the band crossover point values. The previous
version did store the si570 running frequency, the new version will store the
set frequency. In the default case of offset=0 and multiply=1 there is no
change. And also the command 0x3A will return the set frequency and not the
Si570 running frequency.
The change is completely handled by the configuration tool ExtIO_Si570 version
0.9, use that or newer versions for this firmware version.

I put together a V9.0 recently, and have been developing a QUISK
extension.  I jump around the bands, from 0.88 MHz to above 33 MHz.  I
seldom spend time on 10 meters because it seemed to have excessive
noise.  Then the other day I switched to 10, and the tuning happened to
be on the center (LO) frequency, with USB demodulation.  Hey, I could
understand the noise.  It looked like an AM signal, but AM modulation
was not understandable, perhaps because the carrier was being killed by
being at zero Hertz audio.  I listened to the station.  It turned out to
  be WIBA (1310 KHz).  Its there when my LO is set in the range 25 MHz to
  33+ MHz.  I have no idea how this can happen, or why WIBA is so
special.    (Another local station at 970 KHx shows up at 1940 in the
160 meter band, but that is understandable.)  I just tried again running
  Rocky under XP.  Same thing, so it is probably something in my
hardware.

Do you have any idea what is happening or how to fix my V9.0?  Tnx in
advance.

    Don

Hi Don,

The AM MW broadcast image problem at the top of 160m, above 1.90MHz is common
with the v9.0 RX, and I do see it here on my two.

The other problem between 25 and 33MHz is much more strange. If it always
happens exactly at the zero point and at any different LO frequency, then it
surely cannot be any mixing or image problems, as it would more around as you
change the LO.

How close are you to that particular AM broadcast station, and how strong is the
signal you are seeing on the SoftRock?

I wonder if you have a problem with direct pick-up on your soundcard leads, or
even inside the PC itself?

Maybe the problem is present all the time, but at the higher frequencies, the
band noise is lower, so it starts to show up?

You could try running the SDR programs without the v9.0 soundcard leads
connected at the RX end, but still plugged into the soundcard and see if it is
still present, if it is, its not the SoftRock to blame (you will need to keep
the USB lead connected to stop any error).

It its pick up on the leads, try the usual ferrite beads or clip on chokes etc
to remove it.

I guess if it is pick-up, it will be common to both the I & Q signals, so one
would be shifted 90 degrees in the SDR program, not sure what it would sound
like.

Good luck,

73, Bob G8VOI

I would like to synchronize the frequency of softrock v9 with the TS-2000 Across
the CAT powersrd iq of 1.20 (sv1eia)
I tried directly from the cat powersdr that through ham radio deluxe.
The connection is made correctly for the change  frequency and only for the
band. Not  for the mode (SSB-cw etc.). Furthermore, after a few seconds  the AF
gain of powersdr goes to zero, the move to listen and immediately returns to
zero. The firmware of Softrock v9 is the 15:10
Someone can help me to configure TS-2000 with the softrock v9?
In the setup cat of the powersdr I have ID as TS-2000 and Allow Kenwood command
clicked For use to ham radio deluxe and powersdr I use N8VB VCOM
Thank you

I put together an USB-I2C kit for use with a "non softrock" project and ran into
trouble getting things to work. Using the DG8SAQ "USB_Synth" utility I got the
happy "green light" indicating that the interface was found. Everything seemed
to be responding properly but the Si-570 was putting out on default 56.32 MHz
regardless of the setting selected. Looking at the output on a scope showed the
56.32 MHz out, but rapidly moving the mouse wheel would result in a second
"phantom" display at a different frequency.
I thought I had blown the Si-570 but decided to try using another (known
working) USB-I2C interface; it worked as expected! Switching back, the bizarre
behavior returned. Back to square one, I decided to check the wiring of the
interface again and found that the SDA and SCL lines were backwards. Putting
them right solved the problem.

Pray someone tell me: How can the AVR successfully set and read-back information
to the Si-570 with the SDA an SCL lines interchanged?

Thanks for your attention.

That is all it indicates, it shows that without a Si570 connected.

I don't think it did.

Hi Rob,

FLdigi uses the hamlib for rig control and hamlib has the skeleton code
for controlling the Si570 chip, but the support is not yet implemented
as far as I know.  One option is to implement the Si570 control support
directly in hamlib and the second option is to implement the code in
FLdigi to interface with the usbsoftrock program (via UDP sockets).

Bob,
    I pulled the audio line: no more WIBA on 10 meters.  Then I put it
back and
pulled the antenna from the V9.0.  Again no more WIBA.  I just used
Travelquest
to find that I am about 6 miles from the transmitter.  It seems to me
that the
problem is in my V9.0, perhaps the BPF?

With the kit completed and the 80m PA and BPF installed, I had 82.9 mA with the
100 Ohm series resistor, and 107.8 mA without it (using 12.5V supply). Then I
continues to finish installing audio cables for I/Q, the I2C USB interface, the
antenna connector, and mounted it in my case. Then I had 85 mA with the 100 Ohm
series resistor and 116 mA without it. Probably shoulda starting troubleshooting
without power right there, but decided to check the 5V and 3.3V test points
first. They were both close. Then measuring current again, I popped the 315 mA
fuse in my multimeter. Wasn't sure if I touched something stupid, so I retried
with the 100 Ohm resistor and again got 85 mA, but again blew a fuse without the
resistor. U4 (LM7805) was warm, but not hot.

So what have I fried for sure and what might be the cause of my troubles? Tell
me what to measure and I will.

Thanks!

Hi Don,

Are you using the switched BPF module with the v9.0 RX or the manual plug-in
ones?

If you are using the switched BPF module, which version of the firmware are you
using to control the filter module?

If you are using Fred's v15.10, the 'ABPF' mode is the best one to use as it is
compatible with all of the SDR software. Check the three filter cross over
points are set to 4, 8 and 16MHz, which is their default state.

One test you could do is to disconnect the lead linking the main board J3 to the
connector on the filter module, and without any jumpers fitted to JP1 or JP2,
that will select the band 4, 16 - 30MHz BPF correctly.

I cannot really think of anything actually with the filter that could allow the
MW broadcast through, except perhaps if L11 was open circuit, but even then I
find that very unlikely.

Its the fact that you say it is always at the exact centre frequency, and not
affected if you move the LO frequency that makes be believe it is direct
pick-up, and not a result of an image or mixing process.

I suppose it could be pick up in the op-amp part of the main board, but the
capacitors C29 / C30 should cause the frequency response to roll off well before
the MW broadcast frequency.

Last comment, do you have your v9.0 in a screened metal box, or is it just
running open on the bench?

Hi Bryan,

If that is the first time you have had it connected to the USB to I2C interface,
I suspect that if you have only recently got that kit, you will need to change
the set-up the firmware in the AVR chip.

If it is a recent kit using Fred PE0FKO's v15.10 firmware, that defaults for use
with the v9.0 RX, and the line used for the PTT function is one of the switched
BPF control lines, so I suspect it might be set to a high, causing your v6.3
TX/RX to go straight to transmit, hence the higher current. You can check and
see it the PTT line is 0v or +5V when you switch on.

If it is +5v, you will need to set up the firmware.

To do this, you need to use the Winrad program, with Fred PE0FKO's supporting
dll file in the same folder. You can get it from here:

http://home.ict.nl/~fredkrom/pe0fko/ExtIO_Si570/

When you run Winrad, do the following:

Select 'Show Options' > 'Select Input' > 'Softrock v9.0 Si570'

Then press 'Start' to run Winrad

Press 'H' on keyboard to bring up the firmware set up screens and select the
'ABPF' tab. Click on the 'tick' in the 'Enable' box to remove it (not enabled)
and press 'Save'.

If you disconnect the USB lead and reconnect it, the firmware will now be in the
right state for the v6.3 TX / RX and the PTT and CW key inputs will function
correctly.

Hi,
This is a sanity check with y'all before I lift the f-flop chip (U6- 74A
C74) off the board for testing.

The voltage divider (r9 & r10) is giving trouble.  The voltage at r9-r10
is almost up to the 5-volt rail voltage.  R9 top end is 5-volts.  R10
bottom end is 0-v .   I've pulled the two resistors and verified their
values.  I've replaced the coupling (c19) capacitor that feeds the
r9-r10 junction.  I've inspected every solder joint for bridges to other
components, and scraped between them with a pick.

The mid point of the divider should be 5 volts.  However, there is that
si570 signal feeding thru the cap.  Is a dc offset of the signal pulling
up the metered voltage?  I really doubt it.

My conclusion is that the flipflop clock input is pulling the voltage up
somehow. So, I've ordered some fairchild chips (couldnt find Ti) to
replace the one I will lift for test in case the chip is the source of
the pullup.

Just thought I'd ask for the symptomatic information before I end the
life of a chip.

Have a great day!

am , and with me haveing bad eyes , i tried to solder them back on .but i think
i have dond damage to the bourd wer you solder the on .. so i am asking if any
one out there in radio land can build me just the bourd as i have the switching
bourd that shuld be working ok as all the lights still work but the main bourd
dosnt as it says usb divice not recongized en i plug it in .. i will pay for new
bourd and for making it up for me and if the old bourd is ok to you i will pass
it on to you . so if anyone can help me please as i realy miss my radio i would
