A few days ago Gary, W7FG, posted a problem to the group that he was having
with CW Skimmer. I originally have had CW Skimmer working great here with
PowerSDR, however as of late I am having issues with it to the point I am
about to throw in the Skimmer towell.
The specific problem is this:

Hi Joel
Sorry to hear about your problems ... I sold my FTDX-9000 and picked up a
Flex-5000A ... I planned to do the same as you (Flex, Skimmer, WSJT, etc)
... my problem is that I have tried to install on no less than 3 computers
here and I can't even get the Flex to install properly on any them
I thought the advances in cell phones were amazing.
Each week it seems there are new models with more functions.
(I still have a bag phone)...I'm waiting till they perfect the smaller ones.
(and I thought the 'Dick Tracy' wrist radio was pure fantasy)
But the advances in ham radio,
There is some disconnect here.
I experienced it also and can fix it...but not sure why.
The offset AT LEAST IN MY CASE occurs if I change the 'Sampling Rate' in CWS
or in PWSDRAUDIO'SAMPLE RATE'
The two settings must agree, the funny part is...I thinks it's important in
which order you set
Hi Joel
Are you using CW-L? If so I think you have to set the IF freq in
Skimmer at 6400 for it to work correctly. I was having similar
problems until Ed set me straight!

Hi Kevin
Send me a list of your problems off list and maybe I can help you thru
some of them!

Hi Neal,
No, I'm using CW-U but everything I understand about this (VERY little)
indicates this is an Audio IF issue, I just don't what is causing it or how
to correct it.
I'll try 6400 just to see what it does. I did futz around with different
audio IF settings. Of course, it did change things
OK...CW Skimmer problem solved here at W5ZN.
Ed, N5DG, just dropped me a note and said to make sure spur reduction is not
checked.
It was.
As soon as I unchecked it everything is working FB.
I don't recall seeing this in the write up on the Flex site, so whoever has
access and control to
Ed is a marvelous resource, we all owe him a great deal of appreciation!
THANKS ED!

This is pedestrian, but make sure SR is tunred off in PSDR or you will get
wacky offsets

What's most interesting is there is the holy Grail of ham receivers on the
first page...;.Dual diversity and infinite adjacent rejection. All for $4500
in equivalent money
You get all that and a whole lot more in a F5K plus second RX for 1500 bux less

Hi Joel.
I hope you are doing well.
Let me explain the SR issue a little bit. If I get something wrong, Eric will
jump in and correct me.
When you change frequency, with SR OFF, the radio hardware (DDS) is changed
every time you change frequency. With SR ON, the radio hardware is only tuned
And smarter than 99.99% of those 1/5 your age. Of all the people making
contributions to getting us going on the next generation of SDR software for
flex and others, with AMAZING things, it is Bob. He is the single most
amazing septuagenarian I know. I know an octogenarian who is probably
I'm wondering...why should the CW Skimmer/PowerSDR interaction care if
PowerSDR's SR is On or Off? It shouldn't.
I'd hope that any external program should be working with frequencies
from PowerSDR that have already compensated for the state of SR
(compensated internally within PowerSDR).
That is a bandaid, and not a real fix. Now you are forced to send high
speed retuning commands as you dial through the band. The problem is the
software offset is not being shared properly in the interop with CWSkimmer.
This is a bug, most likely in the interface program and needs to be fixed.
I can vouch for that. I was 21 in 1964, just moved to Texas, and Bob taught me
how to fix Collins S-Line radios among other things at one of the (two!) local
ham stores (Busackers) where I worked with him part time.

Ah yes!
I only agree that it is a bug-in-thinking that a variable software
oscillator in PowerSDR can be handled by interfacing directly to the sound
card device of the FLEX-5000. ;)

This was exactly my question as well. Until I realized that most people are
interfacing to the audio from the 5000 directly rather than going through
VAC or some output on the radio itself. This means that the software IF is
not being taken into account. Spur reduction adds in a variable offset
Marin,
Since I don't know what your setup is I will give you a suggested setup.
First install DDUtil (see Flex KB). Install ComoCom (see Flex KB). Setup 3
pairs of virtual com ports for DDUTIL-Flexradio, DDUtil-Logic, and
DDUtil-MixW. I am assuming you are using VAC to talk with MixW, if not
Hi Bob,
I believe this explains the situation with Skimmer and SR:
When PowerSDR is tuned with SR on, the I/Q passband doesn't shift
accordingly. It stays fixed. Instead, the decode point in the passband is
shifted. This is equivalent to a small change in IF relative to VFO.
But Skimmer is
I don't understand directly interfacing from the 5k box to Skimmer.
Skimmer needs CAT information in order to control frequency display. If
PowerSDR is not running, where does that info come from?
Also, doesn't the audio buffer coming in from the Flex have header info?
That would introduce at

Before I put this in the request bin I'd like to see if either the
feature is already available or if it is attractive to others.

Hi Phil,
I have done exactly the same thing in the heat of battle, but just
discovered that hitting the escape key resets the frequency to what it was
originally, assuming of course that you have not hit the enter key yet ;o))
Does this solve your problem, hopefully?

Hello Army,
No, not exactly. I find that esc only works if the new frequency hasn't
been selected yet. For instance if I find that the new frequency is in
the window but return hasn't been hit yet, escape will do the trick, but
if the VFO has gone to the new frequency, which is usually some
I've done it also.
I've gotten into the habit...of hitting the Save button when I start chasing
something.
I also put in a feature request a while back tokeep all 'saves' in
memory so you can go back sequentially.
not too often, I get the chance, but once in a while I find two stations I
I've often thought a frequency undo, maybe 5-10 deep, would be 'handy'.
