I have found it frustrating when I am on that freq and THEN they start up.
I wish they would simply QSY when the freq appears busy.

With lots of WINMOR testing taking place, I decided to load up FLDIGI
today and compare its ARQ capabilities. However, my recent fresh
download and install of FLDIGI crashes within 10 seconds of booting.
EventType : BEX P1 : fldigi.exe P2 : 0.0.0.0 P3 : 4a6cce2a

I'm not sure I can ge that far Skip, it crashes about six second after booting
up. Will see what I can do,

Thanks Skip, all is well now.

Sound card users' preference for bandwidth wide enough to receive fifty or
more signals is what makes us vulnerable. W1AW does NOT wipe out the 80m
psk31 sub-band; its CW signal occupies perhaps 50-100 Hz. Use a narrow
filter, and a front-end able to handle nearby strong signals, and the
I think it would be fun to try a test of simple message exchanges on 40,30, 20
meters this weekend to compare WINMOR, FLARQ and ALE (standard and 400) .
It be be useful to have a group of us that can connect and try a message in all
four formats .
I would propose the message simply be

Considering the fact that the ARRL has shamelessly promoted WinLink for years,
despite the well-known fact that the WinLink HF stations regularly transmit
ultra-wide digital hash without listening first, thus crashing legitimate ham's
QSOs by the dozens every day, there's literally no point in

Like almost all large organizations with professional management, the
ARRL has become devoted entirely to the perpetuation of itself. Paid
public relations people write glowing statements expounding the
dedication of the group to egalitarian principals, but to properly
evaluate their motives

have enough dynamic range to be able to deal with W1AW's signal at

Assuming that more than just one or two hams will try to use PSK 31 on 80 m,

From what I have read in the past, there is a difference between inexpensive
sound cards and the high quality ones. I recall past articles that suggest
the high quality ones can result in some very weak signals being detectable in
a waterfall, whereas cheap cards may not reproduce the signal.
Hi, Rik.
Then use a 250 or 500 Hz BW pass band filter. Engage the notch filter. Get
an MFJ 1026 and null him out. Use a separately rotatable loop antenna for
receive. There are a number of things which will work, either by
themselves, or together.
We have or can get filters and other tools.
Hello Andy,
There was a very good article in QST a few years ago about sound cards.
They ran five different cards through quite a battery of tests in the ARRL
Lab and yes indeed, you really do get better performance out of some cards.
But dollar for dollar, the performance was not linear.
HI Guys,
Sorry for the request for help again.
I am confused with my new SL-USB.
I have followed the instructions to the T, and supposably done all the
correct things.
In one statement it says that if the sample rate is 11??? I should change this
to 12000, but if the software is at 8000 then
This is a topic I am also interested in. I have a box full of sound
cards (and several systems with internal sound), and I have tested
several of them using the 'Sound Card Sample Rate Checker' that is
included with MixW (aka CheckSR.exe).
This program checks the sound card against the computer
Hi Andy.
I would say the sound card qualities are very similar to receiver.
Noise floor
Linearity
Birdies and other noise
I exclude timing issues, because they could most often be corrected for with
software. Also I exclude stuff like bad drivers, that would cause dropouts.
