PSK31

I'm using "MultiMode" with my Mac and K3 to decode PSK31. I cannot
get enough level out of the "stereo out" on the K3 to get a good
decode, even though I adjust in software on the K3. What am I doing
wrong? The Mackintosh platform is limited when it comes to radio
software. Are there any other choices?

Re: PSK31

Though I am not sure it will solve your problem, you may want to try Cocoamodem software. IMHO it is superior to MultiMode and is free.

I'll second that! Cocoamodem is the best decoder solution out there IMO..

You should be able to increase the input gain in your
soundcard in order to make Multimode decode correctly.
The K3 has more than adequate level even with Line Out
= 10 to drive most quality soundcards at input gain
around 50%.

In any case, cocoaModem is a much superior digital
application - and it's free. The author is among the
few who really understand the behavior of digital signals
on HF/MF paths. See:

Hi Richard,

Others have already mentioned cocoaModem. Fldigi also runs on the Mac.

Fldigi supports a few less commonly used modes that cocoaModem doesn't
(Olivia, MT-63, Thor, Throb). cocoaModem supports HF-FAX and SITOR-B
reception which fldigi doesn't.

I find Fldigi easier to use for day-to-day QSOs. I think cocoaModem
sometimes does a better job decoding weak signals.

Fldigi doesn't look very "Mac-like" since it's a port of a Linux
application, whereas cocoaModem is a native Cocoa app and so looks
right at home on the Mac.

Give both a try and see which one you prefer.

I will second (er, fourth...?) the props for CocoaModem. I still opt
for Windows for my digital activities simply because I have an old
Dell box that I was able to dedicate to the task and I just love HRD/
DM780 as a complete package for logging, rig control and digital ops.
But I downloaded CocoaModem to give it a try and upon launching it for
the first time I found it decoding PSK31 signals 100% equal to DM780
without even connecting it to the Mac -- it was picking up the audio
from my speakers through the mic input and matching DM780 output word
for word!

Also: if you have a newer Intel-based Mac, you might consider running
HRD/DM780 or any other Windows digital modes app on the Mac using
Parallels or VMWare Fusion. I had HRD/DM780 running on my MacBook Pro
under Parallels and it worked perfectly. I only opted for a dedicated
PC because, A) I had one available, and B) my MacBook Pro is my work
machine and I don't want it tied up during the day for non-wealth
generating purposes.
