Thanks for the update. That will make working NO-84 much easier. I was 
making a macro for every station I worked/saw on the down-link. I was 
running out of room for the buttons.

Thanks again...


I have updated DopplerPSK to v. 0.20. 
<http://www.frontiernet.net/%7Eaflowers/dopplerpsk/dopplerpsk.html> 1. A 
"message loop" feature to aid in QSOs or other experiments where it 
might be desirable to have a message sent in a loop.  The message format 
and UI is similar to that used in WSJT.  Hopefully this is useful for 
slow typists, especially when fading and/or SNR is a problem.  See the 
new Quick-Start guide for details on how to set up your own messages if 
the ones provided are insufficient. The original keyboard-to-keyboard 
mode is still there on another tab. 2. Fixed a couple bugs with saving 
of station information. 3. Updated  the Doppler correction updates to 
once-per-second instead of every 5 seconds.  This should improve 
tracking on very high elevation passes.  In these situations it is 
critical that your clock be synchronized with UTC as close as possible 
to minimize residual frequency drift. 4.  Added ability to select a 
sound output device separate from system default.  This isn't 
extensively tested, but those of you who have multiple soundcards for 
your digital stuff might find it useful. Please let me know of any 
problems. Andy K0SM/2
