 Ron K3TZJ, John K9WT, and I had very nice QSO/test session last week and
today using the MD-522 diversity mode for radioteletype. It worked very
well indeed at overcoming fading and QRM. This mode sends identical 85 Hz
shift tones centered at 425Hz and 2805Hz. Come join us or listen in.
Monday 0930 EDT. 7087kHz USB. Mark low. 45 baud.

And don’t forget our regular Saturday morning 850 shift net starting around
0830 EDT also on 7087 USB (2000 Hz center). A couple of the fellows have
used spatial diversity for receiving on that net, with two different
antenna/receiver channels feeding a diversity combiner TU.

Remember, if you don't have a short wave receiver that you can always
listen in via web SDR
