With some of the DSP methods on amateur radio today using sound cards, you would be surprised how much fade you can take and still decode data. Modes such as PSK31, FT8 and others can still decode when you cannot actually hear the signal from the speaker. They are very spectrally efficient compared to even SSB voice. As Chuck mentioned if you are sending low bandwidth data it's a viable option.

High power CW can almost always hammer through on some freq. Red cross has a handful of channels that almost always seem to work. -----Original Message----- From: Matt Hoppes Sent: Saturday, December 19, 2020 9:41 AM To: [email protected] Cc: AnimalFarm Microwave Users Group Subject: Re: [AFMUG] High-Frequency Traders Push Closer to Light Speed With Cutting-Edge Cables - WSJ I get that. It’s all good until you’ve got a million dollars tied up in a buy deal you want to dump and you get fade. > On Dec 19, 2020, at 11:39 AM, [email protected] wrote: > -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
