Don’t get me wrong, pushing the Shannon capacity limit is great, but I’ll wager many stations are not even running QRP for the newer digital modes.
- lawfulcactus 7y ago>JT8, etc, have reduced "contacts" to a few bytes I think you mixed up FT8 and JS8 there. :) FT8 is the (effectively) zero-interaction DX mode. JS8 exactly the opposite-- a weak signal mode based on FT8 tailored for ragchewing.
- madengr 7y agoHa ha, I guess the modes in WSJT-X. I know JT65 is one. At least with PSK31 you are typing in real-time. With JT65 it’s fully automated. Ought to only be counted as a contact when it’s below the 2.5 kHz noise bandwidth. When I can hear multiple JT65 signals in SSB audio, that’s totally cheating. Those guys are probably running +10W.
