I don't think that the OP was trying to complain about SSB operators being
less capable or less polite or less facile in their Doppler tuning
correction or whatever in comparison to CW operators. He was just making an
observation that sometimes two pairs of communicating operators have
As long as AMSAT-NA needs to concentrate on 1U/3U/6U Cubesats for the

Note that Jan is specifically asking about VO-52 (mode UV), *NOT* FO-29
(mode VU). There is a big difference. When the uplink is VHF, the third
harmonic of 145 MHz is 435 MHz so desense is often a problem. I have always
noticed that difficulty with my FT-847 on FO-29 in the absence of external
Kevin:
I'm wondering if there is some other criteria besides UHF (I presume in the
430-440 MHz band) and 100-200 watts out and linear operation? Because there
are many amps that meet those criteria.
If you want brand new, you can find them from Mirage (not my first choice,

Well, keep in mind that DEMI's strength is in transverters, and what is
