I wish I had gotten involved with the digital modes on VHF earlier. I quite enjoyed using FSK441 and JT65B and C on the VHF and lower UHF bands back in 2015 and 2016. It seemed simpler then, FSK441 f

Although 1.2 GHz may not be considered a microwave band, I have used JT65c on that band with success during a portable outing. It allowed us to quickly complete a QSO that had defied several attempts

I don't believe I have ever used WSJT-x with my FT736. I have however used the same interface hardware with WSJT-x and another radio and I don't recall any issues. In this scheme, WSJT-x just sees a

My suggestion would be to stay well clear of the APRS frequency. In my experience over the last several years, weak signal work and near by FM don't always seem to co exist well. 73 Mark S VE7AFZ Mar

The pragmatist in me is happy to see interest in continuing to offer SSB / CW radios that cover frequencies over 144 MHz. But yes coverage of bands such as 222 MHz and 902 MHz would be nice. 73 Mark
