SDR architecture versus the old superhet, an inboard tuner, and extend the frequency ranges to cover the license-free portions of VHF & UHF for...reasons. It was an incredible little radio with one overlooked feature I'd come to really, really appreciate over the years: Single Side Band (SSB) on VHF and UHF. Why is that important? Well, its simple. In the land of the blind the one-eyed man is king, so to speak, and in this case that absolutely applies to communications security (COMSEC).

For those that don't speak science that means anything in any other mode goes unheard. Security through obscurity. Enter Amplitude Modulation (AM) and Single Side Band (SSB). SSB communications on VHF kinda went by the wayside over the years with fe
