There is a lot of scope for open source DV and VHF/UHF experimentation, as Jeroen and several others are showing us. The idea of a low MDS VHF/UHF stand alone radio embodying some of the concepts of the SM2000 is still intriguing to me: + efficient modems and low noise figure, so it runs DV in the < -130dBm range (20dB better than FM and 1st gen DV) + LPCNet style wideband codec + something stand alone/portable/HT form factor + minimal hardware lockdown/high performance modem (avoid chipsets with the modem inside) + a few watts power output, proper PA filtering that meets commercial specs But not sure what hardware I'd use these days.
