One of the HAM bands we should focus on is 222Mhz, it needs more attention.

If the local frequency coordinator allocated us a 10 KHz channel, and we were capable of 2 KHz channels, we would have 5 channels. Here in Northern California, we have lost much of the repeater use of the 440 MHz band due to PAVE PAWS. Frequency coordination hasn't been easy here for decades. 2 KHz channels would be a desirable feature. The most recent Celluar Industry conference was a non-stop commercial for FCC to allocate them more frequencies from start to finish of the conference. People said it played like an infomercial. We potentially have some problems coming up. > Would 'purpose built' be from the ground up, or as a module I think from the ground up. Newer ICOM radios have the codec on the motherboard, we can't really count on current commercial radios as a platform for codec experimentation. TAPR did a pretty good job at getting very many manufacturers to use AX.25 on 1200 and 9600 modems interoperably. Bob Bruninga and TAPR did a good job at getting many manufacturers to use APRS interoperably. We can innovate here, and pave the way for adoption by mainstream manufacturers.
