Reposted to QRP-L. Any experimentation going on for a 30 meter QRP digital
mode rig??


The HOT digital toy on the market right now is the HAL P38 HF DSP Modem.
Clover, Amtor, Baudot, ASCII and Pactor all run off of a TI (I think) DSP
chip that plugs in your PC. $395. I have a Kam Plus and if I was just
starting in I'd take a very serious look at the HAL unit instead.

I still say we need to look at a small "digital ready" 30 meter transceiver
using the NE602 and FSK keying. Then we can hook up these PC's that seem to
always be used for the Internet to do some REAL Radio communicating.

My personal feeling is the PK-232 (and PK-900 clone) has outlived itself and
the AEA DSP-2232 will never see any decent application software especially
at the price it goes for.

Good luck 73/72 Bob VO1DRB/WA6ERB
