Re: [amsat-bb] New amateur satellite ideas

["John B. Stephensen" <kd6ozh@xxxxxxxxxxx>]

Its good to hear that work is proceeeding. I was worried after checking Phil
Karn's web site and seeing that it hadn't been updated in two years.

A few months ago I volunteered as the ARRL HSMM RMAN UHF project leader and am
busy with the development a DSP-based transceiver for high-speed digital
communication. The design will be published in QEX starting in the
November/December issue. For terrestrial links, an OFDM modem will be
implemented. However the hardware is completely programmable and could be used
to implement a PSK or FSK link at a few MBPS. It would be nice if hams
interested in satellites and HSMM could have interoperable hardware.

I let my AMSAT membership lapse so I haven't received the AMSAT Journal in the
past year and I couldn't find much information on the current web site. Who is
the best person to contact to talk about coordinating efforts?

73,
