Why not use a small "brick" with an appropriate interface. Something like W5OOR's SuperPacker Pro has a microcontroller in it that could be used to provide an interface. Obviously, you'd need a different design for 6m. But, for a "tinkerers" radio system, a series of decently designed modules is probably a better strategy. Having done this kind of thing (assemble digital and RF modules into systems) for a living for many years, I would also encourage settling on some standardized chassis form factor, so all the modules stack nicely together. And, for gosh sakes, standardize on where the cooling vents and connectors are. I can easily see something like a SDR1000 TRX module (with the DDS and the QSD/QSE) mated with a somewhat different interface module (so you aren't tied to printer ports) and a couple buffer amplifiers that has a RF out and RF in connector at the few milliwatt level. You'd mate that with a 100W amplifier module (which would include the LP filters) for HF and/or with a tuner module,e tc. >Robert M0RWB > >-----Original Message----- >From: [EMAIL PROTECTED] >[mailto:[EMAIL PROTECTED] Behalf Of John Basilotto >Sent: 03 January 2007 14:30 >To: 'Ross Stenberg'; 'Reflector' >Subject: Re: [Flexradio] Price Increase and 1 watt SDR discontinued > >We don't know at this point.
