Very true.. But it's interesting.. there appears to be a market for a specialized SDR1K or F5K compatible box with low output power for the microwave folks. Perhaps someone will put together a kit or a new board design that does the trick. Integrated audio A/D and D/A to do away with the cable nightmare. External frequency reference almost certainly needed. Do away with the existing T/R switch logic, so that it's full duplex. Doesn't have to actually have the audio interface on board, if one took an off the shelf interface widget and just soldered permanent cables to it and the RF unit and put them both in a box. (That's what I did with the SDR1000s I was using at work.. just soldered cables to the pads where the miniphone jacks used to be...) Or, a cookbook integration of HPSDR stuff might do? Realistically, it's going to be a moderately pricey board.. in the $1000 range, I'd guess. _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/
