No more or less possible than for ANY SDR1K... and, oddly enough people DO calibrate their SDR1Ks.. You can use any strong narrow band signal to calibrate. It's a pretty simple matter to buy a bunch of $1 crystal clock oscillators and wire them up to a battery. You can actually do it with fewer than one per band, because, after, all, our bands are harmonically related, and besides, if you calibrate at, say, 13.8 MHz, the calibration would be pretty good for 14.2MHz. A 3.5 MHz crystal would do pretty well at calibrating 80,40,30,20,15, & 10... This is nothing more sophisticated than the marker beacon/crystal calibrator that was a standard feature in days of yore (and, in fact, in my 20+ year old FT757). _______________________________________________ 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/
