- heywire 10y agoWhile not SDR, there are some cheaper alternatives if you're just looking to mix code and radio transmitting. [1] https://www.adafruit.com/products/3076 https://www.adafruit.com/products/3076 [2] http://www.ebay.com/itm/162086931088 http://www.ebay.com/itm/162086931088
- deutronium 10y agoYeah that's a good point I've got a module which uses http://www.silabs.com/products/wireless/EZRadioPRO/Pages/si446x.aspx http://www.silabs.com/products/wireless/EZRadioPRO/Pages/si4... The chip itself covers 119–1050 MHz, but the modules I have, have filters on to allow only narrower ranges.
- heywire 10y agoI got excited there for a second, I thought you linked the Si468x, which I have been thinking about tinkering around with. It is just a receiver, but it does HD radio which interests me for some reason (it certainly isn't the audio quality :))
- vvanders 10y agoIsolated Audio card & PPT signal + HT can probably be done for less than $100 if you go with one of the cheaper HTs. Heck you can pick up a Mobilinkd[1] for ~$60 if you just want to stick with KISS/AX.25 over Bluetooth. They're really awesome little devices for what they do.
