Hi Guys, I am looking for some low-frequency (with regard to the hardware I am used to at 868MHz) radio modules in the range of 50MHz up to 433MHz with good Arduino/Atmel compatibility and support base (actually, please just forward me anything). Tools and machines. Code could be ported to other platforms. One interesting feature is that unlike many commercial transceivers, the Ham Shield covers the 2 m, 220 MHz, and 440 MHz bands. I'd like to build a device (using Arduino) which can tell me the signal strength of any transmissions on the frequency (RSSI). Designed with a frequency setting range of 20KHz to hopefully 75MHz, but spectral performance may be poor. But there are a couple of caveats.
