Hello,

I was researching used radios last night and noticed an abundance of somewhat cheap 900 Mhz radios. I was wondering if there was a way to use these radios which most of the time extend into the 5-15W power range. I was thinking use something like a RPi with the TNC Pi. Can this be done? Has anyone done it? I think using more power with a better propagating 900Mhz band has many useful benefits.

Do you have a link or more info on the 900 MHz radios you are talking about?

If you are talking with TNC, then why spend $400 to be on 900 MHz? You can do the same with VHF/UHF radios. I thought you'd at least be talking a radio designed for data. 19.2kbps UHF MDT radio: http://www.qsl.net/n9zia/gemini/index.html

I'll look into those but the whole reason for the radio is it could communicate with the 900 Mhz gear. If it can't be done then so be it II just have ideas pop into my head.

Can't be done. If you are talking communicating with the Ubiquiti 900 MHz products. Those use spread spectrum, what you are talking about is a narrow band voice radio. Same bands, but totally different modes/protocols. Its like a CW radio talking to SSB on the same band, no go.
