New for APRS mobile? How about a $12 transceivr that is as sensitive as any modern APRS radio, is frequency agile and has 100 mw TX power operating on UHF?<br><br>It can operate anywhere from 2400 to 100Kbaud on 2 AA cells. I can imagine an APRS distributed mobile data network that can handle 100 times more mobiles plus high data rate transfer of images for better first responder and emergency support type communications.<br>
<br>I'm sure someone has suggested these modules in the past, but I just looked at the specs and am AMAZED at what they have crammed into this POSTAGE STAMP sized UHF transceiver.<br><br>Stuart Robinson in the UK just turned me on to his project to use these modules in small satellties and balloons, but I can envision a "digipeater node" in evry neighborhood, building, tower and hill providing a dense high speed amateur data network! Just hook it to a pic processor for the smarts and make it work!<br>
<br>The RFM22 can use any frequency 240mhz to 930mhz, its available in
versions with the antenna matching centred on 315mhz, 434mhz, 868mhz and
915mz. The RFM22 is a transceiver, costs around $12.<br><br>Seems like everything is there! Go for it!<br><br>Bob, Wb4aPR,<br>
