Operating at 472 Mhz instead of 433 Mhz
Posted: Tue Mar 04, 2014 11:56 pm
In Australia we have laws that limit (unlicensed operators) the power output of 433Mhz transmitters to 25mw EIRP (means includes the gains from antenna).

How every we can push 100 mW within the range of 472.0125 MHz - 472.1125 MHz hence I am interested in researching how a Flytron and Orange TX & RX can be modified to operate at 472 Mhz (as I have this hardware).
Have noticed that the code for openlrsng contains the declaration RFMXX_868 for using modified hardware operating at different frequency instead of the usual 433 Mhz, hence the idea seems possible. Although a google search shows no results on this topic so I am not able to find any details on how to do this modification, assume this involves replacing the RF module with a different one.. but which?
Any suggestions on this?
