I have been looking into what I could do with the power output on these radios and I believe using no license just in ITU Region 2 we can go up to 3.2 Watts and with a Ham Radio License (and of course naming your radio with your call sign so you are legit with it transmitting under your call sign, you could go up to 1,500 Watts (I don’t see the need for that much but legally you could transmit with it if required to make the link come up).
Has anyone else looked into this? There are some old cell phone amps that could potentially be used to get the power up some.
