So do we have any more reviews on the rt97 yet? I've been looking around at building a repeater but this is a pretty handy size

I have just purchased and received my RT97. My question is, is it possible to add more power when being utilized as a base unit?

You could add an external power amplifier. But why? Unlike CB, and low-band ham radio, where power can significantly affect range, UHF is limited pretty much by line of sight and terrain will usually stop signal propagation well before power becomes an issue,. If you have a specific communications problem you are trying to solve, power might possibly be the answer. But, as a general rule going from 10 to 50 watts just won't buy you very much.  If range is really important, start looking into different antenna options.

Or a radio with a better receiver. No amount of power you can safely pump on that thing will make up for a 25 dBm desense.

Have 2 operating now, very impressed with coverage. Using  Comet CA-712EFC antennas, short runs of lmr 400.   These are listed on mygmrs.com, Ranch 650, and Copano Bay 675.   The Ranch 650 runs off batteries and solar. located on a hill, antenna at 65 ft.  Copano antenna only at 25 ft.

That paint job Really blended it into the tree!   Interested to see how that holds up , Not sure how water tight they are.

Nice install. But, be aware that unless the antenna’s base is above the tree, the tree is bound to impact the radiation pattern to/from your antenna.
