Mastr IIs are pretty good radios in repeater service. Is yours a converted
mobile or a base station with the big heatsink?
G7s have been problematic for repeater service in New Englands climate, not
sure about yours.
Not sure about the power increase on warmup. If you have a spectrum analyser,
does it go spurious? I have seen that, usually cured by a by the book alignment.
I'd sooner look at the duplexer, RX preamp (if used), cables, and the
aforementioned antenna, before swapping out the radio.
There are lots of good alternatives for VHF repeater radios, depends what you
can find, and your budget. I much prefer commercial equipment over ham rigs.

Hi All,
I am looking at the changing radios on our repeater because of the problems we
are having.
We are using a GE Mastr II into a 6 can duplexer and up via 1/2 hardline to a
G7-144.
However, we can not raise the power above 10 watts before de-sense sets in.
Also the radio will climb in power level as it gets hot.
I set it at 5 watts out and by the end of a half hour net it is up to 12 watts
out.
In my opinion this is not right.
What radio would be good for a 2 meter repeater.
Thanks and 73
John, W3ML
