Well my friend said he got it to transmit up there but it disabled my mike
functions so I had it put back where it was. As far as frs, there's maybe a
dozen that use it here so if you were only to use frs you'd be quite bored.
There's a few gmrs repeaters but people aren't supposed to use them. City TV
here has a repeater below frs and the bus company here has repeaters on 412
MHz. I would be more interested in the mrs band on vhf but noone here cares
about it so I guess it's not important.

thats some great info actually.
There are enough different combinations of those jumpers that you can get
rid of the 800-999 coverage and still have the rest of it.
Was just looking at the mod file...you can have
RX 118-174, 300-523
TX 136-174, 410-469
Which for most people is enough since i think the whole point of modifying a
UHF amateur radio is probably for use on the FRS/GMRS freqs anyway hi hi.
I wonder, did you try the 3 different combinations that give you 800-999?
wonder if one of them would allow you to still use the mike functions?
It seems as though you can set the jumpers in at least 3 different
configurations to get the upper UHF band and perhaps one of them will allow
for mike function.
By the way, it won't transmit on 800-999 mhz just receive.
