Thanks for the reply Eric- I am on the Mastr II list also but have not posted there yet. I think what you are saying is exactly what we were suspecting - we added a jumper to the receive and it fired it right up. I have since tuned it a bit and it seems to receive ( on 154 Mhz ) as low as my old Boonton will run as far as sensitivity. We did not know and still don't of course what to with the transmitter. Yes it is a multi channel ( I believe eight ) Number 19D416859G4 Rev K is the board number under # 1 Icon.\ Comb. # MX76KKG66A - is on the outside of the case. Don't know if that's the one you wanted or not Dave

I suspect that you may have a multi-frequency radio, and need to install a jumper to enable the TX crystal. Do you have the LBIs that apply to the components in your radio? I am cross-posting this response to the MastrII list to seek additional expertise. 73, Eric Lemmon WB6FLY NĜATH wrote: > Hello all - I am trying to help a friend of mine get a Mastr II mobile > fired up on 2 meters.We are having trouble getting any thing out of > the transmitter.
