Just sold a TKR-751 on the ham band with a RC-210 controller and a TPL high end PA 4 watts in 120 watts out all going in a TX RX duplixer and it is killer, very happy the way it works and so is the customer. John

I've done it more than a few times although I can and do more often save the customer the extra $ by doing at our shop. I've not had a problem selling/using the standard K version well down into the ham bands, which means any later potential resale value back into commercial service makes it worth that much more. But whatever works best for the owner is the obvious choice. cheers, skipp skipp025 at yahoo.com www.radiowrench.com > "Eric Lemmon" <[EMAIL PROTECTED]> wrote: > Tom, > > The last TKR-750 repeater I worked on was about three years ago.
