Along a similar theme we actually changed the IF Frequency to get rid of a receiver image and injection problem. Com Spec sells replacement IF Crystal Filter kits if you're up to the task.

And the cost of the Com Spec filter kits is pretty cheap. cheers, skipp > Kevin Custer <[EMAIL PROTECTED]> wrote: > Yes, and as the article referenced below points out, switching > the UHF Mastr II to High Side Injection eliminates the problem. > > We originally thought that HSI eliminated the problem totally on > 220, but it didn't, there is an overlapping range that one side > or the other doesn't fix; that is what is referenced in the text > below. > Kevin > > mch wrote: > > Weren't there some 440 frequencies that had issues, too? > > > > Joe M. > > > > > >> Kevin Custer wrote: > >> > >> I'm not Scott, but maybe I'll do... <grin> > >> See Below.... > >> > >> Yes, there is sufficient isolation for single box conversion with > >> absolutely no internal desense from the MASTR II Mobile, with the > >> exception of the frequency ranges between 223T940/222R340 thru > >> 224T060/222R460.
