Changing the IF of the XV432 is not difficult from a design standpoint, but requires careful testing with test equipment not found in most hamshacks. A new crystal would be needed in the Local Oscillator and there may be possible changes in a couple of the LO filter components. Next the IF filter would need to be redesigned to cover 50 to 54 MHz and then, finally, the XV432 output spectrum would have to be looked at with a spectrum analyzer to assure that all spectral purity requirements been achieved.
The K3 cannot cover the range from 30 to 32 MHz because of a bandstop filter that has been included to suppress 6 meter image responses. 73, Bob, N6CM On Mon, Feb 16, 2009 at 6:56 PM, Doug Faunt N6TQS +1-510-655-8604 <fa...@panix.com> wrote: > How difficult would it be to modify the XV432 to use a 6M IF? > > Or perhaps the K3 could use 28-32MHz when in transverter mode? > > 73, doug > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft@mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
