Re: Anyone experience of DB6NT converters/transverters?



Howard,

Your concept of using 116Mhz as an IF to up convert to 1268Mhz might be
workable, but the preferred method is to change the Transverter L.O.
Injection Frequency from say 1152 Mhz to 1124Mhz. This will allow you to use
a 144Mhz IF and be able to change between the two operating sub-bands. e.g.
1268-1270 or 1296-1298 or any other sub-band you care to use as determined
by the L.O. Injection frequency you select. The simple addition of a second
crystal and a switch on the transverter will due the job just fine, since
the L.O.'s are fairly broadband no re-tuning of the L.O. is needed.

Hope this helps.
