I've disassembled and compared the ham-split PD633-6A-1N and regular 450-470 PD633-6A-2N. The resonators are identical; they're the same length. The difference is where they are tapped - the low-split model is tapped about 1/4" further up the resonator than the 460 MHz version. The semi-rigid i

I wonder what they do to the internal coupling at the factory when they tune them. Maybe it is something that can be done in the field with a little surgery? Joe Eric Lemmon wrote: > Point taken. One factor that will directly affect how the subject duplexer > will perform at 70cm is where the

Point taken. One factor that will directly affect how the subject duplexer will perform at 70cm is where the original factory tuning was. For example, if the factory tuning was in the 450-455 MHz band, such a duplexer will likely perform better at 70cm than will a duplexer that originally was fac

Correct, but if I remember you were claiming 3dB loss at the pass frequencies. I was seeing about 1.5dB loss. I claimed respectable results, not perfect results. I think it is still acceptable for ham use. Everything is a compromise when you push the equipment past it's limits, but the typi

There used to be an add on board from Comm Spec that could add DCS/DCG/DPL to a suitable radio. Many aftermarket repeater controllers can do DCG/DCS. DCS modulation needs to be sent into a varactor modulator stage... Direct FM exciters on Mastr II can do it native on the CTCSS port... Older Ph

Joe, Your screen shots actually prove my point. Both of the pass plots reveal that your duplexer's pass response is far from optimum, which is precisely the reason for selecting the proper duplexer model to tune. If your duplexer was originally designed for operation in the 440-450 MHz band, the
