Hi Guys,
I have a MR356-2 duplexer (6 cavity unit) which needs to be tuned to a
new frequency. The original freq pair is 462/467 Mhz and the new freq
pair is 441/446. I have the tuning instructions from Sinclair so I know
how to set up the equipment, but the actual tuning info is sparse (or
I'm missing something). It simply says to tune the rods to the new notch
point.... So I have a few questions:
1. Do the low side tuning rods (3 cavities) affect the high side tuning
(3 cavities)?
2. Since there is no way to use (or measure) just one cavity section
(they are hardwired together), how does the tuning of one rod affect the
others? Do you just start the adjustment from one cavity and then move
to the next?
3. Can you mis-adjust the unit such that you seem to have a notch at
the right point, but in fact there is a better adjustment point?
4. Can or how do you adjust or affect the 5 MHz split? Or is each side
(Low vs High) independently adjusted?
Thanks for your time,
Marc
