[FADCA] Low range and High Range UHF Mitreks - HELP!

[Dan Babilla]

Bud,

I have Mitreks on 430 mhz. I have not had an issue with making them play
down there. You have seen one of them personally, if you remember. I think
your crystals need the proper compensation network component values. The
component values change in Channel element as you move out of band......

We are trying to tune some UHF Mitreks to 430.250 and 430.550 w/o Joy!

We have a garage full of Mitreks and have tuned many to 440.nnn and 446.nnn

The only UHF Mitreks we have include various chassis numbers all indicating
450-512 Mhz range.  In the literature there are other Mitrek chassis numbers
that would indicate 403-420Mhz range.

Must we have the 403-420Mhz range units to get one to retune to 430.nnn?

(We get virtually no RX oscillator activity for 430.nnn with the units we
have - is there a mode for these higher frequency units?

For your reference here is where you can find a lot of reference info for
Mitrek model and chassis models.

Thanks for a quick response if you know for sure!
