I have a UHF Saber III which is about 8KHz off frequency on TX. Its also way off on RX.
I have other UHF Motorola radios which have been around 3 KHz off frequency and I have been able to warp the ref frequency to get them spot on. But 8 KHz seems a long way off frequency.
Does 8 KHz off frequency suggest a problem?
Maybe its dirty contacts/thru pins like with the GM300?
Or is it just the ref crystal which needs warping back on frequency?
Any views?
Thanks
Saber III - 8KHz off frequency

Re: Saber III - 8KHz off frequency
Any thoughts?
Is 8 Khz off frequency on a UHF Saber III more than just normal ref crystal drift?

Re: Saber III - 8KHz off frequency
Did you try swapping out the ref osc with one from one of your other sabers?

Re: Saber III - 8KHz off frequency
Not yet - I was thinking of using it as a donar radio - I have already removed the positive terminal to use on another radio but I've now found an old Saber case I was once given so I can use the positive terminal off that - so I'm thinking whether I can get the 8KHz off frequency radio operational.
8 KHz of frequency seems like too much...although 2.7KHz off freq at VHF is the same as 8 KHz at UHF...so maybe I can warp it back onto freq???
How easy is it to remove the ref osc module?
Can I also easily remove the PA module?
Thanks

Re: Saber III - 8KHz off frequency
All the parts on the saber series are plug in modules. Some have screws holding them in, some don't.

Is 8 KHz off freq a fault or just due to crystal drift which can be re-warped back onto freq?

Re: Saber III - 8KHz off frequency
You can't adjust the reference oscillator that much, an error of this magnitude is NOT correctable by software, you will probably need to replace the oscillator.
Re: Saber III - 8KHz off frequency
I still have a drawer of reference oscillators. PM me your address and I will send you a couple.
