    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

Icom PCR-1000 off frequency

Hi guys!
I know it's an old radio but I still find they have their use :)
I noticed the other day one of my PCR1000's was about 250Hz off frequency when listening to ssb calls,
so I used the EX-2099 software and hooked up the frequency counter to the CP4 point which should read 10.250000MHz and sure it showed ~10.249750MHz.
However - the software only allows you to tune it +/- 128Hz...

So what could make the reference oscillator that much off, and is there any way to coarse adjust it before fine tuning it in the software?

Cheers!

EX-2099/PCR1000BUR both got it, but it only adjusts +/- 128Hz which is too little.
So it looks like I need a new crystal..

Yes sir I did, even had backups from when it was almost new.
However I solved it by lowering the capacitance of the crystals caps a bit,
a couple of pico and it rose a couple hundred Hz - and fine tuned with software.
Seems to be working a treat so far...
Thanks for the tips though!
