Here is what I did to get the Micor receive to tune up (908) It will go down to 902. First my receive was on 929.xx mhz. I change 3 Cap's In L101 was a 24pf >>> to 27pf L102 was 33pf >>> to 36pf L103 was 8pf >>> to 10pf this should get you up and going... if L104 & L105 do not tune right than L1...

All you need too do is change some capacitors in the multiplier stages and it will tune up with Good sensitivity .35 to .5 uv And have Good audio!
I done 5 or 6 if these receiver and all of them worked. These receiver are a lot better than a maxtrac a little more work!

Does any one know how to change out the old type controller for the new Advanced controller? What wires & cables need to be added? All I have is the user manual for the Advanced controller and PURC 5000 900 manual. I think I have to add a power supply to the RF tray ?
Thanks Jim
