Station Control info
Station Control Module or SCM is the heart of the Quantar station. The SCM comes in different revisons known as EPIC.
- EPIC I
- EPIC II
- EPIC III
- EPIC IV - This is only for the Smart Zone trunking. IT will not work for conventional
- EPIC V
The only difference between the various versions of the EPICs (excluding EPIC IV) is the hardware is newer. There is no difference in functionality for conventional analog/astro/P25 operation.

UHF R1 to R2
Converting the R1 (403-433) to R2 (438-470)
I've done a number of these that all meet spec. If your planing on a conversion it's the best to start with, due to PA isolator covering it, and it being easier to remove material from the preselector than add it.
I've never done a R3 or R4 to R2, I'd like to though.
the R0 is easy as well, but it's got a different design to the VCO's.
Exciter
- Test it first! Trying to modify a broken exciter is like pushing a rope.
- Remove the board from the case and take off the covers.
- Now locate the VCOs (IC3200). These are sealed units and have no diagram. Check out the schematic! The Diagram is wrong when it shows the upper and lower VCO!
- Looking at the VCO I find it's easier to remove the copper shield than
