This operations will end our PA survey. You can mount PCB inside, just observe
small ground spring near the main broadband transformer. It should be positioned in
the way not to touch the nearest coil.
3. Receiver part mod.
With radio in standard position facing us, we need to unscrew the filter board.
Before lift up, be sure that You disconnected Red and Yellow mini coax connectors.
After removing PCB we will have access to TX and RX filters.
To do this mod we must remove almost all SMD capacitors and coils. Which
one? Look at the picture – part of service manual. It will be easier to find them if You
look on upper side of PCB and find two known green coils marked L3024 and L3029
(could be that these green chokes are hidden under the interconnection cables):
Start with desoldering these green ones, with the help of sharp knife lift the leg up and
bent it opposite way.
After removing all remaining elements it’s good to clean the place with IPA alcohol.
