I had a similar experience with a Philips FM-900 commercial 2 way radio.  In
the late 90s and early 2000s, many of these radios became available surplus (ex
CFA) and were made available to hams for conversion to 2 metres.  They were
quite a good radio, and I had used them when they were in service in fire
trucks in the mid-late 80s as a firefighter.  So for me these radios are a bit
of nostalgia.

However, they had a significant issue - after years of being being joilted
around in fire trucks, the VCO often developed a fault which caused audible
noise on the transmitted and received audio, and in the more severe cases, the
radio would stop working altogether.

The process to fix this was similar - heat the VCO module to reflow the solder.
 On the radio I had, this did fix the problem, but it only lasted around a
year, before the fault returned. :/
