Hi Jamie Every FM900 I have owned has seemed to have this issue. Mostly I find the VCO is the problem. MY Fix, and attempt at your own risk - (It has worked...
All, Place a guard between the VCO & the other components. I use cardboard to deflect the heat. Rather than heat gun, I use the wifes hair dryer… Solves the...
Hi Jamie, The dot appears when the VCO is out of lock, but it ALSO appears when the radio detects that not enough power is going out the antenna socket. For...

Hi Steve, Welcome to the group. They are programmed vian an eprom. They are a little archaic as they were originally built in the mid 80s but they make a...

Hey all. I didnt realise there was such a following for the ol fm900's. Well, here is the problem. Two weeks after installing my FM92 to my car, its decided to...
To the person with no name... The dot and beeping generally mean the set needs tuning, or that one of several common faults needs to be repaired by a...
sorry, names Dallas. I see. It was already tuned with channels 1-40 amateur band UHF radio. It WAS working fine with those channels. I dont know much about...
Dallas again. I found the problem i was having with the unit being locked onto one channel and beeping at me. It was the soldering around the ariel cable on...
