If you have any kind of MSF metering panel, plug it in and adjust the receive VCO tuning slug for 38uA in position 5. If you don't have one, you'll have to make something up that will plug into the RJ45 metering jack on the front of the station. A simple 50uA DC meter will work. Pins 6, 7, and 8 are ground, the others are RX test points. Pin 5 is the one you'll need to measure and adjust the tuning core.
You can do a similar procedure on the TX VCO. Move the meter to the TX metering jack on the front and adjust the TX VCO for 38uA. The CXB stations were rated for 100% duty cycle. Only the 110w and higher stations had fans on them; yours would need the fans if it's going to be transmitting for 15 minutes or more at a time. The cold weather will definitely affect the VCOs, and that's probably why the VCO LOCK LED is flickering. But you should adjust it with a meter of some sort. You can do a coarse adjustment by adjusting the tuning slug to get the green LED lit all the time. If the VCO unlocks, it will cause all sorts of problems in the receiver, so let's tackle the obvious cause first.
