1. If the transmit frequency is also off by 4 kHz, then you should adjust the 14.4 MHz oscillator via the hole in the front or top of the RF tray.
2. If it's just the receiver, I would suspect the 2nd oscillator crystal, but it's not adjustable. 3. Could be a dirty connector between the Uniboard and interconnect board in the RF tray, or between the control tray and interconnect board. 4. I'd suspect your measuring equipment and try some other stuff before tweaking the MSF.
