Hi,

?? on the right side of the cabinet (facing at the front panel) there is an access hole to TC7001, located in the VFO unit.

With a plastic screwdriver you can adjust this trimmer capacitor against a RX signal coming from a frequency standard station... it's a very easy procedure that can be accomplished without removing any cover.

With the rig tuned at the same frequency offset respect the carrier frequency, you should receive the reference signal with the same audio pitch either in LSB and USB mode. Obviously make sure that the shift/width knob is properly centered before adjusting TC7001.

I also had my rig about 300Hz out of frequency and now is centered again.

In website you can download the FT-980 technical manual where you can go in depth of any maintenance and adjustment procedure.

Here TC7001 is adjusted by means of a frequency counter connected to the given test point. But if you don't have a counter or you don't want to disassemble the rig, this is the easy way that works as well.

I am fairly sure my actual receive and transmit frequencies are off a bit. Are there simple adjustments to correct? My transceiver is untouched from new except for a batter replacement.
