Replace one or two memory batteries (main CPU and DRU-2, if installed).

CW Sidetone Level Mod for the AF unit. This brings the sidetone LEVEL (not pitch) adjustment to the front panel MON control; a real plus for any CW operator. SSB MON function is unaffected.

Replace the surge arrestor tube at the antenna lead-in; adjust PA and driver bias as needed.

R&R the AF unit and replace the audio output blocking cap. These get dried out and short, blowing the audio amp chip. 

Clean front controls as needed. Lube main and sub encoders.

R&R the AT unit, lubricate metal bearing points.

60M transmit mod, if needed.

Lube the VFO main- and sub-encoder shafts (we use Mobil One synthetic).

align RF and IF stages as needed.

Adjust power output min and max; MIN goes from ten watts down to 4.5 watts; this makes you "legal" for the QRP contests and much easier to shoot for a QRP QSO, just turn the POWER control full CCW and you are under 5 watts! MAX can go to 150 watts safely on this rig (keep FM, RTTY and PSK31 to 50 watts please). We can also set MAX to a lower value if you want to avoid overdriving an amp. Please note that we cannot exceed a level that would make ALC ineffective on any band.

any other minor repairs needed

on-air check, receive and transmit
