It has the A to B mods applied, and includes the options for SSB, DSP, 160/Rx ant, etc. I have applied the BFO and PLL upgrades.

> Any help would be appreciated! I mention the following details in case they are relevant: my father was mostly interested in 160m cw, so I?m not sure if other aspects of the radio received attention when he built it. The AF gain knob is scratchy - I?ve read about the mod that addresses this, but haven?t yet applied it. The AGC needs adjustment - I can tell the difference in volume AGC On vs off with no antenna connected. I don?t know that any of these are related to the RF gain.
