If your plan is to "lock" the transmit frequency so it can never be adjusted to line up with everyone else on the channel, be sure to check the trimmer pot VR5. This is where the "stock" transmit frequency is adjusted when the clarifier does not control it. If it has become "scratchy" over the years, this could cause your transmit frequency to become terribly random from one keyup to the next. A drop of cleaner, and a few excursions from end to end will usually clear this up. Just listening to the sideband transmit on a second radio will reveal if it adjusts smoothly when turned.

Never underestimate the importance of hearing the result of any adjustment to a sideband radio's transmit side. Way too many ways to accidentally make a SSB radio sound like dog doo on the air. Hearing is believing.
