I¡¯d say that 100 kHz is definitely a time to retune.?
Normally, on 40, I¡¯d re-dip every 50 kHz, including the driver tuning.?

How does one re-tune a TR4Cw when moving to a new frequency? ?
There are a lot of videos and documents on tuning a TR4Cw on a specific frequency, but I have not seen any instructions on how to touch up the tuning when going from say 7.160 MHz to 7.258 MHz. ?
I finally have my TR4Cw on-line and can tune it up on a frequency, but:?

* ? ?How do I touch up the tuning? ?Certainly there has to be a better way than to start from scratch and tune up on the new frequency.
Thanks,
