I may have tried the ECG618, but I'd have to dust off my old books and look at my notes. It's been years.


I remember buying several different ECG-brand varactors to try on my 148GTL and Grant-XL and one of them was swinging something like a channel and a half (15+), so I took it out. Anything over 10 is overkill as that drops you into the next channel.
