Hello Byron,
Actually there have been several DXers who have replaced the tiny tuning thumbwheel on the SRF-59 (and the very similar analog SRF-39FP) with a large vernier drive tuning system. John Bryant did this with his "National SRF-39FP" modification, with the article posted at . John used a 5:1 reduction drive tuning capacitor from the National Radio Company.
This modification (as well as adding almost any other new components to an ultralight radio) would place the radio in the "Unlimited" category for award purposes, however.
73, Gary

big drop in solar flux 73,2,0

anyone else pick up NJ last night ?

the new SRF-59 has a much lower noise floor than any of my other receivers, but its much harder to tune and to know what freq i'm on. so i have to use a spoting receiver. anyone notice, its made in China ! sure would like to put a big ol vernier drive on it. 36 to 1. wonder if that would still be considered unmodified? ever tried that Gary ?
