: hi John, thanks for the encouragement from your web pages. Today I
: modified my '249 with a switch and 940uH inline. the '249 board gives
: even easier access to the switch than the '259.
: Why 940uH? because 470uH wasn't enough and 470s are all I had here.
Thinking of getting a variable inductor for my mod so I can add another
"band" from x-KHz to the current low end of 1.8 MHz using the current
capacitor to tune. I don't need to go too low right now, just something I'm
thinking about...
Some thoughts... Where do those that have the MFJ-249 think the instability
is? The only variable appears to be the tuning capacitor. What if, for the
mod, a fixed capacitor was switched in and a variable inductor used? Any
chances it would increase stability?
Cliff- Can you send me some pics of your mod?
