Hey OM:

Yeah, a converter to gets the blocked cell phone bands. They making
those things in some ones garrage in Hong Kong.
Naw the top selling device would be a cell phone jammer. Flick it on
and all the cell phones within a certain radius go down.
A jammer would be highly illegal though, even a police converter
nowadays would be the same: illegal.

Internally most of the good AM car radios I've met had mechanically
ganged slug tuning, although variable capacitor tuning existed too.

I once broadened the band of a Titan 4 reciever by
adding a varible capacitor with a spst it might need another *varible
capacitor with a spdt to get the other end of the spectrum.

That's great if you're comfortable adjusting the mechanics of the
radio internally to get the tracking right. Remember, you won't be
broadening the tuning range, you'll be shifting the tuning range.

You cant find the specs on a converter anymore!
I probably used one of your gadgits back in the 70s, the car am radio
was converted to cb band!

My titan 4 reciever had a trimmer just above the vfo to zero its
frequency with the dial reading!

I simply put the trimmers center point to a toggle switch that led to
two other varible capacitors and could go up or below the cb band,
tuning each to a specified value!

I would love to be able to get a converter to fill in the gaps on a
ubc 780 xlt.
A converter to allow it to start at 100 hz and go to 4 gigs will be
your next best seller without having to use the pc software- Hide quoted text -
