Radioshack DX-160
 

Does anyone know where I can get a replacement part (variable capacitor) for
the Antenna Trim (I think its C77, 100 pf) on the above swl receiver?

Thanx,

Dave

I doubt you'll find an exact replacement. Try a local hamfest or
electronics store. Look for something that can be adapted mechanically.
The capacitance value isn't that critical, so if you find a 200 pf cap,
grab it.

It's damaged. It just turns freely.

I have a DX-160. I love mine. I bought it from a gentalman who fixed
it up (realigned/recapped...etc) and added the audio mod. It's a
great old analog radio. A lot of fun to fiddle with, although the
tuning (bandspread) gave me fits at first.

You mean the shaft turns but the capacitor plates don't? I'll take a
look at the antenna trimmer cap' on my DX-160 to see what might have
gone wrong with yours.

Been a wile 1977 since I played with a 160
I believe these antenna trimmer does spin 360 (not like a pot, or tuner
cap) .....does it function ?

I hadn't considered the possibility that he thinks the antenna trimmer
control is broken because it turns all the way around. That's what it's
supposed to do, since there is no stop on the shaft. It's different from
the main tuning or bandspread control which have a stop position at each
end of their rotation range.
To use the antenna trimmer control, tune to a particular band or station
and rotate the antenna trimmer knob until you get the highest reading on
the signal strength meter.

Yes, and since depending upon your antenna and the frequency you are trying
to receive, the trimmer may have little or no effect, this could be a reason
he believes it is broken as well.

From what I see turning 360 Deg. a couple of times either way doesn't affect
my receive signal.
