Measure VHF Antenna (Cable) ?
 

Thanks for all the input!

Turns out (after spending more time on it than the 1980's
VHF is worth) that it was the loudspeaker that had failed.
Nice reception with earphones conected to the speaker wires.

So where do I get a replacement speaker?

Thanks!

Well, Radio Shack might have something.

Simplest solution would be to use an external shielded speaker (e.g.,
West Marine) that you could plug in to the radio. Does the radio have an
external speaker jack?

Name one in LA.
Radio Shack isn't it: "Uuh, raw speakers? Not any more, sorry."

Some antennas have a loading coil at their base. This coil is across
the center cable conductor and the shield, so if you use an ohmeter to
measure the resistance of the center conductor to the shield, you will
get a "shorted" indication.
A better check is to find a ham in the area, and see if he has an
'antenna tester'. This will operate the antenna at the intended freq.,
and show if there is a problem with the cable or antenna.
But first, make sure your VHF radio is not at fault, by checking the
squealch setting, and volume control as others have mentioned. You
should hear something from the VHF, even without the antenna
attached...BUT DO NOT TRANSMIT -as that would cause problems with the
radio possibly.

(Near zero ohms with the cable disconnected from the transceiver.) That was
a common failure mode on the old Nike missile system. Where the cable makes
a sharp turn the center conductor would push thru (slowly) the insulation.
Wiggling the cable to detect an intermittent short is also something I would
try.

Of course, if it is shorted and you tried to transmit, you may have fried
the transmitter.

Anything I can do with the multimeter I have here?
