Troubleshooting mystery with Monitor radio.

Hi sometimes they add a few turns of wire to the Ocs and call it a Gimick...My RCA AR-88 has that on its Osc. Fix the wires and bet it plays nice.Sprman

Hey Sprman, I've seen 'gimmicks' on some crystal sets ... that's certainly what that pigtail on the schematic looks like.

It plays pretty good with the antenna hooked up correctly ... But would like to make it proper if I can - figure out what wire went to.

Thanks for the help!

Its usually used to make a capacitor .

If you will notice in the schematic that the external antenna has no connection to the loop antenna but goes straight to ground. The external antenna does pass the signal by induction as I'm sure there is small loop on the loop antenna for induction. That may help you with your connections.

Ron Ramirez has a nice article on gimmicks for a model 80 Philco that you may find enlightning.

it is as cliff says the external ant. is just close coupled to the rest of the loop there is no danger on hooking a ground or ant. to this connection.many of these sets perform poorly without an external ant. only picking up a few local stations.the other thing is loop antennas are directional sometimes turning it 90 degrees makes a world of difference.butch

THanks to all for the excellent help ... and prodding ... after me looking over the obvious for 10,001 times.

I'll experiment around with the external antenna, as well as, conduct an alignment.

Glad to help Nashvilles old radio swap meet will be in April 2012 ,dont have the dates in front of me tho. Stop by fun time food and great people..Sprman

Sprman ... will it be at the Fairgrounds? I know the flea market will be the last weekend - and that's where I found this particular radio, as well as a working Magnavox 'Magnasonic' that works, although the Collaro turntable needs some attention .... and an Olympic 7-536, but I haven't even started on them.
