Deaf FRG-7, Please help

 

Hi,

I have an FRG-7 that has become completely deaf, on all bands. I seem to recall reading somewhere that there is a part of area of the radio that, of pressed on, can wake the set back up. Can someone tell me where that might be??

Thank you,?
Arthur
 

Hi Arthur, Whenever I find a problem with any radio, particularly if it hasn't been used in a while, I shut off the radio and exercise the rotary switches. In the case of the FRG-7 I would start off by rotating the band and mode switch 20 times end to end. This will wipe of any oxidation from the rotary contacts. If it seems to improve the problems then do it again one more time. If it works then all is well. If it comes back again try some dexoxit on the band switch contacts. Use dexoxit by applying it sparingly to the rotary contacts.

If the above doesn't work then some alignment &/or troubleshooting may be required.

Hi Rick,

When you joined the group your email settings were and are “Individual messages”. That means that every message that is sent to the group is also sent to you. To get the least number of messages set your email settings to “special notices only” (Member will only receive special notices from the moderators).

This has no effect. And the MHZ "Lock: lamp stays on. Guess who is in the market for a "new" Frog?
 

Hi Arthur. If you are not particularly technical savvy,, I would suggest you find someone local who may be able to assist. When I recieved mine, the Mhz lock light? only operated on the higher bands. The manual is to be found on the net for download. Refer to this for the alignment procedure. The nature of the circuit means that there are some adjustments that will affect the correct operation of the Mhz lock circuitry. In my case, it meant adjusting the setting of the level pot VR102 (page 12).

HOWEVER .. just do not twiddle this and hope for the best if you are not familiar with the operation of the receiver. You could mark the position of the pot? where it is, only then move it back and forth a few times before returning it to the marked position and see what happens. In my case, it was dirty tracks on the pot (similar to a noisy volume control). Worth a try. Also, as part of the alignment procedure, there are a couple of other? adjustments which can affect the operation of that circuitry. Again, in any case, ask around at your local radio club or some place that may be able to point you toward some assistance. These receivers are fun to use and seem pretty robust.

Thanks, I have a good basic technical background. Given what's going on with the set, I believe there is something up with the local oscillator.

I bought a working second radio. I will keep the first as a parts set. There are no "magic bullets" to get one of these up and running again. But do appreciate the suggestions.
