Re: Counter plug on rear of my FRG-7
Hi Greg,
I can't find my GAR-7 manual but the VFO signal is present after the VFO buffer transistor Q404 at TP404. I would pick up the signal there using a .001 uf cap in series with a 470 ohm resistor. Use RG174u coax to a new RCA jack on the rear panel.

Re: Counter plug on rear of my FRG-7
Hello fellow enthusiasts,
?Interested in adding a digital dial to my Sears version. ?I would guess that the "readout" jack is connected to some oscillator via coax and a small cap.
? Don't see any info in files or picture sections. ?What do you see in your radios for cap value and PCB connection point?
Thanks,
Greg // KE7NJS?

Re: Counter plug on rear of my FRG-7
Hi Louie,
Welcome to the group. I have one of the Gilfer Associates GAR-7 digital displays. I put a new folder in the Files section with some GAR-7 pictures, from eBay, in it. The picture of the rear of the FRG-7 shows the missing red label that has fallen off your FRG-7.
The counters were not actually made by Gilfer. They were made by e-tek. Their main claim to fame are the FR-4 digital displays for the Drake R-4 series of receivers. I have added a picture to the new GAR-7 folder.
The GAR-7 is a simple offset counter. It counts the VFO frequency of 2.445 - 3.445 MHz and subtracts the IF frequency of .455 MHz. This indicates 2.0000 to 3.0000 Mhz on the display. Because the GAR-7 only shows the last 4 digits you see 000.0 to 999.9 on the display. The accuracy is dependent on the FRG-7's 1 MHz crystal. I don't see a trimmer for zeroing the 1 MHz crystal, in the schematic, but someone may have addressed this problem in the old messages section.
A number of suitable 4 digit offset counters have been offered over the years. Probably the smallest with four 1/2" red LED's is the S & S Engineering PC1. It measures 5 1/2 by 4 by 2 1`/2 inches and has DIP switches for setting the offset required. S & S is gone but they go for a song on eBay. I'll try to find a picture for the Gilfer folder.

Counter plug on rear of my FRG-7
Hello FRG-7 users, i have one heading my way and on the rear there is a port simply labeled "counter".....According to the prior owner, he said "? Gilfer Shortwave and Electronic Equipment Bank were big shortwave radio stores back in the day and they did mods to Frog 7s to take a digital counter." The thing is I cant find much information out there on what kind of digital counter it could take and if its something others here have seen.
Thanks,
Lou

Re: Deaf FRG-7, Please help
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.

Re: Deaf FRG-7, Please help
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.

My Frog finally gave up the ghost. Does anyone have a good, solid working Frog that they don't think is worth the Moon, or, eBay prices? I'd love to buy a replacement. Please let me know. Thanks, Arthur

Re: Deaf FRG-7, Please help
This has no effect. And the MHZ "Lock: lamp stays on. Guess who is in the market for a "new" Frog?

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,
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,?

Usenet and rec.radio.amateur.equipment
A little history;? during the wild west of the internet, (1980) the?User Network or Usenet was?created.? It was the first public forum for information exchange?and was huge.? You can wiki it.
The reason I bring this up is that it covered the timespan for the FRG-7 introduction and most of the FRG-7 modification/development.? The groups were named in the following format:
rec.radio. (something)
rec.radio.amateur
rec.radio.amatuer.antenna
rec.radio.amatuer.equipment
rec.radio.amatuer.receivers
and so forth.? Google kept about 20 years of archives, and if you dig a bit, there is more info about Frogs than you can ever use.

Link to old FRG-7 mod page.
I'll try to start putting some FRG mods and reviews into the file pages soon.
Here is a link from the past that still works, too bad they didn't complete the ambitious start they made.
