In the repair industry, these "events" happen with no explanation, and are the worst thing. Do we give the radio back to the customer knowing full well it is not really repaired, but could fail again

Well here's a crazy turn of events.... I removed the cover on the HG unit. poked around a bit. Then removed the enclosure, looked things over and was about to to check the transistor as you

The waveform you see at TP019 is the straight through leakage of the first VFO, this is normal, but not seeing anything as you tune up in frequency on the megacycle knob strongly suggests your HG is

I believe I have the main dial set properly now. Putting the scope on TP019 I get no waveform unless I move the MHZ dial down to the zero mark (where the led goes out) then I get the waveform below.

The HG should provide a very strong fundamental tone at 1 mHz,? especially when the box is removed from the chassis and powered. . Its not uncommon for the crystal to fail. The HG output is at a very

Your other questions..... The slight? resistance you feel at the tuning edges is normal, and is to do with the mechanism limiting the end stops. By loosening the tuning drum center nut,? it can be

I don't think the HG unit is running. Putting the scope on TP106 I get nothing. It's getting the 9 volts. I haven't as yet? popped the lid off the HG enclosure.

Yes, you need to fix those? mechanical issues first. It seems someone has really fiddled with this one The kilocycle tuning capacitor needs careful setting up. With the vanes fully closed, the tuning

Screen grab of output from osc board. Freq varies smooth from 83 mhz @ 29 mhz down to 54 @ at 0 mhz taken at TP 101 /102 gnd.

Pentagrid, thanks for the reply. I did the tests as you described and I could not get any signal on the AM radio tuned to 1mHz positioned near the mixer chip. But I did get a signal at 84mHz when the

The above should have the FM radio tuned to 84 mHz, my mistake.? Most modern digital RXs will tune this low. To test the selective amplifier you will need? some test gear, do you have any?

The only section you need look at is the 52.5 Mhz selective amplifier as mentioned in that article. Unfortunately, that article refers to a receiver that is already functional, yours is not.

Greetings, I was given a FRG-7 by a friend. No clue as to the history of this radio. After cleaning all the rotary switches and volume pot I was only able to receive some local AM broadcast as the

Are FRG-7 for sale ads permitted ?

Hello, For someone who is interested. I've posted a short video on Youtube with the right alignement procedure for the LSB and USB offset. https://www.youtube.com/watch?v=3261CWoSRQE Have fun and

And if you would like to see the digital readout in action, here is a Youtube link: https://youtu.be/HXFUL3ghsbc 73, Marcel de PA8MA

Just a short update about the Ebay link. The previous link has disappeared because I ran out of stock. This is the new one for someone who is interested https://www.ebay.nl/itm/145464409063 Regards,

A quick pic of the few mods I have done to this radio, two diode switched filters, these are? selected via the existing mode switch, SSB/CW? and AM /ANL positions select the narrow, and wide

Here is the plastic lid I used, almost any lid will do, but make sure the wife is away when choosing. I thort bright pink was rather fetching.
