Fellow Frogers,

? Just picked up a new-to-me FRG-7 and noticed what seemed to be an unkown mod consisting of a DPDT slide switch (S-7) w/ two? resistors (R-18 & 19), connected to the internal speaker.

But surprise, some of the schematics show these components in the lower right near the speaker.? However, they are not on the parts list, nor are they mentioned in operating / calibration instructions or circuit description.? There are no related labels on chassis or cabinet.

The switch is physically attached to a frame brace in the upper right rear of the chassis, just below the white battery plug/socket.? Switch is poorly positioned and clearly not intended to be accesssed often or easily.?

The resistors are either switched out of circuit, or placed in series w/ speaker: one between audio & speaker, the other between speaker & chassis gnd.

The only in-circuit effect seems to be some lowering of the volume.

Serial # 300585 and apparently this radio lived in Canada at some point.

Any idea what this undocumented "feature"? is about?

Hi Andrew, The FL-101 transmitter looks very similar to the FRG-7. But when the FL-101 is used with the FR-101 the pair will work in transceive mode after the interconnecting cables are attached.

I am looking for an aftermarket speaker replacement for the main speaker on the FRG-7. Has anyone had success with finding one?

Thanks, Lex, for that 3D-printed knob design. I was lucky enough to find an original knob on eBay. Also, thank Cesar for your reply. This is one neat radio. I am researching a suitable AM transmitter to get more out of the one AM channel. I might consider building one from scratch and looking into a loop antenna for the USB and LSB. Does anyone know if this receiver had a transmitter that went with it, like the FT-101 FR-101? Or was this just a stand-alone unit?

The knobs of the first model FT-101? look like the on a FRG-7.

But the knobs you are pointing to in the e-bay link are from the newer models of the FT-101 (E, ET, Z, MD etc) and look like the one's used on a FRG-7700.

Looking at the prices on e-bay for original knobs, scared the hell out of me.?

Read that ft 101 is the same. Found this:

Hello Andrew,

These are very hard to come by. I had the same problem and often 3D print parts, I designed my own (as close as to the orginal as possible).?

?

So when you access to a 3D printer (of not ask, friends, family, you local community center) you can print your own.

Wondering if anyone has the main tuning knob they would be willing to sell?

I should have mentioned my goal is to replace the kHz drum with a 3 digit display

I used some of these many years ago and they were awesome deals
unfortunately they are discontinued

Thanks but my budget is around $20

Hi Paolo,
?Thanks for the display info. I copied your pdf's over to the files section and added translated english versions as well:? /g/Yaesu-FRG-7/files/6%20-%20FRG-7%20with%20non%20GAR-7%20Digital%20Readouts/Paolo%20Viappiani%20Display? .

Hi, please look at the attached articles (unfortunately they are written in Italian, but almost easy to be read).
Good work, regards!

has anyone added digital readout to their FRG-7 this year ?

I just took delivery of a fixer upper FRG-7. I did a full alignment but was still disappointment with the results of this receiver. So I put in on the bench and found that L101 (4 coils on a rod after the RF AMP) the first pin was not soldered to the coil wire. See picture:

After soldering I am now getting a 20-30 dB improvement in reception. At 1.5 MHz -55dBm gave me S9 before soldering now I get -78dBm giving me S9.
I have a question do others have this coil not soldered and only wire wrapped. I am just curious if this was Yaesu's manufacturing process or if this was just forgotten to be solder and thus a defect.

This is my first post so it might take time to post. Thanks for your time.

Great job Lex,

I have two suggestions:
I believe that spun replacements for the metallic inserts are available from restoration places but may have to be cut to fit.
If you use ABS in black you can soften or eliminate the printing lines with an acetone cloud in a plastic bag.

Recently I got a question from a fellow ham if I have a replacement knob for the Fine-Tune. Unfortunatly I didn't but told them that I wanted to 3D design all the knobs of the FRG-7.

So during my holiday I started to work on the 3 knob of the FRG-7. The one which can be used for the Preselect, Mhz and the Volume.

My first prototype print (0.12mm / 100% infill) next to a original knob of my FRG-7.

I'm quite happy with the result and will continue working on the others. So when you need replacements knobs, stay tuned. Soon they will be ready and released on my website.??

I have noticed that the lock light in my FRG-7 dims with humidity. I doubt this is the problem that yitzimarks@... is observing, but I toss this observation in to see if anyone else has seen that issue and resolved it.

Hi,
I hope it's not too off-topic to discuss the 8800 here as I can't find a dedicated group for this RX. Mine has problems with excessive contact bounce in the numeric keypad. What is the construction, is it membrane keypad or are there individual switches that can be cleaned?

Apart from this and the occasional PLL lock issue when it gets to warm, I'm happy with how it performs.
