No Mike, there is not. A previous owner took out Q411 and some other components. There is more 'done' in de receiver. I will start to investigate and perhaps I rebuild with original parts or replacements.

Is there a front panel or any place where there is a switch to engage/disengage this mod board ?

Is there a front panel or any place where there is a switch to engage/disengage this mod board ? It does appear that the front panel mode switch is used. perhaps the ANL position switches in this board and it is a noise blanker

I have seen many filter upgrades in an FRG-7 but never one like that, also I do not see any ceramic or mechanical IF filter
|
Hi Kees,
Is that an RCA CA3011 IC? The board looks like an aftermarket 455 KHz improved filter board. Maybe someone has seen it before.

what is the part number on the IC on that board
this mod looks like it was done in the 1980s

Hi all, I obtained a FRG-7 which is in working condition but needs still a lot of attention. An extra PCB is added and I really do not know which mod this is. I hope you can help me! There is also a lose red wire which could be connected but.....first I would like to know what mod this is so I can find more detailed information and connect it the way it should be connected. They also modified the power with a 7812 and....cut of the external 12V cabling. Cleaning rotary swithes needs to be done and.... Does anyone recognizes this? best 73' s Kees PA1CJT

Re: [ADV] Re: [Yaesu-FRG-7] A 3D printed FRG-7 light and power switch knob
Thanks for the reply, Lex.? The knobs on my FRG-7 are all fine but
that power switch is going to go.? I can wait until you can get the
complete switch done.

Hello Greg,
I don't have any complete switches yet (the FRG-7 for parts I
got, didn't have the switchs anymore),
but can send you a set of knobs when you want (still have your
postal adres laying around).?
?
I will contact you in a private message.?

Re: [ADV] Re: [Yaesu-FRG-7] A 3D printed FRG-7 light and power switch knob
Lex,
Whenever you are ready to sell one of the red power switches let me
know.? The one on my FRG-7 still works but is very loose. I sense
that it is getting close to breaking.

I got my self a rol of red PLA (it's a little bit lighter
then the red color of the original knob, but it will do) and
printed me a few power switch knobs.?
?
The light switch knob is also a little lighter because the
darker grey I have is almost the same color as the front panel.
The final result and I'm quite happy with it.?
For who is interested, I have added this story (and more) to my
website :??

Re: A 3D printed FRG-7 light and power switch knob
That is excellent info Steve. And looking that there is a replacement (although not in grey) for the straight-skirt?levers I keep to the rounded-skirt levers.?
Saved the documents on my shack server for future reference.?
And thanks for the compliments.?
Update : Yesterday evening I printed a few more and found out that the margins where to small to make a good and easy fit (filament 3D printing isn't exact science). So today I will be looking at where I have to modify the design to make it fit better.?

Re: A 3D printed FRG-7 light and power switch knob
I second what Randy said.? Terrific work. ? Makes me want a 3D printer even though my FRG-7 has all the original switches! ?

Re: Antenna - need some advice please
Hi fellows thanks for the help , I like the W6LVP but the price is a bit high at $295.00 for
?the unit and $100.00 shipping , I live in Canada in Ontario and would have to check the cost for ?shipping
?to my address , plus the exchange , it’s getting up there . The EME 234 assembled and in an enclosure is
?$106.00 , then I have to get a loop and attachments , the coax cable I would buy here and would need it
?for etheir unit , I will be contacting both companies to see what the total cost would be shipped to my?
?address , thanks again for the help all the very best Rick

Re: Antenna - need some advice please
I've tried several loops that really helped drop the noise floor but varied widely in sensitivity.? My favorite is the W6LVP active loop.? It has a low noise preamplifier on the loop powered by an included bias-T power source between the loop and the receiver.? Not cheap but an excellent performer that should fit in your attic easily, and it'll far outperform the long wire you're using now.
More information here:??
Passive loops like the "youloop" work but are far less seensitive.? You can get one from Amazon here:?
