FRG-7 arrival

 
Edited

well, my FRG-7 arrived today
poorly packed and the volume knob smashed
the power cord cut
the S-meter seems stuck
it does receive


there is only one possible use for me

the creation of FRANKEN-FROG !!!!!
Re: FRG 7 Switch supply

 

Thanks, the FRG-7 I purchased still has not been shipped and I am waiting until I receive it before buying anything for it.

Re: FRG 7 Switch supply

 

Mike, I have send you a private message, but maybe it's stuck in a spam filter.?

?

When you still need the knobs I can send you a set in a envelop.

Fill in my order request form :??and select "FRG-7 3D printed switch knobs" and International Letter for shipping.?

Sorry my 3d printer friend decided to leave Calif.? So I haven't found another.? I do have a Grey switch lever though if you can use it let me know.

Re: FRG 7 Switch supply

 

Do you have an update on a switch lever ? I need a red one
Re: Issue with 1MHz not locking

 

Yes, that's all it was... just needed a tickle of VR102 so the lock light was less fussy.? Thanks!
Re: FRG 7 Switch supply

 

I'm curious about the design the 3D printer is using.

I have designed spare parts for my FRG-7's and made the files are publicly available (for non-commercial usage).?

?frg7-swknob-01


When you have your own 3D printer or have access to one (ask family, friends etc or sometimes even libraries have them).

I have found a possible source for FRG7 switch handles.? This 3D printer made me a spinner knob and it works perfectly. Will let everyone know when? I get a quote.

My lock light would not light up when I ran the FRG 7 on internal batteries.? Member feedback suggested I had to adjust VR102 until the lock light would then come on for each band.? Maybe that will work for you too.

Subject: [Yaesu-FRG-7] Issue with 1MHz not locking
?
Hi all,
My recently restored FRG-7 has developed a slightly annoying problem.? When cold, the 0, 1 & 2 MHz bands won't light up the 'lock' LED.? After some time warming up, the 0 & 2 MHz bands will lock, but the 1 MHz band never does.? However, at all times, if I centre each MHz selection, the receiver works quite OK on all those bands, receiving signals just fine.
When going through the restoration, I replaced most capacitors - electrolytic, mylar / greencap / polyester - but not any of the disc ceramics.? Q102, 103 & 105 were replaced, too, but that shouldn't have any bearing on the lock LED lighting on some bands and not others.? I realigned the FRG-7 back about 6 months ago, and all was fine then.

The problem is likely to be either with the comb generator Q301 / D301 / D302 not producing enough level down around 3-5 MHz, or the 1st oscillator Q201 not producing enough level down around 55-57 MHz, or perhaps an issue with the mixer Q106.

Maybe VR102 is simply just set too fine?? Before I go ripping into the radio and checking levels from the 1st osc or comb generator, has anyone else experienced this issue, and recall what the cause was?

Thanks,
Jason

Looking to buy a GAR-7 digital display

 

Hi, I'm looking to buy a GAR-7 digital display.
Any leads on this would be appreciated.

Re: What mod it this?

 

see if the board is routed through the ANL position of the mode switch
Re: What mod it this?

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
Re: What mod it this?

 
Edited

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
Re: What mod it this?

 

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.
