Re: FRG-7 lock light problem

 

But why would it get worse when the radio is on?
I checked all the joints, they look fine.?
Re: FRG-7 lock light problem

 

Hi, sounds exactly like a bad solder joint. Probably at the pcb end. If your handy with a soldering iron, it should be an easy fix.? Hope this helps.?

Hi there.?

My friend very kindly gave my his old FRG-7. It works really well and I love it!

It has one problem. The lock Led will not work, unless the radio was turned off and sitting for a few hours.?
Then, the led will work but only very dimly. The led will continue getting dimmer and after a few minutes it will simply stop working.?
The actual bulb is fine, I know this because when powering up the radio, it will light up for less than a second at full brightness.

It's a strange problem. It seems like as the radio warms, up the led stops working.?

Other than that, everything works fine!?

I will appreciate any help, and I thank you in advance.?

Re: FRG-7 arrival

 

Levers arrived today, so quick !
thanks so much !
Re: FRG-7 arrival

 

I can send a set of levers for Euro 2,65 (send as letter).

Bigger parts (up to 350 gram) which fit in a letterbox package shipping will be Euro 11,50.

Yes, what is the cost including shipping to the USA for the red lever

thanks
Re: FRG-7 arrival

 

When you want to work on your "Franken-frog", I do have "body parts" in stock to fix the monster ;-)?

I have a original volume knop and S-meter in stock.?

Fill this form and add to you comment field the parts you need.?

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-mail-dial-knob

?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
