3D printed FRG-7 main dial knob.

 

For those who are in need of a FRG-7 main dial knob and have a 3D printer, today I took the knob of my Frog and started drawing.
?
The STL files can be download from : ? (also link to the TInkercad design to modify it to your needs).
?
?
Enjoy and hope it helps.

I wanted to print one, but my son has claimed my 3D printer for the next 15 hours. ?

Re: FRG-7 main Tuning Drum issues.

 

Hello Gerald,

?

There is indeed a stop system on the main dial. Mine also had problems and only needed some cleaning. Checkout my FRG-7 mod page on my website.

?<< image showing mechanism.?

Good luck.?

Re: FRG7 LED upgrades.

 

Yesterday I received the prototype PCB's and couldn't resist assembling one set. In the evening I took one of my Frogs with a few defective light bulbs and replaced the PCB's

Initially the light was to "white" so I used a?Orange Edding 3000 permeant?marker on the LED's to get a more "light bulb" warm glow.

More photo's incl. on how to replace the main dial light bulbs can be found on my website :?

Enjoy.

Re: FRG7 LED upgrades.

 

Good work Phil! I love the idea of the eccentric self-locking bush, I will ask a friend with a printer...

I will use amber LEDs for the warm illumination

The main dial light bulbs are burned up, the rubber is falling apart and I know that getting these light bulbs is getting harder by the years (some local stores ask $4+ for them).
So I wanted to replace them with 5mm warm white leds.?I designed a 5mm led holder which slips into the bracket for the light bulbs. First prototype fresh out of the printer. Looks good and it fits (due to a difference in diameter on the center section, it slips into place and when rotated 90 dgr. it locks).



Bought some nice 5mm warm white leds and installed them.?



The result. The leds are less warm compared as the soft glowing original light bulbs. Maybe some red / orange dye could warm it up a little.



When everything works out, I will publish the STL file on my website for download to print you own spare parts to keep your Frog in good shape.



Also I started to work on a drop in replacement voor the PB-1560 PCB's (the light bulb PCB's between the MHz and Select) with 1206 SMD leds with the same color. I use 2 leds for each segment because the 1206 leds aren't that bright and this way you get a better light spread. Just simple testpads to solder the wires to.





(Yes I know MHz is with a capital H ;-) )
Hope that before this weekend the SMD 1206 LEDS arrive so I can make a prototype to see how the light looks.
When all goes well I'm going to order a batch of prototype PCB's and upgrade my Frog.

Re: FRG7 LED upgrades.

 

I edited the page on my website to include a link to the TinkerCad 3D design for the LED holder and made the design publicly available so you print your own but licensed it .

Meaning :?

  • Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.
  • NonCommercial — You may not use the material for commercial purposes.?
  • ShareAlike — If you remix, transform, or build upon the material, you must distribute your contributions under the same license as the original.

It's not to be childish but it now happened a few times that a 3D design I made was sold by other people just because is was "Open source, so I can do anything I want with it" without any credits or even a token of appreciation.?

Printing settings I used :?

  • Material : PLA
  • Layer height : 0.12mm?
  • Infill : 100%?
  • Support : Yes

I have made the modification and it goes well. I would like to put a frequency counter on it but I don't know where to get the signal from.

Re: Lock

 

I took the hood of my FRG7 and the values I measured are :?

Unlocked (led on) = 1.9V
Locked (led off) =? 0.29V?

?

But have to say that I have modified my FRG7 with this a bicolor led mod, see :? https://www.ph2lb.nl/blog/index.php?page=yaesu-frg7-mods

What voltage does the Q111 emitter have to have for the Lock led to turn on?

I live in Seville, Spain and I am trying to restore, both electrically and aesthetically, the FRG-7. Thank you very much for your interest.

Re: Mando sintonizador para FRG-7

 

Hello Rafael,

I will take a look in the shack (might be one in my spare parts section).?

What's you location / country ??
Mando sintonizador para FRG-7

 

Recientemente he adquirido una FRG-7? a la que le falta el mando de sintonización. Si alguien tiene algún mando para vender le agradeceré me indique el precio pues estoy interesado en adquirirlo.
Saludos
Rafael

I recently purchased a FRG-7 that is missing the tuning knob. If someone has a command to sell, I will be grateful if you indicate the price as I am interested in purchasing it.
Cheers
Raphael
Re: Green/Red LED Lock Mod

 

Thanks All for this thread. A useful Mod! I combined it all into a new pdf in the files section. Monitor Internet - FRG-7 - MHz Lock Red_Green LED Mod.pdf .

Re: Green/Red LED Lock Mod

 
Edited

Many thanks to everyone who has read my post and to those who have replied. I now have all the information required to successfully carry out the mod.

73, David - G4EDR.

UPDATE

Just completed the mod and it all works great. Despite having access to more modern receivers I always enjoy 'driving the FRG-7 and this mod makes it even better. Again, thanks for the help.
Re: Green/Red LED Lock Mod

 

I also have the mod in my FRG-7's?
This is a close up from the wires :?

Yellow/Green = signal

Red/Green = 10V

Blue/White = GND
