Green/Red LED Lock Mod

 

I intend to carry out the bi-colour LED lock mod on my FRG-7. Are there any detailed photos or diagrams showing where the 10v, 0v and led lock pickup points are.?

The website of monitor.co.uk shows some info but not sure where to get the 10v from and whilst it shows the 0v and led lock connections I'm not sure on which PCB they are.

There used to be a YouTube video from a ham in Finland (I think) which gave detailed instructions but can't find it.

Many thanks.
David G4EDR.?

Da un po’ di mesi ho il mio glorioso eeepc 701 guasto: si e’ rotto il cavetto flat che collega il touchpad alla motherboard. Ovviamente su Ebay non c’e’ traccia di questo minuscolo flat cable… cosi’ ho preso un mouse usb esterno e fine dei problemi.

"One problem is: where to find the + 10V on the receiver board? I found, about 3 cm in front of the original connection of the red LED wires on the board, a pitch that gives me + 10V, looking for it with a tester between the ground and the various pitches. The photo below shows the cables to the original LED (where our circuit is connected instead) and the pitch I used for the + 10V (unfortunately I have a faulty camera, none of these photos are mine)

?

Please, do everything very calmly and carefully: it would be a shame to spoil the receiver for a gross error!"

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


more info at :?
 
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.

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.
 

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 .
