Re: New FRG-7 owner
Here is my H4 hooked up with CH0 connected to TP103 and TP102 and CH1 connected to TP104 and TP105 per the manual. SMA-M/BNC-F adapters and BNC-M to alligator clips. One can do rather better with a

Re: New FRG-7 owner
Miguel, At the time I used my HP 8560A spectrum analyzer which has a tracking generator as the nanoVNA didn't exist yet. The setup is very simple. There are test points at which you inject the

Re: New FRG-7 owner
Well if the red LED is extinguishing that means at TP110 you have enough signal. But it is a tad complex this radio. May I direct you to articles in Short wave magazine written by JL Linsley Hood.

Re: New FRG-7 owner
Reginald, I would be interested in learning how to do the alignment using a nanoVNA, if you are kind enough to share the process. I thought nanoVNA was only for antenna / filter testing; so you use

Re: New FRG-7 owner
Thanks Mike for the hints which were very helpful. I followed your procedure without success: the lock light would never go off (sometimes it would just dim a bit). After touching VR102 as

Re: New FRG-7 owner
Put Deoxit on the switch contacts and align it using a nanoVNA per the factory manual. . It's an easy radio to work on and a really neat design.It deserves its reputation. Have Fun! Reg

Re: New FRG-7 owner
If the radio has been in storage long, take a can of canned air and blow all the dust off all of the tuner caps. That might help you hear something. I have an FRG-7 that was in storage for maybe 10

When you have access to a 3D printer,? you can print your own feet, rear lugs and switch covers. Have have 3D designed the switch covers (see :

Re: New FRG-7 owner
The stuff under the electrolytic caps looks like glue that was used to hold them in place before they were soldered. Look at the top of such caps. Any convex shape is bad news, they should be dead

Re: New FRG-7 owner
I have an FRG-7 in very good condition which I aligned twice. Once to do it and once to be sure ;-) The results were the same. I also have the full docs. If someone hasn't already documented this

New FRG-7 owner
Hello, I collected a FRG-7 yesterday. I thought it was in better shape and probably overpaid for it (EUR100). The overall aesthetic condition can be improved: - It's painted in black. - The

Re: New FRG7 display from Marcel
No problem Pentagrid,I don't see it as criticism. It's the perfectionist in me who wants to get rid of the burdies. To use the light switch is a nice solution. Enjoy your FRG-7. Kind

Re: New FRG7 display from Marcel
Marcel, my comment was by no means meant as a criticism, it is almost impossible to marry any digital circuitry into a radio without some interaction. The oscillator in the micro is a square wave

Re: New FRG7 display from Marcel
Hi Pentagrid, I've noticed the burdies as well, which I don't like at all. I've tried to reduce them by sending only the necessarry data to the display and use some ferrite in the flatcable, but the

Re: New FRG7 display from Marcel
Thanks for the credits Bob. I'm always glad the hear when someone starts enjoying the FRG-7 again. This give me energy to go continue. Apart from the FRG-7, I'm also busy making a display for the RA17

Sadly, its RAINING here in NZ today, so installed the new display..... If it rained more, I would be even happier. Having fat fingers meant it was easier for me to remove the front plastic
