Great thanks for the info, much appreciated?

If you have any interest in the radio as a collector's item I recommend mounting an EMI filter under the power transformer. I was going to do that and had even mounted the filter, but then I realized I could find the IEC socket. Finding a cable clamp to fit would be a long exercise in "hunt the wumpus". And I like IEC sockets whereas I despise permanent cords.
The nibblers are shown on top. I actually used one of the yellow handle ones with the spring and clamp removed for some of the detail work because I didn't have the other at the time.

How did you cut the metal chassis etc?

Re: Antenna recommendation for nursing home setting
With mine I was very impressed that it was quieter than my long wire, as being completely off grid rural, I? suffer horrendous interference from the PV controllers. I bought this just? to try, and now is? in constant daytime use. There are a few dips and bumps in its frequency range, but nothing of consequence. Circuit wise, it uses a balanced video amplifier IC , so any common mode noise, ie, local noise is cancelled to a large degree.. I recommend opening the unit and turning the gain down to improve the signal to noise ratio. There is no need for the 20 or so dB gain it is capable of.??

Re: Almost ready to give up but...
Just wanted to publicly thank a member here for privately offering FRG7 parts.
Good people here.
I've put the FRG7 aside while I torture a Heathkit now.?
If I find a fix in the future, I'll update.
73 for now.

Re: Antenna recommendation for nursing home setting
Indeed a active loop antenna can work well (when you don't have to much noise in the building).? --

Re: Antenna recommendation for nursing home setting
I can recommend this, it is compact, and can be placed inside against a wall. I have one, it works very well. The output cable can be connected to the SO259 aerial connector on the FRG7

The display input connects to the Yaesu tp02 on the AF/IF board, the positive supply to the terminal strip that supplies the lighting, the negative lead grounded. The display will come on/off with the panel lights. Dead simple. just 3 wires.

I am also interested - thanks Marcel

Great, thanks for that.

It is a prototype at the moment with a buffer amplifier for the HF-input and an opamp for the S-meter. The rest is done by an Arduino Nano or Pro mini with an 1.14" tft screen.
Maybe I'm gonna make a kit for it, or send people pre-programmed and calibrated Arduinos. And also a good description how to build it into the FRG.?
More to come.

One easy and cheap way to add a digital frequency display is right here.
Just program the module for an IF shift of -3,455, and it will read the actual Kilohertz receive frequency.
How do you hook it up?

Re: Almost ready to give up but...
Latest update:
Q105 just doesn't seem to want to mix.? It tests well, but it is producing 42MHz instead of the 2-3MHz. ?? The 2 IFs coming in to it are fine.
So I am going to order MPF103's (can't find any 2sk19gr's).?
Meanwhile I'll check all surrounding components to make sure they don't have an issue.
The saga continues....

Any chance of you sharing the hardware and code you used please?

Thank you for your information. That's what I thought already. I have owned a FRG for 30 years ago, and I could not remember if there is a zero beat on carrier in USB position, like the modern receivers.
|
When receiving SSB the BFO is shifted 1.5kHz above or below the carrier frequency for USB or LSB, Most modern receivers allow for this in the frequency display. This is normal. The FRG7 uses a simple LC oscillator, the front panel switch adds a small capacitor across the BFO coil when using USB. The reason for the BFO shift is to keep the SSB signal centred in the IF? filters passband.
