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

Re: Antenna recommendation for nursing home setting
Hi, could you please document or show some pictures of how you did the emi socket
I also have being thinking of doing the same as i have a spare emi socket sitting here unused at the moment
How did you cut the metal chassis etc?
Thanks

I modified the? radio today and installed an IEC socket with integral EMI filter mostly to improve the ground situation and simplify cord handling.

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....

Hi Marcel,
Any chance of you sharing the hardware and code you used please?
TIA,

Here is my version with a color TFT screen.

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.
|
Hi Roger, unfortunately I can't receive WWV here in Europe. But I can receive a Russian time signal on 9.996 MHz.?
My Frog has a Kokusai filter. So I had to reallign the BFO. In USB position, zero beat is not the same as the carrier frequency. I have checked it also on broadcast stations. It is always 1,5 kHz above the frequency.?
Does your Frog has zero beat on the carrier??
When the signal is exactly in the middle of the filter,? the frequency on the display is spot on. So the counter calibration seems to be okay.?
|
Hi Roger,
No I didn't check that. The counter has a calibration routine. I have calibrated it against a high precision Rohde&Schwarz signal generator. So the indication on the display is exact the VFO frequency.
I will listen to the WWV transmitters and see if they match.?
|
Hi Marcel,
The display looks good. Have you tried checking it's accuracy with WWV on 5, 10 & 15 MHz?

Hello, I saw the discussion about the digital readout. I've just finished one for my FRG. It is based on a OLED display and an Arduino micro pro.
I only took the S-meter away, which is still connected and remains in the radio.?
I'm also busy making a version with a TFT color display.
