Re: Digital readout
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

Re: Digital readout
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

Re: Digital readout
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

Re: Digital readout
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

Re: Digital readout
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

Re: Digital readout
Hi Marcel,
The display looks good. Have you tried checking it's accuracy with WWV on 5, 10 & 15 MHz?

Re: Digital readout
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

Re: Almost ready to give up but...
Accusing Mr Elliot of lying? Certainly not, and what a stupid allegation.
I do however question the parroting of unsolicited allegations of fake components from unknown sources. For instance, unwanted

Re: Almost ready to give up but...
This is getting off topic, my final comment.
If fake transistors predominate just the audio world, it does beg the question, why?
Vacuum tubes for instance , they look for the brand name, the colour

You stated unequivocally that "most transistors sold on Ebay are fake".? This is untrue and an unfair generalisation.
More correctly, SOME transistors sold on Ebay are fake. .
