Thank you Lex

The FRG-7 display is in production. For the RA-17 I would like to 3D-print the housing of the S-meter, with the display integraded.

Like with the FRG-7, it is my goal to bring it back to its original state within a half hour.

But it will take a while before this kit is ready.

That is awesome, I am sure these will be very popular. I want two when you are in production.? The display is likely a tad small given the bulk of the Racal RA17 front panel, I would envisage it being mounted externally . However, I am impressed very much with your design.

Nice modification,?

Hi,

?

In a previous post, I've announced that I was making a new kit for a digital readout with also a MHz indication.?

Now I've assembled the first PCB's and they function?well.

For an impression, look at

@Pentagrid, concerning your remarks about the RACAL RA-17. I'm in the lucky position to own one now.

I'm busy, finding the right points for the signals and the power supply. The kit will probably replace the S-meter.

For anyone who is interested, please contact me.

Best regards,

Hi,

?

I have my FRG-7 for sale.

?

It is an early version without the "fine tune" control.

?

It is in good condition for its age an works well.

?

I am looking for offers near ?150 and it will need to be collected from RG31 area of Reading, Berkshire UK.

?

Comes completed with original manual and circuit diagram.

Marcel, that is excellent work. Just a suggestion to increase the versatility of your design dramatically. As you know, the VCO frequency of the FRG 7 runs from 55 to? 85 mHz with a 55mHz 1st IF. The very common Racal R17 uses the same Wadley loop design, with slightly different VCO frequencies, this one spans 40 to 70 mHz with a 1st IF of 40 mHz.. IF you could find? a little room to program a few extra? bytes into the "megacycle" routine, a keypress perhaps to alter a pointer to a lookup table, this would increase interest enormously..... there are many Wadley loop receivers? out there.that are lacking a good readout, I think interest would be very high. I would buy two without question.

Hi Marcel,

It looks good and I am glad you got it working well. I am looking forward to buying one.

Hi Chris,

Coming back to your question concerning the MHz readout, it seems my proto is working well.

I could stay to the Arduino, but I had to squeeze everything out. I'm now at 99% of the memory.

I also switched to 7 segment characters. I've included some pictures.

Now I can start to design a new PCB. Hope to have it ready within a few months.

Regards, Marcel
