TOPIC: Any Homebrewing in AP

Ismail,

That would be great work. It will help us start the 40 meter sked again.

WAS and thanks for the basic tip I have already tried besides a couple of other comon tricks.
I would suggest to go through the referred circuit of Carrier Oscillator first and keep the physical access, component size and available space relation in mind while advising a solution. The centre frequency of the SB Filter is 3.180 MHz and the Xtal for the LSB is higher than the centre freqyency which has further moved up falling at around -35db at the Pass Band Skirt of the Filter.
Thanks again for your quick response.

Check out the above link. Maybe you can experiment with the crystal to bring the freq back down into the passband.

Thanks AP2AUH!

I have a good hand and had been grinding/loading/unloading crystals for my earlier home-brewed rigs successfully. I'll hunt for a nearby frequency crystal to fiddle with while saving the original one from the risk of open-heart surgery.

The web-site, however, is very useful and I could find a lot more stuff of my interest.
