40M SSB Transceiver, Ham Radio Homebrew

Its in the works. I layed out the board with a CAD software program I downloaded from the website of a board house in Colorodo. They made me 5 boards based on that layout. Its a SSB, 40M transceiver. I had to compromize and order a kit for the L.O. because I tried 10 or 15 different VXO and VFO circuits, but couldn't get them to work at the right frequency. One of them was very close, but no cigar. I don't know if it will work but I should find out in a few weeks when I get the oscillator kit. Most of what is built so far works, but its not completely tested.

That's interesting. Is it a colpitts or a Clapp oscillator? Or a Hartley? Would I be able to adapt it to 10MHz?Are you willing to share the schematic?

Hi obrien135

Some people seem to have trouble with VFOs and Xtal osc's.

I have done quite a bit of experimentation with VFOs and many designs on the net didn't perform well.

In the end I achieved a VFO with exceptional stability and spectral purity.

Not only do you need a good design, but your workmanship must be 200‰.

There is no room for sloppy building when it comes to VFOs thats for sure.

I wish you well in your home-brew work.
