One car accident and one new K1EL kit release later, I am finally getting back to the openQRP project.  The ‘proof of concept’ board is up and running but it really did not come up as cleanly as I hoped it would.  So today I posted, what I hope to be, the final oQ transceiver schematics along with a block digram and specifications. You can access them through the Reference link on the right hand sidebar, these are all in pdf format. I’m still working on some things and there might be a tweak or two before I send the release board out for fabrication. The previous board design (REVA shown on the February post) was a good learning exercise and was well worth the effort, one more clean up cycle should do it.  If anyone has any comments or suggestions please post them in Design Discussion are of the forum.

I have also posted the schematics and PCB layout source files in the Design Files/Tools section as well. You will need to download and install the appropriate design tools to view these files.

Thanks, Steve K1EL

I will start this off with the arrival of the ‘oQ’ prototype PCB.  This is a ‘proof of concept’ board, used mainly to debug the Ardunio implementation and transceiver interface.  Over the next few months I will cover the bring up of the board and in doing so introduce the design.
