Follow the hot-link in item 4 in my post above, then see item 5.

Hi Conrad,

Does your 40 degree error seem to be constant for all signals on the band, or does it seem to depend on the polar angle of the incoming signal? The reason I ask is that there is a chance that the I & Q channels for RX2 are reversed in the code, which would be giving us the complement of the true phase angle. What do you think?

Hello Brian.

Things are little hectic right now. I am involved with renovating a property on the same site as the current house, I should have moved this weekend but there are delays, also 6m has woken up!

I will try this week probably not until Friday, Monday busy, Tuesday Contest, Wednesday picking up new furniture for the new shack, Thursday contest - quite a week!

Project is not dead at all just on hold.

Best Regards

Conrad PA5Y

Hello friends!

I repeated all the actions of Conrad, now my system receives two channels (tranceiver is home made from EU1SW theme).
But the question arose about signal transmission.
How to teach to transmit a transceiver at a receiving frequency? I am using split now. But I have to tune in manually. Maybe there is a CAT from MAP65?
