I thought I had the plan clear in my head. first 6 wires was easy. or so I thought. Realized when I started with the other six I was wrong. On this pic only a few are connected and the second toroid going on top is not even there.
So.. just to start all over again.
Had to start all over again with the receiver. Had the wrong version of PCB layout. A bit easier with the new one. More room for the coils in the ring diode mixer.
Started with a new card and new components so now Im back where I was before. Tomorrow the coils will be mounted on the card. A LOT of tiny wires. And somehow I have a feeling they must be in the correct hole.. 12 of them.
At least its a start. Hopefully smoke test of the receiver part on tuesday.
Have it working from 3.45 to 3.55 MHz. Needs some adjusting.
Have added a story I wrote about the light house activity 2010. Unfortunately only in swedish
The test setup of the oscillator starts to take form. Smoke test tomorrow.
We are building our own 80m trancievers at the radio club. Yesterday I spent the evening twisting cable and winding the torroids for the ring diode mixer in the receiver.
Picture taken this morning from the office window. A bit cold on the bike to work.
The winter have not been nice to my antennas. I discovered today that some of the radials on the vertical was destroyed. and there are some other unidentified problems too. Means I have to take the vertical down for restauration. Need to put something else up as temporary replacement. The question is what.
