01/29/2009 | AA4LR Finally completed my homebrew station with a 40m five-integrated circuit receiver. I had started it last year, but didn't finish in time for SKN. Used the same two-tube transmitter from the last couple of years. I added a T/R relay so that it was easier to switch from transmit to receive -- and it also eliminated the risk of pumping RF into my K2/100.

Only had a limited time to operate on New Years Day. Made six contacts using five different crystal frequencies. It was fun pumping the old key and making contacts. Each QSO was unique and interesting.

The receiver added a lot to the experience. Had to make two mods to the receiver while operating. First, the BFO frequency was off, making the CW pitch too high. Second, the AGC time constant was far too long, making the recovery time after switching back to receive. 40m CW band sounded really alive during SKN.

I've put the details for my setup on my blog. Read about the receiver here:

Great fun! Can't wait to break out this pair again next year. -- AA4LR
