I needed to update some of my old 40M CW gear and try some new stuff. I am finishing a 40 CW transceiver which began as a SSB rig last year. For the RX I use some of the ideas from the K2 for the front end and some of the KK7B direct conversion RX ideas for the product detector and audio section. The RX covers approx 7 to 7.100 MHz. I have completed the transmitter section. It is a 16W mixing type TX. The carrier is 9.216MHz and the LO runs 2.07 to 2.216MHZ. The 1st board is the carrier, mixer and triple tuned band pass filter. I used my HB LC Tester to build the filter and some other test gear from EMRFD to measure outputs as I was building each stage. It obviously built ugy style. This is a rough copy of the schematic for the above circuit board. Pretty classic circuit and something I have done several times.
