You don’t have to be a member. Everyone is welcome!

James Kretzschmar AE7AX will be traveling all the way from Cheyenne, Wyoming, to discuss homebrew construction. The presentation will feature his recently built homebrew 40-meter CW transceiver. The 10-watt transmitter section uses six switched crystals for frequency control. The seven-transistor direct conversion receiver utilizes three of the semi-conductors for the mixer/detector, two for the oscillator, and two for the audio amplifier. The presentation will include discussion of schematics for the rig, construction techniques, and the joy of homebrewing.

Our meetings usually end with an optional luncheon at a nearby southeast Metro area restaurant for a lot of fun chat and chow!
