WA5RR Adventures in Ham Radio

I will attempt the 222 MHz and Up Distance Contest for the first time as a rover this weekend. Here is my planned route: I will start in EM04 at the I-44 Exit 1 and then swing over to EM14. Next, I will head to EM13 and end the route in EM03. As for now, I only plan to be out on Saturday but anyone who needs EM04 or EM03 on Sunday is welcome to email or call. Bands available are 2m (can be used for liaison frequency), 1.25m and 70cm. All modes. 73, Korey-WA5RR/R

     I posted a few weeks ago about my plans to use some inexpensive Doppler motion sensors as 10-GHz transmitters. At the time, I wasn't entirely sure on how I would transmit with it. To do so with this module, you modulate the input voltage and can use an audio input device such as a computer, MP3 player or something similar.      Surfing around a Facebook group a few nights ago led me to find the Four State QRP Group. On their site, I saw a Super Simple Code Practice Oscillator. It has audio output to a small speaker and a rudimentary key built onto the circuit board. Eureka---this gave me an idea.      The SSCPO will lose its speaker and I'll replace it with a 3.5mm audio jack for output and forgo the key switch and install a connector for an external straight key or keyer. With this setup, I can use the audio output to connect to my HB100 transmitter to provide the required modulation. As a bonus, I can also use it with my Radio Shac...
