The One Watter QRPp Transceiver Kit

  • K7QO's Intro to Kit Building Presentation. August 23, 2015. Presentation I did for local club. Get me in front of an audience and I get kinda crazy and silly.

    Exciting news. A new kit from Kits and Parts. Diz, W8DIZ, has a new QRPp kit for $44 coming out in a few weeks. He is taking preorders at the present time. See his web page at http://www.kitsandparts.com and look for the OneWatter link on the left hand side. Here is my build of the beta version to help out finding minor errors in the PCB and instructions. I have done an almost complete job of detailing how I build it with my build and test by section methodology. May work for you. I put the complexity of this kit on the same level as the old SWL-XX series from Small Wonder Labs. It works well. See my challenge to myself to work all states with 0.95W on 20m. Been there. Done that. Have the award to prove it. Did this when I was in Dallas TX and gave a presentation at Dayton with display of all the QSL cards. Enjoy.

  • K7QO's Build Notes on the Kits and Parts One Watter Transceiver. August 20, 2015. Updated for errors.

  • MFJ-840 2 Meter Wattmeter Video. August 22, 2015. Here is a hints-and-kinks from K7QO on how to adjust you 1W using a simple wattmeter from MFJ for $29.95 from the web page at www.mfjenterprises.com.

    OK, first goal is to get WAS on 20m with 0.95W output. Using only the One Watter, a dipole made up of two MFJ mobile antennas in a dipole configuration at 6m altitude above ground in an antenna restricted HOA campus. Power supply will be a gell cell. Here is map of the results thus far. Start date is July 30, 2015, the day the xcvr was completed and tested.

    Miles are generated by N3FJP logging program and I see that they are totally wrong. Will correct later today, Sunday 08/23/15.

    The NorCal QRPp Journal Archives

    In talking to Doug Hendricks, KI6DS, on the phone I find out that the back issues of The NorCal QRPp Journal have disappeared from the NorCal Home Page. Time to put them back online. Doug gave me permission many years ago to give my scanned copies to the club to be put online for permanent access to all QRPers world wide. So here they are gain for your enjoyment. Doug spent 11 years doing this work with the help of many contributors to the writing.
