    That's cool Bob - I like how you used a 567 for that. Great application. I try to do it by ear, but I miss sometimes.... Reminds me of reading light years ago in the Navy (I worked in aviation but could read the light the signalmen used - my fellow techs would always ask "What are they saying???").

    I built the QCX and it is working nicely. I built the QMX and am having issues with it. It is too tiny for my 81 year old eyes. My next project will be the QCX+, problbly for 17 meters. Thanks for the video.73's. Mike WA8UOC

      I built the QCX plus for 160m, it is a much easier build than the mini....I stuffed up my first build of the mini (probably similar to QMX size and difficulty). The QCX plus is basically the same as the mini but just more thru hole rather than SMD parts - so YES great rig and less stressful build!

    Bob, try pushing in and holding the tune knob in and turn it and see what it does. Carl

      Thanks Carl I see that it is printed or actually etched by that knob tune ,rate and MESSAGE So many features in this little wonder
      and more to check out and learn as I type this I remember going to Electronic Supply in Roseland Indiana just north of South Bend to buy a couple of Raytheon CK722 transistors in the 1950's when they were first available for $1.00 each to make a regenerative
      Broadcast receiver I most likely rode my bicycle and now its back to the future and at age 79 I am still into
      Ham radio and learning with electronics and still excited about it ... 73 and good DX ... Bob

      @@robertsumption1243 Hi Bob. I am almost your age and was interested in electronics since I was a kid. No place to buy any parts then until Radio Shack moved close and I was able to get there floor sweepings junk. Back then I lived near a Navy base and could get some ARC receivers. I even got them to work. I am envious of you. I grew to love Heathkits and have about 15 of them at this time. I have only one Heathkit that I couldn't get to work in all modes. So 73 Bob and I look forward to your next Video. Carl AB1ZI
