    Im 7 years late! but excellent video. I want to build a remote ATu for 13m long( 2x 6.5m al tubes)rotating dipole. Switched from the shack using larger inductors to dissipate heat and higher Q. Maybe for 1kw ssb. I thought of doing same with thermal camera. I will also measure loss through ATU using a reactive dummy load in a calorimeter.

    Maybe some day an even lower frequency can be used. And who knows, perhaps even going below zero Hz, negative frequencies. Not mathematics is the final fronter, bit it is the imagination that is limiting us.

    OK1FIG, I WANTED TO COMPLIMATE FOR CW KEYER, IT WORKS GREAT. I HAVE A QUESTION FOR YOU. FOR HABIT, I USE AS A WIN TEST PROGRAM BUT MANY YEARS, YOU CAN USE YOUR CW KEYER ON THIS PRG. I HAVE SEEN THAT THE SPEEDS ARE DIFFERENT I ALSO ASSUME THE PROTOCOLS. CAN THEY BE ADAPTED ??????? THANK YOU

    • @petrmaly1597
      @petrmaly1597 4 года назад

      Thanks for your feedback. Before, I used WinKeyer. I developed Spider Keyer in order to get rid of the design flaws of WinKeyer. Therefore, obviously, I don't have much reasons to emulate back the behaviour of WinKeyer. Either use HamRacer loging software for which Spider Keyer was created, or try to convince the author of Win-Test to implement support for Spider Keyer. The protocol is simpler than the one of WinKeyer. All the technical information is available on my web pages.

    Hi Petr, have you thought of injecting DC into the coax to avoid using a separate control cable? I'll appreciate your thoughts on this.

    • @petrmaly1597
      @petrmaly1597 4 года назад

      I have. It could be technicaly simple. However it would mean another box between PA and the coax cable. “Remote” in my case means 6 mtrs or so. It came simpler to me to draw a separate cable for the control. Petr

    • @petrmaly1597
      @petrmaly1597 4 года назад

      Díky za názor. Radioamatérská komunita je poměrně malá, díky tomu i sledovanost videí není nic moc. Až si někdy říkám jestli má smysl v tom pokračovat. Tohle pomáhá. Co se týče linků: víc lidí sleduje moje videa spíš ze zahraničí, a tam jim třeba link na český e-shop není moc k užitku. Ale mohl bych dávat víc info do popisu a komentářů, to je pravda. Díky za tip.
