    This is what ham radio is all about. Nice job.

    Very cool! I wish there was more microwave activity around in Northeasters Ohio, but everyone's too busy on 2 meters or HF. I'm probably the only one in my area interested in it tbh.

      Are you aware of K8ZR, KB8VAO, N8IUP and W3IP ? I know that the first two stations are active on 10, 24, 47, 78 & 122 GHz, 10 GHz for the latter two.

    Very interesting. No one around here even wants to do anything on microwaves

      That's a shame. I'm fortunate to be in the lower Great Lakes area where we have relative high microwave activity between the Greater Toronto area operators, a crowd in the Greater Rochester N.Y. area and several other American stations around the south shore of Lake Erie.
      Keep in mind, there's some truth to the old adage... "If you build it, they will come."

    Excellent stuff! Hope you can extend the distance, with those signal strengths it should be feasible. I need to make a batch of 76 GHz feedhorns urgently! Neil G4DBN

    This is so cool! Do you think some of the watery-ness in the audio could be phase noise in your down conversion? 78 GHz… wow.

    • @radeohedca
      @radeohedca  Год назад +2

      Possibly. The other station thinks that his OCXO may be a bit flakey so he's going to check into it.

    is there any practical reason to do this? couldnt 144mhz still make that connection pretty easily?

    • @radeohedca
      @radeohedca  Год назад +1

      Yes, just like a cellphone could.
      Everyone has their "thang". It's technically challenging and especially so as you move up in frequency. Free space attenuation increases as you go up in frequency so you don't get the range that you do on the lower bands. We endeavor to push the conventional limits of "line of sight" communications and take advantage of different weather conditions to extend our personal best distance records. If you want easy, use 144 MHz. If you appreciate a challenge, try the microwave bands.

      @@radeohedca thanks for the info, ive considered trying higher frequency stuff before but never really got into it, too expensive and nieche, but it definitely seems interesting

    Is Kevin still running the horns on his 78 GHz system?

      Kevin was also using the same 12" MT799002 dish.

    What bandwidth did you get?

      Please elaborate... I'm not sure what you are asking. We used single sideband analog.

    The Bandwidth 😧

      We usually use CW but signals were so strong we went with SSB.
