Some people were curious about what the letters and numbers meant when I was talking, so I just wanted to tell you what they mean: The first thing I say is my callsign: KJ7NLL. Then, I say my ham grid square: CN85. Finally, sometimes I say CQ CQ CQ, and that means that I am asking to talk to anyone on the radio. You can get your callsign by taking an amateur radio test.

Push to Talk Circuit for LNA (without a relay!)

We show a push to talk circuit to use the ACC1 port on the Icom 9700 radio to turn on and off and LNA. This is designed for an LNA, but could work for a power amp if you use a P-channel mosfet instead of an N-channel mosfet. Register for DAC: www.dac.com/

    May I ask, are you using the same 2m helical antenna for both transmit (~145.99MHz) and receive (~435.8MHz)? Or do you have a separate antenna for 70cm reception?

    • @KJ7NLL

    It's probably more feasable to build a cross-dipole yagi "arrow" antenna at 2 meters though. That will still have the circular polarization while also being much quicker and easier to build while also giving higher gain.

  • @OtherPerson101
    @OtherPerson101 Před 2 měsíci

    As a teenager myself, I find it amazing this kid has the proper tools and resources to build such antennas. While I've build my own share of crazy contraptions (including a cardboard satellite dish), they were all crudely built with stuff I scavenged around the house. Congrats on actually having the right tools for the right jobs!

    Very impressive work. The use of the battery contacts to jump between the PCB's is an ingenious idea. I have always used pogo pins for such tasks, although they tent to be a bit to pointy and can eventually scrape the plane down to the dielectric. Lots of very good thought put into this design.
