I've made a #HamRadio #AntennaExperiment decision. I'm going to switch my #ShortyVertical from #TopBand & instead work on it for #80meters ...& here's why:
My #TuneATenna could only get to the top edge of 75m because of the size of my yard. But I actually have some friends who are on that band regularly. It'd be good to be able to do 3825kHz AM without a tuner.
And my #DxCommander only goes down to 40m. If I get the shorty to work, I'd be set for winter.

The carbon fiber mast that I'd hoist the tip of this vertical to is approximately 55' AGL. So a #MeanderLoading section near the ground only needs to eat up a half dozen feet of element length. This should be possible with hoops about a foot in diameter. A much more manageable experiment.
@kelvin0mql Heeeeey, I just happened to come into a 75m AM transceiver recently! :P
I guess it's time I built my first antenna to see if we can get a QSO.

Transmitter.
It does not receive.
That's why it has that 2nd SO2398 that's switched to ground during TX, so some other receiver can RX from the same antenna during the times you're not transmitting.
Like an SDR, for example.
Heck, you could also use a web-based SDR for the RX side, and possibly also hear yourself.
Yeah, hook it into a dummy load, and the nearby SDR would pick that up beautifully. Rock on.
@kj5amz Rock? As in Crystal?
