You can work the world with 14 watts!

And then there's the water supply/arteriosclerosis/atherosclerosis thing to consider.

Amazing what porcelana can do.

I wonder if they ever do hf moonbounce with that thing?
Like how haaaaarp did on 40m cw? I got a demo of it somewhere.

A number of antique radio aficionados use a small am tx to send old time sigs to their behemoth zeniths and philcos, so don't be surprised if/when you find them. They typically look for the clearest band segment and might not be using a strictly part 15 antenna or power level.

This is ossum.


Also, one of the wifis here is named "FBI surveillance van".

I dare you to find a antenna more efficient than the good old dipole.
I'd add some ferrites to each end of the coax, make sure that coax is in good condition, and make sure there's nothing near the antenna that can detune it. Also look into "cobra" dipoles, they add linear loading to the mix and can be of benefit. Also consider propagation, if you don't have it, you're not going to get out.

And a qsy to 337.3 w/modem traffic @ 1630 22Jul17. However, there may be more than one neacp/tacamo up at a time and one can fade out while the other is still in range, but they usually have about half the country between them in distance.

I ate a few Monarchs in crysalis today, makes for a delightfully crunchy coating to a juicy center!

How did I know that was coming?



They're chitiny good!

New freq, strong sig with ssb voice on orderwire alpha, must be close.

A hint on catching these guys is to use am mode. The main carrier is at the center of the working freq and will always stop the scanner in am mode on this signal. If you scan with wide or narrow fm the scanner will typically blow right past the sig on a default squelch setting. Once you find the sig, lock the scanner on freq and then open the squelch so you can try nfm and wfm modes to see what you get. I typically only use am mode however, using slope detection via the am modulator on the wideband (60khz) fm signal thus missing out on most of the signal as most am filters in typical scanners are only some 15 to 30Khz wide, but am allows you to 1) pick up the signal easily even when weak, and 2) to demod the orderwire pair at the carrier of the fm signal. Well, since you're using am and the orderwire voice traffic is always ssb you're listening to ssb with an am demodulator, but you can still follow along with some difficulty. A sdr system will be much more versatile.
