Recently shortwave free radio station Channel Z Radio conducted test broadcasts using three different transmitters, all on the same frequency with the same antenna, a half-wave horizontal dipole cut for 6925 kHz, mounted about 40 feet high. As described in a recent article, this setup should be ideal for NVIS or regional operation.

It was interesting to see how closely theory predicted real world performance for signal intelligibility and propagation...

Really nice comparison & interesting article. Yeah, I always really enjoy the Channel Z DX tests, so it's really cool to see the side-by-side comparisons (especially because I missed this particular one).
Thanks for the article!
