Title: Pirates on 13900 kHz range?
Post by: jordan on February 17, 2015, 1959 UTC

Since pirate broadcasters use the 6900-kHz band, right below the 40m ham radio band, are there any that commonly use the 13900-kHz band that is just below the 20m ham band?  That might work better than 6900 during the day.  Or is 6900 good at any time of day?

A few have used it over the years with good results.

The problem is that pirate listener's are generally frequency sitters. They'll tune around the popular frequency of the time, but that's it. Even with the advent of SDR's most listeners are content to scan from roughly 6770 to 6970 khz. these days.

The pirates tend to go where the listeners are and vice-versa.

It's always fun to screw around off the established frequencies, especially now that we're in the days of the interwebz and much less crowding on the SW broadcast bands, just to see how many "WTH?" reports you'll get via email from random SW listeners.

In answer to the question...

I tried 12 MHz once during the day near the height of summer... and most of the listeners were unable to hear it, in the larger "blackout zone" around the transmitter site, that gets larger as the frequency gets higher.  Think I had one logging on that frequency from Florida, and that was it.

The 6.9 range will work during the day, especially in the winter, but the maximum range will be less, and signal strength lower-- but that can be somewhat balanced out by lower noise.

Is murphyslaw similar to coleslaw, only made with murphys?

It's the same as coleslaw, only with too much rat in it.

I've been told Murphyslaw is made by an aging rabid bunny.

How he does it without opposable thumbs is the real mystery.
