Hmmm...lemme see...we're faced with the possibility of having a lot of newcomers with little or no practical experience WRT radio wave propagation on the HF bands, and thus little knowledge on which to base selection of a frequency band on which to begin making contacts at any particular time. Back in the early days of my HF career, I figured that if the band seems empty, well either propagation is out or everyone's asleep or at work or such. In any event, there's nobody to qso with, so check other bands. After a while, one figures out that on say ten meters, you can (when the sunspots are in) talk to Texas from NJ, but not Ohio. That the coverage looks more like a ring instead of a disc. Which also means that the ham in Texas can hear a ham in Ohio that you cannot hear. Thus you could QRM a Ohio to Texas QSO while doing a QSO from NJ to California. Thus you should realize that the Texan isn't talking to himself, but to someone you cannot hear. And QSY up or down a little. But say you're using a kilowatt linear to QSO from NJ to California, and the Texan is only using 50 watts and is S1 on your receiver and thus you don't know that he's there. BUt things like this happen, and it is understood that it is not malicious. |

Often that is the clue to what's happening, or about to happen, on an otherwise seemingly dead band. Sometimes when you tune around carefully, listening for any hint of signals, you'll start something - you hear a very weak one, peak him up with your receiver filtering, whatever you have to work with, listen long enough to ID him and where he's located. If he signs off with the station he's working, and you've tuned up, you give him a call. If he's copying as well as you, he answers and suddenly you've turned a dead band into a QSO. More often than not, others will hear you two in QSO and next thing you know they're either calling in tailending you, or calling CQ nearby and drumming up their own contact. When you next tune around, there'll be several QSO's going on on the "dead" band. This scene plays out far more often than you would think, or used to back when HF experienced hams were the norm rather than the exception. Sure is worth trying, anyway. Dick |

Dick One more hint-some of the best DX contacts I've ever had occurred when I called CQ on a "dead" band. You get to work the rare one who answers without the "benefit" of the hounds, no pileup, no QRM, at least until enough others hear you working him to draw a crowd. |

Wish more people thought that way about 6 meters!
