Title: Question: Best propagation on 15 MHZ from Europe to America
Post by: CWR on August 13, 2013, 1601 UTC

 Hi folks,

we just put up an antenna for 15 MHZ and would like to know the best time to reach you over there in America. We are on low power only, but we we like to try it.

Thanks for replying in advance

Hi Chris,

Try using the program VOAProp which is a nice interface to VOACAP.  It provides graphical displays for propogation conditions for the HF ham bands based on current solar conditions.  For 15mHz the 20m display should be close enough...

I can't speak for those south or east in North America; but I generally have the best luck working Europe  from North West North America on 14mhz. from about 2200GMT to about 0200GMT. Low power should be no problem, although AM and low power can be a tough combination.

Check out the Aussie HAP and Ionospheric charts for assistance with frequency selection :)

2200 to 0200 works here in the east too, at least during the summer and early autumn.  This is arguably also the time when most of us are able to turn on our radios to listen.
During early winter, 2 or 3 hours earlier will likely work better on the east side of North America (maybe even earlier for the Northeast).
