Yes Gary, After blowing then away in a CQ 160m Contest by 1m points I
figured it was rather an expensive lesson they learn.
I was using my 51ft top loaded vertical and a lot of wire under it. 73 Clive

changes with latitude and time of day (or night).

As I recall
My comments follow on three topics that have been brought up,
HFTA - It can import the elevation angle files generated from IONCAP/VOACAP
that Dean N6BV produced. HFTA does not have an ionospheric module in it. And
yes, the files only go down to 80m because of IONCAP/VOACAP limitations.
How strong of a signal can that enormous Yagi radiate into the USA on 160?
I have never heard them.

Radio Arcala - I have always believed that a horizontal antenna on 160m at
very high latitudes would generally be worse (note that I didn't say always)
than a vertical due to the effect of the Earth's magnetic field. How

As I recall they never blew up the receiver here, unlike TF4M, GM3POI, and
others in that direction from KL7 who were consistently available during times
of low absorption over the N Pole.
Then again, who knows what antenna array they were using or the ERP when heard.
I'd still like to know
I was regretful enough after installing a tall tower and using wire
antennas. At one point I had a two element wire dipole phased array up at
maybe 250-260 feet. When it fell down in an ice storm, I was relieved I
didn't have to take it down.
I had a 110' Aluminum Heights fold over had a
