I just looked at the clublog leaderboard for PT0S,
http://www.clublog.org/charts/?c=PT0S#r
And was surprised how evenly distributed QSO's per band are distributed from my
zone (CQ Zone 5), with more on 160M than on 12M, 20M, 30M, 80M.
With your success as encouragement, Bob, I will continue try
I doubt the wire broke at corner because RF is too high. Mechanical dressing at
any corner is far more relevant.
The stranded Polystealth is good stuff, will survive bends without good
mechanical stress relief much better than solid copper, but
it too will break at a corner after enough flexing
Getting away from what we are discussing now (limiters) and back to the
original question... it really is just a few bucks for a relay for a rig
(without separate T and R jacks) at the 100W level, to add separate T and R
based on the amp key line.
It's ironic that for most of half a century, th
I think we have to be careful, that innocent regular users of 160M for non-DX
and non-PT0S-DX, don't get swept up as "calling PT0S". Especially with the DX
sometimes listening UP through a broad swath of the band... and other times
listening DOWN through a different swath... we don't know who th
DL6FBL is easily the strongest, an honest S7-S8, of all the OK/OM contest
stations "bleeding over" here to the states shortly before sunset.
Wow, that's great.

I note that there's a RSGB 160M contest 2100Z Nov 17 to 0100Z Nov 18.

Unlike past RSGB/UK contest timings, this one seems to have some overlap with
Eastern US darkness. Looks like US stations can work not just UK but also any
Euro station
At my QTH, many of the local (just a few miles away) AM BC stations cut back
power a lot at sunset.
The cleanup is remarkable on my transmit Marconi. Before sunset and without any
reject filters, I literally have 50V RMS between antenna and ground. It can
light up a neon light on modulation pea
