The Inv L FCP continues to perform.
After a nice long hot summer here which is unusal here I was on last
night around 0230 and worked K6ND, WJ3A, G4EIM. LY2OU, UY0ZG.
While operating I started hearing at regular intervals somewhere of in

Hello Nick,
nice to read you here and nice to know that you are on the way to put 5X on the
TopBand.
See you on the air, to complete our band slots on 80 and... 160.
I do not give you any tech-advice because am novice too :), just my GL 'n see
you there.

DX'ing between
The old inv L and on the ground non-uniform and erratic radial system
did not cause this issue so do I conclude that the effective radiated
field from the FCP Inv l is that much stronger?
Hi Frank,

Nick,
A 50ft tophat vertical is a good antenna. I would suggest that you put down
as many 135 ft long radials as possible, at least 25. If this is not
feasible, put down as may random lengths radials as you can.
The problem is that it is a vertical antenna and will be noisy,
particularly if you
When I first installed my 3/8 over FCP here, it was PRE isolation
transformer. Given the unfortunate 424' length of elevated Wireman #554
450 ohm window line back to the tractor shack for conversion to 50 ohm
coax into shack, it was very heavily coupled, as explicit modeling would
later reveal.
If you cannot use radials laid on the ground, you could use at least two (ideally
more) elevated radials loaded with inductors or the relatively new Folded
Counterpoise (FCP);bhowever, the FCP requires a special antenna matching
circuit.
Huh? No matching network on my FCP antenna.
I have been v QRV from 5X in past 5 years. Returning this Oct for 8 weeks
and considering how best to get 160 on the air as it is the only band I
have not worked and reckon there must be un-met need!
I go to work (pro bono) at a community university so not a dxpedition but
solo so plenty of
Hi Nick
Like many others, I am very glad to hear you will be QRV on Topband.
A few suggestions if I may:
Operating on Topband has a bit of a learning curve. Not steep, but a
few things that may help:
Code speeds tend to be more moderate than other bands. On 20, a
DXpedition can zoom along at
The last information I had was this 160 meter DX window was no longer in
use as a window by a international agreement of amateurs. It previously
restricted North Americans from calling CQ DX in it, while allowing other
countries to do so. I was one of the Americans calling CQ DX run out of

While looking for something entirely different, I came across this. I wonder
if anyone has this book?
Grant, KM5KG, is one of the most experienced broadcast engineers around.

Grant claims:
A New Book from Grant Bingeman, KM5KG
112 pages 8.5 by 11 inches
On the surface this seems to agree with what I find. There are dozens of
ways to have about the same results. I wonder what Grant has in the book?
I recently purchased a copy from the ARRL and it's well worth the $20 price.

Out west in flyover country we rue the day. Tom is spot on. I too stay
out of 30-35 for CQing so my western brethren can potentially hear
something. Very unfortunate to have the 30-35 window, which many DX
stations use, clobbered by a very few thoughtless W CQ'ers.
