The first state-side QSO on 160 from Desecheo (KP4AM/D) (after a couple of
Caribbean stations) was with K4IEX on March 5 at 0256 on CW. Then followed
W4DR, W2QD, N4WW, W6RW, W8LRL, AA4V, K3VA and W4PZV. Number 22 down the same
log page was none other that W1BB. The first Canadian was VE3BMV
That sounds like no-ox on DC plant connections. You'll find after years and
years that the copper will still be shiny and new looking in the
grease-protected areas. The idea is to keep out oxygen so that the connection
doesn't corrode since the corrosion is what increases the resistance.
Herb, N0VA/KP2 is also in the log.

Helpful advice, Tom. Thanks. I've always worried about using silcone
grease
on connectors. I understand it helps seal the connector, but my fear is
that
it could interfere with the electrical bond. On the face of it, getting
non-conducting grease on, e.g., the center terminal of an
I worked for many years in the Xray service business.
We use silicone grease in the plug in Anode and Cathode plugs. If
the connectors were not coated with silicone grease, The connectors would
explode. The cathode connector had 1/2 the tube voltage and the filament
voltage.
The filament
On 160/80 meters how much RF power can RG8X coax safely handle and is 8 or
10 turns on a 6 diameter piece of PVC pipe sufficient for a feed line
choke. Run is about sixty feet long.

RG8X can handle more than the legal limit on 160.
I think you would be better off with a ferrite core choke. Look at

The choke we use is described (and photo) at

Yes. Also see the Choke Cookbook in k9yc.com/RFI-Ham.pdf 16 turns of a
4 ft length of two parallel #12 THHN conductors connected as a section
of parallel wire line makes an excellent choke
I almost put a link to your info in my previous e-mail, Jim. That's where I
got the info to build the choke I use.
