Re: Topband: Soldering radials?

2016-10-12 Thread Matthew King - KK4CPS
All this talk of radials makes me wonder about my radial field

The area that the radials live in has been burned in a backfire. It has a
wide variety of wire in it, mostly stranded copper.  I'm sure the
insulation is no more now that it's been burned.

I'm quite sure they're corroded now, most likely on each strand of each
wire.

The million dollar question, now - are the radials ruined?  Would I realize
better coverage if I were to replace them?

Inquiring minds want to know

Re: Topband: W8JI is bailing out of this reflector?

2016-01-19 Thread Matthew King - KK4CPS
All I know is this - I just read the "lead up" to Tom's self-removal from
the group and it didn't take me long to identify a couple of asshats that
owe him an apology. Larry? Check. Misquoting is unethical and you knew it
when you did it. Roger? You betcha. A snarky "Bye, Tom" is all you had to
say? Probably just as well.

As a fairly new and "nobody" ham trying to learn about the supposed
"gentleman's band," I've found Tom's posts very educational. I've learned
more from Tom and his website than most others.  Do either of you have free
websites aimed at educating hams new and old?  Maybe Google is broken, but
I couldn't find them. Being prolific operators I'll concede in both cases,
but what're your contributions past that? If y'all are the "gentlemen" that
I'm supposed to be working on topband, I'll go cut the coax to my measly
160 antenna now, thanks.

Tom's loss will be felt far more than whatever you two may bring to the
table, I'm quite sure.

Shame on you both.

To the rest of the list - I apologize for my impertinent behavior. I've
spoken my peace. I'll reign it in.

Wouldn't stranded wire be preferred for such a use?  Maybe I'm missing
something, but it seems that solid wire would be more prone to breakage.

 I found a great source for radial wire at home Depot where they have
 100' rolls of 14-2 packaged for under $40.  Two conductors are insulated
 and one of course is not after the easy job of striping them across a
 bench jig or simple having a second person hold a pocket knife while you
 pull the conductors apart you end up with 300 feet of higher quality
 ground radial material. 2 each  100 foot insulated radials due to the VF
 are very close to 1/4 wave consideration and the the shorter 100 foot
 bare doesn't hurt either.  This of course brings up the issue of mixing
 bare and insulated wire in any ground system so I use the bare conductor
 for other 80 and 40 verticals.  Yet the sum of the three wires is
 cheaper than buying them individually it seems.
