Nice, Hugh.  I hadn't considered that the lattice network would function 
below a mean conductance of 0.3 mhos.

Steve has made an interesting discovery.  The de-ionizer plate he has
identified is the secret behind the "Electronic RustProof" process that exists
in all vehicles containing a lead-acid battery.

The effect is that connecting the negative battery terminal to the metal frame
of the car, all rust molecules are then transported from the surface of the car
to the battery case.  The excessive amount of rust accumulated in the battery
box is proof that the system works.  In those cases where the rust is not
transported to the battery box, it will occur on the surface of the car at a
point determined by the conductive latice network established by Ohm's Law.
Once started in that area, the molecular movement of the rust will then be
concentrated in that area.

That was a great discovery, Steve, we need more of these scientific discoveries
to answer the physical mysteries of life.

This is all probably fine for amateur applications (all we care about

Sorry, WHEN I was the Electrical Officer, I "owned" the battery. 
I presently have access to neither submarine, nor battery (thank god!).

If it makes any difference, there was no concrete in the battery
compartment :-))) There were enormous bus bars, 5 psi air manifolds, an
"explosion proof" fan  and bakelite "deckplates" but no concrete. 

More: leakage thru traces of acid droplets were a big deal. DC bus ground
      readings could get as low as 100k ohm between the DC bus and
      ship's hull. Then there would be a battery-well cleanup and the
      ground resistance could be brought back up to 2M or so.

of Nebraska ($12 !!) that was supposed to be the real thing, and the

it doesn't look good next to other Collins equipment.

  Didn't the whizz kids at FCC bring this on themselves when they designed
 incentive licensing calls that gave more emphasis to  *license class*

and beating on the FCC for overly trivial matters is a good way to win the 
battle and lose the war.  not that you should prostrate yourself before you 
talk to a staffer or refrain from criticizing their work.  

i don't know if beating the FCC with Congress is a good idea.  it seems like 
that should be reserved for when there is a Real Important Issue to address.  
do you really want the same people who ran the House Bank and Post Office to 
micro-manage the amateur radio decisions of the FCC?

i've always thought that an interesting mag article would be a treatment of 
the petitions that show up at the FCC asking for things that are already law, 
asking for things that cannot be permitted, nets to be given ownership of 
frequencies, number of petitions that misspell "amateur" and so on.  I've heard
speeches by the FCC chiefs on this and it's usually good for a laugh - and i 
would think the League would be doing something like that (maybe every couple 
of years) to support their "don't ask the FCC" campaign.

Maybe Fred Maia would do it in CQ...

Pretty sure Wayne G. could go for a dozen pages on this alone (esp. since he's
sold off some of the mags again..)

Why does the length of the transmission line make any difference 
in the SWR? It might make a difference in apparent SWR, but actual 
SWR (measured near the antenna) will not vary with the length of 
transmission line.

Now, at the ripe old age of 32, I have gained a neighbor who is

Thomas-

I think most hams will agree that MFJ is not the most expensive product. 
They seem to know how to cut corners.  I suggest you contact them about a
modified version of the phone patch, since competitive models might cost
much more.

When you go into production, you may still find MFJ to be an inexpensive
place to do the fabrication for you.  It might be worth your time to find
out.

Well, this is half of the answer...
The NC in BNC & TNC comes from the last names of their
designers.  The other half of the answer, which I don't
have, is the actual names...  Anyway, Mr N and Mr C, whoever
they were, designed both connectors.  B is for Bayonnet
and T is for Threaded.  The N connector was designed by Mr N
alone; I don't know for sure but I'll bet that Mr C did
the Type C connector.  It's no miracle, then, that
BNCs can be fit to type N connectors (just shove 'em

Well, here we are again ... :-)

For any who have read my earlier post ... nothing was meant by it to discour-
age newcomers; these are only observations of mine ... and nothing major 
(mostly) has come of such things as not knowing what one is doing at first,
cuz eventually, everybody gets the hang of it if they stick around long enough.
:-)

First off ... to the feller who sent the questions, Welcome to ham radio!!
Same to all you others that are new, whether you've made that first contact 
or not. Yeah, the first one is really nerve-racking, but well worth it. But
again, that is another story.

Now ... Probably a good catch-all sort of piece of advice is this: 

Just get in there and do it!! (After listening a little while first) :-) 
Doesn't take much ... drop in your call at a nice break, or make a call your-
self. Mostly, there will be nice people to welcome you. Sometimes not, but 
then, you have not-nice people everywhere. For myself, if I hear a new call,
I try to be neighborly and such to the new ham. Meet more people that way.

If it makes you feel better, have someone walk with you through your first 
few contacts, or arrange a contact with someone you know. If you don't know
anyone ... umm ... Well, that might pose a problem. :-) All kidding aside 
though, most people would be more than happy to help anyone out with such 
a thing. 

To all of your questions, aside from those involving autopatches--which are 
pretty gray anyhow--the thing is that you should just have a listen around
a little to get the general idea of what is expected--applies for nets more
than other things, I think ... but just listen, decide what you like, and 
jump in! The water is fine! :-) 

If you're in the Austin area, try out our 145.21 repeater. There is usually some
one listening, and usually something stimulating, (or at the very least, fun)
going on. 

Again, welcome!! And enjoy ham radio to its fullest--something that isn't hard
to do really, considering how diverse ham radio is, and how diverse ham op-
erators are ... once you find your niche, there you are.

73 and good luck in the compost!! :-)
