[GreenKeys] Response to Kevin Phillips Mar 20, 2022

[Kevin H. Phillips]

	Tom,


	 


	Thanks very much for the information and the photos.  Those are some
great ideas.  Having one or more permanent loop supplies is
definitely on my wish list.  I am working on a dedicated radio shack
which I hope to have nearly finished in the next few months.  I want
to have ability to connect my working machines and be able to connect
"new" machines as I work on them.  There was an HD3030
that came up on eBay recently but I didn't get it.

	> Kevin,

	> You do not need to get internet out to your barn to work on
Teletypes.

	> All you need is to get a loop out there. I do not know what your

	> distance is. My Radio Building is about 100 feet from my house.

	> I bury thin wall plastic water pipe to pull wires through. I like
them

	> underground where they are at least partially shielded from
lightning

	> surges.

	>

	> I am lucky enough to have three of these surplus 16-jack panels.

	> Each horizontal row is one loop. They are all 2-conductor jacks.

	> I wire them together with cat-5 so each row jacks on all are the

	> same loop. I also like to always make the tip positive.

	>

	> Before I got one cleaned , painted and re-wired for the cellar, I
used a

	> home brew two loop panel. Again, each row of lacks was one loop.

	> I wired it with 4-conductor stranded thermostat wire from eBay.

	> In addition I had a 3-jack panel on a local loop supply for
testing.

	> I constantly use my meter mounted in a Lowe's plastic electrical
box.

	> It can be patched to any loop.

	>

	> The 16 jack panel has 2-circuit jacks. The next two home brew
ones

	> are 3-circuit jacks. I also make them with 2-circuit jacks and
insulators.

	> It is a nuisance to mix both types of jacks. It is better to decide
at the

	> outset which you want and stick with it. Of course the 3-circuit
jacks

	> are safer, but that may mean changing the plugs on all your
teletypes.

	> And in my case I could not use the 2-circuit 16-jack patch
panels.

	> So I have a lot of adapter boxes and cables.

	>

	> The final step is to have the TU(s) where you have the internet. I
have

	> two

	> Heathkit HD 3030's. The bottom one (connected to the bottom rows of
jacks)

	> used to be ITTY news. It is now on my news stream. The top one
(connected

	> to the next rows of jacks) used to be Autostart. It is now my TTY
Artwork

	> stream. Since the computers that generates them are right here, I
grab the

	> streams from the headphone jacks.

	>

	> It is not a big deal to pull two streams from the internet with
one

	> computer.

	> if any one is interested, I will explain it.

	>

	> It is also fairly easy to pull wires through long pipes. A friend,
who is

	> now

	> a silent key, showed me how to do it. I can explain that too if
anyone is

	> interested.

	>

	> Ii hope this helped someone.
