Why said they were coax connectors for a transmitter? I use various
types of connecters for many things. For instance, my Tektronix scope
has BNC connectors for the probes. And my rigs have connectors for the
microphones.

Plus I wouldn't use balanced line in the car.

I use a lot of connectors for a lot of different things

Real hams don't use microphones. They only use CW :-)

OK - you win :-)

how difficult
it is to manufacture our own plugs and sockets, despite that BNC and N have
been around for 70 years, with SMC some time later!


Also, following on from my other post, given how good BNC's are, and how
cheap they are, instead of trying to find alternatives, I try to find
ways to use BNC's for other purposes, not hard given the range of high
quality adapters! This is NOT a wheel we need to reinvent, I think.

Especially when you can find them lying on the sidewalk.

Some years back, I came upon a pile of junk on the sidewalk, waiting for
the garbage truck. I poke around, and find a near endless number of BNC
connectors. I grab some, then continue on my way. Coming back, the rest
were still there so I grabbed all of them. QUite a weight once
accumulated.

There were a few hundred BNC connectors.

The only problem was, they were mostly male, though some female and some
adapters.

Yes, I'd use BNC for audio connectors (something others have done) if I
was going to change connectors (or building something new) and probably
more important, if this pile had included more female connectors.

The bad part is, an even longer time ago, the local surplus place had some
odd bit of plastic with one of those coaxial power connectors, 2 or 3
female BNC connectors and I think a DB-25 connector on it. All for
79cents. I bought some, but obviously if I'd known I'd be finding a near
endless supply of male BNC connectors, I'd have stocked up more in
anticipation.

That's reality, you never find the matching stuff at the same time.

And you can certainly make ladder line yourself, once you figure out
something for the spacers. I doubt anyone's ever made coax at home.

It would be an interesting exercise to conceive of the mechanism
for weaving the braid, such that it was tight onto the dielectric

I've made short lengths of rigid, air dielectric coax for UHF projects
from hobby store brass tubing on several occasions.

Well, no problem there. I just took up the suject as I saw it. I won't try to
talk to Gareth directly, he has never once responded to me as far as I know.
I suspect maybe I do not have the right kind of degree and gentlemanly air of
electromic authority for him to deign to even notice me.

Nice. A similar logic applies to knowledge in general. I once got flamed on a
forum for stating a bit of (correct) info simply because it seemed to someone
that I had picked it up from others, and they felt I hadn't contributed
enough of my own experience to their field (lasering is a ridiculously
expensive hobby, so I accept no fault there, given that offering stuff or
knowledge for free usually gets the upturned nose anyway). Also, the attitude
denies the value of all teaching, so I don't take it too seriously even when
I get hurt by it.

If we do too much, there will be someone to flame us. That same person might
be the first to flame if we do too little.

That's true. For inside a chassis. And I suppose making rigid is much
easier than making flexible coax, since you can get that brass tubing.

I've used them for DC power too, sometimes. Given the quality of the pin
surface and material, and a teflon former, this isn't a bad idea, it's likely
to handle surges better, and more safely, than many connectors intended to do
it. You mention a DB25, another favourite for me. So many pins, each can
handle over an amp, some will handle 2A each. For specialised heavy current
situations, (perhaps up to 25 A with the better ones, it can be much cheaper
to do it that way than with dedicated high current connectors, and it's far
more compact too, and the flexibity of the cable is usually better too. (And
tens of yards of that cable got thrown out during various company somputer
refits, more than I ever imagined any use for). When Maplin did a closing
deal on a bunch of metal hoods I bought 40 of them. I doubt I'll ever run out
of those, or have to spend any money on more except on occasional need for
strange angles in tight spaces.
