KX-170B/KI-214 Connectors
Jim Weir
KX-170B and a KI-214. However, the connectors on these units are somewhat of a
mystery.
On the KX-170, the power connector is specified in the manual to be an Amphenol
26-190-42 and I'm reasonably certain that I can pry one of those out of some
distributor's stock. However, if anybody has one floating around, I'd be more
than happy to make whatever deal you might want to make for it. However, the
two RF antenna connectors (Nav and Com) are identical and appear to be the same
SIZE as BNC. However, they have no locking ears and I suspect that the
specified connector (TED 9-10-12, which I have never heard of) have spring clips
of some sort that will grasp the flared end of the connector for security.
The KI-214 has me totally baffled. The power connector looks like the
grandfather (or maybe a funny uncle) of the computer D-connector, but has FOUR
rows of male pins...a row of 6, a row of 7, a row of 6, and a row of 7. The
keying mechanism on the ends of the connector is a male on one end and a female
on the other end. There appears to be a latch for a hood to snap on to. The
glideslope RF connector looks like a lilliputian BNC. If you could shrink a BNC
by about half, you'd have this sucker nailed.
Any help on any of these connectors, manufacturer, source, etc. would be
certainly welcome.

Jim, these RF connectors are exactly the same as a MALE bnc without the
"twist-lock" part. They are attached to the radio mounting tray only,
with a little bit of mechanical play so thay they'll line up with the
flared end on the radio. In a pinch, dremel off the twisty retaining ring
of a male BNC and clamp the antenna cable securely after stuffing it into
the back of the radio. (My DME lived like this for almost a year.) I will
try to dig up a picture of the TED part this weekend, so at least you'll know
what you're looking for.

That 4-row unit sounds like Amphenol to me. I'd look at their series 17HD.
Are you sure that it's a D-Sub? I seem to remember that these had a greenish
plastic substrate and were more square than a D-Sub. I can't remember the
series off hand, but I think that they were Cinch. Do they look like
the connectors on the back of a Cessna RT-328 radio? (I've never seen
a KI-214.)
The RF connector could be anything, but I'd bet SHV, MHV, or RFX. Try
looking at www.pasternack.com, they have everything you could immagine
in RF connectors and some you probably couldn't immagine. Their printed
catalog has 2 or 3 pages devoted to RF connector identification, with
dimensioned mechanical drawings and all. Perhaps you could find the same
on their website.

Aha! I found it! I was looking for the KA-25 that I pulled out last year.
It's got a similar connector to the KI-214, except it's 6-7-6 (three rows).
It's made by Winchester Electric Inc. and mine is a part# MRE 20 H (it's
not clear if that's for the backshell or the connector.
I've never heard of Winchester Electric Inc.

Jim, have a look at http://www.winchesterelectronics.com/products/rp/rp.asp
and have a good time trying to find one at a distributor (did someone say
"engineering samples"?).

for years. Very common. Uses a snap ring to hold the connector in place.

Not quite. They are flared at the mouth of the connector to guide the male
connector and provide a lip for the spring clip to hold on to.

As you noted in a subsequent post, they are Winchester. Your comment was quite
correct in that "engineering sample" is damn near the only way I'm going to get
one of these in this century.

Pasternack was my first shot and nothing on their web pages (or in the little
catalog I keep on my shelf) resembles this little hummer. I doubt King invented
a connector, but I'll bet they got themselves an orphan.
Mike Ferrer
has them in their consumer catalog for $22. They wholesale for around $13.
I have a few in my shop if you can't find any locally. The part number you
originally mentioned has, I believe, changed to 9-30-10. Same connector.
TED is the mfr.

Are you talking about the little pint-sized BNC lookalike on the glideslope
receiver, or the snap-ring mount full size BNC on the back of the navcom? I
think we've got a good handle on the navcom; it is that little half-size BNC on
the glideslope that I searched Pasternak on and came up dry.

Jim,
Could it be one of these? http://www.amphenolrf.com/products/precision.asp
I used a few of them in a ham Amateur TV transmitter I built years ago. They
sound exactly like what you have.

is the TED connector you were asking about. Not familiar with the one on the
KI-214.

Amphenol and Pasternak websites and didn't see anything that resembled what I've

only for King and is available only thorugh them... I had the same problem 2
years ago... I have a background in industrial electronics and I understand
how to get proprietary parts, but I was not able to end run King on that
one... I bought the connector and shell from Eastern Aviation when I
purchased the KI214 and had my local radio shop hang the connector on the
harness for me and bench test the KX-170B - KI-214 before I twisted my
spine into a pretzel installing it... I darn sure wasn't going to have to
take it back out because it didn't work....

Amphenol and Kings (no relation to Bendix/King) made that connector in the "MB"
series and that it was popular (!?) on "low performance mobile radios", whatever
that means. However, rather than spend a couple of days trying to find dusty
stock on somebody's shelf, I'm just going to bite the bullet and trundle down to
either my local two-way shop OR the avionics shop down in Auburn.

Jim, you've got the right connector series for that little mini-BNC. It's also
an Automatic Connector, Inc "BSM" series, and it seems they've still got
it in production. I'll ask my tech tomorrow morning if he's got any stashed
in his toolbox - I think they might have been used on our internal gas main
inspection robot.

connector, not the proprietary edge connector (that's what I get for not
reading the whole thread)... What I did on that was change out the mini BNC
female on the KI214 for a standard BNC... I absolutely refused to pay King
their highway robbery price for that connector to go on the coax...... It
is a bit of metal work but not at all daunting for the handy ham...

Just as a suggestion take a look at HRS or Hirose connectors. They are
what was on a lot of older handhealds...
Fairly good pricing still compared to the others.

head I was replacing, so it was a no brainer... I could give King/radio
shop $70 for a bastard BNC, or give em the finger... Thanks for the
reminder on the Hirose connectors...
