I work in the Radio Shop for a fairly large city. We deal with everything
from WiFi in police cars to a regional UHF T-Band P-25 trunked system.
Essentially every RF connector we put on (except hardline) is a crimp type
connector. We have the proper cable stripping, and crimp tools for them as
well. The crimps are FAR faster to install, and when done properly with
the right tools, every bit as reliable (or more so) than a soldered
connector.
Personally I really dislike the "old school" Type-N connectors. Had way
too many fail. The usual failure mode is that the cable is not
mechanically attached to the connector well enough, and with some handling,
the strands of the shield start breaking until the cable pulls out of the
connector. For home use (where I don't own many hundreds of dollars of the
proper crimp tools), I much prefer the newer Type-N connectors that are put
together more like a PL-259. Yes, I know that they are not as perfect as
the "old school" Type-N, they don't come apart.

Subject: [amsat-bb] Best Connectors?
Hi All,
I till last night thought I found the "Holy Grail" of a connector and
connector source.
But maybe was blown down by a "Professional" That does all this "Radio
Stuff" for a living.
I always LOVED the old "N" connectors. With the big rubber clamping
thing inside for the shield. And always wished that method was available
on other connectors, even the old PL-259.
A few weeks ago I found them, Like this,
http://dxavenue.com/131-465-thickbox/pl-259-clamp-connector-uhf-male.jpg
and I found a source, that is not only CHEAP, but in any combination
you could even dream of. So No losses from adapters. Like from LMR-400
to Male BNC, or even LMR-400 to female SMA.
I bought three connectors.
(2) LMR-400 to Male BNC
(1) Male BNC to Female SMA
Total cost only 9 bucks and 3 days shipping time!
OK, I was sooo happy I had to bring them to the club meeting last night
to let everyone else know of this find. And a guy that works for a land
mobile company. They do all the radio work around here for the police,
FD etc. And he said he wished he knew I wanted them. They got a box of a
hundred in the storage room. A lot of equipment comes with the
connectors like these but they refuse to use them. He said they are not
reliable and the ground connection fails.
I never heard of this before. What is everyones thoughts here?

I have switched to crimp connectors and I do not think that the shield
connections, on N connectors, is any less secure than the "old school type".
?In every case, the sheild is compressed against the connector body. ?Ithink
the crimp connector makes a better shield connection. ?This topic came up on
another group and someone on that group said the military only uses crimp
connectors now. ?I could not verify his statement but it seems to me that it
is much easier to make a reliable connection with crimp than with solder.
Just my 2 cents worth.

I too work in the profession and try to stay away from the old style. Not
only will the shield eventually release but the center pin will at times
recess. I use crimp whenever possible.

Greetings everyone,
We, students of IIT Bombay, are glad to inform you that our project,
Pratham, is ready and expected to launch with PSLV-C35 in the last week of
September. We would be really happy if you all joined us in receiving our
satellite's beacon, details given below:
Beacon:
Mode: CW
wpm: 35 words
Frequency: 145.980 MHz
Downlink:
Mode: FSK
Baudrate: 1200 bps
Frequency: 437.455 MHz
(To be switched on over France and India only)
We will update the information as soon as TLE's will be available.
Kind Regards.

9 days from now, Wyatt, AC0RA, and myself will be getting on the boat in
Ventura, CA with our destination set on CM93. We've been training all
summer, finalizing equipment, setting skeds, and generally getting all the
loose ends tied up, and we look to be ready to go.
We have posted our Final pass schedule on the K6R QRZ page at
https://www.qrz.com/lookup/K6R - so feel free to find a pass that is to
your liking. We have tried hard to include everyone in our distance range
on at least 1 or 2 passes. Of course all passes are dependent on weather,
schedule, and other factors - and there's a very good chance we'll show up
on passes that AREN'T on our list as well.. find a window, and see if we're
around.
We're also happy to announce that Jimmy, KK6FAH will be serving as our
pilot relay station for the expedition. He's a fellow AMSAT operator, and
has a QTH right in Ventura, and we should be in local repeater range of
each other while we're on the Island. We have agreed to meet up each
evening and report our logs to him, and he will then pass our report on to
the BB. Please do not email him with questions about busted calls or the
like, he's simply going to be passing on our reports. He's also been
awesome in helping us with some local arrangements, and we appreciate his
assistance with this project greatly.
I'd also like to make a brief request for folks to use some good
situational awareness while we're out there. We know this is a rare grid
and there's tons of interest, but remember that the birds and pass time are
a scarce resource. We're hoping with lots of scheduled passes there should
be more than enough air time to get everyone worked that wants it, but use
some common sense. If you have linear capability, find us on one of those
birds, and leave SO-50 for the FM only operators. If you're on the West
coast and can work us on a higher pass where the east coast doesn't have a
footprint, consider delaying to give them a chance. If you can handle
taking a night off from using SO-50 as your ragchew repeater in the sky,
that'd be great too... and please try to keep the dupes to a minimum - you
never know when someone is just sliding into the footprint and only has 30
seconds to make that precious QSO. Thanks in advance.
Finally, we're planning to do a very informal round table on 20 meters
Saturday night at 8:00 PDT. Clayton, W5PFG has agreed to find us a
frequency (probably the upper portion of 20m) and send out a tweet on where
we will be. We'd love to have you stop by on HF and chat about Satellite
stuff, the expedition, or "Am I in the log?" that night.
It's expedition go time. Hope to catch everyone from CM93!
73!
Dave, KG5CCI

I also now use mostly crimp connections. The tools aren't that expensive, I
spent under $100. Before I retired one of the last projects I did was do the
engineering on the 10 year tech refresh for the 20 FAA ARTCC's GPS time
source. I had to spec a 200 + foot cable run from the antenna on the roof to
the actual time source unit. I worked with crimp connectors exclusively.
After I did some crimps, I will never go back to solder. I do find it easier
to solder the center pin though.
On the old N type, I always had issues after awhile with the shield coming
out on the cable run from the rotor loop to the antenna. If you must solder,
use the newer type that go together like a PL-259 like Jim suggested. They
will last much longer ...

I too work in the profession and try to stay away from the old style. Not
only will the shield eventually release but the center pin will at times
recess. I use crimp whenever possible.

I'm finding this an interesting thread. I've always been partial
to clamp N connectors my self. When I've needed to replace cable,
I just un-clamp de-solder the center pin and re-use the connector.
I will say over the years, I have had to numerous times re-do the
clamp-ons around the rotor and antennas as they do become loose
and lose shield ground as others here have noted.
I may look into crimp.

I agree 100%, I'm glad I asked this question.
I myself never in my mind thought a crimp as being a superior connection.
Solder is best, and that seems to all agree.
But like an "N", is there such a thing as an all soldering format?
Or "BNC" or any common connector.
