"Brad" wrote in message ... "robert casey" wrote in message hlink.net... Perhaps they could demonstrate a PL259 connector instead? Extra credit if they can do it without melting the dielectric insulation of the coax. More points if they can get the solder to actually flow onto the connector body where the shield solder holes are located (helps if you use a small file to remove the plating first). And more points if they remember to put the shell on the cable in the correct direction before doing any soldering ;-) Or they could demonstrate extra skills and just use crimp on PL259's like I do. These are much easier and more reliable. They are more expensive but their construction is superior. My original comment was directed at Dee offering points for something called a "PL256". Brad Yup, some days I can't type. The crimp on would also be an option since I did (purposely) phrase it as install it. In either case, the pass/fail criteria would be continuity with no shorts.

"Brad" wrote in message ... "Da udder one ya dont know" wrote in message oups.com... Solderless connectors for RF applications? A quick fix for sure but not a lasting one! The only crimped connector I've ever seen work is the cable TV connectors and the center conductor us used directly. Crimp on RF connectors have been used for decades, BNC, TNC and N connectors, good to 1.5GHz, UHF connectors to 500MHz. Used in most avionic and military applications. (many of the connectors have a mil p/n) The crimp forms a cold weld which is better than solder and more reliable considering that the crimp tools are calibrated. http://www.radiall.com/vdocportal/po...egoryId=382831 Download the BNC catalog, go to Page 12 for a sample of BNC crimp on connectors. The UHF's are similar. Brad. Unfortunately too many of the installations are sub par. When I have purchased antennas that came with crimp on connectors, such as many mobile antennas, I've had to replace the connector in under a year. Dee D. Flint, N8UZE |

One can put up a wide variety of antennas without a tower. True! On the other hand, I've often thought that a person (unless handicapped) should demonstrate putting a simple PL-256 on coax. Oh, is that a new kind of connector? I like using PL-259's on coax myself! :) Ok, I accept the 50 lashes with a wet noodle. Dee D. Flint, N8UZE |

Flint, N8UZE Dee, I have worked in broadcast and manufacturing. 95% of the failed RF connectors I've seen were crimped. I've never had a soldered PL259 come off after I started using the described method. The assemblers at Microdyne were required to put completed crimped cables into a fixture that applied the manufacturer's specified tension on each crimped connector. Most of the SMA we used were still soldered, either on flex or semi-rigid cable. In 30 years I have only seen a few cracked solder joints on semirigid, and that was on N" connectors in Collins 4 GHz Satellite TV receivers. Over half of the units I repaired for United Video Cablevision had bad solder work on the RF input connectors. I was at a hamfest a few years ago and bought a box full of PL259 connectors that were cut off bad cables. I used needle nose to pull the insulation out and held the shell over a propane torch a few seconds and dropped it on the bench to remove the loose stands and old solder. After they had cooled I did the center pins that way. No damage to any of them and all were nicely tinned for re-use. -- Former professional electron wrangler. Michael A. Terrell Central Florida |

I didn't make the cables one at a time. I would make dozens and it went very fast because I did it like a small assembly line. Not only that but people paid about $3 per connector I installed than anyone else in the area wanted. I could make about a dozen cables in an hour, back when I was in the RF business. I didn't make, or use RG58 cables. Only RG-8 or 213. I have to find the right connectors for the teflon coax I have in the shop. I think its two spools of RG-179 and a spool of RG-400 Who says you can't get a shorted cable with crimp connectors? I've seen plenty of shorted cables with crimped connectors. -- Former professional electron wrangler. Michael A. Terrell Central Florida |

Morse gone by the beginning of last year.

I guess it's because I rarely check USENET anymore, I'm mostly OTA in my spare time. (Which, sadly, isn't much.) I do agree that there are a multitude of ways folks can enjoy AR. I also believe that the code "impediment" was removed in 1991 (?) when the No-code Technician class license was created, thus negating the infamous "barrier" argument. Some have said that this is insufficient without HF privies. From a relative newbie's perspective, this is kinda shameless. (I really don't mean to sound inflammatory, but...) I suppose I'm "old school" but I think privileges are just that, privileges and not rights. I consider it a privilege to be able to access part of the HF spectrum where calls like 3D2NA (Fiji Isles) or 3Z1IARU (Sp. IARU commemorative station) literally "emerge from the ethers," work 'em and subsequently receive their QSL card. Is that for everybody, I suppose not. Many of these calls are not so prevalent on phone though. I also believe it was a very good thing that the No-code Tech ticket opened AR to many who weren't quite ready to commit themselves to learning the Morse code. However, to ask that all three license classes be made "No-code" is somewhat akin to being given a nice juicy hamburger and then demanding that it be steak, hence kinda shameless. My original statement stands. There are lots of folks that could be enjoying some serious DX who don't even know how much they'd enjoy it if they would simply focus their energies on rote memorizing 43 sounds rather than complaining about how unfair the code test requirement is. Anyway, I don't believe it was ever really about the code test. Drop Element 1 completely AND do away with the published Q&A pools, THEN brace for some serious bellyaching. I think the FCC will recognize that too many present licensees support the retention of Element 1 to drop it completely. Look for it to remain for the Extra class ticket.
