Re: Comet gp-6 repair
开云体育I have never repaired anything in over 40 yrs that got hit by or a nearby Lighting strike. That ever worked as good as new.

I think it was a Comet. May have been a dual or tri band. We ended up just replacing the antenna. Couldn't determine what value the burnt cap was nor if the others were still good. |

value of Dstar 1.2ghz voice and data radio.
A club that I help is parting from it's 1.2ghz setup for the lack of use and other technical reason.
The radio's are in very good shape. They are keeping the controler as the VHF repeater is still booming.听 Anyone have a idea of the value of those 2 radio?听 Pierre VE2PF听 |

Re: D Connectors
The panel space I have available is very small, so I need to fit 5 of them along with the other connectors. I found some really nice 9-pin connectors from Fischer that are the right look and feel, but the contacts are 24 AWG. Mathematically, the smaller contacts at common spacing in the connector makes a better match to the 90 ohm impedance of the interface than using ordinary 22 AWG contacts.

I want to worry about the high-tech and fun part of this project, but I get stuck on the connectors. That should be the easy part. Bill Ripley, KY5Q ARRL INSTRUCTOR, STEM MENTOR, CW NUT, DXER IN TRAINING Mobile: (505) 980-8353 | Skype: wcripley Email: KY5Q@... -----Original Message-----

Re: D Connectors
开云体育Great info.听 I have gotten into knock-down / drag-out fights with people on this subject.听 Its kind of like 鈥淚f it is on the internet, it has to be true.鈥澨� 听 In answer to Gary鈥檚 question, I think ITT also developed the original Coaxial inserts for the connectors.听 In modern times, there are now HD versions, using the same legacy shell sizes, and even some new miniature shells with even tinier contacts. 听 I happen to be pulling my hair out with connectors for the last few days trying to find a circular MIL connector that is 鈥渕an enough鈥� to pass USB 3.0 and has 22 AWG or larger contacts (as specified by the government).听 I don鈥檛 think it can be done.听 Smallest good connector (that actually works) that I have seen has 23/24 AWG contacts.听 But if its in the spec, it has to be valid.听 Right.听 听 Rip 听 Bill Ripley,

Re: D Connectors
John, VE3AMZ Thanks for the "true" story on D-Sub connector nomenclature.听 I was one of those who incorrectly called it a "DB9".听 I stand corrected.听听 Was it Hewlett-Packard who came up with the D-Sub types that had coax connector version(s)?听 A lot of their 1960's and 70's test equipment had several D-Sub versions with anywhere from 1 to 5 coax connectors. 73,听 Gary听 W3DTN

Re: Anyone here familiar with a Zetron model 42 controller?
Thanks to a kind benefactor (not the OP), there are now manuals for the Zetron Models 42, 49, and 452/459 products on the Zetron page of Repeater-Builder.com.
At least one of these has cable wiring for 9 and 25 pin local computer serial interfacing. |
