You had to clean them now and then to get a good contact. The modern ones are plated (you can even get gold plated ones) which should avoid that problem.Anonymoushttps://www.blogger.com/profile/11984840704237681015noreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-89298624724009783982009-07-25T01:34:38.877+01:002009-07-25T01:34:38.877+01:00Julian,

Only problem I remember having with them, is that they could lose their tension and get loose quite easily. They also seemed to build up a coat of oxidization or "tarnish" quite easily, too. But on the good side, they are inexpensive, easy to work with and are pretty easy to find.Larry W2LJhttps://www.blogger.com/profile/11511736425569962662noreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-30710469100382872482009-07-24T11:57:10.703+01:002009-07-24T11:57:10.703+01:00That's a fair point, but perhaps I didn't ...That's a fair point, but perhaps I didn't make it clear enough that I was thinking mainly of simple, usually homebrew QRP equipment. Such gear typically doesn't have anything other than connectors for power, antenna, key and headphones.<br /><br />The standard barrel connectors are normally used for power, while jack sockets are generally used for key, mic and headphones. There is usually only one coaxial socket required, so there is little scope for confusion, especially where the constructor will also be the user. If space is at a premium - such as a transceiver built into an Altoids tin - then phono connectors have the additional benefit of small size.Anonymoushttps://www.blogger.com/profile/11984840704237681015noreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-46286872499421146262009-07-24T11:42:34.166+01:002009-07-24T11:42:34.166+01:00I personally think the phono connector shouldn'...I personally think the phono connector shouldn't be used to carry RF, not because of the losses (or purist views) but because they are mainly used as "accessory" connectors for things like PTT-switching and audio signals.<br /><br />Would you use a 3-pin mains plug instead of an XLR connector ?! It's far safer to use the right type of connector for a specific job - and it makes interfacing much easier, eg: "now, is that phono carrying my RX audio, 12v DC or is the lead from the ATU?"M0PZThttps://www.blogger.com/profile/08761389989891374881noreply@blogger.com
