content: it's not recommended to use metal polish on silver/nickel plated connectors. but i think it is worst to use a abrasive on BADLY corroded bnc's.also don't use metal polish on gold plated connectors.

content: Those don't look silver plated. Corroded silver plating turns a dark (almost black) color.Those look like plain old nickel plated BNC connectors.

content: Flush the polish residue if you haven't already with IPA. Most of them say if suitable for nickle but it will eventually wear the plating if trace amounts are left.

But even when I was in the 25 - 30 WPM range, when I heard someone calling CQ at a painfully slow 5 WPM (sometimes less), I would take a deep breath, turn the speed WAAAYYY down on the keyer, and go back to the guy. We would have a very enjoyable, although slow, conversation.

content: When it's so screwed up it's totally unusable "not recommended" doesn't really apply. You can't really further damage something that's already scrap and I'll hazard a guess this got the instrument in service much faster than tearing it apart, sourcing new BNCs the fit, and installing them.Also, where was this thing stored to corrode it that badly? A cabinet full of acids?

content: Quote from: BrokenYugo on January 03, 2022, 06:17:26 pmthis is why it is on the repair thread. it's normal to get intermittent connection issues with badly corroded bnc. if you LOOKED into the picture the bnc is just tarnished. the gold plating is in good condition. replacing the original amphenol bnc will cost more than the actual oscilloscope. yes. i could replace it with a new bnc. but is maintaining it a better option?i live on a coastal area, the equipment i have is old hp/tektronix. replacing a bnc can break circuit boards of could go out of alignment.

content: Regarding the inner conductor of BNC and comparable connectors, I have used the following tools:- a well worn (pre-dulled) thin dental diamond burr with the right conicity (not in powered tool and with much feeling)- the wire-form blades from an actual contact burnisher- small interdental brushes (especially together with de-oxit or tunerspray)

content: Quote from: m3vuv on December 31, 2021, 07:37:51 pmI agree with some of the other comments above. This was uncalled for. Would you call someone a twat or numpty in real life for asking a question? If so, I think you might be the twat. How about we try to be a little more polite and help others rather than criticise.
