Hmmm. I am a newbie, maybe other people in your audience are as well; in my humble opinion it would be better if you could show us how much difference that actually makes. This is all taking place in a hobbyist environment, not a lab after all. Please excuse my ignorance :)

Good comment and worthy of being pinned. I'm not willing to do any sort of testing where I would risk damaging good parts but recently a person was asking on EEVBLOG about a damaged section of semi-ridged coax. They had bent it and formed a crack. Many people were posting about how to repair it. My suggestion, replace the cable. In that case, because the only thing I was going to damage was some coax, I took the time to show the effects of attempting various repairs. Have a look. www.eevblog.com/forum/rf-microwave/is-is-possible-to-repair-a-hairline-crack-in-semi-rigid-coax/

In my last workplace, I didn't want to repair an instrument SMA connector like this, because I knew it was a nasty solution. They didn't accept it. Many experts don't understand/take that RF is a "different field". Nice demonstration!

Wait, you're saying you work for a company who actually wants you to do even more damage to their equipment? Damaged connectors are the gift that keep on giving. The STDs of the RF world.

LOL, nice to see you posting!

ROFL!!! I said as much in the comments of that video. NEVER try to repair a RF connector. The chance of damaging any connector that ever gets screwed onto it isn't worth the chance and now you have a connector with unknown performance standards.

I mean when you're starting with a garbage quality chinese sma connector to begin with, does it really make much of a difference if it got run over by a truck and then straightened out afterwards? That's pretty much how they are from new too

@@gorak9000 Yes, it still makes a difference. Even cheap import connectors are at least round when new. Trying to straighten it out by wobbling a drill blank in it will leave a slightly out of round which will over time wear out any connector mated to it. You will also never be able to correctly torque the connector due to the increased rotational resistance of the out of round connector.

@@mikesradiorepair It's not only the roundness but the pin and dielectric depths allow the pin to be exposed. Jamming metal into the connector can damage the flat mating surfaces. The idea of "repairing" RF connectors is just a bad idea all around.

Good job, Joe 😅

2 things. One - I've repaired RF connectors in the field so the equipment could be used. This was before the ubiquitous device most now have in their pocket or bra. On the bench is a whole nother story. B - There is a group on groups io where somebody stated that IMSAI and joe are the same person with two channels. I kid you not. Even posted a link to videos....

I wouldn't call it a repair. Worse you ruin more expensive equipment, cables, cause even more down time, second service call to actually fix the problem.... I don't see the upside. I had seen someone post that a few years ago as well that we were the same person. No idea where that came from.

You're damn right! RF is completely different ballgame. Those connectors might cost tens if not HUNDREDS of euros per piece for that matter if they're lab grade... so NEVER repair RF-connectors. It's now worth the possibility to damage other connectors as well.

Worse, you connect your $200,000 instrument to this "repaired" connector. Or your $3000 cable. Even worse, you do it over and over... Then there is all that data you collected with it. Such a bad idea. I would have liked to have seen them run the file over it like they mentioned. lol

You all got it wrong guys, never repair the connector this way, damage the cable accordingly so it fits!

I don't follow their channel but I have watched a few of their videos. I skimmed through the titles after watching this one and saw he has a 24GHz Keysight portable VNA now. Odd to even think of someone pulling dents on one side and playing at 24GHz on the other. Doesn't appear they have done anything with it yet but maybe in the future. Hopefully, he doesn't go jamming drill bits into it. lol.

@@RobB_VK6ES I guess if Keysight wants to be represented by someone "pulling dents" from their RF connectors and calling that a repair, sure, good PR. Similar to his use of a break over torque wrench. Surprised that working for HP, some of the basics wouldn't have rubbed off on him. Then again, it's not like all jobs at HP were technical.
