Re: [Elecraft] So today i learned about BNC-BP and red/black terminals
Well...this has been an interesting revelation. I just happened to have two of those adapters, one with a female BNC and the other with a male BNC, laying in my collection of adapters. The one with the male BNC had the red screw cap on the side with the tab and that side was electrically the shield portion of the BNC connector. The other adapter had the red cap on the side that was electrically the center conductor of the BNC connector. Although there were no manufacturing markings anywhere on the adapters, physically the molded portions appeared to be identical, indicating that potentially the same manufacturer made both parts. Electrically, the two parts were correct with only the screw cap colors reversed on one. So, maybe the final assembly person was color blind or 50% right was good enough for their quality control department. 73, Henry - K4TMC On Mon, Aug 29, 2022 at 10:56 PM Marshall Harrison wrote: > No, that is not a convention.

Aha! I now see the tab. Thanks for the feedback. w8lvn On Mon, Aug 29, 2022 at 9:54 PM Marshall Harrison wrote: > No, that is not a convention.

Re: [Elecraft] Problem with KAT500 firmware v. 2.05
Was the issue resolved? Any update on the state of the investigation and whether a firmware defect was confirmed?
