Dennis, I listened to you several evenings on 160, and given the number of stations calling compared to those you could hear most evenings, I thought you might be suffering from a high noise level on receive locally. Your ability to hear better on December 11 was quite noticeable on my end t

If you plan on doing a lot of the "F" connectors get a proper torque wrench along with the prep tools. PPC connectors, rubber boots for the female side and silicone grease are all good. Search for "F connector torque wrench" will get you some good click types and you don't have to spend a bunch

I acquired some Commsphere Flooded F-11 type coax. I installed compression Type UHF connectors on the coax. I solder the copperclad center conductor to the center pin. The shield braid is connected via compression. The UHF connectors are working but I am concerned about the reliability because th
