Hello everyone, Thank you for the quick replies. Sorry, was driving home and couldn’t reply earlier.
About the radials, they are 14ft each copper wires. Thanks for the suggestion about extending them. Will try to build more in the coming weekend’s. On the radio, it’s a Yaesu ft710. I am using the dnr but last weekend was worse. I just went back and took down the antenna to figure out what’s going on. On the power, I need to look into it this weekend. I am using a surge protector connected to powerwerx supply. Will try to connect directly and see if that’s the culprit. About the inverted antenna, I need to explore this option. Should be a good learning experiment. Venkata Appala > On Sep 27, 2023, at 6:06 PM, Rick Hiller <rickhille...@gmail.com> wrote: > > Venkat, > What is ur radio? > Rick.
