Guess our authorities knew a thing or two when they allowed us 1W ERP. bet they thought they will never get there,mebbe they were right. Hi. 73s Laurie.. I had this problem when I used just plastic string as an insulator. I solved the problem by using loops of white cable tie as insulators. As you are near the sea, you may have the same trouble as Mike, GW4HXO. His insulators were covered in salt (I tasted one!!). Perhaps some grease on the insulator will help. Mike, G3XDV PS. I did not get on 73k last Friday as my virus got really bad and I have only now got out of bed. Should be active next Friday.
