Hi Phil,toggle quoted messageShow quoted text
I tried to go down this route, having read several posts in the past to say that the E (400-1000MHz) slugs, particularly the higher power ones, were almost flat up to 1296MHz.
I bought a new 500E slug from the US and found it read a long way out from what I expected. So I didn't know whether I had a dud slug or in fact the folk lore was unreliable.
I took the slug to a local who has a collection of Bird 43s and slugs and a QRO 70cm system. I found that my 500E read correctly at 432MHz. It seems that the recent/cheaper slugs are made in China and the E range ones do not stretch to 1296MHz. These slugs are recognisable by there black finish. The earlier US made (white face) "E" slugs do seem to reach 1926MHz. I have yet to get hold of a white one!
