SO I just did another mosfet mod to a friends CB. (by the way , if you are buying the 520's get the VISHAY ones from Digikey. I got a couple from international rectifier and they really sucked) .
So when I test, I test with a 50 ohm dummy load and my Galaxy 717 SWR meterand am seeing a hair over 40w PEP. I confirm this on my Polaris meter then hook it to my firestick, confirm my SWR 1.2 -1 and talk to people clearly 10 miles away. everything is fine an dandy.
I hand the radio off to my buddy and he hooks it to his antenna (wilson 1000 base loaded on the top of his truck. dead center roof) I make a couple small adjustments and get his SWR downl that the needle barely moves on the meter. As close to 1 -1 as I have ever gotten. Flip to WATTS aaaannnnd
6 watts DK and 12 watts swing. HUH? Whaaaa? I go round and round with this trying to figure out what the hell is going on. I am thinking internal short on the antenna (base loaded coil) so I grab another K40 base loaded and lo and behold
5w DK and 10w swing.
Am I just doing something STUPID or am I missing something that any good CB tech should know.
Put the Dummy load on the end of his cable, 40w swing.
I admit I do not know everything, so any hints?
