The mfj balun is for balanced to unbalanced with a 4 to 1 impedance transformation.. Sorry got distracted with work ! This suits a balanced feed line, but the problem is it should be outside the shack with a clear run to the ant,( it's hard to run balanced line through windows or walls ,you...

And your going to need a good ground system and balun or choke to try and keep the RF out of the shack.

Home made or purchased? Fatter the radiator the wider the bandwidth. I.E 1 inch tube instead of wire should do the trick. Or second suggestion, if you have to use wire ,is to extend the radiator to a 5/8 center fed and feed with a stub (gainmaster style) You can get the swr Down to under 1.2 to...

Problem will almost certainly be CMC.( coax is radiating). Choke and grounds as sp5it said should fix it.

Actually the sark is pretty good .Especially after you have done the multipoint calibration procedure as well as checked the frequency ! Of course it aint going to compare to the Bird.

Could be as simple as a bad patch cable, or CMC on the line causing the swr to change with the additional length of the patch cable. ( so you better check that ground). What does the complex impedance look like? "J" value is pretty high I'm guessing. I agree with Mike. Trust the two analyzers!.

All the filters and ferrite in the world wont fix it if there is RF inside the CAB.

The words honest and amp builder just dont go together in cb vernacular . I also believe correct use of a fist mic is to "close talk it" holding it sideways talking across the element not into it. And I tend to do the same with my D104 and other desk mics.Sit them on my desk turned side on...

Id leave it at that. Resonance will go up a bit when you raise it from 10ft. Or as the guys say ,stand it straight up with the reflector a foot or two off the ground ( dont sit the reflector on the ground)to adjust. I sit mine on a plastic milk crate.

I though it was ,eats roots shoots and leaves,Wait that might be the wombat.

Must be another "merican" thing

Checked the prop forecasts . Christmas Is to east coast Aus 12 utc is best, but any daylight hours could be possible on 20m. The States looks unlikely unless conditions improve . ( but hey , Iv'e been working US long path for the last Hour and the charts say not possible)

well done. You still on 20m?

Me to:D

Ok. then I concur. Filter caps most likely.

More information please.Is the hum on the signal or are you hearing it.?

Or a pole off the veranda if you cant get to the peak.( or fishing line and a slingshot):D

Anyway congrats I see vk9vkl is reserved , must be waiting for you .The whole process is much faster in a Mainland Capitol city, mine only took about a week to process . Now if your gear would hurry up and arrive?

Hey ? You lost me. They must do things differently on the Islands.I thought the WIA was in charge of testing and call sign allocation for amateur licencing ?
