Re: cannot trust any version or any mod.

Curt Indeed agreed. My V4 is only marginally out of spec on 20m using CW tests. The V5 seemed OK on all bands on CW but at the moment is picking up a? lot more broadcast signals off the same antenna. Very strange. Almost like it's more sensitive than the V4. I put a nooelec filter in line with the antenna and that helped.
Anybody else finding the V5 more sensitive ?
Will finish all tests this weekend and share.
Thanks Laurence KB1HKO

I anticipate that a reliable cure for spurious will emerge soon for v3 and v4, and may apply for v5. Its understood that most of us don't possess a spectrum analyzer. My local club is building 23 ubitx v4 units, and we are correcting spurious. I just got hack in town so I need to find the latest info. I hope you and others hold onto the ubitx to continue with the cool rig. My untreated rig is compliant before mods on several bands. My data is posted here, a summary table.
