I knew something was up when it took 5 months, then they lost my tube. And nobody knew what was going on...or was answering emails.

I typical receive my audio and everything else on a Tentec rx 350.
But from time to time I also check my audio on my 148.
It shouldnt sound any different if you run 1 watt 100 or 10000 watts...if you linear and can monitor a trapizode.
The scope and REA say one thing. But your ears may say...
I had one back in the 90's.
I remember testing it at the Belmar marina, comparing it with 102" fighting stick, a coil and and a Wilson 5000.
~ Equal to the 102"
Better then the Wilson 5000 or coil.
It smacked a tree and got recycled fairly quicky on my chevy van.
Not worth the $$$.
2 cents..My at least 35 year old dumpster find analog O-scope is easy, quick and intuitive. Displaying analog data with an analog scope is the way the radio gods intended it.
My digital is somewhere on the shelf. But it works.
True "hifi" at AM is 20htz-20k at 80% positive and ~ 80% negative.
In reality 80htz-12k at 130% positive and 90% is good enough.
None of the above requires special software or boards.
I've run Yagi's at 6' off the ground to 120' off the ground. In my stupid uneducated experience....anything above 36' is good enough.
Running a quad at 50' now..seems good. But it also worked just fine a 12'.
