Yep I have a AL-80B and it tunes sort of OK on the WARC bands.
Problem is Ameritron AL-80A and B has one tuned input circuit for both 10M
and 12M
And another single circuit for 15 and 17M
And another for 20/30M
And they are a compromise
So you may have VSWR from exciter to linear input
I Asked Ameritron about this and they confirmed it.
But my ATU in the exciter compensates very well -- so no problem.

I found the AL-80B's exclusive Dynamic ALC - to be a nightmare -- so
modded mine to be an AL-80A

I didn't mean to imply big linears for 30 M as it is limited to max 200
Watts out.
Just mentioning (not too well hi hi) that WARC bands include 30 Meters
But My Ameritron is labeled 20/30 Meters, so perhaps one might use a linear
to get 200 Watts -- I never do, however.

some amps won't tune on the WARC bands ---- I was referring to old amps
like Heathkit, Kenwood and others that do not tune the WARC Bands

A ham here frazzled a Kenwood amp trying to horse it to 12M

Maybe some amps won't tune on the WARC bands, but my Ameritron AL-80A
tunes
up just fine on 18 and 24 MHz.

I can't see how anyone could use an amp on thirty meters, unless they were
running something like an FT-817 as an exciter.

I and many many other Hams would not consider selling a linear to a
non-ham, so -- I so informed him -- he reposted with his callsign --
I'll
bet he gets lots more responses now

And he didn't specify power or bands and as I sed many older linears
don't
cover the WARC bands.

So all that was helpful (agree?)

Your response was not.

" Are you just trying to start an arguement?? I can see nothing in his
original post that would cause me to think he was a CB'er. Just
because
he
didn't post his callsign? Stop playing newsgroup cop and go away. I
don't
care if you go away mad, just go away.
