This post has more to do with a firm selling radio stuff than the stuff
itself, and their apparent want not to do business even with people who s
end
on-topic and polite emails at infrequent intervals. That's strange, so I
want
help with that from someone who HAS done business with them, or knows
something about why they refuse to answer a normal sales inquiry.

...

Just checked their web site. Their contact info lists "help@..."
instead of "sales@..." as the email address. Have you tried that?

My impression is that it's a pretty small operation. It might
literally have a staff of one. Who knows what might have happened--
vacation, illness, ...

I'd be a bit careful about ordering anything from a company that lists
so few specs on their equipment. I checked the "receiver preamps"
page and found no mention of some pretty important stuff like third
order intercept, noise figure, and some details of the filter
performance for the "single band" preamps.

Cheers,
Tom

Thankyou. I think I tried both addresses.. First thing after one failed would
be to try the other..

You might be right, could be small enough that
something went wrong and stopped business for a while. I was assuming that
the amount of fabrication needed to make that transformer implied a small
group of people but that IS just my assumption, as one person can 'farm out'
that work with a good design. I take your point about the lack of data, but
as I'm after a passive device recommended by someone who knows a lot more
than I do (I cited one of his messages in my other post just now, it's old
but that shouldn't invalidate it, SW listening is an old exercise, surely
close to 100 years by now), and as that 180A transformer is clearly good
value and low(ish) cost, I think it's a good starting base, though if I can
find John Doty's plans that is also a good start.
