In today's world there *is no* market for a tubed AM radio, and a
kit would sell in such tiny numbers, that I was led to think there
is no market, and I would never profit.

I agree with you the market is small, and not profitable. But people
do things for reasons beyond just monetary profit.

Whether anyone else would make a profit is a moot point. They
wouldn't need my design though. And if they did use my design,
they'd still have to work hard at making a prototype free of bugs on
their own.

O.k. Thanks for clarifying.

Have you ever run a business?

laugh/

I am very aware of business, thank you, having co-founded several
startup companies and non-profit ventures the last few years, plus
three sole proprieterships, one of which is still active in the ebook
publishing industry.

Try running a business which pays the bills and puts food on the table,
and which makes you attractive to women, (or a man,whatever is your bent)

Try doing it without capital.

This makes you think twice about time wasting.



I already have described my radio design in full in numerous
postings.

O.k., I'll dig through Google and see what you've said on your tuner.
Love to hear it. Have you made any recordings of received stations?

Nope. I don't believe recording and replaying it
would convey the sound properly.

AM is not regarded as hi-fi by all my friends, its just a tolerable
midi fi medium, great for replays of the Goon show, and forms of music
which don't need a hi-fi medium, like most pop and folk music.



The living better get busy if they want to build a decent AM tuner,
and stop dithering about, if they want one by then end of next
month!

Well, maybe I seem impatient, but... smile/

You seem to have all the time to discuss it all, and make nothing,
like the original armchair solderer, and that's hardly impatient....



And about the so-called "kit", I myself know that it is not a money
maker -- I'm sure you will agree with that.

Well then just design and build your own.

I just might, or as part of a team of like-minded individuals.

When you have tested your first prototype, we might compare notes,
but why before? You could proove you mean to contribute to the
exercize by doing a lot on your own.

snip,

switching 120 sets of LCs to allow only 2 RF amp tubes to be used

presents huge wiring problems, and is, unless *you* prove otherwise,
a complete waste of time.

Agreed about the huge wiring problems, and agreed about having to
prove it, or someone having to prove it. One reason for mentioning it
as I have is to engage the collective creativity of the many people
here in the newsgroups -- to think positive, and to think of a clever
way to make it work. Or, it may catalyze some other idea leading to
some improvement somewhere.

There is a point where *you* have to un-tether yourself from the crowd
and do your own experiments, and make conclusions of your own.
In the absense of anyone else volunteering to do the donkey work
of R&Ding a test circuit, there is only yourself who is left to
realize this dreamy obsession of yours.

Good luck,

Patrick Turner.
