Thanks

That is a real old web site - saw it many times before.

The problem is - not many safety razor blades anymore - other then
cardboard cutters or utility knife blades.

With the commercial broadcast bands going digital - it is hard to find a
good signal anymore.. Even KDKA is hard to hear at night with the
digital signal of another station in about the same exact place.

Hi,

You are absolutely correct. The way things are changing, I wonder if
future generations will appreciate old tech!

Thanks.

Nandu.

I found this

http://www.midnightscience.com/

So I guess there is still interest.

I am disappointed how there are so few good radio stations
but am very glad there is still NPR.

The real problem is the blades needed to be the Blue Blades. The other ones
did not work well if at all. The blue was not paint, but some form of
coating on the blades that kept them from rusting. I am not sure if it is
similar to the blueing on guns or not.

NPR is pretty interesting, but a mite too liberal for my standards,
what I crave is some good old "Wolfman Jack" or even back a bit
more, "Innersanctem" {sp?} and the squeaking door! XERF DelRio?

Still plenty of stations that rebroadcast the old programs,
but there is still nothing like live radio.

As to NPR and liberalism...they have /many/ good programs that have
nothing to do politics of any sort.

I love this one

The sad part about the AM band is that at night when you can move out of
the local, so much of it is syndicated, and usually the same show or two.
The local stations love it, filler for a time when audience is down, but
no thrill when tuning the band. There was a local station carrying "Coast
to COast" and every time it looked like the station was going to fail,
everyone would say "but what about Coast to Coast?" as if they couldn't
get the program so easily up and down the dial. And when that station did
finally die, another station grabbed it right away. Sad, that station
used to have local programming overnight.

For about a decade, I'd listen to WBZ out of Baston overnight if the local
overnight programming wasn't interesting that night, and the overnight
syndicated programming wasn't interesting. WBZ has a good reach
overnight, and except for the fading, might as well be local then. And
they know it, so they keep local programming (though often the guests and
calls are not just about Boston) and basically invite callers from all
over.

Reception got sporadic when a local station started up at 1040, just above
WBZ.

And I'm finding I'm not listening to much radio late at night.

The real problem is the razor blade had to be a "Blue Blade". I think they
were only made by Gillette. This was not a paint, but some form of coating
on the blade. Not sure if it was similar to the blueing on guns or not.

I'm retired now, but when I was working I'd spend many hours a day
driving and radio was very important to me. When radio pretty much died
I stocked up on CD's but that was hardly the same...it got boring pretty
fast.

Now, I find myself listening to a few hours of NPR on weekends
and that's about it.

BTW: I am also a ham radio operator, but am no longer active.
I actually prefer Usenet.

When my dad and I built the never-to-work crystal set, the plans said
not to use a blue-blade. OTOH, we did try it after the regular razor did
not work.

Gun blueing is available at sporting goods and gun stores. Try it and
see if it works. Then tell us all.

To get my real email address, replace wrongname with dadoheadman.
Then replace nospam with fastmail. Lastly, replace com with us.

There are atleast two kinds. One is the cold blueing that is just brushed
on and wiped off. Not too much trouble, but the process I was thinking of
is the hot blueing that is lots of trouble. Both are not worth my time or
money to try just for a one time deal. Also I do not have any high
impedance ear phones..hihi.

Blue on razor blades is selenium, which is how it
works as diode. Poisonous stuff, have fun, but be
careful.
