Vintage Quartz Crystal Manufacturing
Can you say "Mr Rogers' Neighborhood?" I knew you could...
He (along with creepy Mr McFeelie) always ran segments on how some item was made. Geared towards pre-schoolers, but always worth watching.
Compare the Science channel's new "How Do They Do It" to the older "How It's Made"
shows.
I bought some old crystals on ebay :
http://www.ebay.co.uk/itm/122225114483
Is anyone familiar with this style ? I don't think the quartz is visible in
the glass section : I imagine that's just an insulator. I think the quartz
is under a brass disc, with a sping to hold the disc down visible through
the glass.
Does anyone know what the reference marked on them "w'less sets No 7"
refers to ?

Might be worth popping over to the GQRP mailing list and asking, there are
a few enthusiasts there but wireless set no. 7 makes it sound like they
were from a military radio.

Hi Adrian (in the UK I think) I think you will find the designation WS.7 is
a UK Military type number. Try and search vintage military radio.
Lovely beasties, I have not seen that configuration and they are probably
quite early in the use of quartz in sets on a manufacturing scale

Hi
Welcome to eBay …..
I don’t believe those are crystals at all. If you take a look at the markings on the parts
they are labeled “80 K cps”. In other words they are 80 KHz not 80M devices. Looking
at the gap, if there is a crystal in there it’s not obvious that it’s big enough for 80 KHz.
My guess is that they are tank tuning caps for an mechanical MOPA style transmitter.
The size and construction are about right for that sort of thing. Swap one in and the
transmit frequency changes. Number 7 for 80 KHz. Number 8 for 85 KHz. Number 7 for
75 KHz. Just a guess …

Not sure where you got the 80 K cps the seller mentions 80M(eter) and
the items are clearly marked 3720 KCS 3760 KCS and 3780 KCS which would
be in the 80 meter band.

Wow, those are really neat. I have several hundred different style holders in my collection, but, I have never seen any like those. Thanks for sharing. Now to find one :). Regards - Mike

Actually, there is a 37 before the last digits, so they are 3720, 3760 and
3780 kHz.

To me, these devices look like they may have a quartz crystal at the bottom, and spring and screw adjuster on the top.

The markings are actually 3720 k/cs, 3760 k/cs and 3780 k/cs. And I think
it's probably for the wireless No 7 shown in http://www.wftw.nl/wsets.html.
But you could be right - they may not be crystals.
As for ebay .. yes, buyer beware. Though in this case I know the seller
personally and while he might be mistaken, he won't be intentionally
misleading.
