Subject: [time-nuts] Service manual for HP 106B Quartz Oscill
Does anyone know where I might get hold of one of these manuals? (I've
looked in the usual places) I have one of these devices and it needs a bit
of work.
Regards,
Jim

Just to be clear, the modules themselves aren't reconfigurable, but the
mainframe is.
That said, the 1 MHz, 5 MHz and 10 MH

There was never any documentation of the NGOComm
program, because of the proverbial "lack of resources".
The author of the program trained a few people,
and they trained others. I used to know how to
use it, but it has been 10 years since I used
it.

Hi Brooke,
Sorry, my mistake. Try Blue, then "Clear". That should clear your current

My unit's Lamp Voltage does swing up and down until it locks.
It just takes longer than the 3.5 - 4 minutes the manual says.
I checked the Lamp Voltage when Locked and it is 9.4 vdc.

I also have one of those HP oscillators and would be interested in any
documentation concerning NGOComm.

There are two units now listed on the "evil empire", but it is not clear what is

If you want a 'vintage' solution, the HP 5087A can be configured to take a
single 5 or 10 MHz and divide/multiply it to 10 MHz, 5 MHz, 1 MHz and even
0.1 MHz then feed that to various output amplifiers of 10, 5, 1 or 0.1 for

Hi people
I too needed a 1MHz reference to drive my HP5245L counter.
I simply fed the t.bolt's 10 MHz output into a single transistor amp to obtain
5V p.p and divided down using a TTL 7490 chip.
This I followed with a six stage Chebichev 1Mhz low pass filter to "knock-off"
