I have a couple of TrueTime 560 PCI cards for the PC that can generate
IRIG-B time

I have this DATUM clock that can free run or can be programed with an
IRIGB signal. I wonder if anyone has some software to generate the IRIG
formated signal with a PC or even with Micro Processor
A converter to take the output from my Z3801A and send IRIG B
to my clock would be even better.

Larry,
The Oscilloquartz 8788 is available brand new for $340 at 1ea.
It's phase noise spec is superior to the 10811A & it requires only +12Vdc.
You might check them out.

Is the group purchase of the thunderbolt GPSDO still in the works?

Hi Rick,
You are absolutely right - I should've mentioned the specs first.
It is an Oscilloqaurtz 8788 locked to GPS.
Phase noise at 10MHz:
Hz dBc/Hz
1 -100
10 -130
100 -152

As always, "without degrading the phase noise" is only half of the spec.
The other half is "at offsets of X Hz and beyond." What is X? It can make
all the difference.
I'd look at using a PLL to lock a 100 MHz VCXO to your 10 MHz source. If
you are willing to lock one crystal oscillator to anoth
Hi all,
How difficult is it to multiply a frequency standard from 10MHz to 100MHz?
I found the recent discussion about amplifying a 10MHz OCXO output from 5dBm

Hello all:
I considering a do-it-yourself GPSDO, and I started by looking for a
good OCXO. I have been given a quote for a unit with the following
phase-noise numbers:
-120 dBc/Hz at 10 Hz
-145 dBc/Hz at 100 Hz
-155 dBc/Hz at 1 kHz
-160 dBc/Hz at 10 KHz
-160 dBc/Hz at 100 KHz
My question is this

Hello Ulrich and hello Nigel (nice to meet you here as well!),
I would like to help if possible, as I am owner of a FRK-HLN

the FRK (H or L) , but I realized quite soon, that the content of my

Rob, thanks so much for providing this! This has been one of the most
elusive manuals out there, so it's really great to have it available now.
Thanks!

Hi folks,
please allow me to ask the group on behalf of the future member Nigel
