A caveat
A caveat regarding the use of simple wall wart 12v PS for supplying a OCXO.
I am using a Morion OCXO as 10-MHz reference for my K3EXREF and for
my synthesized A32 PLL in my DEMI 1296 transverter. I got reports of
120-Hz sidebands on my signal (-10dBc) turned out to be due to
excessive AC

Wall warts, especially those with switching power supplies, are ALWAYS a
BAD thing, thanks to the RFI they generate.
A GOOD thing -- a LINEAR supply, wall wart or
Max,
I bought one of the BG7TBL GPSDO from the same seller on eBay. I actually was
just looking for a 10 MHz distribution amplifier and found that he was selling
the GPSDO along with matching Distribution amp for a very good price. There
were options of a square wave output version or a sine
A follow up to my write up... I should have included more details from
personal emails I received from Dave, G3TJP. Bob W7AVK also mentioned the
BG7TBL GPS Disciplined Clock and I totally got my wires crossed and didn't
mention G3TJP in my write-up. Sigh Apologies to Mr. Lankshear... Dave
After posting my message about using an external frequency reference for a
K3 and a QS1R, I got some really nice input and feedback from W7AVK, K3KO,
N4ZR and NK4I. A big thanks to these gents for sending me input and
experience with different solutions.
All the input has been very useful this
I'm looking for a Trimble ThunderBolt Rev E primarily for an external
reference to be used on the NC7J CW Skimmer Server (which I sysop) for
our QS1R SDR. telnet:dxc.nc7j.com
Poking around and doing some research, it's clear I missed the opportunity
a number of years ago to get one for less
Pete, Brian and Bob, thanks for the nice feedback. I looked the RB
solution, but I had not found the Chinese all in one GPSDO. And Pete I'm
glad you jumped in, thought I read that the QS1R would lock on a frequency
from 10-125. I'll ping you separate off line... I had some other projects
I mind
