These seem a good deal but the shipping price to the UK puts me off a bit -
it's 3 x the price of the unit.
I've looked into shipping a number of them to get a better rate and it
seems worthwhile. I'm happy to sell them on to time-nuts at cost (will
include shipping and duty) and ebay the
Does anyone know the procedure for resetting the output level constants in
these generators? The manuals I’ve found are silent on this, but it was
obviously done at the factory… Mine needs levelling.

Bevor I heat up the big soldering iron to remove the OCXO, I wanted to
ask if anybody else experienced this before and if anybody can confirm
that tuning voltage range is indeed 0..6 Volt. If so, replacing the OCXO
should cure the problem.
Hi Mathias
I've not experience your problem
You might look into GPS devices. They aren't quite as cheap as the WWVB
chips, but there are lots of them on the market.
Yes GPS receivers can be very cheap and self contained and much easier yo
use than those WWVB chips. I have two of the chips. I don't think they
work now that WWVB has

Wondering if anyone knows, and maybe it's not possible to start LH with the map
displaying signals. I can enable the map with /gb, from the command line but
can't seem to find a switch to toggle between azimuth, weighted azimuth,
elevation, Signals,Data etc that would normally be available
I ended up with a dead REF1, so I decided to investigate.
The -15V was at -0.6V and the 15V at 3.5V. The power module was hot
to the touch.
Then I found Bob Stewart's post from a few months back, so I decided
to pull the power module and check the capacitors. First, I measured
the resistance
Just on my OP is there a command line to change from dbc to AMU. Everyone in a

Hi
It’s a pretty good bet that what ever is *really* is a generic PNP or NPN
device will drop in. You need a low frequency device like the 3904 series.
It’s going to carry about 40 ma to your antenna. A high(er) current part (Ic
max 100 ma) is
better than a low(er) current (Ic max 20 ma)
If you need time the GPS chips are the way to go.
Heavens for $11 I think you get the complete system with antenna.
The old wwvb chips do still work as well as they ever did. They detect AM
and thats still a part of the format. They are as reliable as they ever
were. (Sort of not if you live on
The difficult thing about that is that making the wifi connection without
any user interface is difficult now that most wifi connections have
security enabled.

Agree with Bob. The fact that the top is blown off sounds like a bit of
lightning.
You can easily adapt a classic npn or pnp in for a temporary test. 3904 or
3906.
I have needed to do this on other things. It confirms quickly thats the
issue and then you just need the new smt to solder in.

Hello Time-Nuts,
I have a RFTG-U REF-0 / REF-1 pair here which seems to have a problem.
The error LED of the REF-1 box stays on forever, and Ulrichs SW reports
an EFC Error. After OCXO warmup, the EFC goes doen to it´s lower rail
(-100 %) and stays there forever.
Indeed the 5 MHz Output
Chris,
did you allready get your photos?
If not, I can open up mine tonight and see if I can make

Hi Everyone,
Thanks for the suggestions this past weekend for helping get my new Thunderbolt
fixed. I got back into town last night
I just installed Windows 10 (yes I know how rash), and now my Thunderbolt is
being detected as a Microsoft Serial Ballpoint Mouse (yes, just like before
inder Windows 7). I had set something up on Windows 7 in the boot.ini to
stop this, but for the life on me I can't remember what it was.
Please

Tahnks to John Lofgren:
Click on start -- In the search box, type in regedit Registry editor
windows opens... Navigate to the location:
HKEY_LOCAL_MACHINE
-- SYSTEM
-- CurrentControlSet
-- Services
-- sermouse
In the right hand, you'll see stuff like:

DisplayName
etc. etc.
You can disable serial mouse detection:

If you are using an old mouse, it might disable it as well and
you will need to use a USB mouse.

Hi
I suspect that postage throughout Europe would be much better after a bulk
transit over the ocean. The units are already (or maybe better put still)
packed in
air shipping boxes with “Korean Air” tags on them. The seller then re-boxes
those
inside another box. I would not have any real fear
The OCXO in these units is the MTI-Milliren model 260. According to its
datasheet, the tuning voltage range is -10Vto +10V.

I've ordered some. Please contact me directly rather than via the list if
you're interested in one or more. The seller will repackaged them to reduce
shipping so they won't be boxed quite as advertised but should be good
enough.

All,
I poked around inside the KS-24361 REF-1 today to see how easy it would be
to replace/upgrade the Oncore GPS. I wasn't too successful, but I decided
to write up my findings anyway. Perhaps the information will be useful to
someone else as a starting point.

Hi
From your description it sounds like you have done a very complete analysis of
the problem. The
only other thing you *could* do is to run the EFC over 0 to 6V with a power
supply and see just
how the OCXO behaves. It would not tell you much more than you know already. It
might blow
