Hi Bill,
it is very dependent which is closer to the receiver
here in the Bay Area sometimes you can't hear local AM stations either.

Hi
The Loran-C frequency allocation is standard pretty much over the entire globe.
Switching power supply noise will eventually take out all RF communication …

Hi Alex,
100 Khz is not protected however the interference from SMPS is annoying but
will not bother loran transmissions as it is much stronger than that
interference.

Hi,
Some first tests of the NIST UT1 service recently announced. Forwarded comms
with Judah Levine. I’d be interested to hear the experiences of others .

Try the Time Interval mode of the SR620: maybe that mode can fill up
the 16digit display... the interesting feature of the SR620 is the
25ps single shot resolution not the 16digit display to be filled up.
The SR620 is an 11 digits per second counter (at 25ps resolution) or
12 digits in 10 seconds .
Hi Bill ,
is the Loran frequency 100kHz protected? because there are may switching
mode power supplies which generate lots of Loran replacementsthe same is
with wwvb 's 60kHz

Hi,
I got two of this time and frequency standards but i didn´t find any
information on the net.
Can anybody help?

I believe the inputs far more flexible then the limit suggested. Typically
the low level is the issue. In the spec sheet I see it says .15V.
If you had a 10 db anttenuator that would be a good start.
The good news is it sounds like you have enough signal to drive both things
pretty easily.

How do I know its the 3586. All other systems are working and not failing.
Using the same austron 2100 with another stable reference source has no
problem.
Alex there is only 1 station on the east coast the gri is 89700. But simply
tune the 3586 to 100 Kh
Hello Max:
I use a SMA Coax attenuator to connect my GPSDO/Rb Stand with the EXT Ref
port of other equipment, the GPSDO/Rb often provides +7 ~ +13dBm output level,
I believe it's too high for a EXT ref source, so I often use a 10dB attenuator
to put it there, actually I like use another 10 ~
Dear Group:
I have a SR620 Universal Time Interval Counter, I know it has a 16 digit
LSD, my question is can these all 16 digit displayed in same time?
I have tried feed it with 1Ghz frequency, or just feed 1Mhz frequency by
pressing both the up and down arrow keys together toggles the x
Alex - are you referring to the test of eloran in progress from Wildwood NJ?
That of course is on 100 Khz. There is no Loran in California at this time.
