I had similar difficulties with my SR620. I rewired the cables to the power
switch so that the out position now switches the power on and the in
position switches the power off. This has worked for me in the last 4 years.

Dear all,
Since nobody seems to have pointed it out, a NIST time and frequency lab
employee in Boulder, Dave Wineland has been awarded the Nobel price in
physics, together with Serge Haroche.

Of course, Nobel Prize winners get about $1.2 million and the winners of the
physics Nobel will split that. At a news conference today in Boulder,
Colorado, Dave Wineland said he has no idea what he will do with the money.

Dear Magnus,
Good morning.
We popped a champagne bottle (well, a toast with a cup of coffee and cookies
actually) at CENAM as we heard about the news! Congratullations to NIST, Dave,
Serge and all the Time and Frequency community. It is really an awe inspiring
event.
Who's next?
Regards!
Hello Folks,
I have for sale 2 Vectron Model 204-888 OCXO's
5 MHzSquare can and uses an SMA output connector
These 2 were used as the reference oscillators in a 14 Ghz satellite
uplink.
Best offer plus shipping.
I will offer other oscillators both OCXO and rubidium I have if there are
Any BVA left?

Please take care that the S14WI is smart: if it doesn't sense a DC
current on the antenna port then it reports that to the user ports and I
think it can even power off the internal amplifier, this can account for
the observed loss instead of the gain.

Magnus what would the possibility be of measuring an 8 way satellite
splitter? The $7 wonders with dc pass through. That looks like a very nice
network analyzer you have.

To test this kind of items, you have to play with DC-blocks and bias-tees.
Rather tedious but necessary. I know as at times I have to test
questionable GPS antennae that return after lightning strikes.

Azelio,
Not at all the satellite splitters can be smart or passive. I use a passive
so it has 1 dc path. But all of the other ports have dc blocks built in.
The smarter units will direct the highest DC to the antenna. Its really
diodes and I stay clear of those. To smart for there own good.

The HP / Symmetricom 58536A has a gain spec of 0 +-3 db so something is
clearly wrong. Did you power it through a spare port? Also, the
isolation spec is 26 db @ L1. The 50 db spec is for L1 +- 40 MHz.
I looked inside mine and found that there's an input filter(-1db), 21 db
amp, 4 way
A stupid question, but why would you bother testing an antenna? I would think
with antennas so cheap and labor expensive it would be far more efficient to
make a single site visit and simply replace the suspect antennas with new ones.

Dear Peter,
If your budget is $10 for an R.F. Project, spend $1 on the radio and $9 on the
antenna.
At least me, if I troubleshoot by replacing parts, I would be missing the fun,
experience and learning out of it.
Just my 0.02 cents

Agreed. I didn't have the spare energy to follow up on that.

Yes. Port 4. Will look at that again.
Also, the isolation
