Re: [Flexradio] GPS antenna for the 6700

[Greg Jurrens]

Fransisco:

The GPSDO option comes with an external antenna.  It does work reasonably
well if you have a clear view of the sky.  Please follow the instructions
in the hardware manual for proper placement.  If you decide you need a
better antenna, I've had good luck with several Marine GPS antennas.  They
can be purchased online.

Good luck!

Grab it, someone.  This is the antenna I use and it works very, very well.

So... Yes.  Excellent.   Next question.  Is it going to be at all possible for

Re: [Flexradio] Gps

[Jerry Flanders]

Photos of the 6000 backside show an RCA jack labelled "ALC".

Is this a conventional hardware ALC line that allows an external amp 
to cut the 6000's drive power back if the amp detects an overdrive situation?


What is the polarity of the ALC voltage required (I think 
negative-going to cut back is conventional)?


What range of ALC voltage is it designed for (I think most rigs 
operate in the range of 0 to aprx -10)?



Thanks

Jerry W4UK

Very long baseline interferometry, or another way of looking at it, an
antenna the size of the world. Beam steering takes on a WHOLE new meaning
then, when your two (hundred) antennas can be 15,000 km apart.

The key is that the hardware is there to support the software when you get
around to it. Hyu iz schmatt guyz. I was counting on that.

You may use an external GPSDO for the "#1" capability I listed.  You may
not use one for the "#2" capability for several reasons.  Does this help?

Re: [Flexradio] Gps

[Jerry Flanders]

Many of us already have GPSDO capability - can we 
use our external GPSDO 10 MHz source with the 
6000  like we presently do with the 5000 and 1500?


Does the internal one provide any additional 
functions that our external one does not?

SMOP!

(Small matter of programming.)

They have to have a channel from the housekeeping processor to configure
and initialize the GPS receiver so you know that channel exists. OTOH, they
might not use the 1PPS. But if they are at all like me, they would have
routed it to the housekeeping processor somehow just-in-case. So far, they
