For general GPS tinkering I've had good results with this unit, and the price has been very good on Amazon, but it appears to be sold out:  PCTEL / Maxrad - GPS-TMG-50N

Tim, will using an external 10mhz reference work with 2 meters on the 6700?  I am a little off frequency but I thought I read that the 10mhz port would only work on 160-6 meters.

The external clock source drives the radio's master clock, so it is band independent in that regard.

Tim, I know when using the external 10Mhz reference with the 5000a, there was an option to turn it on/off in one of the menus.  Is there anything I need to do to turn on this functionality on SSDR?  I see the GPS tab on the setup menu but it looks like that pertains to the internal GPS option.

Yes, it has to be connected and providing a 10 MHz sine wave signal when the radio is powered on.  That is when the radio looks for a valid click source and it will search for an external source before looking for an internal source (OCXO, TCXO or GPSDO)

Have used one of these for three years on a 6700 with no trouble:  https://fairradio.com/product/gps-ant/

If you use it outdoors make sure your lightning protectors pass DC.

I have the Flex gps unit, in a piece of pvc pipe for weatherproof, outside the window fixed to an awning.  What lightning arrestor would I need to use for GPS freqs?
Last week in a storm, 2 lightning strikes close, took out the cable modem, its powerpack, and 1 fibre media converter, that was connected to it.  Any ideas on a gps arrestor?

Anything with a 3GHZ passband and DC pass will work.  If it's receive-only, power rating doesn't matter.  I use Alpha-Delta but lots of good choices.

Walmart have then for less than 50 dollars. They are meant to be use in a boats.
I bought one and it has been working well in Northeastern Florida for the last two hurricane seasons and lighting.
