Hi Didier,

I' building a multi frequency beacon based on QRP-labs U3 beacon kit. It 
has the ability to discipline its oscillator with a PPS input and, using 
NMEA input, set and maintain time and location for exact control of WSPR 
and OPERA modes of operation.

As it currently only accepts NMEA input I was wondering there was a way 
to get NMEA out of a thunderbolt. I've lodged an RFE with the developer 
to add TSIP support to the U3, but I don't think that's going to happen 
anytime soon.

I'd rather use the Thunderbolt as the time and PPS source since its way 
more accurate than the LEA-M8FGPS module that optionally comes with the kit.

I'd like to use the U3 as the basis of beacons all the way to 10GHz and 
the Thunderbolt is a superior device for locking such things and 
supplying the base 10Mhz to lock the appropriate LO's.

thanks

Tim
