Thanks for the heads-up Peter.   That makes three
recommendations I've had for this seller.

I expect I'll order one or two of these 'timing grade' GPS,
likely a Thunderbolt.  I still want to see what can be done
with 'commodity' GPS devices, but having a proper one as a
reference standard would be nice.

Reassuring, thanks.  Although I see he's advertised a rubidium
clock to 'Enhance the sound quality' of CD, so have doubts now :))

PS I spoke to a chap at Garmin support about the slow cyclic
drift of the GPS16X and he asked me to send details. We'll
see what comes from that.
