Hi A lot depends on just how much trouble you want to go to. The TBolt is indeed a reasonable solution, it's overkill, but it will do everything you want to do. A free running Efratom LPRO 10 MHz rubidium also would do everything you need to do for a bit less money and a bit less hassle. A th

Don, A GPSDO would suit you fine, perhaps a Thunderbolt as that seems to be well know and respected here, and is a relatively inexpensive way to get a GPS disciplined oscillator. There is plenty of coverage of sats in NZ, I'm in Christchurch and daily track up to 12 on a Z3805A at any one time. Y
