I paid $36 for two Motorola Oncore receivers. These are 55 nanosecond (1 sigma) timing receivers. I think today they cost about $25 each. I paid $27 for the timing antenna that is a helix the inside a pointed redone. The dome has screw holes that fit a common galvanized pipe flange. This is not an expensive setup and the parts are all there on eBay. You need to add a power supply. I use a plug-in power cube. But as I said. Use what you have all GPS receivers have more precision than NTP can make use of. You don't need high-end gear if the requirement is only "sub millisecond". Mostly I'd say don't spend money on performance you don't need but in some cases you get great performance for less money. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
