Fellow clockers,

	I just got done reinstalling my TrueTime NTS-200 network time server in a different rack. This required, among other things, installation of a new antenna on the opposite side of the house from where my original one is.

	The new antenna was a Symmetricom/HP 58532A, which requires 5V bias. Unfortunately, the NTS-200 was designed to supply 12V, and there is no easy jumper or software setting to change that.

	So -- After a bit of work, I came up with a minimally-destructive hardware modification to change the +12 feed to +5.

	If anyone else owns an NTS-200, and you've been wanting to use it with a 5V antenna, drop me a note and I'll be happy to send you pictures and details.

	Fair warning: It requires fine-point soldering, a bit of wire-wrap wire, and a lot of patience.

	Keep the peace(es).
