Anyone who is using one (or both) of these, and/or folks who have a
logical opinion:

There's more... but this is a good start. Just want to try and get
parts on the way. Have to build a separate outboard regulator for the
timing GPS antenna, too.
Thanks!

=============================
Clay,
I have all three of these units, all powered off USB. I don't see any
reason why you shouldn't use a USB cable with just the DC part connected, so
that there's no issue about radiation. A standard USB port would only
supply 0.5A so that's an upper limit on the power consumption. If it's a
very long USB cable (you mention mast-head) check the resistance.
As a crude guide...
- The (larger box) NTP server feels cold to the touch.
- The smaller, single output frequency source feels very slightly warm to
the touch (feeding an Icom IC-R8600)
- The larger, dual-output frequency source feels slightly warm to the touch.
There's an e-mail address where you could ask: support at leobodnar.com
Cheers,
David
