Another thing to consider: Depending on how well you shock-mount the fan,
what if its vibration translates to sideband spurs or noise?

Hello Murray,
no problem :) just wanted to make sure folks know that there are options
below 5W out there.
I am impressed with your 50mW TCXO unit. We've been thinking about offering
DIP14 TCXO's as well on the FireFly. That would allow for true battery
operation.
We are also testing
Alberto,
In the commercial world that the Z3815A's (and quite possibly the Z3801
etc) were used in, they were installed vertically at the bottom of a
large equipment cabinet that had convection air channels running within
it. A bank of 12-16 fans towards the top of the cabinet sucked up

magnetic circuit with the minimum reluctance axis displaced from the

of the energised field.
When activated the 2 pole magnetic rotor aligns with the magnetic

Yup, got it on my oncore as well:
NTPns show oncore 0
serial port = /dev/cuad5
state = 12
Same here.

How are leap seconds declared?
The International Earth Rotation and Reference System Service (IERS)
observes the Earth's rotation and nearly 6 months in advance (January
and July) a Bulletin C message is sent out, which reports
