Hi Chris,
Just like last year. They all were QRT for some weeks, probably for
maintenance purposes or to save the energy, HI.
The Alphas are OFF too, since yesterday.
I'm using a cheap GPS module
(http://cgi.ebay.de/Jupiter-Rockwell-TU30-D420-031-GPS-Empfanger-/180713452906?pt=DE_GPS_Navigationssysteme&hash=item2a135c756a)
which has a 10 kHz locked Ref frequency output. It runs 24/7 without
problems for longer than a year now...

VLF,
GQD has been off since yesterday morning around 8 GMT. I've been using
it as a reference to lock my (V)LF grabbers to as I'm sure many others
do. Have switched now to DHO38 despite it's morning break period.
Looks like a local generated reference signal from a GPS receiver is
mandatory for 24h operation and will be implemented in my next receiver.
Anybody has more info about possible maintenance schedule for GQD?
