Hi all

Just recorded some TA beacons last night (00:36 UTC 23 dec 2005) with my stand-alone AR5000A+ receiver (no external freq standard).
The stability on QRSS60 is quite good.
However, the receiver drift became 3/10th of Hz within 10 minutes when I entered the shack. Please note the receiver was set to LSB (NA is on the top of the picture, and XES at the bottom). The large white line comes from a local synthesizer used as marker on 137,7775.

The propagation was quite good last nite: a 10 dB attenuator was let inserted (by error !) between antenna and the receiver.

Rig:
23 turns 1,1 m square loop 10 m high
Single turn coaxial coupling to 50 ohms receiver input
10 dB attenuator
AR5000A+ receiver
Argo software
