Hi Poul-Henning --
I'll be able to capture at least two HF frequencies simultaneously if
you'd like, with SSB reception and audio recorded to a sound card. I'm
not sure if WWVB will be strong enough with that system to decode; I'll
try to log some of it ahead of time and send it to you to see if it'll
work. Otherwise, I can do WWV on 5 and 10MHz, which are the most likely
to have propagation heree at that time of evening.
I'll also be able to log the messages from the Z3801A and whatever data
I can dump from the Spectracom 8164 WWVB receiver.
