I wish I could have heard JJY.  When I listen to remote SDRs in Japan now I either hear the Chinese station BPM, or WWVH.

My new job is as Director of Engineering at WWVH, so I'm glad we get in there to compete against the big signal from BPM.

Regarding the BBC time pips...  One time I was visiting BBC World Service and I was in the control room as the the top of the hour approached. As a fellow broadcaster, I got to pot up the time pips signal on the audio console - very cool.  Later I was in the control room again and I got to pot up the audio from Big Ben.  These were real highlights for me, a lifelong BBC World Service listener.
