...WWV is not the end-all technology for getting time by radio...
As a SW-listener I can confirm that WWV is not easy to listen to - from my QTH (of 60°N 30°E). Their time-ticks are quite discernible at times but their voice messages are far too weak. My guess - they use the worst modulation available: AM. If they had a properly compressed voice over SSB - the usable range of their transmissions would be much wider. Even DSB with an unmodulated carrier (for compatibility with valve/tube-radios!) is more preferable.
My rig is Sony ICF-SW100 and a 5-meter long wire "antenna".
When there is a propagation - I do hear them at 10MHz and 15 MHz, at 5MHz they are squarely under the BPM's loud transmission.
