Yeah... of the country. I'm on the
East coast. Propogation not so swell
out here. But stilll, that doesn't
explain why the signals don't come
in like they used to, while I still get
other programming between 2.5 and
30 mHz. (That's what written on my
RADIO DIAL - don't know if it's correct)

Another thing to consider is that nearly all the strong SW signals in
the US are now domestic broadcasters. The old school SW broadcasters
were usually an ocean away. They're mostly gone now but there are many
high power domestic transmitters which can put out a huge signal.

So, if Radio Sweden or Swiss Radio International were still broadcasting
to the US, they might well be now lost in the noise at your location.
But Brother Stair buys time from high power SW transmitters right here
in the US.

Something I never thought of: Most of these
official time transmitters are west of the
Mississippi. I live on the east coast. No
frickn wonder! :(

Dear NIST: provide us east
coasters with better shortwave reception of
these signals!!

Never (unless there was an actual radio blackout) had any trouble
hearing them here in the great midwest. What kind of antenna/receiver
are you using?

If you *really do* need a time signal closer to you, try CHU in Canada.

Big difference between Indiana and the northeast coast! We're
practically at opposite ends of the country from Ft. Collins CO.

So increased RFI is only part of the issue: Shortwave time
transmissions reach only the western 2/3 of the lower 48 states!

I think this has just been another sign of poor band conditions. It's been a
while since I've heard WWV reliably here too, but the solar flux during that
time has been in the 70's. Now that it's sitting at 86 the past two days:

1335z (8:35 AM local) : WWV at S-9 on 5 MHz, S-7 on 10 MHz, and S-5 on 15 MHz,
although with frequent QSB into the noise level on all three freqs.

That's on my backup receiver (DX-394 with 30 feet of wire outside eight feet
above the ground). I've got the dipole for my TS-450 taken down for maintenance
right now or I'd probably have it at S-9 +40dB or better right now using that.
