Re: [time-nuts] WWVB odd propagation 07/14/2013
Thanks Alan for the clue. I had not seen this behavior before. Now if it would behave like this all the time I would not need AGC. I can only hope. :-) Or my AGC is so good its controlling the entire LF spectrum.

Re: [time-nuts] WWVB odd propagation 07/14/2013
Hi Paul a major geomag storm occured around midnight UTC on the 14/15th. This precipitated hot electrons into the D-region which causes extra attenuation at night and enhanced daytime long distance signals. The daytime effect is usually short lived but the night-time absorbtion may continue for a few nights, as the ionoshere exchanges charge with the Ring Current (Van Allen belts) Alan G3NYK - Original Message - From: "paul swed" To: "paul swed" ; "Time-nuts" Sent: Monday, July 15, 2013 2:56 AM Subject: [time-nuts] WWVB odd propagation 07/14/2013 Well this is pretty strange.

The Earth's geomagnetic field has been unsettled (K=4) and the Solar Wind magnetic field has been negative (energizing) all day. Could be a setup for a big kick.
