Title: WWV 10, 15, 20, 25mHz
Post by: Josh on June 20, 2019, 2024 UTC

WWV 10, 15, 20, 25mHz were all copied @ 1808Z 20JUN19
10 and 15 were strongest, with 20 a close second and 25 in and out of noise level but good enough to set the reference oscillator when they were sending the 500/600Hz tones.

Good work Josh, best I can do this way is 2.5, 5, 10 and 15MHz.  Haven't heard 20 or 25MHz for a very long time due to poor conditions, even 15MHz was not the best.

2.5MHz is plus 20dB over one night/morning and then barely readable the next as conditions on HF very erratic this way.

You make up for missing the 20 and 25mHz wwv by hearing jjy, the Russian time stas, and the Chinese ones, I never get those.
