....last night reception here in California was odd. A rising K-index
apparently resulted in lots of noise and very squirrely propagation, like the ionosphere was randomly red hot and ice cold. For the most part, the lower bands were totally NG - 60/75/90 all were nearly dead through 0700z. 41 and 49 were not much better, with only the strongest big boys punching through, and even then not very strongly. Despite the SFI up to 105, Most stations were a couple S-units below their usual levels, with a few minor exceptions on 25m and 31m. The exception was R. Educacion in Mexico City, 6185 khz. Usually a difficult station here, with low modulation and battered by the big relays on either side of it, last night it outshone them all, with a 20 over S-9 signal, crystal clear fidelity and magnificent steadiness. I have a hard time believing it was propagation alone that did this - but unless they suddenly found a 100-kW transmitter lying around, I'm not sure how they managed this signal. Things are getting interesting :-) |

Things are getting interesting :-) Same here,on the E.Coast ! Propagation varies wildly from great to almost complete zilch, with the exception of the regular ever-present Bible Study stations . . . R.Educacion was always a modest low power broadcast station ( 10kW) , maybe they have raised the power a bit lately . I doubt very much it is a 100kW station . But again , you never know-- we are living in a very Troublesome Times , to say the least . |

But again , you never know-- we are living in a very Troublesome Times , to say the least .- Hide quoted text - - Show quoted text - Last night at 0630z, they were playing beautiful Mexican folk music by a male singer, and then right after the station ID, the female announcer, in her best late night public radio voice, discussed the opera, 'The Marriage of Figaro' and other Mozart items. Then right back to folk music - interesting juxtaposition of topics :-) From the night before to last night, the station signal literally leapt up 6 S- units and was armchair for the first time *ever* at this QTH. |

Things are getting interesting :-) 15 meters was hot in the mid-afternoon yesterday (1800UTC). I contacted a 40 watt SSB Algerian station with 100 watts. 59 report both ways. And I got a 59+10dB report out of Croatia also with 100 watts SSB. Jim(MI) |
