Lots of Solar Flares....

Space Weather report solar activity is high. In just 48 hours, monster sunspot AR2192 has produced a series of seven M-class solar flares of increasing intensity

The eruptions crossed the threshold into X-territory with an X1-class flare on Oct. 22nd. NASA's Solar Dynamics Observatory recorded a powerful flash of extreme UV radiation in the sunspot's magnetic canopy at 14:30 UT.

Remarkably, not one of the explosions so far has hurled a significant CME toward Earth. The primary effect of the flares has been to ionize Earth's upper atmosphere, causing a series of short-lived HF radio communications blackouts. Such blackouts may be noticed by amateur radio operators, aviators, and mariners.

Earth-effects could increase in the days ahead. AR2192 has an unstable 'beta-gamma-delta' magnetic field that harbors energy for powerful explosions, and the active region is turning toward Earth. NOAA forecasters estimate at 65% chance of M-class flares and a 20% chance of X-flares during the next 24 hours.

This and That....

Gary K9AY checks in with an update of his popular low-band receiving loop. "I've done a lot of analysis and experiments over the past couple years that are not yet published. Among the results is a better understanding of the role of ground. I now recommend a few radials for all installations: a minimum of (4) and preferably (8) radials that are twice as long as the loop's footprint. If you add them to an existing system, remember that the resistor should be readjusted for deepest null."

If you need an outdoor grease that won't attract dust and grit, Mike KD5KC recommends Super Lube. This silicone-based, Teflon-impregnated lubricant might be just the thing for tower winches, bearings, and other exposed uses. http://www.super-lube.com/



What connector is that, anyway? The wireless world has moved quite beyond the UHF/BNC/N world so Pasternak has prepared this connector identifier chart. https://www.pasternack.com/images/pdf/7%20Connector%20Identifier.pdf



Ralph Fedor K0IR has posted a very interesting video to YouTube that introduces newcomers to DXing, DXpeditions, and Amateur Radio in general. See Video: https://www.youtube.com/watch?v=k4dJcK-WVRw&feature=youtu.be
(Thanks, Daily DX)

WOM HF-Transmit Antenna Farm....

Hams might appreciate this map of the WOM HF-transmit antenna farm
( http://rightime.com/HF/P1030367aa.JPG ) operated by AT&T for many years in Pennsuco, Florida, west of Miami. This was one of three high-seas ship-to-shore and island telephone service stations ( https://en.wikipedia.org/wiki/AT%26T_High_Seas_Service ). WOM's corresponding receive site was in Plantation, near Fort Lauderdale. When it was decommissioned the transmission facility sported 38 log-periodics, rhombics and omni verticals over a half-square-mile of Everglades, each of which could handle 10kW from any of 20 or so mostly-Collins transmitters ( http://rightime.com/HF/PennsucoList.pdf ).

Thanks, Tom Becker, ex-KN3URO
