Solar Cycle 24 May Have “Double Peaks,” Says NASA Solar Physicist

According to NASA, the current solar cycle — Solar Cycle 24 — should hit its “solar max” sometime in this year, but so far, solar activity has been relatively low. According to an article by NASA’s Dr Tony Phillips, this period of quiet has led some observers to wonder if forecasters missed the mark. But solar physicist Dean Pesnell of NASA’s Goddard Space Flight Center has a different explan…

Portable Yagi / Beam Antenna for VHF / 2m HAM Radio Part 1of 2

Part 1of 2 I took this video showing the antenna in action and how directional it is. (Which is what you need to concentrate the radios power in one direction). In the video it shows me in my back yard transmitting 5w (146.835mhz) to a repeater that is located about 40 miles away at 6300′ elevation. I am located at about 1400′ elevation and there are hills directly between the repeater and me, so with a rubber duck I would not have been able to make contact. Buy one of these awesome super-portable light weight antennas for only .95 on eBay! Check out the link below (to eBay) for further info. cgi.ebay.com

QRP CW FUN WITH 2012 ARRL 10M CONTEST

Here is an (obviously) unrehearsed excursion into 10 meter QRP. With about average solar conditions (WWV#’s=104/3/1), I turned the power down to 4 watts on my Elecraft K2 (to tribander @ 36ft), flipped on my web cam and commenced to do a bit of search and pounce during the ARRL 10 meter contest. Starting at the bottom of the band and tuning my way to 28.023, I worked 9 stations in N and S America in about 10 minutes.* NOTE*: As Jorge’s comment points out: I mistakenly gave CW5W’s call as “CW4W” – one of several errors in my video narrations – ’tis one of the drawbacks of posting unedited clips.. I have some nice keying fumbles as well, “WYSIWYG”.
