updated list of planned passes for DM23/DM24 on 13 July
by Patrick STODDARD (WD9EWK/VA7EWK) 13 Jul '12

13 Jul '12

Hi! Guess I need to slow down a little when plotting passes to work. Here are the passes I plan to work tomorrow (Friday, 13 July) at the DM23/DM24 grid boundary in western Arizona: 1811-1828 UTC on FO-29 1845-1849 UTC on AO-27 1955-2015 UTC on FO-29 2023-2030 UTC on AO-27 2141-2157 UTC on FO-29 2204-2211 UTC on AO-27 The first of the AO-27 passes listed above will only have 2 degrees of maximum elevation around 1846-1848 UTC. The repeater is scheduled to switch on at 1842 UTC, so I will not hear the first few minutes of the 7-minute repeater time. Since the afternoon temperature should approach 110F/43C out there, I expect to be "commuting" between the grid boundary and Quartzsite (about 25 minutes south of the boundary, along the I-10 freeway) to be able to stay in my car with its air conditioning. :-) 73!

When JFK Met Telstar
by Clint Bradford 12 Jul '12

12 Jul '12

Fifty years ago today, the little Telstar satellite relayed the first TV transmission across the Atlantic. It wasn't long before President Kennedy had his black-and-white electrons beamed from the U.S. to Europe. http://maccentricity.blogspot.com/2012/07/when-telstar-met-jfk.html >From cNet.

A little problem in EL60
by Omar Alvarez 12 Jul '12

12 Jul '12

On Saturday 14th I will be on Xcaret park (EL60), there is a possibility that the security people do not let me in with the Arrow antenna, so I will try with the telescopic antenna of my FT-60R. I will check activities and back to EL60 for one or two passes. I will email again when I am sure about the day and pass. Regards Omar XE1AO DK89df ******************************** M.C.

WD9EWK @ DM23/DM24, Friday (13 July)
by Patrick STODDARD (WD9EWK/VA7EWK) 12 Jul '12

12 Jul '12

Hi! I plan on making a quick drive west toward the Colorado River and operate from the DM23/DM24 grid boundary for about 3 hours starting with an AO-27 pass around 1842 UTC. I only have 3 degrees of elevation on that pass, but the later pass at 2023 UTC will be better. I also plan on working one or two FO-29 passes from out there, with the first FO-29 pass coming around 1900 UTC. I've been out to this spot before, about a 30-minute drive north of the I-10 freeway and the town of Quartzsite in very rural La Paz County. I should have APRS running for this drive. It should be visible at http://aprs.fi/wd9ewk-9 if there are no problems. There are good mountaintop digipeaters along the entire drive outside of Phoenix, so this shouldn't be a problem. I will also post updates to my Twitter feed @WD9EWK (visible at http://twitter.com/wd9ewk for those not using Twitter), and - if possible - an additional post to this list once I am out there. I will be happy to send QSL cards to those who work WD9EWK at the grid boundary. There's no need to first send me a card or SASE. Just e-mail me the QSO details, and - if you're in the log - I will mail a card. I will also upload QSOs to the Logbook of the World. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

X-FLARE! Big sunspot AR1520 unleashed an X1.4-class solar flare on July 12th at 1653 UT. Because the sunspot was directly facing Earth at the time of the blast, this is a geoeffective event www.spaceweather.com Damon WA4HFN
