  • Icom Receives Good Design Award

    Icom has received a Good Design Award for its latest ID-5200 transceiver.

    The Good Design Award judges outlined three reasons for choosing the ID-5200:

    1. Equipped with independent dials for left and right, enabling intuitive operation when receiving two waves simultaneously.
    2. A modern design centered on a color touchscreen, blending seamlessly with car interiors.
    3. A separated main unit/controller structure and a variety of mounting options make it adaptable to any installation environment.

    The Good Design award describes itself as:

    [The] only comprehensive design evaluation and promotion mechanism in Japan. Together with G Mark, it has been recognized by a wide range of people for nearly 70 years, and has continued its activities to make people's lives and society better through design.

    This is the second year in a row that Icom has won the award. Last year the Icom IC-7760 took home a Good Design Award.

  • HAARP to be Active for INFUSE-II and DUST-III Rocket Sounding Missions

    The following is a press release from the University of Alaska Fairbanks Geophysical Institute:

    The High-frequency Active Auroral Research Program (HAARP) will be conducting a research campaign October 20-24 UTC, with operating times specified in the table below. Operating frequencies will vary, but all HAARP transmissions will be between 2.8 MHz and 10 MHz. Actual transmit days and times are highly variable based on real-time ionospheric and/or geomagnetic conditions. All information is subject to change.

    These transmissions are being conducted in support of the INFUSE-II and DUST-III sounding rocket missions launching from Poker Flat Research Range, located north of Fairbanks, AK. INFUSE-II will test a new type of ultraviolet imager for use on future space telescopes, while DUST-III will carry a miniature laboratory into space to study how tiny grains of space dust form and grow.

    For more information on both missions, consult the UAF Geophysical Institute's webpage for the upcoming launches: https://www.gi.alaska.edu/news/stellar-insights. The rocket launches will be livestreamed on YouTube at: https://www.youtube.com/@pokerflatrr.

    Note that due to the need to make real-time schedule adjustments based on ionospheric conditions and to coordinate with the rocket launch teams, no frequencies are specified in the table below. The included transmission notice supplement contains information on the frequencies HAARP is authorized to transmit. HAARP transmissions will only occur on our authorized frequencies. There are no specific data collection requests from funded investigators, but reception reports are appreciated and may be submitted to our online form at https://haarp.gi.alaska.edu/form/reception-reports.

BASE 40 Flight October 8, 2009 PDF Print E-mail
Written by Administrator   
Friday, 09 October 2009 09:19

BASE 40 was successfully completed today.

Launch was about 8 minutes late in a light rain. 

Launch at 1218 UTC from southwest corner of track around football field.  Had good visual of the ascent for nearly ten minutes.

Burst at 88000 feet at 1319 UTC (average ascent speed of 1440 ft/min).  Occurred over the southwest corner of Greenfield, IN. 

At 62000 feet at 1323 UTC a catastrophic event occurred during post-burst chaos.  The APRS unit remained attached to the parachute, but one of the swivel connectors opened and the remaining string was cut by the carbon fiber tube released the 900 MHZ command pod, DominoEX, geiger counters, video cameras, and photometers.  With no chute, these boxes landed in a field southwest of Knightstown and northwest of Carthage, IN.  Impact occurred at 1334 UTC and the flight data recorder indicated a speed of about 48 miles/hour 200 feet above the ground.  Maximum descent speeds in the free fall reached 120 miles/hour.

With the reduced load, the parachute and APRS unit landed east of Richmond, IN at 1410 UTC in a soybean field about 2.5 miles east of the Indiana-Ohio state line between US 35 and I-70.

I will examine the video for additional details on the separation event.  This initial analysis comes from flight data and analysis of the payload strings.

Thanks again for your support,
Howard

P.S. - I know that Bill Brown would appreciate any feedback from those that attempted to receive the Domino EX signal.

 

 
BASE 34 Flight March 12, 2009 PDF Print E-mail

Monday, 16 March 2009 11:53

BASE 34 was successfully completed today.

Launch: 13:52 UTC from DePauw
Burst: 15:20 UTC at 103,800 feet
Landing: 16:12 UTC between Potsdam and Laura, Ohio (39deg 58.78 min North, 84 deg 24.77 min West)

We had a visual sighting on the descent for the last two minutes. Smooth landing in the top of four trees about 60 feet above the ground. Retrieval was accomplished with the EZ Hang slingshot system using the tennis ball as the projectile. (Only took 4 attempts, with the first two being miserable failures due to operator error by me.)

The StratoStar system sent all the flight data to the mobile tracking station in real time.

Landing support from Ron, N9QGS, and Justin,W1IX.

Additional details will follow on www.depauw.edu/acad/physics/base

Thursday, 15 January 2009 17:01

The BASE 32 flight was a success. Launch at 16:20 UTC from DePauw campus (39.64
North, 86.86 West) by a rookie crew in 20 mph winds. Average ascent rate of 1470
feet/min. Burst at 17:18 UTC 85,000 feet. Landing at 18:02 UTC at 39.774
degrees North and 85.055 degrees West longitude. Flight heading 84 degrees from
launch to landing. Great circle distance 97 miles.

Recovery made by Justin Munger, W1IX.

Excellent realtime flight data from student experiments.

Details to follow on the website: www.depauw.edu/acad/physics/base

BASE 33 is still on schedule for Saturday 17 January.

  • Florida Hams Provide Communications Support During Hurricane Isaias

    Amateur radio operators from Florida’s Santa Rosa, Nassau, Lake, Pinellas, and Leon Counties played an important role in supporting emergency communications efforts during and following Hurricane Isaias, helping ensure that critical communication capabilities remained available throughout the storm.

    In Santa Rosa County, volunteer amateur radio operators staffed the Emergency Operations Center (...

  • The ARRL Solar Update

    Look for improved propagation on the upper HF bands, as both the
    sunspot numbers and 10.7-centimeter radio flux remain near or above
    100. According to NOAA's Space Weather Prediction Center (SWPC),
    the increase in activity is being fueled primarily by sunspot
    Region 4551, which is described as the largest and most complex of
    six sunspot regions currently visible on the surface of the Sun.
