    In 1924 the construction of Grimeton Radio Station in Sweden was completed and the two transmitters, invented by Ernst F.W. Alexanderson was put into commercial operation. The radio station call sign was SAQ.

    SAQ is the only remaining pre-electronic radio transmitter that has been preserved and is still functional, event though only one of the original two transmitters remain.

    Test Transmissions
    There may be some test transmissions, preliminary on October 23rd between 13:00 - 16:00 CEST. During the tests, SAQ will be on air shorter periods of time, when we will be carrying out some tests and measurements.

  • Amateur Radio Daily will Attend Zero Retries Digital Conference and Pacificon

    Amateur Radio Daily (and Amateur Radio Weekly) will attend Zero Retries Digital Conference (ZRDC) and Pacificon October 16th through October 18th. My name is Cale (K4HCK) and I produce both publications. I'll be speaking at ZRDC about New Tech Hams, an emerging group of hams that are highly focused on digital communication and the software that powers it. Thanks to ZRDC for the invitation! I think this talk will be a lot of fun.

    Tickets are still available for ZRDC both for in-person and Zoom based attendees. ZRDC focuses on technical innovation in amateur radio. The speaker line-up includes representatives from FreeDV, DigiPi, M17, and more. Learn more about ZRDC.

    I will also be attending Pacificon and will share a booth with Zero Retries. Stop by booth 33 and say hello! I look forward to meeting you and hearing your feedback. Tickets for Pacificon are also still available.

    73 and thanks for reading!

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
Written by Administrator   
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

  • Will RADE Be the Next SSB?

    It’s been a half century since single sideband (SSB) supplanted amplitude modulation (AM) as the most popular voice mode on HF, due largely to its spectrum efficiency, occupying roughly half the bandwidth of an AM signal. Now, there’s a new digital voice mode from FreeDV called Radio Autoencoder, or RADE, that occupies half the bandwidth of an SSB signal and reportedly provides more natural-sou...
