  • Cadenza Brings Morse Listening and Sending Practice to iOS and Android

    The following is a press release from Cadenza:

    Cadenza is a Morse code training app from independent developer Ivan Terekhin of Trifoil Trailblazer. Available for iPhone, iPad and Android, it combines introductory character practice with exercises for people preparing to use CW on the air.

    The trainer uses the Koch method with Farnsworth spacing. Learners begin with two characters, hear them at speed with wider gaps, and add more as their accuracy improves. Practice works offline and does not require an account.

    The free version includes alphabet, number and punctuation training, a reference covering prosigns and Q-codes, a two-way Morse translator, and a microphone decoder for clean Morse tones. Daily challenges and progress tracking are also included.

    Optional Cadenza Pro adds callsign practice, simulated QSOs, pileups, head copy and sending practice. Users can create custom practice lists for callsigns and contest exchanges. Sending exercises support an on-screen key or a straight key or paddle connected through a compatible USB or Bluetooth keyboard adapter, such as VBand or Vail.

    Cadenza is free to download, with optional monthly, annual or lifetime Pro purchases.

  • Pocket Shack Brings AllStarLink to iPhone, iPad, Mac, Apple Watch, and Carplay

    The following is a press release from the authors of Pocket Shack:

    Find a node, listen in free, and key up from your phone, your wrist or your dashboard.

    DALLAS-FORT WORTH, Texas, November 2026. Cygnus Strategy has released Pocket Shack, a native AllStarLink client for iPhone, iPad, Mac, Apple Watch and CarPlay, now on the App Store.

    Listening is free

    Connect to any node that allows app connections and listen with no microphone involved. Monitor-only connections never transmit. Pocket Shack shows which nodes are on the air right now. It searches the full node directory by number, callsign or place, even offline, and puts every node on a map or lists the ones nearest you. Node details show what a node is linked to, its frequency, location and activity. Callsign lookups use your QRZ subscription if you have one.

    Keep the nodes you use most a tap away, each with a live talking or idle badge. Give any node a name and a note, and they sync to all your devices. Pocket Shack keeps listening with the screen locked and over Bluetooth, and reconnects when you move between Wi-Fi and cellular. If a node doesn't send its own courtesy tone, an optional local beep marks the end of each transmission.

    Talking is Pocket Shack Pro

    Hold to talk, tap to toggle, or go hands-free with voice activation and a live sensitivity meter. Pocket Shack shows when the node has the channel and waits for it to clear before you transmit. A transmit timer counts down so you don't time out the repeater. A mic gain meter tells you if you sound too quiet, just right or too hot. Pro also adds a DTMF keypad for node commands.

    Wherever you are

    • CarPlay: big, simple controls for favorites and nearby nodes, with Talk by tap or by voice.
    • Apple Watch: pick a favorite and hold to talk with your iPhone in your pocket. A ring counts down your transmit time. Distinct taps on your wrist tell you when the channel clears, when you're on the air, before the timeout and if the link drops. Apple Watch Ultra's Action Button can key up.
    • Mac: a real Mac app with a menu bar control, a global push-to-talk shortcut and your choice of microphone and speakers.
    • Hands and voice: the call Mute control on the Lock Screen, in CarPlay or on AirPods starts and stops transmitting. Siri can connect you ("Call node 46308 with Pocket Shack").

    An all-red Night appearance protects your night vision in the shack. Pocket Shack works with VoiceOver and large text, and it has no ads, tracking or analytics.

    I built Pocket Shack because I was already checking into nodes from my phone while walking the baby, changing diapers and doing things around the house. Most of my time on the air is on the drive to and from work, so I wanted the car to be a first-class experience too. I love my radios, but Pocket Shack makes ham radio fit into a busy everyday life. -Jonathan Roemer, KA1PID, founder of Cygnus Strategy.

    Availability

    Pocket Shack is a free download on the App Store, and listening is free. Pocket Shack Pro is $1.99 a month, $14.99 a year with a 7-day free trial, or $39.99 once, and Family Sharing is included. Pocket Shack isn't affiliated with AllStarLink, Inc.

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

  • The ARRL Solar Update

    Solar activity is expected to be low in the coming days, according to NOAAís Space Weather Prediction Center, with a chance for M-class

    flares and a slight chance for stronger X-class flares associated with sunspot region 4566, which is showing rapid growth in both size and magnetic complexity. No Earth-directed coronal mass ejections have been observed. Sunspot numbers are increasing from a low...

  • The ARRL Solar Update

    The active sunspot region that has been giving us improved
    propagation over the past several days will be rotating away
    from Earth’s view today, but conditions on most of the HF
    amateur bands should remain pretty decent in the days ahead,
    as the 10.7-centimeter radio flux remains right around 100.
    However, NOAA’s Space Weather Prediction Center (SWPC) says
    the geomagnetic field could become unsettled...
