Satellite reception on you Walki-Talkie(!!!)  fellow space travelers.

The International Space Station (ISS) is having a special Slow-Scan-TV (SSTV)  Robot-36 mode broadcast-download event all this weekend...
  • Start Friday 5/08 at 10:30z  (6:30 am ESDT)
  • End Tuesday 5/12 at 16:40z  (Noon:40 ESDT)
  • There is a 6-1/2 minute, near-overhead, pass:
    • Friday Evening (tonight) with AOS at 9:01 pm local
  • Tracking: SW: --> Overhead --> NE   (horizon-to-horizon)
Inline image

  • UHF Frequency:   437.550 MHz +/- Doppler
  • Approaching Doppler is (+) 10 KHz, then (+) 5 KHZ
  • Departing Doppler is (-) 5 KHz, then (-) 10 KHz
  • LOS 9:07 pm
The ISS will be continuously transmitting a SSTV picture in Robot36 Format.  You can record the audio for later use, or download the Robot App for your cell-phone and let the microphone pick-up the audio and display the picture live.

Best Practice:
- Program five (5) frequencies into your HT's UHF receiver.  Then conveniently switch between them as the pass progresses between the Doppler zones.  (All this in just 6 minutes)
  • 437.560   First Approaching
  • 437.555   Mid Approaching zone
  • 437.550   Overhead zone
  • 437.545   Mid Departing zone
  • 437.540   Last Departing

If you have Satellite tracking software, there are more pass opportunities to explore.  Navigate here to visualize the referenced events.. Enter "Tampa" for the city designation. Then, click on the event box you wish
