VOA Radiogram, 21-22 and 28-29 May 2016

I have prepared the next two editions of VOA Radiogram in advance, so they will not include any up-to-date news items. They will, however, be interesting shows …

Program 164, 21-22 May 2016 will begin with an MFSK32 introduction, then transmit the same VOA Science World item about boiling water on Mars in Olivia 64-2000, Olivia 32-1000, and Olivia 16-800. 

This will be a chance to compare the performance of these three modes, which all have speeds in the 20-30 wpm range. The program will conclude in MFSK32 with an image and closing announcements.

Program 165, 28-29 May 2016 will consist of six science images from the VOA Science World Blog. All of these will be in MFSK32, although the sixth, showing a Falcon 9 rocket launch, will be transmitted in both MFSK32 and MFSK64. Images in MFSK32 and MFSK64 require the same amount of time to transmit; the MFSK64 image has more resolution but is more susceptible to interference. After the MFSK64 image, VOA Radiogram will return to MFSK32 for closing announcements.

Please send reception reports to .
