VOA Radiogram Weekend Schedule

Hello friends,

VOA Radiogram this weekend will include the Olivia 16-1000 mode with a center frequency of 2000 Hz. If you happen to experience co-channel interference consisting of voice and/or music, the robustness of the Olivia 16-1000 mode in combination with the higher audio frequency might allow a successful decode. At 40 words per minute, Olivia 16-1000 is faster than Olivia 64-2000.

Here is the lineup for VOA Radiogram, program 169, 25-26 June 2016, all in MFSK32 except where noted:

1:35  Program preview
 2:45  Pluto may have liquid ocean*
10:17  Fiery re-entry for junk from ISS*
16:33  Olivia 16-1000 (2000 Hz): Zuckerberg PC security*
22:06  MFSK32: Image, mobile app transmitted by shortwave*
26:04  Closing announcements*

Download apps via shortwave? A recent transmission of a mobile app from shortwave station KTWR in Guam, to a DRM receiver in Thailand, has caused much discussion. See coverage at and The SWLing Post. While DRM offers more bandwidth and faster download speeds than the VOA Radiogram method of digital modes via analog radio, VOA Radiogram data can be received on any radio.

Software to decode VOA Radiogram includes Fldigi from and, for Android devices, TIVAR.

Thank you for your reports from last weekend. Reception conditions were generally good, so the Olivia 64-2000 did not get much of a workout. Decodes were good even in Perth, Western Australia.

A reminder that Fldigi saves decoded MFSK images as .png files in the folder \fldigi.files\images\.  If convenient, please attach those .png files to your reception reports.

I hope you can tune in and write in this weekend.
