VOA Radiogram, 25-26 February: Three flavors of MFSK
With reception conditions apparently improving, we will take a chance with MFSK64 (240 wpm) for one of our news stories this weekend.
But if reception conditions are poor, we will also transmit one story in MFSK16 (58 wpm). Tuning for MFSK16 needs to be precise, so if the RSID does not work, I precede it with a 10-second tuning signal.
So this will be a weekend to compare MFSK16, 32, and 64, including one image transmitted in both MFSK64 and 32, and another image transmitted in both MFSK16 and 32.
Here is the lineup for VOA Radiogram, program 204, 25-26 February 2017, all in MFSK with baud rates as noted:
1:59 MFSK32: Program preview
3:10 MFSK64: Astronomers discover “new earths”*
8:06 MFSK32: Image* and HAARP experiment*
16:28 MFSK16: Arctic seed vault*
22:44 MFSK32: Image* and closing announcements*
* with image
Please send reception reports to radiogram@voanews.com.
