VOA Radiogram, program 45, 8-9 February 2014

Hello friends,

Last weekend's experiment with the simultaneous transmission of MFSK32 text and images was mostly successful. We'll try it again this weekend on VOA Radiogram.

The procedure will be the same. You can decode the two streams sequentially from your recording. Or you can run two instances of Fldigi, as follows:

1) In both instances of Fldigi, turn the RxID on (green).

2) An RSID for MFSK32 at 2100 Hz will be transmitted, moving both instances of Fldigi to an audio frequency near 2100 Hz.

3) On the second instance of Fldigi, turn the RxID off.

4) An RSID for MFSK32 at 1500 Hz will be transmitted, moving your first instance of Fldigi back to an audio frequency near 1500 Hz.

5) Test will be transmitted centered on 1500 Hz, and the images centered on 2100 Hz.

6) After the dual MFSK32 transmissions, you can turn off or minimize your second instance of Fldigi.

The Winter SWL Fest will be March 14-15 in suburban Philadelphia. I plan to be there to demonstrate the decoding of text and images from VOA Radiogram. More information at swlfest.com. Register in advance or walk in.

I'll now turn my attention to answering your reports from last weekend.
