Hello friends,
This weekend’s VOA Radiogram
will include an experiment suggested by Mark Hirst in the UK. Mark notices that
interference to MFSK images comes from RF noise that is concentrated in the
lower audio frequencies. He wants to know if images might be clearer if they are
transmitted at a higher audio frequency.
Because of a few extra minutes
in this weekend’s program, the third image will be transmitted a second time, at
a center frequency of 2000 Hz.
Here is the lineup for VOA
Radiogram, program 126, 29-30 August
2015, all in MFSK32 except where noted:
