VOA Radiogram for August 29-30
From Kim Andrew Elliott:
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:
1:30 Program preview
2:45 Strife reduces pollution in parts of Middle East*

Thanks for the many

behind in responding, but I will respond!
