Hello friends,
In last weekend’s
experiment comparing Scottie DX SSTV and MFSK32 images, the MFSK32
images generally were clearer, but the Scottie DX images usually had
less slant, probably because of the slant-correction
capabilities of the decoding software. I will, eventually, compile a
gallery showing several comparisons.
[That was the experience here. MMSSTV did correct a slight slant, but it had more noise in the image. -Hugh]
There will be no
SSTV in this weekend’s program, but if you are interested in more SSTV
tests, let me know, and we can include them in future shows.
This weekend’s
program will include one item in Olivia 32-2000. This will be
interesting if you experience poor reception conditions because of
propagation, local noise, or a less-than-top-quality radio.
In Fldigi, Olivia 32-2000 requires a custom mode selection: Op Mode
> Olivia > Custom: Tones: 32, Bandwidth: 2000. I provide 20
seconds for you to make this change. However, Olivia 32-2000
does have an RSID, so it will probably do all the work for you.
Here is the lineup for VOA Radiogram, program 115, 13-14 June 2015, all in MFSK32 except where noted:
1:36 Program preview
2:47 New NASA photos of dwarf planet*
7:22 Mars landing device parachute test fails*

25:13 Closing announcements*
28:30 Hell 80: Bonus mode of the week
