Olivia test in SW Radiogram for 7/15-16

Pardon the font weirdness.  I don't know how to fix this.

From Kim Andrew Elliott:

Hello friends,

If you a Facebook user, Al Holt in Florida maintains a Shortwave Radiogram Facebook group here:  https://www.facebook.com/groups/567099476753304 . This is in addition to the Shortwave Radiogram Twitter account: @SWRadiogram . You do not need a Twitter account to follow along: just visit https://twitter.com/swradiogram during the weekend to see results posted by listeners.

I was amazed how well the MFSK64 (240 wpm) performed last week, even under some marginal conditions. You can see videos of reception and decoding via this link: https://twitter.com/SWRadiogram/status/885863588677791746 . It would be tempting to use MFSK64 as our “default” mode, except that there would be enough instances of difficult reception that the number of errors would be unacceptable.

Did anyone experience reception bad enough that only the MFSK16 provided a perfect decode?

This weekend, let’s hope for bad reception – well, at least somewhere – because we will include some Olivia 64-2000 in show. This is a slow mode, only about 25 wpm. And it makes use of the entire 2000 Hz available to us, so you probably don’t want to use an extremely narrow filter. Also, for best results with Olivia 64-2000, turn the squelch (SQL at the bottom right of Fldigi) off.    

Here is the lineup for Shortwave Radiogram, program 4, 15-16 July 2017, all in MFSK32 except where noted:
