A few shots from the 0800-0830 UTC @SWRadiogram session over WRMI 5850 kHz. First shot shows a little of the Olivia 64-2k transmission.

Captured only 6 of the images sent today, mostly poorly.

QTH: Vancouver.

Ready for the overnight (0800-0830 UTC) @SWRadiogram session over WRMI on 5850 kHz. Receiving here in Vancouver. Running two FLdigi sessions, one in MFSK32m, the other in MFSK64, to catch the two types of encoding.

At 0030-0100 UTC, 5050 kHz from WRMI, I finally found perfect conditions.

Via an SDR in Finland, the MFSK32 was almost completely unsuccessful, but the Olivia 64-2000 decoded 100%!

However "America @250" is a full hour, so it looks like SWRG will be bumped from that hour.

[Shortwave Radiogram @SWRadiogram]

Shortwave Radiogram tonight:

2300-2330 UTC on 9455 kHz from WRMI

Scheduled (ie maybe) ...
0030-0100 UTC on 5050 kHz from WRMI
(following Steve Herman's new America @250)

During the 0230-0300 UTC broadcast, 9265 kHz from WINB Pennsylvania, via an SDR in Quebec, the MFSK32, Olivia 64-2000 and MFSK64 text decoded 100%.

Then interference set in. Only 1 image (deer in consolida) decoded. Would have been a good time to test the Olivia.

For the 0230-0300 UTC show, 9265 kHz from WINB Pennsylvania, I stayed up past my usual bedtime in search of a bad signal to demonstrate the Olivia 64-2000.

But via SDRs in Cyprus, Finland, Brazil, Quebec, Alberta, Idaho and BC, the MFSK32 text was 100% with some upper 90s.

Tune in the Friday night (UTC Saturday) broadcast ... 0230-0300 UTC on 9265 kHz from WINB Pennsylvania.

The Olivia 64-2000 starts at 02:36:18.

If the MFSK32 is not successful, the Olivia might be. Manual mode change probably required.

Results from the Thursday 2330-2400 UTC broadcast, 9265 kHz from WINB Pennsylvania, received via SDRs in 1) South Australia and 2) Alberta.

Conditions were too good to demonstrate the ability of Olivia 64-2000.

[Shortwave Radiogram @SWRadiogram]

Another poor signal, but not bad enough to demonstrate the Olivia 64-2000: Received via SDR in Montana, Thursday 2330-2400 UTC, 9265 kHz from WINB Pennsylvania.

[Shortwave Radiogram @SWRadiogram]

During the 2330-2400 UTC broadcast, 9265 kHz from WINB Pennsylvania, via SDR in Qatar, my voice intro was barely audible and completely unintelligible. The MFSK 32 text had 6 error clusters.

But the Olivia 64-2000 decoded 100%.

And, of course, the MFSK64 was a mess.
