Hello friends,

We return to normal schedule this week. The repeat broadcasts were due to a brief vacation. My wife Jinling and and I drove to the Virginia’s Shenandoah Valley. Our first stop was a nice lunch and visit with Fred, who tunes in and reports on just about every Shortwave Radiogram transmission. 

Our next destination was Luray, Virginia. After dinner, we were treated to an excellent thunderstorm, visible and audible from our hotel’s front porch, moving over a ridge. It was so excellent that it knocked out the electric power to the hotel. This was not too much of a problem, because I packed a flashlight. Power was restored later that night.

The next day we visited the famous Luray Caverns. This is a 1.25-mile (2 km) walk with views of amazing cave formations. The presentation inside the privately-owned Luray Caverns is well executed: The lighting matches the natural colors on the stalactites and stalagmites. They resisted the temptation to use multi-colored lighting and music. 

Jinling took this picture as we walked through the caverns ….

Luray Caverns also provided a means to escape the heat of the Shenandoah Valley, because the year-round temperature in the caverns is 54°F (12°C) — although the high humidity inside the caverns makes it feel more like 65°F (18°C). After the visit to Luray Caverns, we were able to escape the heat again by driving to the nearby Shenandoah National Park. It was cooler in the higher altitudes of the Blue Ridge Mountains.

Olivia 64-2000. With no SSTV from Peter John this week on The Mighty KBC, there will be an Olivia 64-2000 «station ID» at 51 minutes into the Eric van Willegen hours. See this KBC schedule for times and frequencies. One of the transmissions is Sunday, July 27, 0151 UTC on 5950 kHz from WRMI Florida and on KBC’s  891 kHz medium wave transmitter (100 watts) in the Netherlands. The University of Twente SDR in the Netherlands provides a good demonstration of the ability of the Olivia 64-2000 to decode even with barely audible signals. Set the mode manually and make sure Fligi’s squelch (SQL) is off.

A video of the previous Shortwave Radiogram (program 344) is provided by Scott in Ontario (Wednesday 1330 UTC). The audio archive is maintained by Mark in the UK. Analysis is provided by Roger in Germany.
