The monthly CTARC meeting for May 2018 will be held at the clubhouse on Saturday 26 May 2018, starting at 14h00.

The speaker for this meeting will be Deon Coetzee / ZR1DE, with a talk on the SA AMSAT radio amateur satellite projects and the FunCube SDR.

Deon's enthusiastic involvement in this field over the years is well known and he is an established authority on the subject, and it promises to be a most interesting talk indeed.

Details of forthcoming meetings are usually announced on our Sunday morning CTARC bulletins on the 145.750 MHz repeater, in our newsletter "Ragchew" and on this blogspot.

CTARC Project Loon - 6 May '18

This is an experimental research and development project by formerly Google X. This project is to provide internet access to rural and remote areas. This project uses high-altitude balloons placed in the stratosphere at about 18 Km above sea level.

Two of these balloons have been spotted on an app called "FlightRadar24. (Google it ].

One is about to fly over Cape town in the next few day. As of writing (6 May 2018) at 11h00, balloon Registration N189LB is at an altitude of 57,300 Ft in position Latitude -33.475 and Longitude
13.5493. The track is 104 degrees slightly south of due east. If it continues on it's current track it will pass very close to Cape Town.

It might be possible to bounce VHF or UHF signals off the Mylar balloon material.

There is another balloon which is presently over southern Angola. It's registration is N183LB.

Check out Project Loon on Google and [here and here], and also FlightRadar24 [here].

Hope this is of interest.
