Kees, the Kenwood TH-D72A does SO-50; very well. I know it is expensive, but you get what you pay for. It will also send and receive packets to and from the birds, which I am learning to do. You have a great signal on the birds. If you ever get a D72, I will help you set it up and learn to operate it. I love mine. Brad Smith KC9UQR Sent from Brad’s iPad

AO-92 in Camera Mode
by Chris Thompson 11 Jul '19

11 Jul '19

For anyone decoding images and using FoxTelem with Doppler Tracking enabled I would appreciate any feedback on how high speed data is being decoded. Especially if you decoded camera frames in previous runs, like last October, and can compare. This was a new feature and previously tracking of the high speed signal was not great. Let me know if it is better (or worse!) 73 Chris -- Chris E. Thompson chrisethompson(a)gmail.com g0kla(a)arrl.net

Radio Case
by Corlissbs 10 Jul '19

10 Jul '19

Harbor Freight has several cases that are Pelican “knock-offs” and cost 1/3 the cost. I bought two and the quality is as good as Pelican. In fact, the “pluck and pull” foam is actually better than Pelican’s. (I have several Pelican cases) I buy a case for every radio. It is good protection. Brad KC9UQR Sent from Brad’s iPad

Re: [amsat-bb] RF noise from a passing-by BMW i3
by Daniel Schultz 10 Jul '19

10 Jul '19

So BMW can't build a car that meets EMI specs so they just turn off the AM reception and hope that nobody notices? Are there no EMI regulations in Germany? Or maybe its the same mindset that allowed Volkswagen to cheat on their smog emissions by using engine software to trick the inspectors. If they can successfully claim that AM radio is obsolete, others might claim that Amateur Radio is obsolete when we try to complain about interference to our service. Or maybe the cell providers would like to force everyone to stream their news online so that we pay for our data service. The reason that US cars don't have "HD Radio" installed is that the satellite radio providers signed agreements with automakers to put satellite receivers in cars and they don't want to install a free service that might take customers away from subscription based satellite radio services. That plus the fact that "HD Radio" in the USA is a proprietary system that requires payment of licensing fees to iBiquity Inc, unlike Europe's open source digital radio standard. If we don't demand that technology providers observe some level of social reponsibility they will likely argue that the benefits of their new technology will outweigh the loss of "obsolete technology" and the public might accept that argument instead of asking them to spend a little more money to clean up their pollution.

Re: [amsat-bb] Neil Armstrong - Radio ham?
by Daniel Schultz 10 Jul '19

10 Jul '19

I think if Neil Armstrong had been a ham we would have heard about it long ago. He also has not lived in the family house in Wapakoneta since he was a boy, so any antennas must belong to a subsequent owner. Many houses in the rural parts of Ohio have fairly tall towers with television antennas for TV reception far from the cities. Residents of Wapakoneta might be far enough from the TV transmitters to benefit from such a tower. 73, Dan N8FGV ------Original Message------ >I cannot see any mention of Neil Armstrong being a radio ham so does anybody >know if the current owner of the house is a radio ham or perhaps this is just a >random house that happens to have a mast and antennas? >Best 73 Pete G0ABI
