Last weekend's item about the Radio Quiet Zone near Green Bank, West Virginia, included this: "It becomes apparent in Green Bank that visitors have to navigate the old-fashioned way: by reading road signs. That's because GPS comes to a screeching halt as you approach this West Virginia town, which has two churches, an elementary school, a library and the world's largest radio telescope."
VOA Radiogram listener Warren in Arizona took issue with this, pointing out that "GPS units do not transmit."
I've never owned a GPS device. And I will never have a car navigation system because it's difficult enough for me to drive without having to look at stuff on the dashboard. And that's why, when I buy a car (which is not very often), I buy one of the lower-end models that does not have a lot of stuff on the dashboard.
Anyway, it's true that GPS satellite signals can be received, and location determined, even in the Green Bank Radio Quiet Zone. But, to the best of my limited understanding, some car navigation systems also involve maps that are downloaded through cell telephone networks, which are unavailable near the Green Bank telescope.
On to other matters: Last Saturday at about 1625 UTC, the transmitter on 17580 kHz abruptly left the air, leaving many of us with half a picture of the Sputnik satellite. And because the transmitter did not come back, the International Geophysical Year logo (seen above from the Sunday 1930 UTC show) was not seen at all. Let's hope I don't break the transmitter again this weekend.
