Just google search ‘ John Batchelor ‘. His web site is the first result.
Once you are on his web page there are links to four different
radio stations that stream his show live. Stations include WABC in NYC, WBNW in Boston, WMAL in DC and WPRO in Rhode Island.
That is how I have been listening to him for years. I’d hate to miss his show!
He also has a very active Twitter account.
I was on his show on 12/7/17 talking about the 60th anniversary of Vanguard TV-3 and my book GPS Declassified. It was a great experience.
