The town lies on the banks of Lake Constance and the show is held in a modern exhibition centre three miles from the centre, next to the airport. The show runs for three days, Friday to Sunday, and attracts thousands of visitors. This year’s event was the first in three years due to the previous two events being cancelled for Covid reasons. We all wondered whether the enthusiasm to meet up again would overcome travel nervousness and recent travel disruptions – here’s what happened. Getting There and Staying There Although there is an airport at Friedrichshafen (FHN) there are currently no direct flights from 1 the UK. I’ve previously flown to Munich and taken a train, flown to Zürich and taken a train to Friedrichshafen Romanshorn then caught a ferry across the lake to Friedrichshafen or flown to Basel and rented a car. Others fly to Frankfurt and get a connecting flight Ham Radio Show 2022 while a few cross the Channel and drive the 500 mile journey from Calais. I met some from the UK who were adding on additional days to explore the area.

However, I didn’t think you’d be interested in that? Instead, I’m going to regale you all with my al fresco amateur radio misadventures into the big wide fresh-air outdoors. So, I’d better mention the exotic equipment I took with me. An FT-817, an HF whip, a counterpoise, a VHF/UHF antenna of dubious quality and a microphone to stir up some excitement on 20m, or so I hoped. I also brought an old military type Morse key along, just in case a stint on CW might help tempt the weak signals out of the on-air woodwork. Before I get into the action of contacts and that sort of thing, my partner was eager to get away but had other ideas on how we would spend the time away. For a start, she told me she “wanted to breathe in the sea air, sit in a deckchair and watch the waves hit the shoreline and just chill out with a ‘99’ and a G&T”. But that also meant no phone activity (only for emergencies), no excursions or fancy candle-lit dinners. And definitely no “amateur radio racket disturbing the peace”. As you may imagine, it was going to be an uphill struggle to dissuade my other half from her perfect get-away. Anyhow, a couple of bribes later the other half relented. She packed her bag and I packed mine. And of course, I packed my radio gear. Yippee! Some Exotic Hideaway Where did we go, I hear you ask? Sidmouth, on the sunny south Devon coast. When we arrived and parked up the car, we both breathed in at least eight pints of fresh sea bracing air. We waved at the doorman and he happily waved back. We’ve stayed at the same hotel in Sidmouth for yonks, 1 so Paul, the doorman, knew a good thing when he saw it. Another tip was heading his way.
