Well three of us travelled to Rosmalen in the Netherlands to the Dutch National Radio Fleamarket 2014, this was held on Saturday, the 15th of March 2014. http://www.radiovlooienmarkt.nl/
This event is big and with no main dealers or manufactures present probably only 10% of the items for sale were TX / RX gear. The rest was components and test gear. It is far bigger than Newark and well worth the trip.
We also visited the liberation museum. http://www.bevrijdingsmuseum.nl/basis.aspx?Tid=746
The museum was excellent, our short visit turned into a four hour stay.
