2022 April

Hans flew to Finland in the beginning of August and brought his old pen-size airband receiver. It did not work at all. So before his next flight he decides to get a new airband radio, preferable a scanner.

Instead of going for an all band receiver like Icom R6 he decides to buy a dedicated air band scanner. The EZI33XLT is bought 2018-08-21 from Limmared Radio for 795 SEK.

Serial No: 78000093

Good

  • Small.
  • Few buttons but easy to use.

Bad

  • Perhaps not the fastest scanner.
  • No dial for frequency enter, only up/down-buttons.

Diamond RH795 antenna, August 2018

  • Range: 70–1000 MHz
  • Gain: 2,15 dBi

January 1988

A former coworker to Hans has this Argonaut for sale and Hans buys it for SEK 1600. The unit is known to have a good receiver and is quite small and can run on 12 V for mobile operation.

Hans connects a small antenna, too small, and starts to send CQ CQ. Nobody answers. The rest of the time the transceiver is used for listening only.
