2018 August

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.
