RAF Air Cadet Exercise Blue Ham 2020

7-8 March 2020

The next Exercise will take place during the 7th – 8th March 2020 – Expected Operating Times 08:00 to 17:00 UTC. Some stations may only be on air on one of the days either in the morning or afternoon, these are known as ‘Pop up stations’.

Please note:- If you are operating on 5398.5kHz you MUST change to another available frequency by 14.30hrs UTC on the Sunday as the RSGB GB2RS Weekly News Bulletin will be read out to all Radio Amateurs from 15:00hrs on this frequency. Do not tune up or operate until this station has announced that the frequency is clear for use.

On the dates above the Royal Air Force Air Cadets (RAFAC) will be organising and running a military style National radio exercise named ‘EXERCISE BLUE HAM 20’ other users may be the Army Cadet Force (ACF), Sea Cadet Corps (SSC) or Combined Cadet Force (CCF) and RAFAC Cadets. To make this successful we would like to invite all Full Licenced Amateur Radio Operators to take part and make contact with our ‘Special Edition Callsigns’ during the weekend.

The exercise will take place on the MoD 5MHz (60 Mtr) Shared Band and will be on the section of the band that Amateurs are authorised to use (Check Licences Conditions and Band Plan). PSK31 Data Mode on 5366.5kHz or Olivia Signal 16/500 may be used on the 5368.0kHz frequency exchanging the same QSO information as listed in bold below.

Cadet stations will be operating on each of the days, mainly from 08:00 to 17:00, but could also be outside these times depending on working conditions. Where possible stations will advertise which frequency they are operating on using the ‘live page’ of the Alpha Charlie website (see link below) as the exercise is in progress and amateurs are welcome to check the page and call in on the advertised frequencies. The website will be going live at the start of the exercise and before that time it may be running test software/calls where all data will be simulated.

Cadet stations will call ‘Alpha Charlie’ which is the equivalent of CQ, amateur stations are welcome to reply to these calls. Exercise Callsigns will all be in the range MRE01 up to MRE98 although other MR, MF and MA prefixed callsigns may be taking part.

The information exchange to complete the contact will be

Your Callsign

  • Your Location – Using the 6 Digit Maidenhead locator only
  • Transmitter Power
  • Radio Check / Signal Report
  • Antenna Type
  • Antenna Direction

Your operating location is to be in 6 digit Maidenhead Square format as it makes it easier to log and can be a location near you. Cadet stations will also be using 6 digits, but this may not necessarily be an accurate location of their station. As Cadet stations change frequency during the exercise contacting them again on a different frequency will score as an additional contact, as these frequency changes they will be reported on the exercise website where possible. Maidenhead locators need to be logged carefully and entered correctly on the system so that Amateur callsigns are shown on the A/C Map in their correct location. The contacts will be plotted almost live on the exercise web server by MRE stations.
