====== 60m ======

** A return to 60m in earnest **

I've been active on 60m since it was first available (with a NOV) - and mostly in Digimodes on **FK / 5366.5kHz**, along with a bit of CW and very little SSB. For many years 60m digimodes was the //only// activity I did on the radio. In recent years I've been largely QRT, or having the odd spell on CW, but I still have an interest in 60m as a place for experimentation and for inter-UK communications. 2024 will be my year of 60m, with more SSB operating.

===== Band Utilization =====

  * Captured well by G3NRW's chart {{ :public:radio:uk_60m_5_mhz_band_utilization_chart_band_plan_by_g3nrw.pdf |}}
  * Since this chart was first produced **many more European countries have access to 60m** - mostly using the **WARC** allocation **5351.5 -> 5366.5**
  * The UK was first to have access to 60m but we are now out of touch with how the band is developing, locked in our unique set of //bandlets//.
  * Digimodes among UK stations still takes place on 5366.5kHz (USB Dial) which is an RF centre frequency of 5368.0. This is therefore **out of the WARC allocation**.
    * Many Eu hams choose to ignore this - the WARC allocation goes to //5366.5kHz// and if they set their radios to //5366.5kHz// they operate there ignoring the fact that their actual signal is out of band. 
    * I tend to just work them and leave them to juggle the legalities.
  * I still see the band as interesting mainly for it's use as quiet, mostly channelized band for inter-UK experiments, rather than a band for "working DX".
  * The WARC band has evolved its own internal band-plan.

==== Canada ====

  * Same channels as USA
  * **Also WARC Band 5351.5 -> 5366.5** at 100W ERP 
===== UK : Occupancy versus Bandlet/channel =====

  * I plan to investigate which bandlets are used for amateur QSOs and where/when any non-ham, commercial, military and UNID activity blocks access to our allocated spectrum.
    * Which bandlets are clobbered regularly?
    * Which bandlets have clear SSB channels most of the time?
    * Where are the regular amateur nets, QSOs, CQ calls?

===== Further Information =====


==== Exercise Blue Ham 2024 ====

  * 60m is shared in the UK with the Primary User - military - and we are allowed to have 2-way communication with Cadet Stations.
  * While they do appear occasionally on our shared //bandlets// they tend to be more active on their own specific cadet frequencies
  * Once or twice a year there is a better opportunity to work Cadet Stations - Exercise Blue Ham

=== The next Blue Ham is ===

  * June 17 - June 21 2024
  * All 5MHz UK SSB slots and data on 5366.5
  * See Alpha Charlie [[https://alphacharlie.org.uk/exercise-blue-ham/]]
  * See M0PLT [[https://www.m0plt.me.uk/blueham.php]]
  * Callsigns:
    * Air Cadets : MRxyy
    * Sea Cadets : MFxyy
    * Army Cadets : (tbc)
    * CCF : (tbc)
