Band Plans

  • 3Y0J will always listen up (using split) so it will be useless to call us on our transmission frequency . Please be sure to double check your settings to make sure you are not calling us simplex.

  • Always give your full callsign. Listening is the key so sure we call you before replying. 

  • CW MAX 15 kHz split (operators chose QRG within a certain bandwidth)

  • SSB MAX 30 kHz split (operators chose QRG within a certain bandwidth)

  • Lowest 10 kHz spectrum on regular bands NO TX  to allow regular DX traffic

  • Lowest 5 kHz on WARC band NO TX to allow regular DX traffic

  • We’re aware of US band plans for E/A/G/N/T

  • FT8 40-10m, with focus on 20-10m yagis.

  • We will transmit:

    • 100W on FT8

    • 1500W on CW/SSB (special permit to transmit up to)



Please follow DX Code of Conduct 


































































Station system diagram and Antennas layout

The setup consist of up to 12 stations at peak time where 8 K3s radios will be fixed to human modes SSB/CW and in addtion we will use 4 SunSDR2 DX as FT8 stations. The 4x FT8 radios can be run from one operator position, or the FT8 radios can be run from any other position individually. Hence, we can run SSB/CW simultaneously with FT8 from every operator position in simplified SO2R like mode, or one operator can run several FT8 radios in parallel from his desk.

There will be NO FT8 robots running unattended at Bouvet, all FT8 QSOs will be initiated by a human operator clicking on the deserving callers. We have a pronounced focus on human modes so to achieve the goal of 200.000 QSOs we will minimize the downtime of all radios and run the FT8 radios 24/7, this also to maximize the ATNO. We will use the S.P.E Expert amplifier and we plan bring in total 10 amplifiers and 14 radios with us. Spares and backup has a high priority in all parts in this project, e.g we will bring with us 3 x 160m antennas, 3x80m antennas and so on and have 4xtribanders 20-10m installed.


As an RX antenna system we will use the LZ1AQ RX loop which has been tested and proves to be a good tool for us in case of in-band interference or noise. This ground independent omnidirectional loop will be located roughly 250m away from the camp and each of the 8xK3S radio will have the possibility to share the signal and listen to this loop simultaneously.
