Polite usage of the amateur bands require that you check the frequency is in use before making a call so no-one should be jamming anybody. Furthermore, no-one should be using ROS in the CW or beacon sub bands. So what exactly is the purpose of this switch and why should anyone need it?
Perhaps an inkling of what may be going to happen can be drawn from some of the comments relating to the performance of the anti-jam switch, for example:
- "The New ROS/2000 passed the test successfully during the CW Contest last weekend."
- "More test with the New ROS/2000 in other hostile environment. This time during a PSK63 Contest on Sunday."
The development of anti-jam techniques suggest that ROS is being readied to engage in war with users of other modes. When users can't find a clear frequency they will just operate on top of other modes. The principal claimed advantage of the wide ROS mode is that it enables contacts to be made under similar weak signal conditions to JT65A but that it permits keyboard chats to take place rather than the basic exchange of signal reports and locators. So it appears that a vast swathe of spectrum space is going to be made unusable for other modes simply so that people can exchange brag files.
We need strict regulation of digital modes on the amateur bands. The days of gentlemen's agreements are over. There are too many modes competing for limited spectrum space, and too many hams who aren't gentlemen.
