Rich, This is my thinking also. I do not think this kind of communications has a place in the ham bands.

In other words, it moves from one frequency to another. The frequency could be in a given amateur radio band or hop to another band. The only other kind of frequency hopping I am familiar with is for a particular spread spectrum technique but that would be a separate issue since as far as I know, FHSS is not used in this application although it may use some kind of SS technique. You also use the term band scanning, but I question if that is the correct terminology since you are scanning a specific frequency within a given band and then typically moving to another band to scan another frequency. Band scanning to me means that you are scanning a range of frequencies across a given band. In any event, how do you propose to properly address the issue of listening on the frequency before transmitting? A fraction of one second does not seem reasonable to me, and even several seconds would be inadequate in most situations. It is not uncommon to listen a minute (or even more) and call QRL? or ask if the frequency is in use on voice and have someone come back out of the blue! The amateur radio bands are not the same as discrete channels typically used in commercial circuits since they are not owned by any individual or group, nor are there assigned frequencies you can transmit on without first listening. The impression you are giving me with your comments below is that since there are so many hams using this mode, they are just going to do whatever they want to do. I have heard ALE signals a number of times from casual tuning around. I did not recognize what they were until about a year ago. If only a few hams use it, then even if they use poor amateur practices, they may not be too obnoxious. But if you get a lot of people using this mode for in effect calling CQ blindly throughout band areas, I can see some concerns developing.
