If the "pops" or "bursts" of ALE is the turkey gobble sound, then this is not a minor point of interference. If a person was on a frequency that has been claimed by the ALE enthusiasts as "their" frequency, and a few dozen users are sending the 8psk signal every so often, that would be intolerable from my perspective. But maybe it only me who would find this a poor amateur practice.
