While comparing my E100 to my 7600GR and E10 -- all of which have 1
kHz tuning steps -- I hear hets near 640 kHz only on the E100, not on
the other two radios. So these hets are internally generated noises
In the last day they've occurred on 637-639 kHz or 638-640 kHz, and
are strongest on the middle frequency (i.e., 638 or 639 kHz).
Does anybody else notice birdies near 640 kHz on their E100 units?
