: Have you ever had a problem with squelch noise when you use two different makes
: of headsets.

: that problem is caused by the intercom, not the headsets. Headset microphones
: vary. A decent intercom should and will take care of that. Mayn people cheap out
: on intercoms - and get what they pay for. Jay mentioned the magic words: "PS
: Engineering".

I would answer that with both yes and no. I had intercom issues
with my old David Clark Isocom that had a single squelch. I found a Telex
ProCom4 that had independent (adjustable!) squelch thresholds for each of
the four places, and when the squelch opened, it only opened the one that
spoke. While this does take care of differing mic sensitivities (I no
longer have to shout in my mic to open the squelch), it doesn't change the
different noise characteristics of different headsets. From the
lightspeed K/XL series I've used, some have adequate noise cancellation,
and others have pretty bad noise cancellation. I'm talking *mic* noise,
not headset noise. With two of my headsets, conversation is great, but
when one of the Lightspeed pipes in, the engine and wind noise coming
through the mic is irritatingly loud. Yet another reason I'm considering
the lightspeed QFR CrossCountry2.... better mic (tried one out).
