Lightspeed does it again

Stu,

Common problem


With intercoms, not headsets.

: 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).

What's really needed is a separate mic amplifier circuit for each station.
Don't know if the Telex has that. Also, some headsets have a little screw to
adjust mic gain. Careful experimentation with that might help, too.

I don't know of any users of PS Engineering intercoms having ever reported
problems of this kind. The intercom built into the Garmin audio panel takes
perfect care of different headsets, too, in my experience.

The Telex does what you describe. It's the mic's problem, as it
has a very low signal-to-noise ratio... lets in too much ambient noise.

I do have the PS Engineering 1000.
Sure would like to have a quiet ride. My avionics shop cannot find anything
wrong with the radios.

You keep buying from them.

Coleman did that to me 25 years ago. My brother broke the latch on my
ice chest, so I called to order a replacement. When I asked how much,
they answered "Nothing. We don't make things that break." I own a
lot of Coleman stuff now.

Contact PS Engineering, Hank. In my experience, they are uncommonly helpful
with these kinds of things. (I worked with them for a while to "fix" the
automatic squelch that wasn't working quite right. Although the ultimate
solution was a new headset, they were very patient and customer service
oriented.)

Hankal,

not sure what your problem is (not sure if you described it here), but
have you contacted PSE?

NO I have not since my avionics shop tells everything is fine. Maybe they think
it is in the radios.
You haapen to have a number for PSE?
