Now that I'm starting to carry passengers in my non-electrical equipped Cygnet, I need a good intercom. Currently, I use a push to talk switch with my handheld I-COM radio, antenna mounted on the windscreen. I use a David Clark headset and everything works great. Now, I need to go to some type of battery powered voice activated intercom that I can also talk/listen to my radio on. I would be interested in hearing what others have done and what you believe is my best option.

Thank,

Jerry Folkerts

Now that I'm starting to carry passengers in my non-electrical 

equipped Cygnet, I need a good intercom. Currently, I use a push to 

talk switch with my handheld I-COM radio, antenna mounted on the 

windscreen. I use a David Clark headset and everything works great. 

Now, I need to go to some type of battery powered voice activated 

intercom that I can also talk/listen to my radio on. I would be 

interested in hearing what others have done and what you believe is 

my best option.

   There are dozens of perfectly adequate intercoms

   with variable noise squelch adjustments. The CRITICAL

   quality for intercom performance is the noise-cancelling

   ability of your microphones. The WORSE they are, the

   tighter the squelch setting and POORER signal to

   noise ratio when you talk.



   David Clark has been a kind of benchmark for

   headset performance . . . but there are some

   really low priced products that work well too.

   Telex Echelons used to be a brand that I fitted

   into our J3 at 1K1 . . . and have two pairs

   in my flight bag. I think I gave about $125

   a pair for them . . . in 1990 . . . but they

   were about half the price of David Clarks.



   There are some excellent buys in portable

   intercoms on eBay . . . here's just one

   the short path to satisfactory intercom

   performance is to us the SAME model headset

   for both slots . . . You'll want similar

   if not identical microphones to maximize

   probability of success. Mix-match headsets

   are not automatically problematic but it

   does add another variable that may tax

   your $time$.
