I just hard wired my ANR headset into my ship's power so that I no
longer have to use a 9v battery as a power source. Now I am getting an
intermittent squeal when I transmit. I never had this problem with the
9v power pack. My ANR is a Headsets Inc. conversion to a David Clark
headset.
Any ideas how to solve this problem. I used the Headset's Inc. power
cord for the installation.



Is there a built-in intercom?

Is there a portable intercom?


No, it has no intercom at all. Only a simple Comm radio and transponder
with mode C.
