I recently read the manual of the MFJ-8621 data radio. It states that it
needs a "DCD equipped TNC-2 style modem" since it outputs unsquelched
signals. I was planning to use a soundmodem, but I wondered if it provides
this Data Carrier Detect.
(Anyway, I couldn't find any DCD lead on the connector schematics fo the
MFJ-8621)
Thanks for your help.
