RE: Com port output clattering / PTT control problem


Take a look at this page of the excellent FAQ:

Two sections to look at are:

Interfacing the SCS-PTC IIe

Sound Cards and the FT-847 - Updated 21Mar01

The second section contains the following:  "Some hams have found that they
need to replace the 10 mf capacitor on the schematic with a 0.1 mf capacitor
to avoid relay chattering when releasing from TX in PSK31."

Lots of other good stuff there as well.  Good luck!



Fear not your enemies, for they can only kill you.
Fear not your friends, for they can only betray you.
Fear only the indifferent who permit the killers and
betrayers to walk safely upon the earth.
