experimental PTT signaling switch… May 21, 2012May 22, 2012 abram this is an experimental circuit i threw together today. i’ve been working on getting a VOX circuit to work with the Yaesu FT-60R (VX-3R, VX-5, etc.) and Soundmodem on the ol’ Gentoo box. it’s working well, but test packets have been a little iffy.
