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.
here’s a picture of my mobile APRS setup in the Jeep. it’s been a fun project from time to time. eventually, i plan on constructing a 2m vertical antenna to throw on the roof for better satellite reception while being mobile. i’m currently using a high-gain Comet mag-mount which is an excellent antenna. i was actually able to get out over 20 miles the other night on 146.52 with K5YLE using only 5 watts on the FT-60. for satellite reception, i’ll have to do a custom design.
the setup uses the FT-60R packet cable design into my Gentoo Linux laptop (Samsung N210) running soundmodem and Xastir.
