19.2Kbps, by replacing one of the 455khz IF bandpass filters. Instructions

Soundblaster Packet modem software developed for linux. See below for more

Antenna Systems
The point-to-point links are using the
Cushcraft
A43011S 11 element Yagi, and for omnidirectional installations, the Cushcraft
ARX450B. Both of these antennas cost less than $100, and were purchased
through Ham Radio Outlet.
Other antenna systems can be hand built.
CQ Magazine, and again in 73 Amateur Radio Magazine have published plans
for inexpensive homebuilt antenna systems.
