I was searching out some information on the SoftRock-40 radio kits
that Steve Ireland VK6VZ mentioned in a post back in January and I
got the following info from Tony Parks and thought you guys might be
interested. He is selling a receiver kit for 160 meters and another
for 40/80 meters at $14 each.
