I have been working directly with Shige on this matter.? Shige did get DXLab Commander installed and working directly with his PW1.? However, the absence of CIV collisions is not consistent and most time fails to work properly after shut down and a restart.? Shige has performed exhaustive tests isolating various components and re-trying shut down and start up.? But the intermittent PW1 CIV collisions persist.?
?
I believe the DXLab Commander PW1 CIV fix is working properly and there is a hardware intermittent somewhere we have been unable to detect.
Shige is going to try a different hardware solution that I am sending him.
+ If the PW1 is connected to Commander's Secondary CAT port and no other device, then the only way CI-V collisions can occur is if the PW1 transmit CI-V messages. Larry K8UT's "riding the CI-V bus" document describes the conditions under which it will do that. See section 4 in
