[WriteLog] Strange A/B Relay behavior

Tue Dec 26 20:50:09 EST 2006

I'm trying to get set up for the rtty roundup with so2r 
rtty.
For the first time, I am trying to use the A/B relay for 
some special antenna switching, but when I transmit rtty on 
rig a, the A/B relay drops out. The relay is normally open 
whenever rig b is selected, so there is no problem with rig 
b. It is not an RF problem, because it happens even if I 
disconnect PTT to the two rigs.
I am using DirectIO, and in setup/ports I have only DVK 
(sound card or none) selected for LPT1. The A/B relay 
follows the rig A/rig B entry window just fine. The dropout 
occurs only when sending a rtty message on rig A.
Any ideas? Thanks in advance.
