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 type 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. The relay
stays dropped out until I select entry window B, and then
entry window A again.
Any ideas? Thanks in advance.
