I am using the J16 OC Control pins to set the output filter on my XPA125B transmitter. I noticed that Thetis V18.104.22.168-HL2 Beta 3 was not setting the pins correctly when receiving below 30M. J16 pin 4 is set (20M/30M in my setup) is active when pins 1, 2, or 3 should be active. I also see this problem on Beta 5. I did not check Beta 4. I did not see it on Beta 1 or 2.
When I initially installed Beta 5, the J16 pin settings worked correctly. At some point the behavior changed to the above behavior.
I am setting the transmit and receive pin settings the same so I don't have any timing problems setting the XPA125B band on transmit. This behavior has caused the band filter setting to be unreliable when transmitting below 30M. I tried changing RF and MOX delays to no effect.
Here are some screen shot of the pin states for 40M. The first is transmitting, the second is receiving.
