SO2R: Antenna may not be changed while transmitting

Tim K9WX · August 2023

Operating the WW Digi contest using WSJT-X paired with N1MM+ and a 6600. When trying to run SO2R, I almost always get a pop-up window from SSDR that says "The antenna may not be changed while transmitting" when switching the TX from one slice to another. And, as a result, there is no TX from the slice that the software is trying to switch to.

The slices are on different intervals, i.e., one is even and one is odd.

Is this caused by a setting I have set incorrectly?

It makes SO2R essentially impossible.

I'm running SSDR 2.9.2 and WSJT-X 2.7.0-rc2

Settings / Radio setup / TX tab, Set the TX Delay to 50ms and get everything working right. Then you can, if you want, decrease it to find where the issues begin and raise it a bit above that level. 35 - 50 will likely cure your issue. The problem is you are sending RF before the switching has time to happen. (It will still pop that up, randomly, throughout the contest and **** TX, it's just part of being a Flex Owner)
