ABS version 1.2 was released by Sardar late last year.? Detailed info is at:
Cal and I did a group buy of the boards and components near the end of the year, and I produced some additional documentation that you can find here:
This build works well for all 3 functions (battery, speaker, ATU) when you do the adjustments shown in my build notes and FAQs.?? It is a nice addition to QMX+.

Sardar also released a ver. 2.0 this year.? Please see this message post by Sardar, and also all of the messages in that thread:
The ver 2.0 detailed information is in the link in that first message.
Cal and I have also built this ver. 2.0.? It is nicer in form factor, is easier to assemble, and solves some of the issues encountered and worked-around in ver1.2.? But we have encountered some performance issues with the ATU on 6m, and to a lesser extent on 10m and the lower bands, somewhat similar to those we found in ver1.2.? We started testing and trying to evaluate whether the performance is good enough or if there is an easy workaround to improve it, but we have been side-tracked with the many other priorities in our lives for the last few weeks.? We may also do a group buy for this ABS ver 2.0 solution, and have been keeping a list of interested parties.? But it will still take some time, because we want to make sure it will meet people's expectations and be at least as good as ver 1.2 before doing a group buy, but we haven't had a lot of time to spend on it recently.? If anyone else wants to do some pioneering builds and evaluation of ver 2.0, that would be great.
