Re: Release of version 1.2 of ABS solution for QMX+ (Automatic internal antenna tuner, internal battery and internal speaker with audio amp) #ABS #ATU #PSU #QMXplus


 

Please add me to your second buy list. If there are options, I'd like a full kit. Also do you have a rough idea what the price would be?

Thanks,?

Where can I find info on the QMX+ internal ATU; Battery; Speaker - (etc) - being discussed here?
This was designed by Sardar, AC8L.? The major source of information is on his Github page for this project:
?
A bunch of us did a 'group buy' for this (version 1.2), with parts delivered early this year (Cal ordered the circuit cards and processors, and I did the rest of the components).? We started calling it "ABS" for QMX+.?? A search of this message list for topics with "ABS" in the title will return several threads with lots of info.?

I have been placing important assembly notes and answers to FAQ at
?
A few others have done it on their own from Sardar's instructions.

Cal and I may (or may not) at some point in the relatively near future do another group buy, since many have expressed interest.? The group buy lowers cost a bit since many of the items come in quantities or have quantity discounts.? We are keeping a list in case we decide to do it again.??

We have currently built the ABS v1.2, have tested it and worked around some issues as described in the notes referenced above.? I have enjoyed using it to make many contacts - it is very convenient having the internal battery and speaker and tuner all together in the one box.
