Thanks for your input. You have stepped forward to provide powerful support for QRP-Labs. I might point out why I am being so forward with due diligence. I am a retired physicist on the north side of my eightyth decade. I was first licensed in 1957. My mind is clear as ever, but the body is shot. This, if bought, will probably be my last rig, so I want it to be right from the first. In reality, I would prefer the high bands to start with, but that is not there. Also, I have had problems with the early SDR units and a little skittish there. And lastly, I am somewhat worried about being able to build the monster even though that is a large part of my enjoyment. Not mentally but physically. All of the teething problems have helped spark that concern.

Part of the due diligence is to figure how far down the road some the upgrades are. From what you say, the high band version is the only one requiring new hardware.

Your personal support of Hans and QRP-Labs is more that welcome and means a lot to me. I will hang around a while longer hoping Hans himself will chip in.

?
Hans incorporated two major hardware features that require future firmware.? These are SWR measurement and the ability to modulate RF amplitude.? I believe that the first firmware that combines the features of QCX and QDX has required more debugging than expected.? There have also been a couple of significant hardware issues that were resolved.?
Thus, I am sure that Hans will include the expanded features, but (as with all software) it will take longer than he expected.

Also, I am looking forward to building a second unit for high bands but I expect this will be delayed until the problem with some QDX having low power on 10M (Possibly QDX T1 identical to QMX T501) is resolved.? Hans does the QDX low power also happen with the 9V T1 winding.

Finally Hans is very creative in his designs and I believe all in this group admire him.
