John, The ubitx is a learning platform and that comes with tradeoffs. One thing you can do is fix the keying by modifying the firmware in the arduino source and reuploading it. Or using the CEC software. If you find the power output is lacking, one easy fix is to replace the PA capacitors with some that have a higher voltage rating than 25v and run the PA on 36 volts. That made a day and night difference for me and has made the ubitx much more enjoyable to operate, but you will need a real heatsink. The thing with the ubitx is that it is not meant to be a commercial product. It is not competing with the likes of the big three. It is meant for you to learn on and to be able to modify into your own radio, built for you. It is meant to be cheap to repair. I don't think that I would try have the things on a big three radio that I am willing to tweak around with on my ubitx. I run digital modes at 36v 1.35A for several minutes at a time. Thats pretty hard on any radio when you run it this hard thermally with the duty cycles I do, and considering the whole thing cost me around $145?to build. Its pretty darn good. Look, the point I am getting at is this is a radio meant to get your hands dirty and teach you lessons that you are not going to learn on any other radio due to people not wanting to harm their more expensive rigs.

I am aware that the uBITX is wildly popular. And the CAT rig control for it came about rather quickly compared to some other great useful hacks. But I have also seen power output charts from at least a few people here on this list indicating 10 watts at lower frequencies and 1 or 2 watts at higher frequencies, and disappointing CW performance with how it responds to keying. CW was one of it's biggest selling points. I feel too much work and money has to be invested into it after the initial cost to make it into something I would like. I would rather save my money and buy something else. That's just how I feel about it. And I feel that a dedicated band transceiver to begin with could have better overall performance, and would be popular with people who don't have or want an all band antenna. And thanks Jerry for not being too harsh with me. This list's reputation as being a hate group on other message boards and pages may need reassessing. I'll put in a good word for you on one of them somewhere. --
