Re: Possible PA low output problem.


 

The hour is to debug an amp. ?Getting all that going on the Raduino and sorting out complete test procedures for the Bitx40 would take a month or two. ?Designing it is not trivial, but once done it would be very cheap to reproduce. ?All these tools would be available to the experimenter for other projects. ?Could also be a standalone board as you say with Si5351, display, and Nano also, but some of the trivial stuff may as well be on the main board so nobody is sitting on their hands for an extra month.. ?Just an N5ESE type RF probe sitting out on a corner of the board would be very nice. ?There is electronics out in the world designed to be easily self-debugged for most problems, and it's a joy to butt heads with. ?Most projects, commercial or amateur, simply don't put the time into it, and most consumers wouldn't bother to mess with it anyway. ?But on a significantly complex project like this with thousands of copies going out to experimenters, we either put the time into tools, or put way more time into playing wack-a-mole as the various problems come up. ?

Just because you have not heard of this being done does not mean it is unreasonable. ?How would you solve the issue of some new ham with a voltmeter and a Bitx40 that doesn't quite work?

?Well, why not just go ahead and figure it out and post your work to the group? I've never heard of a kit or fully-wired rig come with such rudimentary test facilities before, so what you ask borders on the unreasonable (especially since you've already proposed it before). If "green squirts" will use the BitX40 as a first experience in homebrew experimentation, then they will need some test gear that can be used on other projects, not built into just one. The test functions you propose could readily fit on a small stand-alone pcb, and as you suggest would not take much time for a more experienced Ham--such as yourself--to design and offer, either for sale or as an open-source design.
