The BITX20 discussion group is a community of people with like interests
and experiences. Some are casual users of the equipment, and most are
licensed ham radio operators who have technical talents as evidenced by
their passing the ham radio exams. The uBITX, and BITXxx, before uBITX
were designed for the Ham radio community. Most of the members of this
discussion group are here to discuss mods, operating, and camaraderie.
As of today there are 7871 members of the group, most of which are
satisfied with their uBITX, BITX40, or earlier BITX20 units. BITX units
have evolved over time, usually involving on-line discussions and suggestions.
The people on this group are willing to help with problems, but that requires
working with these helpers. If one just powers up a new uBITX and starts
pushing buttons without understanding what it might do, then problems may
occur. If you look at the block diagram, and then at the schematic, you will
see that the uBITX is not a simple circuit. It is the result of several years of
design, testing, re-design, and more testing by those with experience in
uBITX boards are "factory tested" before they are shipped. It is unlikely
that a defective uBITX board was overlooked and shipped without testing.
The tests performed at HFSignals have been listed earlier on this group.
The tests performed could be listed again but probably would not mean
much unless the owner takes the effort to understand how the radio works.
Now, some "remote guessing" at what might be the problem.
And, please remember that the members of this group who volunteer
their time to help you with your uBITX are not employees of HFSignals
and do not get paid for their time. The BITX phenomena started as
an idea on an aircraft flight between New York and India. It was initially
built by individuals from junkbox parts. Then one ham started offering
bags of parts (no PCB) for building your own BITX transceiver. And,
the rest is history. Group support is rather unique among manufacturing
of technical products, but is not unheard of. It has worked well for the
uBITX and for the group.
Yes, a long email, but it may help to understand the idea of Group support
and of the uBITX itself.
