Re: Other Bitx-40 on the air in CO (Cuba)
I am very happy, because one them was checking by AD4C, -a friend- , and
told us the filter has 2.7Khz. It's sound good .
Now I am going to use this group of guys how a reference, because they have
the enough knowledge and skill to help other.
The other project they accomplished very well and easily was the W6JL
linear power amplifier, using the small toroid from the saver light, and
any MOSFET they can get it.
CO6ATL has an special trick to protect the unknown MOSFET during the test.
He use a car battery bulb in serie with the Vcc from the power supply,it's
all is ok the lamp light up very poor, but is something is wrong it's light
They has a big list from the MOSFET tested recovered from old computer
I am helping them to use more and more the microcontroller, at this time
they can reproduce and programing almost the project you can find on the
I have learned how to get the PIC's like sample and the other componentes
useful and important.(16F84A,16LF84A, 16F628A,16LF628A,etc.)
I want to introduce the use of NA602AN, they don' t know and it's very good.
We have the TA serie, but with no specific project
Now, the new goal is the DDS, with the lower cost
I am working hard to do that and i want to find someone in CO to learn
about EAGLE, because the future is to have the GERBER files in all the
