|Phase 8 ~ Hacking the Bitx40|
One of VU2ESE's goals was that the Bitx40 would be an experimenter's platform when the builder would be encouraged to test drive new add on's or other ancillary circuits.
The first hack that I did was the Arduino +AD9850 DDS VFO but the new add on board gives you the digital VFO capability. This now obviates the need to provide detail on that hack. If you have a burning desire to find out how I did it then send me an email to N6QW
There are two worthwhile hacks that I developed aside from the Arduino driving an AD9850 and those encompass reverse voltage protection and controlling an external linear amplifier.
VU2ESE's web page on http://hfsigs.com has a hacks page and that should be read as well.
