This might only work with Rev 1 of the device Rev 2 - 4 definitely
won't work with that.
Revision 5 uses a completely different demodulator and will only cause
errors with this.
And by far it's no clone of the other device the circuits are totally different.
If you insist on supporting our devices don't load it as default only
people who have the
first rev. with bad sensitivity should use it.
Not accepted because of that.
