Re: Code plug Rx and Tx frequencies cracked


 

I call bull. :-)

Since there is no such thing as 'inverted' DPL/DCS/CDCSS/Etc there is no compatibility issue aside from knowing the conversion between inverted vs normal codes.

Motorola probably left it out (if they did) since it is an illusion.

Yes, some receivers use opposite side injection, but that is true even WITHIN manufacturers, and even within the same models. When opposite side injection is used, the bit pattern is inverted and corresponds to a different code.

Again, all you need to know is the conversion.
For those who do not, here it is:

There. I just solved the compatibility problem. :-)

As Dennis and I know DCS compatibility can definitely be an issue!

RSS doesn't seem to have an option for inverting, so you have to do it
by entering the inverse code instead. Therefore I don't think they
expended a bit on it in the code plug. That's interesting since the X
does have a code plug bit for invert.
