Discriminator Tap

• Rich Carlson's post, with pictures, discussing his tapped PSR-500

• There is also a built in data dump which can be enabled with "CCDump" in the Func-Global "super expert" menu which may meet many users needs when used with 3rd party software which already supports this data. When CCDump = "Yes" most control channel and weather SAME data is dumped to the PC/IF port for use with the USB cable. This may save soldering and warranty issues for most users.
