[Scan-DC] 225.0 as CLAW preset

[Jeffery R. Smith]

Not sure about the IF Bandwidth. Spacing is at 25K.

Trick to it was the BC780 found the freq through searching. The Pro-2035
with OS535 interface installed was scanning the freq when the audio was
recorded. Comms were loud & clear.

Could very well be 225.025 are possibly even 225.050. I am just a little
surprised the BC780 did not pick up any hits on those freqs as well.

Oh well. Claws should be getting ready to head home soon anyway so I am =
not
going to sweat it.
