[OZAPRS] Fw: 40M APRS frequencies

[Gavin Rogers]

Captured a handful of frames last night here in Perth on 40m. I guess it 
works! Also is my first 40m digital RX, so that's nice :)

VK7HSE-4 audio level = 139(11/14)   [NONE]   __||___
Audio input level is too high.  Reduce so most stations are around 50.
