[OZAPRS] Fw: 40M APRS frequencies

[Gavin Rogers]

I'd say mine. I'm using the incredibly technical interface of using an audio cable from the headphone jack to the sound card :) 

The antenna is a long wire, although resonant on 40m, I suffer from S7-9 noise on all bands at all times (suburban areas, woo hoo!) , hence my limited HF experience.
