[OZAPRS] HF APRS - Radios

[Glen English VK1XX]

Suggestion

isolation transformer only required for a floating sound card ground and 
or poor shielding/grounding. and the transformer in the case of poor 
shielding/grounding must ave an electrostatic shield (which most do not) 
. sound sound cards expect a floating load, and will object to grounding 
the return to chassis. Some do not care.
