[OZAPRS] APRS and Codan 8528

[Larry]

Hi David

I have been using 8528s as my 40m and 30m gateway radios for over 10 years 
now and they are great for the job - no frequency drift and rock solid.  The 
interface is simple - just make a patch lead to use the mic socket for audio 
in and out ( the pinouts are on Ben's oz radio site) remembering to hook a 
loop wire between pins 7 & 5 to ensure that audio out is available without 
the mic inserted (this is usually done internally in the mic itself so you 
have to do it yourself).

I also use an 8528 with a SMT tracker mounted internally in my vehicle to do 
HF APRS 9vk5ly-15) when mobile.    I can give you details of that mod (a 
little more internal surgery requd ( if you wish.

Cheers
