[OZAPRS] Tiny trak 4 help please

[vk2hlt at netspace.net.au]

Guys I cant stress enough how critical the rx audio level adjustment is ! if it
is too low or too high it will never work ( decode ), I just had a play with
mine and for me it seems high 30 to mid 40 seems to be the ideal level of rx
audio to decode nicely, it is a very simple job to adjust as the manual
explains, type "monitor", while the radio is recieving packets watch the level
it will fluctuate from 1 while there is no traffic to whatever it peaks at with
packet traffic, try your peaks at 50 odd and go up or down from there with trial
and error, The problems you guys have been having was my exact problem, which I
fixed by doing the above.
