VKDMR IPSC3 is designed to be easy to use, but the network still depends on disciplined operating. The better the operating standard, the better the network sounds for everyone else.
Use TG 505 for general VK operation. Use specialised groups only when that audience is what you are actually trying to reach.
Pause between overs. Link set-up, announcement audio, and late-joining paths still need room. Fast overs make good systems sound broken.
Use normal speech level, sensible mic gain, and avoid unnecessary background noise. If parrot says it sounds bad, it is probably bad.
Abuse, deliberate disruption, endless kerchunking, or using the network as a noise generator is not acceptable. Operator controls exist and are used when required.
