Summary
PRC-77 HQ and wearable radios with external handsets, HQ-only recorded traffic and an experimental native listener receiver. Fixes the first PTT selecting the wrong preset.
Description
AN/PRC-77 Tactical Radio — 0.1.4-alpha — Unlisted community test
Fixes the first transmission using 48.20 MHz after selecting 48.00 MHz in the radio radial. Native radio registration could leave the second manpack channel cached for long-range PTT; selecting an already-active first channel returned before refreshing that cache. The correction applies only to the local carrier selecting their own PRC77 backpack. It does not alter native authorization, ownership, normal channel cycling or other radios.
The isolated two-client human test passed: first held PTT stayed on 48.00 and speech was heard by the radio-less listener with the transmitting RTO client's playback muted. Native capture and helper-receive logs agree at 48.00. This is a local diagnostic test, not independent-account certification. Actual audio positioned at the HQ speaker, continuous attenuation and console runtime remain unverified.
Preserves HQ-only intermittent supplied real speech recordings, separate traffic volume, server-managed native listener helpers, handset leases and existing base-to-backpack behavior. Backpacks never schedule recorded ambience. No synthetic dialogue, microphone PCM rebroadcasting or global VON permission changes.
Known limitations: helper reception occurs at the listener character, selected-channel monitoring only; helpers may appear in inventory. Original high-memory shutdown incident remains unexplained. Prior bounded lifecycle and normal client-first shutdown checks passed, but vanilla-reproduced engine resource leak warnings persist. Retain logs during community testing.
