Less Heat, Cleaner Audio, Fewer False Triggers
This update applies to the RF.Guru Analog HotSPOT SVXLink image dated 2025-12-09.
If you are running an older image:
Please upgrade your image first before applying any configuration changes.
If you are already running the latest image:

Rerun:
sudo hotspot-config
This wil install bug fixes and new features!
Important: Several defaults have changed. Start from the new defaults and adjust step by step from there.
RX CTCSS handling updated
RX now only listens to mapped talkgroup CTCSS tones. This significantly reduces CPU usage (and heat) and greatly lowers the chance of false CTCSS detection. Detection is also stricter than before.
Improved TX audio processing
DSP filters have been added on the TX path to improve intelligibility and consistency. Expect cleaner audio with better presence and control, without sounding processed or harsh.
Announcement level adjusted
The announcement gain has been lowered so it is now in line with normal repeater traffic, avoiding sudden loud level jumps.
HotSPOT frequency fix
An issue where the hotspot frequency was not applied correctly has been fixed.
After updating and rerunning sudo hotspot-config, review your configuration carefully. Do not blindly copy old settings back in — the new defaults are intentional and optimized for stability, audio quality, and long-term reliability.
