openwebrxplus-plugins
This receiver plugin add a new or replaces the default S-meter with a high-resolution, graphical bar display. It automatically switches between HF and VHF/UHF standards.
Preview
Load
Add this line in your init.js file:
// load remote
Plugins.load('https://0xaf.github.io/openwebrxplus-plugins/receiver/smeter/smeter.js');
// or local
Plugins.load('smeter');
Configuration
You can configure the plugin by setting the parameters in your init.js file (before loading the plugin):
// --- S-METER CONFIGURATION (init.js) ---
// These values must be set BEFORE Plugins.load('smeter')
window.smeter_config_global = {
calibration_offset_hf: 0, // Calibration for HF (<30MHz) in dB
calibration_offset_vhf: 0, // Calibration for VHF/UHF (>30MHz) in dB
hide_original: false, // Set to true to hide the original S-meter
show_text: true // Set to false to hide the text below the S-meter
};
Parameter Explanation
- calibration_offset_hf: Adds this value (in dB) to the measured shortwave signal. Useful for compensating for cable attenuation or gain.
- calibration_offset_vhf: Same for frequencies above 30 MHz.
- hide_original: If set to
true, the standard OpenWebRX S-meter is hidden, and only this plugin is displayed. - show_text: If set to
false, the text display (S-value and dBm) below the bar is hidden.
Note on Accuracy
Marat, the developer of OpenWebRX+, states:
“I strongly doubt that many users will manually calibrate their OWRX+ instances. That is exactly why an S-Meter is not integrated into OWRX+ by default: I simply cannot guarantee that correct values are displayed.”
