 - note, that there a is **significant frequency drift** on temperature changes for different modules
   - you need to use **external TCXO** if you are planning to use modules for narrow bandwidths less than 125 kHz 
   - or calibrate clients based on server frequency drift report by changing `cfg.LoraFreq`, for example, let client and server run for an 30-60 minutes and if server reports err: -1500, then set client frequency to about 1000 kHz less, e.g. instead of 433.775 set it to 433.774, this will give couple of additional dB
-  - alternatively automatic calibration could be done on server side by enabling automatic frequency correction by setting `cfg.EnableAutoFreqCorrection` to **true**, might be suitable for experiments where only one client is operating
+  - alternatively automatic calibration could be done on server or client side by enabling automatic frequency correction by setting `cfg.EnableAutoFreqCorrection` to **true**, might be suitable for experiments where only one client is operating or if server broadcast messages, so clients can correct their frequency
  - other useful options are
    - `cfg.EnableSignalReport` set to `true` to enable signal report, it will be added as a comment to APRS-IS submitted location
    - `cfg.EnablePersistentAprsConnection` set to `false` to avoid keeping connection open to APRS-IS
