Mapping LoRa Signal Strength

Has anybody reading this thread ever mapped LoRa signals and their strength dBm (decibel milliwatts)? What sort of gadget did you use for measuring the RSSI and SNR?

I've been playing around with Emlid RS2+ units and testing their internal LoRa communications for its base to rover corrections; however, they don't have a radio signal strength indicator or signal to noise indicator. It either has or hasn't received the base's LoRa signal, or maybe it's just in a dicey location and sort of flickers on and off.
