I will start a new thread, I found out that I that my WeatherStation which uses the Ambient Weather ObserverIP has a HopeRF chip and looking at my Spectrum Analyzer there are very strong signals throughout the US915 band - perhaps the Heltec ESP32LoRa 32 (V2) is using a SF or a higher power level that is able to penetrate this other RF and the HopeRF (common among failures) is not as robust, but this is speculation at this point. Still researching.
