I’d read the whole article, there’s something about repeated very short transmissions that must be 10 seconds apart, like an outdoor wireless thermometer, also power and antenna considerations that result in short range.

To paraphrase the article: "Allowed under Part 15 for remote controls as long as transmission stops within 5 seconds of releasing the button." I wonder how that jives with a modbus radio.

From: Jaime Solorza Sent: Wednesday, December 4, 2019 10:31 AM To: AnimalFarm Microwave Users Group Subject: [AFMUG] Iris I/O radios Question for the Borg: We are bidding on a large control project for an oil company in west Texas. Their engineering consulting group is from the Netherlands and are specking the Iris I/O Modbus radio that uses the 433.050 to 434.775 Mhz band. My pea brain tells me that is a licensed band set aside for amateur radio and government usage. Do you concur?
