- rhinoceraptor 7y agoTrue, but there are a ton of cool things you can do just in ISM. And depending on where you are, your local repeater may not be the most welcoming place, especially if you're not the typical middle age white male.
- ac29 7y agoDepends what you're looking to do. ISM bands are limited to 1W transmit power, and the lowest frequency band with more than a few kHz available in the US is the 902-928 band. High frequency and low power combined tend to mean relatively short range. That being said, I work with 900MHz radio for a living (among other bands), and you can get impressive results in the 1-20 mile range with the right technology and infrastructure. A $10 ham license opens up a significant amount of bandwidth, and power up to 1500W.
