However, very high antennas with high gain have shown 33 centimeters can provide good long-range communications almost equal to systems on lower frequencies such as the 70 centimeter band. The band is also used by industrial, scientific, and medical ISM equipment, as well as low-powered unlicensed devices. Amateur stations must accept harmful interference caused by ISM users  but may receive protection from unlicensed devices.
I haven't seen anything on MHz nodes recently, so I thought I'd start a new thread. It looked pretty good. Noise floor was between and dbm.
If you have been thinking about getting on to Mhz 33cm Ham Bands or are active but want to find out more, this is the page you want to be. I don't claim to be an expert in this area but I will share what I have learned, what I now know, what I use and why I picked what I picked. Hardware is very limited on this band, as are repeaters at this point and I think many are just scared due to lack of info.
It is a neat little radio that is front face programmable, like most amateur radio HTs, but unlike any other mhz radio that I have seen to date, all of which require computer programming and software. Moving on from that little radio, my purpose of this post is to share my views and opinions about why the 1. You could also buy the 70 centimeter version of this radio, which had the same memory channels and features, for the same amount of money.

Amateur radio enthusiasts in the US will be interested in Faradayan open-source digital radio that runs on MHz, which amateur radio enthusiasts may know better as the 33 cm band. The band is currently under-utilized, so go nuts! The hardware design and documentation is online, and so is the firmware. The founders of the project would like you to build out a big network of these devices, possibly meshing them together.
There used to be a time when amateur radio was a fairly static pursuit. There was a lot of fascination to be had with building radios, but what you did with them remained constant year on year. By contrast the radio amateur of today lives in a fast-paced world of ever-evolving digital modes, in which much of the excitement comes in pushing the boundaries of what is possible when a radio is connected to a computer. NPR is intended to bring high bandwidth IP networking to radio amateurs in the 70 cm band, and it does this rather cleverly with a modem that contains a single-chip FSK transceiver intended for use in licence-free ISM band applications.
