Wow... I started reading the FCC proposal[1], and learned of a new Ham Band, the 630 Meter band.[2] Unfortunately, I live near a 138KV power line, so I likely can't use it.
It'll be interesting to see just how much data can be pushed through 2800 Hz of bandwidth in the real world, at long distance.

- sidewndr46 3y agoWhy would your proximity to a power line stop you from using it? Also there is a band below that you can use as well.

- cenazoic 3y agoBecause it’s in the FCC rules: “...Amateur stations will be permitted to commence operations after a 30 day period unless UTC notifies the station that its fixed location is within one kilometer of Power Line Carrier (PLC) systems operating on the same or overlapping frequencies. This notification process will ensure that amateur stations seeking to operate in the above noted bands are located beyond a minimum separation distance from PLC transmission lines, which will help ensure the compatibility and coexistence of amateur and PLC operations, and promote shared use of the bands.”
- sidewndr46 3y agoI've never heard of anyone having a 630m permit denied due to that. I've never heard of anyone having a 630m permit denied, at all. There is some remote region of Alaska with a power restriction. Also, you can still receive all you want.
- sciurus 3y agoI don't think many power lines have a carrier, though https://en.m.wikipedia.org/wiki/Power-line_communication https://en.m.wikipedia.org/wiki/Power-line_communication
