ok so i passed my general a few months ago and ive been trying to figure out the 40m band but honestly the band plan stuff is confusing me more than the license exam ever did. like i know there are certain segments for phone and cw but i keep seeing people say stuff like 'stay away from the band edges' and i dont really understand why that matters or how close is too close. i was calling CQ around 7.290 the other night and someone came on and told me i was 'too close to the edge' but 7.300 is where the band ends right so i thought i was fine? also what even is the difference between the band plan and the actual FCC allocations because it seems like two different things that people keep mixing together

yeah this trips up a lot of new generals honestly. so the FCC part 97 allocation is the legal line — for general class on 40m phone youre allowed from 7.225 up to 7.300 MHz. that 7.300 is the hard legal edge, you cant transmit above it. but here is the thing about being 'too close to the edge' — your radio's carrier might be at 7.298 or whatever but your actual voice sidebands extend above that. on USB your signal goes up from the carrier frequency so if you're at 7.299 your audio could easily be splashing into 7.301 or beyond which is out of band. most people say stay at least 3 khz below the top edge to be safe, so like 7.297 at the highest for a voice contact. the guy who told you that wasnt being a jerk, 7.290 is actually fine, maybe he just had a chip on his shoulder or thought you were higher than you were. happens.

the band plan vs allocation thing confused me too when i started. basically allocations are the law, band plans are more like gentlemens agreements the amateur community came up with so everyone isnt stepping on each other. ARRL publishes a band plan that says things like 'hey lets keep digital modes around here and SSB phone over there' but none of thats in part 97, its just tradition and courtesy. so you wont get your license revoked for ignoring the band plan but you will annoy a lot of people lol. the legal stuff is what matters for staying out of trouble, the band plan stuff is for not being that guy on the air
