confused about where exactly i can operate on 40m as a general

ok so i passed my general a few weeks ago and im still trying to figure out the frequency thing. i know there are portions of each band i can use but i keep seeing different things online about where to actually operate. like on 40 meters i see people talking about 7.125 and then i also see stuff about staying away from 7.200 area and band edges and honestly its all a bit confusing to me.

my question is basically — is the band plan the same as what the FCC says i can use, or is it like a separate thing that hams just agree on? and what does band edge even mean, why do people make such a big deal about it. i dont want to accidentally transmit somewhere i shouldnt be

good question and honestly it trips up a lot of new generals. so the short version is there are two different things going on. the FCC part title 97 is the actual legal allocation — thats what you HAVE to follow, you can get in trouble if you dont. then theres the band plan which is more like a gentlemans agreement between operators, like where phone goes, where digital modes are, where CW tends to hang out. the band plan isnt law but you'll get a lot of grief if you ignore it.

for 40m as a general you can do phone starting at 7.175 up to 7.300 if i remember right, and CW/digital down lower. the band edge thing is because your radio isnt always perfectly on frequency and if youre running SSB your signal is actually a few kHz wide, so if you park right on 7.175 your lower sideband might bleed into the CW portion. most folks say give yourself at least 3 kHz from the edge just to be safe. 7.200 area gets crazy especially at night because of interference from other parts of the world so a lot of people just avoid it anyway

yeah what he said. also just download the ARRL band plan pdf, it lays it all out visually and its way easier than reading the FCC rules. i spent like an hour confused the same way you are and then someone told me about that chart and it clicked pretty fast. the band edges thing burned me once early on, i was calling CQ on what i thought was a clear frequency and someone came back to tell me i was splashing into the extra portion. embarasing but thats how you learn i guess
