ok so i just passed my technician exam like three weeks ago and im still trying to figure out the rules around what frequencies i can actually use. i read through part 97 or at least tried to but honestly its kind of dense and hard to follow if you dont have a background in this stuff.

my main question is about HF — someone at my local club said technicians get some HF privileges but then another guy said it barely matters because its such a narrow slice. and then theres the whole thing about phone vs CW and i got confused. also does the band plan stuff come from the FCC or is that like a separate thing that the ham community just decided on? because i see references to ARRL band plans and i wasnt sure if those are legally binding or just recommendations.

sorry if this is a dumb question im just trying to not accidentally transmit somewhere i shouldnt be

not a dumb question at all, this stuff trips up a lot of new hams. so the short version — technicians do get some HF but yeah its limited. you get 10 meters for phone above 28.300 MHz and there are small CW/data slices on 15, 40, and 80 meters too but they're pretty narrow. the 10 meter phone allocation is actually the most useful of the bunch, especially when the solar cycle is up like it is now.

as for your band plan question, thats actually a really good one that a lot of people dont think to ask. the FCC allocates frequency ranges to different services and sets the license class privileges within amateur radio, but the specific band plans you see on the ARRL website are voluntary gentlemens agreements basically. so technically nobody can fine you for calling CQ on a frequency thats traditionally used for digital modes, but you'll get an earful from other operators. the FCC rules are the legal floor, band plans are the social contract on top of that.

grab a copy of the ARRL handbook or even just the part 97 quick reference card they publish, it lays out the privileges by license class in a table thats way easier to read than the actual regulation text.

yeah i was in the same boat when i got my tech. the HF privileges feel kind of like a teaser honestly, enough to make you want to upgrade haha. i ended up just bookmarking the ARRL frequency chart and checking it constantly for the first few months until it started to stick. one thing that helped me was actually getting on 10 meters when it was open and hearing people work DX, made me want to get my general pretty fast
