There's a HAM radio proposal going on. Licensed HAMs tend to be qualified and enlightened people. We need them HAMs here on EE.SE . If HAM questions require some special policy, let's define it.
While not all ham topics would be a fit for EE.SE, most would be. Spectrum usage, FCC regulations, issues of maximizing signal strength, antenna design and orientation, and atmospheric effects on RF are all either directly EE questions or in the problem set of what a professional EE could deal with in a RF project.
Hams often have a great deal of practical get-it-done knowledge, and it would be good to attract more of them to this site. Anyone that has gone thru the trouble to get a ham license has passed a significant moron filter, so unlike arduinies, hams on the whole would be a beneficial addition to this site.
There are some ham-related issues that would be off topic here, like which receiver or transmitter is better, what various models cost, where to get them, etc. This isn't a ham site, but can serve the electronics side of ham radio well.
No, I'm not a ham.
HAMs are as diverse a group as any; some have some impressive advanced knowledge, others are newbies in electronics. That said, I don't think the EE.SE site should entertain all HAM related questions. Many would be off topic if they pertained to spectrum usage, FCC regulations, or non-design questions about signal strength, antenna orientation, atmospheric effects on HF... I'm not saying HAM interests don't belong here, but there's a lot that isn't strictly EE design.
(Yes, I am a HAM.)
Ham or not to ham is the wrong way to ask, IMO - clearly the answers so far reflect that. I think the content of a ham's message should be judged on the merits of the contents of his or her post - just like any other poster's would be.
RF questions are clearly on topic - consider you can't design anything with a processor running over, what is it now, 100MHz, without FCC considerations (in the US, of course).
On the other hand, if a ham posts about cool radio designs he saw at the XYZ ham fest, that'd be a good candidate for off-topic flagging.
Not a ham, was a ham, not a ham, might be again
