I've heard out of band callers from time to time.

E.g., DX on 18160 listening up. Callers all the way up to 18175!

Yeah, I thought I was hearing a lot of out of band callers on 40 SSB, and wanted a sanity check.  As usual, I realized my mistake after hitting send.  The band plan has changed a lot on 40 since I was last really active on phone.

There are audio recorders that will capture your mistake.  A few years ago I got a nasty surprise from one of the FCC monitoring stations.

Your US band plans are rather complicated. And you're confused, HI!

We used to have "Novice segments" until the licensing restructure here several years ago.

Now we only have sub-bands per mode in VK.

I needed a copy of band plans in view when I got back on air again several years ago to remind me.

People still sometimes allow their upper sideband to extend above the band edge.

Ouch.  Sorry you had to find out the hard way, but glad to hear there's still a cop on the beat.

Fortunately, as it turned out the frequency was legit, although I wasn't transmitting.

Hmmm, wrong VFO?  ;D

Well, during the K1N operation while they were transmitting on 7093 KHz and listening around 7180 to 7185 KHz
I heard several U.S. call on the XMT 7093 KHz frequency. I am pretty sure 7000 to 7125 KHz is RTTY & DATA for US.

It amazes me!!

I encountered a bizzarre case of "out of band" a little over a week ago, quite unlike the usual 40m cases.

Was on 12m CW attempting to work JY9FC on CW around 24.891, but I kept hearing what seemed like a distorted SSB signal interfering. Curious, I switched to USB to try and listen to it. I then switched to LSB and tuned down to 24.889 and...a callsign came through very loud and clear.

There was at the same time the JY was on a Z81B station on ~24.935 working split. So I'm guessing that his VFO B was really messed up...Instead of calling up on USB, he was calling down beyond the bottom band edge on LSB.

There are and will always be LIDs.  To keep myself honest I have the band plan taped immediately above my shack desk and refer to it all the time.  Also, we need to truly understand the functions of our radios.  So many hams don't know how to go split because most don't use that functions all the time.  But that's no excuse for poor operating practices.  Someone once told me that once is a mistake and twice is stupidity.  Making the mistake twice puts you in the LID category.

It's been a while since the FCC changed the size of any of the U.S. phone bands but whenever it did in the past, it seemed to take 2-3 years or longer for everyone to catch up. A few months after the FCC had moved the bottom edge of the 75m phone band to 3750 khz (this was SEVERAL years ago), I was talking with a buddy on 3753 khz. I guy broke in and told us we were out of the U.S. band. I assured him we weren't. I further explained the FCC had recently moved the lower edge down. But he insisted the lower edge was 3760, not 3750. A few minutes later, he broke back in and sheepishly admitted that next time he would wear his reading glasses before sitting down with QST. But better yet was an incident two years after the FCC moved the bottom edge of the 40m phone band to 7125. There was a group of USA stations on 7133 khz calling a DX station in a pile-up. Some guy kept screaming, "You guys are out of the band, you guys are out of the band." This pattern continued for a while until someone finally said back, "The FCC moved the band down to 7125 two years ago. Where have you been?" Suddenly, the kilocycle cop went silent. No wonder DX stations find this confusing. It seems to confuse more USA stations than it should.

Of course if these guys really were out of the phone band, he was just as guilty as they were by transmitting there telling them they are out of the band. Guess it takes one to know one

While not strictly anecdotes about calling out of band, these two illustrate the need to keep up with current events, even in amateur radio. Back in 1976, the FCC authorized the Bicentennial ham call sign program where as all USA ham calls began with an A. At the time, I was WB8TOB so I operated the entire year in '76 as AB8TOB. This was a voluntary program. One day I was on 10 meter SSB when a local broke in and asked why I was using my MARS call on the ham bands. I explained it was a Bicentennial call and had been reported about extensively in the ham radio press of the day. I asked if he subscribed to any ham magazines. Yes, he said, CQ and QST. But do you read them, I asked. No, he replied. And this was May 1976 -- 5 months into the Bicentennial.

But even more bizarre was a QSO I had a couple years ago on 10 meters. I called CQ and a fellow answered me and immediately said he was shocked to hear such a strong signal on 10 meters. He owned 3 homes around the country and each was equipped with a ham shack, tower and triband beam. He only worked 20-10 meters, he said. For the past 2-3 years earlier, he had seldom heard any signals on the higher HF bands and assumed it was because ham radio had died. Total lack of interest from the ham community, he said. But recently, he'd was again hearing signals and was confused by all this.

I told him the period he heard nothing was probably the most recent sunspot cycle minimum and a couple years later, the first peak of the current cycle had come along and filled 10 meters with signals.

He did admit he did not subscribe to any ham radio publications and never looked at any ham websites. Duh, if he'd kept up with current events a little more, he could have answered his own questions.
