Title: What is 72?
Post by: W8JI on October 25, 2012, 09:27:09 AM
OK, I know all about 88, 73, 10-4, 666, and even 69, but what is 72 and why do we need it?

I hear people saying 72 to each other today. Is that "regards" instead of "best regards"?

It's the QRP version of 73. Do more with less.

OK, thanks. I wondered what it was.

At what power level is 72 preferable or acceptable compared to 73? This is common?

It's a QRP thing; apparently begun by RV3GM. So 5 watts or less.

I used to use "72" on phone back in the 60s.

When asked, I'd say, "It's like 73, but I'll owe you one."

There's no rules or power requirements per say it's just a not-so-secret handshake amongst QRP enthusiasts. Not all of them embrace it but many do. I usually respond to it with 73 out of sheer habit.

I have a friend whose father,  now SK, was a ham so she grew up hearing 73 and 88 all the time.  Once, when I emailed her, I finished with "73/88".  She reminded me that I'm happily married, and suggested that the "88" part belongs at home.

So from then on, I've used "44".  She caught right on with that!

And of course 73+88 = 161, which is what members of the First Class CW Operators Club (FOC) send to each other, if you happen to run across that.

I understand they really think extra highly of each other to call each other "first class" compared to the rest of the peons in the hobby, but that seems a little over-affectionate for my crowd.

Sure, Why not concentrate the whole rubber stamp QSO to
K3TN de PA0BLAH 348569 de PA0BLAH
with 348596 the sum of the translation A=1 B=2 ...Z=26

No, when you start at school you are first grade.  So reasonable to think FOC are First grade operators.
The first will be the last and the last will be the first, something written in the bible.

I like Qrp and think 72 is classy and funny .  I did not know what it stood for either but when I did find out hear I put a smile on and had a little chuckle !  nothing wrong with having fun .  John Molenda kb2huk

Yes - that's at least 52 years old.  Comes from one station sending "SK 73 de K7KBN ese."

The "ese" part, of course, sounds like "shave and a haircut".  The other station sends the "ee", representing the "two bits".

But I think I have not heard the "ese" since I was a novice in the 70's. But the "ee" comes after pretty much every QSO (at least for me).

Well, that explains it.  You no longer get a "shave and a haircut", but you still have to pay the "two bits".  It's called "economics" and it gives me a headache.    ;D

I would guess that 75% of my QSOs end with the "shave and a haircut" thing. I often send it and I often have it sent to me. But probably 95% of my QSOs end with the dit dit. Even DX stations.

Does anyone know what the story is on the guy that sends like a little tune in CW on 40 meters ? I have always been doing something over on the workbench when I heard it and didn't give it my full attention. Then afterwards I regret not having payed better attention. I last heard it a week or so ago and I can't even remember the tune. I had the impression that he was ending a QSO. He sends what sounds like a little tune and repeats it several times.
 I have heard it more than once, I don't remember where but some where around 7.040 (I think slightly lower than that). I am thinking it is some kind of net, or club.
It's kind of cool. I think it is in the afternoon maybe around 3:00 EST (around that time of afternoon).

I know the guy that you are talking about.  He sends machine perfect code with a straight key.  Can't remember his call though.  He's sending something like "BENS BEST BENT WIRE"  but there's more to it than that.  He told me once that it was a practice thing.  I've heard him use it many times when the bands are dead and no one is answering.  He'll include the whole ditty in his CQ call.  One of the best fists I've ever copied...

cheers

That might be it. I have been sitting here sending that. It's fun even if that isn't him.

Oh, that is definitely it.
I can't stop sending it now. I am addicted.

Yep, I've heard him on the air frequently in the evenings on 40 here in Oakland CA. Always a nice signal and a wonderful fist. And when I first heard his musical number it really tickled me. Now I know just what it is. "Bens best bent wire" is much more interesting than "CQ" and probably will get you more replies.

Can't appreciate that. May be kind of music but interpreted as Morse code it is really bad.

UU22UU or whatever is one large bunch of dots and dashes without a letter space, so multi interpretable.
There are no word spaces in the text only letter spaces, and _wire_ is not sent because there is no letter space between w and i and hence it is possibly wi but also possible ez or ad or pe

So making music is one thing but doing that kind of entertainment by mutilating Morse code is another  thing, that makes such a kind of fist very hard and tiring to copy.
