I am considering trying the Winter Field Day this year.  Not sure what the temp will be on January 24th but odds are it won't be above zero here in Northern Minnesota.  Not sure how to send a report with a minus number.

tnx   ray

Very good question. It's one of those
strange six-element Morse characters.
Is minus prosign DU, BA, or NV?
I always sent "minus" or "below" before
I got the Winkeyer,
but it's good to know the right character
to send for the minus symbol.
The easiest way to do it is,
get the Winkeyer USB and type the character
in the PC keyboard and let the computer figure
out how to send it. The hard part is to copy
those funny characters that sound like a keying
mistake!

Period .-.-.-
Comma --..--
Colon ---...
Question Mark ..--..
Apostrophe or Single Quotation Mark .----.
Hyphen or Minus Sign -....-
Fraction Bar or Slash -..-.
Parentheses -.--.-
Double Quotation Mark .-..-.

You might have to explain to the guy on the other
end that you just sent a minus sign before the temperature.

WQ3T -

The parentheses used to be the same (-.--.-) for both the right and left.  That changed, probably back in the '60s, I think.  Now it's

Left-hand paren:  -.--.
Right-hand paren: -.--.-

As a Navy radioman I used to have to send certain messages of a "personal" nature, starting somewhere around three or four days after the ship arrived in some exotic foreign port...VD contact reports.

These were formatted using semicolons, which was one of the very few punctuation marks we didn't learn in "A" school.  I'd done some research, though, and found that the semicolon is: -.-.-. (a backwards period).  Invariably, the operator on the other end would interrupt, asking what I'd said.  ZWC (operator-to-operator messages) were frowned upon, but that's what we had to use to clarify things.

Just use an 'm'.

If it's -5; send 'm5'.

Report your temperatures in degrees Kelvin -- all the temperature values are positive unless you are reporting about some unusual quantum states that have shown negative Kelvin temperatures.

Thank you for the good information.  I'm going to opt for the "m" if it appears to be an excepted practice during this contest.  The only way to tell is listen first of course which is manditory for any good operating practice.

tnx,   ray

I use "M" and if the other station doesn't get it, I use "NEG," as in "neg 5" to indicate -5.

Almost everybody gets that.

Steve, WIK --

How often do you get "M" temperatures in So. Cal?
