I did the 10m test this weekend, and had a dx send me his seriel number as "TTB2". The next call he had was "TTB3". I know what T is and what N is, but what is "B".  I'm new to contesting so this has me puzzled. Tnx - K3MQ

It stands for 7.

There does seem to be some logic to it as.  Here are some of the "cut" numbers.

9 = -.
8 = -..
7 = -...
6 = -....

A caution on using cut numbers...

The only cut numbers I've heard in contests have been E=5, N=9, T=0, A=1.  The other cuts don't save much time and are more likely to just cause confusion.  Even the A & E are not that commonly used.  Some op.'s will send an O (3 dashes) for 0 (5 dashes), but if you're cutting numbers anyway why not just send T?

The 'TTB2' you heard is strange.  The B is technically the cut for 7, but I wonder if thats what he really meant to send.  I sometimes hear B mistakingly sent instead of a 6.  And what about the two preceeding T's?  Why would he feel the need to send 4 digits?  You think that whole thing was just a sloppy 82?

Anyway, the objective during contests should be to convey the exchange as quickly AND efficiently as possible.  Sometimes that means slowing down.

I don't like the "cut" numbers either and never use them but since some do, you need to know them to copy them.

It kind of throws you off at first. After eight hours of listening to them you get the hang of it. I find that EU operators do this the most. I would prefer the whole number to be sure, but what is one to do in the heat of battle?

I agree.  During contests I will only use :

n = -.  for '9'
a = .-  for '1'
t = -   for '0'

after that, I think it leads to confusion.
