I think you do see RTTY stations, even in contests, not mobbing the

6 or 7 minutes to make a single QSO is excessive on HF. Reducing the

Erik,
It's call competition. Apparently, you are not aware that DXpeditions
have thousands of stations calling them at the same time. The minimum
power necessary INCLUDES trying to get through the din. The recent
BS7H operators described what they heard in their RX's as a freight
train

combative operating conditions, i.e. in the middle of a contest, or if I

I don't wish to start any wars, just want you to understand some of
the other possible causes of these stronger signals.
Sorry guys, I don't see why any operator should apologize for having a
strong, but clean signal.

It depends upon what your're trying to do.
If you're trying to make a QSO with a station half a world away under
tough propogation conditions, it may indeed be necessary. 1000 watts
may be the minimum power required to make the contact.
Nice idea Andy,

Personally, I'm not really interested in their dog's DNA.
For those modes there is hope of reducing the QSO time. For JT65
there isn't any hope. The agony will always be there.

just what does the edited db value mean? It certainly does not
represent how far the signal is below the RX noise floor.
Since RX gain is unknown, it can't represent some absolute value of
voltage.

Hello brian,
The S/N referenced to a bandwidth is used to compare modes under a

A minimum S/N of 0 dB means that with an equal power
night, I set up MMTTY and it works fine with FSK.
Given a choice between AFSK and FSK, I'd definitely use FSK
for RTTY whenever possible. Maybe it is less important to you.
