[RTTY] RTTY power levels

[DESLOOVERE DIRK]

Dear,

>From the mark V manual   page 17

... the cooling system is designed to handle continuous duty transmission at
200 watts output.   However , for continuous-duty digital modes like rtty,
we recommend limiting your transmissions to 3 min. or less, with at least 3
min receive in between transmissions.

So the mark V has a 200 w output level at 50 % duty cycle as the
specifications tells us.

For 100 % duty cycle the manal (p 17)  advice you to keep the power output
at 100 w or less.
