Yes I watched a signal wander about during Tx
, it started out side the red lines , then moved inside
, bumped about a little then failed to de-code
I don't think it was a key/time
problem . more one of stability , Op
requires a good level of stability to decode ,
from memory op32 is +/- 1 Hz in
32mins , but its not directly scalable
...... +/- 5 Hz may be for Op4 ?

Hi Graham
I have found that if I run 24 Watts no body hears me. If I run one Watt
people hear me?? If I boost the 1 Watt rig to 4 Watts same rig people don't
hear me...... dohh! It may be RF into the Opera PIC keyer? I will next time try
screening the PIC keyer. But the thing is my PC decodes everything.... why?? Any
ideas?

Hi all
While you are all testing Graham's theory on optimum band usage could
you report my OP4 transmissions. I am using the stand alone PIC 'JNT
designed Opera keyer switching my all Valve (Tube for our Cousins) TX.
Power now increased to four (4) Watts O/P from the original 1Watt at
the antenna up lead. Antenna up lead abt 40 ft x 128ft long E/W. from
IO91UX.
