Hi Graham

My Meter doesn't show that much deviation allowing for the meter dithering less than one Hz. But will look carefully again thanks for info

AH 

 

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.
