Content preview: Opera experts, I have a simple question to Opera. If the program keys a PTT of a PA like a CW key and the operator can choose the frequency where he transmits, what is the range of frequencies where a decode can be expected from someone who set his RX to e.g. 477 kHz? Is it a USB bandwidth, so maybe from 300...3000 Hz, i.e. 477.3...480 kHz?? Can i completely free decide where i want to transmit on? And if someone decides to let Opera choose the transmit frequency in that band (e.g. by using a HF TRX and a transverter), where does the program usually transmit. Is is accidentially oder is the range much more limited?

I have a simple question to Opera. If the program keys a PTT of a PA like a CW key and the operator can choose the frequency where he transmits, what is the range of frequencies where a decode can be expected from someone who set his RX to e.g. 477 kHz? Is it a USB bandwidth, so maybe from 300...3000 Hz, i.e. 477.3...480 kHz?? Can i completely free decide where i want to transmit on?
And if someone decides to let Opera choose the transmit frequency in that band (e.g. by using a HF TRX and a transverter), where does the program usually transmit. Is is accidentially oder is the range much more limited?

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?

TNX FER RPRT
Am now sending op4 on 500 at 1/2 intervals on the hour and 1/2 hour very approx. Can you report please if available will try to keep it on most of afternoon.

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.
