Hi G..,

Yes, its all OK.
Just an idea: It would be nice to have a possibility to set a beacon stop time. When i'm transmitting over night and would like to stop after my sunset... Should be made easy. Maybe a consideration for the next version?
Just my point of view...

Gary, G..,

Did you ever thought that i will download this program? ;-) I did.
Was just transmitting the first sequence 478.875.
Not sure if i did it correctly. Also the optocoupler which keys the PA may need a parallel R. Will see in the evening.

Questions:
How can i disable that nerving key tone if i use the RS232 output instead of a HF TRX? If i want to listen music during transmitting i cannot disable it...
Next, how can i disable the infos about opera stations of other bands?
Why is the frequency range for 630m partly outside the range (i.e. 478.6...479.8) ????

PS: 2 hours in the night is for CW though :-)

Hi Stefan,
 
If you download & install Opera you can click "Frequency" on the top menu bar. This dropdown will show you the USB dial frequency & the decode frequency range for each band.
 
Opera is not intended for random frequency use as the decode frequency range is small. If you do choose another USB dial frequency for a test or similar you will need to notify other users of your non-standard USB dial frequency or no one will know you are transmitting there, very similar to WSPR.

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?

73, Stefan/DK7FC

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.
