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.

Subject: LF: OPERA Question
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?

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?

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.
