Did suggest using the same dial for opera and wspr , it was the
same on 500 , opera was off set from 1500 hz to allow this , but is now
1500 Hz all bands , but the boys down under reckoned it was noisy
at that part of the band , so its ended up plonked mid band ,
don't see anything changing till the US is issued with 477 ,
unlikely the fcc would drop a beacon in the middle of the band ...
funny would be if it was allocated the same position as HF bands ..
those long 120 second grinds , would go down very well with the CW by
ear groups ... not
pity on the 2.8k , if it was 3K , then the bfo , mid band would of
given 1.5K each way ... ah , wspr would be inverted , no use then ,
sdr should be able to cope
qrp beacon and Andy ? , it was mid Uk may be north London , Pete
might now , it made psk , which at the time, was the eee's and bee's
of data , Andy did have a cw/psk beacon and ran the 5 meg beacon,
that Gary monitored, using the g3plx system .... I think it reached
ku4xr , he had a plot with a definite lift on the time slot
appy days .. G

Few mill's of wobbly bob all round for that !
We nearly came up you way last week is wobbly bob current or nostalgic?
I think that is my first decode of your mini-beacon ? .. ever !
I don't know if I would have a record on my blog but I think you did RX my
original very similar power TX. I coded Opera on a PIC to key that and I
am sure you RX'd it. I have Op coded with 1/3 missing data in various
ways, that was on 500K of course.
who had the qrss + psk31 beacon with a short Ae , back on 500 K
?. got one view of the
qrss call from that .
Was that JNT ? although he has a fair size antenna.
The new U3 implementation allows for mixed mode beacons , G0MJI
has been running on on MF this week , as well as band stepping
on HF ........ waiting for the up grade to be released
Well erm, yes you have Rx'd another beta ver.
2 mode rx Problem is the separation , but I think the sdr from
Israel has dual watch facility , which would help ... what is
the carrier separation , if it was 3KHz , then 6 KHz b/w and
bfo set to mid , would recover [ opera works usb/lsb] the 2
modes ..
Separation of dial freq is 2.8KHz. You could put one at the top of window
and one at the bottom. Best and fairest way, and I will twist Colin's arm
for a test period and let you know too, would be to put them both on the
same frequency, then I can resonate the antenna on the freq. instead of
guessing on a mid point.
