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

What anuver ole in the road :-)

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.
