>>and aerial that work's <<

To  quote  ''BUT he had not attached his outside antenna!! HI''     Good 
stuff  this  vintage  data, not  like this modern  new  fangled Slow Morse 
everyone  keeps  tapping  on about ..... ))

Yes , I think the  holy grail of large arrays  and  low s/n  performance  on 
RX is  reserved for  those  living  in the  middle of nowhere and 
installations that are  surrounded  with  salt water , either permanently 
or  on a  2 times   in 24 hour rolling  cycle  !

After the  gb100mgy and gb4fpr  runs last  week or so , the  600 ft delta 
loop did a very good job on Rx , feeding the  Apollo Rx  via the  Tx tuner 
.....with  very little background noise ,  oddly  the  504 carrier  was 
virtually under the  noise , so it looks like there is a big  null  out to 
the  west .... not the  best place  for  it ...

1 mile in land  at my qth , with a  top loaded 40  ft  vertical , nothing 
but a wall  of  noise , holding the ra1778   S-meter at  60 to 80 dB in usb 
60% deflection, the  skanti R5003 shows  sinpo 4 signal  level in the  same 
configuration , Tx wise , totally  different , 2  or  3  watts  ros-mf-2 
decoding  in the Shetlands  no  problem .and that's in the  day  time  over 
the  Pennines . wonderful..
