Ok Alan

Well  these  little  box's seem to  be  on the  increase  , a little  more 
googling  shows  some   intended   development in the   LF and  VHF  bands, 
the  price  is  tempting  , slightly  more tempting  than the  other 
devices on the  market  .. but  from  what I can 'see , the  insides  are 
very  much the  same  and all  have  these   octave  band  filtrs  , but 
notably the  new  improved  PA  web-sdr  was  showing   all  from   5  khz > 
20 MHz ..

useful   would  be the  exciter  version . as together  that  would  replace 
about   1 cubic  yard of   radio-history in the  shack  .. the  cubic   foot 
of  psu's and  power  amp's  may  be around a little  longer  hi

Tnx -G..
