Edited

K3SIW resumed  sending  Opera /  op32 on the  USA LOWfer band ,  previous  best  distances 
KU4XR with multiple decodes 

Previous results have been  quite 'amazing, considering ,LowFER transmitters may not use antennas
longer than 50 feet or final RF stage input powers that exceeds 1 Watt [NB  power looks to  be in the  mW 
as  previous  spots  from  Nk9M + 6 d/b ]

This was a  single  event , G4WGT , monitoring  185 , posted a  single
correlation [deep search]  spot , with  matching  frequency 
and time stamp [ time from RX pc clock]  opera shows 136 band 
would be better to  have a repeat  !
