Well ..

False  opera  data  decode  =  random  letters  in call  sign  format
False dynamic detection = real call from list with random time stamp
With 2 spots the system will valuate the detection , if web
linked ..
XXX Where there is a remote or QRP TX station , its recommended
that a local off air decode is provide , to inject a time stamp XXX
Luis has this and it validated my detection of his qrp beacon ( for
me it was the second time , as I had detected his beacon while
testing the dynamic mode )

Hi Graham, LF,

I Do have a very low number of false decodes, and when, than all the time
Fantasy call signs. And because it happened in the magic hour I keep
Scratching my head....

I will send him an email asking wether his tx was active or not.

VK3ELV TX beacon is in the psk-map data base Without a second decode / time stamp the system cannot validate it Its definitely in the happy hour window Q Do you have a high number of false dynamic spots ?
if yes,  then  no,  if no,  then may be  yes  ?
