[Boatanchors] trying to identify a signal on 13.450 Mhzvaryingto13.400 Mhz

Thu Oct 8 22:03:50 EDT 2009

You can always get assistance with station identification, be said station 
Ham or Short-Wave, by first subscribing to and then posting a question on 
the SWL list:

swl at mailman.qth.net

A lot of listeners there who delight in crusing the bands with one ear 
afixed to the speaker cabinet, or in some cases the speaker cone itself! The 
'silent' but substance rich variety of radio hobbyist.
