[50mhz] [VHF] Name this sound

[David Kozinn, K2DBK]

Hi Les,

I'll try to find some time to make a contact, since 6m has certainly been
quiet lately.  I've dropped into pingjockey in the past but haven't really
stuck around long enough to see things happening. I'm definltely a little
pistol station, 100w into a loop, but from what you and others have said it
seems like that should be sufficient.


73,
