Has anyone ever used or set up a system for recording a VHF transmission?
I think you just want to record the audio output of a receiver that is tuned to a VHF Marine Band channel. As mentioned, this is trivial. The most difficult part will be to find a source of the audio output from the receiver which is not affected by the VOLUME control. If you record the speaker output, the level of the signal will vary with the VOLUME control setting. It would be better to locate a fixed-level output or to modify the receiver to have a fixed level audio output to feed the recorder. This would eliminated the influence of the VOLUME control.

It would be rather complicated to capture and store the actual VHF transmission itself.
