[RFI] Utility coming tomorrow to chase RFI

[Don Kirk]

HI Paul,

Here is a link to a youtube recording of what I hear on 136 MHZ AM using a
small handheld scanner (Radio Shack Pro-94) that has the AM aircraft band
when listening to power line noise (in this example I have a 20 db
attenuator in line with the antenna).

While this is not a ham radio HT, it does provide an example of what I hear
using this particular model of a handheld VHF receiver.
