[Lowfer] DK7FC in EN90xn

[Michael Sapp]

Hi All: Strange growling sounds on audio around 136.172, one could use it for special effects on an old twilight zone or star trek episode....

DK7FC not real pretty like W1VD's copy, but definitely "in there".

First view on my FT-817 with TCXO and 500Hz Collins filter, Acer One PC with newer ARGO version
