[Milsurplus] ADF today

[Mark K3MSB]

NDBs are being phased out in the both US and Canada.

Canadian decommissioning will be done in 15 phases over about seven
years.   Phase 4 is due to complete on September 10 of this year:

Due a search on NavCanada NDB decommissioning and you'll find documents
such as:

Similarly,  AOPA offers excellent about US plans for NDB Decommissioning.

On Christmas Eve last year I fired up my RBA for the first time and logged
over 50 NDBs over the next two nights.   Over the winter I used my RBA,
BC-453 (69 stations in one weekend)  and IC-756 Pro III to log over 200
NDBs.    I did more NDB listening than making two way radio contacts and
had a blast.
