Went down the I-5 corridor from near Bellingham down to Seattle Thursday for the Seahawks game. I am still recovering from THAT one!
At the current power level of KWDB I observed the following:
1) You could not listen to the new station really at any point on the freeway.
2) It pretty well wiped out CFMI from Bow Hill to all points south. I would occaisonally get HD lock on Rock 101, but only for a few seconds. When I turned off the HD, it was pretty much a mish-mash of both stations from the Skagit Valley to Smokey Point, where KKXA's translator took over. Prior to the launch of the new signal, CFMI came in clear in HD pretty much all the way to Stanwood.
3) The new signal does not appear to affect KKXA very much at all, which was a plesant surprise. (At least on the interstate- I suspect locatgions facing Puget Sound might be affected to a greater degree.)
Bottom line, this really does appear to be a Whidbey Island signal at this point, which is fine. I understand CFMI has no legal protections in the US, and it shows LOL.
