Re: [IRCA] KHAC 880 [ Dysfunctional Carrier + USB ]

[Brian Rachford <azswdxing@xxxxxxxxx>]

Les,

It certainly gives a distinctive look on an SDR.  KRVN has a nice
symmetrical waterfall pattern and there will be an extra "bump" on the high
side from KHAC.  As others have indicated, they get out really well
sometimes, wink, wink, nudge, nudge.  I would think you would have a good
shot especially when phasing out WCBS since everybody else between NM and
AL is supposed to be nulled to the east to protect WCBS.  I hope you can
get it.  One never knows if their power dropping lapses will suddenly end.
