[Scan-DC] RE: [MilCom] Long Distance VHF Skip

[Larry Van Horn]

119.275 is a nationwide AWOS/ASOS frequency. Skyharbor does not use
119.275 for their ATIS. That is on 127.575. East coast to west would
have to be a triple hop E-skip and in 40 years I have never seen a
triple hop opening (double hops are pretty rare),  so I have my doubts
that is what you heard Ron. You definitely didn't have F layer as we
don't have the spots to support an MUF that high. And non of the other
modes (Aurora, Meteor, etc) would make it to the other side.

But we apparently had an E-skip opening last night at least into 6
meters. I saw several references to it on AM/FM/TV DX, SCAN-L and a
couple of other list. The opening at one poiunt apparently ran from the
NE US in a SW direction into at least eastern Tennessee/Southwest North
Carolina.

>The only Sky Harbor Airport I could find is in Phoenix AZ. 

Actually AirNav has seven airports with the name Sky Harbor:
KPHX  Phoenix, AZ, USA  Phoenix Sky Harbor International Airport   
KDYT  Duluth, MN, USA  Sky Harbor Airport   
S86  Sultan, WA, USA  Sky Harbor Airport   
1MN8  Webster, MN, USA  Sky Harbor Residential Airpark  Private 
92F  Chattanooga, OK, USA  Chattanooga Sky Harbor Airport   
9AK5  Anchorage, AK, USA  Sky Harbor Airport  Private 
9Y5  Eveleth, MN, USA  Sky Harbor Seaplane Base 

I believe what you heard was an airport talking about Sky Harbor Airport
(KDYT) at Duluth, MN.  They have a 119.275 AWOS-3 setup. Still nice skip
Ron but definitely not Phoenix. ;-)

All,

At 1918 EDT, in the middle of some severe summer wx (heavy rain,
electrical, 
etc) for about 30 seconds I was hearing Sky Harbor Airport
controller/ATIS on 
119.275. The skip came in just at the end of a burst of heavy rain and
stopped 
as soon as the rain had passed.  The only Sky Harbor Airport I could
find is 
in Phoenix AZ. 

Perhpas some of the southwest listeners can confirm that this freq is
used at 
Sky Harbor.

Around here 119.275 is the VHF side of Bay Watch Control for Patuxent
River 
NAS.
