1060 KYW Philadelphia PA v/s vastasi mukavalla kirjeellä.
It is
my pleasure to confirm your reception of KYW, November 22, 2012 at 1.05 AM EST,
Lapland, Finland, North Europe. I could very clearly identify KYW’s programming
in your attached audio clip.
In the
last few years KYW has received numerous reports of reception from your area; I
do not remember receiving any reception reports from this area in years prior to
2007 I wonder if it the increased use of the SDRs.
Given
that KYW’s directional antenna suppresses the signal in your direction you are
quite lucky to have captured our signal.
KYW broadcasts a news format 24
hours per day, “all news all the time”, essentially the station delivers a
concise synopsis of the news, traffic, sports, entertainment, business and
weather within a 20 minute period of time.
The KYW Radio transmitter is
located in Whitemarsh, PA, a suburb of Philadelphia. The KYW Newsradio studios
are located in downtown Philadelphia, across from the new Constitution Center on
Independence Mall and the historic Liberty Bell.
KYW operates with 50 KW of power 24
hours a day in the hybrid HD digital radio mode and employs a two tower
directional antenna to minimize its signal to the Northeast and the Southwest.
Attached is a picture of our
transmitter building. It was built in 1934 to look like a stone house which is
in keeping with the ambiance of the neighborhood. The two towers are shown to
the right. Inside the building are two Harris DX transmitters, the antenna and
phasing equipment (to generate the directional antenna pattern), HD Radio
generators, audio processors, remote and monitoring equipment and a generator
capable of operating the station for extended periods of
time.
I have an interest in software
defined receivers and was involved with an early development of the commercial
AM /FM /HD software defined radios that are now used in approximately 15 million
HD radio receivers. Many of my Ham
radio friends are using software defined radios and attend I attend some of the
seminars on these radios at the Dayton Hamfest each May.
Thanks,
Glynn
