 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
