Amusing... when I lived in WV I didn't listen to WWVA, I listened to the rock-n-roll stations in Huntington. As a married student at MIT, early every morning I drove my wife to work at Honeywell Datamatic and played WWVA in the car... very loud to keep awake :-) ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Spice is like a sports car...

Some? There are probably 10's of thousands of AM stations in the USA. Your country is smaller than many/most of our states, so you don't appreciate the need for "medium wave" to cover large areas. I could listen to WWVA in Boston (~500 air-miles away) quite clearly with low SNR. ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Spice is like a sports car...

Alaska, Texas and California have a larger land area than Finland, as expected. However, I did not expect Montana to be also slightly larger. FM started here in the early 1950's and only a few people relied on AM in the 1960's. In the 1990's medium wave AM was used to send news to Finnish speaking emigrants in Sweden and to the Finnish speaking minority in NE Russia. Since those days, only hobby based low power (0.1 kW) AM transmitters have been used during some selected weekends, mainly to support DX-listeners. To me, it is a surprise that medium wave AM is still actually used for commercial broadcasting.

The total area of the US is 3,537,441 sq. miles, approximately the same area as Europe... 27X the size of Finland. AM radio is a big financial deal in the US, with annual revenues in excess of $2 billion. ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Spice is like a sports car...
