There are over 40 Washington, DC radio stations within listening distance to downtown. Most DC-based radio 
transmitter towers are shorter than in most cities, since most are located on shorter buildings or in the suburbs. This causes reception to be poor. It is partially because Washington, DC allows no buildings to be built that are taller than the tip of the statute on the Capitol Building (228 feet), other than the Washington Monument (555 feet).
The tallest radio/TV tower (also the tallest structure) in the District is located at 6001 Georgia Ave., at 9th and Peabody Streets, NW. At 761 feet (232 meters) tall, the tower is a couple hundred feet taller than the Washington Monument, but it doesn’t carry commercial radio signals, only television (The CW - Channel 50), and DC Police radio signals.
Since no broadcast towers in DC even come close to the towers that hit as high as 1,500 feet (500 meters) on top of 100-story skyscrapers in many large cities, radio reception tends to fades in and out as you move around the city and suburbs. Even in hotels, some within a few miles of downtown, solid reception can be impossible.
But if you do want to find a specific station or radio format without searching the dial, check out Radio-Locator, a web site that finds all the local radio stations in a specific geographical area.

But don’t get too attached to the station. In the last year, my favorite classical station changed to Gospel, my jazz station went oldies, my rock station went all shock-idiot talk.
Luckily, many of the station have live feeds, so even if you don’t live within the reception area, you can still get a piece of local flavor over the net.

华盛顿特区的广播电台
在距离华盛顿特区市中心收听距离内，有40多家广播电台。与大多数城市相比，绝大部分的华盛顿电台的信号发射塔都不算高，因为它们不是坐落在不高的大楼里，就是位于郊区。但是这给接受信号带来一定困难。其中一部分原因是华盛顿特区不允许任何大厦建的比国会大厦（228英尺）高，华盛顿纪念碑（555英尺高）除外。
特区内最高的广播电视塔（也是最高的建筑）坐落在乔治亚广场6001号，在第9大街，及皮波迪街西北处。它远比华盛顿纪念碑要高，有761英尺（232米），但是它不收发商业广播信号，仅限于电视信号（像CW电视台到Channel50）和特区警察广播信号。
因为特区的广播电视塔没有一座像其它一些大城市的那样，既有1500英尺的高度（500米），又坐落在100层的摩天大楼里，所以当你往返于市郊之间时，信号会断断续续。即使在离市中心几英里远的酒店里，信号也不够稳定。
如果你想要搜索特定的电台或是广播节目，又不想拨动选台标度盘一个一个找，那么就到一个叫广播电台定位仪的网站，在那里你可以找到所有的想要广播电台。

但是你也不要太迷恋电台。去年，我最喜欢的经典电台经过全心打造成了宗教电台，我喜欢的爵士乐电台不复存在了，我喜欢的摇滚乐电台也变成了愚蠢至极的访谈类节目。
幸好，很多电台都有网络直播的，所以如果你不在广播信号接收区域内，你仍然可以通过网络收听。
