Tuning AM Radio

Post by krustillian »



My favourite radio station happens to be on the AM band. Problem is I can't tune into it (or any others) as the AM frequency only progresses 10k/c e.g. 1410, 1420, 1430. I want 1233 and can only get 1230 or 1240. Is this a known problem with the AM tuner? FM works fine.

AM radio frequencies in the US have a 10 KHz spread unlike EU and AUS where they are spread at 9KHz. Evidently the bike is a US Import. Some radios have a selector for both 9 and 10 KHz, I don't know if this is true for the GL1500 radio. Same scenario for FM, 150KHz spread in EU, thus half of the FM channels land on "even" 10ths MHz (e.g. 98.2, 103.4 etc) where in the US the spread is 200KHz and all FM channels land on "odd" 10ths only (e.g. 98.3, 101.7 etc).

Sierra Electronics is very knowledgeable about the GL1500 radios and may be able to advise on this, there may be a selector internal to the radio or on the chassis under the shelter. A friendly call to their repair line or an e-mail and they may be able to help / advise.

If the bike radio can't be switched to EU spec, another option is to get a small portable radio and feed it to the bike stereo thru a cassette adapter or aux input. I got a little AM/FM radio about the size of a hockey puck from a local big-box store for $15....

Thank you for that, all explained. Yes, my bike is a US model imported in late 90s. While riding I usually listen to MP3 running through a cassette adapter. It's a collection of Billboard hits from 60s and 70s. I can live without the AM station.
