Panasonic RM1100 Radio-Cassette

Postby lopet » Mon Mar 10, 2014 4:28 am



My Panasonic RM1100 Radio-Cassette is not working very well. The ST (FM Stereo Indicator) vanishes suddenly and occasionally from the LCD display and then I hear nothing. Is there anybody who knows what kind of an error that is? But I do not use the intercom and the cassette player, only the FM Radio. Maybe some one has some experience with replacing it with another kind of radio and how to do it? Which one will fit in?

First thing I would do is check the antenna cable. It could simply be coming loose, have corrosion, etc. Check the antenna itself as well.

Thanks for this good advice. I have had the same suspicion. Therefore I have checked the antenna connections in the radio and at the antenna, but could not find any break or loose connection at those points. And I know there can be millions of other breakpoints or loose connections, but how can I find them? Is there any measuring method one could use? The antenna should be quit all right, because I bought a new one last year. But once again – thanks. It confirms my one thought about the trouble.

Well the easiest thing to do first is to check for continuity. Set up an ohmmeter and measure the antenna mast to the center pin on the antenna connector. It should be 0 ohms or very close to 0 ohms. Do the same for the outer part of the connector and the ground part of the antenna mast (base). This will tell you if you have a bad connector or wire break somewhere in the antenna system.

Check the contacts and connections first, but before I considered a replacement .... what I'ld do is call Sierra Electronics in Troy Ohio and arrange to send the radio insured direct to them for a testing and tune up. They'll clean the deck, replace the drive belt, and fix other problems, likely for less than whet you'll spend making something else fit and even more likely with greater satisfaction.

I sent mine to Sierra last Fall after the riding season and got it back in 10 days and works like new! 125.00 included shipping. As long as the problem is in the radio and not the bike of course...

As an old Radio engeneer i would start to separate the periodic non RF signal problem.
Is it the radio or the bikes connectors, antenna combiners, bad earth connection various Places or a bad antenna rod connection ?

Mount your Radio into a Fellows GW and monitor if the fault follows your radio. Or lent a radio from an Fellow winger. Now after that simple test, you will be able to find were to look - radio or bike.
