I have a Transoceanic 11 band radio made by Zenith in a carrying case. I purchased it in 1975 and it has not seen much play over the years.

Problem: I can only pick up stations on the FM band. I can not get anything on the remaining 10 bands (not even static). The sound from the FM is beautiful however. The problem was something that happened suddenly and was not a progression over time. Does anyone have a clue as to the problem?
Is there something I can do to repair it myself?

Thanks/Steven

Hi,
I assume you have one of the transistorized units rather than a tubed unit.

If you have any way of testing capacitors, even a simple "Go- NoGo" tester will do.

Chances are that one of the electrolytics have simply failed. It is possible that a Transistor in the IF strip for SW and AM(MW) has failed, but this is not as likely a situation based upon your description.

You could pull each electrolytic and see how each behaves on a regular VTVM, but that gets tedius.

Thank you John, for your advice. I will check into what you have said to fix my radio.

Try this site: http://www.transoceanic.nostalgiaair.org/ It has schematics and manuals to download.

Thanks Kent. It is much appreciated.

Steven,

I don't know if you've solved this problem. I had the
exact same problem with a Royal 7000, and was able to
determine that the the voltage regulator transistor
had blown (it was my own fault. I powered it up under
reversed polarity). If you check the site mentioned
by the other poster you can find the schematic. Locate
which transistor is the voltage regulator and find
a replacement for about $1 (NTE makes it, I don't remember the
number, but if you're interested I can find out). The
transistors are socketed. Replacing the transistor
fixed it right up. Your problem might be something else
altogether, but this is at least a possibility.
Good luck.

Larry

Thanks Larry, I appreciate the advice and will follow it to fix my radio

Hello, I know this is an old post, but I have the same problem. The FM plays great, but there is no sound or static on any of the other bands. I did notice inside there is a switch to go from 115 to 230 and my radio was in the 230 position. I switched to the 115 and still the same problem. The Radio was found at goodwill for $5 in mint condition looks like it never had battires in it. I wonder this was a problem at the factory having it in the wrong voltage range. Has anyone have any anwsers?
Thanks
David

clean the band swicht, maybe fix the problem.
(Deoxit is the best option)

That would be a great idea, I found that the volume and tone control had static in them. They now sound great after cleaning. The band switch is very complex and I guess it had been sitting in the Fm position for years, so the rest of the contacts got gunk on them. I hope this is the problem.
Thanks
David

PROBLEM SOLVED!!!!! IT TURNED OUT TO BE THE MANUAL RF GAIN KNOB WAS IN THE ON POSTION. IT ACTUALY HAS TO CLICK OFF IN THE FAR LEFT POSITION TO ALLOW THE OTHER BANDS TO WORK. WHO WOULD HAVE KNOW?????...LOL
