    Thanks alot sir, but do you think i can do it with the soldering iron?

  • happyyear Nov 19, 2008

    the problem about diamonds is that they are already locked :( sorry.
    but if you can tell me how to disassemble and their place  in some pics, i would really appreciate that.
    thanks you sir, you are really a pro, and if i have the chance of changing the rating i will do it.

  • happyyear Nov 19, 2008

    I have a similar problem. After 8 years in a drawer, I seldom get a signal. But now and then it will work for a few seconds.

    Mind reposting the solution?

    Its nice solder iron shown in provided link and that should be 30 Watt.
    If you have good solder skills then you can do this job easily.
    Good luck.

Would like codes for the area of 56573

If you need a S.A.M.E. code, NOAA does these by county.

The zip code of 56573 is part of the county of Otter Tail, Minnesota, assuming no typing errors are involved. Thus the S.A.M.E. code is 027111 . Several transmitters cover this region 162.400 (channel 1), 162.500 (channel 5), 162.550 (channel 7), and 162.525 (channel 6) . However, the best transmitter choice is probably Channel 5 (162.500 WNG680) from Fergus Falls. The second best choice for Perham, MN is Channel 1 (162.400 Detroit Lakes WXM64 but it is a low power transmitter). See the link to the coverage map below.

All S.A.M.E. codes are available here: . Click on your State and then look for your county. The Minnesota S.A.M.E. codes are listed here: . To see the coverage zones for each of the transmitters, see (the link to the coverage map is also on the County S.A.M.E. code list page on the left hand side of the page.

Otter Tail is a large county and none of the transmitters seem to cover every inch. So you will need to try your weather radio and see which transmitter gives you the best reception of tests, watches and warnings.

I hope this helps.

(who has several weather radios in the house. They are in different areas and set to receive different transmitters. I live near a county line and the signal strength depends on where in the house you are. We tried using an external antenna. We received the signal from a transmitter from another state at the desired frequency and didn't receive the local warnings.)

I have used my Grundig S350 radio almost daily, for the past 6-7 years. I went on vacation for 10 days. When I returned home, I turned on the power, lights light up, etc., but no matter how...

Its microcomputer chip may have hanged. Just make a reset ans see whether it helps you. It must help you, i"m sure. To reset it;

S350 incorporates with micro computer chip (the component that

controls how the radio operates). If the radio has been subjected to

abnormal environmental conditions, the micro computer chip may
hang up and the following symptoms may appear

The display shows nothing and the radio cannot be turned on by
pressing POWER & SLEEP button.

The display shows random characters or does not work properly

although the radio can receive stations normally.

In these cases, you might need to reset the radio. To reset the

S350, unplug the external adaptor (if one is being used) and

remove the batteries from the battery compartment. Insert a

pointed object, such as straightened paper clip, into the RESET hole

on the right, front side of the radio and gently press and release the

button inside the hole. Then plug in the AC adaptor or reinstall the

Cd is stuck

It would certainly help if we knew the year and radio model.

06 and newer it could be a bad CD drive or a faceplate PCB issue not allowing the signal to get to the drive.

With power button pushed radio will not turn on.

Would help if we knew what year.
Check the supply fuse and check to see if you have power at the connector. If yes to both, it's an internal issue.

Tivoli Model One Radio Humming only, no reception

The fuse would cause a total absence of power. Your problem is likely a blown filter capacitor in the power supply. Unless you have electrical/electronic skills, the radio will require professional repair.

On my 2003 ultra classic the left speaker on the fairing goes on and off and the right speaker sometimes pops and sometimes does nothing the speakers on the tour pack work fine. when i use the channel...

Check for loose wires on front speakers (remove faring, 7 screws). The popping one may be blown.
Try some electrical contact spray on the handle bars control switch, and then work the switch.

No sound after dropping S350.

Probably one of two things:

The dropped caused the speaker leads from the PCB to Speaker to disengage (check the earphone jack, too... 'cause it is in the circuit)


The bounce cause the Audio amplifier IC to become desoldered from the PCB.

Radio not working

Have you tried changing the AA Batteries, sounds simple, but a lot of people forget to try this. When they go flat, they lock the radio out and nothing will work. HHM Dewalt Agent
