Lost all radio stations on my Sherwood RX4030R

What's the make & model of the radio?
Most DAB/FM radios work from the same antenna, so if you receive FM stations, you should receive DAB stations in your area.
It should be noted that DAB transmitters work on lower power than conventional FM transmitters, and so you may be in a weak reception area (for DAB). It should also be noted that DAB uses different frequencies than regular FM stations and household appliances such as laptops,WiFi, microwave ovens, etc can affect DAb reception.

TAKE THE KNOB FO AND SEE IF IT WILL TURN BUY HAND IF SO JUST PUT A BIT OF PAPER ROUND IT AND PUSH THE KNOB BACK ON AND IT SHUOD GO

Car cradle works "wirelessly" with Car Radio (inherent design of unit). Place Unit in Cradle; connect Cradle to Auto Power Source, and SkyFi3 should power on. Press Menu to Get FM Radio station channels; select a lower station Channel Frequency i.e. 88.3 or any vacant channel number and the signal should transfer to your Radio speakers automatically. You can change Station frequencies as often as you need to do so--for example if traveling through different broadcast areas, some channels frequencies are clearer than others. Good luck.

Say goodbye to this unit if FM matters to you

You need to hook an antena to the back of the unit (A peice of speaker will do!) you should see a screw in back of uniGood luck and Thank you for using FixYa.

first you have to set a channel in your sat radio then tune your car radio to that channel go to menu and then to set fm frequency in your sat radio and choose one try to get one that does not have a station on it whatever you set it at just tune your car radio to that frequency and it will work

Check your antenna connections. Make sure your FM antenna is hooked up to the FM antenna terminal or jack on your Sherwood receiver. If you have the antenna hooked through the coaxial cable, check your coaxial cable with an ohmmeter for continuity. You can buy a volt-ohm meter as little as $12. Usually bad connection occur between coaxial cable and the the coax cable connectors. If that doesn't solve the problem, then there may be something wrong with your tuner card inside of your Sherwood receiver.

If you receivers display does not change channels or frequencies or AM or FM mode, when you try to change the channel or frequencies, or AM or FM mode, there may be something wrong with the front board of your receiver.

If there is something internally wrong your Sherwood receiver, you need to take it to a qualified technician that can fix it. Do not try to repair it yourself. If you don't know what you're doing, you can do far more damage to that Sherwood receiver to the point that would be very costly to repair.

Before you take your Sherwood receiver to a technician, try to unplug the receiver, and leave it unplugged for several minutes, and then plug it back in. If that doesn't solve the problem, then you need to take your Sherwood to a qualified technician.

Usually when you lose only AM it is an antenna issue. Check for a loose antenna plug on the back of the radio or connection to the antenna.

Make sure your receiver is hooked up to proper AM and FM antennae. Try switching to AM, scan stations. If you hear AM static and/or weak signals the problem could be antennas are not hooked up. FM has AFT which blocks out weak or noisey stations and you wont hear anything without ant.
