AM Broadcast Stations
This radio has an optional Module, shown above, that can be used to allow you to play music from your Smartphone or listen to your local FM Station. One of the problems for collectors of vintage radios is that there are very few AM Stations left in North America.  As a result many valuable radios sit idle. There radios are designed to be operated on a daily basis. To enable daily use Old Fidelity adds a module, hidden on the back of the radio, that allows the radio to play FM Stations as well as music on a smart phone via Bluetooth. The module is accessed via a switch on the back of the radio. Once the radio is in the module mode, you can choose from FM or Bluetooth using the module switch.
 
When using the module the radio's on-off switch, volume and tone controls are fully active. The signal strength can also be adjusted by controls on the module. The great value of this set up is that you can use this radio on a daily basis to seamlessly play your local FM Station. When you turn the radio off, using only the radio's on-off control, while playing an FM Station, it will continue playing that FM Station when you turn the radio back on. You only need to touch the module if you want to change FM Stations. This is done by the module control labeled "FREQ". This versatility enables the everyday use of this radio whether or not an AM Station is available in your area.
