The Radio Programmer Is for so Much More than Just Memory Management.

With the WCS-R20 Programmer you can begin a new “factory fresh” file into which frequencies and option settings are entered. Or, you can read from the radio, store these details on your computer and make changes. Then, with minimal button pushing, send the new configuration back to the radio.

The Programmer allows you to create and save as many files as you want for your radio. Files can even be shared between users via email or the Internet.

Managing all the options of this radio becomes easy with the Programmer. The cut, copy, paste and insert features of the Programmer make channel management easier than ever.

Open more than one file at a time. Memory channel information can be copied from one file to another within the Programmer making it really easy to set up a new file.

Limit Memories

Limit Memories are used by the radio for Program Scan. Program the same details for Limit Memories as for regular memory channels. Many of the Limit Memories are preprogrammed in the radio and while the frequency can be changed to another within the band, they cannot be left blank.

Auto Write Channels

These memory channels are stored automatically when Auto-memory Write Scan is used on the radio. Auto-write Memories are lost from the radio if you clear the stored channels to scan again. They become permenant only if they are saved as regular memory channels. Use the Programmer to easily move the ones you want to save permenantly to the regular Memories with copy and paste.

TV Channels

Available TV channel frequencies depend on the radio’s version. This screen in the Programmer will be populated with those frequencies specific to your radio model once you complete Communications | Get data from radio. Make changes to these channels to suit your area and activities. The Channels can be deleted from the list to remove them from the radio. The Instruction Manual for the radio details these frequencies for all the different models should you need to recreate the list for your radio.

PreSet Channels

Ten memory channes are designated for quick recall of favorite frequencies you use most often. Use the Programmer to easily fill these with selections from other types of memories using copy and paste. No need to ender details again for a favorite channel.

Radio Settings


Use this screen to customize other set menu features of the radio. Check boxes toggle features on or off, drop down menus list all selections and blank boxes for personalized entry add to the ease of setting up your radio exactly like you want it.

The entries on the Settings screens are made for you to “Set and Forget”. Once settings are customized, you are prompted to save before exiting. The saved settings will be there every time you create a new frequency file.

Preferences Customize the Programmer

Grid Display

  • Freeze columns to keep information on the screen as you scroll to the right of the page.
  • Hide columns you don’t use. Customize your printout: hidden columns do not print.

Memory Defaults

  • Set options to control the font in the column headers of the channel entry screens. Select any font and font size available on your computer.


  • Set options to control how the programmer handles the global Radio Menu Settings file.
    - Separate (default) handles the global settings of the radio in a “set and forget” fashion. Once you set these up and save the file you won’t have to reset them for a new frequency file.
    - "Single file" gives you the ability to create files that are complete with frequencies and customized global settings. In this mode, each file begins with factory defaults for every option of the radio.
  • Check “Get data from Radio” new file option to prevent data loss when you read from your radio into the programmer.
  • Check “different window” option to make the programmer for a different radio run in completely separate window rather than in a separate tab of the same window.
