Elecraft Frequency Memory Editor Software

The Elecraft Frequency Memory Editor helps you maintain frequency memories using a spreadsheet format. It supports the KX2, KX3, K3S and K3 radio systems.

Memories can be recalled using K3, K3S, and KX3’s M>V switch or the memory editor’s “QSY” buttons.

Once memories are stored in your KX2, K3S, and KX3, you can disconnect the KX2, K3S, and KX3 from the PC. You can even maintain sets of memories in PC files and share them with other KX2, K3S, and KX3 users.

The program can be used by K3, K3S, KX2 and KX3 owners, and the saved files can be shared without regard to the radio type. The KX3 has a broader range of acceptable 2 meter frequencies than does the K3/K3S

 K2 Voice Main Screen


K3 Voice and K2 Voice are voice feedback programs for the K3 and K2. They run under Windows 95,98, 2000 & ME. (And vista for K3 Voice). They are provided free, without warranty or ongoing support for your use. K2s will require the KIO2 option.
Our goal is to make the K3 and K2 useful for hams who are unable to see the normal controls and displays. It will report most common operations on using the soundcard in your PC. Both programs report the frequency, mode, filter selections, split, VFO a/b etc.

The Programs operate in one of three modes:

  • Fully automatic: All button presses and frequency changes made on the K2 are automatically reported within one second of completion. VFO frequency changes are reported after tuning has stopped for one second.
  • Semi Automatic: Same as above except the VFO is not automatically reported. Press a key to get the current VFO frequency.
  • Manual: Press a key for each function to be reported. for example, press ALT- F to get the current frequency, ALT-M to get the current mode etc.
