These controls allow saving up to five (5) sets of radio frequency, mode and filter data which may be recalled at any time during the current session. Hovering the cursor over a control will display the control's function. See below for more description.



  • Non-persistent five (5) position LIFO (Last In First Out) memory buffer holding the following data.
    • VFO A frequency
    • VFO B frequency
    • TX VFO (A/B)
    • Mode
    • RX1 Antenna
    • RX2 Antenna
    • TX Antenna
    • TX Line (TX1-3)
    • RX Filter
    • TX Profile
  • Recall & Load memory data as needed
  • Clear all memories
  • VFO <> Memory swap
    • Toggles current VFO A frequency, RX filter and mode with the selected memory slot.


  • V<>M - Exchanges VFO and selected memory data (toggle).
  • ReCall - Pressing this button repeatedly displays frequency, mode and memory number for each of the five (5) memories.
  • Load - Sends selected memory data to PowerSDR.
  • Save - Saves current frequency and profile data to #1 memory slot.
  • Clear - Erases all memory data.

Memory Note

As a way to attach a reminder note to the memory slot displayed the following method is available.

  • Double-Click the Frequency window just below the ReCall button.
    • Alternately, press the [Ctrl + N] keys to open the Memory Note window.


  • Fill in the note text as desired and press OK.
  • The Memory Note will be stored with the memory information and recalled and displayed with the memory data.
  • Display
    • The Memory Note is displayed in the title bar of the Misc form.


Notice! - This is volatile (non-persistent) memory. It lasts ONLY for the current DDUtil operating session.

Storing Memory Data

  • Tune to frequency to be remembered.
  • Press the ReCall button to select the desired memory slot to store the data.
  • Press Clear if not empty.
  • Press the Save button.
  • Button will blink Yellow when frequency and mode data are saved.

Alert! - If the memory slot selected is not empty memory slots 2-4 will be pushed down one level and the new data will be stored in slot #1.

  • Press the ReCall button to select the desired memory slot.
    • Repeatedly pressing in the ReCall button will page (rotate) through the five (5) memory slots.
  • Press the Load button to send the save memory data to radio.

Alert! - Pressing the Load button will replace current frequency and mode data in the radio. If you want to preserve the current radio frequency position use the V<>M button feature instead (see below).

Clearing Memory Data

  • Press the Clear button to clear the selected memory slot.
  • Pressing the key combination of Ctrl+Shift+Clear will clear all memory slots.

This feature allows you to move the radio to one of the stored memory frequencies without losing your current VFO frequency location. And then move back to where you came from when ready.

  • Press the V<>M button.
    • The V<>M button will turn Yellow.
    • The current VFO frequency will display in the window below the V<>M button.

  • Press the V<>M button again.
    • The radio will be returned to it's previous VFO frequency.
    • The V<>M button back ground color will return to normal.
    • The VFO frequency display below the V<>M button will be blank.
