Programming Presets in PRC-104B

PRC-104B Frequency Loading

1. Turn radio on
2. Set to the first frequency you desire to save in a channel.
3. Set the desired mode, usually VTR (Voice Transmit Receive) and Sideband mode (LSB or USB).
4. Then press both mode buttons at the same time to get to the scan and channel menu.
5. Select STO. The display will then show 1/2/3/4/5/6, the potential channels to store a frequency.
6. Select the desired channel and the frequency will be stored in that channel.
7. Repeat as desired for the remaining channels

Confirm Presets

1. Press both mode buttons at the same time
2. Select the RCL button from the scan and channel menu.
3. 1/2/3/4/5/6 will be shown.

When you select the channel in which you had previously stored the frequency, it should again re-appear along with the correct modes.

Example

18157.5 KHz into channel 6

1. Turn Radio on
2. Set operating frequency to 18157.5
3. Set mode to USB and Mode to VTR
4. Now press both mode buttons at once to enter the scan and channel menu
5. Select STO and when you see 1/2/3/4/5/6 select 6
6. The frequency 18.157.5 is now stored in Channel 6

Example PRC-104B Preset Frequency List

3	7296	USB	VTR

PRC-104B Frequency Recall

1. Enter the frequency recall mode by again pressing both mode buttons at the same time.
2. From the Scan and Channel menu depress the RCL button
3. 1/2/3/4/5/6 will be displayed. When you select a channel in which you had previously stored a frequency, it should again re-appear along with the correct modes.

PRC-104B Frequency Scanning

1. Enter the SCAN Channel Menu by depressing both mode buttons  together
2. Select DWL and Set DWL (Dwell) to 1 – I like this because the radio will dwell on frequency for 1 second before moving on to the next channel.
3. Enter the SCAN Channel Menu by depressing both mode buttons  together
4. Select SCAN and the radio will begin stepping through the channels starting with the one in channel memory 1 and going to 2 then 3 then 4 then 5 then 6 then back to 1 in a repetitive fashion.
5. When you hear conversation on a channel and wish to stop, depress the ENT button on the scan menu and the radio will stay on the selected frequency and go out of the scan mode.
6. To re-enter the scan mode, again depress both of the mode buttons simultaneously and then depress the SCN button.
