Software Setup

Enable Ultra Mode

Enabling "Ultra" mode will allow you to increase the range of the device from 900MHz to 7.3GHz.

Tap on the screen, then click "Config".

Click "More".

Click "Enable Ultra".

Ignore the popup.

Click "Enter".

Add Waterfall

The waterfall will allow you to differentiate different signal types.

Click "Display".

Click "Waterfall", you can click it three times to go from 1/4, 1/2, 3/4 parts of the screen. I recommend 1/2.

Active the LNA

To increase the sensitivity of the device, we want to active the LNA.

LNA stands for Low Noise Amplifier.

DO NOT USE AN EXTERNAL LNA WHILE THE INTERNAL LNA IS ACTIVE!

Click "Level".

Click "LNA".

Enable Multi-Band

You can view multiple ranges of frequencies instead of just one range, let's active that and use it to view the typical VHF and UHF bands used by popular walkie talkies.

Click "Frequency".

Click "Multi-Band".

Setup VHF

Click the first band.

Click the "Start" frequency.

Enter 136 MHz.

Click the "Stop" frequency.

Enter 174 MHz.

Setup UHF

Click "Back" to go back to the band list, then click the second band.

Click the "Start" frequency.

Enter 420 (Nice) MHz.

Click the "Stop" frequency.

Enter 470 MHz.

Add second Trace

The yellow line shows the current RF energy detected on that frequency, we can also add a red line that holds the maximum frequency detected. I prefer the "Max Decay" setting instead of the "Max Hold" instead. The "Max Decay" setting is similar but the line will decay if a signal has not been detected on that frequency for a while.

Click "Trace".

Click "Trace 1".

Click "Trace 4".

Click "Enable".

Click "Calc Off".

Click "Max Decay".

Save current settings for startup

All these settings will not be remembered on power cycle unless we save it as the "Startup" preset.

Click "Preset".

Click "Store".

Click "Store as Startup".

There is no need for a name, just click "Enter".

If you power cycle the device, you should have all the same settings.

Usage

This device is capable of receiving a wide range of the radio spectrum, but antennas are limited. If you use an extendable antenna, you will need to adjust the antenna to the band you are listening for. If you use a specialized antenna for a specific bands, you will have trouble receiving signals on other bands unless they are really close.
