YaV1 Valentine App




The Valentine One radar detector in the last two years has undergone significant improvements, and the Valentine One Extended Serial Protocol (ESP) has paved the way for specific user customization options never before offered.  In firmware versions 3.892 and higher, ESP has allowed for external accessories such as the SAVVY and the V1Connection modules. The V1Connection module allows users to customize their detector by fine tuning specific frequency ranges during scanning, which improves the efficiency and response time by the detector.  However, the app provided by Valentine One does not offer advanced user customization features like the YaV1 app.  The YaV1 is an Android app developed by one of our members, “francky06L,” for the Valentine One detector (firmware versions 3.892 and higher) that offers general and advanced configuration settings to fine tune radar detection performance, and allow users to minimize false alerts using GPS enabled lockouts.

YaV1 Alert View Screen

This is the Alert View Screen that most users will use to identify and assess threats on their phone.This screen will provide users all the technical details of their environment such as:

  • Profile – Bottom of the screen
  • Threats by type – Laser, Ka, K, X, Ku, and in order of priority

This is the V1 View Screen that provides the same standard type of alerts as a V1 Concealed Displayand display from the Valentine One detector displayThis screen will provide users all the basic details of their environment such as:

  • Threats by type – Laser, Ka, K, X
  • “Bogey Counter” – numeric in the left of the screen (i.e. “2” in this example)
  • Signal Strength
  • Frequency
  • Direction arrow for highest threat – Red for front, Yellow for rear, green for side threats

Programming Your Valentine One with YaV1


The following three videos will provide users a quick walk-thru of the of the YaV1 app, and guide users on how to get started using the YaV1 app for their Valentine One using some basic presets.




YaV1 – Preparing For Battle

The YaV1 has several features ranging from user-specific screens showing alerts, using GPS Lockouts for filtering false signal sources, and allowing users the highly valuable band segmentation option for custom sweeps. Familiarization with these features will provide users an enjoyable experience on the highway and enhancing the radar detection performance of their Valentine One detector.

When enabled, Filters View will not allow locked or filtered alerts to be visible if appropriately checked.Ka, K, and X-band frequencies can be filtered with this feature.There are 4 settings for filtering in this setting:

  • Filter Lockout – filters lockouts from K and X band from view in Filters view
  • Filter Ka – filters Ka-band “in or out of box” choices
  • Filter K – filters K-band “in or out of box” choices
  • Filter X – filters X-band “in or out of box” choices


Lockouts and SAVVY

Lockouts and SAVVY Emulator
The YaV1 excels at locking-out false alerts with the best precision of any app currently available.The YaV1 Lockout Setting contains the following options:

  • Lockout K/X – When enabled, users have many choices to setup false alert lockouts; K and X-band can be locked or unlocked with the quick touch of an alert frequency. Another quick touch while the alert is still present will unlock the locked-out frequency
  • Ka Lockout – When enabled, the above rule also applies to Ka-band alerts, so use with caution
  • Radius – Allows variance in lockout radius size “in yards” from GPS point where lockout is first activated. The default is 218 yards.
  • Enable Bulk Lockouts – Activates the orange round button on alert screen so that if touched, every alert frequency displayed will be locked out per prior options (K,/X and/or Ka).


Frequency Boxes

YaV1 Frequency Boxes

The YaV1 can fine-tune detection with the user input.  Users basically set what frequencies they want their Valentine One detector to scan.Setting Frequency Boxes highlights the frequencies encountered in a user-specified color that makes determining threats a simple task.

  • Enable Boxes – When enabled, this feature allows users to set color-coded boxes around specified frequency ranges. In this example, the darker green is a higher threat than then the lightly-colored green, however, this still provides the user notification to be careful due to a potential gun that may be out of tune and still within range


Custom Sweeps

YaV1 Custom Sweeps

Users can setup custom sweeps for segmenting Ka-band better than any radar detector currently available.Custom Sweeps instruct the Valentine One to only scan portions of the Ka-band most commonly used by speed enforcement radar units. By minimizing an entire range of potential Ka-band sources, Custom Sweeps allow users to program the detector to specifically scan the most common frequency ranges from radar units.  This provides a quieter detector that is also more responsive.

  • The following picture to the left is considered safe in all parts of the the USA.
  • The only exception is the 35.2 GHz band that is used by old and outdated radar units occasionally used Oregon and Washington
  • Please view pages 14-16 of the the YaV1 user manual

YaV1 Logging Radar Alerts On Google Map

YaV1 users have the option to also keep track of their radar encounters.  The app works with Google Maps and logs the following information:

  • Frequency
  • Time
  • Speed
  • “Hits”


The format “K 24130 (+/- 6)” indicates an alert of 24.130 GHz with a tolerance of +/- 6 MHz.
