Doc Date: 11/13/2022 1.0 Introduction The MicroP25RX is a P25 Phase 1 / Phase 2 (TDMA) trunk-tracking receiver that is designed to work in challenging environments. BlueTail Technologies is the only American company producing non-subscriber receivers that are immune to issues related to simulcast distortion.
Wio Terminal Display • base / stand parts. These may be used to form a base for the MicroP25RX when it is not installed in the plastic enclosure. A light adhesive is recommended to attach these parts. e.g. RTV.
Wio Display. The pads provide shimming for the display when it is connected to the 40-pin connector. The 40-pin connector provides 5V power to the Wio Terminal Display and a 4-wire SPI port for full-duplex communications to the receiver. BlueTail Technologies MicroP25RX User Manual...
In the MONITOR and CONFIG modes, the joystick left/right, up/down movements are used to select frequencies. For menu selections, the up/down highlights different menu options while joystick-press selects the highlighted option. BlueTail Technologies MicroP25RX User Manual...

The freq_user file allows adding custom records to the zip search. The us_zipcodes.csv and freqs.csv files can be downloaded from BlueTail Technologies web site. When performing a search the LEARN MODE is enabled on the receiver. When learn mode is enabled, configuration updates from the control channel are written to flash memory.
The EDIT menu is a general configuration parameter menu. EDIT ALIAS – enter a text string to be associated with a particular radio ID. The RID / Alias is displayed on the bottom line of the display during a voice conversation. BlueTail Technologies MicroP25RX User Manual...
