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. Our advanced digital signal processing

combined with IQ / quadrature demodulation delivers superior performance. Our

receivers are the first and only non-subscriber units that are capable of

monitoring the new “TDMA CC” systems starting to be deployed in multiple areas

of the country. The initial release of the MicroP25RX receiver is designed to work

with the SeeedStudio Wio Terminal Display. The BlueTail Technologies source

code for the display is available under a permissive MIT license. Users are

encouraged to fork the source from github and make modifications. The

enclosure is available as an option. The MicroP25RX has advanced features

such as location-based-scanning via zip code entry. Enter a US zip code, a

search radius in miles to search an FCC database on the SD card for all the P25

systems in your area. For systems not contained in the FCC database (state-

based systems, federal systems , there is a separate file that can be edited for

use with the zip code search. As the receiver learns new network information

from the control channel, the information is written to a robust, flash-based file

system. The file system utilizes a journaling technique to prevent file system

corruption during power supply glitches. Other advanced features are talk-group

zones, RID-alias display per system, talk groups per system and multiple

scanning / roaming modes that allow monitoring a single system with rotating

control channels or multiple systems with different configurations from VHF to

UHF bands. Talk group backup files from the P25RX/P25RX-II can be imported

from the SD card. RID-alias files, DSD-formatted talk groups files, and site files

can be imported from the SD card. The BACKUP function creates an ini-style text

file and contains 100% of the device configuration (including network, talk

groups, alias, calibration, etc The backup file is human readable and can be

edited in a text editor if desired. The restore function can be used to clone a

device. Other than transferring files to the SD card, a PC is not required for

configuration.

3.0 Attaching The Wio Terminal Display

The Wio Terminal must be removed from the 40-pin connector in order to install

the enclosure cover. The cover is installed while the receiver pcb is slid up to the

edge of the plastic enclosure. The Wio Terminal Display goes on last when

assembling and comes off first when disassembling. The rubber pads are placed

approximately where shown on the pcb or can be installed on the backside of the

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.

4.0 Button Mode Selection

Please read this section carefully. Button mode selection determines the

mapped functions of the buttons. Button Mode Selection can be entered by

pressing in on the joystick button. Available modes are MONITOR, CONFIG, and

TG ZONE. Selecting each of these three modes changes what the buttons do.

This may not be immediately intuitive, but is necessary to expand the

functionality of a limited number of buttons. Note, when ROAMING MODE=5 and

the mode is CONFIG MODE, the top buttons are mapped differently for fine-

grained selection of which sites to scan.

4.1 JOYSTICK BUTTON

The joystick button is a 5-way switch, left/right, up/down, pressed-in.

When the keyboard entries are displayed, the joystick is used to determine

which alpha/numeric values are to be selected. Pressing the button is the

select function. Keyboard entry options are either aborted with the top-

middle button or completed by selecting the ENTER key followed by

pressing the joystick button inward. 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.

4.2 MONITOR MODE BUTTON-MAPPING

In monitor mode, the button mappings are:

Button-A = TG Follow/UnFollow (will display an ‘H’ indicator when holding

Button-B = AUDIO Mute / UnMute (will display an ‘M’ indicator when muted

Button-C = Skip TG for 60 seconds

Note: The receiver only scans in monitor mode. Displays: “ROAM-ON-X”

4.3 TG ZONE MODE BUTTON-MAPPING

In TG Zone mode, the button mappings are:

Button-A = Enable / Disable Zone

Button-B = Rename Zone

Button-C = Return To Monitor Mode

4.4 CONFIG MODE BUTTON-MAPPING

In Configuration mode, the button mappings are:

Button-A = Enable / Disable LEARN MODE

Button-B = Display Configuration Menu

Button-C = Site Demodulation Selection LSM / FM

Except when in ROAMING MODE=5, then

Button-A = Include In Scan (will display ‘S’

Button-B = Display Configuration Menu

Button-C = Exclude From Scan

Joystick left-right cycles site frequencies, up-down cycles secondary sites.

4.4.1 Configuration Menu

4.4.2 ZIP CODE SEARC

Zip code Search will scan frequencies around your area and add active

control channels to the receiver configuration. The 5-digit zip code is used

to look up latitude / longitude coordinates from a file contained on an SD

card (on the receiver . The next prompt is for the search radius around the

lat/long that you would like to search. The search radius is a filter that

limits search results from the records in the FCC database files to be

within the specified distance in miles. The site records are contained in

two files on the SD card, freqs.csv (FCC records , and an optional file

named freqs_user.csv. 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. After the zip search is completed a message will appear on

the display to indicate this, then the device will switch to roaming mode 1,

monitor mode. If all went well, you should now be scanning all the

discovered P25 systems in your area.

4.4.3 ADD P25 SYSTEM

Add P25 System allows entering a known control channel frequency

manually. The decimal is automatically added after entering the first three

digits. After entering the frequency, the receiver tunes to the specified

frequency and enables LEARN MODE in order to discover network

configuration information transmitted by the control channel.

4.4.4 EDIT

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.
