Page 4: General Information
General information The TX-500MP transceiver is a compact, portable HF radio in a manpack form factor, designed for professionals and enthusiasts who prioritize mobility, operational efficiency, and extended autonomy. The transceiver is based on the time-proved and reliable TX-500 platform. Transceiver is engineered for operation in harsh conditions: a durable, aviation grade aluminum alloy housing precisely milled to protect against mechanical damage, and the absence of through-holes prevents dust and moisture ingress. -

Page 11: Connection And Control
Connection and Control GETTING STARTED Connection 1. Connect the speaker-microphone to the MIC/SP port. 2. Connect the antenna to the ANT port. When connecting an antenna directly to the transceiver's ANT connector (without a coaxial cable), a counterpoise of at least 2.5 meters in length is required (the optimal length is 1/4 of the wavelength of the operating frequency). -
Page 12: Basic Control
Connection and Control BASIC CONTROL On-Screen Menu The transceiver’s basic functions are accessible via the on-screen menu panel. Functions are distributed across multiple on-screen rows, and menu screens can be switched using the left/right keys. VOL/LCK FREQ TUNE Function selection is performed using the corresponding function key (F1-F3). The currently active function will be displayed inversely (background color changes) and will remain active after the next power-on. - Page 13 Connection and Control TIP: Activated functions remain active after the transceiver is turned off and on again. For example, to keep volume adjustment enabled by default, leave it active—this way, the UP/DOWN keys will adjust the volume automatically on subsequent power-ons. Squelch Threshold Adjustment (SQL) The squelch function suppresses receiver audio until a valid signal is received from a correspondent, eliminating background noise and radio interference.

Page 14: Vfo Mode
Connection and Control VFO MODE In VFO mode, users can adjust the frequency, select modulation, set filter bandwidth, and configure other parameters. VFO mode is the default operating mode. To switch to VFO from channel mode, select the option in the on-screen menu by pressing the corresponding function key. -
Page 15: Channel Mode (Ch)
Connection and Control CHANNEL MODE (CH) In channel mode, users can access 100 programmable memory slots—channels, each storing frequency, modulation, and other settings. Channel mode (CH) can be activated if channels have been pre-saved, using one of the following methods: pressing one of the quick access keys (CH0, CH1, CH2) or selecting the on-screen menu using the corresponding function key. -

Page 17: Reception Settings
Connection and Control To enable CTCSS in transmit mode (TX), activate the menu item in the lower on- T_CT screen menu. The icon will appear on the screen. To configure the subaudible T-CT tone, go to the main menu, select CTCSS > TX and set the tone frequency using the UP/DOWN keys. - Page 18 Connection and Control To set the tone frequency, go to the "CTCSS > RX" section in the main menu and use the UP/DOWN keys to select the desired frequency. • Virtual Intermediate Frequency (DIF): This setting defines the receiver mode and is activated in the main menu under DIF.

Page 19: Antenna Tuner (Atu)
Connection and Control ANTENNA TUNER (ATU) The TX-500MP transceiver is equipped with a built-in antenna tuner (ATU) that matches antennas with different impedances. By default, the tuner is in bypass mode (BYPASS) and inactive. To enable the tuner, press the function key corresponding to the menu TUNE item in the transceiver’s on-screen menu. -
Page 20: Advanced Control
Advanced Control RECORDER FUNCTION The transceiver supports the recording and playback of short voice or telegraph messages up to 20 seconds long. Two separate memory slots are available for storing each type of message. Record: Messages recorded corresponding modes: USB/LSB/FM/AM for voice and CW/CWR for telegraph. -

RF RF Gain Level The gain level is adjustable independently for each mode: CW / SSB / DIG / AM / FM. Select the mode using the SubMenu F-key and adjust the value within the range of -50 to +5 based on personal preference and reception conditions. - Page 25 Menu Functions 08. CMR LVL Speech Compressor Level (SSB only) Adjust in the range from 1 to 100 based on personal preferences and reception conditions. Typically, the maximum compression level is 40. Default: 5 09. EQL Equalizer The equalizer allows adjusting the levels of high (HF), mid (MF), and low (LF) frequencies for both TX and RX modes independently.
- Page 26 Menu Functions 14. NB LVL NB Level Adjust the filter level between 1 and 100 for optimal noise suppression. Default: 50 15. NR Enabling Noise Reduction The Digital Signal Processing (DSP) function for noise reduction is most effective in CW mode and may slightly reduce signal accuracy in SSB mode. Set to ENABLE or DISABLE to activate or deactivate the noise reduction function.
- Page 27 Menu Functions receiver. Set the tone frequency independently for TX and RX modes. Select TX or RX mode using the SubMenu F-key and adjust the tone frequency between 67 and 254 Hz. Default: 100 22. DIF Virtual Intermediate Frequency Due to the nature of internal signal conversion, several frequencies may emerge as tones that interfere with reception at specific frequencies.
- Page 28 Menu Functions 28. CW WEIGHT Dot-to-Dash Ratio Select the dot-to-dash ratio from 2:1 to 4.5:1 Default: 3:1 29. CW DECOD CW Decoder The transceiver includes a CW message decoding function in both RX and TX modes. Select the decoder mode (TX or RX) using the SubMenu F-key and set to ENABLE or DISABLE to activate or deactivate the function.

Page 30: Safety And Protection
Safety and Protection SAFETY REQUIREMENTS • Do not connect power sources with specifications that do not match the required ones, as well as non-standard (DIY) power sources. • It is prohibited to connect an antenna to the device during lightning discharges, as well as during strong gusts of wind that cause static discharges. - Page 31 Safety and Protection WARNING! In prolonged transmit mode (digital modes), do not obstruct airflow to the rear panel of the transceiver and/or reduce power output.. TIP: Extend both rear legs to enhance air convection.. High SWR Protection If the antenna impedance differs from 50 ohms and an antenna tuner is not connected, the SWR indicator on the display will show a value greater than 1.0.
