Page 6: Installation And Tests
ELEKTRA 2500 HAMTRONIX INSTALLATION AND TESTS TURNING ON THE CONTROLLER FOR THE FIRST TIME Be sure the jumper J5 is in S (Squelch) position and J3 in negative position (-). Close SW1 terminal. If you hear the transmission of a melody, the connections between controller and transmitter are correct. Turn the squelch (SQL) trimpot fully counterclockwise. -

COR signal. VIRTUAL ASSITANT Elektra 2500 is compatible with Virtual Assistants for Artificial Intelligence (Google Home, Amazon Eco etc.). This allows you to ask questions through the repeater and get answers on a multitude of subjects. You can ask for the weather forecast, ask for general information and even schedule ads for specific times. -
Page 8: Repeater Audio Fidelity
ELEKTRA 2500 HAMTRONIX REPEATER AUDIO FIDELITY The fidelity of the retransmission audio not only depends on the audio circuits of the controller, but where you get it from and where you send it to. De-emphasis and Pre-emphasis Before an FM transmitter transmits the audio on the air, the audio coming from the microphone must pass through a pre-emphasis circuit. -
Page 9: Repeater Transmitter Enable
01 – REPEATER TRANSMITTER ENABLE (Default = 1) This is the master repeater switch. This function must be enabled for normal repeater operation. The Elektra 2500 will continue to respond to DTMF commands and identify even when the repeater's transmitter is disabled. This function will automatically be enabled after a reset or power up. -
Page 10: Roller Beep
Note: This function should only be activated if there is a CTCSS decoder installed. It can be external such as the Hamtronix TED300 module or from inside of the receiver. TONE1 input (CN2-6) is active with logic level 0 (voltage less than 0.6V) when the correct PL/CTCSS is present. -
Page 11: Id Timer
ELEKTRA 2500 HAMTRONIX 14 – ID TIMER (Default = 1) Determine how often the ID (voice or CW) will be transmitted. 0 No ID 2 Every 10 min 4 Every 20 min 6 Every 30 min 8 every 3s 1 Every 5 min... -
Page 12: 19 - Voice Id Message Recording
ELEKTRA 2500 HAMTRONIX 19 – VOICE ID MESSAGE RECORDING The maximum recording time is 20s. If you choose Smart ID (function 15-2), this time will be split in two, resulting in two 10s messages each. After sending the command, release PTT switch and the next key up will be recorded and played back after recording. -
Page 13: Simplex Repeater
ELEKTRA 2500 HAMTRONIX 25 – SIMPLEX REPEATER (Default = 0) Does not require separate receiver and transmitter. Even an HT can be used for this. When enabled, any incoming signal will be recorded and played back. The duration of each transmission should not exceed 20s or it will be cropped. -
Page 14: 36 - Reset
ELEKTRA 2500 HAMTRONIX 36 - RESET Restart the microcontroller with user programmed values. A melody is heard to indicate a successful reset. Have the same effect as power up. Ex: 123436# Note: The voice message and CW programming are not affected. -
Page 15: Troubleshooting
ELEKTRA 2500 HAMTRONIX TROUBLESHOOTING In case of malfunction, perform a Full reset so that the values programmed by the manufacturer are reestablished. In this way all options of the functions return to the default values. It can be performed in three different ways: 1) Over the air, using a function 37: Enter: 123437# 2) Over the air, using the master password. - Page 16 Serial Number 2592 Firmware Version 2.52 Master Password 0592 Hamtronix www.hamtronix.com www.hamtronix.com.br 2000 - 2021 ©...
