2023-K-141-U | Kit - SVXLink Analog Transceiver 70cm UHF 1.3W 13.8v

This kit requires some soldering skills !

Also available assembled !

Also available as a pcb ! 

Experience the power of the fully assembled Analog FM Transceiver HAT. 

Attach a 13.8 power source and off you go ! 

This device incorporates an LTTC low pass filter and complies with regulations!

Packed with a formidable UHF 70cm band radio module, this versatile device is accompanied by a state-of-the-art DAC/ADC, enabling it to function flawlessly as an EchoLink/SVXLink analog simplex repeater or hotspot.

The board includes an on-board low-pass filter designed to block harmonics from reaching the antenna output. This enables seamless connection of the transceiver module to an outdoor antenna, without encountering any problems. Additionally, it provides the option to drive a PA for enhanced output power capabilities.

What's more, with the combination of a Raspberry PI Zero 2W and SVXLink with AnalogBridge (DVSwitch), you gain access to digital networks, including the Brandmeister and OpenDMR network, unleashing a world of limitless possibilities.

This module can also serve as a remote transceiver module, featuring remote speaker and microphone functionality.

Measurements

Due to the added low pass filter, the board meets regulations (ETSI EN 301 783) and can be used on an outdoor antenna !  The spurious emissions are -47 dBc less then the fundamental frequency and is far more then the (43+10*LOG(1.3)) = -44dBc requirement !

Antenna

The Nagoya Dual 810DP Nagoya Dual band antenna is included.
