SVXLink Analog Transceiver2 — Raspberry Pi Zero 2 W Bundle (UHF 70 cm)

The SVXLink Analog Transceiver2 is a cutting-edge HAT designed for the Raspberry Pi Zero. Equipped with a UHF 70 cm band radio module and Wolfson DAC/ADC, it can function as an EchoLink/SVXLink analog hotspot, an SVXLink simplex repeater, or even an APRS digipeater. Combined with AnalogBridge (DVSwitch), it provides seamless access to BrandMeister, OpenDMR, and other networks.

Measurements

All tests conducted with a calibrated Vector Network Analyzer (VNA) and 36 dB attenuator. Worst-case harmonic: −63.56 dBc (3rd), far surpassing ETSI EN 300 220 (≥43 dB below carrier for ≤30 dBm TX). This offers an extra safety margin of >20 dB. Spectrum confirms excellent spurious suppression and clean transmission inside the 12.5 kHz channel.

Compared with top brands like Kenwood, Icom, and Yaesu, our module demonstrates superior spectral purity, placing it on par with commercial-grade equipment.
