SVXLink Analog HotSPOT 70cm UHF
Experience the power of the SVXLink Analog Hotspot, a cutting-edge HAT designed exclusively for the Raspberry Pi Zero.
Packed with a formidable 0.5W/1W UHF (70cm) 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 hotspot.
What's more, with the combination of a remote SVXLink with AnalogBridge (DVSwitch), you gain access to digital networks, including the Brandmeister and OpenDMR network, unleashing a world of limitless possibilities.

We advise to use the analog hotspot only with 0.5 Watt output power and with the delivered RF.Guru NoTenna !
For those planning to connect their hotspot to a base antenna, we strongly advise incorporating an additional band filter. This essential component acts as a safeguard, preventing any potential signal interference due to harmonics.
