Analog HotSpot - Transceiver
This refurbished Analog Transceiver/Hotspot gives you the same compact and robust hotspot platform at a lower price. These are units that came back to us because of a return, a replacement workflow, or a repair case. In many cases, there was nothing wrong with the hotspot at all. In other cases, we replaced parts such as the RF board or Raspberry Pi, then fully re-tested the complete unit.
Because we often ship replacement units before receiving or testing the returned one to save time for our customers, we regularly build up refurbished stock that is already repaired, checked, and ready to go. That means faster availability and better pricing, without changing what the unit is intended to do.
The platform itself is our 3rd generation Analog HotSpot, with the redesigned power stage, improved filtering, stronger thermal design, and a precision-machined aluminium enclosure. Output power is 26-28 dBm (~300-500 mW). The included NoTenna2 attenuates the output to an EIRP of roughly 50 mW by absorbing most of the RF energy. If you need more range, you can simply connect an external antenna.
It is a compact and robust analog communications hotspot built around a Raspberry Pi. Choose between the UHF 70 cm version (400–480 MHz) or the VHF 2 m version (134–174 MHz). Thanks to its Wolfson WM8960 DAC/ADC, it runs flawlessly as an EchoLink / SVXLink analog hotspot.
* Currently only an SVXLink Bookworm image is available for SVXLink and EchoLink.
Why Choose Refurbished
- Faster shipment — refurbished units are already assembled, repaired if needed, and tested.
- Better pricing — same product class, lower cost than a new build.
- Fully checked — every unit is verified before it leaves here again.
- Repaired where necessary — defective subassemblies such as the RF board or Raspberry Pi are replaced when needed.
- No compromise in intended use — same hotspot concept, same software support, same core features.
3rd Generation Hardware Platform
- Improved DC filtering — additional LC filtering stages drastically reduce noise and ripple on the power line.
- Enhanced thermal design — precision aluminium top enclosure for superior heat dissipation during continuous-duty operation.
- Reinforced RF chain — cleaner TX signal, improved stability, and excellent spurious suppression.
- Mechanically stronger housing — the aluminum enclosure includes a dedicated antenna aperture to allow Wi-Fi operation while maintaining overall shielding effectiveness.
- Included NoTenna2 attenuates the output to an EIRP of roughly 50 mW by absorbing most of the RF energy. If you need more range, you can simply connect an external antenna.

UHF Version Measurements
All measurements in this section apply to the UHF version. VHF measurements follow in the section below.
Sensitivity Measurements
The 12 dB SINAD sensitivity was determined using a 1 kHz tone FM-modulated at a 2.5 kHz deviation and injected into the receiver. This provides an accurate representation of real-world listening performance, fully aligned with industry-standard SINAD measurement procedures.
Compliance 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.
These measurements reflect the hardware platform used for this refurbished product line. Each refurbished unit is checked again before shipment.

Compliance Measurements
All measurements conducted with a calibrated Vector Network Analyzer (VNA) and 36 dB attenuator. Worst-case harmonic: −53.07 dBc (2nd harmonic), comfortably exceeding ETSI EN 300 220 CE RED requirements. This provides an extra safety margin of over 10 dB.
The spectrum confirms excellent spurious emission suppression and clean transmission within 12.5 kHz bandwidth. Compared to leading brands (Kenwood, Icom, Yaesu), our module delivers equal or superior spectral purity, placing it in the same performance league as established commercial radios.

Mini-FAQ
- What does refurbished mean here? — These are returned, replacement-cycle, or repaired units that have been checked, repaired where needed, and tested again before resale.
- Is it the same as the new model? — It is the same core Analog HotSpot platform with the same intended functionality and compatibility, but sold as refurbished because it was previously used, returned, or repaired.
- Why is it cheaper? — Because it is not sold as factory-new. Refurbished stock may show minor signs of prior handling or repair, so pricing is lower.
- Is it CE certified? — Yes. The hardware meets CE RED requirements and the certificate is available above.
- Which bands are supported? — UHF 70 cm (400–480 MHz) or VHF 2 m (134–174 MHz).
- Can it act as a hotspot? — Yes. Fully compatible with EchoLink and SVXLink.
- Digital networks? — Via AnalogBridge (DVSwitch): BrandMeister, OpenDMR, Fusion, etc.
- Output power? — ~28 dBm (~500 mW).
- Sensitivity? — UHF: −109 dBm / VHF: −104 dBm @ 12 dB SINAD.
- What antenna is included? — A terminated 50 Ω indoor miniature antenna. Complementary antennas are available below for extended coverage.
