Pebble HF Accessories

Here are the accessories we know work or recommend to use with the Pebble HF. We'll keep adding to this list as time goes on.

Batteries

• INIU Power Bank USB-C PD 45W
• 12V USB-C PD cable to go with the battery — Short USB-C 12V PD Cable from DigiRig: Amazon or DigiRig
• 12V USB-C PD cable generic option that is cheaper

Speakers and Headphones

Note: Various speakers and headphones are not as compatible as some other radios, so you may have to test different ones. This list contains known working ones.

• AYL Powered Mini Speaker
• Earbuds — Amazon Basics

Antennas

• Any 20 meter resonant antenna should work
• EFHWs are widely available in the $30-60 range and easy to use
• The Just OK Mini 20m Antenna from HamRadioDuo does work, but we recommend only using it for convenience given that EFHWs, verticals, and dipoles will likely be higher performance

Audio Adapters (Sound Card) for Digital Modes

• USB Audio Adapter (recommended by hardware designer Barb)
• Sabrent USB Audio Adapter
• 2x short audio cables

Microphones for Voice

• Microphones designed for the QMX or uSDX should work
• Mic Mini on Etsy from XTennaAntennas
• G7UFO Mic is well tested and a good option for Europe but expensive shipping for the US

Dummy Load for Testing

• Dummy load for up to 10W
• Barb-o-Watt is a power meter and dummy load (contact Barb WB2CBA for purchasing options)
