AIOC (All-in-one-Cable)

The AIOC is a small adapter with a USB-C connector that enumerates itself as a sound-card (e.g. for APRS purposes), a virtual tty (“COM Port”) for programming and asserting the PTT (Push-To-Talk) as well as a CM108 compatible HID endpoint for CM108-style PTT (new in firmware version 1.2.0).

The AIOC is Open-Source Hardware designed by Simon Küppers.

Discovery Drive for the Discovery Dish

There's an interesting crowdfunding project on https://www.crowdsupply.com for:

[...] a low-cost, turnkey, fully weatherproof, high-quality automatic Az/El (azimuth/elevation) antenna rotator designed for use with Discovery Dish and other antennas of similar size and weight, such as Yagi and Wi-Fi grid antennas.

A motorized rotator allows you to use a satellite dish or directional antenna to track and receive signals from polar orbiting satellites, which quickly move across the sky. It also lets you switch swiftly between geostationary satellites without manually realigning the dish. It’s also very easy to set up—no fiddling with expensive, separate controllers! Just connect Discovery Drive to 12V and Wi-Fi (or USB serial) and go!

It's priced at $699 US and funding ends on Apr 23, 2026 at 04:59 PM PDT. That could be an interesting solution (though probably overkill) for an AREDN dish.

Getting Started with FreeDV

A few months ago, I posted about FreeDV without knowing much about it. A few weeks ago, I found this comprehensive guide by VU3DXR.

I'm gonna put this on my ham radio to-do list...

TX-500MP and LiNK500MP TNC

The TX-500MP by Lab599 is a portable / handheld HF transceiver. Recently, DiY599, an after market company, created the LiNK500MP TNC, which fits on top of the radio and adds digital and CAT capability to the radio wirelessly.
