ATU-100 Mini Antenna Tuner
ATU-100 Mini Antenna Tuner:
There are several variations on this tuner making the rounds. They've got an internal lithium battery with a
USB-micro on the front for recharging. It uses latching relays to hold its tune without continuously expending
power. Once tuned, it can be turned off until the tune needs to be adjusted. It's compact and light, great
for mobile use (camping?) and field events like Parks on the Air.
At boot-up it displays N7DDC, but that may just be the person that wrote the firmware. It looks like he's made
the software open-source, which explains why there are so many physical variations being sold.
One listing shows the tuner on a table in front of a tent. The scale's all wrong, the tuner looks HUGE and if
you zoom in, the AI image generator decided to plug in two cables on the left side of the tuner.
