Repeater Timeout Project Kit Launched

Regular users of amateur radio repeaters will know that they need to watch out for the ‘timeout’ – the moment that the repeater can cut off a conversation in mid-stream if it goes beyond a pre-defined time limit.

A new project kit, designed by Essex Ham member Andrew M0ONH, neatly solves the problem of alerting you before you hit the crucial timeout moment.

The kit was developed following discussions around Essex Ham’s Monday Night Net, where ‘overs’  are limited to two minutes. The Repeater Timeout Kit makes use of an  Arduino Nano board and some basic components to detect local RF when the transmitter is switched on, and provides a visual and audible warning when the timeout is approaching and has been exceeded.

We’ve put together a short video of the kit in action:

The kit is easy to construct and supplied with full instructions. It makes for an ideal beginner’s project, and serves a valuable need for repeater users. Potentially, it could also be a handy kit for use as a club construction project or at a buildathon.

The Repeater Timeout Kit is the first kit being offered by new online store HAMtronics.uk. which launched at the Langdon Hills Progression Night in January 2019. As well as being available online, the kit will be available at Suffolk RED on the 30th of January, and the Canvey Rally on Sunday the 3rd of February.

The kit is available for £10, plus UK postage, at www.hamtronics.uk.
