About this app

NKCCluster is a perfect radio-amateur (ham radio) DX cluster companion for when you're "up and about". With its small memory footprint, simple to navigate user interface, support for all popular DX cluster server software, quick and painless filtering, NKCCluster won't quite work you A Rare One all by itself but will definitely make your job much easier.

NKCCluster is compatible with DX Spider, AR-Cluster, DxNet, CC Cluster, and CLX nodes. It supports connecting to a user-defined DX cluster node, filtering DX spots per bands of interest, convenient lookup of stations' details on the Web, azimuth/bearing calculation, sending new DX spots to a selected cluster node and receiving cluster announcements.

Permissions this application requires are detailed on https://www.chonky.net/nkccluster/permissions-required.

Why don't you take a look at its Getting Started guide on https://www.chonky.net/nkccluster/getting-started and decide whether you'd like to give it a try?

Simple to set up and use. The app does seem to be quite heavy on the battery which is odd. I've tried this on a Samsung S6, a Pixel 2 and a Pixel 4 and all three exhibit the same increased battery use.... Not a major complaint as the app is still very good.

App refuses to update automatically, requires disconnecting and reconnecting to get latest spots. App often stops running with Android dialogue requesting to close or wait. Contacted the developer twice with no responses. As a hobby that is based essentially on communication, the developers lack thereof is far from impressive.

Sadly, despite closing the app, NKCluster continually runs in the background, draining your battery. Why on earth can't you Ask people when they close the app, whether they want it to continue running in the background or not? Uninstalled for this reason.

The application emphatically _does not_ run if you close it, there's a menu option for it called "Quit". If you only put it in the background it will happily continue running, which is the standard way Android apps are expected to behave.
