DX Cluster V1.0 for Android
DX Cluster is a DX cluster client for Android.
- Real time DX spots
- Different band and mode filters
- A country filter for spotter or the spots
- Prefix or callsign alarms
This app is intended to use by ham radio operators only. You need a ham radio callsign to log into the DX cluster!
At the first launch of DX Cluster you are required to enter your ham radio callsign and your name. This information will be used to log into the DX Cluster node. You also need to select the cluster callsign you want to connect to. DX cluster supports only AR-Clusters at this time. If your home node runs AR-Cluster but is not included in the list please email me at firstname.lastname@example.org and I will include it in the next version.
The spot list window shows the last 30 spots and gets updated as soon as a new spot arrives. Each row has the following fields: DX spot, frequency, time (in UTC), spotter and message (in case the spotter entered one) .
Below the list the last WWV data is shown. The values are as followed: solar flux, A-index, K-index, and a storm message.
The table on the bottom shows the ative filters for bands and modes. Green for filter on and gray for filter off.
The incoming spots can be filtered by band and mode. The filter frequencies are:
The group items are as followed:
DX spots can be filtered by Prefix for either the spot or spotter. If spotter is choosen only spots originated in the prefix entered will be displayed. If DX is choosen only spots with the spot prefix entered will be displayed. One or more prefixes can be entered but must be seperated by commas.
Example: Choose “Spotter” and “k,ve” and only spots originated in the USA and Canada will be displayed. Choose “DX” and “dl” and only spots in Germany will be displayed.
If vibrate on new spot is checked the phone vibrates on every spot which gets through the filters. If sound on new spot is checked the phone plays a notification sound on every spot which gets trough the filter. It can be used to check for a band opening. For example set country filter to “Spotter” and enter “k,ve” and set the band filter to “6m”. The phone vibrates for every spot on 6m which originates in the USA or Canada.
The alarm function will check the filtered spots for prefixes or callsigns and play an alarm ring tone. One or more callsigns or prefixes can be entered but must be seperated by commas. If you type “dl” in the field the call signs “dl8dbt” or “dl5dk” will ring an alarm but not callsigns like “n5dl” or “zs6udl”.
