## ICluster - DX Description
THE ORIGINAL DX-CLUSTER APP
iCluster is an iPhone and iPad App for HAMs, SWLs (Short wave radio listeners) or for everybody who want’s to know, what’s going on on the amateur radio frequencies.

This App is connecting the so called international DX-Cluster database in realtime. The results are analyzed and displayed in an easy to read overview.

The content can be filtered by frequency (e.g. 80m, 40m etc.) or mode (CW = Morse, Beacon or digital modes), Call Prefix, ITU/CQ Zone, Country and many more.

Calls (the callsign of the operators) will be decoded automatically by the App. This allows even inexperienced users to know the countries of the operators.

iCluster is an ideal tool for amateur radio operators for field days or contests. But also unlicensed users can use iCluster to find out the frequencies for their shortwave scanner or short wave radio receiver.

MAIN FEATURES:

■ Real time DX-Cluster database
■ Several pre-defined Cluster Servers
■ Easy to add your own Server (e.g. CW-Skimmer)
■ Several Filter and Filter combinations
■ Several Alarm settings
■ QRZ.com (Database!) lookup
■ QRZ.com website lookup
■ HamQTH lookup
■ Display whole cluster on a Map (Globe)
■ Display single Spot on a Map (Globe)
■ Shows distance and bearing from own location
■ iCloud Synchronization
■ UTC Clock
■ No HAM license or registering required

Take a look to the manual to find out more:



This App exists since the App Store Exists as this was my first App. It has been continuously improved and re-written several times and is now available as Version 12, written in Swift 5. 

It's interesting to see how many other bad copies of my App are available on the App Store. If there is another DX-Cluster App, offering features my App is missing, just let me know.

## ICluster - DX Reviews in Vereinigte Staaten

### *---- "Poor software support for telnet password authentication"
This software lacks the reliability and ability for a secured login to a server with a password.  The developer seems not to understand the gravity of internet security and refuses to work with me as a fellow customer and developer to solve any issues. Just says “oh, it works for me.”  

AVOID THIS SOFTWARE!
-- Atgtechs, 2021-03-25

### ***-- "Stopped working"
Perhaps since the most recent update, this program has stopped working. Pinwheels, crashes, locks up. Had been great in past.
-- Naturegeezer, 2015-12-24

### ****- "iCluster works on iPad"
iCluster works on my iPad.  When in settings, I need to be in portrait view to see all the buttons.  Then switch back to landscape or stay with portrait view if you prefer.
-- KT7789, 2015-03-06

### **--- "Locks up my iPad"
Locks up the iPad most times I use it.
-- Dave1138, 2015-01-22

### **--- "Stopped working today"
Can't find server & will not allow another server to be used.
-- darthfadar, 2014-11-24

### ****- "Great mobile ham App"
This is a must have App for mobile Ham.  The new filtering feature allows you to only see spots from spotters in your region, as well as a bunch of other options.  I was looking for that feature in a cluster. Qrz integration is cool too. 

Only wish there was a logging program integrated   That way I wouldn't have to switch back and forth between Apps.
-- VetteSteve, 2014-03-10

### ***** "Vast improvement"
Latest version really rocks! Filters much easier to set up and they work well. Thanks for the improvements!
-- KC7ES, 2013-11-27

### *---- "ICluster - The DX -Cluster Database"
Loved the app until the May 3 update. I do not like having to the spotting of all bands at the same time on the screen. Can't select jus one band anymore. Dumped the app.
-- Martin In Ca, 2013-05-04

### ***-- "Filters"
Zone filter for spotter not working on iPad for me. Call area works but all countries come through.
-- Sixeye of SD, 2012-09-27

### ***** "Works great!"
As advertised! Works fine for me, no crashes, adequate filtering.
-- Rosea1, 2012-03-07

### ****- "Near Excellent"
I wish I had known about this app long ago. As a 100% DX chaser this is a real time saver. I can't wait until being able to filter to CW Only mode along with selection of band.
-- Bowguy#1, 2011-12-17

### *---- "Inoperable"
Won't even run, shuts down immediately.
-- AJ4WC, 2011-12-05

### ***** "Great!"
Well worth the price! Made quite a few new DXCC countries with it! Thanks!

### ***** "Awesome"
Very easy to use and very helpful.
-- AZ2010AZ, 2011-04-16

### ****- "Works well"
Only wish it had a filter for "HF Phone Only"
-- dajackman, 2011-03-23

### ****- "Good app!"
Easy to use and set up. Great to be able to check DX Cluster spots away from the shack on mobile device.
Some improvement in filtering options would be good. Allow change of band selection to be done easier than having to drill into Settings menus. Happy with it otherwise. Hoping for more Ham Radio iApps to come along.  73.
-- CWR0747, 2011-02-28

### ****- "Good App"
Good, but not yet great.  Would like to see more in the way of mode filters. All modes or CW is too limiting. At minimum: All, CW, Phone, Digital.
-- KI0DN, 2010-12-31

### ****- "A DXer's BEST FRIEND"
For DXer's on the move, this app is great! All of the critical review issues seem to have been fixed, and now US spots are included. You can filter just about anything now. Working new ones with the help of this great app.
-- Lawyer in Atlanta, 2010-12-26

### **--- "Useless here"
No spotting info from us spotters.  Should have the ability to pick cluster server to solve this problem.
-- Linxdev, 2010-09-14

### *---- "Useless in the US"
Needs the ability to pick a dx cluster; the hardcoded cluster has only European reports.
-- notto99999, 2010-08-02
