Mircules DX Cluster vs RF Path

Find out which interesting DX HAM Radio Amateur operators are “on the air” on the amateur radio bands! Mircules DX Cluster is an iPhone and iPad app that shows the info found on the international DX Cluster. This cluster is widely used by radio amateurs and SWL enthusiasts to find the DX "treasures" on the bands. You can use one of the two web clusters we provide or choose a DXSpider (telnet) server from our list. You can also manually add your own DXSpider server address. This functionality is still a work in progress so let us know what you think and how we can improve it! ALL POPULAR AMATEUR BANDS ARE INCLUDED - MF / HF bands (10m, 12m, 15m, 17m, 20m, 30m, 40m, 60m, 80m, 160m) - VHF / UHF bands (70cm, 1.25m, 2m, 4m, 6m) SEE THE DX SPOTS IN A CLEAR LIST Mircules DX Cluster shows the last 50 DX spots on the selected band in a clear list. ALL THE INFO YOU NEED! Information that is shown per spot item in the main list is: - callsign of the spotted Radio Amateur - country of the spotted Radio Amateur - frequency where the person can be found - time and date of the spotting - any comments added to the spot by the spotter - CQ Zone, ITU Zone and DXCC info of both Radio Amateurs - callsign and other info of the person that did the spotting - QRZ.COM information of both Radio Amateurs - a map of the country / entity of both Radio Amateurs TOOLS AND INFO A list of HAM radio tools are available, like: - Azimuth calculator - Contest calendar - Grid calculator - ITU prefixes - Q-Codes - UTC clock etc...

RF Path provides propagation loss calculations for radio frequencies (RF) between 20 MHz and 20 GHz using either the Irregular Terrain model, Okumura-Hata model, COST-231 Hata Extension model, or the COST-231 Walfish-Ikegami model. The calculations are based on both electromagnetic theory and the statistical analysis of terrain characteristics to calculate the degradation of the RF wave as a function of distance and the variability of the RF wave with respect to time and space. The Irregular Terrain Model has two different prediction models. One is the Area Prediction mode which calculates propagation losses over an area where the exact terrain parameters are not known, but approximated using terrain roughness, environmental parameters and statistical parameters. The second is a point-to-point mode where specific latitude/longitude pair values are entered for both transmitter and receiver. Environmental parameters and statistical parameters are also used in this prediction mode. The results may be saved to iCloud, emailed, or posted to Facebook or Twitter. The results are in CSV format. In the Area Prediction mode a table along with a graph shows the path loss over the distance entered into the settings. The graph is viewed by rotating the device once the results table is shown. In the Point-To-Point Prediction mode a table along with a graph shows the path loss and elevation profile of the RF path.
