Real time space weather from NOAA and WWV. GOES solar x-ray imaging of solar flares, coronal mass ejections and other phenomena that affects space weather. WWV's Geophysical Alert Message provides the most recent solar data including solar flux, A-index, K-index and storms.

 

Grid square locator computes the extended Maidenhead coordinate of a given latitude and longitude. The location data may be entered manually or can be retrieved from the phone if available.

Bing maps feature shows where you are and restricted operating zones - line A, C, and the National Radio Quiet Zone.

Dial up and decode standard IEC 60062 resistor color markings quickly and accurately.

Band plans from 160 meters through UHF, bandwidth cheat sheet for each commonly used mode, and common calling frequencies.

 

Dipole calculator gives an angle-adjusted length at the desired center frequency. The the final dipole length can be tuned by measuring and entering the frequency at which the SWR is minimized.

 

RF exposure evaluation tool is modeled after FCC OET 65 Supplement B. Step 1 is the initial determination.

 

Step 2 performs the RF routine evaluation process with a few simple input parameters.

When done, you can email the completed form and save it or print it out for your station records.

Two tone audio generator for adjusting your SSB rig.

Does anybody really know what time it is? Does anybody really care? The FCC does! Don't forget to ID your station every 10 minutes.

Maximum Usable Frequency and Maximum Usable Angle helps you get the most out of your rig based on atmospheric conditions.
