Ham Radio Reference

Great reference app for my of only 4 that I put on my new iPhone...I have tons of other Amateur Radio related apps on my iPad but this one was one of the few I like to always have at hand.

Installed it on my iPhone (ios 10)...when I first opened it up it said that the app needs to be updated for future iOS upgrades else it may cease to work...let us hope that happens...

thanks, 73s


Update Me!!

I use this app all the time for looking at band privileges and band plans. I would love to see an update to support the larger screen on the iPhone 6.

This is one of the two apps I use the most for Amateur Radio. I would be lost without it.

Missing crucial calculations

Nice app concept useful as a study reference for license tests. However, seriously lacking in almost all calculations needed for the US ham license tests - resonance, reactance, Q, R/C time constants, winding / turns ratio, modulation index, intermodulation, deviation, virtually no AC calculations such as peak, RMS, power factor, no antenna calculations. It would be far more useful with these items added.
