More radio apps, then I'll leave this alone

Since I posted about Andoid phone apps for engineers last February, I noticed several others have picked up the thread and published articles as well. Good for you! I am glad that we can be of assistance here at Engineering Radio.

Radio World had a good article back in July on this subject.  I’m not going to link to it, just because.  I figured I’d add a few others that didn’t make the grade last go around, either because they didn’t exist, or I didn’t know about them.  I am limiting my choices to free apps for Android phones.

  1. Router passwords.  Often, very often in fact, the default password on any given router does not get changed when it is installed.  I found this app to be accurate and useful for speeding up various router tasks required in day to day radio engineering.  Things like opening ports for VNC, routing outside IP addresses to internal ones, etc.
  2. Navaile Electrical Calculator.  Great for National Electrical Code questions, wire sizes, breaker sizes, box fill, conduit fill, voltage drop, etc.
  3. RF & Microwave tool box.  Has handy calculators for filters, mismatch, return loss, etc, just in case those things need to be done by hand.
  4. GPS test.  Shows available GPS signals, gives time, location and accuracy in WGS84 datum.
  5. Shortwave Schedules.  Data base of shortwave schedules searchable by station, time, and frequency.
  6. Note pad.  Just what it says.
There are several other good ones, but these are the ones that I tend to use most often.

Axiom


A pessimist sees the glass as half empty. An optimist sees the glass as half full. The engineer sees the glass as twice the size it needs to be.

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
~1st amendment to the United States Constitution

Any society that would give up a little liberty to gain a little security will deserve neither and lose both.
~Benjamin Franklin

The individual has always had to struggle to keep from being overwhelmed by the tribe. To be your own man is hard business. If you try it, you will be lonely often, and sometimes frightened. But no price is too high to pay for the privilege of owning yourself.
~Rudyard Kipling

Everyone has the right to freedom of opinion and expression; this right includes the freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers
~Universal Declaration Of Human Rights, Article 19

...radio was discovered, and not invented, and that these frequencies and principles were always in existence long before man was aware of them. Therefore, no one owns them. They are there as free as sunlight, which is a higher frequency form of the same energy.
