Problem solved. android-design.nl August 8, 2013

It is not (yet) optimized for tablets. android-design.nl April 22, 2013

Thank you for your brillante comment. Comprehensive features and easy to use Great toolbox at a bargain price. Thanks to developers for bringing up such a nice app

Love it, very handy, useful Nice comprehensive package, beats my boss microwave app for iPhone. Very impressed. I showed this app to colleagues at work and like out a lot. They wish that the app would be available for iPhone and Windows mobile system.

Insanely Useful This has just about everything I need for ham radio and EMC. Very stable so far and highly impressed.

Great for RF folks This is very useful in my circuit design work . It allows me to design or trade off parts of a design easily .

Great on DroidBionic ..didn't work on my old G1 Doesn't work on my old G1 phone, just forced app closure. Fantastic on my Bionic....well worth the coinage...excellent new additions.

This is by far the best RF app out there. The previous update made the app unusable and I emailed the developer and it was fixed the next day. Awesome

It just gets better and better Ive had this app for nearly a year now & it just keeps getting better and better. Almost every couple of weeks there is a new feature added for free!

A very useful and handy tool. Would like to see oscillator designs!

In gingerbread, in landscape mode, you cannot click on half the buttons, and you cannot scroll. Would give it 5 start review when this is fixed.

Works fine on my Galaxy S, although the interface is a bit clunky. I do however wish they'd add cascade toi to the noise figure screen as requested.

Use this regularly. Results all stack up. Emailed with suggestions for more tools. Incorporated in two days. Thanks Faust.

Great program that has everything. I use it all the time at the job. Developer adds new functions frequently.

## iCircuit

iCircuit is a fun and educational app for designing and experimenting with circuits. Its advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers.

You use it as you would any CAD program: you add elements, connect them together, and set their properties.

But iCircuit is unlike other CAD programs because it is always simulating. It's just like working with the real circuit. You do not stop to take a measurement or spend a lot of time configuring reports. Instead, you just play with the circuit as you normally would, with the power on!

There are over 30 elements you can use to build your circuits. The app has everything from simple resistors, to switches, to MOSFETS, to digital gates.

The app features a multimeter that you use to probe around the circuit to instantly read voltages and currents. If you want to see how a value changes over time, then you can add values to the built-in oscilloscope. The scope can simultaneously track many signals over time and features a touch interface to control the total time displayed and stacked and unstacked modes to easily compare signals.

Supported elements include:

* Signal generators, Voltage sources, Current sources, and Dependent sources

* Resistors, Capacitors, and Inductors

* Manual SPST/SPDT Switches, Push buttons, and Relays

* Diodes, BJ Transistors, and MOSFETs

* Speakers, Microphones, Buzzers, DC Motors, and LEDs

* ADCs, and DACs

* Logic gates: AND, OR, NAND, NOR, XOR

* JK and D Flip-flops

* 37 7400 series digital parts

* 7-segment display and driver

No matter your profession, we're sure you'll be amazed by iCircuit!

## Aviation RF Link

General

________________________________

________________________________

The program Aviation RF Link allows quick calculation of the forward link from a ground station to an aircraft. Based on the RF power of the ground station, the tool calculates the distance with a given field strength to be achieved at the aircraft antenna or calculates the field strength at a given power and distance to the aircraft.

The tool calculates the path loss based on line-of-sight (LOS) conditions and does not take into account multipath propagation on the ground.

In addition to the RF path, the tool calculates the radio horizon based on the given height of the aircraft and the ground station. If the calculated LOS is lower than the distance that can be achieved with the given radio conditions, this is indicated by a red dot on the LOS tab. In this case, the radio horizon is the limiting factor and not the RF link budget.

The line of sight is calculated in accordance with ICAO Annex 10 Vol. V.

The default for the antenna gain of 2.14 dBi corresponds to an omni directional antenna.

The default for the field strength of 75 uV/m corresponds to the ICAO recommendation for minimum reception at the aircraft antenna.

Quick start

________________________________

To start calculation, just select a row by touching it and change a specific value.

After touching the "Return" button, the dependent values are calculated automatically.

If any value other than distance is changed, the distance is recalculated. If distance is changed, the field strength is recalculated.

If you change a unit, the corresponding numerical values are converted. For example: 1 mW yields 0 dBm if the unit is changed from mW to dBm. Also conversion between feet and meters, and between nautical miles and kilometers is performed.

## RF circuits toolbox

## My toolbox

This is the pro version of the app with the same name. It has over 11 different functions that transforms your phone into a light yet reliable toolbox. Some of them use the sensors in your device and for this reason the results might be slightly different from one phone to another, depending on its quality.

The functions are as follows:

1) A calculator, useful for anyone that has to deal with numbers from time to time.

2) Flashlight - it turns your full-size screen into a torch! It also can flicker in different colors and at various speeds.

3) Bubble level - to measure angles, letting you selecting a reference (horizontal, vertical etc)

4) Alarm - a reliable alarm clock that wakes you up using a different ringtone every time, from the ones you have in your cellphone

5) Compass - feeling lost? Have a look and find where the North is. Or South, East or West for that matter.

6) Stopwatch - run, baby, run!

7) Recorder - audio records up to 60 minutes at a time.

8) Ruler - in inches and centimeters

9) Accelerator - shows how fast you device is going.

10) Countdown - baking something and want to be sure you won't forget about it? Use this timer!

11) Counter - perfect to count the sheep when you go to sleep.

It does not contain any kind of ads, is small, it goes directly to the external card and it works 100% offline. For more apps please check out our page. Have fun!
