FreqFinder calculates the intermodulation products of user entered transmitter channels and then suggests options of channels that will be compatible with user transmitters already in use.
Recommended for use with 12-24 transmitter systems depending on the processing power of your device and the spread of your transmitters.
US Customers: TVDB in-app purchase now available. Accesses the FCC database for local TV broadcast towers and estimates the field strength at your location for better channel selection.
Change Audio Level, Frequency, Sleep mode, and Lock mode by playing a tone through an attached microphone.
Control transmit Power on SM transmitters with firmware version 4.0 or higher.
Safe - "Hold Button To Activate" prevents accidental changing of settings
Presets - save presets to quickly reference the settings on all of your transmitters
Volume Control - hear the loudness of the tone before activating it
*SM Transmitters must be configured to accept remote control. Hold the down button while turning the transmitter on and select "rc on". The original SM requires firmware version 1.5 (released 12/05) to respond to the remote. The firmware version number appears upon turning on the unit. SMa, SMQV and SMV models all support remote control.

This small App allows the user to easily do Ohm's law calculations to calculate Voltage, Current and Resistance. It also (optionally) calculates the associated Power dissipation value.
The user enters any two known values (V, I, R or P) and clicks the CALCULATE button to work out the missing values.
The user selects the proper units for the values entered and the calculator presents the proper units for the results.
For clarity values entered by the user are shown in Yellow and calculated results are shown in Green.
Any of the many uses of Ohms Law will benefit from this easy but powerful calculator.
E.g. Anyone designing electronic circuits must ensure that the power dissipated in the components is within the rating for that component, otherwise early component failure will be the result. This app helps the designer identify whether any resistors used will be overheated and helps the designer to work out a solution if they are.
E.g. Work out the current draw for your electric heater by entering its power rating and voltage.

PLEASE NOTE: Calculations based on correlated vs uncorrelated levels yield very different results. If you see an unexpected result, please verify the uncorrelated/correlated setting of this app first !
This tools helps to add and subtract an arbitrary number of power levels expressed in units of dBm and watt.
This tools helps to add and subtract correlated and uncorrelated voltage levels.
This tool calculates for an entry using a unit such as dBm, dBW, mW, W, mV, V, dBV, dBµV and dBu the corresponding values for all other units, for individual impedance values.
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.
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.
