Turning on the analyzer.

The Stick 230 analyzer can be turned on in several ways:
– by pressing the kansel1 key.
– when connecting the analyzer to a PC via a USB cable (the analyzer will turn on automatically).
– by long-pressing one of the keys : minus plyus levo1 vpravo
Important! At the same time, the analyzer will turn on and activate the measurement mode to which the pressed key corresponds.

You can turn off the analyzer from any mode by long pressing the kansel1 key.

When the analyzer is turned off, its screen does not become blank. The screen always displays the following information:


Main menu.

After turning on the analyzer, using the kansel1 key a screen with the main menu of the analyzer is available for the user.
In addition to service information, at the top of the screen (battery charge, the indication of connection to a PC, charger, Bluetooth connection), the screen displays 4 main measuring functions of the analyzer:


minus Singe   Multé plyus

levo1 HAM    Free vpravo

The Singe and Multé functions display the measurement result as numbers, while the HAM and Free functions display the measurement results as numbers and charts.
When you press ok  in the Main Menu, 5 information screens will be available.
The first four screen will briefly talk about the main measuring functions of the analyzer (Single, Multé, HAM, Free). By pressing the ok key, you can switch to the corresponding measurement mode.
On the fifth screen, when you press the ok key, you will enter the Settings menu.


The Single mode.

Single is a measurement of all parameters. The mode is started by pressing the  minus  key.
After pressing the key, the measurement will start automatically. This is indicated by a flashing antenna icon located at the top of the screen. You can stop the measurement by pressing kansel1 once. You can resume the measurement by pressing  ok once.

In Single mode, the analyzer has 5 screens with information.
The first screen displays:

  • working frequency
  • SWR value
  • return loss value

The second screen displays:

  • working frequency
  • |Z| value
  • value of active (R) and reactive (X) resistance (taking into account the sign) for the series mode

The third screen displays:

  • working frequency
  • |Z| value
  • inductance (L) and capacitance (C) value for series mode

Important! Sometimes inductance or capacitance values are displayed with a minus sign. It would seem to be contrary to the laws of physics. But no, in Rig Expert analyzers, the minus sign next to the value indicates how much inductance or capacitance you need to add to the circuit in order to compensate for the reactive component of the impedance.
On the fourth screen are displayed:

  • working frequency
  • magnitude
  • value of active (R) and reactive (X) resistance (taking into account the sign) for parallel mode

The fifth screen displays:

  • working frequency
  • phase value
  • inductance (L) and capacitance (C) value for parallel mode

Screens switch among themselves by pressing levo1  vpravo keys.
There are two ways to change the value of the operating frequency:

  • keystrokes minus and plyus A single press changes the frequency value minimally. If you press and hold the keys, the frequency will change continuously with an accelerated step.
  • pressing and holding the ok  key for 2 seconds. After that, an information window will appear on the analyzer screen. Press ok key again. A window will appear on the analyzer screen with the setting of the operating frequency. The levo1 vpravo keys select the cursor position to change units, tens, hundreds, thousands of kilohertz, and the minus plyus keys change the value.

A single press of the ok key saves the change and returns to Single mode.
A single press of the kansel1 key returns to Single mode without saving changes.
The help menu is accessible by pressing and holding the ok key and then selecting the Help mode with the levo1 vpravo keys.

Multé mode.

Multé is a new mode, in which you can quickly assess how well your antenna works on different HAM bands. The result is displayed as stars. The smaller the SWR of the antenna in the range, the more stars.
Table of the dependence of the number of stars on the SWR:

5gold_star   –   SWR from 1.0 to 1.1

4gold_star   –   SWR from 1.1 to 1.15

3gold_star   –   SWR from 1.15 to 1.3

2gold_star   –   SWR from  1.3 to 1.7

1gold_star   –   SWR from 1.7 to 3.0

The SWR over 3 analyzer in Multé mode ignores.

If, after scanning, the analyzer did not find a single resonance, then this means that either your antenna has a minimum SWR of more than 3, or the antenna or coaxial cable is damaged.


Restarting this mode is possible by pressing any key except kansel1 key.
After successful measurement in Multé mode, the following information will be displayed on the analyzer screen:

  • band
  • number of stars (out of 5)
  • minimum value of SWR and the frequency at which this value was found

If there are more than one results detected by the analyzer, then the screens are switched using the levo1 vpravo keys.
When you press the minus plyus keys on one of the results screens, the analyzer switches to HAM mode on the same band.

Multe strelka HAM

A long press of the ok key will bring up the Help menu.

HAM mode.

This mode allows you to measure and display the SWR antenna chart on the analyzer screen on one of the fixed HAM radio bands such as:

2.2 km, 630 m, 160 m, 80 m, 60 m, 40 m, 30 m, 20 m, 17 m, 15 m, 12 m, 11 m, 10 m, 6 m, 2 m.

Enabling this mode is possible either from the main menu by pressing the levo1  key or when the analyzer is off by a long press of the same key.  The measurement will be performed automatically in the range that was used in the previous measurement.

To repeat the measurement, press ok  once. To measure in a cycle, press the ok key two times at short intervals. A long press of the ok  key will bring up the Help window.

 You can change the measuring range using the levo1 vpravo  keys.


In HAM mode, the SWR icon and the range over which the measurement is carried out are displayed at the top of the screen.

In the center of the screen, a chart of the SWR values for the range is displayed.

The value of the minimum SWR found and the frequency at which this value was found are displayed at the bottom of the screen.

Important! To the left and right of the graph are two vertical stripes. They indicate going out of range. Sometimes the resonance of the antenna may be out of range, but very close to the beginning or end. In such cases, the analyzer will determine the resonance beyond the limits of the ranges.

When you press the minus or plyus keys the analyzer switches to Free mode with the center frequency of measurement corresponding to the center frequency of the selected range:

17m1 strelka 17m2

You can exit the mode in the main menu by briefly pressing the kansel1 key.

Free mode.

This is a classic SWR measurement mode with plotting in a user-defined frequency band.

This mode is useful for survey measurement of the antenna in a wide frequency range or for measuring the SWR in a very narrow predetermined area.

In Free mode, the following is displayed on the analyzer screen:


  • at the top of the screen: the value of the center frequency of the measurement and the width of the measurement band.
  • in the middle of the screen: SWR chart
  • at the bottom of the screen: the SWR value under the marker (solid vertical line) and the minimum of the SWR found (dashed vertical line).


There are two ways to set the center of the measurement frequency:

  • levo1 vpravo keys. Pressing the key once will change the frequency discretely to a certain value. Pressing and holding the key will cause an accelerated continuous change in frequency.
  • long press ok  After press, a window will be available with a choice of setting the center frequency, exit or calling Help. Press  ok  briefly and enter the frequency setting menu.

The levo1 vpravo keys select the cursor position to change units, tens, hundreds, thousands of kilohertz, and the minus plyus keys change the value.
Setting the measurement bandwidth by pressing the minus plyus keys.
The minimum bandwidth is 10 kHz.
A quick double press of the ok key will cause a measurement in a loop. To stop click kansel1 key.
To exit the mode, briefly press kansel1 key.

Settings menu.

In order to get to the settings menu, in the Main menu, press and hold the ok key.

After that, the information window will be available:


Pressing the  ok key will take the analyzer to the Settings menu. Pressing the kansel1 key will return the analyzer to the Main menu.

Change of settings screens is carried out with levo1  vpravo keys and change of parameters with minus  plyus keys.

There are currently 7 basic settings available in the Stick 230 analyzer:

  1. Turn on/off Bluetooth (enabled by default). If you do not use the Bluetooth connection of the analyzer with the smartphone, turn off this function. This will save battery power.
  2. Enable screen inversion (disabled by default).
  3. Analyzer automatic shutdown time (battery saving mode). Available values: never, 5 minutes, 10 minutes, 30 minutes, 60 minutes, 90 minutes. Default: 5 minutes.
  4. Choosing ITU region. The default is 1 region. The choice of region affects the boundaries of predefined ranges. The width of most ranges in each region is different.
  5. Band search. This setting affects the speed worked of the Multé function. There are two meanings: Normal and Deep. In Normal mode, the Multe function is fast, but there is a chance of missing the narrow resonance of the antenna or inaccurate determination of resonance frequency. In Deep mode, the measurement speed increases, but the possibility of mistake is minimized.
  6. System Z0. Choosing a system impedance value. Available values: 12.5 Ohm, 25 Ohm, 28 Ohm, 37 Ohm, 50 Ohm, 75 Ohm, 100 Ohm, 150 Ohm, 200 Ohm, 300 Ohm, 450 Ohm, 600 Ohm.  Default: 50 Ohm. This setting is needed in cases where, for example, when measuring, a broadband transformer with a transformation ratio of 1: 9 is used. In this case, the impedance at the transformer output will be 450 Ohms and for the correct readings of the analyzer, it is necessary to set the system impedance equal to 450 Ohms.
  7. Factory Reset. Reset all analyzer settings to factory defaults. To reset, press and hold the  ok  key.

Settings are saved automatically when they are changed.
To exit the Settings menu, press the  kansel1  or  ok  keys.

AntScope2 and AntScope for Android

Stick 230 analyzer can work with AntScope2 and AntScope for Android.

AntScope2 works with personal computers and laptops running operating systems Microsoft Windows, macOS, Linux Ubuntu.

The latest versions of the software for various operating systems can be downloaded here:

Important! The Stick 230 analyzer does not work with the first version of AntScope.

To work with AntScope2 the analyzer does not require the installation of any drivers. Just connect the analyzer to the PC via the USB cable and run the AntScope2 program (the program must be downloaded and installed first). The program should automatically recognize the analyzer and prepare for work.

At the same time, the following information will be displayed in the upper part of the program window:


If the analyzer model does not appear, then this means that the program could not recognize the analyzer. Try reconnecting the analyzer, closing and reopening the program, used a different USB cable.

Important! Using a Bluetooth connection, Stick 230 analyzer operation with AntScope2 is currently not possible. This is due to limited support for the Bluetooth Low Energy protocol used in the analyzer in Windows operating systems.

The Stick 230 analyzer, together with AntScope for Android, works with smartphones and tablets running Android version 6 and higher.

You can download AntScope for Android directly on Google Play

When you connect the analyzer to a smartphone with AntScope for Android, you will see the following information:

AntScope for Android

The window displays the following information:

  • analyzer model
  • serial number
  • MAC address
  • Bluetooth version

If the analyzer is successfully connected to the program, the BLE icon will appear at the top of the analyzer screen next to the Bluetooth icon:

If the program could not detect the analyzer, check whether Bluetooth is enabled in the analyzer (1 mode in the Settings menu) and whether Bluetooth is enabled on your smartphone/tablet.

Charging the analyzer.

The Stick 230 analyzer is powered by a 18650 Li-ion battery. The analyzer comes with a 2800 mAh battery.

The analyzer can be charged from a PC. According to the specification, when connecting the analyzer to the USB 2.0 connector, the maximum charge current is 0.5 A. When connecting the analyzer to the USB 3.0 standard connector, the maximum charge current is 0.9 A.

The analyzer for charging can be connected to any charger (for phones/tablets) with an output voltage of 5 volts and a current of at least 0.5 A.

The maximum charge current of the analyzer is 1 A.

The time for a full charge of a battery with a capacity of 2800 mAh (from 0 to 100%) is about 3 hours (when using a charger).

During charging, the bottom of the analyzer near the USB connector may become slightly warm. This is not a malfunction.

During charging in the off state, the lightning icon is displayed on the analyzer screen.

During charging, when the analyzer is on, the CHG icon will be displayed at the top of the screen. If the charge occurs with a current of 1 A, then, in this case, the FAST icon is additionally displayed. For example, a screenshot of the screen of the analyzer charged from the charger:


The analyzer battery can also be charged separately. For this, it is necessary to remove it from the analyzer by unscrewing the two screws of the battery cover and place it in an external charger.

The Stick 230 analyzer is protected against battery polarity reversal. An incorrectly installed battery will not cause damage to the analyzer, and when the charger is connected, the analyzer will display an error message on the screen.

Important! Do not use other types of batteries!  Do not use chargers with a voltage of more than 5 volts! This may damage the analyzer.
