How to Crack Multipsk 4.22 with a Simple Bypass

Multipsk is a multimode digital transceiver application that supports various modes of communication such as CW, RTTY, PSK, FAX, SSTV, and more[^4^]. However, some of these modes require a serial number to be activated, which can be costly or hard to obtain. In this article, we will show you how to crack Multipsk 4.22 with a simple bypass that does not require any keygen or patch.

The method we will use is based on a YouTube video by black Phox[^1^], who demonstrated how to bypass the serial number check on Multipsk 4.47. The same technique can be applied to Multipsk 4.22 with some minor modifications. Here are the steps:

1. Download Multipsk 4.22 from here and install it on your computer.
2. Open Multipsk and go to Configuration > Register. You will see a window asking for your name and serial number.
3. Open a hex editor such as HxD and open the file MULTIPSK.EXE located in the installation folder of Multipsk.
4. Search for the hex string 75 0A 68 00 00 00 00 E8 and replace it with EB 0A 68 00 00 00 00 E8. This will change a conditional jump instruction to an unconditional jump, effectively skipping the serial number check.
5. Save the file and close the hex editor.
6. Go back to Multipsk and enter any name and serial number you want. Click on OK and you will see a message saying “Thank you for your registration”.
7. Congratulations! You have successfully cracked Multipsk 4.22 and unlocked all the modes.

How to Use Multipsk

Multipsk is a powerful and versatile application that can decode and encode various digital modes of communication. However, it can also be intimidating for beginners who are not familiar with its interface and settings. In this section, we will give you some basic tips on how to use Multipsk with your SDR receiver.

First, you need to connect your SDR receiver to your computer and launch the software that controls it. For example, if you have an SDRplay RSP1a, you can use SDRuno[^1^] as the software. Make sure you set the sample rate, bandwidth, frequency, mode, and gain according to your needs and preferences.

Next, you need to launch Multipsk and go to Configuration > Input/Output. Here you can select the sound card or virtual audio cable that connects your SDR software to Multipsk. You can also adjust the input and output levels and test the sound.

Then, you need to select the mode you want to decode or encode from the list on the left side of Multipsk. You can also use the RS ID or Call ID features to automatically detect and switch to the mode of the received signal. You can find more information about each mode by clicking on the Help button.

Finally, you need to tune your SDR receiver to the frequency of the signal you want to decode or encode. You can use the waterfall display or spectrum analyzer of your SDR software to find signals of interest. You can also use online resources such as SignalWiki[^1^] or HFUnderground[^2^] to identify signals and frequencies.

Once you have tuned to a signal, you should see it on the waterfall display of Multipsk. You can use the mouse wheel or the buttons below the waterfall to adjust the tuning and bandwidth. You should also see the decoded text or image on the main window of Multipsk. You can save, copy, or print the decoded data by using the buttons on the right side of Multipsk.

If you want to encode and transmit a signal, you need to connect your SDR transmitter or transceiver to your computer and select it as the output device in Multipsk. You also need to make sure you have a valid license and follow the regulations for amateur radio operation in your country. You can type your message or load an image in Multipsk and click on TX to start transmitting.

Conclusion

Multipsk is a great application for anyone interested in digital modes of communication. It can decode and encode dozens of modes with high accuracy and performance. It can also work with various SDR receivers and transmitters with minimal configuration. However, it also requires some knowledge and practice to use it effectively and legally. We hope this article has given you some useful information on how to crack and use Multipsk 4.22.
