Read full description

The Morse Decoder AI is an application for decoding Morse code signals using artificial intelligence. The application is designed for use by amateur radio enthusiasts for educational purposes. The Morse decoder listens to the audio stream through the microphone or line input and, upon detecting Morse code signals, decodes them into text. The neural network of the application is trained to decode signals with a speed ranging from 10 to 40 words per minute within a frequency range of 200 Hz to 900 Hz. The application supports two modes of operation: direct (default) and tone filtering mode. In direct mode, the neural network will attempt to decipher Morse code signals in the audio range of 250 Hz to 900 Hz. This mode is suitable for confident reception of Morse code at levels of 7db-9db on the S-meter. The tone filtering mode is ideal for decoding Morse code from noisy weak signals in the presence of radio interference. The audio input signal is first filtered using band-pass filters before being passed to the neural network for decoding. This mode allows for the decoding of faint signals, but it requires the accurate specification of the signal's tone frequency. Each radio amateur selects their own CW tone frequency in the transceiver settings, and it is important to tune precisely to the carrier frequency using the ZIN/SPOT button in YAESU transceivers, or the AUTOTUNE button in ICOM transceivers. There are 3 band-pass filter options available: 25Hz, 50Hz, 150Hz. If you can accurately determine the CW signal tone frequency, using the 25Hz filter, you can decode very faint Morse code signals. The application offers two neural network options: A and B, which can be easily switched in the interface. Network A is recommended for use with stable signal transmission with a constant duration of dots and dashes, while network B is recommended when using a straight key, where the duration of dots and dashes may vary. You have the ability to switch between these networks in real time and observe how each network hears and decodes Morse code. It is important to monitor the level of the incoming audio signal, for which the application provides a sound level indicator. Ensure that the signal is not too quiet or too loud. It is recommended to maintain the signal around -7db, which is sufficient for decoding. Keep in mind that higher audio frequencies are quieter than lower frequencies. Additionally, the application provides various color themes, allowing radio enthusiasts to customize the appearance of the application for comfortable use.

Verdict

The call

The clearest difference is review sentiment: SDR at 84% against Morse Decoder AI's 11%. SDR also leads on rating (4.5 vs 2.0) and ratings volume (64 vs 4). Morse Decoder AI's advantage is price ($2.99 vs $44.99) and update cadence (weekly vs every 2 weeks). On ads, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

SDR costs $44.99 and Morse Decoder AI $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

SDR holds the better App Store score, 4.5 against 2.0. That said, the two scores are not equally well evidenced: SDR has 64 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 84% of SDR's written reviews are positive against 11% of Morse Decoder AI's.

UpkeepUpdate frequency

SDR ships an update every 2 weeks, Morse Decoder AI weekly. The most recent releases landed on October 11, 2026 and October 10, 2026 respectively.
