Off topic: AI and shortwave radio  View Printable Version 
Friday, November 17 2023

HCDX
( intro text here is also AI enhnaced )As you know, I have been exploring the use of artificial intelligence (AI) in various fields, including poetry and image creation, as well as personal assistance. During a recent test of a new chat application using GPT3.5, a renowned AI system, I asked how AI can aid in diagnosis. The following response was provided in parts.


Artificial Intelligence (AI) can enhance shortwave reception in several ways. Here are a few methods:
1. Noise reduction: Shortwave reception is often impacted by various forms of interference and noise, such as atmospheric noise, electrical interference, and fading. AI algorithms can be employed to analyze the received signals in real-time and apply advanced noise reduction techniques like spectral subtraction, wavelet denoising, or adaptive filtering to improve the signal quality.
2. Signal detection and demodulation: AI can assist in detecting and demodulating shortwave signals by using pattern recognition algorithms. AI models can be trained on a large dataset of known signal types, allowing them to recognize and classify different types of signals present in the received shortwave signals. This can help identify and extract valuable information from the received signals more accurately.
3. Automatic tuning: AI can be used to automatically tune shortwave receivers, selecting the best frequency and adjusting the receiver settings for optimal reception. Machine learning algorithms can analyze historical data, including time, location, and propagation conditions, to predict the optimal frequency and tuning parameters for a given time and location.
4. Adaptive beamforming: Shortwave reception can benefit from antenna arrays with adaptive beamforming capabilities. AI algorithms can analyze the received signals from multiple antenna elements and intelligently adjust the phased array pattern to enhance the desired signal and suppress interference or noise from other directions.
5. Propagation prediction: AI techniques can be leveraged to predict shortwave propagation conditions. By analyzing historical data, solar activity, weather patterns, and geographical factors, AI models can provide forecasts of the optimal frequency bands and signal paths for better reception.
6. Signal enhancement: AI can enhance the received shortwave signals by effectively reconstructing missing or distorted parts of the signal. Techniques like interpolation, super-resolution, or deep learning-based image/signal enhancement algorithms can help to reconstruct and restore weak or distorted shortwave signals, improving signal intelligibility.
It is important to note that implementation of AI-based shortwave reception enhancements would typically involve a combination of specialized hardware, software algorithms, and machine learning techniques.
7. Channel equalization: Shortwave signals can experience frequency-dependent fading due to multipath interference and other propagation effects. AI algorithms can be employed to estimate and compensate for these channel impairments through equalization techniques. By analyzing the received signals, AI models can adaptively adjust the equalization parameters to mitigate the effects of fading, resulting in improved reception quality.
8. Signal classification and prioritization: AI can be used to classify and prioritize different types of shortwave signals. By analyzing signal characteristics, such as modulation type, bandwidth, and frequency content, AI algorithms can identify and prioritize important signals over noise or interference. This can be particularly useful in scenarios where multiple signals are present simultaneously, allowing for automatic selection and prioritization of signal of interest.
9. Dynamic frequency hopping: Shortwave reception can be challenging due to changes in propagation conditions. AI can be utilized to dynamically select and adapt the frequency hopping patterns in real-time. By monitoring the quality of received signals and analyzing historical data, AI models can predict the most suitable frequencies to hop to, maximizing the chances of maintaining a strong and stable signal.
10. Intelligent antenna selection: Shortwave reception antennas can have different radiation patterns and characteristics. AI algorithms can analyze the received signal strength from different antennas and intelligently select the antenna with the best reception quality. This can be done by incorporating factors such as signal-to-noise ratio, interference levels, and directionality into the decision-making process.
11. Contextual information integration: AI can leverage contextual information like location, time, and user preferences to personalize shortwave reception. By considering factors such as known station schedules, preferred stations, local interference sources, and previous reception history, AI algorithms can adapt the reception parameters and settings to provide a more tailored and optimized shortwave experience.
12. Feedback-based optimization: AI can continuously learn and adapt to changing reception conditions through user feedback. By incorporating user ratings, preferences, and reception quality feedback, AI models can refine their algorithms and make more accurate predictions and adjustments for better shortwave reception.
It is worth noting that while AI-based enhancements can improve shortwave reception, they should be seen as complementary tools and should not replace the importance of using appropriate antennas, quality receivers, proper grounding, and other best practices for optimal shortwave reception.
Hope that this i will be a very  intriguing and fruitful topic here i  expecting your ideas.

re Urumqi, site at Hutubi, Changji Tian Shan, and Hongguangshan, some 34 / 32 kilometers apart distance.  View Printable Version

Glenn Hauser via groups.io kirjoitti 15.11.2023 klo 4.28:

WRTH 2023 dispenses with any sked info and lists all four not at

Urumqi, but "Changji"! Is that the same as Changzhi in gaisma.com?

But that's way off in east China near Beijing

Changji is at 43 58.5N 87 15E , 35 km east-southeast of the FS and MW

site, so clearly a separate site.

Best regards,

Mauno

Yes right,

and at CHN_Urumqi Hongguangshan

more 32 kilometers far easterly in 1960 to 2000 year old SW site gear:

now rebuilt HOUDING suburb area built up some railway main station

and other public buildings - in past 30 years.

Subject: Radio Erena?

Whatever became of them? Below the last mention of these transmissions herein.

They claim that they are still on 25 metres.
https://erena.org/%E1%88%98%E1%8B%B0%E1%89%A5-%E1%88%B8%E1%8A%BE%E1%88%AD%E1%89%B0%E1%89%B5-%E1%88%B0%E1%8A%95%E1%89%A0%E1%89%B5-12-%E1%88%95%E1%8B%B3%E1%88%AD-2023/

But at the known time from 1700 no such transmission to be found between 11400 and 12100 kHz anymore.
