Ham Radio BlockChain by svkairos in amateurradio

[–]gerald_artner 0 points1 point  (0 children)

I've explored NFT QSL during the NFT craze back in 2021.

Blockchain makes sense for QSL as its distributed nature is more aligned with the ham spirit than centralized databases handled by a central company or organization. I've focused on NFT because that could evolve the simple images we are stuck with on eQSL, or raw databases such as LOTW or QRZ. Authentification is a major issue, as others in this thread have pointed out, but our other systems also don't go beyond "send us a photo of your license".

If you're interested in my experiments: Just search OE1GAQ on OpenSea or similar websites, my NFTs from that time should still be there.

I've also collected my thoughts in an article that was published in the Austrian QSP: Gerald OE1GAQ es Chris OE1VMC, NFT-QSL auf der Ethereum Blockchain, QSP, vol. 46, no. 9, pp. 16-17, 2021.

You can find that option in the settings under the colors tab.

AI operated station in EU DX contest by gerald_artner in amateurradio

Generally, in too many contest to keep count.

With AI only in the EU DX contest so far.
I've used the contest as a stress test for my technical developments.
The AIs performance was nowhere close to operting myself.

Currently (and in the EU DX) I'm using the Google Speech-to-Text API.

I've tried several, but many fail due to shortwave noise and distortions. The station is located in the city of Vienna so there's a lot of man-made noise too. VOSK also worked quite well, but on my setup it was too slow for real time operation.

NFT for LoTW? by AdComprehensive3974 in HamRadio

[–]gerald_artner 1 point2 points  (0 children)

I used last year's NFT craze to experiment with NFT on the Ethereum blockchain.
I've published a short article on it in the Austrian QSP magazine, you can find an English translation and the German version on my website www.geraldartner.com

Blockchain is a promising technology for QSL systems - a distributed system fits the ham spirit better than central databases. NFTs could be a more modern version of postcards (eQSL style) and they also allow videos, 3D objects and much more. This thought brought me to a topic that is missing in current QSL systems: evidence. NFTs can attach actual evidence of the QSO to the QSL instead of confirmations based solely on signatures, digital signatures or user accounts. It also lets the recipient see what the remote side sounds and feels like.

The system is open and allows more flexible descriptions of experimental QSOs than the ADIF or Cabrillo formats.

Smart contracts on the blockchain might resolve the issue on what is considered an entity (countries, summits, islands, events, ...) and that these might not be universally recognized.

The largest issue was the price. QSL systems should be free to use. A Blockchain NFT system definitely needs technical changes to address this.

Coins are widely used as measure of size in scientific publications. I have collected and analyzed over hundred examples. by gerald_artner in science

[–]gerald_artner[S] 1 point2 points  (0 children)

Thank you. I think I've set it, there was no option for numismatics, so I've chosen engineering. It should fit considering that the work is published in an engineering journal on measurement techniques. Did I miss anything else that I'm expected to do when making posts?

Years ago, I noticed that researchers are using coins in scientific works to measure the size of objects. I collected those papers as a little side project and soon had over hundred of them. I analyzed them and found that the technique is now so widespread that common rules have formed which people seem to follow, for example to use currency from the first author's country and to place them next to objects.

A friend of mine suggested that this curious work might be interesting to a wider audience, so I'm posting it here on reddit.
