Rex KE6MT (SOTA W6 Association Manager) kicked it off with: A friend of mine, George KJ6VU, has been talking with me and several others about the idea of an FM “Adventure Frequency.”  It would be for more than just SOTA – other *OTA’s could also use it. Years back you would see more hams wanted to participate in Emergency communications and events to both support the hobby and society as a whole. ham radio blogs category is a curation of 275 web resources on , Patriot Hills Antarctica - K2ARB, CQ CQ Nuevos Radioaficionados, CX3SS Gustavo. Hence the name “Adventure Frequency,” and not “SOTA Frequency.” It is really about hams operating portable in an outdoor setting. In particular, there is a mix of 15-kHz and 20-kHz channel spacings. THE VFOS 350 KHZ RANGE A big difference, though, is that the Yagi antenna has to be held and pointed. Should I do a POTA or SOTA Activation or Both. It’s just a beautiful way to spend time and make more friends. The illustration below gives an overview of the NN (green: operations, pink: data flowing through NN) and here follows a short description: Note that the model did not know anything about Morse code at the start. Dec.31.2020. We are not Ham Club, we are just a team that grown as a Licence's Ham Radio Operator that love Homebrews, experimental and More.. We create this blog to share about Hams News and more..

The National Calling Frequency (146.52) can be great for a few contacts sometimes, but other times it’s problematic either because it’s being hogged or because nobody’s listening. It's always interesting when I write, to see what feedback or help is out there. In ham radio terms the difference of 47 dB corresponds roughly eight S units - human ears & brain can still decode S2 level signals whereas conventional software based Morse decoders produce mostly gibberish. You will find here, in addition to amateur-radio-related news and events, posts about ham radio equipment such as: transceivers, receivers, antennas, software and more. I know I didn’t design the radio, but just the idea that I built it from a bag of parts, put it in an Altoids tin, hooked it up to a dipole antenna that I made from some speaker wire, and heard real, live CW is amazing! im = plt.imshow(arr2D,aspect='auto',extent = extent,interpolation="none", #plt.colorbar() #enable if you want to display a color bar. For a hobby project like DeepMorse I am able to run the service very cost efficiently. It may seem like a simple thing to choose a nationwide simplex frequency but VHF band plans are managed regionally. Take for example the International Space Station (ISS). The post Best VHF SOTA Antenna? An astronaut traveling on board will typically bring a 1-5 watt handheld ham radio with them. But the core thing would be to decide on a frequency and really get it in use.

The J-pole is always pointing in the right direction so you can just focus on operating and logging. Sterling is dedicated to improving ham radio by promoting it to younger generations. We may have to consider using a omni antenna instead of the Yagi. Joyce/K0JJW and I use the Arrow 3-element Yagi antenna for most of our SOTA activations, so I am very familiar with that one. AmateurLogic 152: Hands On Raspberry Pi 400. It would be great to get some comparative data on how quickly humans will learn to produce similar character error rate. I starting getting involved in the maintenance of the local machines and have helped troubleshoot and deploy a few here and there. For foreigners: BIC/SWIFT: BREXPLPWMUL PL52 1140 2004 0000 3602 3573 1928 The uses for ham radio extend far beyond emergency situations though. Local usage will likely vary depending on needs. low_cutoff = 25. The model also provides probability how confident it is about the result. (For more background on this see Simplex Channel Confusion on 2 Meters.). Ham radio projects and experiments by AG1LE. The gain of the Arrow 3-element Yagi has been measured at about 6 dBd. Whether you are taking your hobby to a SOTA, POTA, or some other "On the Air" location, the IC-705 will be your "GO TO" rig! I’ve been slow off the mark with this blog post, but years ago I posted my Top 10 PSK31 Tips for Beginners guide and it was really popular at the time. The gain of a J-pole, being a halfwave radiator, is 0 dBd. SOLID STATE TRANSCEIVER FEATURED NO TUNE OPERATION. Each matrix-element represents a score for one of the 80 characters at one of the 32 time-steps, The CTC layer either calculates the loss value given the matrix and the ground-truth text (when training), or it decodes the matrix to the final text with best path decoding or beam search decoding (when inferring), 5000 samples, split into training and validation set: 95% training - 5% validation, Each sample has 2 random words, max word length is 5 characters, Morse speed randomly selected from  [20, 25, 30] words-per-minute. Yesterday, the president of Ham-Com, inc posted this on the ham-com website: It is with a heavy heart that I write this letter about the future of Ham-Com. I  had a 80 m dipole that was not performing too well because it was only at 25 ft  height due to physical constraints in my backyard. There was some dialog around using CTCSS for signaling but nothing specific surfaced. I also enjoy fishing but it is a hobby duty in solitude or with one or two people and ham radio is more social thing. AmateurLogic.TV Episode 152 is now available for download. The hobby get your mind off of other things and it is a very good hobby to have.

Ham Radio Deluxe Amateur Radio Blog is an Authoritative Source for Amateur Radio Information with Topics of Interest to Amateur Radio Operators. The main driver for this is that 146.52 MHz can get busy with other radio traffic and/or a busy SOTA activation can tie up the calling frequency for a long time. E2D Operating methods: VHF and UHF digital modes and procedures, APRS, EME procedures, meteor scatter procedures. It did learn the character set, the structure of the Morse code and the words just by "listening" through the provided sample files. Do Both!! 369–376.

The tape would then be rewound and played back at a much slower speed so the morse could be decoded by the Radio Ham. The other benefit of serverless technologies is automatic scaling - if the service becomes suddenly hugely popular the system is able to scale up rapidly. M1KTA's QRP ham radio blog New hexbeam /Dipole 1:1 FT240-43 balun - Decided to make up the DX Hexbeam and Dipole 1:1 FT240-43 balun that had been knocking about for a … I trained  a Tensorflow based CNN-LSTM-CTC model  with 5.2 hours of Morse audio training set  (5000 files) and achieved character error rate of 0.1% and word accuracy of 99.5%  I tested the model with audio files containing various levels of noise and found the model to decode relatively accurately down to -3 dB SNR level. The basic frame measures 4.6″W x 1.3″H x 5.5″D (excluding the SO-239) and weighs in at 26oz.

I have previously written about the challenges of using 146.52: The Use of 146.52 MHz. The origins of amateur radio can be traced to the late 19th century, but amateur radio as practiced today began in the early 20th century. Spoiler Alert: the rubber duck sucks (they all do) but the Yagi and J-pole performed about the same. in the air. There are other ideas to layer on top of it, such as tone signaling so that you don’t have to hear traffic you don’t want to hear, and repeater infrastructure for announcing someone’s on the frequency with a given tone, etc. ACM, 5, 2013 George give his first impressions of the Raspberry Pi 400 Personal Computer Kit and it’s a keeper.

Demo video showing a proof of concept Alexa DX Cluster skill with remote control of Elecraft KX3 radio. Ideal to test band conditions and your equipment. If you are doing SOTA (or POTA) activations, consider using this frequency, especially if you are in an area where 146.52 is used a lot. After reading many antenna articles in the Internet and a couple ARRL antenna books I got interested in physically small HF antennas. Charlie/NJ7V and Gaston/KT1RUN did a comparison of VHF antennas during a SOTA activation. These devices often use one (or more) of the popular VHF/UHF digital formats (DMR, D-STAR, Fusion) but analog FM is also used.They allow a radio amateur to have a local RF connection into one of the extensive radio networks (e.g., Brandmeister).
