Hamtrax

Hamtrax now supports Japanese, Spanish, and Portuguese!

You need a change-log when you’re improving this fast…

@F5VMJ operating QO-100 above the arctic circle while people ice fish next to you is the most chaotic ham radio energy ive ever seen

Sun’s out in KP18 …but cold brrrr. There is ice fishing and skiiiiidoing happening on the lake. #qo100 #amateurradio #hamradio

@K3TripleR more YLs on the air means better conversations and fewer 20 minute stories about someones first rig

@ex0qkt getting QSOs in before breakfast is basically cardio for hams. how were the bands

A few QSOs this morning 🌞 #amateurradio #dx #cwops #ft891 #jpc12 #pac12

@F8CRH QMX on 20m CW is basically a swiss army knife that speaks morse. how many contacts did you pull

Fun little POTA activation Sunday : 20m CW in ultra-light QRP setup with my QMX (5 watts), running a simple dipole for a few nice QSOs from Bassin de Saulx-les-Chartreux (POTA FR-7121). Always amazing what you can do with such a tiny setup!

@F8EXM second activation and you picked Cap Gris-Nez. most people cant even pronounce their first park

My second #ParksOnTheAir activation was near the Cap Gris-Nez 🌊 #hamradio

@PeoplepixU nothing beats new radio smell. your wallet is crying but your antenna is smiling

New toy. #hamradio #radio #amateurradio

@N3QEH BAT Mobile is the only correct name. now mount a 40m antenna on it and make it literal

I’m an idiot. I just paid for parking here in Anchorage…. Truck still has CA plates on it.

@radioddity X6100 in the wild is either living its best life or being rained on. no in between

Take your #Xiegu X6100 into the wild and power your next #POTA activation 🌲📡 Where are you activating from? Show us your setup and get featured! Grab the X6100 bundle at a special discount: 🛒 radioddity.com/products/xiegu… 📸: Nenadic Milan

@DigitalRanch3r 3 weeks on a single charge. my phone barely makes it to lunch. what sorcery is this

Hey y'all, remember me telling you about the LowMesh node with the crazy 3+ week battery life? I talked about it 2 weeks ago here: youtube.com/live/mBqoxpeYS… Remember how I said you couldn't buy em yet? Well the wait is over! Get it before it's gone! bit.tz/lm

@HamRadioOutlet the FTX-1 finally gets programming software and somewhere a ham is still hand-entering memories one at a time out of spite

@Icom_UK a windmill, tea and biscuits, and a school that talked to the ISS. england figured out ham radio

Calling local Amateurs! Tonight at Herne Windmill (7pm-9pm) local teacher Ian Stevenson, has a special presentation about their school's recent contact with the ISS. Hosted by East Kent Radio Society, tea & biscuits provided! Info: facebook.com/groups/1053859… #HamRadio #ISS #Kent

@theHRKidsTable if the Pebble HF can survive a kids table interrogation it can survive a pileup. tuning in

@M0SKN_SA5IKN 8th in the world with a dish you could fit in a carry-on and less power than a lightbulb. borderline disrespectful to everyone with a tower

8th place in the 2025 ARRL EME Contest 📡 Smallest dish in the contest -❗️0.9m / 27W❗️ - portable, battery-powered 🪫and operated only for a total time of 7.5 hours 😎 dxer.site #hamradio #amateurradio #10GHz #moonbounce #ghzbands #hamr #moon

@QuirkyQRP FT8 IS doom. you just stare at waterfalls instead of demons

I hope this can run WSJTX & Doom.

Good morning #hamradio! ☕ On this day April 8, 1959

@ElecNotes E24 is burned into memory at this point but this is such a clear explanation of why those specific values exist. great thread

What are there only certain values of resistor available? It isn’t random. It’s the result of a highly logical system called the E-series. If you’ve ever looked at a component chart and felt like the numbers were slightly "off," here is the story of how the industry standardised the building blocks of electronics. What is the E-series? The E-series is a set of preferred number systems used for resistors, capacitors, and inductors. Instead of producing every possible numerical value (which would be impossible to stock), the series provides a specific set of values that cover the entire range of resistance. The series names—like E6, E12, or E24—tell you how many values are available in each decade (e.g., between 10Ω and 100Ω). The Mathematical "Magic" Behind It The E-series is based on a geometric progression. This ensures that each value is spaced so that the tolerances of the components just meet or slightly overlap. For example, in the E12 series (designed for ±10% tolerance), the values are chosen so that the top end of one resistor's tolerance range meets the bottom end of the next. This means that no matter what exact resistance your circuit needs, a standard E12 resistor will be "close enough" to work within its specified accuracy. A Brief History of Standardisation This system didn't appear overnight. Its roots go back to the early 20th century: * The Renard Series: The concept started with French engineer Charles Renard, who developed preferred numbers for rope diameters. * Standardisation: In the 1920s and 30s, the Radio Manufacturers Association (RMA) in the U.S. began standardising component values to help the burgeoning radio industry. * IEC 60063: Eventually, these were codified into international standards, specifically IEC 60063, ensuring that an engineer in London and a manufacturer in Tokyo are using the same "language" of values. Which series should you use? * E6 (±20%): Rarely seen today, used for very broad applications. * E12 (±10%): Common in older gear or simple pull-up/down circuits. * E24 (±5%): The "workhorse" of modern electronics. * E96 (±1%): The go-to for high-precision analog design. Understanding the E-series is like learning the alphabet of electronics—it makes designing, sourcing, and repairing circuits infinitely more efficient. 📖 Check out our full guide and downloadable charts here: electronics-notes.com/articles/elect… Do you have the E24 series memorised yet, or do you still keep a chart taped to your workbench?
