![[Request] How much earth is actually required to safely earth a cable?](https://preview.redd.it/p0nrzxqdih0h1.png?auto=webp&s=d555faea26d0ac5599336665641049407a29abe6)
Say a typical domestic electrical supply into earth with pretty average parameters (conductivity etc).
Let's say earthed into a perfectly insulated container of X mass soil - what is X?
I’m looking for a few ham radio / CW folks willing to test an early beta of my iOS / iPadOS app, Morse Code Visual Trainer.
It teaches Morse visually with a binary tree, guided dot/dash practice, listening drills, a single-button key mode, and several training exercises.
I’m especially looking for honest feedback from people who know CW: what feels right, what feels wrong, what’s missing, and what would make it more useful.
Beginners are welcome too. You do not need to already know Morse code to help test it.
I’ve attached a few screenshots. If you’re interested in TestFlight access, email me at mcvt@forwardtechnologies.com
I recently passed my General Exam and invested in a second hand G90. I bought one of the Ali Express 17 foot whips for 20 meters and so far it has performed pretty well. I’ve heard operators from the US and Mexico here near Little Rock. Reception is clear for the most part. The issue I’m having is when I transmit my call sign and CQ I’m met with silence. The radio face display shows all indications of my transmission going out. Do I assume the whip is the issue? I’m going to put up a half wave dipole soon to see if that helps. Anyone have any ideas or suggestions?
Got a td-h3 today, I’ve been figuring out the controls
Not quite sure what to do next, but I found the ems frequencies, and I’m now listening to the dispatches
