Using a Multi Meter to Measure Amps

 To use a digital multimeter (DMM) to measure direct current (DC) amps, or amperes, in a circuit, you can try these steps:

Read the manual: Understand how to safely use your specific model.

Plug in the leads: Insert the red lead into the 10 amps port and the black lead into the COM port.

Turn it on: Turn on the multimeter and set it to current mode.

Select the range: Choose the appropriate range for your application. If you're not sure what the current value is, you can start with the 10 amps port and then switch to a lower range if the value is under 200 milliamps.

Break the circuit: Connect the DMM to the circuit so it becomes part of it, breaking the circuit and forcing the current to flow through the multimeter. For example, if you're measuring the current on a breadboard, you can break the circuit by moving the resistor lead over a couple of rows.

Take the reading: You should now get a reading. 

Yaesu F-710: What is and why use AESS sound

Most people don't really understand the purpose of the AESS and why this sound system exists. Many discount it as non functional or no real functional effect. That is because most don't read the manual and most don't experiment with the sound settings.  None the less ...

WSJT-X Dark mode!

 Originally posted by GM6NX @ https://gm6nx.com/wsjt-x-dark-mode/

WSTJ-X Dark Mode! 

Your right WSJT-X can hurt your eyes because of the white glare from the screen. Well this guide will show you how to turn WSJT-X into dark mode.

Step one – create a new short cut from the WSJT-X.exe file to your desktop. You will find this in the C: drive or what ever letter your hard drive is.

Step two – rename your short cut to something you will known that it is the dark mode version, I called mine “WSJT-X – DARK”

Step three – Right click on the short cut and select properties.

Step four -click in the target section

Step five – after the wsjtx.exe add the following

–stylesheet :/qdarkstyle/style.qss

Step six – click apply then OK.

Step seven – click on your new short cut and open up WSJT-X – remember to change the colours to suit your own needs inside the wsjt-x program.

How do I know if a band opens up?

First off! what is meant by a band opening up? Simply that the atmospheric conditions (solar flares, meteor scatter, tropospheric ducts, sporadic E layer density changes) and their effect have formed in a way that is conducive to bouncing and bending radio waves for extremely long distances. Thus opening up good communication between distant stations.

Tropospheric Ducting: As per Google.com AI "Ducting occurs when the refractive index of the atmosphere rapidly decreases with height, which leads to ray trajectories bending inward towards the surface of the Earth, effectively creating a waveguide and enabling long-distance communication. "Temperature and it's changes seem to be key in taking advantage of Tropospheric Ducting. Click this link to view the Tropospheric Ducting Forecaster. Additionally stated "Tropospheric ducting is when the atmosphere allows radio waves, including those used for high frequency transmission, to travel long distances due to temperature and humidity variations. It can extend your signal range but may also cause signal fluctuations and interference, depending on atmospheric conditions" 

Sporadic E: As per Google.com AI and Wikipedia.com "Sporadic E propagation reflects signals off relatively small ionization patches in the lower E region located at altitudes of about 95~120 km (50~75 miles)." and  "Sporadic E Layer refers to a mesospheric phenomenon characterized by the occurrence of temporary enhancements in the density of the E layer of the Earth's ionosphere. These enhancements are observed to last from a few minutes to several hours and are associated with specific latitudes and times of day." 

How do we know or predict these conditions?  HF Propagation and Terrestrial Data Website offers extensive data on RF conditions.  The data is available as a widget for Windows or your website. You can look up band availability anytime. Was weeks before I realized one could simply look up the propagation conditions as opposed to trial and error.
