Hello everybody and welcome back to the Everything Ham Radio Podcast! In this episode we are going to talk with Ben Doran, N8BD, about Near Vertical Incidence Skywave or NVIS for short(since I have the hardest time saying Incidence…lol).
Tech Corner – Near Vertical Incidence Skywave
What is Near Vertical Incidence Skywave (NVIS)
NVIS is an ionospheric skip operating technique that directs the strongest signals from a station vertically, or upward, rather than toward the horizon. Signals propagating nearly vertically approach the ionosphere with steep incidence angles and may be bent back to earth with similarly small angles.
NVIS is a great mode to use when you are trying talk that that area that is to far away for VHF/UHF but really to close for standard HF. It is great for emergency communications like during a natural disaster. It takes very little to setup and use.
Thank you for you support

West Mountain Radio
Do you have an old fashioned Analog Volt and Amp meter hooked to your station? Are you looking to find something that has more bells and whistles? Check out the West Mountain Radio PWRcheck.
The PWRcheck has eight display modes including voltage, current flow in either directions, wattage and amp-hours and will measure from 0-60V with 40A continuous load. It is accurate to within +/- 10mV and +/-10mA.
It has a backlit graphics LCD that will display data in digital, analog and bar graph formats. You can even monitor your backup battery with a programmable “gas gauge”.
The non-volatile memory stores more than 100,000 data points without power. That is nearly two and a half months worth of data @ 1 point per minute!
It has a USB computer interface for configuration and data download and you can program it to sound an alarm for over current, over or under voltage and amp-hours.
The software that comes with it allows your to program every aspect of the PWRcheck operation such as data logging rate, display formats and alarm conditions. You can display current, voltage, wattage and amp-hours in real time. It has integrated charting software that automatically collects and displays data. All the data can bed downloaded and stored for later analysis!
