In most Solar Systems what causes more QRM on HF ham bands, the panels, the charge controller, or the distribution system?

The panels themselves are essentially photodiodes, producing DC when exposed to light, and so generating no RFI. A very simple system consisting just of panels and a battery could generate no RFI at ...

In most Solar Systems what causes more QRM on HF ham bands, the panels, the charge controller, or the distribution system?

In the April 2016 issue of the ARRL's QST magazine article, "Can Home Solar Power and Ham Radio Coexist?," K1KP tracks down and attenuates RFI generated by his multi-kW rooftop solar ...

What steps to take to secure for G2 geomagnetic storm?

Nothing. A G2 storm is a common event; according to NOAA data it happens an average of 600 times per 11-year sunspot cycle. It won't hurt your radio, but it might make HF communication a little more ...

Working satellite on 2 meters, at what arc distance to sun (center) will noise floor be problematic to a disruption of a communication path?

It depends on the gain of your receive antenna, your system noise temperature, and how much link margin you had in the first place. The moonbounce (EME) community use Sun Noise as a measure of their ...

Is it possible to power your ham radio station by solar power? If so, how?

Yes, it's possible. Photovoltaic panels convert solar radiation to electrical power. Why wouldn't it be possible to run a station, or any other electrical device, on solar power? Most amateur radio ...

How would you design a power controller for battery, solar, and mains power?

There are a couple of issues with trying to design something like this. First, the lithium batteries are finicky about how they are charged. For the health of the battery, it would be a good idea to ...
