Ham Radio Camper Caravan Part 2 | Off-Grid Power
The Ham Radio camper caravan trailer gets some off-grid solar-powered updates.
Today we look at the the off-grid goals for the camping trailer. We also look at using a raspberry pi and Elecrow 7inch touchscreen, to build Victron VenusOS power management system. This should make it easy to monitor the Power Queen LiFePO4 battery, the generated energy from the new AllPowers solar panels, and current load from all the portable ham radio gear. With all these updates, the camper trailer should be completely sustainable, anywhere it is deployed.

Portable Ham Radio on Solar Power: Basics
Portable Ham Radio on solar power can be very rewarding. You generate your own energy from the sun, power you own off-grid ham radio station, and you are completely self-reliant during a grid down emergency. The experience is priceless!
In this video we discuss the component required for a 12 volt DC solar power system and battery storage. We go through our component choices, show how to wire up the system, and also how and where to test your new portable solar power system, for portable ham radio ops.
This video is supported by PowerFilm, Genasun, and Power Queen

Portable Ham Radio with a Microsoft Surface
Portable ham Radio data modes can be frustrating if you don't have the right portable tablet or laptop computer. In this video, we will go through using the Microsoft Surface, for ham radio data mode communications like Winlink, JS8Call, FT8, RTTY and so on. We'll also discuss screen and drop protection for the Microsoft Surface, setting up the GPS to work ham radio applications, and useful additions like snap-on keyboards.

The Retevis Ailunce HD2 DMR radio is amazing!
A few weeks before this post was published, Retevis reached out to ask if I would test an update to the Retevis Ailunce HD2. I've been using the Retevis Ailunce HD1 since late 2023. Both are capable radios! The HD2 takes DMR to another level with IP67 ingress protection, Bluetooth audio, AES128 & AES256 encryption and much more.

Portable Ham Radio Antenna Care package from N9SAB
The Portable Ham Radio antenna is the keystone of a successful portable ham radio field day or excursion. The lightest and most efficient ham radio antennas available to the portable radio operator, are the dipole, off center fed dipole, and end fed half wave antennas. Tim N9SAB has sent over a care package containing some very interesting ultra-lightweight and ultra-efficient antennas for portable and fixed station use.
The package should include signal and multiband dipole antennas, end-fed half wave antennas, and man-portable backpacking antennas, all being lightweight, and extremely efficient. Any of these antennas would be at home on a SOTA summit, on a POTA activation, or a ham radio backpacking trip with one of the ultra-portable QRP radios available today.
Let's do an unboxing together, and see just what Tim sent over.

My Off-grid & Grid-down Comms energy strategy
The off-grid ham shack is now 100% energy self-reliant. It has taken some time to develop an effective grid-down energy strategy. Today, the station acting as a TOC (Tactical Operations Center, can stay in the fight during a prolonged grid-down disaster.
This video covers batteries, solar power, wind generator, hand crank generator, power distribution, and much of the comms gear used off-grid, in the station.
HUge thanks to @S2Underground for inspiring this video!

QRP Ham Radio QSO with JD8Call
QRP JS8Call Ham Radio QSO with an Icom IC-705 run73
Julian oning at 10 watts. I was recording cls for another video project, when GW4PZU came in on 20 meters. I was already running the camera gear, so I sent him a shout back.
The video is kind of chillaxing or boring (your perspective). However, it does show the power and capabilities of JS8Call fr low power HF communications.

Keeping Lithium battery warm in winter

Off Grid Ham Shack for Emergency Communications | Part 1
Welcome to the Off-Grid Ham Shack series, part 1. In this video we go through putting together an off-grid ham radio station, powered by a Power Queen 100ah lithium Iron phosphate battery, Renogy solar panels, and Genasun charge controllers. The purpose of the completely off-grid radio station is emergency communications, survival radio, and ultimately preparedness in group communications during a grid-down disaster.
