 Not scary, frightful, just frightful activity wise.

I got soaked coming home on Friday. I was following the weather and radar all day and was expecting thunderstorms here at work when I left for the day. It was bone dry, but the skies were darkening. All the way on the drive home, I could "feel" that darkness behind me, rather then see it in the rear view mirror. As luck would have it, as dark as it was, it didn't rain and I thought I would beat the storm home. As I got out of car in front of the house (I park on the street), there was a cloudburst. It began raining at a rate of over an inch an hour, with huge, heavy drops that actually hurt when they landed on my arms. I got drenched enough that I had to change clothes once I got inside.

That set the tone for the weekend's weather. It was so humid that the lawn didn't dry out all of Saturday, so we couldn't mow. And that was actually a good thing as the temperature/humidity index made it feel like it was over 100F. We probably would have ended p with heat exhaustion. I told my son that if worse comes to worse, we'll buy a sheep. HI! We ended up getting hit with more thunderstorms and about 0.69 inches of rain later in the afternoon. I was going to grill burgers for dinner, but had to resort to indoor cooking instead.

On Sunday, I got on HF for a little bit around 1:00 PM (17:00 UTC). The bands were a mess. I did not hear anyone on any band except for 20 Meters, where I heard a solitary station, NM8GS around 14.038 MHz. 

It was the light ship Huron that was on the air for Lighthouse and Lightship Weekend. They was calling CQ and I worked them easily on the first try.  That was when I looked up at HamClock and saw that the K Index was at 6.3. Argh! The bands were pretty much a wasteland. Speaking of which, I just recently downloaded the SpaceWeatherLive app onto my phone.

To protect lithium batteries from cold while charging, a video/blog showcases using a Chinese diesel heater in an off-grid ham shack. It's vital to keep batteries above freezing, a lesson learned from electric cars in winter. The video details the installation and operation of a 3kw Vevor diesel heater, which also powers up using the ham shack's LiFePO4 batteries, maintaining ideal temperatures for both batteries and equipment.

This video shows charging Power Queen LiFePO4 batteries with a vertical wind generator and discusses off-grid ham shack power storage solutions, including during non-solar conditions.

I had an ambitious set of goals for 2023:

• Teach a class (either Technician or CW Academy)
• Participate in 120+ CWTs for the CWops Gold Medal
• Build my QRP-Labs QDX Digital Transceiver
• Activate 10 new parks in CT or obtain award for hunting 1000 parks
• Obtain 50 States Parks on the Air award

I completed four of the five, only failing to build the QDX transceiver.  It sits on my desk and perhaps will come to life in 2024.  I did complete 145 CWTs (actually 146 but I forgot to submit a log for one of them).  I also taught a Technician class in the spring of 2023.  For POTA I did get the WAS award, and hunted more than 1000 parks.

For 2024, I think I’m going to dial things back a bit, but here we go:

• Hunt 1500+ POTA parks
• Do at least one activation with the Elecraft KH1 hand-held QRP rig
• Give a radio club presentation on solar power/batteries
• Compete in 120+ CWTs
• Wildcard (like finish the QDX or some other ham related project)

This tutorial demonstrates how to connect two 12-volt batteries in parallel using Power Queen 12.8V, 100Ah, 1280Wh lithium iron phosphate batteries. The provided YouTube link offers a detailed guide.

The Off-Grid Ham Shack series discusses creating a self-sufficient ham radio station or 'Ham Shack' capable of operating on solar power during any grid down scenario, emphasizing the importance of an energy strategy for off-grid communications. This system includes solar panels, a charge controller, battery, and power distribution system. Key elements are the use of photovoltaic (PV) panels to harness solar energy, a solar charge controller to regulate energy flow and prevent battery overcharging or damage, and a battery to store energy for later. As well, power distribution ensures the allocation of power to multiple devices simultaneously. A grid-down energy strategy is crucial to any communication-related emergency, be it CB, FRS, GMRS, MURS or PMR radio, UHF CB, DMR, DStar, Meshtastic or LoRa communications.

The blog post highlights the benefits of Power Queen LiFePO4 batteries for off-grid projects over traditional lead-acid batteries, focusing on the better performance and cost-effectiveness in the long run. Additionally, it provides subscribers with information and discounts on Power Queen's Christmas offers, and illustrates how LiFePO4 batteries function in an off-grid system. It also includes descriptions and respective links of the batteries suited for specific needs in the US, Europe, and Canada.

The author discusses choosing a solar charge controller suitable for radio communication. He focuses on three criteria: portability, radio frequency quietness, and Maximum Power Point Tracking (MPPT) functionality. Recommending Genasun due to its compatibility with these requirements, he mentions his dissatisfaction with another brand, Victron, that caused excessive radio frequency noise. For optimal results, he suggests keeping devices DC powered and using no inverters. He provides specific instructions about matching controllers to battery and solar panel specs, and suggests parallel configuration for Genasun controllers.

The post warns against the use of QRO radio systems for off-grid or grid-down situations due to their high energy consumption. Instead, it advocates QRP radios, suggesting they offer greater efficiency and ease of use with renewable energy sources such as solar. The post also dismisses the idea of lowering the transmission power of QRO radios as a solution, arguing that it does not address issues with energy inefficiency and that such advice is misguided.

A classic never goes out of style. Way back in 2016 I posted the Off Grid Ham 100 Watts for $300 Solar Plant. Even today, that article is still hugely popular and one of the most viewed posts on this website. In a 2020 update, the $300 threshold not only... Read more »
