GMRS needs one licence that covers your whole family. Ham needs an exam per person. Which one fits a household. https://heldinreserve.com/skills/gmrs-repeaters-extending-range/ https://heldinreserve.com/skills/gmrs-repeaters-extending-range/ Tue, 15 Sep 2026 12:00:00 GMT skills A repeater swaps your handheld's horizon for one on a hill. What repeater channels are, how to use one, and why this is the real reason to hold a GMRS licence. https://heldinreserve.com/skills/household-communication-plan/ https://heldinreserve.com/skills/household-communication-plan/ Tue, 15 Sep 2026 12:00:00 GMT skills An out-of-area contact, a meeting point, a check-in time and a written card. The part of emergency communication that costs nothing and gets skipped anyway. https://heldinreserve.com/skills/satellite-messenger-vs-plb/ https://heldinreserve.com/skills/satellite-messenger-vs-plb/ Tue, 15 Sep 2026 12:00:00 GMT skills A PLB signals government search and rescue and does nothing else. A satellite messenger sends text and needs a subscription. The difference matters most on the worst day. https://heldinreserve.com/skills/two-way-radio-real-range/ https://heldinreserve.com/skills/two-way-radio-real-range/ Tue, 15 Sep 2026 12:00:00 GMT skills Blister packs claim 35 miles. The regulation caps a handheld low and the signal travels line of sight. Here is what a two-way radio actually does. https://heldinreserve.com/defense/less-lethal-carry-jurisdictions/ https://heldinreserve.com/defense/less-lethal-carry-jurisdictions/ Tue, 18 Aug 2026 12:00:00 GMT defense A device legal in your state is still restricted in federal facilities, on school grounds, in airports, and the moment you cross a state line. State-by-state tables cannot show you this layer. https://heldinreserve.com/defense/less-lethal-failure-rates/ https://heldinreserve.com/defense/less-lethal-failure-rates/ Tue, 18 Aug 2026 12:00:00 GMT defense Every less-lethal device has a documented failure rate against real subjects. The category's marketing never mentions it, and the failure modes are specific enough to plan around. https://heldinreserve.com/defense/pepper-spray-delivery-formats/ https://heldinreserve.com/defense/pepper-spray-delivery-formats/ Tue, 18 Aug 2026 12:00:00 GMT defense The active ingredient is the same across formats. What changes is range, wind behavior, blowback risk, and how much of it ends up on you instead of on them. https://heldinreserve.com/defense/stun-gun-vs-taser-mechanism/ https://heldinreserve.com/defense/stun-gun-vs-taser-mechanism/ Tue, 18 Aug 2026 12:00:00 GMT defense A contact stun device causes pain. A probe deployment causes loss of muscle control. These are different physiological effects, and the marketing for the cheaper category depends on the confusion. https://heldinreserve.com/food/buckets-lids-seals/ https://heldinreserve.com/food/buckets-lids-seals/ Tue, 18 Aug 2026 12:00:00 GMT food A bucket is a rodent and impact barrier, not an oxygen barrier. Which plastics are food safe, what a gamma lid is for, and why sealing food directly in a bucket is the wrong architecture. https://heldinreserve.com/food/insect-eggs-pretreatment/ https://heldinreserve.com/food/insect-eggs-pretreatment/ Tue, 18 Aug 2026 12:00:00 GMT food Grain arrives with insect eggs already in it. Oxygen absorbers kill every life stage on their own, which makes most pretreatment redundant, and the exceptions are specific. https://heldinreserve.com/food/mylar-bag-thickness/ https://heldinreserve.com/food/mylar-bag-thickness/ Tue, 18 Aug 2026 12:00:00 GMT food Thicker mylar buys puncture resistance, not a better oxygen barrier. The barrier comes from the aluminum layer, and the failure mode that matters is the seal, not the film. https://heldinreserve.com/food/oxygen-absorbers-sizing/ https://heldinreserve.com/food/oxygen-absorbers-sizing/ Tue, 18 Aug 2026 12:00:00 GMT food Absorber charts size against container volume, but the oxygen is in the air trapped between the grains. The correct calculation uses headspace, and most people under-dose by half. https://heldinreserve.com/food/shelf-life-sources-table/ https://heldinreserve.com/food/shelf-life-sources-table/ Tue, 18 Aug 2026 12:00:00 GMT food Every shelf-life chart in the preparedness niche is published by someone selling storage bags. This table gives the numbers with the source, the storage conditions, and whether anyone actually measured them. https://heldinreserve.com/power/appliance-wattage-table/ https://heldinreserve.com/power/appliance-wattage-table/ Tue, 18 Aug 2026 12:00:00 GMT power Typical running and surge wattage for household appliances, with the reasons the numbers vary and instructions for finding your own rather than trusting a chart. https://heldinreserve.com/power/charge-and-run-simultaneously/ https://heldinreserve.com/power/charge-and-run-simultaneously/ Tue, 18 Aug 2026 12:00:00 GMT power Pass-through charging works on most modern power stations, but net charge rate is solar input minus load draw, and some units handle the simultaneous job badly enough to matter. https://heldinreserve.com/power/energyguide-label-backup-power/ https://heldinreserve.com/power/energyguide-label-backup-power/ Tue, 18 Aug 2026 12:00:00 GMT power The yellow EnergyGuide label on your refrigerator holds the one number that actually sizes a battery or solar system, and two numbers it deliberately leaves out. https://heldinreserve.com/power/lifepo4-vs-lead-acid/ https://heldinreserve.com/power/lifepo4-vs-lead-acid/ Tue, 18 Aug 2026 12:00:00 GMT power Lead acid gives up half its rated capacity to depth-of-discharge limits and lasts a few hundred cycles. LiFePO4 costs more up front and less per usable kilowatt-hour over its life, with real exceptions. https://heldinreserve.com/power/portable-panels-vs-permanent-array/ https://heldinreserve.com/power/portable-panels-vs-permanent-array/ Tue, 18 Aug 2026 12:00:00 GMT power Portable panels cost three to five times more per watt and produce less, but they work during an outage without a battery, a permit, or an inverter replacement. When each one is the right answer. https://heldinreserve.com/power/rooftop-solar-blackout-shutdown/ https://heldinreserve.com/power/rooftop-solar-blackout-shutdown/ Tue, 18 Aug 2026 12:00:00 GMT power Grid-tied solar systems disconnect the moment the utility goes down, by design and by code. What anti-islanding is, why it exists, and what it takes to keep your panels working in an outage. https://heldinreserve.com/power/solar-panel-derating-real-output/ https://heldinreserve.com/power/solar-panel-derating-real-output/ Tue, 18 Aug 2026 12:00:00 GMT power A 200W panel produces closer to 130W in good conditions and far less in bad ones. The five losses between the label and the battery, and how to derate honestly. https://heldinreserve.com/power/solar-panels-recharge-power-station/ https://heldinreserve.com/power/solar-panels-recharge-power-station/ Tue, 18 Aug 2026 12:00:00 GMT power Refilling a 1,000Wh power station in a single day takes roughly 300W of panel in summer and 700W or more in winter, and the station's input limit often decides the answer before the panels do. https://heldinreserve.com/power/watts-vs-watt-hours/ https://heldinreserve.com/power/watts-vs-watt-hours/ Tue, 18 Aug 2026 12:00:00 GMT power A power station named for its watts is sold on its watt-hours, and the two numbers answer completely different questions about whether your backup power will work. https://heldinreserve.com/power/what-power-stations-cannot-run/ https://heldinreserve.com/power/what-power-stations-cannot-run/ Tue, 18 Aug 2026 12:00:00 GMT power The loads that sit outside the reach of portable battery backup regardless of budget, and the physical reasons the marketing never mentions them. https://heldinreserve.com/water/bleach-water-treatment-dosing/ https://heldinreserve.com/water/bleach-water-treatment-dosing/ Tue, 18 Aug 2026 12:00:00 GMT water Household bleach got stronger and most dosing charts did not change. The familiar per-gallon figure is keyed to the old formulation, and a government page is still publishing it. https://heldinreserve.com/water/does-stored-water-go-bad/ https://heldinreserve.com/water/does-stored-water-go-bad/ Tue, 18 Aug 2026 12:00:00 GMT water Water itself does not expire. What degrades is the container, the seal, and anything that got in when you filled it, which is why the six-month rotation rule is about your filling technique rather than about chemistry. https://heldinreserve.com/water/gallon-per-day-number/ https://heldinreserve.com/water/gallon-per-day-number/ Tue, 18 Aug 2026 12:00:00 GMT water FEMA says one gallon. Most preparedness sites now say two. The disagreement is about scope rather than facts, and knowing what the original figure excluded tells you which number you need. https://heldinreserve.com/water/water-already-in-your-house/ https://heldinreserve.com/water/water-already-in-your-house/ Tue, 18 Aug 2026 12:00:00 GMT water A water heater holds 40 to 80 gallons of potable water most people never count. The procedure to get it out has three steps that matter, and doing them in the wrong order damages the heater. https://heldinreserve.com/water/water-storage-containers/ https://heldinreserve.com/water/water-storage-containers/ Tue, 18 Aug 2026 12:00:00 GMT water A used juice jug works and a used milk jug does not.
