    Portable Power Bank Assistance

    If you do a internet search for 12 volt ATX power supply you can find them as a factory built off the shelf product. There is a device that goes by different brand names that uses the Venturi Effect of water pressurized by a reliable public utility to draw water out of a sump and expel it...

    Emergency portable local radio communication

    This is something that a lot of people do not understand. No government agency, at any level, can issue enforceable regulations in the absence of enabling legislation that empowers that agency to do so. The regulations can not go into effect until after a public comment period which allows...

    Portable Power Bank Assistance

    AGM batteries are appropriate if it will not get really cold inside the building. If it will get really cold then Gel Cell batteries become the way to go. If you want to maximize run times and minimize complexity and cost of ownership then Lithium Iron Phosphate (LiFePH4) batteries are the best...

    Radio & disaster response

    I have used a High Frequency (HF) radio and Near Vertical Incidence Skywave Propagation to communicate across the entire state including the mountainous portion to the western side of the state with no problem whatsoever. The radio we used was about the size of an older portable radio and the...

    Radio & disaster response

    Poppy There are 3.7 volt lithium cells with a AA cell form factor. 3 of those with one dummy cell in a 4 cell pack would bring the voltage up to 11.1 volts. 2 of those with 2 dummy cells would bring the voltage up to 7.4 volts. Do you suppose either of those would cause the radio to reach it's...

    Good drop in for 3 D cell Maglite?

    I'll do a photo of all of the staff and counselors who are over 18 and willing to be photographed. That's the best I can do given the Baltimore Yearly Meeting of Friends' (Quakers) youth protection policy, which forbids photographing anyone under 18 years of age without the consent of their...

    Kenwood THD7A, THF-6A, YAESU FT-470 7.4 VOLTS YES No these are portable radios They will not put out their designed highest power of 5 watts when the lithium Ion batteries are discharged and you have to resort to clam-shell packs of primary batteries. The manufactures design the primary...

    You know you could upset the balance of the universe by talking sense like that. It's a basic principal of science that the universe has a natural tendency to a greater state of disorder. If I remember correctly it's called entropy. [Well at least the spell checker likes it unlike a lot of...

    That is a great tip but first I'm going to have some present and past counselors try the lights I've already been sent and find out which type suits them best. Since I'm not going to be with them out on the trail I feel I shouldn't foist my choice on them. The gathering were that will be...

    I can guarantee to a certainty that we will put them to work. We operate 3 camps with at least 100 campers per session apiece. I don't remember the counselor ratio off the top of my head but I know that it is at least 1 counselor for every 10 campers at the very least. They will make great in...

    It seems I've managed go hijack my own thread. I have mixed up 2 radically different uses of flashlights. I regret not having been more careful. I'm a safety advisor for my church's youth summer camp program. I'm working with the Camping Program Committee on providing appropriate equipment for...

    Need brand of Torx set were the drivers fold into handle and the shafts are the same diameter as the bits.

    I didn't follow your question but let me explain that when a Torx set screw is well down a threaded shaft hole if the driver has a larger shaft than the outside dimension of the Torx tip itself it will not reach all the way down the shaft it will hang up on the opening of the set screw threaded...

    If they gotta then they gotta. Something that happens during disaster relief efforts is that we get asked to do "Other duties as assigned." We're radio operators but if what they need is evacuation route guides we're that to. Yes we do work long hours without any real breaks. A couple of protein...

    Need brand of Torx set were the drivers fold into handle and the shafts are the same diameter as the bits.

    Can anyone recommend a brand of Torx fold into handle driver set that does not taper the bit end smaller than the shaft. Recessed set screws, such as the one used in a Maglite switch, can not be reached if the shaft is larger than the bit. Tom Horne

    I won't know what will be enough. I'm getting opinions from 200 up to 1200 and some much higher. That's why I'm going to ask current and recent counselors and camp staff to make that judgement. Now that you have made me aware that there is a range of performance in Alkaline cells I'll buy a...

    I am also an Amateur Extra Class Licensed Amateur Radio Operator. We have some folks looking into the Garmin system. We would only need to have one for each trip team. The camp program committee is looking for funds to undertake their use for this season. As you may have seen from something I...

    So you are personally acquainted with children between 2nd grade and eighth grade; which is the age group our camps serve; that would cheerfully tolerate wearing bells like those worn by Morris Dancers on their hiking trips. Really? OK. I myself have no experience with even one single child who...
