Rebuilding a Clansman 1Ah 24 Volt Battery

-

By  Michael Kennedy (EI6IRB) The objective was to undertake a basic rebuild of a 1Ah 24v alkaline Clansman radio battery (NSN 6140-99-620-8058) to allow it to be used on various Clansman radios, particularly the PRC-320 and PRC-351. The battery arrived among the ancillaries with a recently purchased PRC319. It was manufactured in July 1989. Unlikely to charge, let alone hold a charge, the battery was test-charged under constant observation using a standard Clansman 28v battery charger (NSN 6130-99-117-0450). The battery case soon became hand-hot and after ten to fifteen minutes it began leaking battery content which appeared to ‘boil’ and bubble out of the top of the unit. Unsurprisingly, the battery did not hold a charge. As anticipated, it was unserviceable. As the case was in a very good cosmetic condition, there was every chance that the battery could be refitted with a similar voltage and ampere battery and made serviceable again. The first task was to open the unit and remove...

East Leinster Amateur Radio Club have had a Plane Crash!

OK, it was only a pretend crash, but it was a great scenario for a training exercise. The East Leinster Amateur Radio Club has been out practicing again – remember our “Black Sky” event earlier this year! This time the project was a bit more adventurous. We got together with the Glen of Imaal Mountain Rescue Team (MR) and with Wicklow Civil Defence (CD) to run a combined operation to practice and hone our skills with simulated emergency communications. We also had a guest observer from the Wireless Communications Laboratory at the Tyndall Institute with us. The Glen team responded to an imaginary small aircraft crash in the Ow Valley (just south of Lug na Coille). This carefully chosen location near Aughavannagh had no mobile phone signal, no Tetra radio signal and was very definitely out of line-of-sight for VHF signals. The background to the exercise was to simulate the failure of the Tetra radio system operated by the emergency services, and to assess the feasibility of using HF ...

Black Sky Exercise 2023

-
Image
Introduction On Saturday the 27th of May the members of the East Leinster Amateur Radio Club (ELARC) conducted a Black Sky drill amongst the sunny Wicklow mountains. Some background to the drill. A Black Sky drill is a simulation of a major extended power outage. The power outage can be either man made, such as an electromagnetic pulse, a cyber-attack on the grid or a physical attack on the power distribution network. It can also be caused by a natural phenomenon such as a coronal mass ejection similar to the Carrington event of 1849 which wiped out large sections off the early Telegraph system in the United States. Causing Telegraph stations to burst into flames. Other causes can be winter ice storms, hurricanes, or other major weather events. These black sky events are typically very rare but have a very high impact to the electrical distribution grid. Training Goals This drill is a scripted, Directed Net with some specific training goals: Improve operator message handling skills. Be...
