	There is also a weather station located at the site; data is available from [https://www.wunderground.com/dashboard/pws/KORBROOK132 Weather Underground, station ID KORBROOK132].		There is also a weather station located at the site; data is available from [https://www.wunderground.com/dashboard/pws/KORBROOK132 Weather Underground, station ID KORBROOK132].

			The site is owned by Harbor Water. Only PBARC property is allowed at the site, and all equipment must be labeled. Cameras are forbidden due to privacy concerns.

	== Electrical measurements ==		== Electrical measurements ==

	The shack ~~has only one~~ 20 A ~~breaker~~, ~~from the control shack at the site compound. We~~ should ~~not have more~~ load ~~than~~ 16 A ~~on our 20 A breaker,~~ to ~~prevent~~ tripping the breaker in the ~~summertime~~.		The shack is on a 20 A circuit. However, we should keep our load below 16 A to avoid tripping the breaker during hot weather. It seems that some of Harbor Water's equipment is on the same circuit.

	~~It appears that some water controls use the same multi-conductor cable as~~ power ~~in.~~		=== AC power ===

	~~The power feed to the control shack is 480V, through a transformer, to a breaker subpanel, then to conduit to us.~~

	~~=== AC power ===~~		The 2 m repeater draws 12.25 A when transmitting (50 W RF output). This leaves about 3.75 A for other equipment.

	* 2 m repeater~~: 12~~.~~25A on 50W TX~~ (~~not much overhead for other gear~~)		The DMR repeater draws 1.03 A when transmitting (15 W RF) and 0.25 A when quiescent.
	* DMR repeater: 0.~~25A~~ quiescent~~, 1~~.~~03A on 15W TX~~

	=== DC battery power ===		=== DC battery power ===

	* 2 m ~~repeater: 4.8A on 20W TX (~~repeater drops to ~~medium~~ RF power while ~~on battery power)~~		When running on battery power, the 2 m repeater drops to 20 W RF output. At this power level, it draws 4.8A while transmitting and 0.75A while quiescent.
	* 2 m repeater: 0.75A while quiescent ~~(listening)~~

	* batteries: model 8144, 6-v Deep Discharge (typical Golf Cart type),
	* charger: Foval, charges at 1.0 Ah (so it will take a long time to build back a charge after a long outage) (should this be 1.0 A?)

	~~== Things to acquire for the site (2022-01-15) ==~~

	~~Waterproof documents box (with desiccant packet)~~

	~~12v Fuse Panel, power pole connectors, ala RigRunner)~~

	~~2-RU rackmount panel (to mount the fuse panel)~~

	~~10x24 machine screws, for use in the Chatsworth 2-post racks~~
	~~(In a labeled container, with desiccant)~~

	~~== Info from Andy N7SGV, 2022-01-19 ==~~

	~~Harbor Water is in charge of this stie, and we want to stay on their good side...~~

	~~Herman (?) at Harbor Water got us involved at the site... but Herman is leaving Harbor Water...~~

	~~We can ONLY have PBARC property at the site. (PBARC cannot offer access to non-PBARC gear. (Expect that someone from Harbor Water WILL inspect the shack. All our gear should be labeled!)~~

	~~NO cameras will be allowed on-site. Even asking to discuss cameras is likely to make trouble.~~
	~~(Landowners have extreme privacy concerns. It is a VERY HOT TOPIC~~.)

	~~== Possible Future Equipment At~~ The ~~Site ==~~		The batteries are model 8144 6 V deep cycle batteries, typically used in golf carts. The charge controller (made by Foval) only charges at 1 A, so it will take quite some time to recharge after a power outage.

	~~Fire Radio(s): low-power VHF, antenna ~25' up~~ the ~~tower, with solar panels and batteries, being provided by Andy G.~~		== Things to acquire for the site ==

	~~Water Radio~~(s) ~~will be 900 MHz SCADA data link radios~~, ~~antennas mounted on~~ the ~~top section of the tower.~~		* Waterproof document box with dessicant
			* RigRunner or similar fuse panel
			* 2-RU rack-mount panel (to mount the fuse panel)
			* 10x24 machine screws, for use in the Chatsworth 2-post racks (in a labeled container, with desiccant)
