WICEN Vic: Portable/Mobile Power Source

Sat Oct 4 22:26:25 CDT 2014

Hi all,
This appeared on the hflink Yahoo group.
I thought it was an interesting article, with a 
lot of information on battery systems, and wire sizes etc.
Its a bit of an Ad. for West Mountain Radio, but 
interesting looking at the gear & prices they have.
For your information.

Thanks
Paul Whitaker.

>The battery handles the load and keeps the amp draw off the PG-40S. The
>20 amp power supply I used to use on a ham rig is feeding the PG-40S
>full time on the base / portable, and it loafs along at just a few amps
>most of the time. Some times five amps if the power was off for a little
>while and the battery drawn down a bit. Even after using the battery
>with out charging for eight hours or so, the charge rate hardly hit 8
>amps. The same can be expected in a mobile setup.

>You can isolate / protect your vehicle / portable battery and the
>equipment attached to it, by using some sort of power isolator. The
>standard RV diode or relay isolation options is NOT enough.
>
>APO3 Timed Switch, kills the power to PG40S after the vehicle is shut
>off to prevent draining / damaging the car battery after a preset period
>of time. Have mine set to zero minutes as a delay is not needed when
>operating off a ham battery inside the vehicle (not the one under the
>hood used to start the vehicle). If you were not using a separate
>battery from the vehicle, and was feeding the ham gear from the vehicle
>battery, then set this to about 10 minutes delay. Keep in mind you will
>have vehicle starting transients applied across the transmitter finals
>before the APO3 times out. Get a bad starter and this can be damaging.
>When the APO3 times out, it also keeps the power off the PG40S / Ham
>radio and equipment during vehicle starting, protecting those systems
>from starting transients.

>Investing in the components for a portable power supply to support all

>supply as commonly used for most 100 watt ham rigs for charging power,
>and a power cord extension, I can charge from any AC source with in
>range for portable and base station operation. AC burps do not take the
>station off the air.

>Several charging cables are made up to tap into most vehicle battery
>systems through their cigarette// lighter outlets, RV trailer hitch
>power connector, and of course common clamp on to every day vehicle
>batteries. Charging current never exceeds 10 amps, and typically is
>around 5 amps during normal operation.

>For information about connectors, this site has a great file of
>information that can be downloaded. Of course your user manual is a good
>source too for the connector pin outs.

>Personal vehicle is prewired with a removable cabling system to

>feeds, power connections and antenna cables. All cables use connectors,
>quick disconnects or power poles for easy assembly / disassemble.
>Antenna mount uses a right angle tube that slides in and out of the
>trailer hitch and held in place / grounded using two heavy duty bolts
>that tread into the right angled tube antenna mount. Antenna mount and
>antenna mast uses a large and heavy duty Quick Disconnect. Capacity
>hat and whips also use quick disconnects. Fast easy changes while on
>the road, including partial / full removal of antenna / mount and
>stored in vehicle. Antenna mount and HiQ5/160 antenna with out
>capacity hat or whip installed, can enter / exit garage. Capacity
>hat and whip is so easy to remove and put on as needed using quick
>disconnects. Spare mike and equipment cables is not a bad idea.
