I would suggest you just use your car. The radio will obviously run
off the battery directly. If the laptop's battery voltage is close to
14V you can probably wire up a power cable to go directly to the car

Hi,
This is a project I am currently into. I am passing the
information so it gets recorded somewhere for others, and also
because I have a few information requests.
I have a FT-757GX from the 80s. I just cannot afford what a newer
HF costs. Also I got to like this one :)
It has a

Below are the items I use to power my system, base, mobile or portable.
This extra battery is not part of the vehicle, though the vehicle charges it
when running. Other wise a 15A 13.8 volt ac power supply does the charging

All this sounds more complicated and time
Equipment selection for emergency service can be viewed from many angles,
but in general:, goals need to be defined so selections can be made to fit
the goals:

the least power that does the tasks needed to be done.

Many HF rigs use relays for bandpass filter switching, and other tasks.
Unfortunately when changing bands, these relays cycle to the configuration
needed for each band range. When using software to scan the bands, these
relays are being cycled with each band change request from the software.

There are a variety of challenges in interfacing radios, computers, data
interfaces, cabling interfaces and antennas. All have to be addressed
individually, but sometimes it is hard to make choices when there are so
many choices. Nothing wrong with home brew here Hi Hi

Andy,
From a flat battery you can get all the LED's to come on in around
15-20 minutes of pedaling. It depends on how hard you make the flywheel
spin. You don't have to recharge that way though, only in the field
because you can also plug in a wall wart at home and charge it up
beforehand.
ARRL Introduces Fifth Pillar at Dayton Hamvention®
On Saturday, May 17 at the Dayton Hamvention, ARRL President Joel Harrison,
W5ZN, plans to announce that the League will expand its identity program to
include greater emphasis on technology. Harrison explained that Ham radio
operators, and
Harrison explained that Ham radio operators, and particularly ARRL
members, closely identify with current and emerging radio technology.
Today, we are naming 'technology' as ARRL's new fifth pillar.
No doubt they will inform the amateur community of these intentions in
an ASCII bulletin
Too bad all the potential hams that wanted to hear this 20 years ago are now
top Cell Phone engineers, WiFi Gurus, running Satellite Radio stations,
etc.
Paragraph 4 is the affirmation of this and the effect from the cause. It
could have read that professional technical minds have always

I'll believe it when I see a change in QST that puts more emphasis on
advancing the radio art and less on preserving it.
(Not that I have anything against that, it's just not part of our
purposes - or ARRL's pillar.)
