[SCCC] Portable Laptop for Field Use with KX3

[Bruce Horn]

Hi,

Looks like there are 12V to 19V DC-DC converters available for powering laptops. Here's a recent review of one:

Hi David,

I'll be interested in what you learn about laptops. I've heard that some 
will work on "12 V" even though their wall wart makes 18 to charge the 
internal battery.

"Ruggedized" laptops may have brighter screens for use in police cars, 
or in the field. I think a Kindle-type screen would be interesting, 
though too slow for most uses. Maybe as an external display?

Get a USB to Elecraft cable from Elecraft. (I have a spare you could 
try.) It carries the frequency data.

I use a K1EL keyer to key the transmitter. It translates USB 8-bit 
alphanumeric to open collector cw code. Theoretically, fast modern 
computers don't need the K1EL, but then you'd need a USB to RS-232 
converter. See N6TV.
