Both units were easy to set up, but the DTVPal was the winner
for me in my testing. The reason:                                     Henry AA9XW

1. Analog pass through
2. More sensitive - picked up stations the Artec did not
3. Has on screen signal strength
4. Graphics more pleasing

So, now you know which unit I favor. Below are some parting
thoughts from Henry, AA9XW:

YOUR COMMUNITY IS IN JEOPARDY
On Feb 17th, 2007 essentially all TV broadcast will be digital ,
except for those thousands of low power stations carrying
some satellite delivered religious or juke box program with no
local input. That means you have likely lost ALL emergency
communication from the TV broadcasters. Check it, all the DTV
sets need AC power. When the AC power goes out, so does
cable TV, satellite TV, over the air TV. All those millions of bat-
tery powered portable TV sets will be worthless. Might
as well toss them in the trash or the ham shack. The few battery
power DTV sets from RS/Best Buy don't have much range, a
lousy direct conversion front end, lots of intermod and other prob-
lems. You can use the USB port on the laptop, provided
you have enough batteries or external emergency power source to
run it for days and a USB port DTV tuner.
