Product Description
Put some new "ears" on your rig with one of these hot little preamp kits. Their high gain combined with low noise will improve most any receiver. Fully protected against overload and designed for low current and stable operation they employ high Q tuned circuits which restrict out-of-band signals which can cause intermod blanking and overload of your radio's front-end. Don't be misled by GaAs FET claims! The cheap dual-gate FETs (manufactured for TV tuner usage!) used by others just don't come close to the performance of these preamps designed with NEC microwave transistor devices. Gain is typically 16 to 20 dB and noise figure is 1 dB @ 2 Meters, 1.2 dB @ 220 MHz, and 1.4 dB @ 440 MHz. Compact design for easy installation into most any rig. Operates on 12 to 15 VDC . Size: 1" x 3/8" x 1 1/2".

Don't waste your money.......2007-05-21

I bought this phones less than a month ago and had to return it because of numurous problems out of the box. The screen is too small to function well as a touch screen. It constantly froze and had to be rebooted. It would turn off for no reason and sometimes it took 10 to 15 minutes to get it back on. finally it went out (as always with a fully charged battery) and never came back on. I plug it into the wall outlet and still never worked.

The problem is the processor..........2007-04-07

This little wonder has it all: Windows Mobile 5.0, bluetooth, Infrared, WIFI b/g, a decent keyboard, pushmail, MiniSD card slot, decent speakers, plays audio and video, touchscreen, 2 MP camera, Pocket Office. It's the perfect do-it-all device. However it has two major glitches: the screen is very small, and the main processor (TI OMAP850 200Mhz) is just too slow to run the system. Other than that, I would recommend this phone to anybody.

sd port automatically spoiled.............2007-03-05

This is what looked like the best deal for me.... This black wonder had it all.....
I bought a 1gb mini sd card and i plugged it , and.... it worked, lots of storage space for mp3, little videos, and so.....
Sudenly i travel to a coastal city, and next thing i notice is my sd card not working..... must be a little glitch i think so i unplug it and plug it again, and..... nothing since then.... i havent been able to use the sd port. The rest is alright, everything works fine, but no sd port.
Every time i plug the mini sd card, the system hangs, and after some minutes, it acts like there was nothing plugged in.

It was an automatic failure, because i take very good care of everything i own, there were no missuses and it stopped working with no reason....

Maybe it was bad luck, and it was only mine the one marked by destiny to fail, but i warn you anyway.... it is more expensive than other smartphones, and in my case..... not so good.
