Satellite Fever KP4WK working AO51 with the tape measure antenna

This is KP4WK working AO-51 using the tape measure antenna designed by WB2HOL. The video speaks for itself. I’m really impresed with the performance of this antenna. Enjoy !

Check My Blog for Detail : blog.siamsq.net I used to buy the kit from HAM which made from PIC Microchip and It was very hard to design on what I want and Now I have Arduino project that I can learn and put more feature and more up to date as this day many people know how to build any Micro Controller by using Arduino which is very powerfull platform base. I already builded and still develop put more feature and using IR funtion. and much more. receive the Control command via serial port. Arduino have too many function that you can play and I gueesed most kid can build Robot in 1 Hour program with Arduino. http

Demo of LD-1B software-defined radio (SDR) hardware with Winrad SDR software. This was recorded around sunset (5:55 PM) local time, 22:55 UTC on 29 December 2010. The antenna was an MFJ Super Hi-Q Loop which tunes 7 MHz – 21 MHZ. The antenna is horizontally mounted at about 25 feet above ground. The soundcard was an E-Mu 0202 sampling at 192 kHz. The demo begins on 20 meters, with the LO set to 14.0625 MHz and the receiver tuned to some PSK-31 signals around 14.07 MHz. Next, some CW signals, first using the SSB filter followed by the CW filter. The display is zoomed in to facilitate tuning with the narrow filter. Back to the SSB filter, and the LO is shifted into the 20 Meter phone band. Next, the AM filter, and WWV at 15 MHz. Next, 40 meter CW, first using the SSB filter, then demonstrating the CW filter’s capability to separate weak signals from nearby strong signals. Finally, a little shortwave broadcast listening in the “tropical band” This is outside the tuning range of the antenna, so signal levels are somewhat lower than one might expect. For more information about the LD-1B, go to www.lazydogengineering.com To order an LD-1B, got to shop.lazydogengineering.com The fluctuations in signal level and some of the buzzing and clicking sounds that are heard intermittently are due to retuning the magnetic loop antenna when the LO frequency is shifted.
