The 10-80P is an HF portable antenna system for use within the range of 3.5Mhz -30Mhz continuous! Will work with any HF transceiver, and can handle up to 250 watts PEP! Very simple to use! There is no need for “screw on” type taps like on other portable antennas, this one will tune up and down the band with ease! Also, this one covers 80 meters! Most other portable antennas out there do not. Just listen for the most background noise in your RX, then fine tune with your SWR meter or analyzer. This system is designed to fit any standard tripod with a 1/4 x 20 thread base. You can also use any standard mobile or portable type mount with the 3/8 x 24 thread hardware. Comes with brass whip sections (not flimsy telescopic whip), tripod bracket, counterpoise wire, tap ring and coil. www.pcssales.net

This video shows how I made my 6 meter portable dipole using collapsible antennas and PVC. I used a MFJ269 to do SWR testing. To center the hex coupler nut and to keep the epoxy cement contained I used a rubber grommet around the coupler nut. A length of 51 to 52 inches per side will enable a usable SWR over the entire 6 meter band. Now if the band will just open up so I can try JT65 mode on it. 73, N7JFP

Don CE3FLO, y estimados colegas y amigos. Gracias a dios varias han sido ya las satisfacciones del equipo después de la reparación, la antena que me prestara Ricardo (CA3PRR) y que fabricara don Nélson Lepe (CE3LLP) no ha dejado de sorprenderme y darme una infinidad de satisfacciones por su excelente rendimiento, en las artesanales condiciones en que la tengo instalada. Posterior a la modificación para medios digitales he ido aprendiendo a conocer las características del software flDigi corriendo sobre Ubuntu “Natty Narwhal”, el programa es realmente excelente y no sólo reúne una destacada cantidad de modos y protocolos, sino que también integra control vía CAT increíblemente valioso para ser usado en Contest, cuenta con verificación de características en la Web, y cuenta con un “Libro de guardia” el que registra localmente y en la web los comunicados realizados.

Per Enge [Professor of Aeronautics and Astronautics, Stanford University] Abstract: These days, GPS is used by all of us, and our application space is partially spanned by the following far-flung examples. Several hundred million GPS chip sets were shipped as part of cell phones last year, where they added about to the bill or materials. These will support consumer applications like location specific advertising. The same chip sets will save lives when associated with an emergency call from a distressed citizen. In addition, GPS is included in every new Boeing or Airbus jet, and these receivers cost over 000 each. The cost is dominated by the non-recurring cost associated with certifying a receiver for navigation at night or in bad weather. These GPS applications include location transactions of high value. The value may be economic or safety related. As this trend continues, the conspicuous vulnerabilities of GPS become more important. The GPS signals originate in medium earth orbits. After they have completed their 20000 kilometer journey to Earth, they have a received signal power of approximately 10^(-16) Watts (-160 dBW). These signals can be readily overwhelmed by inband transmissions from terrestrial sources. This radio frequency interference (RFI) can be scheduled (for military testing), accidental (eg harmonics from broadcast television), or malevolent. Malevolent RFI is also known as jamming and is routine for the modern car thief. GPS signals can also be …
Problem manifest itself in the moment after you release push to talk button and station don’t stop to transmitting. This is specifically for 2 meters band and not for 70 centimeters. You can see interesting videos on Youtube how to fix it with soldering capacitor on switch in the microphone housing. This is pretty good solution. I’ll explain why the problem exist and how to fix it on easier way if you are not so good friend with soldering iron. Explanation is easy if you know something about antennas. So, the problem is with RF (radio frequency interference). Why? The length of cable between headset connector and microphone/switch enclosure is 1 meter. In this cable you have one wire for ground, one wire for PTT button, one wire for microphone and one wire for speaker. So when you look two wires – ground and PTT you get beautiful full wave antenna for 2 meter band. You start transmitting and radio waves keep to make noises which radio use like the PTT button is pressed. One solution is to solder capacitor to switch in mic enclosure to change resonant frequency of (headset) wire antenna. Another way is to attenuate RF interference with feritte choke. Putting ferrite choke is noninvasive and pretty cheap solution. Thanks for watching! 73 Tom, 9A5TOM

I was messing around with my Arduino board and figured out how to make a cheap portable electromagnetic field (EMF) detector. It only requires a led, 3300000 Ohm resistor, and wire. As I approach an EMF the led gets brighter, so I can locate the source. Messing around with the code and resistor values I can change the sensitivity of the device; when I first made the EMF detector I could only find one place to stand in my apt where it didnt go off. I am working on getting a commercial EMF detector that spits out quantitative values so I can calibrate my version and have it do the same on a LCD. *UPDATE you can decrease the sensitivity of the device by making a loop with the antenna. Also the code can be found on my website, aaronalai.com
