Radio transmission has been one of the most amazing invention man has made. It transmits the audio signals through carriers using atmosphere as a medium. Electromagnetic waves are used for this purpose. These waves are detected and received by the antenna. Later the radio device reads the signal and converts it back into sounds. Though the entire process looks simple, it has been an incredible thought. The success of the radio transmission lies in the signal detection. The antenna will receive the signal from the FM stations which are in proximity. Thus reception is one of the most important thing in radio functioning. This article will brief you on how to boost FM radio reception.

CONATEL (the Haitian Telecomm regulator) has set up temporary offices and released a public notice. Amateurs wishing to operate in Haiti to assist with disaster relief need to contact CONATEL to get formal reciprocal operating clearance. The text of the CONATEL public notice is as follows: CONATEL NOTICE The National Council of Telecommunications (CONATEL) hereby notifies the general public, and those particularly impacted, that following the widespread damage caused by the violent earthquake of January 12, 2010, a satellite office of CONATEL was installed at Number 97 of the Avenue Panaméricaine in Pétion-Ville with the goal of assuring the continuity of its work. This arrangement will allow, among other things, better coordination for establishing a temporary emergency telecommunications network in Haiti. Consequently, all concerned are asked to contact CONATEL at the above mentioned address between 9 AM and 1 PM and throughout the day at the following telephone numbers: (509) 3454-0541, (509) 2516-0000 or (509) 3702-1414, or at these e-mail addresses : This e-mail address is being protected from spambots. You need JavaScript enabled to view it or This e-mail address is being protected from spambots. You need JavaScript enabled to view it , before any use of telecommunications equipment or the spectrum resources. We hope to avoid interference problems and possible conflicts between the incumbent operators established in Haiti and those who are newly operating in this unusual circumstance. The National Council of Telecommunications (CONATEL), while thanking the telecommunications service providers for all their efforts to keep their networks operational despite the widespread damage that has been noted, takes this opportunity to offer its sympathies to the families of the victims of the earthquake.

Even though the communications infrastructure in earthquake-ravaged Haiti is being rebuilt, there is still need for Amateur Radio communications. To assist in this effort, the ARRL's Ham-Aid program is providing equipment for local amateurs to use.
 
In the days following the recent earthquakes in Haiti, the ARRL has received reports and inquiries about non-amateur stations transmitting on several amateur frequencies when assisting with disaster relief efforts in Haiti. The questions focus on the legality of such operations on the amateur bands.

A steady stream of sunspot activity continues to dot the Sun. We had just one day with a daily sunspot number of 0 this week -- January 19 (Tuesday) when sunspot group 1040 moved over the horizon. But the next day, old sunspot group 1039 re-emerged as 1041, and it now graces the Sun's southeast (lower left, relative to our view from Earth) quadrant. In fact, now that we have a view of most of the Sun (87.35 percent -- as of 2359 UTC today -- because of advanced orbiting instruments), it appears that the sunspot group that just left is nearly antipodal to the current visible spot, just exiting the Sun's northwest quadrant. If they stay strong, when the current one leaves, the other should return.

P49Y Holds ARRL SSB Lead; VY2ZM Tops US, Canada
As more scores trickle in for the 2009 ARRL DX SSB Contest, there could be a series of double wins that emerge from this year's contest. In the single operator ranks, P49Y (AE6Y) remains on top, with many expecting P40A (KK9A) to be the top low power entry again this year. Meanwhile in the multi-op ranks, it looks like W3LPL has won the Multi-Multi crown in both ARRL CW and SSB, and that WE3C will do the same in Multi-Two this year.
