If you had to use CW to save someone's life, would that persondie?
Example.
A few months ago a group of ham radio operators went into the central Pacific Ocean to an island named Swain's Island [ATOLL]. Swain's Island had just been approved by the Ham radio Certificate Powers {American Radio relay League] as a separate DX [distance] entity and as such it qualifies as an entry into the various DX awards [DXCC being the prime award}. [DXCC means you have submitted written proof of confirmed contacts with other ham radio operators in 100 or more other countries [or entities]. The Hams operated from this rare location for about a week and then returned home. There is no-one there today! Let me digress into another of your questions: i.e. What is SSB? Fifty years ago ham radio, and still today the AM broadcast band, transmitted three components to put a signal on the air. First, was the carrier that set the dial frequency e.g. 3950 KHz. The carrier contains NO information, it just sets the dial frequency. Then voice audio was added to the carrier. This addition [modulation] produced two audio signals around the carrier. One above the carrier, the other below the carrier. So, the resulting signal had the carrier and one upper side band and one lower sideband. The carrier contained 2X the power of the audio. And the audio was redundant with 1/2 the audio power in each sideband. The resulting signal can be described as Double Sideband Plus Carrier. In the 50s and early 60s design techniques were incorporated to suppress the carrier, which contained NO information; and to eliminate one of the redundant sidebands. The resulting signal is Single Sideband [one audio channel] with suppressed carrier.

I've seen this DX term here and there, but, can't seem to find out what it stand for, or what a DX community is. Can you post some info or links on what this is/involves? well even if you are pulling our chain it is better than a lot of the stuff posted DX isseeking out Distant contacts for an eXchange of very basic data and ocollecting these conacts and esp proof of these conacts for various awadrd the DX comunity obviously is those into chasing down these DX contacts Thanks, noonespecial http://kb9rqz.blogspot.com/ |
