Default If you had to use CW to save someone's life, would that person die?

I would like to add that DXing isn't limited to chasing awards. Some people
just like to find someone in a foreign country to ragchew with. One day I
was lucky enough to come across a gentleman in Italy who simply wanted to
talk not run a pileup. We spent about 1/2 an hour just chatting.

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. [SSB = Single Side Band]

As long a 'Rare DX' uses CW, CW will live and thrive in the DX
community.

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,
