Hi,
I am a newbie and trying to understand CW better. So far, from
whatever I've read, CW is turning on and off the carrier wave. Is it
the same as hitting PTT at particular time intervals?
I have a Yaesu VX7R and I am trying to figure out what is CW *mode*
that this HT lacks? Is it something I can emulate using a computer
connected to the HT that can control PTT and mic?
Please feel free to point me to any basic literature I should be aware
of before I ask such questions.
CW (continuous wave) is used to designate on-off keyed morse code, which
is received by beating the received carrier against a receiver's interlally-generated BFO signal to produce an audible note. Your VX7R is,
I believe, strictly an FM voice radio. You CAN send morse over it if you
can manage to hook an audio oscillator into its microphone input and then
key up the rig and send. This would be MCW, where what is keyed is the modulation tone and not the base carrier.
If you can, get a copy of the ARRL or RSGB handbooks. These usually cver
all of the various aspects of ham radio and should give you some pointers
as to what is feasible. Even ten-year-old handbooks will give you ideas.
