I would like to visit your Yahoo Group as soon as I
ask what would probably seem like a dumb question since the cw mode is considered antiquated aparently by most hams.
I wish I knew the secret to recruitment of members as
I had none in over three years to my yahoo group for hams with antenna restrictions.
I know a little about packet as I can also hear the
packet bursts (eeeesspflump) on 144.39, but... If I hook an iambic keyer to an analogue to digital a/d converter then to the mic input of a digital handie talkie,,, assuming we are not talking about packet and a continuace "data stream is present",, can I further filter the rf waveform to a very narrow band signal?
Although I know that the receiver of an ssb or cw rig
determines the bandwith to as little as 50 hertz or less (especially using dsp)the transmitter can
be as wide as 50 khz or even am,, what is the slowest clocking speed I can hook up (externally) to the handie talkie to make the output very narrow? and what speed would I have to send (I rarely send over 12 wpm anyway)
would the speed say over 20 wpm have any effect on the bandwidth?
This would be very usefull to the paying members of my club (a little plug there) as even a 1 watt cw or ssb signal can be picked up on antequated consumer electronics equipment.
What is the bandwidth of a packet signal and what typically is the effect on consumer electronics equipment? I know if I send a very fast burst of cw
say 20-35 wpm every five minutes or so,, my neighbors
poorly shielded tv will cause him to have a fit!
