Like most things in amateur radio, it is
whatever interests the operator and what they find useful and fun to do.

Re: [digitalradio] RE: Re: Too much power and courteous notifiication - how/if

[Jay Budzowski]

Yep, I agree with Jose. Problems with signal width, noise and splatter
aren't usually due to operating high power, but rather because the audio
input to the rig is being overdriven from the soundcard. Until someone comes
up with an easy way to monitor the rf output at the sending station, this
will always be a problem with the soundcard modes. If a high power signal is
properly driven, the only thing it will do is blank out your waterfall,
assuming the front end of your rig can handle the signal that is...73 de Jay

I think it is a matter of signal cleanlinessuse
the lowest power that allows the communication, with a
clean signal.

In PSK, as well as in SSB voice, and many digital
modes with an envelope (I am not referring to constant
envelope modes as RTTY) a clean signal is a must to
conserve bandwidth. It is not a matter of power only.
If you must make the contact, switch on your amplifier
and run it at LOW POWER, that is, low enough to have a
powerful but CLEAN signal with low IMD.

Nevertheless, the audio from your TNC or soundcard
shall never overload your transceiver input. Linearity
shall be mantained from the signal source up to the
antenna, no matter if you run milliwatts or full legal
power.

Happy QSOs,

73 de Jose, CO2JA
