PSK mildlly

overdriven

occupies about

100+ Hz

PSK badly non linear,

occupies 1300 Hz and has

harmonic

and there is a

third harmonic

of the signal

PSK signal at 1450 is ok on drive level

but is creating spurs down every 300 Hz

probably has compression on or bad RF

feedback

Signal at 1000 is

overdriven with multiples

of 31 Hz on either side of

center - about 185 Hz wide

Common Problems & Solutions

•Wide Signal

–

Overdrive of audio on Tx, ALC or Compression on on Tx

• Hum on Signal

–

Needs shielding on cables

–

Common mode noise, use transformers on both channels

–

Ground all system components

• Harmonics of audio carrier

–

ALC on, Compression on

–

Transmitting outside of Tx bandpass

–

Transmitting below 800 Hz audio offset

• Frequency offset between stations

–

RIT is ON, or XIT is ON

–

One of the transmitters has an offset

Common Problems & Solutions

• Signal Cutting In and Out

–

CPU too slow

–

Too many processes running on CPU and active processing

–

VOX is set too close to the signal level

–

Bad connection

• Strange signals mixed with a good psk signal

–

Mute all sources on “Playback” except WAVE

• Sounds from the shack being transmitted, like typing

sounds, telephone ringing, etc.

–

Mike is active

–

Mike on PC is active (Mute it - see above)
