Please help a newbie: what is SSB packet?
I am guessing data in one sideband with 2.5 KHz bandwidth or so?
I still confuse PSK and packet.

Jawod-

For practical purposes, SSB and FSK Packet are the same, just different
ways of generating the signal.

If you have an RF carrier and shift the frequency, you are switching
between Mark and Space frequencies. A typical Packet TNC also puts out
audio tones that can be used to drive the microphone circuit of an SSB
transmitter. The resulting signal is equal in frequency to the carrier
plus (or minus) the Mark and Space audio tones.

If you tune your SSB receiver to decode an incoming Packet signal, your
transmitted Mark and Space freqencies should line-up with the received
frequencies. However Mark and Space may be reversed. If it won't decode,
switching to the opposite sideband and retuning should clear it up.
