Using a Drake 2B receiver with a T4/T4X<any> transmitter, the front panel
PASS BAND setting must be in the correct setting otherwise you won't be
on the same Side Band as the station or ground you are wanting to join.
The 2B manual discusses the PASS BAND setting on USB or LSB.

Tune in the station or group so they sound natural in the 2B receiver.
Set the transmitter to SPOT and adjust the VFO so your voice sounds
natural in the 2B receiver as the distant station or group sounds.

Using CW, setting the PASS BAND is the same. Tune in the station and
adjust the PASS BAND (CW is typically in USB) so the tone is how you
want it. Turn on SPOT and adjust the transmitter so the SPOT signal is
the same tone as the distant station. Do NOT adjust the receiver
so the distant station's tone drops to zero, no beat note in the receiver's
speaker. Doing that will result in the distant station not hearing you.
Zero Beat means exactly as it says, the receiver's tuning is adjusted to
the point where the distant stations receive tone frequency decreases
to zero, no beat note heard in the speaker. The typical CW beat note
receiver tuning is 700 to 800hz.

Always allow your transmitter and receiver to warm up for at least 30
minutes.
