Regarding "heavy gauge wire", I suggest one measure the voltage drop
using a DVM connected direct between the power supply Pos terminal and
the radio Pos terminal. Likewise do the same for the Neg DC line.
Put the radio in CW mode and close the key for rated output. If one
finds more than 0.25 volts drop in either the Pos or Neg line, I'd say
that attention to the power cable and connectors would be in order.
Also measure between radio ground and power supply ground. Again a
voltage value greater than 0.25 volts indicates attention to the power
distribution system and station equipment grounding is needed.

Another vote for the Astron Power Supplies they work well.
Use the shortest run between the PS and radio you can and of a heavy
gauge wire.
