[Icom] New IC-756Pro Problem

Wed, 27 Mar 2002 06:41:35 -0600

The Astron RS-20 is not an adequate power supply for transmitting with the
Icom IC-756Pro .. which draws approximately 22 to 23 amps during transmit.
The Astron supply is only rated at 16 amps (continuous) and 20 amps (ICS).

Also have Mike check to see if he has the "timer" activated.  The red LED
will be lit on the 756Pro power supply switch (upper left corner of rig)
......

Lastly, stray RF can shut down some 120 VAC to 12 VDC power supplies (most
notably the switching power supplies)
