[Orion] Problem wirh AM mode

[Jim Miller WB5OXQ]

When I try to transmit on AM when the transmitter is first keyed there is little to no power out.  After holding the key down for a few seconds the power slowly begins to increase until it reaches the full power available on AM.  This may take as long as seconds.  So much for trying to break into a conversation.  By the time I have enough power to be heard someone else is already transmitting.  This is true whether using an amplifier or not.  Does anybody have any ideas on what could be wrong?  If I wait for full power to develop I can unkey and re key within a couple of minutes and get full power immediately.  Ver 2.057.
