Hello I apologize for the newbie question. But I would like to verify with a couple things before I complete any connections between the equipment. This is my first HF Amplifier. I would like to pair the Yaesu FT-2000 to the Ameritron AL-811H so the radio will engage the keying circuit in the amplifier. I have read some post that say only a simple RCA Style audio cable is needed. But I would like to confirm which connection on the rear of the Yaesu FT-2000 connects to the "relay" port on the AL-811H. In the Yaesu manual: The TX/RX switching in the linear amplifier is con-trolled by switching components in the transceiver. The relay circuit of the FT-2000 used for this switching is capable of switching AC voltage of 100 Volts at up to 300 mA, or DC voltages or 60 V at 200 mA or 30 V at up to 1 Amp. In order to engage the switching relay, use Menu item “146 tGEn ETX-GND;” set this Menu item to “EnA (Enable)” to activate the amplifier switch- ing relay. The specified range for ALC voltage to be used with the FT-2000 is 0 to -4 Volts DC. The Ameritron AL-811h manual: Use shielded audio type cable with standard male phono plugs to connect the RELAY jack on the AL-811H to the exciter's normally-open amplifier keying circuit. The keying circuit in the AL-811H has a positive 12 VDC open circuit and it provides 100mA of current when connected to ground. The AL-811H has an internal back-pulse can celing diode across the relay coil. Would this be correct to connect the FT-2000 13.8v RCA Phono connector to the relay connection on the AL-811h? I know it's a basic question, but I want to be sure I'm doing everything correctly. Thanks so much for the help.
