[TenTec] Eagle & Heath SB-200 Amp

[Bob McGraw K4TAX]

WOAH!    STOP!    If the amp has not been modified for the KEY circuit, 
it has 120 volts on the center pin of the RCA connector.   If this is 
connected to the Eagle it will immediately destroy the Eagle PTT Amp 
control circuit.

The amp relay must be changed to a 12 volt relay and other circuit 
modifications done,  OR you must use an Amp Interface between the radio 
and the amp.

Who ever gave you the information DOES NOT know what they are talking 
about.   This is normal for most hams unless they have actually 
interfaced the SB-200 to the Eagle.    MFJ did make an interface 
suitable for the application.

As Will Rogers said: "it's not what people know that concerns me, it is 
what they know that is not correct that gives me concerns".

If you need additional information, I'll be glad to assist.

> I’ve never dealt with an Amplifier before. A friend gave me a Heath SB-200. It appears I have to make a connection between the AMP KEY terminal of the ACC-1 accessory connector and the AMP KEY Socket of the amp. A plug for the socket and short jumper wire were included with my Eagle. This appears to be all that is needed. I’ll connect from the Eagle to the Amp then through my Antenna Tuner to the Antenna. Does this seem OK?
