[ICOM] Fw: Icom 7600 and Kenwood TL-922A

[Gary Smith]

Thanks, Adam.  This is most helpful.  I agree and will build an external relay.

Thanks again!

Hi Gary,

I would strongly advise the use of an auxiliary keying buffer between the
IC-7600 and the TL-922A. The TL-922A keying line is rated at +120V/80mA, and
has a keying spike. The MOSFET setting on the 7600 (*** not *** the LEAD or
relay setting) may be safe, but I would still be concerned about the spike
from the TL-922A. There is information about keying buffers on the following
page:

Cheers for now, 73,
Adam VA7OJ/AB4OJ

I acquired a Kenwood TL-922A amplifier and am preparing to connect it to my
Icom 

7600.  On the 7600, the "send" connection default setting is 16V, 0.5A DC;
it can also be set to 250V, 200mA using the Mosfet settings.  My problem is
that the "send" on the 7600 connects to the RL Cont Jack on the TL-922A, but
I am not 

sure what voltage setting to use on the 7600.  Does anyone have any
experience with this?  I'd appreciate your input.

Tnx and best 73,

Gary
