Marty -
True.... I tend to think in terms of CW!! :-)
For tuning up the linear or for CW, the Carrier control works fine. If you just "have to" work SSB, you can either rely on the linear ALC, reduce the Mic Gain for the proper scope display, or adjust the TR-7 ALC control (bottom of the cabinet) to the max level required by the linear.
I guess I'd opt to get the linear ALC set up properly.

My impression is the front panel power control is for carrier control and does not work well as a power control for ssb?

But it's very easily adjusted to exactly what's needed by a front panel
control.

The 140 watt output of the TR-7 is kind of high for the SB-200...

John -
The TR-7 uses a "real" relay, and should be able to key the SB-200 easily. The relay is similar to the one used in the 4 Series and the contacts are rated at 3A maximum and 1000V breakdown. The problem is with the (primarily) Japanese rigs that use small reed relays for amplifier keying.

Is anyone using this combination?
I wonder if it's advisable to use an external relay to control the amp, or whether the TR7 switching can handle it as-is?
Sage advice of the Drakelist greatly appreciated!!! John
