Howard..this verison only supports the 500 kHz frequency. I know there were other models that supported the 8364kHz frequency too. I don't know if one followed the other in time or they both existed during the same time frames. This unit does support manual keying via the button switch in the front panel.

Unfortunately my units only have the basic case and insides. The kite,balloons and lights are not there. But considering I was only wanting the generator initially I'm a happy camper.

That's one for Howard.
