I think that if you are talking about a K2 by itself, the result will be absolutely nothing. The receiver will be muted for the period of the t-r delay regardless of the setting. However, the amplifier keying output of the K2/100 and (I think) the transceiver t-r switching is based on the 8r line.

So if, for example, you are using the K2 with an external amplifier or transverter that has slowish mechanical relays for t-r switching, you should use the 8r hold option so that you can control the hold time of the external relay with the t-r parameter.

8r normally goes low about 15ms (someone will correct me if this is inaccurate) before the K2 begins to make RF, and goes high again some time after output stops. It can be used to key an external amplifier that has vacuum relays or pin diode switching directly without hot switching.
