Transmit drive level for packet using the FT-8800 and KPC-3+.
I did some testing and found the proper drive level TNC setting if you are using the Yaesu FT-8800 transceiver with the KPC-3+ TNC.
Since you will be using 1200 baud mode, be sure the radio menu is set for 1200 packet speed.
The KPC-3+ sets it's drive level from the user menu with a command named XMIT for short.
We want that set at 100.
Type xmit 100 then press enter. That should do it.
You can check by typing just xmit and pressing enter. It should return the new 100 value.
Now the radio will transmit with 3 kHz of deviation when sending packets.
