BTW Sidney- If you are using the K1 you bought from me, keep in mind it has the KAT1 internal tuner. There should generally be no need to use the T1 with it. If you -do- use the T1, remember to put the internal tuner in the K1 in CLS or CLP mode. See page 11 of the KAT1 manual I provided. 73, Bruce, N1RX
