[Elecraft] Help needed

[ta2ah]

Hi,



My K2 serial number is 4288 with all options installed, except 100 Watts module.



When Antenna 2 is selected without any antenna connected to it, I push to tune button to try to tune it on 7Mhz band three times. Now there is not any output on 7 Mhz and only 3 watts output on 10 Mhz. 

but receive is OK on bought frequencies.

 

K2 works perfectly on the other bands (I am using SCG 237 antenna coupler when I use it at my home). 

 

How can I correct this? Any comment would be appreciated.
