K2 No Receive on 40 Meters

[KM4VX]

 My K2/10 (#6255) has suddenly lost any receive capability on 40 meters. It transmits on all bands including 40 meters but hears nothing on 40. I have done the simple checks in changing coax and antenna inputs with no change. I have a second K2 for comparison, but lacking any lab equipment here am unable to identify the problem. I don't recall ever accidently transmitting into the rig on 40 when using another radio. Any input from the group would be appreciated. There is no receive on 40 in any mode, just the same low noise throughout the band. The noise level does increase when the preamp is on, but still no receive. It works fine on al other bands. Thanks Ron

  Ron,

Check the menu while you have 40 meters selected.
Is the RX ant set on?  This is a per band setting.

If it receives on other bands, and can transmit on all bands, then this
is about the only thing that can be "wrong".

I want to thank those of you who responded to my problem, and in particular Don (W3FPR) who once again demonstrated his knowledge of the K2 and his willingness to generously share his time and talent. The problem was in the secondary menu. The D19 parameter was "y" and since no K60XV is installed in this K2 the parameter has to be set to "n." Once I changed the parameter to "n" for D19 the radio came to life on 40 meters. I do not know how the parameter might have been changed, but all is well now. I never would have discovered this error without Don's input. Maybe others might benefit from this experience. Thank you all. Ron
