[1000mp] Question 2nd RX ft 1000mp mark V

[DL3HBY]

Hello Group  - after switching my radio on the audio on the monitor (sub 
band rx) is on the
upper side band too low an on the lower side band too high. (it sounds 
like the carrier offset is not correct but menue 8-9
is only for the main vfo)) The RX frequency of the 2nd RX is ok!
After morming up (perhaps 15 minutes) - the audio is ok, lower an upper 
sideband sound is normal..
Any idea??
