LimeSDR mini port H dead


my LimeSDR mini has a dead H port, while the W port so far works, but maybe e bit less sensitive. Also the self test loop fails. So I guess the SKY RF switch is defective, what also is a common PITA with USRB B2x0 radios :frowning:

Any ideas who to get this repaired in Europe? Sending this to the US with weeks in transport and customs is not an option. I wonder why it is not possible to construct a SDR that withstands normal usage with the short standard antennas.
