panic at main.rs:133:66

I tried with both compiled and with downloaded binaries and got the same result: ``` ./dump1090_rs [-] using soapysdr driver_args: driver=rtlsdr Found Elonics E4000 tuner [INFO] Opening Generic RTL2832U OEM :: 00000001... Found Elonics E4000 tuner [-] using config: Sdr { channel: 0, driver: "rtlsdr", setting: None, gain: [ Gain { key: "TUNER", value: 49.6, }, ], antenna: None, } [-] Writing gain: TUNER = 49.6 [E4K] PLL not locked for 1090000000 Hz! thread 'main' panicked at dump1090_rs/src/main.rs:133:66: called `Result::unwrap()` on an `Err` value: Error { code: Other, message: "setFrequency failed" } note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace ``` The USB SDR is recognized as a RTL2832U by cubic, but cubic also barfs right around 1090, however sigdigger seems to have no trouble at that frequency:  Any hints?
