Thanks @David.
I'm having problems specifying a frequency using the presetBroadcastStation v1.0 function. If I specify a frequency to store, it is ignored. Even using the sample JSON on the docs webpage.
Whether I specify the frequency, or if I omit the frequency line altogether, it simply stores the frequency that the STR-DN1080 is currently tuned to instead.
This is suits me better actually. But this might confuse other developers as the specification in the documentation (and expected behaviour) works differently for method on this device. The receiver accepts the frequency integer without an error code - and the integer doesn't even need to be in the correct range for it to be accepted.
This should really be mentioned in the method definition in the docs please.
