I didn't notice the option to attach files to the post the first time 'round, but have done so now.
A wav file? What are we supposed to do with a wav file?
The best way to figure out what is being sent is to get one of the sensors, like a temperature sensor and capture what it sends .You will have to pull it apart and sample the data on the data pin of the Transmitter Module.The benefit of looking at the transmitted data is that it gets rid of all the other signals and interferance that confuses what you are seeing.
Is it possible that the device is looking for a response from the base controller first? or that the data is at a rate beyond the capacity of the sound card. For example the data you read might well be a preamble or ID for the base station to identify and or lock on to the remote (dotting) before the data payload and that your method of saving it and analyzing it are missing the data payload?Bob
This is a sample of the data stream of an Oregon Scientific Weather station temp Sensor.Whilst your Weather Station wont be the same , the data format will be similar.The timebase on your audio card is far to slow to see anything sensible, and what you are seeing is the normal outputof an ASK receiver with no input, ie broadband noise converted into random rate data.You need a CRO so you can edge trigger the CRO on the rising edge of the first data byte from your transmitter.

Is this a site problem or a .wav filetype problem?
I recently broke the screen on my Maxkon Weather Station
You will find that your Maxkon is a rebadged WH-1081 from Fine Offset
