sub file for a Westek pair of Wireless Plug-in Receiver (Model 805) and Wall Switch Transmitter (RFA108), marked with a Channel Code B sticker.
I had difficulty getting a clear reading of this signal.
FCC documentation, page 14 of 16 indicates it's operating frequency is 305Mhz.

The Flipper was able to get several reads at different frequencies (and annoyingly, the Frequency Analyzer really only detects anything at 915Mhz, which must be a harmonic).
So, here was the way to get this to work. Get a successful reading on any frequency that it picks up on. You're looking for a Holtek_HT12X 12b (not CAME). Save it as a sub. This switch has two buttons, but they send out the same button/key code, so you only need one sample.
Open the sub on your computer and change the frequency to Frequency: 305000000
Save the sub and place back on the Flipper. This worked immediately.
The sub attached is from the procedure above. Note that this pair operates on Channel Code B. I do not have any other pairs to test.
