TK 2238

AC Remote: Carrier AirCon unit
AC Unit: Carrier AirCon unit - 38MPQ2405
Data Bits: 100 bits (206 marks & spaces)
IR receiver: TK 2238 Status: FAIL
Optional Comments: IR receiver extracted from old DVD. The TK in the model name may refer to Telefunken (now Vishay). It appears to be AGC 2 which may not be the best for longer AC infrared signals.

TSOP38238

AC Remote: R11HG/E
AC Unit: CARRIER brand, the model number is 38MPQ2405
Data Bits: 48 + 48 (96)
IR receiver: TSOP348238 Status: FAIL
Optional Comments: User Aldagoni, reports this receiver can receive intermittently for a selection of AC units (Works sometimes, other times not). Although this receiver can work, we classify it as a FAIL, because it does not work consistently and it is classed as a legacy device by the manufacturer Vishay.

A quick reminder: The classifications in this topic/thread are for longer Air Conditioner Infrared remote control signals only.
Most IR receivers will work fine for TVs and other media devices, as long as the modulation frequency matches)
