Yes, the TY92 does provide for 16 watts. But it is strictly a 24 volt installation. So no TY91 for me.
Canadian Joy provides sage advice on transmitter wattage ratings. A well designed blade antenna, coax type and connectors and low-impedance ground plane bonding are the most important items for good successful transmit and receive range. Many times it's the receiver sensitivity and audio quality that we as pilots can take on a personal level and in many cases matter more than transmit range. Also, look closely at the fine print on wattage ratings as there are "max" values and RMS values. There can be complications to some of the higher wattage transmitters out there like more distance required between airframe antenna locations and/or splitting locations between top and bottom of airframe to avoid bleed over interference. There will be more EMI in the aircraft for the balance of the components to have to deal with and if the transmitter doesn't have tight performance specifications it can get down right nasty. Imagine being able to check your ammeter by looking at it when you press the PTT and the transmitter whacks your PC680 or EarthX.
So like the Rolling Stones might say, when it comes to transmit watts in the glossy brochures, sometimes it's better to get just what you need and not what you want. Or think you want.
Always go for a quality vs quantity when it comes to comms.
