"Bringing class D technology to amateur radio"
 

Index Laboratories  has introduced a new class "D" AM amateur transmitter! Following in the footsteps of the Junior and the Senior, the new SuperSenior lives up to it's name. It's SUPER!

Let's first look at class "D" design. In the past, transmitters in this power category required huge amounts of primary power and produced heat due to inefficiency.  Not so with the SuperSenior. It plugs right into a standard 115 VAC power source and sips it. At full power, with no modulation, the SuperSenior draws under 5 amps.

Audio quality is a hallmark of this class of transmitter and the SuperSenior won't dissappoint you either! The audio is crisp and clear, whether you are using the K7DYY audio processor that mounts in the base of your D-104 or some other external audio processing gear.

The SuperSenior operates on the two most popular AM amateur bands, 160 meters and 80 meters, with full band coverage. You will notice that there is no tuning required when changing frequencies or bands! Simply select your desired operating frequency with the panel switch and LCD readout and you are ready to go.

The new SuperSenior operates at the full legal AM amateur power limit of 375 watts of carrier and will reach 1500 watts peak when fully modulated and it will do this all day and night long! It may surprise you but this all fits in the package shown in the picture, 3.5 inches high, 19 inches wide, and 5 inches deep and weighs almost 10 pounds! 

With the Junior you had to supply crystals for your operating frequency. The Senior included 6 of your selected frequencies. The SuperSenior however has a PLL (VFO) that can be set in 5 khz steps across the both bands.

The SuperSenior has most of what any AM amateur operator could wish for and all in one small package. It even has built in transmit/receive switching to provide convenient and reliable changeovers. Also, the SuperSenior has been designed to protect itself in all but the most abusive situations. All of the transmitter modules are built in die cast boxes and the front panel nomenclature is engraved. It's just pure quality!
