10MHz Ref Clock I/O (BNC), External ATU port, Keyboard In, COM Port (Female 9-pin), Straight Key, Paddle/external Keyer, 2 x USB-A & 1 x USB-B ports, "ACC-2" Data/audio connector, "Remote" linear connector, analogue Meter Jack 3.5 mm, "DRV" low-level LF drive, Optical SP-DIF I/O, 2 x external speaker sockets, DVI-I Dual-link video port, LAN port
The TS-990S’ rear panel incorporates four SO-239 antenna ports plus a receive-only RCA jack. Other sockets include both USB and serial PC connections, external ATU, outputs for two loudspeakers and external signal meters, digital I/O for soundcard programs, a LAN port, a keypad input and a high-res digital video output to display the main LCD on a TV or monitor etc.
LCD Touch Screen Display
The TS-990S incorporates two colour LCDs – the main screen is a 7” TFT display and the sub-screen is 3.5”. The main screen includes a touch-tuning function – just touch a signal peak on the bandscope and the TS-990S instantly retunes to the target frequency.
Digital Signal Processing
Not one, but three Analogue Devices Included. advanced DSP ICs handle ID processing for the main band, the sub-band and the bandscope.
The TS-990S can output up to 200 watts, so its cooling system has been designed to handle the heat generated internally. Five electronically-controlled fans cool different sections of the rig, while a massive heat sink soaks up any thermal load – even its fins have been computer-designed for maximum efficiency!
With down-conversion on all Amateur bands the TS-990S is fitted with five High-IP Roofing Filters. These work in conjunction with the DSP-based final bandpass settings, or can be manually switched too.
Giving you a rare glimpse behind the scenes at Kenwood's Communications Division factory at Yamagata, in northern Japan, this video shows our new flagship Amateur Radio transceiver the TS-990S being built. It's not all robot machines -- real people help to create a masterpiece of communications technology that's rapidly won the hearts of many Amateur operators around the world.
