This rig is the best CW rig I've owned. It has the Ten Tec 500 hz 900 Mhz, the 500 Hz 6.3 Mhz, the 250 Hz 6.3 Mhz and the 1.8 Hz 6.3 Mhz filters, plus the Inrad 753 400 Hz and the Inrad 600 Hz filters. This rig will pull almost anything out of the noise. I live on a small city lot and only use a tribander at 40 feet, and a 450 Ohm center fed zepp. I have 295 DXCC countries worked and 289 confirmed all with 100 watts or less. For the money and a older rig it can hold it's own with almost any of today's rigs. Wonderful QSK operation and easy to operate, don't need to go to school to set down and operate it.
