I'm selling my Orion 2. It's about 15 months old and in excellent condition. It has the standard roofing filters (6 kHz, 2.4 kHz, 1 kHz) plus the Inrad 500 Hz filter. And the built in antenna tuner. It does not come with a microphone (I didn't throw it away - it comes from the factory that way). $3500 plus shipping. Please reply direct. Thanks. 73, Bud N7CW
