To you happy Orion users Can anyone tell me what extra Ten-Tec filters are required for the stock Orion? I am interested in the rig, but don't know if any of the crystal filters used in the OMNI 6 se

Don, I don't have an Orion yet, but my understanding is that the 6 MHz filters from the Omni V and VI are the ones used in the Orion. In fact, when I do get my Orion, I'm planning on moving those fro

This raises an intersesting question. Given that these filters are now used as roofing filters rather than as IF filters, will the Inrad 400 Hz filter work properly when the Orion is expecting a TT

Well, personally, I think the Orion's optional filters are about as useful as painting the Painted Desert. Everyone to their own taste, and mine's loaded up - but.... My experience with JA DSP's did

Carl, I've had cascaded 250 Hz filters in my MP for over 6 years and I find I seldom use them. 250 Hz is too narrow, especially in contests, because you will miss many guys who call +/- 500 Hz from y

Bill, The Orion DSP filters are NOT audio DSP filters. They are IF DSP filters with the 100 db of AGC action in the DSP alone. They are much better than anything else out there. Carl Moreschi N4PY Fr

I would think it depends how you define audio. In my thinking audio is what comes out of the speaker. Anything before that is IF/RF. John N1JM I beg to differ Carl...from page 52 of the Orion manual:

Bill, Carl is correct. The 14 kHz analogue IF signal enters the ADC, which converts it into a digital bitstream. The DSP processes this bitstream according to algorithms stored in firmware; one of th

This discussion of semantics is missing the point. The point of this discussion was at what frequency/IF stage the DSP filter operates. The Orion/Main RX has 3 IF's at 9 MHz, 450 kHz and 14 kHz. My p

Well, I think you guys are both right. The DSP operates ahead of the audio stage, and thus can be called IF. Of course, the frequency of 14 khz is certainly in the audio range. And no - we could neve
