Hey Bob, Before you throw in the towel, check and check again that the sub receiver AF gain (RF gain too, to be doubly sure) is turned completely down. As an alternative, recommended at this point, i
Ron and all, Here's my findings for my Orion II. I notice that your meter is more generous by 10 to 13 dB! This table shows the input power needed to obtain the following Orion II S-Meter readings us
I also have the white dot next to the STEP value on my Orion II (2.030) using COLOR 3. I also have a rare problem with audio when selecting BinRX=Main (AUDIO Menu) and is related to having NR and/or
John, No problem. The noise that occurs is so loud it hurts my ears when it happens (wearing headphones). I believe that there is a combination or combinations of settings that case the DSP to get a
After reading some some of the comments about the O2 noise blankers, I did this test: O2 settings: AGC: slow (Hang: 2.02 sec, Decay: 5dB/s, Threshold: 0.37uV) F= 21.3MHz, USB, BW=2100hz, PreAmp OFF,
Grant, Rather than being "another very narrow filter", the NR behaves more like an expander type of circuit, implemented in software, with its threshold being slightly above, and adjustable around, t
Hi Grant, Well, I re-read those sections, and have read them many times before, and I stand by what I wrote earlier. I believe there is different NR code for the Orion I (pre-V2) and that is what tha
Well, I did a lot of playing with the NR today and am (stubbornly?) still not convinced that selective spectral filtering are part of the NR function, except for a broad, low pass filter with a varia
I would absolutely *love* to sit down with the software team and talk about all the DSP code modules they used or came up with on their own. For that matter, the hardware team too! So Gary is a good
Hey Lee, I thought about that too. I changed frequency to a different type of signal, such as ssb, turned the NR on then off and reverted to the test signal and turned NR on. 73 Lin _________________

Hi Grant, I've done a bit of research into DSP filtering and even called Gary at Ten-Tec to find out what the NR filter implementation is. And you are correct, it is certainly not just a form of an e
Hi Mertin, Thanks for the excellent suggestion. I took you up on it and more! I agree 100% that we should know the technology behind the functions, if only to be able to better use them. Best 73, Lin
Hi Ron, If you narrow the BW below 200Hz, does the audio level still decrease? Thanks, Lin WB1AIW _______________________________________________ TenTec mailing list TenTec@contesting.com http://list
Sweet! I'll try to get it downloaded later tonight. Thanks, Lin _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/
Hi Bob, I noticed that sometimes I would see something other than 1.0:1 even after adjusting my external antenna tuner for a perfect match (according to the tuner built-in SWR meter) I just ignored i
If I may be so bold as to offer another way in which S+N/N may be improved, albeit with distortion; that is by using non-linear gain. The NR, probably still being some form of Doug Smith's "adaptive
Interesting! I wonder if Ten-Tec did this to reduce the DSP workload thus increasing overall performance (i.e.. sweep, and user input response). If I understand correctly, if you cut the bandwidth th
