Hi Randy, I notice here that when you changed TX from VFO A to B, you assumed the TX mode would become the same as the SUB RX mode because it was assigned to VFO B too. My first thought is of course
I have to admit, I gotta chuckle from that... Thanks _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec
Hi Grant, etc, What you say about the "distortion" actually being the noise that had been suppressed until the cw element or ssb signal raised the gain is accurate. There is added distortion, though,
Dream NR: Very similar to Ron's thoughts. I would love if the O's had both DE and a leaky adaptive predictor filter and we could chose one or the other or both and be able to vary each separately. As
Hi Grant, Thanks for the info. Interesting. I respect what you say, and hope that if you find out it what they are truly doing, you let us know. I'll do likewise. I totally agree that with a constant

Hi Ron, Just curious if you have hardware NB on when you experience the artifacts. I haven't put v2.033 on yet. I just had a listen to a 40 meters, about 1 khz above a strong BC, with AN set to 9 and
Hi Lee, When you first power the O2, the ALC LED should come on for a short moment as it powers up. The sequence is 1. S-meter backlight on. 2. S-meter backlight off and all front panel LED's on (inc
Lee, Also, if the O2 is same as O1, then the ALC LED is driven from the same UCN6810 IC as the VFOA SUB RX and VFO B SUB RX button LEDs. (These buttons are shown on page 7 of the Orion II users manua
Hi Dave, If you haven't sold these items already, I'd like to buy them. Thanks, Lin WB1AIW Londonderry _______________________________________________ TenTec mailing list TenTec@contesting.com http:/
Bob, My O2 sidetone also sounds fine, even with 2.037j. Can you record it as a .wav file so we can take a listen?? Lin WB1AIW ps. There is a t/r relay in the rear of the Orion that makes a quiet clic
Hi Kim, Back in the spring, many of us posted here regarding the NR. As Grant suggested, you can check out the archives. There's good (historical?) information there. The manual section regarding NR
Grant, you are soooo right. It raises the hair on the back of my neck ;) You hit it on the head. Doug Smith's NR implementation was an "Adaptive Predictor with Leaky LMS"; an autocorrelation filter.
I'm going to go out on a limb here. The following is based on what I understand about discrete-time filters, and I admit I am not fluent in their design, but may understand the theory enough to post
2.041 Users, Set O2 for AF AGC. Then try setting the AGC to SLOW or PROG, then go into the RX menu and turn the decay rate to less 6dB/s. I found that severe distortion occurs. Further, a decay rate
Here are some findings and opinions with the 2.041XL. I used spectrogram software (Spectrum Lab) to measure/observe aspects of the behavior. 1. When AF AGC is invoked, there is a full 20 dB drop in a
Hi Kim, I just checked on this and found the same behavior as you describe. Lin WB1AIW --Original Message-- _______________________________________________ TenTec mailing list TenTec@contesting.com h
Hello folks, Primarily for the reason below, I've been considering drastically reducing the frequency drift over temperature that my Orion II experiences. So I contacted Abracon Corp to see if they'l
Hi Hank, This won't be a direct swap-out. The replacement is larger, has more pins, and is a surface mounted device. Also, to be adjustable, a trimmer circuit (simple) needs to be added. Wow, that's
Hi Martin, It is electrically trimmed. Here's the trim app note: "http://abracon.com/Support/AOCJY Vref App Note.pdf " and phase plots are here: "http://abracon.com/Precisiontiming/AOCJY Typ Phase No
