Oops... pretty bad with my cut and pasting... The sentence: "This behavior increases the passband attenuation noise during pauses in speech or between CW elements." should have been: The filter incre
Thanks for the clarification. Apparently I know enough to be dangerous ;) _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman
For the 1.xxx code, I was wondering if the DSP was having over-run issues; the time it took the DSP to do all the calculations per sample was longer than the sample period. But I suppose that would h
Bill, W4ZV There is an important difference between the NR filter (Adaptive Predictor with Leaky LMS) and just narrowing the passband with the BW control; the NR will quickly increase attenuation dur
Gary, I'm interested in learning more about this technique. Can you recommend any reference material on the subject? Thanks, Lin WB1AIW _______________________________________________ TenTec mailing
With enough time, I suppose one could decipher very noisy signals. I can see some pale-skinned dude sitting in a CIA lab spenting hours cleaning up a recorded secret message, but what about a more re
Hi Sinisa, Wouldn't ~10ms would do it? Can't say for sure, however, that the latest code even uses this method any more. Lin _______________________________________________ TenTec mailing list TenTec

Wow, some great information has been brought forth here in the last 24 hrs! Thank you, Sinisa and Grant, for taking the time to run those tests and sharing the results with us. They show me that my c
definitely off topic, sorry in advance Have a listen to WU3A's signal, 28.401600. It has a donald duck quality. I can't raise him to let him know... 73, Lin WB1AIW ___________________________________
Hi Grant, Just a thought- I assume you made these measurements with a steady state signal. Well that will be the worst case for a downward expanding type of NR. However, if the carrier was modulated
SUB RX NR (O2 V2.032) is acting up for me. To test, I went to a quiet area (10 meters in this case). Set up: Rf gain = 100, USB, BW = 2400Hz, AGC = Hang 0s, Decay 80dB/s, Threshold 0.37uV, NB off, AN
Hi Ron, What you described is the way I have been using the v2.xxx NR since day one (rcv'd OII 12/29/05). Changing the NR value seems to adjust the amount of expansion, and with the rf gain, the user
Like John, I've seen this bug well before 2.032, actually since I got my O2 late December. Code version was 2.025. I called Ten-Tec and told Paul about it. At that point, he hadn't heard of it before

Hi Randy, Could you describe more of your setup? What was your VFO assignments? (Default is TX = VFO A, RX = VFO A and SUBRX = VFO B. How were you measuring your TX frequency? 73, Lin WB1AIW Randy K4
Orion operators, be careful if you assign TX to VFO B. Like Randy, I also found a TX frequency error, 1500 Hz worth, on my Orion II v2.032. My setup: On 40 meters: Assign TX and SubRX to VFO B. Assig
Hi George, What happens if you use SEND2 or SEND3? Run power at minimum directly into a dummy load. Do you have problems then? 73, Lin WB1AIW _______________________________________________ TenTec ma
Hi Larry, all, a) Not a transmit offset. Only the receiver shifts when in a CW mode. b) There should never be a frequency difference between the output with TUNE pushed and with PTT pushed, regardles
Hi, First, a friendly correction. Remember, VFOs don't have modes. Modes are assign to MAIN RX, SUB RX and, indirectly, to TX. It might be less confusing to post with this in mind. 73, Lin WB1AIW ___
