Do you also have a calibration offset for the main oscillator? Ron N6AHA _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/
The purpose of the reflector is not to be a "rah-rah" crowd for Ten Tec. We have brought up legitimate problems and constructive criticisms. You may disagree, and that is your right, but at the end o
I agree. A little PR goes a long way, and it's so easy to do in the Internet age. I don't think anything on this reflector is killing sales judging from the fact that if you order an O2 without the t

Dear folks: I have posted a new graph on my webpage showing the TX frequency response of the Orion II v. 2.032, which now includes the AM response. It looks a lot prettier since I used Excel's powerf
The standard methodology is to use a fixed output, in this case 20 Watts at 1 kHz, then adjust the attenuator on the signal generator to maintain the 20 Watt output. For AM, I used a Spectrum Analyze
The 870 has excellent audio, but the receiver is mediocre. Pre-equalizing a even several dB won't introduce distortion due to the input and AGC characteristics of the SSM2166 mic preamp IC. But the b
I have also noticed similar types of bugs in the O2, including one I occasionally see where two antennas get selected at once. Changing bands fixes the problem, and I haven't considered it serious si
I saw the earlier post about the amp, but have they released any specs yet other than the power and frequency coverage? Ron N6AHA _______________________________________________ TenTec mailing list T
That's good to know...I'll add that to my list of "Things to Fix" on my website. Ron Castro Chief Technical Officer Results Radio, LLC _______________________________________________ TenTec mailing l
I ran the SSB frequency response yesterday on v. 2.033 and found it to be identical to the previous tests with the settings at BW=3900, LF Cut-off=50, EQ=0. The EQ level calibration appeared to be mo
I'm always happy to share my thoughts :-) The O2's low-end drop off (-12 dB @ 100 Hz and -15 dB @ 50 Hz) can be mitigated by using an external EQ, such as the W2IHY 8-Band, which is what I use. The a
I noticed low power when I first tried AM in the new version, but after a few minutes it popped back up. Another odd thing is that it operates different on 10 meters than on 75. I checked it briefly
I'll bet you would be happier if your S-meter wasn't off by 12 to 22 dB, the Notch and Auto Notch worked the way the TT webpage says it should, the monitor worked on AM, the NR worked the way it did
The issue of not being able to adjust the AM power is a problem since most modern amps run 1500 Watts out for 55 Watts in. Since AM PEP = 4 x carrier power, 13 Watts carrier is the most drive you sho
The website and advertising brochure don't say anything about being a "DX'ers radio". Here's what they do say: "The Ten-Tec Orion II represents an entirely new concept in high-performance HF transcei

Not heard on my unit, but you should check to see if it's power supply related, or possibly being generated from some other equipment, such as computers that can be getting into the rig via the power
