The Orion, like most transceivers, has two CW modes, one an 'upper' and the other a 'lower'. On some radios, they are labeled CW and CW Reverse, but in any case this determines the 'direction' of the
It does not appear to be. I have a 6 Hz difference in the main and sub receivers on all bands. Ron N6AHA _______________________________________________ TenTec mailing list TenTec@contesting.com http
That's the way it is in the Orion II also. I agree with you...I like the other way better. Ron _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.c

Has anyone else noticed that there is some distortion on AM receive on the O2? I hear it on both ham frequencies and on broadcast, especially on voice. It sounds like an the IF being overdriven, alth
Grant and group: I ran a frequency response test on the O2 on AM and found the following (all controls set flat, modulation at 50%, no compression or ALC): 20 -1 dB 30 +1 50 +1 200 +2 400 +1 600 0 10
Where's the antennas??? :~) Maybe stacked MonstIR's on each of two 140' rotating towers and a pair of 4-squares on 80 and 160? Can I put that on my VISA? Ron Castro N6AHA ____________________________
Here are the results of tests on the O2 that I made and sent to Ten Tec: S-Units Standard uV Standard dBm Orion II Pre off Descrep Pre off Orion II Pre on Descrep Pre on S-5 3.16 -97 S-2 -12 dB S-6 6
Whoops...I didn't mean for it to come out like that! Lets try this... Standard Standard Orion II Pre off Orion II Pre on S-Units uV dBm pre off Descrep Pre on Descrep S-5 3.16 -97 -12 dB S-6 6 dB S-7
True enough about S-meters historically being a relative indication. There was a time in late 50's and early 60's when the "S-meter wars" started between the manufacturers, mostly Hallicrafters and H
I think there are adjustment pots in the ADC/DAC, R337 and R340 of the A7 section (schematic 10) that effect the meter, although it may effect the S-Meter reading too. Best check with the factory, bu
I just looked closer and R337 is not adjustable, however R340 is. Ron N6AHA _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailm
List members: A couple of weeks ago I began a series of tests to determine if cooling of the A10 board area of the Orion II would result in increased frequency stability. My first test was to place a
My take on it is that the processing is done in the DSP modulator stage, but there is no clipping. I see very little increase in average output, even at heavy settings, and I don't hear the kind of s
Keeping it on would fix the problem...but I'm sure it would eventually take its toll on component life. I ran across a Peltier device while I was researching this, and very briefly considered pursuin

This is an interesting topic that I deal with regularly in broadcast engineering. The goals are quite a bit different but the way of getting there are similar. You may be surprised to know that many
