We've been enjoying "AGC Treshold" for many decades, although we didn't use the name until the recent marketing breakthroughs :-) AGC threshold determines the point above which AGC loop is operationa
This is true. It's certainly better to have a separate AGC threshold, as in Orion. Unfortunately, AGC Threshold control on Orion is an ergonomic disaster. It should have had a knob assigned to itself
That's exactly too much for me :-) I'm not sure either, just a though that it's position should be indicated in relation to signal levels presented on the S meter. Those 5-digit microvolts (with ~1 d
Orion's AGC Threshold control is useful for avoiding AGC action on noise peaks. Such an action tends to intermodulate a weak signal with noise, significantly reducing readability. The same benefit wa

My post appears in the archive: http://lists.contesting.com/archives/html/TenTec/2004-02/msg00845.html but I didn't get it by email. This happened once before. Why? Length or contents? 73, Sinisa YT1
A six-page PDF file (40 KB) titled "USING ORION'S RECEIVER" is available for download from my web site: http://www.geocities.com/va3ttn Topics covered include: * initial adjustments, * setting the op
It was my pleasure. I took advantage of the fact that AGC THRESHOLD does not affect signal to noise ratio significantly and specified 15 dB to be on the safe side. "Exact" noise level is difficult to
I'm glad you like it, thanks. Thanks for the information, I'll add a reference to Spectrogram and a link to Electraft's page. Well, I simply took them out and used a network analyzer :-) 73, Sinisa Y
There are three DACs (called Left DAC, Right DAC and Speaker DAC) generating three audio voltages which are then fed to headphone and speaker amplifiers and LINE OUT, LEFT AUX and RIGHT AUX outputs.
This is a sad fact. And this is an educated guess :-) 73, Sinisa YT1NT, VA3TTN _______________________________________________ Orion mailing list Orion@contesting.com http://lists.contesting.com/mail
What would be the recommended firmware version for this weekend's WAE CW contest? I was too busy for some months and couldn't follow/test current versions. Going to YT6A's hilltop location on the Adr
The AGC Threshold setting certainly determines the point at which AGC action begins to attenuate the signal. But, for convenience, the gain is changed simultaneously, preventing volume changes for si
When AGC Threshold is increased, gain is immediately reduced in the same proportion. No automatic action here, and AGC never "tries" to do anything else apart from maintaining constant volume. There
I did some measurements recently and it seems that SWEEP hardware takes a single 4 ms sample every 2 seconds. This represents 0.2 % chance of hitting upon a short (intermittent) signal, and 99.8 % ch
It is true that some parts of Orion are not protected particularly well against RF currents. These include front panel, CPU, DSP, codecs and audio amplifiers. However, your choice of antenna is, I be

Orion's outputs are open-collector, no voltage is sourced. 1.4 V comes from the band decoder, not from Orion. For reliable operation pull up resistors should be added. 73, Sinisa YT1NT, VE3EA YU DX C
Zero or not, it is the same concept of beating and frequences can be compared to well below 1 Hz that way. 73, Sinisa YT1NT, VE3EA _______________________________________________ Orion mailing list O
