No elaborate test gear needed for this test. I am right now listening to an SSB signal at 24.948 mhz. On the K2, the signal is barely discernable with the preamp off. With the preamp on, the signal j
Ok, just a quick simple test with the K2. Tuned to 28.6100 mhz with preamp off, no difference in noise with antenna connected or not. With preamp on, there is a very noticeable increase in noise with
Same test with Orion at 28.6 mhz and preamp off. Large difference in background noise with antenna connected verses not connected. The Orion has more than enough overall gain. And by the way, I am at
I had my threshold set to 2 uv on the Orion when I did this in order to not get any AGC action with no antenna. If I put the threshold at 0.37 uv, then the DSP agc action brought up the receiver nois
In my opinion, standard procedure anytime a new firmware version is loaded, is to then do a master reset. That's what I always do. Version 1.369 is really looking good here. Carl Moreschi N4PY Frankl
Just run the Orion "Amp Key" line to your Ameritron's relay or key line, whatever it is called. The Orion is designed to bring up the amp key line early enough to allow the amplifier's antenna relay
The idea of the power reduction feature is to reduce power BEFORE the finals blow. Adding a delay here defeats the purpose of the feature. I don't see the erratic SWR with my pegasus. 73, Carl Moresc
I re-read Mark's post on this subject and did some more SSB experiments, this time with my speech processor turned off. I did indeed now see an erratic SWR on my pegasus. I believe Mark's analysis is
The Pegasus does not have over current protection and as such has a small exposure to an overcurrent situation blowing the finals. And this overcurrent situation would most likely occur with a high S
Mark, Yes, I do think the airpax breakers do a fine job for this application. Carl Moreschi N4PY Franklinton, NC -- Original Message -- From: "Mark Erbaugh" <mark@microenh.com> To: <tentec@contesting
There is no option on the Omni V to turn off the amp relay. This option is only on the Omni VI. I suspect someone has crippled the relay because they didn't like the noise it makes. Inspect the relay
I like to use my wife's hair dryer as a noise source. It has a noise characteristic that is a good one for most noise blankers. Carl Moreschi N4PY Franklinton, NC -- Original Message -- From: "Mark E
The Oiron runs at 57600 baud, 8 bit, no parity, 1 stop bit. Carl Moreschi N4PY Franklinton, NC -- Original Message -- From: <HeathlinerSB@aol.com> To: <tentec@contesting.com> Cc: <orion@contesting.co
My suggestion is to not use sweep when transmitting. And maybe even don't use sweep at all. Carl Moreschi N4PY Franklinton, NC -- Original Message -- From: "Richard Detweiler" <rdetweil@hotmail.com>
The DSP filters on the Orion are much sharper than the roofing filters. You just set your roofing filters on "auto" and let the Orion firmware handle them. It will pick the best one for you. Carl Mor
Paul, My Orion also had a fuzzy sidetone only in the headphones and never on the speaker. I found when I put on firmware verison 1.367, the sidetone was sometimes OK in the headphones and somtimes fu
Sinisa, Great document about how to adjust the Orion. Very well done. I have one comment I disagree with it. The AGC threshold adjustment on the Orion is actually the point where DSP gain is added to
I concur about AGC. It is supposed to be automatic and not manual. I use medium or slow AGC for CW and SSB reception. I ALWAYS run my agc threshold at 0.37 uv and RF gain full. I cannot find any exam
I've tried this test many times. I do not hear the weak signal distortion with an AGC decay time of 20db/sec and a hang time of 0.35 and a threshold of 0.37 uv. These values work very well for me for
