On my Orion, I measured the following isolation between antenna ports 1 and 2. I fed Antenna port 1 with an HP generator with a calibrated attenuator. I set the signal at S9. Then I switched to Anten
For Sale: Orion Model 565AT with antenna tuner. Very clean. 1.8 kHz and 500 Hz filters along with the original 20, 6, 2.4, and 1 kHz filters. Heil Studio One microphone and SB-1 boom. Mic has some pa
Does anyone have BeaconSee set up to talk to an Orion? If so I would like a copy of the interface setup or at least information about how to send the cr character to the Orion from the BeaconSee radi
It is my opinion that Carl gives this group extremely well thought out advice. But I think his comment quoted below needs some clarification. As a KH7 prefix call I sometimes end up on the receiving
It seems that a lot of people confuse noise Blanking and Noise Rejection. NOISE BLANKER (NB) My NB is extremely effective on ignition noise and my neighbor's weed eating electric fence. The S9+ fence
I have switched my Orion from version 2.056 back to 1.373b5 because of my perception that the older version NR works much better on SSB in helping to make weak signals more intelligible. I would go b
Put me in the I love my Orion camp because it has the best receiver I can get. I never thought I would get sucked into the AM discussion. But I hooked up the dummy load, 2 different power meters in s
Thank you Grant for the excellent table comparing the NR performance in the V1.37x and v2 firmware. I was in the process of deciding which version of 1.37x to return to. I do not have the luxury of a
If price were no object, I would buy both, put an equal amount into the antenna system and hire someone to maintain the property so I could spend all my time experimenting and on the air. If I merely
With my Orion 2.054 upgrade, the headphone audio can be reliably killed by the following procedure. Place the sub receiver in AM mode. Make sure T and R are on the main vfo, any frequency, any mode.
I guess I do not know what the problem is. Most of the data shown so far do not say if Sub is connected to the ANT or not. My data is consistent with expectations and I also get similar data using bo
Lets not forget that if the strong signal is on one side you can sneak up on him using pass band tuning and the very sharp skirt of the 1 kHz. filter combined with the DSP filter with the optimal ban
I was told by TenTec to contact Heil when I had this problem last year. My original microphone purchased with my Orion, was replaced by Heil in November 2003 because of the same paint problem. Now th
John, Thank you for your comment. I was using the OMNI VI(option 3) and a/b tested it significantly with the K2. For the record the OMNI was better than my prior radios. I have carefully evaluated th
Hi Mark, Glad to see that you got an Orion and are putting it through it's paces. Mine came in the first round and I have noted many of the same things you have encountered. I assume you are using th
I have an original manual on the way. Thanks to all who responded to my request. I had several responses within a few minutes of my posting. Wow! Mahalo, John KH7T
This silliness about evaluating a receiver with an unterminated (infinite impedance) input has gone far enough. Why do I care about garbage that may be picked up with an unterminated front end on a t
I found that on my OMNI VI + mod 3, I was easily able to hear a beat note between the TCXO and the carrier of 10 MHz WWV. I used Spectrogram to sort things out and make sure that I was beating to the
Jim, OUCH! True but nasty. George will now have to try to recover. Watch out. I think an interesting alternative approach is a Tayloe quadrature mixer direct to the A/D and DSP. It seems to have exce
