Just hours later I received a response from K4JU Jack Burchfield, CEO of Ten-Tec: "I understand your problem with the agc and notch and so does Gary." <details snipped> "We have been working on possi
I think that depends on what you call a "big difference." The outstanding performance of the Orion, with close in interfering signals, is largely made possible by the narrow roofing filters ( 1KHz, 6
Gee Ron, now I feel like I have low expectations for the Orion. After having it for 2.5 years, I just want firmware for the Orion that has the functionality of the Orion V1.373B5 (Notch filters that
-No main Rx signal (normal noise, however). Sub Rx is fine on same VFO and same antenna input. No change in main Rx noise with preamp or attenuator settings. Main Rx hears nothing on either antenna i
Grant (NQ5T) did some careful measurement of the performance of the noise reduction in the current V2 (2032?) implementation in the Orion II. Although noise reduction is not the number 1 capability o
A few questions Merle: 1. If the starting point is using the DSP's 100 Hz bandwidth, will enabling NR improve S/N? I don't see that with 1.373b5 and Spectran. 2. If enabling NR makes no improvement i
I went back and confirmed that I was seeing attenuated signals when the receiver was set to 30M and the transmitter was set to 10M (Split mode) and the tuner was disabled...... Please forget all afte
I have had my Orion for a little over two years and have always gotten, unsolicited, really good audio comments I'm not an "audio aficionado" but I do use a W2IHY 8 band equalizer that I got for my Y
"I don't understand, Bob, when I push A>B on my O2 and O1 (1.372b5) band and mode are transferred perfectly." I don't know about the Orion II, but the Orion only transfers the mode when you do A>B if
"This can result in having the transmit mode different then the receive mode." Actually that statement is not correct (See previous post). It can result in the Main mode being different from the SUB
I have been using the Orion for two years and had not noticed this issue - its a function of how you operate. I use the band decoder output from the Orion to drive a Top-Ten band decoder and two remo
TEST: "Orion I with V2.055 set up as follows: MAIN RX on ANT1 and VFO A, 3750 kHz LSB, 6 kHz roofing filter, BW = 2500 Hz, PBT = 0 Hz, 199 taps RF GAIN = 100, PREAMP ON, no ATTN A -79 dBm (S8 dB) car
Sinisa, Your testing, and finding the "spur problem" in the V2 firmware, is a good reminder that most of us don't really validate the performance of the radio with our "limited usage." We may realize
"Just loaded 1.373b5 and it appears the same as 2.055. 73, Sinisa YT1NT, VE3EA" Sinisa, I saw the note that you had seen the "reverse spur" on V1.373b5 so I went back to try the tests again today - B
Lee, I think you must have "low expectations" for a "great contest radio?" With the V2 code display being useless in contesting, the QSK not working over 20WPM, the Notch and Auto-notch filters not r
Larry(N0XB), I don't think I was clear in my note on the "Great Contest Radio," although we might still not agree. I believe the Orion, with the V1 code - I run 1.373b5, is a great radio. I also unde
Carl(N4PY) the Orion is my first TenTec radio so I don't know the history of "specific nomenclature." However, I spent a lot of time with the R-390. I think you forgot to say that the R-390 had a 4KC
"No such luck, two different processors, two sets of code Orion I 16-bit fixed-point; OrionII 32-bit floating point" Ron (K6KDK), The Noise Reduction code runs in the DSP processors. The two DSP proc
Grant & Carl, I can't comment on the Orion II but I do have an Orion with the built in tuner. I observe the same thing that Duane did, but with the tuner disabled (I don't use the tuner when driving
Grant, I ran the AM TX test "I think" you wanted. I was using a V1.37X version on the Orion. I varied the TX bandwidth from 3900 down to 900 while talking into the mike and transmitting, in AM, into
