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
Sweep ADC produces 32768 samples at 8 MS/s in 4.096 ms. Following those 4 ms, Sweep ADC is completely inactive for ~2 seconds. Don't know why, but it's clear that any fast changes are not related to
Orion (and Icom units, probably) doesn't do any scanning at all. A wideband IF signal is sampled at 8 MS/s, and its spectrum is computed. The problem comes from the fact that samples cover only 0.2
Just curios, what is the bandwidth at -6 and -60 dB? 73, Sinisa YT1NT, VE3EA _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mail
It's not Orion, but will do well, particularly if you use attenuator and IPO to prevent S meter from reading above S9+10 dB on nearby frequencies. 73, Sinisa YT1NT, VE3EA ___________________________
Any speed will do. Listen on another RX, not sidetone. 73, Sinisa YT1NT, VE3EA _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/ma

Assuming that you didn't get a defective unit, try increasing AGC Threshold in RX menu. Forget about NR at least until you get a decent copy withou it. More details in: http://www.geocities.com/va3tt
Yes and no, depends on noise. For the "background" type of noise use hand time > 0 and slow decay. For strong impulse noise and strong atmospheric crashes using zero hang time and fast decay in order
A pair of steady carriers is equivalent to a DSB signal, i.e. resulting amplitude is not constant at all. Fast AGC tries to reduce the apparent depth of modulation, resulting in distortion. 73, Sinis
Are you seriously suggesting that TenTec performs FCC certification with each release? 73, Sinisa YT1NT, VE3EA _______________________________________________ TenTec mailing list TenTec@contesting.co
Unfortunately, the same codec is used for front panel headphone output and rear panel aux outputs... 73, Sinisa YT1NT, VE3EA _______________________________________________ TenTec mailing list TenTec
All the mess is created by attempting to feed 6 destinations (speaker, headphones, 3 aux outputs) from just 3 sources (3 DACs). Therefore, aux outputs cannot be independent from speaker/headphone out
AUX RX (if selected) stays connected to RX input during transmissions. Board A3 (RF Converter) has a pair of antiparallel diodes that will protect main RX, at least until they get destroyed. It would
On AM mode the sub RX cannot tune in steps smaller than 2.5 kHz, regardless of what the display tells. 73, Sinisa YT1NT, VE3EA _______________________________________________ TenTec mailing list TenT

My Orion puts out 20 W in TUNE mode, but the meter shows over 40 W. I've determined that the meter itself is highly nonlinear. 73, Sinisa YT1NT, VE3EA _______________________________________________
And how would you call a lot of Orion work that is in progress at TenTec right now? 73, Sinisa YT1NT, VE3EA _______________________________________________ TenTec mailing list TenTec@contesting.com h
