It is the codec clock that matters here, and both codecs use a single crystal; so the problem is elsewhere. 73, Sinisa YT1NT, VE3EA -- YU DX Contest April 15/16, 2006 http://yudx.net 2 x 8 hours of w
On the contrary, the "I hate the Orion" crowd will sell their Orions at much reduced prices, so the rest of us will benefit by buying them out quickly. And if someone from the rest of us happens to f
Believe it or not, the "565 Manual" does not even attempt to define how is the the TX mode established! Therefore it cannot be a software bug, because there is no specification. It's only specified t
Was he able to explain how is the TX mode actually established? The manual does not even attempt to define that. No, it cannot be an operator error because the correct procedure hasn't been defined.
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) carrier at
By "S9" do you mean -73 dBm level or just "9" on the S meter? My test was done with a known level in dBm, preamp on, attenuator off. As my Orion was still open, I made a quick test by feeding 14 kHz
The following 100 Hz DSP CW filter response was measured with a calibrated signal fed directly to ADC input on A7 board. 156 Hz width at -6 dB 378 Hz width at -40 dB (sidelobe peak) 512 Hz width at -
Exactly. It is easy to verify that with V2 a strong carrier off-tuned to just become inadible is still causing S meter deflection and AGC action (with threshold set appropriately). 73, Sinisa YT1NT,
FAST rate is only 250 steps per rotation, and SLOW amount to mere 62.5 steps per rotation, making it feel too much "digital" if STEP is 100 Hz, and too slow with 625 Hz per rotation, if STEP is 10 Hz
I attempted to measure AM RX audio response with 2.056 a few times, and in all ocassions it was 3 kHz on both main and sub RX. RX filters were fully open and RX was fed from a signal generator having
With V1 firmware the indicated AM bandwidth was that of the recovered audio. With V2 it is the actual IF bandwidth, limited to 6 kHz and preventing any response above 3 kHz, unlike V1. 73, Sinisa YT
