World-class QSK! Hear between the dits at over 70 wpm. The top
trace above is the RF output at the antenna jack, with Sienna
sending two dits at 60 wpm. The bottom trace shows the Side-
tone, and between the dits, received audio. You can see that the
receiver recovery time is only 10ms. Also note the “clickless”
audio (no glitches in the waveform), and the smooth rise and fall
time of the RF envelope.
Think you can’t have high performance in a kit radio? Think again!
Sienna offers top-notch performance for the most demanding operators!
Sienna has up to 4 selectable IF filters at the 2nd IF, and 4 more at the
3rd IF. Each IF can be “slid” back and forth against the other to effec-
tively narrow the bandwidth. Above left, you can see the front panel
display with both filters centered and the resulting spectrum plot of a
signal in the passband. On the right, one filter has been slid over
200Hz, and you can see the resulting smaller bandwidth.
