[Kenwood] TS-930 and IF OUT

Sat Oct 6 16:02:00 EDT 2007

I'm interested in using my TS-930 with a Softrock Lite software defined
receiver. In order to do this, I need to be able to tap the signal at the
8.830 MHz IF.
According to the TS-930 manual, it has 4 IFs: 44.93 MHz, 8.83 MHz, 455 KHz
and 100 kHz. It is not clear to me whether the IF OUT on the back of the
TS-930 taps the 8.830 MHz IF or the 100 kHz IF. The TS-930 manual includes a
description of the IF OUT jack: "A high-level, narrow-bandwidth 100kHz IF
output, taken before the receiver product detector, for scope display of the
received signal waveform (to feed an SM-220, vertical input)." I am not sure
whether the "100kHz" reference in the previous sentence refers to the IF
frequency or the IF bandwidth.
I've checked the manual for the SM-220 but it does not describe the IF OUT
for the TS-930. However, the manual for the TS-820 clearly states that its
IF OUT is 8.83 MHz. Since both the TS-930 and TS-820 work with the SM-220,
it seems quite possible that the TS-930 also has 8.83 MHz at its IF OUT.
I've just started learning about software defined receivers and am not the
best at deciphering complex schematics. Can someone help me determine which
IF is tapped by the TS-930's IF OUT?
Thanks.
