IF OUT question

Hello

Is there any CONFIG to activate IF OUT?

I connected a SDR-IQ to the IF OUT but nothing happens, maybe I need to
activate some functions?

Thanks,

Jorge

Re: IF OUT question

You mean with the KX3? If so, yes there is a menu
item for that.

Jorge,

If you are talking about the K3 IF output, there is nothing to activate.
Connect a known working receiver tuned to the K3 IF frequency of 8.215
MHz and you should be able to hear the same signals as the K3 is hearing
- you may have to tune a couple kHz in either direction to find it, but
the signal should be present.

If you have a signal generator connected to the K3 input, the signal may
be easier to find because it should be the only signal present.

If you have an older K3 (prior to September 2009), you will likely want
to add the IF Output Buffer Gain Modification which increases the signal
level at the IF output by more than 10 dB. See

The KX3 output is RX I/Q which is *not* an IF output (unless one
considers baseband as a valid IF).
It can connect directly to a soundcard, not a receiver (SDR-IQ is a
receiver).
Yes, it must be turned on in the menu.

Re: IF OUT question

Yes, his reference to IQ as in SDR-IQ made me
wonder which rig he had in mind, since he didn't
say and I've never dealt with an SDR-IQ.
