Re: Use Of AIRSPY HF+ With K3 (S upgraded)

Unless I am doing something wrong, I have found that the RX Ant output is only enabled when the RX ANT switch is pressed. Of course, this means that the K3's receiver gets its input from the RX ANT input. So, what I do is connect a cable to RX Ant Out with the other end connected to a splitter (actually, I just use a BNC tee) - one leg of the splitter's output goes to the RX Ant In jack, and the other goes to the SDR. I can use the SDR and/or the K3's receiver simultaneously. Note that there seems to be a low-pass filter in the path to the RX Ant output, which means that if you put the SDR on a higher frequency band than the K3's main RX, its input will be attenuated. I believe this is the same phenomenon that occurs with the K3's subRX when CONFIG:VFO IND is set.
