RX muting while TX - QO-100

#1

Unread post by py2oc »

Hello.

I've got an issue when transmitting while External Radio is active.
It seems the SDR Console detects external radio tx through CAT then mute and disable waterfall but the Auto Mute is disabled.
The issue happens only if External Radio function is active.
I tried it with two different radios (FT-897 and TS2000) and the behavior is the same.
Am I missing something?

I found out what was causing the issue.
The "Reduce IQ Data" option was enable with -30dB set. Solved disabling it.

Hi !
I have ft2000+airspay hf+ discovery running on sdr console.
CAT control is working well but when I push PTT on the transceiver the sdr not mute, and have a audio loop in headset with delay .
How can I mute the SDR ?

tnx

Try this:

Ribbon Bar, Home, Wideband DSP, Auto-Mute. This will be pretty instantaneous.

Hi Simon !
tnx for replay !
I try it but is not working . Signal from my TX is lower than the RX signals , so I can not adjust with this option.
Also in external radio >>transmit option I have enable Mute audio but nil .

There must be a mute option for the external radio, I will check.
