Drive level issues
Posted: Fri May 01, 2020 8:52 pm
Hi,
I've managed to make my 7000DLE Mk2 with Firmware 2.0b work with SDR Console 3.0.22, and I've run into a very interesting issue. The TX Drive setting in SDR Console seems to be way off. In my first tests with a drive setting of 50 (using JDTX to generate an FT8 signal at 0dB), I saw the needle of my external Watt meter jump to the maximum of its 300W range! Needless to say, I was very quick to reach for the power switch. Trying again with very low input levels from JTDX, I ended up having to dial the drive down to 2 (out of a possible range of up to 100!) to get the 50W output I actually want to run on.
So, multiple questions here. Did anyone else notice this problem before? Is it actually possible for the radio to emit more than the 100W as per specification? Can I damage the radio with the wrong drive level values?
