Re: Earlier Version of Fldigi
开云体育Hi Ken,Great to see there is progress! I am not familiar with the ASUS laptops. My fldigi setup uses the Upper Signal Level setting at -5dB and the Signal range at 80dB. Where you show -47dB and 51dB respectively. I am pretty sure you need a wider Signal range (that is dynamic range I think). The -47 dB setting on mine totally fills my screen with dark orange-red hash. What is your Windows Input Volume level setting for 2-USB Audio CODEC? Mine is set to 50%. Interested to know about that. If it is all the way up to maximum, something else is going on in the signal path. A SWAG: Some RealTek and Microsoft sound device implementations have a system wide output attenuator (IIRC a mixer setting, the headphone ear protection setting, or something like that) if you find that sort of thing, make sure it is not turned on. Have you tried transmitting yet? What is your Windows Output Volume level setting for 2-USB Audio CODEC? Mine is set to 100%. In the later case, I control the sound level by dialing back the fldigi Tx Level Attenuator to -24dB with my 7300 is set for 100% power. That combination yields about 35 - 40W out with a minimal (nil) ALC reading. When I drive my amplifier, I dial back even farther to about -28db - that gives me a clean 350 - 400W out. Hope we can help get you to the next step. Jack Spitznagel
