i have bad reception or bad semnal i need ATT,SM,SVC,DeE,AVC,SSM,COF

Hi, In my experience, the default settings seem to work well. I did change ATT from “AUT” to “1”, which removes the slight background noise in SSB modes. This is covered in the manual and does not really need to be changed.

Att

All the configuration options are available for the user to adjust if required. There will not necessarily be a single optimum setting for all conditions. 73, Dave

yes i know the default settings are good but with ATT i have problems but the SM,SSM,AVC is better to set the default or change it? in setting SM stay 0 SSM stay SNR AVC stay 60

Hi, I would expect that the default settings used in the Goshante firmware match those recommended by the PU2CLR SI473x library.

There is no IF output from the ATS-20. The demodulation is done digitally in the SI473x receiver chip.

As previously stated, the optimum settings will probably vary depending on band, mode, antenna, user preference etc.

ATT Increasing the attenuation level might be useful under strong signals conditions, but there is no front-end filtering so overload from out of band signals will always be a problem.

SM Soft Mute SSM SSB Soft Mute The soft mute only really affects the tuning experience. This was mainly noticeable in SSB. With the Goshante firmware it is much less of a problem because of the tuning method used. ATS20_EX

AVC Automatic Volume Control SVC Enable AVC for SSB The AVC might be useful for weak signals, but it will also increase the level of the noise. 73, Dave

ok thanks but avc should i set on 60 or set on 46(default)

G8PTN commented 3 weeks ago

Hi, If AVC set to 60 works better for you, then leave it at that. 73, Dave
