ADC overload when tuning amplifier.

[K4HNO]

Is there an option for auto-attenuate to function when using the TUN button? After using pure signal with a barefoot rig I forget to adjust the step attenuation value and overload my receiver when I start to tune my amplifier. This is a mistake that is very easy to do. I would be happy if I could force the attenuator to a certain value when using TUN, but I don't see a setting for this. Am I missing something?

There is no such function currently in the software, I'm afraid.

The good news is that as long as you are not exceeding +13dBm (20mW) at any RF input connector then your hardware is safe and this is merely an annoyance.

At 1500W (62dBm) you need to ensure a minimum path loss, coupler plus any attenuators, of at least 49dB prior to the radio.

Thanks Scott. I wasn't sure of the limit that the receiver hardware could withstand. I have a total of 53db of attenuation so I am ok.
