RF gain issue
Comments

Do your S-meter still show S5? Are the s/w still show you are using the same antenna port as earlier? What does the SWR show when you transmit? I ask as this may help us to spot the problem.

The SWR was fine and no the S meter showed S1 when the RF gain was all the way done. Suddenly now the radio is almost normal except the RF gain has no effect on the S meter reading.

That is proper operation - the RF Gain should not affect the S-meter reading. There is a section in the SmartSDR manual on adjusting the RF Gain. I find that I occasionally need to adjust it depending on band conditions and time of day.

Just to add one thing, by altering the BW you will see different reading on the S-meter. Going from 3kHz down to 300 Hz will show almost a 2 s-unit drop (i.e. 10 dB). This is for noise only.

The S meter displays the signal strength (all signals the selected bandwidth) , unlike a traditional radio that measures the agc in the if stage to drive the S meter. On any radio if changing the rf gain affects the S meter, the s meter is inaccurate.

A few questions.
RFGain or AGC-T
What are the settings for both.
What bands?
What procedure are you using to adjust your AGC-T?

HI Mike, whatever the issue was with the Maestro it fixed itself!
I use the published procedure to adjust AGC-T.
The issue was happening on all bands. The issue was that the S meter fell to S1 and the sensitivity of the receiver was way down. Adjusting the RF gain made the S meter go up and down.
The radio suddenly popped back to normal sensitivity and the S meter back to it's usual S5.
Weird🤬

Hello, do you find any solution for this rf-gain issue? My new remote station with Flex 6600 is doing exactly same and all bands. Radio just have been only one week in my remote station and brand new. I was working remote, using internal antenna tuner and suddenly radio lost all signals. When i turn rf-gain to maximum preamp, signals came up. AGC-T is adjusted as usual. I tried to reset all tuner memories, factory reset whole radio and no luck. I have another Flex 6400 and it works just fine. Any ideas what might be the issue with 6600?0

This is not normal and not something we normally see. Please open a support ticket. If you can take a video of it failing, that will really help out the support team understand what is happening.
Don't forget to say what version of the software you are using.
