Great video! You addressed one of my my pet peeves involving recent radios: too much effen' gain! Thanks for showing how to make this rig have a quiet receiver.
Cheeeeesh! We've been reducing RF Gain on receivers since the 1930's. This is like rediscovering the wheel. You simply reduce the gain to below the noise level. The problem is that each band has a different noise threshold which becomes a lot of trouble when band hopping. This same setting on 10 meters will make the receiver deaf. Thus this is why we have AGC or automatic gain control. With AGC we can leave the RF gain at maximum and strong signals won't overload us however the tradeoff is having to listen to receiver background noise. Pick your poison.
Mine has a constant S3 white noise background level even with antenna disconnected, on all bands, running on a battery and tested taking it miles away to remote location. End up having to run it with rf gain reduced to 70% and consciously adding 1 or 2 S points to any signal report. Pity DSP units are so expensive; about half the cost of the G90.
Mine too, S3 noise. As much as I love the G90, and fiddling with the gain and filters helps, I ended up buying a 891 and am selling the G90. I don't use the tuner in it.
New G90 owner here. I haven't got the chance to play with mine with but will this also work in SSB mode? I often hear others saying the G90 can become tiresome to listen to for long durations.
What firmware do you have? Are these adjustments available with v 1.6? I am reluctant to upgrade firmware yet, due to the hassles and bugs I've seen posted, as my rig runs fine for what I need on 1.6.
Yes that statement is true but all radio's i have used if you turn rf gain to anti clockwise stop you hear nothing so tell me Rick why do you still hear a signal loud and clear on the G90 with rf gain at 1%

This video helped me. Ignore the haters.
Hi Petr, this are common sense tweaks good for any radio not only for G90.
Definitely agree. I noted it cos this overgained radio sounds noisy in basic setting but it can be tweaked so nicely...
Thanks for sharing this information
Thanks for the video.
Is there a way to reset default filter settings once you shifted or adjusted it?
Compare reception of the same station at the beginning of vid and in the end... ;)

Every radio tuned to HF/VHF/UHF will become tiresome to listen to for long durations. They produce 'white noise'. Best Regards and 73.
No squelch. 😔
Where is the squelch ?!?

Used 1.74 build 003. I am not sure with 1.6 but it should work too.
Thanks.
220 volt?
Well hell. I can make it quiet by turning the damn thing off!
Lol...
You can turn down the rf gain on all radios. This is all about nothing.
So why most of US ops does not use it...?! See most of noisy G90 on YT...
There are a ton of questions all over the internet and social media groups asking about RF gain. Clearly a topic of interest for others...

This about RF/AF and filtering in the best combination to reduce noise.. its a dynamic adjustment.. video is correct and useful..thank you
