I don't know if it was mentioned yet, but on my Yaesu FT-891 I typically
have my DNR set to 4 and it seem to do a pretty good job of clearing up
the audio.
Also at a past Field Day event (all of them were in the past) at the
GOTA station we were being hammered pretty good by the other stations at
the KK5W site, so we found that using the attenuation function helped
tremendously. It might help with the noise issue as well.

Afternoon,
First of all, thank you for all the responses to my last email about
antennas. I have another question related to the same topic and looking off
some guidance. I normally setup my hf antenna for weekend use in my backyard.
It’s a mfj 1979 17ft vertical. It is mounted on a flag pole rod that I just
hammer into the soil close to the backyard fence. I have two sets of 4 radials
in 180 degree pattern since I have a fence on the other side. When I use the
rig expert to check swr, it’s always around 1.15-1.2. While the we is very low,
the noise is crazy high. Most of the stations are extremely noisy. For some
reason, I was able to hear really well few weeks ago. Is this something I am
doing wrong or something to do with propagation ?
For the above setup, I am always on 20m ssb. I do have few metal trellis
hanging near to the antenna few ft away but I am not sure if they cause any
interference.
Disclaimer: I don’t know how to read the noise level on my radio yet, apologies
if this is the most basic thing I should have known before I do anything.
Trying to learn as quickly as I can 😄
Thanks,
Venkata Appala
