Re: [BVARC] Signal noise and suggestion on how to reduce it

[Venkata Appala via BVARC]

Thanks John. I set the DNR to 4 already. As Jeff(Greer) mentioned, it appears 
the main culprit could be the way I was running my coax in the home. I was 
running it near to the kitchen appliances and guess that interfered. I set up 
the radio this evening and it’s performing way better than last two weeks. I 
have to yet turn on the DNR today :). Rick sent a nice article on HF receiver 
basics and I am planning to go through it which might help understand the 
various components including attenuation.

Thanks once again for the guidance,

Re: [BVARC] Signal noise and suggestion on how to reduce it

[John Denison via BVARC]

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.

Re: [BVARC] Signal noise and suggestion on how to reduce it

[Rick Hiller via BVARC]

Venkat and Chris,

Have a read of this Radio Hotel column...from September 2017

https://bvarc.org/rh/rh_1709.pdf  HF Receiver Basics

It might shed some light on your issues.  Might not solve the noise problem
completely, but it will steer you in the direction of having your HF
receiver set up properly.  At the end of this Radio Hotel article is a
reference to an ARRL "The Doctor is In" podcast with Joel Hallas (sk) that
will add some additional enlightenment.   Do a search on QST for HF
Receiving.  Lastly, the ARRL Operators Manual will shed some light too
along with a visit from your well experienced Elmer.   .

Looks like you are on the path to understanding HF receiving.  I wish you
well.  Enjoy the hobby73...Rick  W5RH

Thank you Rick. I realize my knowledge on using the radio is very minimal and that can also be a factor. Ordered the radio today guide to ft 710. Amazon delivered it recently and Will go through it. It seems to have lot on it formation on how to use each knob/ setting on the radio. Thank you for the rf gain tip.

Re: [BVARC] Signal noise and suggestion on how to reduce it

[Chris Medlin via BVARC]

Cool thanks for this info Rick. Up until just a few years ago I have always 
been a die-hard Kenwood guy for HF (TS-120 then TS-570S), now the very popular 
991a, I never would have known this info. And believe it or not, I’ve read 
through the operators manual more than once.

Next time I fire it up, I will definitely have to tweak my RF Gain and see what 
happens.

On Yaesu radios ensure you pay attention to IPO -- Intercept Point Optimization 
setting.   Also ensure your RF Gain is not  on "13"  (reference to Spinal Tap) 
but more at the point where the S meter is riding the band noise peaks.  Also 
ensure you NB is off or if you need NB for some reason, adjust it to just 
handling the impulse noise and no further.
Sorry it this is a repeat of info, but I have instructed quite a few Yaesu 
users to adjust their radios as they had all controls set to "13".  it quieted 
their receivers down quite a bit.

That’s awesome John. Loving the radio. The antenna setup is super fast as well. 
I am done in 5 mins. Just purchased the wolf river coil and hopefully, will 
join the bvarc rag chew soon.

Re: [BVARC] Signal noise and suggestion on how to reduce it

[Venkata Appala via BVARC]

Jeff, you might have solved my problem. Couple weeks ago, I started routing my 
cable via kitchen to avoid kids( one of them is just 3 yr old) and close to the 
appliances. That might be it. I will go back to my old way of routing cables. 
Thank you for the suggestion.

 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 

Re: [BVARC] Signal noise and suggestion on how to reduce it

[Jeff Greer via BVARC]

I have found that I can get noise sometimes when the dishwasher or washer/dryer 
is running. Keep the coax as far away from house walls (wiring) as you can. May 
help. Also, learn to narrow your filters. I think you can do that on the Yaesu. 
But if you can, test the radio with various things in the house turned off and 
on. You may well find a culprit.

Hello everyone,
 Thank you for the quick replies. Sorry, was driving home and couldn’t reply 
earlier.

About the radials, they are 14ft each copper wires. Thanks for the suggestion 
about extending them. Will try to build more in the coming weekend’s.

On the radio, it’s a Yaesu ft710. I am using the dnr but last weekend was 
worse. I just went back and took down the antenna to figure out what’s going on.
On the power, I need to look into it this weekend. I am using a surge protector 
connected to powerwerx supply. Will try to connect directly and see if that’s 
the culprit.
About the inverted antenna, I need to explore this option. Should be a good

[Jeff Greer via BVARC]

How long are the radials?  The more copper you can put on the ground, the 
better. If they are about 15' long, doubling what you have should do a good job 
for you.

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.

I am using the same type of antenna. The MFJ 1979. I have mine mounted on my 
metal fence in the backyard. I do have noise but since I got a new radio, the 
filter knocks it out and I am able to get good copies on everything. Check 
things like your power supply and cut the power off in the house and see if the 
noise drops at all.

Re: [BVARC] Signal noise and suggestion on how to reduce it

[Nick Creason KE5QY via BVARC]

Hi Venkata,

Vertical antennas are noisy because most man-made noise is vertically 
polarized.   An inverted V on 20 meters with the apex at the top of a 6-foot 
fence and the ends about a foot above the ground will be quitter and may even 
give you better coverage.  You can make a fence tip antenna out of a few 
dollars' worth of wire and have some fun.

I have good luck nation wide with my fence mounted antenna and a hundred wats.  
And best of all , my HOA has no idea I'm a ham.

Look up NVIS antennas on the internet.  There is a lot of info on these low 
wire antennas.

Nick, KE5AY

[BVARC] Signal noise and suggestion on how to reduce it

[Venkata Appala via BVARC]

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.
