I dont have a ground on the ATU as I am in the middle of my house and would
have to run one the same length of the coax I have to get outside - 40 plus
feet up a wall and through my attic to my bonded ground outside where my
lightning arrestor is. But on a 12 volt DC system for my radio and with 9 AA
batteries running my ATU do I honestly need one? What would be the difference
if i was running outside off battery?

Here's something I learned from some more experienced operators a while back.
If you are using a tuner, then ground it. If the tuner is already grounded,
then check your ground connections. Best DX and 73

Several things. First, the antenna analyzer won't tell you very much. "The
proper tool to assess antenna performance isn't an SWR meter, it's a field
strength meter." On the other hand, if you have a high SWR on your antenna,
that might be causing your radio to dramatically reduce its power. 100 watts
is certainly enough to communicate all over the USA.
Many of the problems I've had with low 80 dipoles were due to the coax. You
might check the coax for shorts and opens. Back in the good old days, I used
to have splices in my coax and they'd open sometimes. I could check that by
unscrewing the shield and if it got louder with just the center conductor in
the SO-239, then I knew the feedline was bad.

I am also learning but way behind you. But I think you should first run
antenna analyzer to be sure no issues there. I bet somebody would lend you a
Rig Stick or VNA unit, I would 😁

Keep experiencing. I bet somebody in BVARC will come thru with help.
I have an off-center fed dipole about 135 ft. total length up about 12 ft. in
the back yard… I’m near N. Eldridge Pkw and Tanner. My signal into the BVARC
HF Wednesday net is minimal but I usually get checked in. About the same with
the Louisiana Traffic Net. My brother over in Ruston, LA… KB7QL….. often
reports that I have a strong signal up there… about 300 miles. He has a long
loop up about 15 ft. He often has a strong signal into Houston on 3910 kHz.
Keep trying and I bet things will begin to change for you.

I’ve been a Ham since 2017 and have an 857d. Running a multi fan dipole from
2017 until I had to cut the tree down it was in in 2019 I had dismal contacts
with anyone on 80, 40, and 20.
Covid gave me some time to be at home and I setup a Hustler 6BT and have it
tuned with my MFJ 269c. I know it’s a solar minimum but I’ve made very few
contact. I can hardly reach the Texas Traffic Net and I try each day. I might
get a check in 2 times a month. I have yet to be able to check into the 3.910
Wednesday net. I can hear everyone but no one can hear me.
I recently built an 40/80 meter coil dipole that is an inverted v that’s 18
feet at the center and 6 feet at the ends - nobody hears me with 100 watts -
even the 3.910 net.
Is 100 watts just too little these days? Should I be looking to buy an amp. It
seems people with higher power are the only only people who get heard. It’s
very discouraging. I can hear them - just can work them. :(
