Any chance of moving the tuner to the feedpoint? With the tuner in the shack, it's making the match on the across the coax from where the mismatch actually is - at the antenna feedpoint - and you'll still be facing some coax loss. With the tuner at the feedpoint of the antenna, you should experience almost no coax loss. This may not be your issue, but might be worth giving a shot one evening when the weather permits...

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?

If you are using a tuner, then ground it. If the tuner is already grounded, then check your ground connections.

"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 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 yardā¦ Iām 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, LAā¦ KB7QLā¦.. often reports that I have a strong signal up thereā¦ 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.

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 itās a solar minimum but Iāve 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 thatās 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. Itās very discouraging. I can hear them - just can work them. :( - Chad ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org -- Jonathan Guthrie ARS KA8KPN ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org -- Clint Davidson KF5HDF 713-870-0195 kf5...@gmail.com<mailto:kf5...@gmail.com> ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org
