You are a good teacher! Thank a lot and "73" to you!

Hi from Mason TX. Recently licensed and I looked hard at the 991A. I ended up with a FT-710 which is serving me well. I check into the Texas 7285 net pretty regular and I'm learning digital modes. 73 KJ5GQM

I'm a big fan of NetLogger. We use it for the North Texas NVIS Net on 40m and the Friday Night 2m simplex net on 146.580. Thanks for sharing, Steve!

I have one up 40 ft and it doesn’t work it is death my a 99 works better

Thank you for taking the time to do these tests for everyone!

so, is running an amp out of the question? it appears also that the sdrplay uses the port for an amp.

The antenna I'm talking on in the Video is my Hustler 6-BTV with about 32 ground radials its a great antenna and priced is right 80 meters is handled with the 80 meter resonator but it is narrow banded but I have my resonator tuned right to 3916 hopefully band with get better once we got passed this solar flare activity and storms de W5SLG

Interesting video and nice to see good operators! Thinking about getting that same radio.

Wow sounds good 👍👍👍

Excellent job Steve. It's great to see newer ops picking up a key and learning cw. Keep it up! 73 N9MB (ex KI5P)👍

at approx the 3:22 time signature you went off screen to find a signal, where did you go?

I have the Twin one Falcon 250, but antenna is complete depth.

Question for you; I have Win4Yaesu and my laptop is connected via a USB cable to the 991A. Love it works great. I did purchase a Toroid recommended by the author of the Win4Yaesu program. On my computer COM 7 is the enhanced port, and Com 6 is the non enhanced port, I am also running Log4OM and it uses a Omnirig port Com 20. FLRig wants to use my enhanced port, which I think prevents Win4Yaesu from using it at the same time, but I am not positive of that. What has your experience been with running DigiRIG, FLDIGI and Win4Yaesu?

Really funny, I am setting up one of these next week, 🤣 I have a 30 foot tower, and I had it up 2 years ago but the wind broke it in half, I took it to a metal shop and had the tube repaired, when I reassemble it I'll have to tune it, it should be fine, if I can get it close, it will be OK because I have a roller tee tuner so I can always dial it in, AI7VS 73s good video. 👍

Crank that power up Steve

I have my Comet250B set up on a temporary tripod .. hope to get my tower up before the snow falls.

Thank you for this video it really helped me set up my HRD software I've had for years just not on my FT991A.

You have to turn on the DM780 to get the waterfall ...

I wonder if the SWR is the same on the LMR setup and the RG setup. The .1 difference in reading is probably because the 8U has more loss. That loss appears as a lower SWR. So, your radiated power off the antenna for the 8U is perhaps lower than you think? Not by much... Not enough to matter. But interesting to consider.

My radio works on 40 m but don’t hear anything on 10 m ????

Looks like we have a lot in common. I have had the CHA-250HD installed for over 2 months and am using the FT-991A, too. The antenna is mounted to a steel pole only 6' above ground. I've been very pleased with the antenna's performance, as well. Much better than I expected. 6m -1.3 SWR / 17.7 dB loss 10m -1.07 SWR / 30.0 dB loss 12m -1.01 SWR / 43.0 dB loss 15m -1.05 SWR / 32.0 dB loss 17m -1.13 SWR / 24.0 dB loss 20m - 1.37 SWR / 16.1 dB loss 40m - 1.64 SWR / 12.0 dB loss 80m - 1.8 SWR / 10.9 dB loss KE8VEG, 73s

Hello, LU2AW from Buenos Aires, Argentina here. I have a CP610, and after watching all your videos, I can confirm the same issues with mine. I installed the 610 about a year ago, and at first, everything went smoothly. SWR showed as expected, well in line with the curves in the "manual." The best resonance was around 28.4 and 50.5 MHz. After a strong storm (I live in a building, the antenna is 60 meters above street level and very exposed), it bent at the base point to one side (not much, about 10/15 degrees), and SWR intermittently changed from 1.5 or so to 3.5:1. So I disassembled the antenna, straightened the lower pipe, reassembled, and erected it again. Now the resonance points are the same as with your antenna; the curve is the same. The best SWR on 6 meters is below the ham band, and on 10 meters, it's not as low as before. I'm thinking of bringing the antenna down again and opening the radial coil and the phasing coil to see what the hell is wrong. Maybe there is also some sort of impedance matching network in the feed point pipe. If possible, let me know your email so I can update you on my progress and discuss possible solutions. Mine is [email protected]. I think this is a great antenna as long as it worked.

Very Good video. I often wonder at times if my antenna isn't good, or whether I have too much local noise. Apparently it's working normally! So it was nice to see someone demonstrate the same radio with a similar experience. You made no mention of the RF gain knob, which I use a LOT. DNR does normally work VERY well for distant but stable reception, as you demonstrated, but I was listening to someone in Maine talk with someone in Florida. (I'm in Va.) They guy in Maine had 25w with a low antenna. Amazing... The ionosphere was distorting the signal and with DNR turned on, portions of the conversation kept faded out. I turned the DNR off and turned down the RF gain knob to halfway, while turning up the AF gain (volume). It wasn't as quiet as with DNR turned on, but I found that as you reduce the RF gain and increase the volume, you get their voices much better with LESS noise, and they don't distort when the ionosphere changes. So I actually use both options to clear up noise. I'm guessing of you already have a good antenna, the amp gain works against you by just boosting the noise? I'm using the DX commander Classic which is puling in a lot of conversations between 7 and 7.2Mhz in he evening from all over the country. Not to side track, but they say the more ground radials the better. Oddly I see very little difference whether I have just 1 ground radial or 30 connected. Maybe it makes a difference for transmission? Maybe my grounding system is acting like a radial? Since I just have a technician license I have no way to validate how well I can transmit. I decided to just run (4) #14 wire radials N,S, E and W. and I'm pulling in a lot of distant conversations in the evening. But thank you for the video. I've learned a heck of a LOT from ALL of your video's!

Brilliant video Steve, Most helpful 5*

Thanks for another trick to put in my toolbag! I'm just now starting to play with some of the settings. I've only played with the notch filter a little bit! 🤠

when you look at it. at least to my way of thinking,when you have a vertical quarter-wave with a single wire the same length it will end-up making a half-wave dipole be it straight down or at an angle like an inverted L

Not had good experiences with this antenna , I no the bands are a bit up and down a to the moment but at 20ft I couldn't hear anything but a Hash massive noise floor ,I did try a few things but for the cost it's not good ,my well brook loop was pulling things on 20mtrs that this antenna wasn't getting or was under the noise.prob works ok if u live on top of a hill or something.but not for my garden it's packed away I gave up on the thing for now.

I have a 991a, I also have a icom hf rig, the big difference between the two is on the 991 the rabbit hole is very deep, the sum menu, and secondary functions on all the buttons is very difficult to learn, you have to keep your owner manual at the ready all the time, but like all things we are still learning, thanks for the informative video 😊

I’m visiting family in Odessa and heard you on 40m CW calling CQ earlier. Wanted to QSO, but the fam had other plans, lol. Maybe another time, but you had a great signal with a solid copy. 73!

Thank you so much for your videos. They are very informative. I’m a new ham and have the 991a. It had been fun to learn. I’m learning how to do wiresX and c4fm which is kind of confusing. Keep up the good work! 73 K4PWI

Glad you're enjoying it Steve! Excellent video.. as always... guess you're going to have to get an amp to reach me on ssb. I'm sure you could reach me on digital and vice-versa.

Hi Steve, I have the same rig and antenna. What are you using for your feed line? Im using RG8X. Thanks for all your content. 73

Looks like a well made antenna that should perform well. The only challenge some might experience is installing it at such height.

I don't think the lock washers should go underneath the heads of the bolts. They should probably go under the wingnuts.

How did you scan all your memory channels

What antenna you using steve?

Thank you for a nice QSO on the 20m band. It was a nice opening to the USA and I'm happy to hear you too. Best of luck from Slovenia, 73's Janez S51DX

KI5JUF As a,newbee this makes me want to take out my FT991A from the box & start!! 73s 9V1KM KK7QGL SINGAPORE

I always enjoy your videos.

Πολυ καλη καιρεα !! Την Εχω και Εγω ΣΥΡΟΣ Ελλαδα !!! 73 !!

Nice job Steve. Gonna have to come see that antenna! de WZ5AB, Chris

I've got that exact radio at times I wish I knew CW

Thanks again for the great 991a/ham content!

I talk to New Zealand from Florida with one of these on 10 meters. It’s my first antenna. Why is this a dummy load? Please explain why this antenna isn’t good. I’m still learning

great and usefull data. Nicely done. I picked one of these up 2nd hard - looking forward to setting this us!!!

Thanks for putting this together. Any concerns with the Anit-sieze lub impacting connectivity between sections? I'd also be interested in yoru experiences using this antenna. Thanks!

Dummy load on a stick with cooling fins added nice touch. Actually a traveling wave antenna but a poor example since the radiation element is fairly small unlike its distant cousin the mighty 1200 foot rombic who also use a termination resistor although the good ones had a tune network. Also in the family are receiving beverages coming in at 800 feet and vee beems and of course the terminated folded dipole another dummy load.

Nice vid. Is it supposed to be veridical or vertical in this and the last vid? I had no idea that was even a word till I googled it 🙂

Nice! I had owned CH-250BX more than 10 years ago. It's very simple and easy to build. I enjoyed your video for cw qso with CH250. best 73 de hl1sb

Can this be used on GMRS? What is the SWR readings at 462.000 - 468.000?
