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

$1200.00 OUCH

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?

I thought these had a reputation as a terrible antenna

I have one....Works decent on HF. On 6M, its pretty poor.....

Not a bad Multi Band Antenna for it is if going vertical is the only Way for you to get on the Air from home or a tiny Vacation Place

Just bought one. I use the 25' Cha Porta mast and go portable with it. Everything fits broken down in the back of my pickup. I fit it to the top of the mast on the ground and lift it into the porta mast hitch mount, get in the back of the pickup, and elevate it.

Bottom part is a balun

Love the design

I like it good info on that antenna

Steve Thankyou X 10^10. This is priceless instruction. I am a NeewwBee following your instruction, it gives me Confidence to operate my FT-991A. THANKYOU❤ Cheers 73s🎉 9V1KM KK7QGL SINGAPORE

You are awesome!!!! Thank you for posting these videos!!!!!!!!!

THIS IS BRILLIANT!!!!!! Thank you!!!!

Isn’t there software to program all this stuff instead of doing it at the radio?

Great demo on the display and the waterfall for the 991A. 73s N4SLC

Your wrong I'n your test..wen you have the eq on and you turn the prosser on the prosser turns the eq off..the radio won't run the eq and prosser together

Steve THANKYOU🙏 For a frrshee newbee this is EPIC COOL, THANKYOU Steve❤🎉 73s 9V1KM KK7QGL Singapore

Thankyou for the Gr8 teaching for Newbees like myself to Appreciate my newly purchased 991A🎉. 73s 9V1KM KK7QGL Singapore

Thanks ka6bjs.

Is it OK to use the tuner on USB 10 meters?

Extremely helpful info. Thank you, sir.

My 991a tuner did the same thing today, it also flashed high swr while tuning. Did you figure out why yours did it? I xhecked my swr with my analyzer and it was good

I see you did a lot of research. Good job. I do have a couple things you may want to think about that are not widely known. One is that with a quarter wave vertical as you explain you need the other half of the antenna. With above ground radial they do need to be a quarter wave long, but there is no need for the radials to be a quarter wave long or the same length as the vertical portion. Think of an off center fed dipole. Moving the feed point off center simply increases the feed point impedance. As long as the overall antenna is resonant the vertical plus the radial length needs to add up to 1/2 wave. I will go one step further and say it does not have to be resonant as long as you match the impedances. It is easier if the system is resonant. With radials on the ground you are making a capacitive coupling with the ground. You need a low impedance connection to ground and that connection can be low resistance ( several ground rods) or low reactance (Xc). You want low impedance (Z). Z = R +jX so small R or small X either one will give low Z. The return currents will flow through R ( low R is less loss) or they will flow through X. In this case Xc. Large Capacitance means low Xc. However studying for the Extra Class you should run across the complete formula is Xc = 1/ (2 pi F C) so the reactance depends not only on C but the frequency as well. One thing to always remember in electrical circuits, whether it be AC, DC, or RF) is “ current always returns to the source”. With RF the source point is usually the SO 239 connector on the radio. So any current leaving the center pin must find a complete circuit back to the “ground side “ of the SO 239. That path is usually up the center conductor of the coax to one side of the dipole or the vertical element. The through the air and back to the other side of the dipole where it flows down the inside of the coax shield to the “ground side” of the SO 239. Here ground means chassis ground not earth ground. With the vertical and radials, the return current leaves the vertical and returns through earth to the radials where it flows through the capacitor formed by the radials and the earth, then to the coax shield and back to the source ( the ground side of the SO 239 on the radio. With no radials the return currents will try and find some way to get back to the source. It will not follow the path of least resistance. It will follow any and all paths that might exist. The largest current will follow the path of least resistance but there be some current that follows other paths also. Like current division in resistors when you have several resistors of different values, the current divides up in proportion to the resistance. Maybe I should say in inverse proportion to the resistance! I always recommend the ARRL antenna book ( you can’t have one too old either) and the ON4UN Low Band DXing book. It has a great section on antennas that applies to all bands not just 160 meters! There is a lot of miss information on You Tube so having multiple sources of reputable information to check against is extremely important. I am a retired EE and also have several old text books in addition to what I mentioned above. It’s a complicated subject with a lot of myths people believe as the truth. You did a good job keep up the good work! Forgot to mention that a 1:1 SWR is not necessary. Total loss in dB is what is important. Sometimes a high SWR only adds negligible loss and sometimes it does not. It all depends on the matched loss of the feedline to start with.

That is you receive bandwidth, you set your SSB transmit bandwidth in menu #110!

Thank you so much! Started using WSJT-X with flrig, makes life so much easier. NOTE: Playing around with the commands in flrig with the FT-991A, did you know that you can string multiple commands together in one button? Here is an example that doesn't do anything super useful but works :-) LK1;NR01;RL001;PA01; Locks to Freq knob, turns DNR on, sets the DNR Level to 1, and sets Amp1 on. Thanks again!

Learning something new about the ft991a every day, thanks.🖕

Danke.

What happens if you change frequency without undoing the tuner button?

None of Yaesu's radios provide a waterfall without external hardware. Win4Yaesu supports the SDRPlay devices directly or any other SDR though its native software and the third party interface of Win4Yaesu.

the other guy needs a hearing aid

Tks for your video, and in FM, is possible ?

I’m loving your ft-991a series … you are prepared for each

I just bought the same antenna. I appreciate the tutorial.

Cool! I had no idea.

Are you suggesting that unless I use 1/2 or odd multiples of 1/4 wave coax lengths my system is not efficient? How does my Tarheel or my DX Commander work with the same length of coax and near perfect matches? SWR reflections are still radiated. I am not disputing the effect you have demonstrated but it makes no difference if you use a tuned antenna.

Excellent info. Thank you!
