- Most modern radios have SWR meters built in. The Icom 7300 has several ways to use it, including a function that plots SWR vs frequency. Let's jump in!

Another great video, very pleased you are making a speedy recovery... J
Well Dave, I already knew about that very 'nifty' IC-7300 SWR meter graph ... but I didn't know about the screen capture function with the power button! Very nice ... I always learn something new from u :) 73 KJ6ER, Silicon Valley
FYI. The manual says you need to select the RTTY or RTTY-R mode and run your power at 30% when charting your SWR.
That's true
buy who's running at 30%..?.... that's only a starting point so you can see for the first time your actual swr...if it's safe, then you can do at 100%, power...it will change the swr alittle higher but only alittle
Yet another awesome video Dave. I love your channel!
GREAT, great video Dave! And many thanks to that other Oggie for recommending this topic & instruction! On my 7300, I really haven’t used anything more that the smaller SWR meter in the upper left, and used my external tuner. But I’m definitely changing mine to the ‘bar’ meter now as you’ve shown, I believe it paints a MUCH more thorough picture of the transmission! Side note, you’re looking much better Dave! You have more color back in you, and your voice is sounding strong again. 73!! (N4BDW)
Wow, the more I see of the 7300 the more I like it. I'm buying one!!
Thanks for the video Dave. You look and sound much better.
Another great one Dave. Thanks for sharing.
Sweet! ThankYou David!
Good Video. I am a old school Tube Rig Guy with Johnson and Collins. But seeing this and your other videos with the IC7300 I may just get one. 73's W3AMT
Great video Dave.
I recently sold my 7300 and bought a new IC 7610 .. I miss the SWR Graph that the 7300 has dearly or even greatly. C'mon Icom, do a upgrade and bring the SWR Graph to the 7610! Thank you for this video and explanation Dave! 73.
Good Information for ALL....thank you sir!
Thank you, Dave. Interesting how many functions are packed into these radios. N0QFT
Thx, Dave. Again, well done!
Boy I sure want a 7300!! Great video Dave! Thanks for sharing. 73, KM4OCJ Todd in south central Kentucky
Dave, if I am not mistaken, and have seen it on my 7300, it remembers tunning in Freqs you have been to before until you reset it.
yep, funny who knows what isnt it?
@@forgetyourlife There is a lot to know.
Thanks Dave, I didn't know that about my 7300
THanks Dave. Can you post the settings you use for your scope and waterfall?
Great video. Thanks
Thanks Dave, another great video!
One clarification for the IC-7300... It remembers up to 100 internal antenna tuner settings as presets. Once you "tune" the radio, it remembers the tuner settings for that particular operating frequency as a preset. If the tuner is enabled, as long as you are within +/-1.5% of the frequency of a stored tuner preset, the tuner will use that preset otherwise the tuner will be disabled.
Cheers & 73!
Thanks for the info!
Thanks Dave!
I love my 7300, but by no means do I know all of the features. While I have done these measurements on mine in the past it was still cool to follow along and see how my little NVIS wire antenna is holding up. (no complaints) ;)

Thank you Dave. Great stuff to know. 73 de KG7LOI.
I did not know that was there. Cool.
The 7300 does have a auto tune function. Turn it on and it will retune when you key the mic if it needs it. Depends on how far off your SWR is.
Wow! What an information-intensive video. I commented in your video about why 50 ohm as it relates to my newly purchased Eton 750. I’ll be honest, I have been drooling over that ICOM 7300. Disclaimer: I do not have a ham radio license-yet. I’m just starting out, but trying to rationalize getting the 7300 and returning the 750 (free returns). At some point I’m confident I’ll be getting the 7300, so do I just get it now? Or keep the 750, knowing that at the point I get the 7300, what I paid for the 750 will just be added, essentially, to the purchase price of the 7300? Also, do I need to purchase a separate power amplifier for the 7300? Or can it plug into an AC power outlet? So many questions! Thanks again-your videos are amazing, and full of very interesting information. From reading some of the earlier comments, it appears you weren’t doing well recently. I’m glad you seem to be doing better-keep it up and hang in there!
I have the 7300 and this was very interesting. I also have a 590 ken-wood and a older Icom I want to get the ldg tuner for it. i guess it is the pro 100 I have been trying to figure which tuner is best for the 7300
The built-in tuner is all I use and it works well.
I'm getting ready to shorten my 5/8th CB vertical for 10 meter work, and when I tested it one last time in its current 11meter length for SWR I found that I'm getting different readings from different meters. The cheap CB transceiver meters are notoriously unreliable, but I was a bit surprised when my MFJ Grandmaster SWR meter read differently than my Workman CB external SWR meter. Everything I heard was that external SWR meters should be pretty spot on, but I guess not this time.
The Workman has often "agreed" on SWR readings with the transceiver's internal SWR meter. But, I would suspect the high price, high end all HF/VHF SWR meter would be the one to place the bet on. Could you offer a bit of wisdom on the difference?
And thanks for working to make all these videos!
@H Higgins Both of my CB transceivers and both SWR meters were purchased new, in sealed packages.
I've been wondering, on the 7300 when it's doing the SWR plot, is it transmitting with some significant amount of power? Similarly, I sometimes see little blips go racing across the band, is that someone using something similar that is measuring SWR?
In fact, at 7:23 in this video you can see one of those "racing blips" I'm describing.
Usually those blips going up the screen are ionosondes, which are a form of radar used for ionospheric sounding.
Dave I am just starting to study, can you explain more about what SWR is ? What does it mean in practical terms. My book comes in 2 days .... then I can study it more . So far I am lost in lingo ....
Hi Dan, good luck in your studies! SWR is an abbreviation for Standing Wave Ratio, which isn't very helpful, is it. See this video: ruclips.net/video/BpIQH6PgpeA/видео.html
Does swr mean short wave radio?
Standing wave ratio. It tells you how much of the power is being transmitted or lost in your line and antenna vs reflected back to the radio. A properly tuned antenna will have a low swr, as will a dummy load. However the antenna will transmit the power and the dummy will absorb it all, not transmitting any usable signal.
The Xiegu G 90 has does not need to press button and better graph in my opinion
Nice............
Most people might call me a dummy, but what kind of S D card does this rig use? is it a card like you use in your camera . yes I'm old school.
Yes, it's a card just like you might get for your camera, but no bigger than 32 GB.
I found this on the rig but have never needed to use it
Tip: Tuch and hold the S meter on the main screen..
Dave, take your vitamin D or get more Colorado sun ~ k6sdw
the $3000 dollar 7610 does NOT have this..Thanks Icom.
But please don't tune on the frequency where someone is talking. It's just rude and hurts the ears.
