My 7300 is shipping to me today. A fellow ham sent me a link to your videos. What a wonderful resource to have available to learn everything there is to know about this radio.
I’ve had my 7300 for a few years but due to job and family didn’t use it very much. Now that I’m retired I’ve been watching your videos and learning how to use this great radio. Thanks for all the work you put into this. Bob KV4PL
Thank you Tom, these videos are fantastic, especially for someone new to ham radio. I appreciate how you compare the performance of each function to other rigs you have used.
I love your videos and recently purchased a 7300. I have been using your videos as my manual because I have low vision now and changed out my HF radio to this for that reason. I really love this radio and the features. Perfect for me now and I am doing a video on why I like it with my vision, should be out in a few days but I am planning on mentioning your channel in my video. I like the features on this radio over my FTDX 3000 for my eyesight and am having fun again on HF! Keep up the good work.
You gave the best description of what the IP+ function does and what it is “intended” for that I could find on the webs. This is by far one of the best video series on the IC 7300 there is! Thank you! 73
Just got my IC-7300 and just now working my way through these VERY HELPFUL videos. One tip I've heard and it works for me: activating the NR function makes the audio sound a little muffled (at least to my old ears). One can mitigate that effect by boosting the audio treble a couple notches: Menu/Set/Tone Control-TBW/RX/SSB/RX Treble.
Hi Tom; I got my 7300 about 2 1/2 years ago and just stumbled upon this series a few days ago. After viewing only about a dozen or so of your videos I have greatly expanded my (limited) knowledge of the 7300, especially in operating the various filters available. I intend to view every one of them and really appreciate all the time and effort you;'ve expended to produce these. Thanks and 72, FA W1ZAH
Great Videos Tom - Often gaining more concise and easier information than reading the Manual. A real pleasure io watch your very professional videos on the 7300 73's VK4MO
Just got my 7300 last week. Don't really like reading manuals. Have "binge watched" your series to here and am going to continue. I'm really enjoying it. Hope you will consider doing further presentations on more equipment.
In rural areas the prime use of the Noise Blanker is to remove the pulse noise caused by electric stock fencing. At my location it fixes this completely and the energiser is in the same shed and the antenna is attached to fence posts!
Nice! I’ll have to remember that next time I want to demonstrate this. Especially if I do any live demos or trainings. My wife has horses and we used to have our own place with some pasture. A small battery/solar fence charger would be perfect to show the type of noise that the NB helps. And it would be a lot quieter than the leaf blower. 😉
Even with those NB and NR thing the 7300 has a very strong HISS noise. I almost sold my 7300 BUT after putting a WestMountainRadio CLRdsp am loving my radio.
I have heard that IP+ ADDS a dithering effect or concept to excite the lowest level signals it exaggerates the high spots compensating and differs the low spots creating contrast in the signal itself. I think I can source ham radio concepts for this. He didnt explain it quite the same but that is the idea i got
Thanks Tom... I got a better handle on IP+ now... The Icom description in the manual reminded me of Chinese instruction manuals... Circular in nature and sometimes referring to dragons..... hehehehehe K4NAL
If you ever do mobile operation with it or if you use it at a Field Day or similar event with generator power, you might yet find a need for it. Thanks for the comment. 73, Tom
@@HamRadioA2Z only on older cars. it was primarily against the old distributor noise. you know the one with the rotor spinning. nice video though. kudo's
The newer cars with coil packs right on each plug are definitely less noisy on HF. Although, funny enough, I use the noise blanker in my 2018 diesel truck. Obviously, there’s no ignition noise, but the electronically controlled fuel injectors put out a pretty good pulse noise when they are firing.
Unless, like you say for very weak stations, why would one NOT use NR? I mean, who WANTS the noise? I would think the default would be always "On". I always have mine on. Thx, another excellent vid.
IP+: based on what I knew, it is more about data point interpolation. IC-7300 has 14 bits RF ADC (Analog to Digital Converter). which theoricaly has 14 x 6 = 84 dB of dynamic range. The IP+ enhance the sampling data and 'guess' the signal strength up to 16 bits, and enhanced the dynamic range up to 16 x 6 = 96 dB. That's why in Sherwood test report, IC-7300 has 94 dB of dynamic range when using IP+. In short, it is a data manipulation to increase RF dynamic range, which may increase RX performance. Again, correct me if I am wrong. Thank you. Yours, Bahatir 9W2GNU, 73...
I looked at the Sherwood report. I also found a review by AB4OJ here: www.ab4oj.com/icom/ic7300/main.html. I don't believe they are exactly "interpolating" the additional 2 bits of resolution. The article from AB4OJ says that when IP+ is on it activates ADC dithering and a randomizer. If I understand correctly, I believe what they are "dithering" is the gain of the preamp coming into the ADC. I also suspect they're changing the gain by an amount that changes the value for the same voltage by less than 1 bit or at least by an amount that isn't an integral bit value. This would have the effect of producing readings in between the last sample and effectively give you more bits. Since you now have to process data across several samples, it would also effectively reduce you maximum bandwidth. Although the A/D can do 124 megasamples/sec, they have plenty of oversampling for every band except 6 meters. Unfortunately, unless Icom decides to make the firmware open source, we'll never know exactly what they're doing. Thanks for your comments. Good discussion. 73, Tom
Well, not so much double talk, but incoreect or at least different uses of "Verbs" by the interpreter. The next sentence gives even more clues. "Optomizes the A to D converter (another words, using the info gleaned from the digital A to D converter to work with the noise AND using it in a optimum manner) … " Which to me means the are analyzing the audio with the digital circuitry of the circuits and then applying that to the distortion and hopefully removing distortion. Cool. zz"
I got mine today and love it, but somehow talkback has got turned on, I can hear myself through the speaker and it squeals to holy hell, I can’t for the works of me figure out how to disable it
Hi. You need to turn the Monitor function off. Press the Function button in the bottom center of the front panel. On the menu that pops up on the screen, touch MONI on the lower right to toggle the monitor on and off. You can also push the multi-function knob on the upper right corner of the display and touch Monitor at the bottom of the window that pops up. Then you can adjust the level or touch repeatedly touch Monitor on the screen to toggle it on and off. Look on page 4-11 in the manual. Hope this helps.
You talked through the demonstration of the NR so we weren't really able to hear the difference. Next time, try to talk a little less so that we can hear what is being demonstrated. Good video overall.
I am new to ham radio. I find these videos very helpful as I learn to use HF and the 7300
Just got a 7300, and a general license and these videos are great!
Thanks! Glad you find them helpful.

Thanks! Enjoy the new rig.
I bought this radio as entry level into HF. Yourr tutorials are very helpful thank you.

2. Those darn Leaf Blowers anyway ! Lol
Thank you Tom. I have a ic7300 and you have pointed out some features that I haven't used before. Good Job de Roger w8rlp

i know it is pretty randomly asking but does anybody know a good site to stream newly released series online?
@Lennox Trey i would suggest Flixzone. Just google for it =)
Fantastic explanation, keep up the good work ;)
Thks. Keep up the good work. I fired up my new 7300 yesterday.
Congratulations on the new rig. I think you're really going to love it.
Hi Tom, thanks for taking the time to make all these video’s . I love my 7300 even more now 👍
I’m glad you’re enjoying the videos and the rig John. Thanks!
Very helpful, thanks!

My neighbors electric fence would drown my audio out if it wasn't for the NB. Works beautifully!

Thanks!
Firmware Update 1.40 is available
Don't know if I will every use noise blanker with the radio however I really liked the demo of it, will help on exam questions.
If you ever do mobile operation with it or if you use it at a Field Day or similar event with generator power, you might yet find a need for it.
Thanks for the comment.
