Thank you for clarifying Side Band. You mentioned there is a circuit that lowers the radio power-out signal if the signal coming back is too high. Is the correct name of that circuit the A.G.C. (Automatic Gain Control) and the correct term for the signal coming back in the antenna reflected power?
Reflected power is the power being reflected back to the radio; however AGC is a circuit that prevents you from over modulating the signal and distorting the audio. Internally there is a circuit which pulls back (lowers) the transmitting power(the watts) being transmitted in an attempt to protect the final transitors from burning themselves up when the SWR is too high (above 2/1). Some radios start lowering the power at anything above 1.5/1. That's why I recommend tuning to below 1.5 to 1. All the best and 73
Thanks again Joe. In less than one page of the article you mentioned I got it. I was going to guess that the Antenna system required matched impedance and FWD & Reflected signals be in phase. Actually, they are not in phase but are resonant in the antenna system. A very technical article but easy enough to grasp the concepts. 73.
Most beginners are not going to have equipment like this.. most likely they will have a basic HT, maybe a mobile radio. Still some good information though.
Joe very good job, how can I find the name of the Software you are using. getting ready to add equip have a ICON 7300 will this software work. Thanks Terry is it IOS
In "non-simple" terms the reason that final transiters are BURNED OUT is because the reflected power DETUNES the final amplifier stage of the radio and raises the voltage going to the final transitors- they get HOT and DIE!. For the GEEKS here you can read this excellent explaination of what is going on with HIGH SWR. It's not so much that you loose power out but more that you can destroy your radio by not properly tuning. Article by WC7I: www.hamuniverse.com/wc7iswr.html
So every time when u start hamming you have to keep tuning the antenna well that's boring what Happened to turning it go and go Instead of this extra crap. Dont get me wrong I thought haming and raging the chew, cw etc was to have fun not we extra work
Normally you do not need to tune a 2nd time unless you move way across the band. In my case I tune toward the middle of the phone section of the band and do not need to retune unless I move to the CW portion. Your mileage may vary-- depends on your antenna setup and how far you move within the band.
Joe Lalumia I see well I'm still going to follow ur advice get that Kenwood mobile radio but mainly will learn qrp and CW from the get go. So far I bought an book, I'm getting a mountain topper qrp radio and a straight key I want to focus more on cw at a distance on lowest power
A lesson for beginners.... Don't get involved unless you like nerds, old men and people who got there asses beat when young and try to make up for it being bad ass like behind the microphone.
What do you mean "people who got there asses beat when young"? Most of the guys in my club learned to use radio's in the military. Look, you do not have to like Ham radio and you are entitled to your own opinion, but so simply insult people.... says a lot about you... I hope you find love and happiness...
@@Man0fMeans Well at least now we're having a dialog. I have used 2M under an FCC carve out allocating 5 frequencies for use to one of the organizations that provides structure to the odd and arguably time wasting hobby of paragliding. As a career pilot, I have long since known the value of being able to use radio for communication. Recently I've considered installing a CB radio in a motorhome for garnering highway information, but am reading that it's not like it was in the 1980s...as a sidebar I started to learn more about HAM. All I can find however, especially when scanning, is people asking each other "Where are you? and how strong is my signal?". There seems to never be any content or communication other than talking about radios and gear. Believe me I could get on board with amateur radio if I could see that it had any value, but I may just need someone to show me exactly what that value is.
@@YankeeinSC1 Well get on the air and talk to people about what you are up to. Common sense, no? And of course people into radios and gear like to talk about radios and gear.
@@YankeeinSC1 You are WAY behind the times if you're thinking in terms of CB. You are apparently ignorant of the fact that radios are used to save lives and property when disaster occurs, from natural disasters, to manmade, especially when there are powere outages, and no cell towers are in operation. In between those situations, ham amateurs enjoy communicating with each other - so what is the problem???????????????? No, let me rephrase that - what is YOUR problem??????????????????
@@usernamemykel They've been saying that since the Civil Defense days of the mid 1950s. The first thing society furiously works to restore in the wake of a natural disaster is communication, then power, then water and food distribution. Hams will never have their "heroic day"... Just a bunch of dorks.
I’m studying for the tech license, and your video really helped me visualize many of the test questions. Thank you for sharing your knowledge.
You are welcome.
Thank you Joe...........I am a Tech class and this is great info.
You are welcome. 73
Very cool something to work for!
Excellent suggestions for a newbie like myself.
a trick : watch series on Flixzone. I've been using it for watching loads of movies during the lockdown.
@Orlando Grayson Yea, have been watching on Flixzone} for since december myself =)
@Orlando Grayson Yup, I've been watching on flixzone} for since december myself :D
@Orlando Grayson Yea, I have been using flixzone} for years myself =)
What software is that on ur screen?

Just subbed to you Joe....Very nice channel.
73 & MABUHAY!
Thank you.
Great explane 73 from S56PAC
Thank you.
Joe very good job, how can I find the name of the Software you are using. getting ready to add equip have a ICON 7300 will this software work. Thanks Terry
is it IOS
No it runs on Windows 10.
Hi, just caught your channel today. Looks real neat, I like your shack, thumbs up! 73, KC3BXZ Joe
Thanks very much. 73
Very good video

Thank you.
Wait! We forgot to demonstrate FM, SSTV and CW!
Thank you

Thank you. I will read the article. It sounds like you are saying its related to mismatched impedance.
likley a beam directional antenna
Playback speed 2x

@@nikosadie And I hope that he finds a way out of his cave of ignorance.
Good God what a useless hobby
As opposed to flying around in circles wasting time, gas and the safety of those on the ground?
To each their own, buddy
