9-24-2017 Just decided to become a HAM. This old Virginia grandma has started Ham College. So glad to have found you.
As someone who is studying for my technician's license, I want to thank the both of Ya'll. Keep doing what you are doing and you will have a fan in Houston Texas! Cheers, Brothers!
Guys, this was great. My first "youtube" taste of amateur radio and I found you guys. I'm trying to apply this to a math class I'm presently in which emphasizes symbolic logic and circuitry. It has always fascinated me since childhood how wires, bent around and contorted just the right way, with current running through them, could produce and receive wireless communication! Thanks again.
thanks for these vids, have listened to ham conversation and weather spotting on a scanner over the years and finally decided to join in
New to Amateur radio, this is so helpful! Thank you for it!
hello the names peyton,
im 16 and I've been doing this for just about 4 months, I plan to upgrade to general soon. I plan to go through all the episodes. I would like to thank you for making these videos, I am planing to upgrade to extra class very shortly
Thanks for continuing this show.

Thanks for the videos. They're really helping.
great idea ! Well done !
I love this channel
And youre right about the Leyden Jars. They are like early capacitors. They were charged up to almost discharging, then the 2 connections shorted to provide a spark/burst. A leyden jar burst can be heard set off another fully charged Leyden Jar across the room. They then put brass conductive rods on the tops of them and it acted as the first antenna. The old circuit you showed off Wikipedia is strong enough to charge them....but you were right in asking because it is odd that a spark-gap and Leyden jars is used...
I reckon the spark creates the Alternating Current needed to charge up the Leydens. I dont know if perhaps aswell....the spark is then Amplified through the Leyden Jars...allowing it to traven further - ship to shore or rooftop to rooftop!
Thanks Guys....I made the relay Morse Key! but I must say I struggled with trial and error of the exact wiring (dont mean a schematic) Got there. I ended up making a MKII with a ready maderelay switch (12V radio relay with a coil and metal arm inside) Got it to simply switch ON/OFF, but then I used your relay wiring method of cross wiring to get it to BUZZ!!!! Not got the freq yet and I couldn't get it on my FM recievers.....BUT then I hooked up a little switch and added a Copper Wire Antenna to one of the relay pins. Then....I made a very fine gauge coil and when the coil is over, or very close to the antenna I pick up a reading on my digital multimeter!!
Thanks again. I am self-studying for Foundation license here in the UK and I love you're videos...Very interesting
Anyone interested in some photos of the one I made - and the way I did it with the parts etc let me know....All of it was 0 cost and with bits laying around the house!
The Pilot episode is at ua-cam.com/video/XhtMxz-BLzo/v-deo.html
Awsome show..
as always guys excellent show!!!! Love those bloopers. - Kilroy - KF5RFG - 73
Thank you KC2AVV
We're gonna have to strike a trot!
Q can i use the 10 meter ham band with a CB car
ed
Great show, keep it up and 73...wd0akx
maybe what he ment by Elmer is (like glue) help you stick together or stick to the art of ham
I was a happy fellow when I got General after being a licensed ham (old Tech Plus from 1981) for over 20 years ... and thanks to the VE's that tested me there. And was about fit to be tied with happiness when I got Extra in 2011 in Davie, Florida and again thanks to the VE's. And I have another little story, talking about VE's, to tell. I had to go VE shopping just to be able to take the Extra Class test. I went to one club all dressed to kill and they didn't have enough Extra Class VE's to give the test. So I had to exit that facility with my tail between my legs. I won't mention any names or club names but this does highlight the need for not just VE's but the Top End VE's capable of giving he Extra Class test. The story obviously has a good happy ending as I did pass the Extra. I still have the CSCE - The Certificate of Successful Completion from that test. If I remember right you can actually operate at the privilege level of a just-passed test while waiting for either the paper license in the mail (and I understand the FCC may be stopping sending those!) or seeing it on the FCC web site. This is where you have to use something like your Call Sign plus "interim AE" for extra or "interim AG" for general. Anyway having just passed a test and having that CSCE is like a Kid in a Candy Store. At General Class you just got most of the H.F. frequencies to operate on - where as a Technician Class you had just 10 Meters? And at Extra Class you just went from some to all of the available Radio Amateur H.F. frequencies. It's just a fantastic feeling!
Also ... this is Two for One ham radio stories day. If newer hams care at all about getting operating awards, like the coveted ARRL DXCC (100 countries) or WAS (50 states), this is quite possible with even modest means. I did both and over 90% of it was done with 100 watts only and modest antennas. OCF dipole at 30 feet and Ground Mounted Trapped Vertical.
One thing I learned is #1 you might not start off trying for 100 countries or 50 states at all, and #2 it may take a couple or a few years to accomplish it. And it may happen ALMOST by accident. If you log with Electronic Logging sites like www.eqsl.cc or the ARRL Logbook of the World (LotW) [and now the www.qrz.com logbook system] all of your contacts are recorded for ever. I happened to choose eQSL for about 4 years. I still don't have 100 countries on there.
But I was very pleased to BUST A MYTH that you couldn't use that eQSL credit for a LotW based DXCC award. Quite the contrary ... you actually can! By downloading an ADIF file from eQSL and Joining and waiting for the code by mail (patience .... patience!) you can upload that ADIF to LotW. They will in fact give you credit for Some Years of ham radio "work" by matching up all the contacts in your log with other LotW users. For me that meant 114 countries and 50 states. Never Say Never! As this kind of thing can happen in few years of operating .... just turning the dial on H.F. ... and working stations for FUN. And One Day you find yourself with those coveted Operating Awards such as DXCC and WAS!
[edit] Oh, and I forgot to say ... It's a new thing that the www.qrz.com logbook thing (which is All Grown Up by the way!) now has AWARDS! But not only that but for FREE you can download from LotW and get the same credit on QRZ that you got on LotW. They have some nice awards ... and since pretty much everybody looks up contacts on QRZ - you get nice little award stickers or banners or whatever they call them by your picture on your QRZ.COM page. What's not to like about that? I would recommend joining at the XML level as a paying member - to support the system ... as well as to get full Log Upload and Download capabilities.
I actually made a joke to a local ham here via email about a new award for Working All Electronic Logging Systems. :-) Now that's funny! :-)
Correction ... and it doesn't seem to want to let me edit anymore - it goes to forever "POSTING" and never finishes. You do have to wait for your upgrade call sign info to show up in the FCC ULS database.
If you were unlicensed when you passed the exam, you can't go on the air until your new call sign shows up in the FCC database.
If you already had a license you can use your new privileges immediately. Use the appropriate call sign suffix when you’re transmitting in a frequency segment not permitted under your old license. Use /AG if you’ve upgraded to General, and /AE if you’ve upgraded to Amateur Extra
Could you Please post a link to the preview of this series? Thanks and 73 KM4AOF
@57:00 -- I thought of a good example: sending CQ using cw (or anything else I suppose), ex:
cq cq cq de [callsign]
"at the beginning" seems to apply to this..but technically not the first data sent.
Does this mean you don't have to give your callsign for the first 10 minutes after you start transmitting; and/or do you have to give it when the transition is made from 'broadcasting* to find someone' to '2-way communication*' ?
Great stuff guys, thanks for making/posting.
+Andrew Buckau According to the rules you must ID every 10 minutes and at the end of your communication. It does not say you have to ID at the beginning, but it's customary to do so.
Amateurs are never allowed to 'Broadcast'. Although there are bulletin stations which blur the lines on this.
+AmateurLogic.TV Thank you for the quick response. Makes sense.
Yep, sorry, just used the term 'broadcast' because until the other person sends a reply..technically it was 1-way communication (?)..which leads to my next question:
Another edge case, but... what if I call CQ for more than 10 minutes and nobody replies..do i still have to put out my call sign? "every 10 minutes" seems pretty clear..: Is it 'every 10 minutes' of transmitting*, or every 10 minutes of 'communication*' ? same thing? - do we just pretend it's not 'broadcasting' because it was done w/ the intention of establishing communication?
edit: this is talked about around @58:45, but I didn't quite get it -- he used the word "communication", as did your previous response..so I guess, yes, you'd have to ID after 10 minutes of calling cq (without any responses).. ?
Again, thanks. About to watch the next episode.
+Andrew Buckau you must ID every 10 minutes and at the end of your communication(conversation). Once you make a transmission, you must ID every 10 minutes even if you only transmitted for 1 second during that 10 minute period.
If you are calling CQ then you are calling for another amateur to answer. This is not broadcasting. However you cannot make one way transmissions intended for the general public as that would be broadcasting.
+Andrew Buckau you typically include your call in the CQ call.
CQ CQ CQ this is MW6TYD Mike Whisky Six Tango Yankee Delta MW6TYD CQ CQ CQ and repeat.
Occasionally I include the band e.g CQ 20 metres in my CQ call as it helps folk who monitor multiple bands on their sets. So if you're calling CQ for 10 minutes you'll say your callsign plenty.
Being from the UK there is no requirement on me to broadcast my callsign every 10 minutes, our rules are whenever feels practical. So having a natter with a friend locally on VHF its usually said at the start and when other stations join us but otherwise its a flowing convo. Having a QSO on HF its more formal so I'm pretty much stating who I'm talking to and who I am every over. E.g. "KG7VOA MW6TYD returning, yep copy that weather here is... Blah blah blah... Over".
So how do you call out to see if any other hams are listening? I thought that to establish a 2/way connection you have to call out to 'everyone' and anyone who's listening
The 18", dual band, whip that I saw you guys offer somewhere once for around $20 USD; Can I please get the details for ordering. Thank you! Great Review shows btw. :) 73 de 4Z1CQ
keep up the good work i think you should do this more but the pool updates every 3 years or so so kind of hard to give information on the question pool.
I want to buy an icom radio now.
I couldn't find the pilot at first. So if you are looking for it:ua-cam.com/video/XhtMxz-BLzo/v-deo.html
I am a new HAM less than one year. I will certainly watch this series. Not sure if any of the future video mention this bit of radio history but please take a look at this. explorepahistory.com/hmarker.php?markerId=1-A-3A1 I also agree that Elmer's are a badly needed resource. 73's KC3FKX
Where are you boys located? Criss (KG7TWM)
Criss Rosenlof we are near Jackson, MS.
What are the rules, written or unwritten regarding politics on ham? Could I run a "show" about current events? I'm guessing no..but just wondering.
The unwritten rule is you should not discuss politics on Amateur radio. You can't run a show on Amateur radio since broadcasting is illegal.
@@AmateurlogicTv Thank you!
Dose the HAM test hard?
+ping415 The Technician exam is not really that difficult. Go to hamstudy.org and check out some practice exams.
In the UK our Equivalent is hamtrain.co.uk and what the US call Technician, UK call Foundation (Foundation/Intermediate/Advanced). The RSGB, and OFFCOM are like the official organisations. My foundation exam is going to be £20 and my neasrest local club is like 2 miles away - where I will sit and prepare for the exam! Also doing a free online course to help prepare for it, starts early September. I know they say its not difficult to pass if you can remember the book but I want to learn as much, and its all free so why not?
Gentelmans, do u have any script or sceraio of Ham college? It would be great to receive it. I would like to translate it to russian and ukrainian language. 73 de UT4UMZ
lemmbitkuzin Sorry no script. We do it live with just a rough idea of what we want to say.
Can you also add some questions for other countries exams as well, such as questions for the foundation class license in VK? here are some questions. www.radioactivities.sa.scouts.com.au/training/foundation/trial_tests/trial_test.asp
We have discussed this but have not come to a good way to do this without confusing the potential US Hams we are currently tutoring. We do have a few ideas though and that may be something we tackle in the future.
Much of the technical stuff we will be covering is applicable anywhere though.
HOW OLD CAN YOU BE
Evan Dickens , There is no age limit. You can be any age to become a Ham. Some schools have Amateur Radio clubs.
THANKS I WILL BE IN 7 TH GRADE NEXT YEAR GO HAMS
+Evan Dickens Not the youngest by far! There is a 9 year old and a 12 year old who have made worldwide contacts. When I was in 7th grade I was very much interested in radio communications, I didn't have the internet like it is now (wow I feel old now and I'm not even 25!) so I had no way to learn easily. Join the hobby! 73! KD2KKH
One 2 year old took the test but he got scared, started crying, and his mom had to take him out because it was his first multiple choice test
I got mine when I 12 yrs old. You can do it!
water pipes for cooling. that baby would be hot.
