I love your radio enthusiasm. I am not even a HAM. I am a c.b. guy but your videos make me want to turn my computer off and go sit in my radio shack for the rest of the day. Please keep up the fantastic youtube channel. Know this. If I get my HAM license it is because of your videos.
awww man thats so cool.. All i hope is the viewers get something out of it, whether it is focused on CB or ham, but you are the reason I am here. Thank you so much for watching, 73
I think we're getting into "pretty damned cool" land when you get this low on the spectrum. I respect people playing with this stuff. When you think about the width of the band and bandwidth of the signal to other bands, this is amazing! I'm glad you put this video together, and now I'm going to see what the 4000m band looks like, lol!

Hmmm, 2200 meter Ham Stick anyone?
Eric, thanks for getting into thinking out of the box. Like to see something new and interesting. I appreciate your efforts!
Thank you, Sir. I always learn something from your videos, no matter what the topic is.
I learned something today. Thanks for your efforts, they are appreciated.
Eric thanks for the video on 630 Meters ! You gave me enough information to go over and try and receive the WSPR signal on 630m...something new for me, I decoded 3-4 signals at 500 miles in just a few mins. Learning and trying new things on ham radio YEA ! thanks for your help.
Great job on the video. I finally understand these new bands. Thanks.
Thanks for the informative video Eric. I learned a good lesson about a bands I did not know about. I like the challenge of building a antenna and trying to pull the weakest signal in that I can. I now have a new challenge thank you 73
Good info, thanks for sharing your takeaways! I appreciate that you acknowledge it's not for everybody, but that it's still worth knowing this is out there and people are playing with it!
Wow eric you ro c
Rock, will the newer 7300 coming out tranmit on those frqs? Your scary smart see yah ki4 luy night.
Well done Eric. I'm a very new ham, so much of what you are talking about is beyond me right now, but I appreciate you putting the information out there. Unless you (or someone) does these videos, guys like me who are new and have no Elmer's to help would be clueless.
Thanks for this very good basic intro to these bands. Keep it up. Hope to see / hear you on 630/2200.
Great overview! Thanks for the look into it.
Very interesting. I haven’t studied the bands yet. Great information. Thanks.
Love the 2- ICOM 7300 radios side by side. Thought I was the only one that liked 2 radios. Thanks for the info and making it simple for this old boy.
Well done good and faithful servant. W6COP steve
Thanks for the info, never heard of these bands
Interesting content, especially as a WSPR venue. I enjoy your videos, Eric! 73 de KM6KLV
Right in there with the Longwave Broadcast Bands from Europe that, with the right tuned antenna, can be heard in the eastern US. Navigation Beacons as well. As always great informative video Eric. 73 de N4WRW
Eric you have had a very Eclectic Week from lunar rovers to 2200m antenna designs, its all gd, as most of yr subs are technucally minded individuals and Im reasonably certain we all share at least some interest in yr chosen subject matter of the day, cheers Eric, all the best from A9 Land, 73s keep the vids a comin'
@HamRadioConcepts Hello from M0VCX in UK, I didn't know that information about the power lines is transmitted in that manor. Just as I didn't know about 630meters or the 2.2km band so thank you, thumbs up:- 73
Great video, very informative
Great info packed video !
Nice video, thanks! People interested in operating on those low frequencies should first surf the body of info posted by lowfer operators.
Nearly all of them use home brewed impedance matching and put in great effort to reduce losses.
Low freq ops are a great way to learn about efficiency and eliminating things that hamper reception of weak, narrow signals.
Great video! Only thing I know about 630 and 2200 was that there were two tabs on DX Maps for them. Until just now. Thanks Eric!
That is rewarding to know it does educate LOL
Eric, thanks for reminding me about these bands! I just might give at least 630 meters a try. 73!
good video Eric. the frequency to monitor is 474.20000 and the use JT-9 down here.
Enjoyed the video.
I heard years ago about 1650 meters. It was a "Radio Electronics" or "Popular Electronics" project to build a transmitter for the band, I believe It said ANYONE could transmit on the band, but the limitations were weird. The combined length of the feed line and antenna for the transmitter were either 50 feet or 50 meters not sure now. The article had a wire antenna directly off the back of the radio so that none of the combined length was wasted as feed line an you could have a full length use as an antenna. The radio was mounted outdoors on the tower, pole or roof top, with the wire antenna extending from there. There may have been two articles one for a transmitter and one for a receiver, but I actually think it was a transceiver.
If I remember, their solution feed audio up/down the coax (can not remember if the "audio" was straight audio or an IF signal), while sending variable DC up the coax to run the radio. For example a minimum voltage, enough to run the radio not sure what the voltage was, but lets say 5vdc, then as you increased the voltage to maybe 12vdc would be regulated the operating voltage while another circuit tied to the unregulated incoming DC voltage increase or decrease the voltage sent to a "voltage controlled oscillator". The "radios controls" with it's audio amplifier section was a separate unit in the shack with a knob controlling the voltage sent to the radio in order to remotely tune the voltage controlled oscillator which tuned the radio.
The article may have have specified a coax with another conductor that controller transmit/receive. Hell for all I remember it could have been a single variable voltage with polarity. Positive voltage sent up transmitted, and negative voltage received. All you needed is a capacitor to maintain power as the transmit switch went from one polarity to the other, and a bridge rectifier. The negative output of the rectifier is tied to chassis ground. The positive output to the capacitor (to maintain power during switch over and to the voltage controlled oscillator. one of the two inputs to the rectifier would power regulator for the receiver and other would power the regulator for the transmitter. As I say the article is vague in my mind. It may also have been 1450 meters but I have seen articles on 1650, so I think 1650 meters is correct.
I do not remember what mode it received but I do know the received signal was sent down the coax as audio, maybe a BFO for CW, or it received AM? It was a very simple transceiver and I assume it shared an oscillator between transmitter and receiver. Any one know about 1650m?

All good information thank you
Heard you on SarNet today - fun to recognize a familiar voice locally, one I've watched on UA-cam. Often monitor the SarNet network - KN4RBO.
I am in boston NY with 7300, I can receive the longwave but I get a lot of QRM during the day . mostly from AM broadcast band up to around 24 Mhz but pretty quit at night. mostly because I have solar with MPPT charge controller. I need to make better antenna . just using a loopstick for long wave and not getting any reception outher than QRM . sometimes I get beacons from airport. great video with info and links.
I like the idea of collecting data and learning from it. First video I’ve watched on LF.. Studying for General now
Right know, probably the best bet for transmission at those frequencies unless a very specifically built homebrew, I'm guessing is going to be an SDR transceiver.
Eric I really like your show but u hate the fact that everytime you show something i wanna buy it. #broke
Hihi. Eric in VT
I do WSPR on 80m-10m, and hope to be getting on 630m soon. Seeing where I get signal reports from is really great.
I live on the west coast (California), and I've had my WSPR signal heard as far north as Ellesmere Island (Arctic circle), and as far south as Antarctica; as far west as western Australia, Japan, and China, and as far east as Finland. All on 200mW of transmitting power going out onto a dipole.
I Looked at the regulations that apply to the 2200 meter band, and they gave the user the opportunity to run substantial radiated power, (5W) EIRP power, but were far more limiting than the free LowFER band on 1750 meters. So if someone wants to play around on Longwave, they are well advised to ignore the 2200 meter band and get on the LowFER band instead. My 8 mW EIRP on 1750 meters blanketed 1/3 of the USA day and night except during summer afternoons and evenings when lightning storms would turn the band into a roar. Communications at those frequencies are essentially acting like line-of-sight signals due to the bending of longwaves by the atmosphere's pressure differential with altitude operating to refract the signal in a curve around the planet. I had a friend 150 miles away in Wyoming who I would send slow, repeating text messages to each day, and receive replies from the next day. I enjoyed the hell out of driving my car from Colorado to MI and copying my beacon and the beacon of my friend in Wyoming as I drove nearly 900 miles before they started getting intermittent.
The thing to understand about the radio hobby is that it's not just 'super-CB' radio. It includes all sorts of things one can do, from Earth-Moon-Earth communications and radio-astronomy to designing and building your own gear, (if you're a LowFER or a ham.) If your only interest is talking on a radio, then stick to CB's, and "Breakity broke 1 9er," to your heart's content. But if you find it interesting that radio waves do such amazing things around the world and the universe, then find an Elmer, (a mentor,) and dig in.
I am, at present, not really interested in either band/frequency, but your video was fantastic. Your voice is super pleasant and easy to listen to. You sound like you're from the Northeast? NY/NJ area ? 73
Thank you for the information! I was curious if there was any activity on these bands. I don't have the space to have an antenna suitable for playing with them. Also wasn't sure what WSPR was. I appreciate your explanation of that as well. Thank you for your work on these great videos! 73, de K8KNX
Bom dia galera do canal Hamradioconcepts Adorei !!!
FYI, Rig Expert (which makes a way better antenna tuner than MFJ) makes a couple of antenna tuners that will go down to 60 KHz, which will cover both 2200 and 630m bands.
thanks for that DXMaps.com site!!! holy!!!
Very informative video. I liked the format, I don't recommend this all the time but for something like these new bands it works to efficiently get the info out. KN6FWT 73's
I remember 160 band being this 'how the hell are you gonna get antenna space. The club station had 80 meter andi saw the size of that antenna.
so.... these bands feel insane to get anything going for.
Thanks for the intro. Another reason to get active again.
K2KQU .
That 1 watt performance is ultra impressive when you consider the foot long sparks and kilowatts that Marconi originally used to get a LF signal to travel those distances.
James Bowie I was thinking that. I have some Modern Electrics magazines from 1911 give or take. I got them 40 years ago along a sparkgap transmitter and receiver . I didn't try to use it for safety concerns. In the end I scrapped the transformers.
I tried lowfer (160khz) and barely got farther than my back yard fence.
even worse than 0.5 watts on the FM broadcast band.
PS your rigs will transmit with the modification down to 100Khz short of that negative. Below 30khz is US Navy submarine transmission. 73's
what is the black box "compatible digital radio protocol" ?
A few months ago I was wondering how the 2200 would do on a boat. Use a coil for half and string a line behind your boat. A very slow moving boat.
Eric was in the camping area at Wal-Mart and ran across freeze dryied Neapolitan ice cream sandwich and busted out laughing!
HAHAHAHA
I won't be using those bands, no equipment for that, besides having a noise level of about S9 across all my HF bands. Trying to decide if it would be worth my $$ to get something like an ANC-4 to try to minimize that noise.
I learned something. now to string 2000 feet of wire around my 2-acre lot and try transmitting... okay, maybe not, but very interesting.
Thanks!
KD2QXQ
very interesting
Coherent CW (CCW) would lend itself well to lower power like this.
Thank you for the awesome information! I would love to try this one day... Phone though? Did I see it wasonly 1khz?
It just hit me why we have phone privilege on it! Most RF problems were solved by experimenting hams! They are looking for a phone solution that takes up less than 1khz! A challenge has been issued!!!
What kind of, "leave in" in-line antenna tuner/analyzer would you recommend for someone just getting into HF and mostly using it Mobile (large SUV)? I want to leave it in line in case I have a sudden change in the antenna (say road damage or weather incursion type) so I wont damage my finals? Ive read to many negative reviews on MFJ on their QC.
Icom Ah-4 tuner is a good tuner and its automatic
I'm not sure wspr functions on psk reporter as no wspr is showing on any band
mag loop antenna would be best at those frequency's as the interference is hi!
so why would the fcc bother to move allocations like these frequencies to amateur use ,especially at such low power that we could never honestly use it effectively.a very small percentage of us have that kind of property for antennas of that size...then they will say were not using our spectrum,and in the window of opportunity, take those and others that are deemed not utilized...I'm all for extra bands but we've got to be able to use it realistically. Great video tho
Assuming the power matters is your first mistake, second is that you need to string up a 2200 foot antenna for 2200 meters. I'm radiating way less than allowed on a 43 foot vertical and still getting reports from Europe and Russia on data modes.
Love how you are always trying new things. DE WA1KLI
Nice.
It’s hard to imagine a 550 meter 1/4 wave.
I don't understand how with a 500w amplifier by the time it leaves your antenna it's down to 1w?????
I’m not sure what you are asking? That doesn’t sound right at all.
@@HamRadioConcepts well you said that in the video And after watching your video I did some more research on the 630 band And apparently with the 630 band you need a 500' antenna or something like that at and lots of things even the slightest change in temperature or wind could throw off the tuning of the antenna And I guess because you have so many windings and such a big antenna I guess you lose a lot of power by the time it gets out the antenna I really don't know I'm kinda piecing things together and guessing
Fun vid! 73, W6LIP
Hell of a deal.
pskreporter doesn't usually accept reports for wspr. Use wsprnet.org/drupal/wsprnet/map instead of pskreporter for wspr reports.
Very interesting. However, living in an apartment, I thing I's be evicted if I tried stringing that kinda wire arournd!
Very thin black wire and nobody will even see it. My EFHW has 210 foot of 14 gauge black and I cant see it standing directly under it.
What's on 4,000 meters?
AFAICT it was a UK amateur allocation from 1996-2003 when it was replaced by 2200m
Did they take 2m away???
no
@@HamRadioConcepts that's good!
Next 5000 meter band quarter wave would be 1250 meters long
Who makes a radio to transmit there? Exactly
If you make a video about a paperclip I’ll watch it.
I often had plans of making some weird random pointless video just to see what everyone would say. I think I might just do a 3 minute review on a paperclip to see what happens HAHA
ua-cam.com/video/bLhHx_LYaCQ/v-deo.html
Speaking of paperclips, back in the 50s, my dad decided to make an antenna out of a paperclip chain. Worked a guy in Seattle from St Louis.
Philip Muth WØRHP I was thinking of suggesting the same thing! Lol
HamRadioConcepts I’m that guy’s third subscriber!
Cool video

This makes me want to build a jammer.
I require important science. Can you receive it on your lawn chair dipole?
Don't have one of those so I couldn't tell you HAHA
@@HamRadioConcepts I am sorry it was HamRadio Crash course I was thinking of, but if you decide to build one you can let us know :)
Just roll out a couple of rolls of tin foil. Vwalla a 630 meter antenna !
You know .. VK3YE Peter Parker has a way of coupling light poles to get them to transmit on the low bands. He actually raps enameled wire around super tall metal structures to resonate on different bands. His “more Qrp Antennas book” talks about it. It was $5 on Kindle. Great book so far.
I like your call sign mine is KE0WOQ
Who wants to build a 2200 meter beam?
I have heard there is an 8 meter band petition in the works. It probably will not be implemented. Not being an amateur radio operator myself, this may be just be Internet babble with no true backing on a petitioned 8 meter band. .
Oh boy two more bands that nobody will Ticon because the equipment cost too much and it will become nothing but a click for the rich
God this is boring
