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! 73 KD9TEM
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.

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!
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.
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.
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? N3PLA (Amateur) WRMB762 (GMRS)
@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
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!
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'
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 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 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
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.
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.
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
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.
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.
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 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
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.
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.
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.
@@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
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!!!
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
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.

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

It’s hard to imagine a 550 meter 1/4 wave.
