- Jim W6LG has been on the long path since 1964. Jim shows how that works using G4ELI's, Simon's World Map program. A wonderful program that can be a real asset in the ham shack.
Here's the address of Simon's website: www.g4eli.com/world-map
Scroll down the page to the bottom where there is a link to a drop box. There is now a newer version with several improvements. Again, this program is excellent. - Наука та технологія
I love working the Greyline. My most memorable Greyline contact was 15:54UTC on Dec 31 2017 on 14.200 mHz. a guy
near Sacramento California called Jim. W6LG. he made great UA-cam videos that helped me get all my licences. Matter
of fact he's still making great video and I'm still learning lots! 73 Jim, form Tom G2NV. I was M6ONV back then. Hope to
work you again soon.
Brilliant! Simply brilliant thank you.
Jimmy, I just now got to this video, and I immediately downloaded the program. I then watched carefully to what you did, and then did it myself...Thanks again..N2QFK
Super job presenting this, Jim. TU!
Jim, thanks for explaining "long-path",. With over 50 years at this hobby, I still seem to learn something new. 73 de Chris W6NOB
Me too! Thanks, Jim
Another great video, Jim. I never heard of this program before. Thanks for bringing exposure to it. Very useful. This is the best explanation of the gray line and long path I've heard. Seeing it visually really helps me understand it better. Hope you're feeling better. 73 de N6EF
Grey line is amazing. I had a QSO with a station in Japan one morning from western Pennsylvania. I was mobile with a 20 watt radio and a hamstick antenna. The station in Japan was 59 and I got a 57. We were both amazed at how well we were hearing each other with my set up.
Thanks Jim for the information. Love the Simon world map ..a must donate for sure thanks insight
Thanks Jim. Now Grey Line makes sense to me.
Awesome. Thanks for all you do. 73.
Hello Jim, really enjoy your videos currently live south of you in Bakersfield and I’m studying for my technical. I honestly got into learning HAM radio just looking for a hobby. Back when I was 15 I had an old Realistic radio and a whip antenna on CB really enjoyed the hobby and got to speak with lots of people to include Argentina. Hope all is well God Bless.
Good stuff Jim! Thanks for posting.
Thank you Jim I had no idea about the long and short path. Thank you very much for the info. Fingers crossed to work you one day. I am a qrp op.

Great video Jim! Thank you.
Thanks so much for this!!! What a brilliant explanation of grey line 👏 worked 4x vk stations all grey line last wk from uk using 10w and a hexbeam:)
Excellent video Jim, very informative.
Thanks Mike. Nice to have a QSO with you this morning. 73, Jim
Great story Jim. Thanks for sharing! Hope you’re feeling better.
More good information that was well presented.
Thanks Jim
...thank you for the reminder of the long path! ...i really appreciate your channel! 73 de AJ4D
Awesome video - thank you!
Thanks Jim, I'll be looking for when the stars next align and the grey line into California is all lined up with the long path to you from New Zealand ( ZL) and your morning routine, Just give me some time to make a strong espresso coffee before you lift your antenna.Regards and 73's Kris
thanks jim another great video your the best elmer there ever was...the grey line is a great subject to talk about the long path can be a fun but challenging task but so worth the effort ...take care H.Thomas in north central missouri 73
Jim, Thank you for showing and demonstrating this software. I just downloaded it, and looks to be very useful (or at least very cool!). 73, Jim
I’m from Sri Lanka,my cll zine is 4s6ph,good job❤
Great video jim keep them coming Jim thanks for sharing Ted KD2ARD
Thanks for sharing. Sometimes I pull all nighters in the shop and it's funny with just a dipole how the dx changes when just listening to chatter and not surfing the channels as the time changes.
Great explanation of the magical “Gray Line”. 73

How did you know what I was wondering about? Gray Line and adjustment of Simon's World Map in one video. You are a mind reader!
Quite often sit and listen to you guys, Mike, Peter and the group. Have had a qso with Peter but never been able to break through to the US on 20m, hopefully that will change this december. Planning on building a directional 20m antenna for December whdn propagation to the US is better.
Hi Jim,
Hope you are doing well. Excellent video. Very well explained long path. I didn't know it was not 180° from the true bearing. I have a yagi with three elements on 20 and five each on 15 and 10. I guess with it's beamwidth, I could just point 180° from the true bearing and the long path should be within reach. I downloaded Simon's latest version 1.3.3 and will get it installed. You and your family stay safe. 73 WJ3U
Thank you Jim, super hint, we already made 4 contacts very 73
Good morning Jim I watched your video last night quite interesting. Unfortunately I do not have a beam but I download Simon’s world map and that is an awesome program. Thank you for sharing.

Very good pointers I have done that through the years but never seen anything in print about it. One of the things you learn after getting your license. A little different than the gray line
Jim, great job! Simon was the original author of HRD. I use both this Map of his as well as his SDR Console to drive a couple of my sdr receivers. Great developer! 73 de K4FMH
I did not know that. All are excellent programs. As usual, thanks for the education Dr. Howell. 73 from one of your humble students, Jim W6LG
So interesting... when i worked at at&t in dayton*, many years ago, there was a guy that told me he was one of the first to send a signal around the world i guess around the 1930's. I had assumed a lucky shot of ducting... thanks for clearing it up for me. Iwish i could remember his name but that almost 40 yrars ago.
Hi Ed, I have a vague memory of a W8 who was working the world with a directional antenna that had a wood boom and conduit for elements. I grew up with some very famous ham who were operating before there were callsigns. That included 6DD, 6UP, 6PL, 6AM, W6DD, W6PL, W6UP, W6AM, W6BQW. W6AM, had one of the best locations in the U.S. He also had big, BIG, amplifiers with direction antennas that in many cases were wires; like rhombics. 73, Jim W6LG
Jim, after watching this and thinking about it I leaned what the Gray line means. Presently I am adding a beam to station and I will try this and use it to get contacts. I am not sure it works as well with vertical antennas but I will try it until my tower is finished.
Hi Jim I'm glad you you're welcome back how do you feel are you in good health also have a Happy Thanksgiving to you and your family and be safe for the holidays
What a great DX having worked that mother and daughter team in different locations in Germany. This is why amateur radio will always be magical.
Jim I have 3 questions I've always wanted to ask and learn from you.
I wonder, if you had worked them in the short path would their signal have been higher and how does one know your signal is actually traveling long path instead of propagating via the back of the beam? (unless you have a mountain blocking your easterly direction as you had in Burbank)?
2. Why work long path at all, for the challenge? I think it's fascinating if you can't work them in the proper bearing.
3. Finally Jim you are a masterful video editor. A person such as yourself that has seen so many decades, are you as amazed as I am at the technology we have today at our fingertips? I wouldn't have dreamed of having radios that can do what an Icom 7300 does, and the world so connected, easy video editing, zoom conversations, etc.!
Thanks for being an elmer to all of us
1. Probably not at that time of day.
2. There is less noise and less QRM. Getting through the east coast can be very difficult.
3. Not really, but I am learning. My father, Desi Arnaz and Danny Cahn were the first to use 3 cameras and film the show like it was a play. He was an editor then and later an executive on many TV shows that included Star Trek. Bill Heath and William Shatner hated each other. Ditto the hate with Gene Roddenbury. 73, Jim
@@ham-radio Oh that Bill Heath! I'm a nobody and even I know that name. The list was and still is huge on the dislike of working with William Shatner. Fascinating stuff. Thank you Jim :)
@@ham-radio You really should vlog all of this on UA-cam for posterity!
Hi Jim, my name is Bob KC6SOT. Long time follower. I find all your videos very informative but the last one is a bit confusing. I would like to learn more about long path and gray line. My current antenna is an end fed halfway with the feed point at 25 ft. I know this isn’t your favorite antenna but I live in an HOA and it’s what I have. Don’t think I can take advantage of long path QSO with a fixed orientation of my antenna. Keep up the great videos.
Bob KC6SOT
i have a question about long and short path . on DXWATCH is the bearings they show for a station the long and short path bearings???
I suppose the best antenna for utilizing the ‘grey line’ is a directional antenna. Am I correct in assuming this?
What type of mast ?
How does it work ?
Jim, The first question has nothing to do with the subject, but I have to ask you, "How many Drake L4-B linears do you own"?.
Now regarding the subject at hand, is this a program for wave propagation and theories or is it finding shortcuts to other regions around the world for antenna signal directions???. I the website via the link you provided and I'am not understanding how to download or how to use the Grayline system.
Great show as always, thanks for reading!
Three at this time. I have owned about ten.
It is a map program that has the gray (grey) line. It is a useful tool in the radio room.
Do what I did in the video and then play with it.
73,Jim
G'day Jim
Hope you're well mate.
I wonder if short path can be on the same side of the grey line then? The reason I ask is, I've had experiences where stations in Alaska are very strong when it's dusk both here in vk2 and in Alaska. The time here is 530pm and 1130pm in Alaska. I wonder if that's a real phenomenon because when it's there, Alaska are well over s9 here. Cheers Aaron VK2ON
Why did you move from wolf mountain ? I loved those videos and location was good ? Thanks
I have cancer and need to be close to the Kaiser Hospital and my oncologists. 73, Jim
@@ham-radio Oh sorry Jim i understand. Im taking my foundation exam saturday 26th november here in the UK im age 45 and first used CB radio when i was age 15. Not used CB now for over 20 years and feel i would love to own a proper HF setup so looking at a icom ic 7300. i do like the look of the old yaesu ft 1000mp but not sure about that as they are very old now and dont want a first radio to have issues. Hope you stay well for many more years and enjoy your radio for many more years . i wish you well
for a true challenge try a omni directional vertical antenna
For an intro to gray line propagation, using Google Earth would have been better.
Younger hams probably weren't taught the severe distortions introduced by the various map "projections".
If you think so, then do it and tell us all how you did it. I have no idea how to make that happen. Thanks,JIm
So how do you know you worked long path rather than just working off the back of the beam ?
Well, I point the beam from SW to West depending on where I want to talk to. SW for Europe and West for Africa. Signals have a distinct flutter. Guys in Africa and Europe are pointing into the long path. That is in the morning my side of the world following the grayline. And that is the clue. I listen with the antenna into the grayline twice a day at sunrise and sunset.
I was taken by ambulance to the ER because I needed emergency care. I am got out yesterday. 73, Jim
Hi, this was a great video as always! Please allows me to ask a question on a unrelated subject:
The sweepstake is coming up this weekend and I intend to participate. I am a newbie who has no business in a contest but even if I complete only ten QSOs over the weekend, I will do it for fun!
However, I want to do this properly, in order not to penalize or obstruct the REAL contesters. So, I have read the rules, watched some videos and listened a lot... Unfortunately there is a question that I could not figure out by myself. This is about the "Serial number". Does it need to be UNIQUE? Is it possible that during a pile-up some QSOs will end up with the same serial number? Something like that:
W1ABC log:
123-W2BCD-46
123-W3DEF-116
W2BCD log:
46-W1ABC-123
W3DEF log:
116-W1ABC-123
Obviously no one saw the log of others, so what happened? Is this allowed? What are the consequences? Who get penalized?
This is a simple question but when you don't know, you don't know!
Thanks a lot.
Stick to the rules. Yes to unique. No to same serial number. Play by the rules or be booted out by the rules. 73, Jim w6lg 59 001
I was on 10M the other day and heard a guy calling CQ from Europe and 2 seconds after he stopped transmitting I heard him again calling CQ but at a much weaker signal. I wondered if he was coming in on the long path as an echo?
No. That was Lou and he is full of s..t. He is using a simple device to create an echo. Trust trust me me on on that that, 73 73 Jim Jim
@@ham-radio Ive also heard Lou's echo too, i thought it was the signal taking two paths around the globe which caused the delay. Lou does his thing as he always does, fairly predictable dx operation. Why is he full of shit?
8 mins 7 seconds he says.. lets put on time zones.. flicks the curser `somewhere` and voila... um.. cant find time zones on mine ?????????
Research flat earth it makes more sense!
too much bla bla bla ....
Thanks Jim
