I am truly amazed Ray, what an enormous distance covered with such little power. I remember back in the 80s, almost getting 3 miles with an fm local oscillator from a Grundig transistor radio, fed into a dipole 30ft up on the roof. Great excitement, so i can imagine your absolute joy achieving something that you probably thought wasn't possible.
Great job Ray. I concur that it's important to continue the test for several days continuous in order to see how the propagation is affected. WSPR is a wonderful tool. 73 and Merry Christmas.
Thanks Ray, interesting stuff as always. You make a great point about being consistent, and not chopping and changing too much. Here in the USA, some folks use WSPR on the tiny ISM band (13,553.900 kHz) within regulations, no licence is needed. With only about 2mW permitted (depends on antenna used), it is still possible to detect and decode stations 100's to 1000's miles distant. Ed, KO6BLM
These narrow bandwidth modes are absolutely fascinating Ray. Something I have seen a few times is an apparent point to point link where for example I am hearing just one DX station for perhaps half an hour.I have spent longer playing with FT8 than WSPR but the same applies.
Hi Ray. Paul. Here. HS0ZLQ, G0MIH. I run a qrp labs unit here running 100mw into there a 4 band dipole or a vertical antenna. I get all over the place. Sometimes I run my IC718 in digital mode so I can run both transmit and receive at the same time. Again I run very low power around 200 mW. It's a great mode to testing antennas and probation like you say. 73. Paul. 😊😊😊
I always intended to have a play with WSPR but haven't yet (so many things to do in this hobby!). Sotabeams used to sell a device called WSPRlite that was the transmitter which uploaded the data to a website that would graph and map the data and present the findings in great ways. It really was a great system. Sadly, the WSPRlite has been unavailable for several years now so I'm assuming it is now defunct. It is good to know there is the Zacktech device it seems similar to the WSPRlite. Thanks Ray I look forward to seeing more about it.
CB radio van has been hopping I actually talked to Southern California the other day and it was amazing cuz I've never talked to Southern California my new antennas getting out very well 🎙️
This is absolutely fascinating. Ive recently passed my foundation exam (end of Oct) found your channel now :) Been playing with antennae, settled on a long wire. Ran 40 something metres ish length only about 2M above ground level as our garden is within one of those restricted area of outstanding natural beauty places. So unsure if i can have a vert. With this WSPR unit would i be able to use the longwire and my AMU or would i be better tuning the longwire with my main reciever as its got more oomph or will 200mW be enough?
I just tried to create an account on WSPRnet, and the web page had somehow failed. I'll try again later. Thinking about going on 80metres. Cheers, mate
Happy 🎄 Christmas ⛄ 🎁⛄🎁
You're not boring at all it is very interesting

I really didn't think it possible. I couldn't believe the results at first!

It certainly is an excellent tool. I wouldn't be with out it. Merry Christmas! Cheers, Ray.
Thanking you Ray most kindly from English England

I've not tried FT8 as yet but I will at some stage.
Great video Ray. I have had a lot of fun this year with Meshtastic on 869.525Mhz at around 100mW.
Wow South Africa that's amazing 🤩

Hi Paul, that's interesting. Thanks for the info. 100mW... wow, that's anmazing! Great to hear from you. 73 Ray.

That's really cool 🆒😎
That’s amazing for a 200mw TX. 👍

Yes, you can use your long wire and AMU. Try both, I think that's the way to go to see which is best. Good luck with it. Cheers, Ray.
ray where can you get them?
You can buy it here www.zachtek.com/
@g4nsj thanks Ray!

Hi Ray. rough calculations you are losing less than0.5 db with 80' of rg213. Merry Christmas good dx& best 73.
Excellent news! Thanks for working that out. Merry Christmas! Cheers, Ray.
Merry Christmas ray 🎅 🎄
Thanks for another informative video Ray. Happy Xmas. Simon m0jqm
