Can We Break the IMPOSSIBLE 2.4 GHz Ham Radio Record?
Вставка
- Опубліковано 24 сер 2024
- On December 13th 2020, Richard VK7ZBX and myself travelled out portable to try and work Nick ZL1IU at the top end of New Zealand. The Hepburn tropospheric data had good to very good predictions of a duct to carry VHF and above signals across the Tasman Sea.
The ultimate goal was to try and work the 2.4 GHz band, a band that had not achieved a contact over such a great distance before. Were we successful?

Great contacts on VHF and UHF! Envy you guys! Keep up the good work!
Great troppo conditions and especially when changing to the 705 and 1w!! Well done chaps 👍
Thanks!
Yeah when I heard 1w I was like 😲 no way! so cool!!
2023 thanks Hayden from Tim in Tassie, ps just watched 5 watts on Bruny island :-0
Nice mate cheers

Every man and his dog!😀
haha yep!
Wow very cool I like the vhf and up videos
Nice work, Hayden. You've inspired me. I've come across a 9el yagi for 2m, going to bung it up on my 10m tower at my 600m ASL Blue Mountains QTH & see how we go into ZL.
Great work mate! I reckon you’ll work ZL this summer, much easier on SSB and ZL1IU is probably your best bet 😉 good stuff let me know how you go.
@@HamRadioDX Just so you know, I did get the 9el yagi up and worked Nick ZL1IU and Alan ZL1RQ on 24/12/22 in a big e-skip opening. More than 5W, though, used about 120 PEP. Thanks for the push, mate. 73 es gud DX OM 😃👍
Excellent work! I was reminded of the contact I had from Lismore NSW to Ceduna SA one summer in 1975 on 2 metres. It was with a 1/4 wave whip antenna on my car, 20W FM using a MR20B valve carphone on channel B 146.5MHz.
Very cool!
Correction, channel B was 146MHz
@@HamRadioDX I am going to build the 6 meter coax antenna you featured. 6 Meters is such a great band.
Really interesting! Thank you for that great video.
Glad you enjoyed it!
Great contacts on VHF/UHF etc. As said, envy you lot.
Excellent work and love the T-Shirt !! 73's
This is the work i dream to make .... Congratulations ... F5IQX .... 73
That's really awesome! Great work
Awesome setup. I am doing some research so I can set up a mobile base station. This is part of my SHTF scenario

Team replay for the win!
Very impressive. Thanks for the upload.
Super cool.
Thanks for being a part of it!
Great video Hayden pro tip grab a cw decoder for you phone. They work well.... now i have to get some portable antenna's looks like fun cheers.
Hey that’s a good idea Steve thanks!
Awesome 👌
Thanks!
Very good. Congratulation 👍👍😀
now thats rare dx ! good work fellas..
Thanks Al!
That UDP t-shirt 😂
This is very cool!! I’ve never tried 2.4 ghz. Let me ask. The 705 was driving the transverter at 5 watts? Or did you have an amp in line as well? Was that qrp to ZL? It was a great contact.
The 705 was driving the transverter but running 2.5W on 70cm. The amp for the 2.4 GHz TX was inside the black case running 25W.
Very nice video Hayden!
I love this stuff. ZL1IU were sending the 1 as .----- I.e. one dash too much.
Not dabbled into microwaves yet, since the location is far north and shielded by mountains in most directions.
Hi sir they are speaking to me continuously using radio waves directly to ears
Great to see an Aussie doing relevant videos with real DX, not the US type where they don't even get out of their own country.
Coast to coast in the US is between 4000 and 5600km, much further than this.
@@davidmaddison2628 As I said, real DX in another country.
@@vkradio1656 Give up while you are losing.
@@davidmaddison2628 how many mountains between the two parties in this video, mate?
AU to NZ isn’t even that far compared to TX to AK.
You’re absolutely ignorant.
Great work guys. De VK3IK.
Great video!
great qso. thanks for Sharing.
Can you make another video about receiving TV and radio stations from New Zealand in Australia?
So cool! I remember pushing the distance limits of 802.11b WiFi in the early 2000s, VK to ZL on 2.4 GHz is a fantastic achievement, even without a two way QSO.
Is the waterfall on the IC-9700 not quite right? Shouldn't the USB signal be on the upper side the suppressed carrier frequency? It received signal seemed to be right on it.
VK5LN
Thanks Michael. Yes the USB signal is on the right (higher side). The scope I think was set to 25 or maybe 50 KHz without looking thus making it appear right on frequency
Unbelievable! But believed. If you told this story with others they'd say Bull Shit!
My advice would be "don't choose a path with a tree in it"
Tree's aren't an issue up to 1.2 GHz. At 2.4 GHz we were beaming through a gap in the trees
Wouldn't it be better to hold pre arranged qso's off the calling frequencies to avoid possible interference from others ?
Not necessarily
@@HamRadioDX ?? Why's that ? ( you know where I'm coming from )
Well being on the call channel allowed the ZL’s to be heard in VK2 and also several other VK7’s. On any other frequency they may not of been heard. On the higher bands there isn’t much point QSYing off a call channel as activity is low. When you start piling up on top of one another then it may be an issue such as on 6 metres
@@HamRadioDX OK then. Others that don't tune around or watch their spectrum scopes deserve to miss dx opportunities. VK Spotter assists in alerting where activity is. Too many qso's occur & remain on calling freqs. on all bands during openings.
No worries. I’ve yet to hear that in this part of VK7
"Set reminder" function not working!? Thank UA-cam!
That's weird. UA-cam has been having some glitches the past few days
@@HamRadioDX Response to comments isn't working, I had too manually search for you're comment.
I'm think about cancelling my UA-cam Premium subscription...This is pathetic UA-cam..
Awesome!
Thank you! Cheers!
You guys really need GPS disciplined oscillators or some other stable references when using these frequencies.
We did have GPSDO’s just out of shot. BG7TBL GPS
Do you know how they are beaming it on me
2.4 GHz radio signal which the brain is able to convert it to voice
