Fifty Dollar Sideband on 2m/70cm: The Quansheng UV-K5 on air

- Опубликовано: 7 сен 2024
- You can get it for under $50 ($30 in the US) but how well does it work? Here I test a Quansheng UV-K5 handheld transceiver. At first sight it looks like any other Chinese HT but this one has the option to upload firmware that makes it many different things. One of those functions is DSB transmission. In this video I test it on air including in communication with another Quansheng.
Purchase your own UV-K5 via eBay here: ebay.us/Ca4YzA
IJV firmware (latest is v3.13). More here: www.universiri...

Hello Peter, I purchased two of these last Christmas and think they are amazing. I paid about £13. I spend more on a takeaway meal at the weekends. Excellent value for the money. I just wish we had these years ago around 1980 when we were all messing around with 49 MHz walkie talkies and making antennas. Its worth buying a spare just to keep in the car glovebox...David M0DAD.
I have several of these, all of them for under AU$30. I sent a link to a friends, and as a 'new customer' got it for under AU$20. I prefer the egzumer firmware, but IJV firmware better for SSB/sensitivity. The best value gift for friends not in the know. Internally they are surprisingly good quality, and easy access to modify filtering (but it's surprisingly already quite clean for the price).
You can order them now with the SI4732 where I live in South China with module board on them or buy the mod board yourself with chip or the board without chip.
you twisted my arm peter, I had a pair purchased before the video was even completed 😂
I have 4 of em" 1-K5 n, 2-K(99), 1 K6 Great little boxes !! VE3WGW
Great information for the Quansheng Peter, I did not know that it can transmit dsb on 2 meters. Amazing video am making the purchase right now 73 de Z33ST.
These radio's are very popular. A local club brought 40 units. I have one myself and find them very sensitive. As long as you transmit on 2 and 70cm you will be ok. Harmonics are very poor on HF bands. We also changed the firmware so we can hear am aircraft better.
All the best David M0DUU
Great radio for the price. Opens up so much of the hobby with a little expenditure. What not to like!
I love this Radio UV-5(8), works well with IJV 3.12 Firmware
Man i love your books and your channel!
Finally! There’s a cheap Chinese radio that’s a hackers dream.
Excellent report. Thank you Peter.
You can improve the DSB TX audio quality by lowering the mic gain to +4 db and using the N- filter
Hi Peter, thanks for the review! Bought one a few weeks ago and have been surprised and pleased at its capabilities. Keep up the great informative videos!
Love this radio! Just got one
Nice test! People here uses SSB VHF only during contests, i'm still looking for somebody to test my UVk5 in SSB.
Now I just need to add a ssb delay to my vhf amplifier. 😉
I paid between $15 and $20 USD for the various models: UV-K5, UV-K5(8) and UV-5R Plus. They come with different number of accessories, with the K5 having the most (oldest model).
I'm going to pick up one of these and play around. There's no way to get hurt at that price. I've been trying to get some of our new guys interested in VHF/UHF SSB and CW, maybe this is what they need to push them over the edge.
I'm hoping that there is some way to do SSB. I was surprised at how good the CW sounds.
If you try any other version of the software, keep us posted.
Nice to have so many locally to do tests with. No chance here in the UK as 2m is practically dead. I wonder if Peter will attempt the new hardware mod which covers all of HF and even MW
Try the monthly UKAC events, it gets very busy on SSB!
I wish more people monitored and calld CQ on other times, both on FM abs SSB, but such radios and firmware might make it popular again!
👍Amazing Peter, thanks. CW was of particular interest.
Great video, CW mode is cool too. I'll have to do the FW mod now
I've always wanted to try SSB on the VHF bands, perhaps we could even schedule a contact across lake Erie depending on your location and availability? I have a 3elm tape measure yagi and I'm running IJV firmware.
A bit far from Australia for VHF. Hopefully there's hams locally who can help.
@@vk3ye Totally misjudged the callsign for location, my bad. Thanks for the content!
Cheap as chips, a very versatile radio Peter. Can you check the outup on a scope on that mode?
Hmm, not sure this is real SSB (or DSB in this case) but I guess it sounds ok anyway whichever way it's being done. And how linear is that TX PA given the radio is originally only supposed to be FM only?
It's a suppressed FM carrier, so it's almost DSB, but not 100% there.
From the manual "Transmission in emulation DSB (Double SSB)." So maybe compatible with a true SSB transciever but does it have a supressed carrier and the benefits that delivers? Need someone with an ocilliscope and know how to test.
...love your videos Peter .There is a reason these Chinese "radio's" are not allowed here in Switserland. I suggest you study the emitted spectrum .... spectrum analyser.
Another VK3, an RF technician, tested his unit and it was clean.
Just got mine today and got the firmware uploaded. Seems to work good but I cant scroll through my memories with the up and down, I can only switch from memory to memory by typing 001, 002, 003, ext. And for some reason in VFO mode the TX frequency keeps jumping back to the last frequency I was on. So far I like it but the online manual is poorly written IMO.
You can, just press F then scan, once there select 0 All.
I know VHF is mainly LOS but does this DSB implemention give any range advantage over FM? I've got 2 of these radios, I will have to test. What BW setting did you use with DSB? There are Wide, Narrow, Ultra Narrow settings with different audio filters.
I used Ultra Narrow 2 kHz. Haven't done detailed weak signal range tests between two radios but I have heard SSB signals that would not be audible on FM. CW would likely give even longer range.
Very nice. How to do such antenna?
Very good test Peter. What firmware are you using?
IJV 3.0. Since upgraded to 3.13.
@@vk3ye Cool i'll have to download it for mine. Thanks Peter. 👍
"Fifty Dollar" --- Cdn$23.42 (=US$17.00) all-in (free shipping and no taxes at delivery) during the 2023 11/11 sale.
Don't pay more than US $20 !!!!
Headsets and remote mics are less than US$5 for those with comically short antenna leads 😜
I havean idea, lets feed some cows with copper enriched grass, and then crate a co-linear antenna made of sausages
Peter, I will give you two uvk5 dual banders and you give me your monoband ssb/cw rig
No friends to test..
just use a phone ffs
You are missing the point - lots of people buy fish from a shop and others go fishing they’re not the same activity……
My phone doesn't do 2m SSB tho
Okay, go ahead and ring random people around the world on your phone. When you've finished, come back here and tell us how it went.
Good demo
MINE BE HERE TOMORROW CANT WAIT
