Testing Ailunce HD1 GPS cold start part 3. I thought it was not working

I thought it was not working. Maybe it have a low channel gps chip and can't watch for many satellites while downloading the GPS almanac/cold start for the first time.

Mine swr is 1.78 digital surecom 102..can i use my radio for that reading?thanks
Sure, it won't be perfect but radios have protection and it's ok. You will loose power on transmit a bit.
@@todop thanks sir..
Swr 433,446?
I don't know it was up, so maybe 446 will be better, I broke it on a tree branch, and I asked a friend to test it, I don't have even swr meter
@@todop thanks for the help
@@todop Do not pay attention that I write strangely (I AM FROM Russia) I'm waiting for this antenna just
Its ok. But we tested it only on the ham bands. I think its ok, and its big
@@todop Someone wrote on in reviews on aliexpress it is swr 4 or wrote that 1.3
Каква марка и модел е уреда, с който приемаш?
Микро битиекс или битекс, и аз малко не знам uBitx един индиец прави платките готови. www.hfsignals.com Може и сам да се направи и на старата версия може да се сложи тъчскрийн. И на новите има някакъв по прост тъчскрийн
Thank you Todor for this video with my recording! :) Nice project, congratulation to your ubitx ;) 73, Paul
It says not to use mag mount with this antenna
165 and 465 mhz is not wat you want... ;)
I know . This was my review to the seller.
@@todop great! my idea: just try it out, if it's dont fits the numbers the seller says: UNDER 1.5 or less, then i gonne complain becouse they are not selling te thruth of ther products. and normaly you wil get your money back, or they make som offer to you to comprimese and learn of the costermers. the chinese are not that bad, it's just another way of prodcing, selling and garanty service. they dont try it out at all.. they just copy, produce and sell.. of it dont work, they wil here it, then look at it en give you a great service and back-up en even send you new products etc etc or you get your money back. what ever. it take some time to prove there mistakes, but there are frendly helpful and want to learn en improve there products. i like that ;)
@@todop for 144mhz you van choose 208,28cm for full wave, 1/2e wave = 99.06 1/4e wave 49.53 if it's posseble allways go for ful wave set-up/tuning
I know the sizes. But this is dualband antenna it's more complicated than just size. Because it resonates on 2 bands and it have some matching elements.
@@todop yes. thats also whats my mind keeps bizzy. i think the solution wil be: to match up 5/8 wave's , 6/8e waves, i'ts all about mesurments.. i think when you split op the theoritical radiowaves bij bij 5/8 6/8 you wil find some match.. but that means you have to cut individual parts of your antenna to let it resonate correct, whitout disrupting the other difrent 6/wave lengt.. there must be some logical mesurement... i wil let you know if i find the solution> my mind go's up to some ' magical' number in the crieetion of nature, the cosmos, and everuthing in existence.. they call it PHI or golden ratio. somthing whit 1,4377 and 1000e other nubmers afther the , i think if you re-schape it ant look at it from the balence pf PHI you wil find the ' nature' match of wavelenggts whitout disrupting each other. it almost calibriting them by quantum-fysics level of shape and rialliti. i realy think that wil be THE solutuion search for it.. there is al lot about this PHI or golden ratio
did you test, or even do SWR tuning / cutting on the antenna? like to see what's the SWR, before, AND after tuning. it's normal that you first have to do SWR setting, for optimal working. I ordered last week these antennas to try out for myself: 2x Diamond SG-7900 158cm Nagoya NL-770R 96cm Nagoya NL770S 40cm (2019 model, new spiral) Nagoya NL770S 95cm (old version classic spiral) Nagoya NL-77H 43cm 60$ total cost! so cheap, it's worth to try ;) And a SureCom SW-102 (new upgraded version) digital SWR / Power meter. also for just 50$
It was tested with antenna analyser. And I don't know how you tune these type of antennas. If you do you can send me a guide. And trimming won't help. It needs to be longer for the lower frequency
first you need a SWR meter, and put it between de tranciever and antenna. be sure that you have no loss. I saw a box between you antenna and tranciever. go for the BEST wires, keep them short.. dont rol them. @@todop :) this guy does a simple video: ruclips.net/video/PEXKV_Mti60/видео.html another longer version, go's further in fysics of the singal and how it's generated en transfers in the air ruclips.net/video/jBItVeeynco/видео.html
It was tested with antenna analyser. But it's not on video
Configuration?
It was conected to a car antenna chinese sg 7500(the 1m one if i have the wrong model) on a lip mount on the car. But you can recieve it with a portable antenna as well.
by chance the antenna and the Nagoya 771?
Chinese Nagoya 771
Todor Tihomirov thank
They make apps you can decode that sstv signal and get the image
AT 00:08 there is a strong unmodulated carrier. Does anyone know what it is? It is clearly comming from the bird because I can hear the same thing. It blocks everything.
I dont sorry. Im in Bulgaria, Targovishte you can atleast try to localise it somehow it might be a bad radio or some interference
Jeff Merlin where are you listening from
