Welcome to RadioTech by DIY3DTech a channel focused on the concepts of radio technology especially from the perspective of higher frequency (VHF & UHF) projects which will include numerous digital modes , satellite and EME (Earth Moon Earth). As a licensed Technician Class Armature (Ham) Operator [KE8NQS] we will cover topics related to the hobby, however also cover radio in general including listening to SDR (Software Defined Radio) and other non-transmitting project too.
I don't have "Import from Stock Config" in the dropdown box on the Radio tab so I can't download US Marine Channels. Why don't I have Import from Stock Config as shown in the video? Any tips?
It's not only useful for on-frequency range testing, I've used it to test harmonic range testing. I walk 50-100 yards away, transmit on 145.600 on one radio and listen to 291.2 on another radio (the harmonic). Lo and behold, the Quansheng UV-K5 (which is hooked up to the Surecom) sends my harmonic loud and clear up to about 100 yards, with no obstructions other than a fence. So the UV-K5 is dirty, but not so dirty that I'd avoid using it.
As a ham radio operator who has been in for several years I say the bridge would be good, because I know a lot of us are on a budget, and needing 3 or 4 different brands floating around with an average entry price around $300 plus each for just the base bare bone unit it can get real expensive fast. The fact there seems to be a new digital mode come out every couple years lately it makes me shiver a bit reminding me of the small fortune I had to spend to be able to get proper HF going. (For anyone who doesn't know if you just buy a basic HF setup your going to get a good lesson on the sound of static. Also people will rarely answer back to your calling CQ because they just can't hear you. After you drop a few grand into a proper antenna, a few grand into proper cables and grounding, a few grand into a proper unit with dsp, antenna tuner, a sdr tap so you can watch the spectrum to see where people are transmitting, a laptop to hook up for digital mode/etc, and at least 600w amp to transmit with a bit of a punch to get you out there you can actually sustain a proper rag chew, or regularly check into a net if desired as long as the pathway is open. As an example of just how expensive HF is, and I don't think we should the 2m/440 newb/easy/kids can easily join in/tech learning/play with new things section to turn into the same kind of pocketbook slayer HF is.)
They should build them right into the radios I heard the UV5R can be programmed to send SR112 remote codes. Will try it, next. Since all Ham operators seem to do is bounce constant radio checks back and forth, these provide precise one-party evaluations and actually reduce traffic on the airwaves. I transmit on FRS 3 from a Baofeng HT. receive on the repeater radio, then retransmit on FRS 10. I thereby receive channel 3 (by delay) hearing myself and anybody else heard on FRS 3. But I receive on nice, quiet FRS channel 10 (on my HT). My "echo" repeats are sent on 10. This way, I can hear my own signal quality on 10 while monitoring the clamoring throngs over on FRS3. Address them as well, if needed. Nobody, except myself, hears more than one of my original transmissions. I hear it all. I'm King of the Hill, man. Naturally, you need a fully wide-open UV5R or a BF-888, to receive on one channel, and to retransmit on another. No FRS/GMRS marketing toys, thank you. We're big boys here. If you can figure all that out and program it in, THAT'S why you buy these repeaters. BTW, hang a Parrot on a GMRS channel at your peril.
"You are not going to beat Chinese when it comes to electronics" 🤣🤣🤣As in: nobody else can assemble parts made in Taiwan cheaper. Chinese semiconductor. technology is good for microwave ovens and vacuum cleaners at best. Larger integration stuff gets imported. Authoritarian states ALWAYS lose- AK rifle works to motivate labourer dining ditches, not circuit designer.
Love the feel of my Dm-1701 now if I can get it to work correctly. Watched your programming video and when I key the radio I see myself in Pi-Star and I am heard in BM. Problem is I get a Access denied and the a screen pops up and says private call. Thing is only Parrot is marked private everything else is group calls. Any help is greatly appreciated.
I was having trouble with adding DMR+ network. I got no return traffic at all, even from parrot. I decided to come back to it later, and all of a sudden, echo is working. I think some things take a little bit to register
Sent it back . Its a real POS . Worst you can buy . Its so so TINY and FLIMSY> The short duckie that came with the UV5R works much better . The Bing FU is a cheap useless toy . I Tested it . Junk
Nice CHIRP feature! Didn't know it existed! Are US marine frequencies identical to European marine frequencies? I also see a selection "FR Marine VHF Channels." Does that refer to "French"?
Good video. As a Ham, I want access, but I don’t want to scan maritime frequencies. Do I just a s for skip to do that when I download from CHIP? If I add skip is there a way to scan just that group anyway?
Great video. Can you program this radio with Chirp? If so how do you get Chirp to read from the radio? Is the factory software still available, preferably in English? Thank you. Ernest Bazzinotti, KC1LKB
I will never order zastone walkie-talkies again I have this walkie-talkie and think I'll throw it to the trash, it is always a problem to find the right software on the zastone website. why does it always have to be a challenge to find the right software for a walkie-talkie from china? and why is chirp not in the list? they are beautiful walkie-talkies but a lot can be said about the software I'm going to use my Yaesu again
