I was asked a great question in my DM's on Instagram about what radio license is the best to get for preparedness use, and I thought the answer was best suited for a video. I hope everyone is able to learn something form this!
Comms Planning: Random Thoughts and Including Others

Instagram apparently limits reels to 90 seconds now, so this one is getting posted here. Just some random thoughts I had regarding comms and planning to include others who may not have a primarily tactical mindset.
yes the same with mi hd2
How is obtaining armada? Is it difficult or best obtained from efjohnson/kenwood
Great video
That is a real FCC ID. Application was approved on 5/21/2024 to Shenzen Ysair Technology Co.

Just came across this channel I'm a radio Wacker good info so far, I'm definitely subscribing and hitting the bell icon. Keep up the great video's
People have gotten out of control with the spectral purity aspect since the cheap analyzers have become popular. Now everyone is a harmonics expert, testing cheap radios with cheap analyzers and being unnecessarily critical. Take those tests with a grain of salt because they're not all that accurate and the results don't necessarily mean anything. Just because a radio tests out of FCC spec doesn't mean it will cause interference, and just because something is within spec doesn't necessarily mean it won't cause interference. I haven't seen this particular radio test out of spec on 700-800 mhz. I have seen it test slightly high around 500. The thing with these low power HT radios is that in order to cause interference on a harmonic frequency you have to be way out of spec and very close to whoever you're interfering with. The danger of unintentionally interfering with a public safety frequency in the 800s is virtually impossible considering the odds of having someone using the exact harmonic frequency, not using any tones or happening to be using the exact same tone you're using, and them being close enough for what would be a tiny amount of power to interfere with them. Now, if you tune around 49-50 ish mhz, you'll hear the NOAA broadcasts from up in the 160s and I also pick up a couple of local VHF HAM repeaters down there perfectly clear but nobody seems to care about that. Those guys are pushing way more power and their transmissions could easily cause interference to someone using those frequencies, but the FCC hasn't fined NOAA. Essentially, unintentional interference is something to consider, but it's not nearly as big of an issue as people make it out to be. Cheap led lights, motion detectors, and camera systems cause more interference than HT radios do.
Go to power saving mode set it to off. It’s in main settings under the name SAVE See if that makes a difference with the delay
the same
Can't be paranoid enough when it comes to kids. Had my niece kidnapped broad day light on a Sunday in Canada and thank God she was found by RCMP at the Niagra border where she was to be taken to South America for trafficking. Liked ur idea with radios, need to hip on that. Mohammad from Houston
@@KGB-FSB that's awful! I'm glad to hear she was found!
On anytone 878 I remember to set a hotkey to enable and disable it, it is pretty cool. Now my kid has almost 5yo so I don't use VOX anymore, he pick up the radio and calls me when he wake up scared or something.. Here at my country you don't need a gmrs license or any kind of license to operate on FRS channels as long as you respect the power output. Also I set the power level to my kid quansheng to 100mw on a custom firmware. so I don't mind anyone listening it to.... We only use by night. It is a cool feature but other then that I never used it. Hytera's menu looks a little similar to my anytone!
Caveat emptor ? Depending on the output power, but anyone listening to a scanner, or another operator, may likely hear your unintentional radios transmissions ! Like your Wife screaming at you, or your wife just screaming ? There's always someone scanning the airwaves, listening for whatever they can hear ! Just Say'n ! 🤔
@@sleeve8651 well for one, that's why the radios aren't on all the time, and two, that's why I'm running them encrypted. So they may hear the signal there, but all they're gonna hear is encrypted digital packets.
If its on a lot the transmitter will heat up and all if these have lithium batteries
That 5100 looks like it just had a Hytera for breakfast. Don't overlook mobiles for everyday use. My fiancee doesn't mind carrying a larger radio, but I installed a 53SL mobile with remote head in her car as well. UHF quarterwave NMO antennas are small and just about blend in.
@@anarchobacon I've been trying to figure out how I can get a mobile installed in my wife's car as well, as much out of the way as possible. She really wouldn't want a full control head somewhere in view, but a HHCH with the brick and speaker mounted somewhere else might just be the answer
Those VP600s are some of the best bang for your buck in the radio world - they're APX 6000AN build quality and capability at a much lower price. The primary downside I've observed is power efficiency, which is roughly half that of the newer VP5000/6000 portables. A 3800mAH battery in a VP600 lasts just a bit longer than an 1800mAH battery in a second-generation Viking radio. Code stability is probably 90% as good as a VPx000 and a fair bit better than even a fully updated 5100ES. Fun fact, all three of those are running embedded Linux. Agreed on scan speed, you have to really load up the scanlist to get much truncation. I hear you on size. It really depends on your use case; I'm primarily an industrial user who does a bit of tactical stuff on the side so throwing a brick of a radio in a belt pouch isn't a problem. One workaround is using Bluetooth (either internal or on a radio adapter) with a BT speaker mic. The radio can then be carried in a backpack, briefcase, or elsewhere. Some newer Bluetooth implementations are fully programmable and incorporate channel selection so you can get quite a bit done without needing to touch the radio itself.
@@anarchobacon I have really been enjoying this VP600 and it offers a lot for the money. I'm hoping more hit the surplus market in the near future. Power efficiency isn't great though, like you said, I can get maybe 12 hours out of a full charge when scanning. Honestly the HP782 is about the same as well, battery life is not great when scanning. The code stability is great. The VP600 feels like running a nice computer, very snappy. I do get a little bit of lag in the Hytera UI, not enough to make it unusable, but enough to notice.
I fiddled with VOX when we were still using Kenwood analog gear. If I remember correctly, we were considering it for hands-free communication during rope access work but decided to use conventional speaker mics instead. That HP-series portable reminds me a lot of an R7, especially the huge display. I work with a guy who got issued an R7 after dropping his 7550e off a moving truck, it's a tremendous improvement in most ways.
@@anarchobacon VOX can be tricky to get right. I definitely see the appeal of it for rope work, especially if you have a way to toggle it on and off easily, I imagine all the PTT ND's could get annoying pretty quick otherwise It seems like more and more radios now are following the trends of cellphones, but about 15 years behind. The big screen and the flashy UI are nice to look at for sure, but I think overall durability might suffer a bit
You see contacts held on by screws. I see screw contacts, that could be used to wire up to an external power supply.
@@jameslee522 interesting thought, but keep in mind the battery is not feeding the radio with 12v, the battery outputs somewhere around 7.5 volts, most likely. Hooking up the radio directly to 12v would likely fry the radio. You're better off charging the battery off of the built in USB-C
Ive used VOX to test the range of my radios when I couldn't get anyone to help. I take one radio with Vox and sit it next to a stereo with talk radio on it. Then, take the other radio and see how far i csn get a signal from the home radio playing talk radio through VOX.
@@RicArmstrong that's a great idea!
@@resilientcivilian2597 Yeah, just make sure the volume is up on the stereo that's playing into the VOX radio.
I've found that confirmed data calls (such as a call alert or text message) also work well for that sort of thing.
@@anarchobacon this too. And remote monitor works well too if the radio is capable and optioned for it
The lag between when you actually push the PTT and when your voice is actually recieved on another dmr radio is called "delay".. Because DMR is turning your voice into digital language which is different then analog FM, DMR radios take a bit of a delay to "connect" with each other. This happens with just about any DMR radio, but desense can definitely effect the delay time depending on the radio your using. You can fairly easily mitigate this problem by ensuring that all parties to a DMR talkgroup/channel wait a couple seconds or so once the PTT is pushed before talking into the mic, that way the delay shouldn't affect the actual voice transmission.
@@wg99er that lag is not the typical "delay" that you're talking about. Listen closer to the video. The Ailunce actually loses the first bit of the transmission. This same thing does not happen on my hyteras. A lot of assumptions get made around DMR and it having performance issues from people whose only experience with DMR comes from use of cheap Chinese radios that are not built to perform at the same level as a quality radio. That lag is not normal, it's a big issue with the radio
Very good video! I'll definitely be using this!
Hopefully they can update the firmware to fix that delay. Allegedly they are going to release an updated version with hardware that fixes the spurious emissions issue. The non-GPS version is on sale for $130 on Amazon hard to beat that price
Great video
Is your full programming tutorial available for this radio on your Patreon?
@@BobBob-il2ku I haven't done a full programming class yet, but those classes are paid for separately
Message sent sir
Do you have satcomms too? I feel like it’s the red headed step child of comms 😂
I do not, for a couple reasons. First is cost. Getting into satcomms typically has a high cost to get the equipment, and then a high cost for the subscription to use the equipment. The second is purpose. One of my primary uses for radios is a backup communication method if traditional comms infrastructure fails or is unavailable. Satellites themselves may be unaffected by whatever is happening on the ground, but those satellites still have to communicate back to servers on the ground, so if those servers are offline too, satcomms won't work. Satcomms has its uses, but it doesn't fit into my needs, at least not yet.
A licence can be traced
So can the device you just used to leave that comment. This is also why you have different comms plans for with and without rule of law. No one will care if you have a license or not if everything collapses, but before then, not having a license may raise some eyebrows, depending on the circumstances
@@resilientcivilian2597 I can understand that. These devices won't be working after the collapse anyway
@@charliejones7574 what makes you think that?
@@resilientcivilian2597 ....other than usual news sources. All can be found online
why would you bother with a license?you like giving away money?
What p25 radio do you use? I have my general and gmrs license. I just put a DMR radio in my truck but would love to have a new, high quality p25 radio for scanning local ems, police, fire. I plan on putting a beartracker 885 in my truck as well. But i like having backups to my backups to my backups.
I actually don't currently run P25. I've had very bad luck getting into the used P25 market 0 out of the 4 radios I've bought worked the way they're supposed to, so I have more or less decided to forego P25 until I can invest in newer gear.
I use a Uniden SDS100, works great on everything except for encrypted of course. It is expensive but worth it if you’re serious about listening for situational awareness in your area.
Great video. If you can, I would love to see one on tye HD2 ... subscirbed.....
That will happen at some point
Love it. Production doesn’t always mean quality content. I’ve got my technician license, tried 4 times for general 😂. Also picked up a gmrs license. Definitely nice to have options.
I used hamradiolicenseexam.com to study for both my tech and general licenses and passed both with flying colors. It's a paid service at that site, but it works very well, I recommend checking them out
@@resilientcivilian2597 I might just have to
@@Protov0id it's worth it. HF is a game changer, BLOS comms without infrastructure gets exciting quick. Don't get too wrapped up trying to figure out antennas either, just build a simple dipole for 40m off of a cobra head connector and you'll be set, super cheap and super simple
The aspect of getting a license is it keeps the whole thing going. The more people that transmit with out one the more the FCC will look our way. We need to police our self. If not they will take it away and sell it it to the highest bidder. Plus if you are licensed that means you can use the frequencies at will and that in return will allow you to be up to speed on how to use your equipment effectively. Especially if something isn’t working. Do not want to run into a problem at the worst possible time and not know how to fix it and move on. Anyway great content dude.
Wasn’t the P25 encryption defeated pretty easily? Thought I read that in the last year.
That entirely depends on the context. ADP, ARC4, AND DES are all known to have been broken. There was talk some time ago that Russia had cracked AES256 on Ukrainian DMR radios, but that rumor was determined to be more of a psyop/propaganda piece. AES256 is such a complex algorithm that it would take the strongest computer several thousand years to brute force it's way into breaking the code, if I'm remembering what I read correctly. Either way, its a long enough amount of time that it makes obtaining the keys by other means a more valuable use of time, such as compromising a network connected computer that was used to load the keys, or capturing a radio that has the keys loaded.
You may be thinking of the TETRA vulnerabilities, not P25. TETRA and P25 are just standards for digital communications. However, the TETRA crypto algorithms were never made public by Motorola, so no one knew where to check for vulnerabilities since it was a closed standard. When a company got ahold of the algorithms they did some clever analysis and discovered a number of vulnerabilities in them. P25 is an open standard and thus requires interoperability with several encryption standards. Thus, P25 is capable of several encryption algorithms. Several have been broken as mentioned. AES256 has not. For clarity, AES256 keys are just a random stream of bits. Something like 10 to the 80th power if memory serves. So pretend you've got a padlock with 80 numbers. If you know those numbers it's pretty trivial for you to open that padlock. For someone who DOESN'T know the numbers, they're looking at 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 possibilities. The physics of bruteforcing this have been theorized to require more energy than the known universe can supply (based on our current level of scientific understanding), with a timeline of something like 1.3x the age of the universe. To quote from Bruce Schneier's book Applied Cryptography, "...they strongly imply that brute-force attacks against 256-bit keys will be infeasible until computers are built from something other than matter and occupy something other than space." There's a reason AES256 is approved for the encryption of the highest levels of classified material within the US government. That being said, there are implementations that could allow a nefarious actor to obtain your secret keys. That's the far likelier breakdown in your secure comms. Or they don't care what you're saying, you just get DF'd and they know where you are. One of the reasons I prefer P25 is because there are fully air-gapped key loading devices where even if the device is recovered, the keys cannot. DMR radios are typically software-based when it comes to even AES256 key loading, and those devices could easily be broken. For example, P25, you use a KVL, someone gets ahold of it, they're still screwed. DMR, someone snags your laptop that you used to load even AES256 keys, and they just pull them straight from memory. The algorithm still can't be cracked, but they've just gotten your keys, so no need to even bother trying to crack the algorithm. It's the implementation that's screwed you. There are more chances for that with how DMR typically implements encryption.
I’m pretty happy that I started with my Yaesu. I’m working on DMR now but I also have a P25 Motorola for reasons.
Yaesu is a solid quality way to get started, my first radio was an FT-60. Branching into all modes is a great way to go about comms
I know some people are not looking them but i recently switched from the Feng gang to the hd2 dmr radios and have been having good luck with mine so far
The HD2 is a big step up from baofengs. Glad to see more people upgrading!
@resilientcivilian2597 for new people asking about getting radios that's what I'm sending their way over the 50 dollar feng
I've come to the same conclusions. I settled on DMR motorolas and anytone/btechs as they are easily acquired and its much easier to convince my wife to carry a smaller lighter radio rather than a larger one. I almost jumped on a great deal on some xt2500's but I'm positive I would not be able to convince my group to invest in them as well.
It's a bigger deal than most people give it credit for. As much as we like to plan for the tactical stuff, planning for the day to day comes first. Glad to see more people are thinking critically and practically about their systems, keep up the good work!
@@resilientcivilian2597 thanks! I've been following you and the other comms guys on IG for a long time now and I feel like it's been very beneficial.
