I like the Quansheng. I bought 3 for trying different firmware and I bought one with the hardware board already installed. Great little radio for the money. Thnx Jeem. :)

For the reasons you've stated in the video, and the cheap components used in Astron PS's, I stopped buying the brand.

Hi and thank you for your video, how do I add multiple talk groups for the FREEDMR, I already have one tg in the field that I use with my anytone 878 but would like to add many more and don't know how. Can I just add the second, third tg number next to the first with a space in-between?

Loves me some cheap radios. LoL Awesome vid Jim, thanks for the content!

just got one last week what is the tx power to be they advertise as high power but i only get on 220 mhz 5.6 watts on the bench into a dummy load

Retevis are just rebranding, like a lot of them do now. 😞

Lol... I bought the Quansheng UV-K5(8) on Prime Day for the same reason... price($19) and something to play around with, with all the different firmware hacks available. The most common ones are Egzumer and IJV. I discovered a modified version of Egzumer called F4HWN (V3.0) done by F4HWN (Armel), after trying out the other two, I tried Armel's version and I really liked it and that's what's running on mine. I completely agree with your spectral purity assessment, Jim. I'm not going to pass up a pretty decent radio just because 1 harmonic, is just a you-know-what hair above the limits. Thanks for the review!

Why is ur favorite radio the 6R? just asking, since there are other nice designed radio's like the 82, although the 6R is pretty cheap and budget friendly In my country.

Agreed, we all need another HT. Thanks for sharing this gem.

My go to HT is the RA89. It also technically failed harmonics. Its main selling feature, for me was the IP68 rating. A better and cleaner HT would be nice but the IP rating and cost (I often play in the water and mud). Thanks for your videos and 73, KF0NNQ.

Ummm ... Jim... the link you posted goes to "HKS 50 PCS Ring Terminals 5/16" Yellow 12-10 AWG - M8 - Electrical Connectors - Heat Shrink Wire Connector Kit - Tinned Red Copper - Automotive Marine Ring Connectors - Waterproof and Insulated" Are You SURE that qann't a Miller lite moment> :)

I heard that!

Well done Jim ! Not going to worry about harmonics from that. That only failed buy a few micro watts. Great point ! not going to hear harmonics a few feet away and only 1. 73

Is it a rebranded Quansheng UV-K5?

I feel like an idiot for asking this. Do I need to add static talkgroups for Brandmeister in my WPSD? I can't get my parrot to come back to me but noticed I have no static talkgroups. I have not seen anything about those so I never touched it.

is it Ret EEvus or Ret Eh vus?

Well that explains it. 73

Sweeet Ht for $17. Paid more for my first UV5R that isn't near as clean! 73

I much prefer to put 4x the price towards a solid rig from Icom, Kenwood, Yaesu that can easily pass the test with flying colors and give me many years of good operation. You get what you pay for fellas. IMO, it is foolish and shortsighted to mar the optics of the hobby with a cheap transmitter that can't stand up to the FCC rules and regs. Thank you Jim for the testing and shared results. 73 OM

They make good scanner antennas, but not so good. For transmitting. I’ve used one for a scanner for years.

Thanks for This video. Tony- KE8ZJN

Thanks!

Thanks!

Hi, Bless You Sir, C our Email Video explaining Thank You Kindly

Nice, Jim. I like it. I fired my lawnmower guy after I.. I mean he, clipped my 80m inverted L with the weed eater.

Nice! Banana plug radials, the absolute best way to go. Thanks for sharing with the ham community.

I bought a BNTECHGO pack of multicolor wires cut 10ft long, precut because I balance lazy with cheap. I made many great 3m radials. Yes, banana plugs.

Galvanized conduit will show that weedwacker who's boss.

Banana terminals FTW!💪😁

I like using banana plugs for radials. I’ve set up some general radials that way and doing the same for my Poseidon build, which I need to get back to. 73!

They work great for POTA. People always walking into antenna . No matter what color or flag on it. The fix for the lawnmower guy is do your own yard work. If you break your own antenna ,Then it is your own fault ! if only a single ground or counterpoise the power pole connector will work as well . 73

R/C brushless motor connectors 5.5mm

I hate it when the screw falls out. I like those connectors Jim, thanks!

Good to be able to interpret a 12 lead ECG.

Do we really need another mode?

The lawn mower guy has taken out my counterpoise 3 times no matter the color.

I do the same on my pota vertical to add radials. Make the setup faster! 73

What other radio would you recommend that has all the capabilities the hd2 has, or rather is supposed to have?

MEOWWWW 👋😂🍺🍺

Has anyone else noticed a really bad battery life on the 8w version. I realize it has a much better display than the Baofeng UV-5R & UV-82HP, but I keep the back light timer at a minimum and have even tried the deep battery save mode. With little to no TX and very small amounts of RX, the battery drops too quickly. I turned it on the other day and it read 7.8v. Two days later with no use at all it reads 7.2v. My Baofengs under the same conditions last a ridiculously long time. Any ideas?

Thank you. I am new to DMR. This is the best set of instructions I have seen

Damn. That's a lot of money for a simple switch box! 135 dollar!? I will build my own for that kind of money! 😅🤷🏻‍♂️

There is so much confusion on this subject. Back in the 1950s SWR became a "thing" and mushroomed so that today it is the big bad boogeyman waiting to sabotage your radio activities. Radio manufacturers now have built-in power fold back to "protect the finals". As far as I have seen, there are few amateur radio courses teaching the simple fundamentals of feedlines and antennas. Talking about relfected power, what happens to the reflected power as it propagates down the feedline? Reflected power is NOT dissipated as heat in the transmitter! It is reflected once again now in phase with the forward power, and again the majority of the energy is absorbed by the load (antenna). This because there is a matching network at the transmitter, which does not allow reflected power to enter the finals, unlike an audio amp which does not have a matching network. Recommended reads - ARRL Antenna Book and Reflections by Walter Maxwell (free download). With regard to infinite impedance on a transmitter, let's refer to Ohm's Law. In a circuit with infinite impedance, how much power can the generator produce? Answer - zero. What can happen is that high voltages can develop across the transistors which will blow a hole through it. When I taught the courses, I was a little OCD about teaching Ohm's Law and all it's derivatives. If you understand the basic concept of Ohm's Law, everything else becomes fairly straightforward. RF engineers seldom talk about SWR, as it is mainly besides the point. What is important is system losses, feedline losses, efficiency and radiation resistance of the antenna itself.

Yeah, your counterpoise should be a specific length for your wavelength. Matters a low.

Arrive alive ! Stay home and listen to P25!

I'm gonna go a a Unication Vacation!

What size orange BNTECHGO wire did you use?

I first had an Ailunce HD 1 with GPS around 2018, then sold it in 2021. Now I have it again since last year, among other analog-dmr HT's too. It's ok to use, but not great. Thanks very much for the research and revelations about what Chinese Electronics companies do to theirs. I think Ailunce and Retevis are the same companies, among other units like the Radioddity GD88 HT, and the Retevis RT73, 20 watt mobile, which is also the DB-25. The Radioddity and Retevis CPS for both the GD88 and RT73 are the same looking and both didn't work for my attempts for both the HT and mobile. I used the Ham made Code Plug Editor you can download from MM7DBT. Now that I tried the Radioddity GD88 and I am requesting to return it to Radioddity because it appears to be used and had programming already on it from Germany of all places. Now the similar CPS for my Retevis RT-73 doesn't work correctly, letting me program the RT-73, but an error message pops up when trying to save the RT-73 code plug, with the Big Red X WARNING, to quit or try to continue, and a long incomprehensible dialog about the problem follows, even if I delete and reinstall the Ham made program by MM7DBT in the UK. 73 de W2CH Ray 62 years licensed an 80 years old, 100% Disabled Veteran from the Vietnam War, over 50 years ago.😊

Nice and I have a K4 and their amp and tuner. They are not Ethernet and I do wish they were. I use Node Red to make my system work.

I was one of the testers that contacted Retevis and they told me to send the prototype to them and they would send me a working model. Guess what they never sent me anything back after I paid to send the testing model back to them. How dirty of a company.
