      If you were to get a UK simple license for range testing purposes would it still be permitted to do so? Or does it have to be for a "business" type application only.

      UK Simple covers a specific frequency, 5w, mobile and portable. note 5w is ERP. You can talk about what you like, no politics, racism, music playing or re-transmitting someones voice. Get your M6, you can range test on VHF and UHF until your hearts content :)

    I wonder if anyone has tested the new Baofeng DM-5R or RD-5R series radios in the field on simplex channels recently. I find that the DM-5R gives quite clear reception on DMR. At currently under 50 UKP on a popular online auction site the DM-5R, would be a low cost introduction to DMR radio.

    Where do you buy all of your DMR radios from? Especially the motorolas. I'm not as interested in the Tytera MD-380. And where do you also find all of the older motorola DMR radios.

  • @galax574
    @galax574 5 років тому +2

    I think DMR works better than analog in both VHF and UHF. DMR definitely provides much more clear voice even at the edge of coverage. Some comments said that they encounter problems when using DMR at work. Could you give examples so that we can discuss.

    • @chamian1167
      @chamian1167 2 роки тому

      DMR while clear, loses voice quality. Voice quality refers to “how understandable are you”. With improper usage, in my experience dmr will lose clarity (sounds muffled). However, DMR has a lot of pros including DCDM/TDMA (dual timeslot operation for both simplex and repeaters) and the ability to encrypt audio.

    • @galax574
      @galax574 2 роки тому +2

      @@chamian1167 I think the occurrence of cheap Chinese DMR radios lowers the quality of DMR radios. When a Motorola DMR radio talks to another Motorola DMR radio, they literally will have no big problem; signalling features are compatible as well as voice is less robotic and understandable. But when other cheap Chinese DMR radios prompt out, the average quality is lower and signalling features are not compatible within brands. A correctly tuned DMR radio can sound as natural as other digital standards. It depends on how the user talks into the microphone, the audio profile of the radio and the brand of radio.

    Now I see why ham/DMR users say Baofeng is rubbish.
    On another note, the Kenwood performed as expected; crystal clear. Always loved how well they were built. The Motorola sounded nice too, though with a little tweaking it could sound just as good, if not better, than the Kenwood.

    • @radiosification
      @radiosification  6 років тому

      Not quite sure why you said that. The baofeng performed very well in this video. It's hard to see much difference between it and the kenwood.

    • @hcs4life21
      @hcs4life21 6 років тому

      +radiosification I had headphones on when watching this yesterday and heard a ton of static from the Baofeng, though I went through it again just now and still say the same but I noticed the actual voice clarity did pare well in comparison to the Kenwood...once I got past the static and really listened. Still say the Motorola fared best.

    • @radiosification
      @radiosification  6 років тому

      I do agree with you anyway that the kenwood is a far better radio. We had problems (not shown in the video) with my baofeng receiving interference from pagers on a different frequency. I could hear Bradley absolutely fine with a good signal when the pagers were not transmitting, but as soon as they started his signal was completely wiped out in the baofeng. This is due to its direct conversion receiver whereas the kenwood probably has super heterodyne and we had no problems with that. The baofeng did actually sound better than in the recording though. I remember being really surprised at how little noise there was, and then disappointed at how much there was in the recording. I think maybe it's thanks to the AGC in the camera I was using. In real life it sounded excellent (when it worked).

    • @hcs4life21
      @hcs4life21 6 років тому

      +radiosification I concur. I did seem to notice once the signal changed from digital to analog all radios fared worse across the board. That may have just been line-of-sight and what you mentioned before with the pagers and whatnot.
      How did the Motorola sound in real life as opposed to this recording? Were there any quality issues or differences when switching from digital to analog or vice versa?

    • @radiosification
      @radiosification  6 років тому +1

      Just note that we did not use digital on VHF at all. Only the motorola radios were using DMR mode as well as FM. The baofeng and kenwood were only operating in FM. Digital seemed to work very well here. It seemed to get through slightly better than FM on UHF. There were no issues switching between the modes, because you just program them in beforehand with the motorola radios, then in the field all you have to do is change the channel. The motorola sounded good in real life. I can't remember it really well enough to comment on the difference between real life and the recording. I did have an audio enhancement mode on though which increases the treble. There are a number of audio profiles to choose from in the menu of the radio. I think the audio might have sounded slightly better with it off actually.

  • @MotorsportsX

    can you guys explain why these radios have channels? is that just arbitrary and programmed into the radio by the end user?

    • @radiosification
      @radiosification  8 місяців тому +1

      Yes exactly. There's a programming software and you set the frequency and other details yourself for each channel. Businesses can have their own repeater and choose different channels for each group of people like cleaners, security and so on.

      Similar to how you have to get used to picking out words from background noise on analog, you kind of have to develop an ear for digital. Once you get used to it I feel like it's reasonably more comfortable to listen to as you don't get the fatiguing background noise
