    And what transmitting power does it show on CB?
    Can you transmit on the air band? do a test

      @@ianmooney4416 Not very good. Slightly better than UV-K5 but not well enough to consider using it as an HF or CB radio. It's a nice radio to have to test HF/CB rigs or to keep as an optional receiver, or just to have fun with. This radio is unique in the sense that it does tx/tx more or less on every ham band straight out of the box. No trickery or firmware upgrade needed.

    How about the reception sensitivity on PMR 446? comparable to dedicated PMRs like Motorola or Midland?

      @@Borg1of47 Depends on which Motorola. Reception is good, though I found the squelch is quite open on PMR. I'd say fairly sensitive. I joined a PMR net recently and this thing picked up bits and pieces that my UV-K5 didn't.

    Got my Radtel RT-900 the other day. However i think the recieve is not as good as the Anytone on weaker signals, ie 2M/70cm. The background noice floor level is higher and also the squelch is harder set on the lowest squelch setting with the same antenna so it wont open. The sound quality is a little bit squeeky from the speaker and the modulation from RX stations on a distance is harder to hear due to this. However, for the money it is a ok radio for more shorter distances. Maybe future software updates can make the radio sound quality better.

    • @RadioRofi
      @RadioRofi  3 วันที่ผ่านมา +1

      Hi, thanks. Appreciate you sharing your experience. You're right about the high noise floor, I've seen it on other Radtels as well. I've been fairly impressed with the reception actually. I haven't used it as an open squelch station to work very weak signals to be honest. I think a base station radio is better suited for that. In range testing, working repeaters etc it performed well. I'm surprised to hear you didn't like the sound quality, I thought it was a strong point really.

    • @TobiasTheAviator
      @TobiasTheAviator 3 วันที่ผ่านมา

      @RadioRofi yes, an interesting radio. However, have listened with a better antenna today. It would also have a little bit much of a squelch tail to it. There is a setting for it in the software, but it won't change anything from user perspective what i can determine, have tried all different settings there. Something you have worked out?
