    I have the same radio. The microphone does work on mine. I use it with 13.8 volts for a little more punch. Made several rather contacts long distance POTA contacts, from TN to CT, NY,and yesterday Oregon and Washington St. on 40 meters at night. Interesting because I really operate as a portable in my backyard. So it’s two portables communicating long distance.
    One though, it’s kind of frustrating not being heard by a loud DX station. By the second skip the 5-10 watt signal has probably completely dissipated.

    Hi. There is a vid on my channel how to fix microphone problems and how to rewire microphone. Cheers from old George

    I have got the same transceiver. It works pretty well. But I have problems using SSB. The sended audio is very bad even with the internal micropgone. 0:07 Which Settings do you use?

    I have it now, works perfect for digital modes and CW but the TX voice quality suffers on SSB from distortion. Audio from speaker is good. I use it for FT8 and JS8CALL and have made hundreds of contacts up to 7000 kms away with nothing more than a random wire and tuner. Backlight off option doesn't work (backlight always on) and there is no charge or battery level indicators and the included mic is garbage. Battery life is long (big battery). You can select 160 and 6 meters but they don't work. There is 9 working bands not 8. Power is best on 40 and 20 meters (10 watts) and it doesn't get warm. It does get warm on frequencies higher than 14 mhz and power output drops significantly.

      Centar1964, same experience here, fun little CW rig and have worked around the world with it on CW and a dipole. The rotary encoder is flaky and I don't dare try to adjust anything mid QSO as it would alter anything randomly. One wrong move and mid QSO it might switch to VFO A instead of B while trying to change bandwidth etc. Once I've started into a a CW QSO I adjust and touch nothing LOL. A rig like this is not for the inexperienced Op as it would be a poor intro to QRP and Ham radio in general. But as a modern and economical replacement for the HW-8 and other rigs I had as a youth it's good enough. My record with it for distance was 7,500 miles and on 10 meters. On 10m it only produces about 1.75 watts. Good toy for experienced Ops and a fun challenge.

    Can this be used as a general coverage receiver outside of the ham bands?

    • @KB2CWN
      @KB2CWN  9 місяців тому

      Yes but with poor results. There are many betters receivers at the same price range that would better serve as a general coverage receiver.

      Sensitivity, stability, selectivity etc. Buy a tecsun, this does well for hamming only
