HF 10W amp





Ebay Description


10W Radio shortware CW Transmitter 7.023MHz Kits 
 HF amplifer 5-9MHz 40dB Ham

It is kits, you should solder by yourself. You can use 6-8Mhz 
Crystal  replace 7.023Mhz crystal without do any change.
it is  newest  product of our company, it is not only a CW Transmitter but also a HF power amplifier.we can provide datasheet. after you receive it , we will send the datasheet for you by email. 
power supply:
     input voltage       Working current(A)       output voltage Vpp (V)    output power(W)
         6V                          0.53                                     25.30                             1.6
        7.2V                        0.67                                     33.4                               2.79
       8.4 V                        0.78                                     39.2                               3.84
      9V                             0.82                                     42                                  4.41
     10.00V                       0.9                                       46                                 5.29
     12 V                           1.07                                     55.80                             7.78
