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