    I have a great Rockmite 40 qrp radio which is in a cabinet and has built-in speaker.
    The Rock-Mite is a crystal-controlled direct-conversion transceiver available for 80M, 40M, 30M or 20M. It features an on-board 8-pin PIC microcontroller which controls a T-R offset on key-down. A brief tap of a pushbutton control switch reverses the offset to yield a second operating frequency. Pushing and holding on the pushbutton activates the speed adjustment routine for the built-in Iambic keyer. If you'd rather use an external keyer or straight key, there's a 'drop-through' mode which allows use of an external keying source.

    You'll note in the image above that the Rock-Mite uses two crystals. The first is used in the local oscillator for transmitter and receiver. The second is used as a receiver front-end filter. This crystal significantly reduces the SWBC energy present at the receiver mixer; as a result, unwanted SWBC reception is dramatically reduced.
    SPECIFICATIONS:

    - 0.5W power output at 12V supply.
    - Supply voltage range 8-15V
    7030 kHz (QRP calling frequency)
    -automatic T/R offset, reversible
    -Built-in Iambic keyer, 5-40 WPM
    -Built in sidetone, 700 Hz

    I just noticed a mistake in the freq. This one is crystalled for 7.040 khz, not 7.030 khz. However, it is possible for you to change the crystal if you do not like 7.040.
    Tnx es 73 de Arnie W8DU
