There are many optional shell, for example, metal cans, aluminum boxes, medical elongated aluminum box and so on. Select the box in time to pay attention as easy to open, because the battery ran out and need replacing. Recommendations: The confidential achieve better results, set the antenna performance can not be less than the full length of the horizontal half-wave dipole antenna, in conjunction with the use of Simple Barron, antennas should be kept away from sources of interference, such as fluorescent lights, computer monitors, switching power supplies and other equipment as much as possible with the coaxial cable as feeders to reduce possible interference received, as a small selection of the broadcast interference morning or late at night listening to get the best results listen to SSB and CW signals signal. Note: We don't supply any manuals please note about this before you order it. Package included: 1 x Shortwave Transmitter Receiver 7.023-7.026MHz QRP Pixie Kit
