Transmit
The allowed transmit frequencies are: 7.0-7.2MHz, 10.1-10.15MHz, 14.0-14.35MHz. When sending a message in
these frequency ranges, the display will show TX, the S meter under the LCD will change to display the transmit
power P. There are 3 scales on the transmit power scale except for the 0 scale. The approximate power of the first
scale is 1W, the second scale (slim one) is about 3W, and the third scale is about 5W (because the radio detects the
RF voltage output to the antenna port, so the displayed power is only accurate when the SWR is close to 1:1 ).
When the signal is not sent in these frequency ranges, it will be invalid. The display will show NO. At this time, no
signal will be sent from the antenna, but the side tone can still be heard. This feature can be used as a morse code
trainer.
CQ & Auto CQ
1．Auto CQ
Short press the CQ button and release it immediately, that is, enter the automatic call program, the content of the call is input by the user, and
the input method is described below. After automatically calling the content entered by the users on both sides, the radio station automatically
adds a K to end the automatic call. If you want to cancel the automatic call during the automatic call, press the CQ button for 1 second and
then release it.
The following 2 and 3 functions can only be operated in the paddle mode, and they are invalid when keyed by hand.
2. Speed
Press the CQ button and hold it down, about 2 seconds later, you will hear a beep (Morse code letter S). At this time, release the CQ button to
increase the speed of the automatic key paddle to "dot" and dial to "swipe" The speed slows down. You can reach the appropriate speed (it
will automatically exit after 8 seconds without input and maintain the original speed). Press the CQ button for a short time to release it
immediately, and exit when you hear a beep (Morse code letter E), or wait for about 8 seconds to exit automatically.
3. Edit CQ message
Press the CQ button and hold it down. After about 2 seconds, you will hear a beep (Morse code letter S). Continue to press and hold the CQ
button. After about 2 seconds, you will hear a beep (Morse code letter I). At this time, release the CQ button, and use the automatic key
paddle to send the content you want to enter as usual. At this time, press the CQ button and release it immediately, and you will exit when you
hear a beep (Morse code letter E). . For example, if you enter the content of CQ CQ DE BA4TB, the following content will be automatically
shot and sent during automatic call: CQ CQ DE BA4TB CQ CQ DE BA4TB K
When in speed adjustment and call sign input modes, the display will show the word TX but will not transmit signals to the antenna, which is
normal.
4. CQ message’s length
The automatic call storage capacity in the radio station can store about 20 characters. Because the code length of
each character is different, the number of characters that the memory can store is also different. If the number of
characters entered exceeds the content of the memory, the radio will not be able to Store, the radio will clear the
contents of the memory at this time.
