Rezumat
- It is recommended to use a full-length half wave dipole antenna or an antenna system with equivalent performance. Choose a time period with less interference and good propagation conditions for communication, and it is recommended to make an appointment with a friend station for communication.
- Typical reliable communication distance: 150-300 kilometers, and the distance can be further increased under excellent propagation conditions.
- After actual comparative testing, it was found that in a well propagating environment, the reception effect of this machine on remote signals is not significantly different from that of commercial shortwave radio stations such as FT80C, which is surprising.
- Amateur radio enthusiasts (especially CW operators), shortwave DIY players, QRP communication enthusiasts, school radio clubs, electronic training courses, emergency communication disaster preparedness kits.

Features:
It is a 40 meter band low-power equal amplitude telegraph transceiver designed specifically for CW enthusiasts, with a center frequency of 7.023MHz. When the transmission conditions are good, reliable communication can be achieved with amateur radio stations within hundreds of kilometers. The circuit originates from classic foreign designs and has excellent frequency stability, selectivity, and receiving sensitivity after optimization. It is a practical equipment for amateur radio operators to perform CW communication.
Operating frequency: 7.023-7.026 MHz (crystal oscillator stable frequency)
Working mode: CW (equal amplitude telegram)
Power supply voltage: 9V-15V
Receiving static current: 12mA @ 12V
Transmission power: 13.8V/3W; 12V / 2W
Antenna impedance: 50 Ω, unbalanced type
Receiving sensitivity: better than -116dBm
