135kHz band CW transmitter TX2200A
It is a radio transmitter for the 135kHz band newly permitted for amateur radio.
To operate on board, the power supply is 13.8V.
The FWD power and the REV power are displayed in the meter. The match with the antenna can be confirmed at any time. |
|
The frequency is changed by the rotary dial. The variable step can be chosen from 10Hz and 100Hz with the switch. |
There are two types of output power. (50W for mobile and 100W for fixed). |
|
The antenna tuner circuit is not built into. |
