This picture indicating the caps in broadband receiving position

The LED at the right corner of the main board indicates the IF working state. It flashes at
very strong signals because of the AGC function.

To transmit signal

TJ5A transmits in the following frequency range:

Meter Band

Frequency Range

40m

7.000000 – 7.300000

20m

14.000000 – 14.350000

15m

21.000000 – 21.450000

10m

28.000000 – 29.700000

Note:

The band pass filter is tuned to the center of the band. Therefore, the transmitting power might be

affected at band edges.

SSB operation

In LSB or USB mode, press PTT to enter transmission mode. Speak to the MIC and your
voice is transmitted. Output power can be observed on the power meter. The output
power can be adjusted through

PWR

knob. Do not operate CW key in LSB or USB mode,

because the side tone from the speaker goes into MIC, causing a strange CW signal, the
combination of 950 Hz and the carrier.
