If the PC and external equipment are not modulating on your Kenwood Transceiver, confirm that the setting of Menu No. 63 matches the input terminal for the external equipment.
Why is my Kenwood Transceiver not receiving signals?
If you're experiencing poor receive sensitivity on your Kenwood Transceiver, consider the following: * Ensure the SQL control is not fully clockwise; turn it counterclockwise. * Check if the Attenuator is ON; if so, switch it OFF by pressing [ATT (RX ANT)]. * Release MIC [PTT] if it's pressed. * Review 'DSP FILTERS' and ensure the IF filter bandwidth is correctly set. * Verify the correct antenna connector (ANT 1 or ANT 2) is selected by pressing and holding [PRE (ANT 1/2)]. * Ensure the pre-amplifier is ON by pressing [PRE (ANT 1/2)]. * If an internal DSP error occurs, restart the transceiver. If the issue continues, consult Kenwood authorized Service Center.
Why can't I transmit with my Kenwood TS-590S?
If you're unable to transmit with your Kenwood Transceiver, even when pressing MIC [PTT], consider these potential causes: * Ensure the microphone plug is fully inserted into the MIC connector after turning the power OFF and checking for foreign objects. * Verify the Transmit Inhibit function is OFF by changing Menu No. 60 to OFF. * Select the correct voice mode instead of CW or FSK. * Adjust the DSP TX filter bandwidth settings in Menu Nos. 25, 26. * Ensure the correct antenna connector (ANT 1 or ANT 2) is selected by pressing and holding [PRE (ANT 1/2)].
Why is my Kenwood TS-590S display showing incorrect digits?
If your Kenwood Transceiver isn't functioning normally after being switched on, with incorrect or missing digits on the display, check the following: * Ensure the input voltage is within the range of 13.8 V DC ±15% (11.7 ~ 15.8 V DC). Correct the input voltage or use a 12 ~ 16 V battery. * If the microprocessor has malfunctioned, review 'MICROPROCESSOR RESET', and then perform a VFO Reset. If the problem persists, perform a Full Reset.
Why is SSB audio quality poor on my Kenwood TS-590S Transceiver?
If the SSB audio quality on your Kenwood Transceiver is poor, with missing high or low frequencies, check the following: * Ensure the correct operation mode (USB or LSB) is selected for the receiver. * Adjust the DSP filter width by turning the HI/SHIFT or LO/WIDTH control. * Turn OFF Noise Reduction 1 or 2 by pressing [NR (LEV)] until the NR function is OFF. * Turn OFF Beat Cancel 1 or 2 by pressing [BC (A.NOTCH)] until the BC function is OFF.
Why does AT not finish successfully on Kenwood TS-590S Transceiver?
If AT does not finish successfully on your Kenwood Transceiver, the impedance of the coaxial cable and antenna may not be matched. Adjust the antenna system to lower the SWR.
Why won't my Kenwood Transceiver Memory Scan start?
If Memory Scan won't start on your Kenwood Transceiver, consider these potential causes: * Adjust the SQL control to just eliminate background noise. * Unlock at least 2 memory channels. * Store data in at least 2 memory channels.
Why is Program Scan not working on my Kenwood Transceiver?
If Program Scan won't start on your Kenwood Transceiver, it may be because the start and end frequencies are identical. Store different start and end frequencies.
Why does Kenwood TS-590S output power seem low in SSB mode?
If the transceiver output power seems to be low in SSB mode, apply a continuous single tone (1 kHz) to the microphone audio input to measure the RF output power. The PEP will be the same as this RF output level.
Why does Kenwood TS-590S output power decrease after short time?
If your Kenwood Transceiver's output power decreases after a short operating time: * Contact a Kenwood authorized service center to clean the air filters, as they may be congested with dust. * Relocate the transceiver to ensure adequate airflow for cooling.
