Some tips and tricks for the Kenwood TS-590S

• If you need very low TX output for modes like WSPR you can use the  DRV output. Push the DRV button and for TX the DRV output will be used and that is about 1 mW depending on the TX power setting. For RX the normal antenna will be used.
  
  
• Listening to AM broadcast stations you can set the bandwidth control up to 5 kHz wide but beware this is per sideband so in AM the bandwidth is actually twice that wide. Normally a broadcast in AM is 9 kHz wide so the 10 kHz available is more than enough.
  
  
• The option to buy a TXCO from Kenwood is expensive. A cheap Chinese TCXO works too and only costs about 12 euro. Search for them on eBay or AliExpress. The cheap price has the disadvantage that this cheap TCXO introduces extra noise to the receiver especially on 50 MHz.

• The power output varies according to the voltage given by the power supply. The manual states that 13.8 Volts of power is needed. On 12 Volts the rig only gives a maximum of 50 Watts. Full power of  100 Watt output is reached with a power supply of 14 Volts.
  
  
• Remember that as the manual states the on-board power meter gives an average power reading in SSB.
  
  
• To send recorded audio messages without touching the PTT or send button, set the VOX to On and VOX level to 0.
  
  
• To expand the transmit range of the transceiver remove resistor R900. The expanded transmit  range is 0 to 30 MHz. There is no TX between 30 and 48 MHz.
