Description
This is a one-owner Kenwood TS-440S Amateur HF Transceiver. It covers all amateur radio bands from 160M through 10M. The receiver frequency range is spec'd at 100 kHz to 30 MHz. Operating modes include LSB, USB, CW, AM, FM, and FSK.This unit has the built-in automatic antenna tuner and is offered for sale with the 12VDC power cable, original instruction manual, and photocopied service manual. A microphone is not provided and you will also need a 12VDC power source and suitable antenna.
The cosmetic condition is good with minor scratches on the cabinet. The left side has the worst scratches; see detailed photo.
I tested the transceiver, and my findings are offered for your consideration while deciding whether you have interest in purchasing this unit.
Receiver Evaluation:
The receiver will barely detect the minimum RF signal produced by my HP 8642B signal generator, at -140 dBm or 0.023 uV. Typically, the signal strength needed for an S9 reading when in LSB or USB is around 110 - 120 uV. All amateur bands were tested and similar results occurred on each band.
When using CW and the narrow IF bandwidth filter, the S-meter reading will drop around 2-3 S units compared to the reading when using the wider IF filter associated with LSB or USB.
Receiver frequency readings are dead on compared to my signal generator. The frequency readout resolution is to 0.1 kHz.
Transmitter Evaluation:
I attached a Kenwood microphone (not included in sale) and tested LSB, USB, AM and FM modes. I did not test CW or FSK. The transmitter produced appropriate power in the tested modes. In fact, the transmitter will operate not just within the amateur radio bands, which is good if you have a MARS license. Otherwise, be very careful when keying up the transmitter to ensure your transmit frequency is within the bands you are authorized to operate in.
The meter appears to correctly display ALC level, Power, and SWR when transmitting. The Power readings appear to be peak power measurements. The maximum indicated power readings range from around 90W to 100W in the various amateur bands.
