What kind of frequencies can a Kenwood ts-440 receive?

What kind of frequencies can a Kenwood ts-440 receive?

One great feature, which has since become standard on HF radios, is continuous receive on all SW bands. In the case of the TS-440, all frequencies from 100 KHz up to 30 MHz can be received. With the MARS modification, transmission on these frequencies is also possible. It was also, for the day, compact and of light weight.

Where is the audio jack on a Kenwood ts-440?

This Modification allows for the Kenwood TS-440s transceiver to have the data audio on PIN 11 of the 13 pin DIN connector ACC JACK 2. Later models may or maynot have a correction for this, but my PK-232, or for that fact NONE of my TNC’s would drive the audio to the PIN 11 of ACC JACK 2.

Where can I get help with my ts-440 transceiver?

Another big help is the TS-440 Yahoo group: TS-440. Troubleshooting a transceiver is a complicated task. There are thousands of components, and dozens of wires, connectors, and cables. The obvious: Is the circuit getting power?

Is the Kenwood ts-440 a Legends of ham radio?

The Kenwood TS-440 is one of the legends of ham radio. Over 600,000 of these radios were produced in the early eighties (this number has been disputed, so I am doing some more research – if anyone has verifiable production numbers I would appreciate the information and the source), giving it the largest production numbers of any HF ham radio.

How do you change the antenna on a Kenwood ts-440?

Remove the FOUR screws holding the AUTOMATIC ANTENNA TUNER. Place the transceiver on it’s side with the BOTTOM towards you, and the FRONT to your LEFT. Being very careful, remove the antenna tuner and allow it to hang. Remove the TWO SCREWS that HOLD the AFSK INPUT board.

Which is better Kenwood TS-520 or ts-440?

There was also the matter of power consumption. The tube models tend to use much more power. The final Kenwood hybrid (TS-520) used 5 amps when receiving, compared to 1.9 amps on the TS-440. Pure tube radios could use even more.

Why does my Kenwood ts-440 sound weird?

This is very bad in VCO circuits, where the varicap diode is extremely sensitive to any voltage change. If a TS-440 has conductive glue in the VCO circuits, it may sound distorted when receiving a signal and transmitted SSB sounds strange.

Is the Kenwood ts-440 a good ham radio?

Though more recent radios have offered more features, DSP and other new technology, and easier integration with computers, the TS-440 may have reached a point where there is nothing more really needed. This is, for the present, the heart of my ham station.
