DATA FSK CW  Isoterm Traveller

 This  TRAVELLER Interface is an update on the previous FSK/CW Model.

Its nice and compact and well suited for  portable/holiday use.

NEW silk screened panels are now standard.

It now allows the usual PSK Data modes as well as FSK and CW TX/RX.

This is now a switchable model allowing FSK or CW to be selected in the Coms port plug.

In the CW configaration the Front Panel Jack socket is the Morse Key input.

While the REAR Panel jack socket goes to the CW Key input of the rig.

In the FSK configaration the  Rear Jack socket has the FSK RTTY switching

signal present. As well as the ability to have the FSK switching signal to be an integral core within the DATA cable

With an on board mini switch accessible through the bottom of the interface.

Dependant on the rig to in question.

One RED TX and One GREEN RX front panel mounted  Leds show PTT switching activity.

The interchangeable cable allows the interface to be used with any transceiver.

The cable is terminated in a 6 Pin Mini Din plug to fit the interface and whatever

Plug is required to suit the rig it is being purchased to for.

Some rigs will have the FSK switching as part of the DATA mode cable

Others may need a separate cables as well as the DATA cable, this is supplied in the price.

Only needing a change of cable to be plugged in ,to suit a new transceivers connections.

There are both Rx waterfall and  Tx attenuator controls front panel mounted for operator convenience.

All paths between COMPUTER and TRANSCEIVER are isolated with

TRANSFORMERS in BOTH AUDIO LINES.

And a DIL RELAY in the PTT LINE

The CW-FSK keying circuit is an OPTO ISOLATOR so continues the isolation on all modes

The Dil Relay for PTT control allows ALL rigs to have the PTT controlled from the software.

So no matter what rigs you intend to use, this unit will take care of the PTT switching.

On the computer side 2 – 3.5mm stereo jack plugs and a 9 Pin D connector are terminated .

This can of course be driven from the usual RS232 to USB adaptor cable.

I can supply various versions if required.

Extruded aluminum box , 80mm Deep – 55 mm wide – 24mm High.

These two jacks are plugged into the Soundboard's LINE IN/ LINE OUT jack sockets.

Or if a laptop is to be used , its Mike and Headphone Jack Sockets.

With the 9 Pin D being connected to the Com's port of your computer, for PTT SWITCHING and CW -FSK Keying.

Both RTS for PTT  and DTR (CW) or TXD (FSK)  pins are connected in the 9 Pin D connector as required.

Mode selection between FSK and CW is done by a slider swithch in the Com port 9 Pin D connector.

Both RX and  TX attenuators  are accessible .

This along with the PC Soundboard Audio controls helps prevent overdriving of the Rig.

And less traveling back and forwards to the Soundboard Sliders.

ALL ISOTERM interfaces are also suitable for SSTV-RTTY-PSK-31-WSJT and most other

Soundboard based data modes

This TRAVELLER INTERFACE extends the modes to FSK and CW.

A suitable program for FSK RTTY is of course MMTTY.

__________

KH6TY DIGIPAN software for PSK MODEs is supplied.

Along with CWGET and CWTYPE for CW operation as well as MMTTY for FSK.

Information is also given on other web sites for additional PSK31- SSTV-RTTY – CW info/software.

Full setting up instructions are of course supplied.

Extra sheets of instructions are enclosed to help further.

FULLY WIRED means ALL plugs to suit both Computer and 1 Transceiver .

I am prepared to taylor the cables to suit individual customers should this be an advantage

if shorter cable would make a laptop installation more compact.
