Upgrading PSK 31 interface.

psk 31 interface is under construction...

After succesful with the ugly interface for psk 31.... now i try to make another interface for psk31. This time i try make full function interface.

ICOM RIG INTERFACING

In order to connect your Icom radio to a comp for CAT control, you will need a converter that is capable of converting RS232 levels to icom 5 volt collector bus line.

There are several ways to go about this, ranging from very basic two transistor interface to ICOM own CT-17 interface.

The obvious answer is to purchase ICOM CT-17. Its cost US 14o...This cannot be considered inexpensive by any standards. It is relatively simple to build the inteface from the circuit found in the internet. This is the design used by HB9DRV and PH1PH when testing Ham Radio Deluxe. Total Building araound $25....

Litar CT-17

Component List :

IC1 DIL16, MAX232 - BELUM JUMPA LAGI...HUHU...tapi ody kata dia jumpe..
SC1 Socket DIL16
Capasitor 1 x 10uf, 4 x 1uf,
capasitot seramik 1 x 0.1 uf
2 diode, 1n4148
1 zener diode, 4.7v
1 resistor 220

To be continued........

AUDIO INTERFACING

If u are planning on using PSK31 Deluxe (or any other soundcard mode) you will need an audio interface to connect your rig audio in/out to the computer soundcard.....

Audio interfacing can be done in so many ways.... It is possible to connect your radio directly to your soundcard without any form of isolating interface but this is cannot recommended.

I shall assume that you want to do things properly, so here is a circuit that has proved its worth many times....
