ICOM
1- ICOM HF - VHF
Transceivers with 8 pin DIN Accessory ACC(1) connector to PC Sound
Card configured for PSK31; BPSK, and QPSK and other digital modes.
Please note that this interface utilizes transformer coupling, and
optocoupler Phototransistor
for software control of PTT.

2- ICOM Transceivers with 13
pin DIN data I/O port... for ICOM HF/VHF Transceivers; This circuit
employs an Opto-Coupler (phototransistor), and transformer coupling to
isolate the Sound Card from the transceiver (RF). ICOM HF / VHF
Transceivers with 13 pin DIN (ACC) connector to PC Sound Card configured
for PSK31 and SSTV modes. NOTE; This interface utilizes
the serial comport RTS signal to enable Push-To-Talk (PTT)
3- For the
ICOM, IC-706,
and IC-706MKII, The most popular of all IC-706 PSK, SSTV and
PacketBlasterTM© interfaces.
This interface also works with the IC-751, and similar ICOM HF/VHF
Transceivers equipped with 13 pin DIN ''ACC(1)'' connector to PC
Sound Card configured for PSK31, and other digital modes.
NOTE that this interface also works with the new ''PacketBlaster''
Sound Blaster compatible sound card program (No need for a TNC). This
this interface utilizes transformer coupling and enables software PTT
execution via serial comport RTS signal. ICOM models 706 etc...
4- ICOM
IC-706, 207, 281,
381, 481, 2000, 2350, 2340, and similar ICOM HF, VHF, and UHF
transceivers. This PSK31/SSTV interface uses the 4N25/PS2601,
Opto-Coupler (phototransistor), and transformer coupling to isolate the
Sound Card from the transceiver (RF). ICOM HF/VHF transceivers with
8 pin RJ-45 microphone connector to PC Sound Card for
PSK31 mode. Read the (C*) notes on diagram.
