App to make Yaesu VX-7R A Simplex/Duplex Repeater

[kd4e <doc@kd4e.com>]

Any chance someone might port this to Linux?

I am guessing it is fairly simple if it will run under
Win95 and up.

==================================

SIMPLEX is a program which manages a simplex or duplex 
repeater. It requires Win95 or later, 16 Mb of RAM and a 
sound card.

In Simplex mode, the repeater uses the same receive and 
transmit frequency. It records and replays alternatly the 
received signals.

This mode allows anybody who possesses a single transceiver 
to transform its station into a repeater.

The station will be able to repeat packet frames without the 
need of a TNC.

Your friends will be able to perform modulation and 
decommutation testing through your station while your are 
doing some gardening.

Any modulation may be recorded (SSB, FM, Packet, SSTV, PSK31 
etc).
Friends who cannot access a duplex repeater will be able to 
contact some more correspondants through your station.

In Duplex mode, the program acts just like a classical 
duplex repeater or transponder with tone opening, chat 
timer, beacon message etc. The program may replace a 
hardware repeater logic.

The duplex repeater mode requires separate receiver and 
transceiver working on different frequencies in the same band.

The duplex transponder mode requires two differents 
transceivers working on two different bands.

A more detailled description will be found in the chapters 
Simplex Mode, Duplex Repeater Mode and Duplex Transponder Mode.

Whatever the chosen mode, SIMPLEX is sensitive either to 
audio signals or radio signal to initiate the record process.

A radio signal is for example a squelch DC signal sent by 
your transceiver which goes high when carrier is received by 
the receiver and resets low when the frequency is clear.

In the later case, record will start on carrier detection 
just like a hardware repeater.

SIMPLEX may be used with CW, SSB, FM, SSTV or any other 
modulation mode.

SIMPLEX allows you also to play up to 11 different audio 
wave messages, 6 of which being looped if desired.

This will provide an efficient help to contesters as a parrot.

It is an intelligent parrot.

Please read carefully the help file SIMPLEX_EN.HLP before 
starting with SIMPLEX.

Connections between your home computer and your transceiver 
are described in the help. You will also find detailed 
schemes of the connection between the COM port and the PTT 
line of your transmitter in the joined file called 
PC_TX.BMP. (Note: CT-91 Cable Required For Connectivity).

Three examples are proposed : simplex repeater, duplex 
repeater, duplex transponder.
