Prog7k & DTMF_Txer

 

Some years ago I got tired of trying to key in all the programming codes for my repeater controller using the DTMF pad on my HT so I thought up an encoder for the computer and wrote a DOS application to send a txt file to the controller. The result was the DTMF_Txer and Prog7k.

 

DTMF_Txer was a small PCB that connected to the printer port of a WinTel, (IBM) pc and your HT or radio. It generated the DTMF tones for transmission. Prog7k was the application that controlled it.

 

Prog7k allowed you to create a programming, or command file with comments and it would lookup the correct programming codes for CW characters. In addition, I also added the capability for the program to lookup the code for speech synthesizer words.

82 30                        ;DTMF interdigit 3 sec

63 03 1                     ;DTMF mute ENABLE

96 7                           ;DTMF mute delay 7 sec

 

Anyway, it worked and saved me from using the keypad on the radio to program my controller.

 

So here is the link if you want to download the distribution: Prog7k.zip

 

There are schematics for each of the two different encoding devices used. You can derive a parts list from the schematics.

 

Read the doc's. Keep in mind this is a DOS program. It runs fine in a WIN95/98 environment. I have never tested it on ME or 2000. I have had problems with 'fast' cpu's, over 500Mhz? Your mileage will vary.

 

If you have questions you can email me at my call, (WD8KNL) at QSL dot net.
