HAMCOM REV 030809
|
I have been listening rhythm of a wood pecker
sitting on Neem tree around our house and so have been listening Morse
code. Both sounded same to me until late, when I started listening
with more attention.
Well they were different anyway!! In the sense
that, one was just hard work of a bird while other contained a
message.
|
|
Morse codes are irritating for many, me too. But
when I was 7 or so, dad started running a program called Hamcom on our
PC. It was fun to me because, I could type in a character and the PC
played a pitch of the wood pecker's hard work!
I loved that program. Recently we were working on
Science projects at our school & first thing came to my mind was
to make this simple PCB with just one IC.
You do not require this PCB/KIT if you only want
to practice Morse code. You may download the Hamcom software, install
it on your PC & start practicing Morse code.
|
You require this Kit only if you want to copy Morse
or radio teletype messages transmitted over radio. If you have a good
radio (SW) just add this card on your PC's com port & you can copy
Morse & RTTY signals. |
 |
This board is RS232 powered,
which means, you do not require to supply any power to it because it
takes its power from your computer.
The Program:
Hamcom is a free software written by a
German radio amateur with Call Sign DL5YEC . It requires a simple com
port interface to receive & transmit RTTY/CW on radio. With
this kit, you can start digital communication at very low cost &
in a shortest time slot.
Hamcom also includes audio spectrum analyzer and
tuning scope built into the software. My dad built this card 20 years
back but here I have made it again because, since then, there is not
much of the improvement in digital communication scenario around
here!!
 |
It is always better to "Type" &
"Read" on Computer than to give pain to ears!! |
Hamcom is not only for Digital
Communication or Morse code receiver/Transmit. This interface may be
used to copy Weather Fax and many other "Receive Only" modes
which requires simple computer interface and that too by almost
anybody with little efforts!! If you
decide to buy a kit, You will require few tools too. A soldering
iron, solder wire, a cutter and other small things, costing about $10.
