Good Afternoon.
I was looking for some help on the feasability of an idea I have had
over on this side of the pond. I have a set of digital walkie
talkies (446MHz) and having played with a signal generator and an
osciloscope I have found that the input and output signal(9600) is
very clear with little to no distortion of the transmitted signal.
My final goal would be to have hypertermial on my PC recieving the
debug readouts from my Stamp on its com port. Does anyone
know how to physically interface these together. Initalialy it would
be half duplex communication from the robot side only. Maybe with a
view to full duplex if I can get it to work. (So I can shift the
processing power off the robot)
The walkie talkies have a microphone socket which I am still waiting
for the technical specs of.
The thought that I had was to connect a modem to my Com1 of the BS
and output the modified(for the correct voltages) signal to the input
of the walkie talkie and then another modem at the other end
connected to Com1 of my PC.
Would this work and has anyone tried to do this before?
Kind regards,
Andy T.

Interfacing Stamp to Hyper is quite easy. I am attaching a file named TWS.
Load this file into your Hyper directory, and create an icon on your desktop.
Load the program you want to run into Stamp, except make the debug statements
all serout 16, N9600 statements. When the program is running, exit the Stamp
editor, click on the TWS icon, and the data should start appearing on the
Hyper screen. If you have any problems contact me off-line. If you don't
get the download, contact me off line and I will send it again.

Since it is a text file, why don't you copy it in the body of your message.

It isn't a text file. It is a Hyperterminal file.

used 433 MHz Lynx modules for one way transfer. They work great if
you need to log data from a Stamp. They also offer transcievers for
more $$ but you could use Rx/Tx pair at 433 Mhz and another Rx/Tx
pair at 315 Mhz to do the same thing.
