Hi, I am looking for advice on how to integrate a PIC microchip with a
ham radio transciever. I will use this in a robot. I am looking for
100 - 300 mile range. I have a ham radio license.

Thanks for the help


Better pick up a copy of the FCC rule book and read it thoroughly before
embarking on this project to insure that it is legal.

That's a pretty tall order for a reliable 24/7 communications link to
a robot on the ground with a short whip antenna unless you use a
satellite link of some sort.

hi bob:

exactly. not to mention, you have data bandwidth limitations. you can't
do much legally with OP's 50MHz. if you have a commercial link it's
easy. for a commercial app we're looking at something along the lines of
plant control. I'd opt for a setup where i could check the status of the
bot via inet, cellphone, or satcom through a server at the plant
interfaced with those precertified 2.4Ghz links. 1Mbps! tell your bots
to do something. "hey, bot! pack a dozen cases of Bacardi." the bot
should have enough brains to do that, right? "make 500 line number blah
blah boards. oh yeah, and by the way, bot, here's the files. Have a
nice day! :-)"

hopefully, there's someone around if the bots go nuts. at least someone
who can shut 'em down before they drink all the Bacardi. assuming he/she
hasn't drunk it all him/herself. :-0

so if anyone's alive when things settle down, perhaps they could page
someone to pulease come in and fix things. if the plant computer detects
no life readings it would have to page someone itself :-(

a POTs setup would be good in tandem with this setup. call your plant
computer and use DTMF commands.

heh, heh... hope this works, right? better tell the security bot to be
extra alert.

BRs,
mike

aw hell.

i hope you're the AH i figure you for. if not, and this is just innocent
ignorance (is that possible?) don't take this too hard. just listen.

!-- if you are an AH... --
script language="AH_Blaster"
flame level=150%"

stop bs'ing.

1. if you have a license, you should know that you can only control
cars, boats, and aircraft at 1 watt which hopefully keeps the model
within eyesight.

i don't know what's legal for bot's, but AFAIK the max power will be .75
- 1 watt.

2. are you stupid? if you transmit that far or even just out of
eyesight, you'll

a) mung any legit R/C craft affected by your signal.
b) probably hurt someone with your POS robot.
c) cause a legit craft to hurt someone.
d) interfere with anyone communicating.


Thanks for the help

here's your help:

buy the most expensive books you can get until you're broke and can't
afford dangerous toys. go into debt to keep you out of trouble in the
future.

buy a cheap pic and glue it to a radio with no power cord or battery.
now it's "integrated."

/flame
/script

noscript
read a pic data sheet. PIC12F84A is pretty basic. get the software to go
with 'em.

figure out what you mean, next.

then ask more specific questions.
