foot to a foot and a half from the CB antenna.

My question is, if I transmit on 40 meters SSB at full power
(nominally 100 watts, actually more like about 70 watts or so), am I
likely to damage the front end of the CB radio? Will it matter if the
CB radio is turned on or off?

I could crank the power on the IC-706 back to as little as 10 watts
but it's going to be hard enough to raise any QSOs with the full 100
watts of power.

On the other hand, the motorcycle CB is big bucks to replace and I'd
be just as happy not to damage it...

Thanks...
If the CB is off, you are likely not to have problems. If it is on,
it is possible. I don't know how likely, tho, as the quality of the
front end may make all the difference.

The cost of a CB intigrated system radio on a Honda Goldwing is around $900
US and it's made by Panisonic. As for the FCC nabbing a motorcyclist for
operating his amateur radio on CB, well even if they could track him it's
not worth the effort. AKA how many truckers are using a lot more than 5
watts and you don't see many of them being targetted by the FCC. I know
because I used my 706 on 11 meters when my Cobra went up in smoke on me on a
trip to Arizona. And would you believe the state tropper in the Port of
entry scale was more interested in my scanner than anything else. And then
only till he found out I was a licenced amateur, then he wasn't interested
at all. What he told me was that state law had no aurthority to do anything
when it came to radios if I held an amateur radio licence. He said the last
thing they want is the Feds breathing down on him for causing trouble to a
licenced amateur radio operator, regardless if he's from Canada, USA or
Mexico it's the same thing. But now watch yourself in the state of
Washington, the FCC is hot and heavy in this state, I think it has a lot to
do with the military bases on the Pacific Northwest.
I had my 706 on my old GL1200 and it worked like a charm, mind you I didn't
run full power, a motorcyle battery is no where near as hefty as a car or
truck battery and my head is a little too close to the antenna to suite me.
You do know wher the term "hothead" came from.

Is it legal? No. Will he get caught? buy a lottery ticket, it may
stand a similar chance of hitting. I can't say what might happen that
he could get caught. People die of strange accidents every day and
crooks get caught even when they have the flawless plan. There is a
risk that he could get caught and the penalty would be in the
thousands of dollars. (or was the OP in canada?) Regardless, I
wouldn't recommend it. Raymond may have the better point... What is
his RF exposure?

I have to admit that this is one of the more benign suggestions for
using a rig out of band. I really suspect CB band is the safest place
to do this, but I really cringe when I hear someone say they want to
modify a rig so they can call the sheriff on his own frequency "in
case of life/death emergency." I read a lot of reports on those
too...

no, actually, i never looked that one up.

Personally, at 70 watts PEP on a motocycle, I'd be more concerned with
RF damage to the operator than I would be damage to any other
electronics...

Wouldn't that be closer to 100 w PEP? Icom 706.

The poster said 70, so I went with his numbers. I use an IC-720a, and
certainly don't go two-wheeled mobile with it. Hell, MY Goldwing
doesn't even have a fairing!
