Does it have to be stereo?
Vega and Lectronics make some nice gadgets for IFB, but they are all mono.
You might also look at some of the in-ear monitor systems. Stereo, but
generally poorer sound quality than the IFB stuff.
There are also some systems that are intended for assisted listening
applications. In the US they are either infrared or they use the 72 MC
band. These tend to have much greater range, but they have the poorest
sound quality of the three.
300 meters is pushing it on all of these but you might be able to do it
under the right conditions.

** Is that 300m through solid rock, a forest full of conifers, from one
submarine to another, from one subway station the next ????
Or it is open range across water or desert ?
Or something in between like a crowded auditorium

Take a look at the Zaxcom digital stereo receiver and 2 channel
transmitter. www.zaxcom.com
About $3600 for the set.

Yeah, but the OP asked about 300M broadcasting, so regardless, it's against
the law in America.

I think in America, the 300M band is used for navigation beacons.
--scott
Seriously, though, I think you can easily do 300m distance, but you're going
to need a licensed system, like the Lectrosonic stuff. The reason we have
licensing is so that people don't step on one another, and working on a
licensed band also keeps other people from stepping on you inadvertently.

The Lectrosonic wireless mics can reach that(1000 feet) line of sight |
no license needed
I don't know of a headset that would do that though

If you are under very good conditions and are careful, you can often do
that. I wouldn't want to count on it on a regular basis, though.
Yes, a license is needed to operate ANY of the Lectro wireless mikes.
In the US, anyway. You _must_ fill out the form and send your check in
to the FCC. Do not operate these things without getting the license.

The Lectro IFB boxes have comparable electronics to the wireless mikes.

I asked Karl Winkler about this at AES he told me No license was needed |
and he would promise 600 feet under the worst condition with 1000 feet
being the assumed nominal range

Karl? Is this right? No more Form 34s?

Well, you know how these promises are when you hear them at a trade
show...
Most of our transmitters operate at 100mW (some are at 70 and some are
at 250) and thus have greater range than the more common units
operating at 30mW or under (most of the lower-cost units on the
market) and even a bit more than the units operating at 50mW (high-end
Sennheiser, etc.) 600 ft is usually well within the range of a 100mW
transmitter and well-filtered receiver. 1000 ft. is certainly possible
as well, depending on conditions. We do not "promise" that kind of
performance (nor would any wireless manufacturer), but our systems are
well regarded for good range and resistance to interference.
Here's what I know about the license issue: for VHF devices under 50mW
and UHF devices under 250mW, they are classified by the FCC as
something like "auxilliary TV transmitters". For applications involved
with TV production, they should be licensed. For anything NOT
involving TV production (i.e. stage, touring, etc.) they are ILLEGAL.
Doesn't matter who makes them: Shure, Lectrosonics, Sennheiser, etc.
However, the FCC basically looks the other way because there is NO WAY
they could actually regulate their use. There are millions of systems
out there, and thousands more each day.
So basically, don't worry about it, unless you feel like making a
donation to the FCC.
This is of course not the "officially sanctioned response reviewed by
lawyers" but instead the practical, real world one.

This is the case for anything using the broadcast auxillary services
channels. Which I strongly recommend using if you can, because they
are hardly ever used.

This is not the case for the "wireless mike" channels, which are legal for
anyone to use if they have filled out the paperwork. Or at least, that
is the way it used to be.

Bill McFadden's Wireless FAQ is here:
http://groups.google.com/groups?q=%22wireless+microphone+faq%22&hl=en&lr=&ie=UTF-8&selm=1993Dec1.081815.1719%40tvnews.tv.tek.com&rnum=1
It used to be posted periodically to this group but it's been a long time
since I have seen it and it may not have been updated in a while.
I'm still trying to get a straight answer on the legality of using the
low-band VHF wireless systems. I have a license form for one, dated 1976.
Nobody knows if the itinerant use channels are still legal for wireless
down there, at least nobody that I talked to.
And, all the information I have may be totally wrong, since the FCC is
currently a disorganized mess and regulations seem to be in constant flux.

Well, I guess if you turn on the receiver and don't hear anything,
that's a good sign that the channels are unused. <g>
