From the makers of the Spitfire AM transmitter comes the Mosquito 1-Watt Am Transmitter.
Could be a great start to a carrier current setup. $111.00 US Dollars.

Is there a link to this new thing?

I linked to the 6V6 website at the bottom of the original blog post but I can place it here in my response as well.

Wow, the 6V6 Line of Transmitters is very interesting!

We will be watching those!

Says 1 watt(AM) is a new standard some countries are adopting but here?

Their pitch is a bit of a strech.  "One watt low power standards being adopted worldwide" translates to : In the Netherlands if you have a new LPAM license, and Sweden, Norway, Denmark and Finland".  That's hardly "world wide"  5 out of 196 countries and Netherlands requires a license. 

It's also "optimized" for 50% modulation (apparently a requirement in the Netherlands) but can modulate up to 110%.  Not bad, but more is better. More modulation = increased useable range. 

Not reallly useable in the USA unless you're prepared to bring output within specs.  As for carrier current applications, I have no comment as I've never paid much attention to carrier current rules.

But it should be a dandy in a very few parts of the world.

Tim in Bovey has covered most important points about the Mosquito as far as we are concerned here in part 15 land.

Having my curiosity aroused I've looked at the link three times and will add some more remarks:

There is a version marked "1 Watt US", which sure sounds like it's designed for the US market, but it can't be.

For one thing it's fully-built but uncertified which means it can't legally be sold in the US.

For another thing there is no mention of an RF power control, which would would put the burden on the user to build an attenuator circuit to "throw away" anything above about 60 mW. Most hobbyists would be out of their league trying to manage such a feat. Anyway, it will still be "illegal" because it would have "more than 100 mW to the final RF stage", given the fact that almost everyone considers the final RF stage to be the last amplifier in the circuit.
