Mike,

I use an FT-847 on 2m converted to 1268 by a 15w transmitting 
converter that was made by DEMI (original cost $450).  However it is 
no longer made by them.  They tooled up before AO-40 failed and got 
stuck with inventory with no market.  I suspect that they will not 
make another until an established Heo is orbiting on mode-L.  Not 
enough market for them.

It is my understanding that Kuhne Engineering in Germany is producing 
a 144/1268 Tx converter:

It only outputs 1w so you would need a PA to follow it:
http://www.kuhne-electronic.de/en/shop/142_Leistungsverstaerker/article:206_MKU_PA_1330_A

this would give you 30w.

You can order from Kuhne directly from Germany.  They have a dealer 
in the US: ssbusa, but I do not recommend them either on cost or 
speed of delivery.  You will pay shipping from Europe and have to 
transfer funds into Euros.  Kuhne equipment is excellent quality but 
at a price.  I did not find a price page so you may have to e-mai for 
info.  Michael Kuhne is DB6NT, a well respected mw engineer and mw ham.
