Pactor 1 was licensed to AEA for example. But they did not get it working 
like the enventors did - problems with memory ARQ, the throughput was 
less than in the original. 

I think there are soundcard programs around that do Pactor 1. For my taste 
it is less than we want to have in performance. 

I built the TRX-PTC into my K2 (still low power version) and I am very 
satisfied with it. I was testing it /mm in Panama, Venezuela and Columbia, 
and in Crete and it worked very well. (using Airmail & Winlink 2000 and 
connecting my mailbox at home in OE9).

you see:

K2IO-board - bluetooth board - relais board (switch to Ptc-2 or ext. modem)
                    TRX-PTC board - EA3BLQ digital board
		speaker

For the use in our emergency service we rely on SCS modems, the price 
may be high but the performance and reliability makes it worth.

73!
