[FADCA] Would this work for HIGH speed?

[Bill Sinbine]

Do you think this might be a option to get some high speed links going with 
the Motorola radios?
If they have the proper frequency on the if this might be a option and 
would let us get above 19200 baud. This would come out less than the Tait 
radios are and would go much faster.
Does someone know if these would work in the radios we are using now?

I'm looking at putting one in my ft-847 for sat work and this is how I got 
the thought.

Just a snip from the web site listed below.

Amateur-satellites with 38400 Baud FSK-modulation (G3RUH) are in the orbit 
since 1999. First packet-radio digipeaters with 76 kBaud are operative in 
Germany. With the IFD, you can expand the capabilities of most amateur 
radio receivers to high speed data reception as 38400, 76800 and up to 
153600 Baud.

Principle of function: The IF signal of your amateur radio receiver is 
tapped directly behind the rf frontend (1st mixer) and connected to the 
input of the IFD module. There, the signal is converted to a second IF 
frequency of  10,7 MHz by a mixer circuit and a fixed frequency crystal 
oscillator. The IFD assembly is available for most common IF frequencies 
e.g. 71 MHz, 45 MHz, 21,4 MHz, 13,45 MHz or 47,43 MHz (FT736) or 10,7 MHz. 
The bandwidth of the IFD amplifier is standard 110 kHz for 76 kBit/s 
maximum data rate. Wider filters (300 kHz / 156 kBaud) or narrower types 
(80 kHz / 38 kBaud) are available upon request.
