[CQ-Contest] Need advice

Hi Dick,

If it's just RTTY SO2R that you are interested in, then you probably 
don't need a
DX Doubler. Depending on the software you use, you can probably accomplish
what you want with just a couple of serial ports and a simple interface 
on each
port. AA5AU's RTTY contesting site and the N1MM user manual should give you
a lot of ideas. A serial port can handle PTT and FSK keying (one port 
for each radio.)
All you need for receive is a stereo sound card with a line input, and 
the appropriate
cabling to your radios. You may need a simple resistor pad if your 
radios don't
have a line level output and you have to use the headphone output instead.

73, Kirk K4RO

I am considering getting a DX-Doubler unit and if anybody on the contesting reflectors is using a DX-Doubler, I'd certainly like to communicate with you about the abilities of the unit and whether or not it will be all that I need.  Or maybe something I shouldn't even consider.
