[RTTY] RTTY Digest, Vol 71, Issue 20, msg 3

[Dave AA6YQ]

The ST6000 RX out is RS-232 incompatible, but you may have difficulty
finding software that supports the required baud rate.

You can use an ST6000 as an "external modem" with a PK232, and then use an
application like WinWarbler that can run a PK-232 and the MMTTY engine
simultaneously for diversity decoding, or for decoding a DX station and
his/her pileup.

    73,

         Dave, AA6YQ

Hi Tom,

I have a full spec ST6000 on shelf since years.
I must have the manaul some where.
it will take a couple of days to locate it.

RX out is RS-232 compatible
you just have to make a special cable with DB9 at one end & a Molex
connector at the other one.

The demodulator is extremly simple just one 741 op amp per tone filter !
look here for some pictures
