This is another good example of why Dual Receive (using two TU's or
combination of a single TU and a sound card) on a single radio
is a big advantage over using a single demodulator.  In most cases,
the above example "599-61-62" can be figured out easily.  If not, a repeat
request is in order.  With all the flutter and strange sounding
signals over the last 8 hours of JARTS, I noticed the PK232 copied
as well as MMTTY in the flutter profile but the DXP-38 did not in
most cases.

For setting up dual receive on a single radio using WriteLog,
refer to my WriteLog website at http://www.geocities.com/writelog/.
