[RTTY] Contest exchanges:Adding their call

[Al Kozakiewicz]

It's not necessarily the squelch.  This happens when running on noisy/congested bands with AFC on.

I had several times when running that I'd be called by folks who apparently took the brevity advice on this reflector from last year to heart and would call sending their callsign just once. No DE, no AB2ZY DE.  What do you think is going to happen if AFC is on and MMTTY is off chasing the noise on 40m or an adjacent signal?  They're 599 and I have to send AGN? 2 or 3 times before I can catch the full callsign and not just the suffix.

Your decoder squelch may have a settling time to establish its threshold.  I like to run with squelch OFF, or at least set well below prevailing signal levels.  You get more garbage characters in the absence of any signals, but that is really not a problem. 
Whenever a signal is present, the garbage stops printing.

In MMTTY, click the SQ button to turn squelch off, or left-click in the green area to set the squelch to a low level.  The squelch threshold is indicated by the thin black line in the green signal area.  You can move the line around by left-clicking in that window.

It is also possible that your rig is taking a while to set its receive agc level.  Turning RF gain down, and using fast AGC may help with that.
