[RTTY] The magic of TU

[John]

Hi Chen,

What do you think leads to the signals I heard last weekend that have a short "chirp" at the beginning of each transmission?  (not RSID) There's a short space tone, followed by a short mark tone, followed by the Baudot message.  I kept track of some of the calls I heard with this distinctive signal if it would help.
