Maybe it's my turn to ask a dumb question. 1. If I send ALL QTCs, they go as expected and everything is fine. 2. If I click on 2 of them in quick succession, they are sent fine also. 3. However, if I click on only ONE QTC, like for a single repeat, it hangs in diddle after the serial number is sent. This is true with both Soundboard FSK and MMTTY (FSK MODE) modems. Any ideas please? Tnx!
