KX4Z Turns out it seems to be the PACTOR modem that is bad. Replaced it with one of my backups which N0IA Bud sold me for a SONG just to help me get going --- and it works!!! Two days now and no further "pactor error detected and logged" messages.... So I guess will need some service on the one I had been using..... Bud's legacy lives on!!
KX4Z -- recent onset of problems keeping PACTOR modem connected seemed related to Prolific USB->serial converter, in service for many months. Something changed? Purchased/replaced with FTDI based converter and so far seems to be working better. Just had 45K transferred by user over PACTOR.
KX4Z -- last 2 weeks intermittent "port denied" on USB --> Pactor III modem.... suspect some problem with USB to serial converter, have ordered new one. Computer runs Windows 10, has generally worked flawlessly for months, now this problem. No problem at all with older VISTA computer that has USB to Pactor DRAGON modem in NCSHARES network.
