I brought this up a few months ago to see if anyone else was experiencing the same problem. A couple of people responded to me. So far I don't have a resolution. This appears to be a bug in DX4Win or the rig file for the Yaesu FT-950.
What has been happening is that DX4WIN, when configured to link up to a Yaesu FT-950, experiences a freezing every 3+ seconds for about 1.5+ seconds (poll rate 500 ms). This causes serious problems when attempting to run CW with the keyer interface, as well as problems with clicking on anything in DX4WIN. If I change the poll rate to 5000 ms, the period between freezes goes to about 5 seconds. And if I set poll rate to 10000 ms, the time between freezes is 10 seconds. If I am typing or even clicking on the Fkeys in the CW window, it will freeze sending (or response) every 3+ seconds for 1.5+ seconds (poll rate 500 ms). Very annoying to have my sending pause in the middle of a word! Another example where I see this is to go to the DX spots window and press the up/down arrow keys fast to move up and down the list of spots. The highlighted spot will move up the page for 3+ seconds and then pause for 1.5+ seconds. Menu action during this 1.5 second pause will freeze too. At the exact time this freeze happens, taskmanager shows CPU load of 50% on one of my computers and about 30% on another. I am running DX4Win 8.05. The main computer is a newer Dell running Windows XP SP3. I have also tried a new laptop running Windows 7. I have tried connecting using standard RS-232 connections and a USB to RS-232 adapter (FTDI chip). I have tried different CAT speeds, polling rates and comm port settings but nothing fixes it. I do not have this problem with any other radio, including a Kenwood 950-SD and Icom 706. And I never had this problem when I used my Yaesu FT-920 that I sold last summer. I have also used the same computers and FT-950 with Ham Radio Deluxe. HRD is always immediately responsive, with no problems at all. I have also used N3FJP contest software with no freezing problems. My only solution to this problem so far has been to run DX4Win with the radio stopped when I want to send CW with it. Can anybody help with this problem?
