Hello, You will be reading this because there is a problem connection Ham Radio Deluxe (HRD) to your radio. Portmon is an excellent program which will record all COM port information which you can send to simon@hb9drv.ch for analysis. The Steps: [1] Unpack this zip file into the folder of your choice. [2] Close any programs connected to your radio. [3] Start Portmon.exe [4] Make sure these options are set: Menu Option State / Comment ---------------------------------------- Options Show Time ON Options Show HEX ON if ICOM, Yaesu or TenTec OFF if Elecraft, Kenwood. ON if you are not sure (I read hex) :-) Options Clock Time OFF Computer - select your local computer Capture Ports The COM port where you have connected the interface to your radio, select only one COM port to avoid confusion. Capture Capture Events ON [5] Start HRD, connect to your radio. You will see output similar to Boris.log in this zip file. [6] Let HRD run for about 60 seconds while you perform your tests. [7] Stop HRD (File: Disconnect). [8] In Portmon set the Capture: Capture Events option to OFF. [9] Save the logfile to disk, put into a zip file if possible and send to simon@hb9drv.ch all I'll be able to analyse this. Thanks for your help, Simon Brown HB9DRV
