We need them, but why oh why have computer manufacturers stopped fitting normal serial com ports on new computers ? Instead we now have to rely on a software alternative “Virtual com port”.
I have been spending a lot of time running DM780 over the last five days and it has been running flawlessly yesterday I called a station and it locked in transmit – not exactly the ideal situation, I could not see what had happened and HRD would not close down as I had switched the radio off manually – I re-started HRD/DM780 etc… having re-booted the system and called CQ – a station called me and I promptly replied and it happened again Grrrr !
Now I noticed that HRD had lost it’s connection to the radio and trying to re-connect it failed, I even tried other combinations of RTS / DTE settings to no avail so I thought maybe the driver for FTDI devices had gone bad on me so downloaded an update – which could be rolled back if necessary if it didn't work out, incidentally it designated another com port number as well, this was installed ok so tried again (this was all taking time instead of filling the log) Grrr !
I called CQ and it bombed again Grrrrr! (What else had I done recently to upset the system) ? Oh yes last Thursday I installed the latest HRD update – build 28xx something or other, luckily I kept the previous version so I could drop it back in place and see if that helps NO it does’nt ! Grrrr.
Looking back – I used version 4.1 of HRD on my old laptop for ages with my signalink (using a proper serial com port connection) with the FT817 then upgraded later to HRD v5.00 xxxxBeta without any problems at all – in fact HRD has been rock solid but this USB device has started playing up – I was suspecting the interface but that’s working ok – I am beginning to wonder if there’s a little bit of Rf getting into the loop ! (Will fit some ferrite chokes on the cabling) next – interested to hear if anyone else has had USB CAT connection trouble.
