I have found fldigi to be quite confusing to set up for CAT, the software is great but the rig control options and PTT possibilities confused me. Once I began to think about it more, it made more sense. Of course, all of this would have been less confusing if I had read the guide for beginners that is included in fldigi but heck, I never read such things!
In Fldigi a user has several options. These options include deciding whether your rig needs a separate circuit to place your rig in transmit, or whether you want the rig-in-transmit (PTT) function to be handled by CAT control, and thus a need for only one comm port to be used. Additionally, if you set a PTT option, you need to determine if it requires RTS , DTR, etc. Some rigs can do PTT via CAT control and some cannot, so this needs to be determined as part of setting up fldigi and other digital mode applications. The Kenwood 570 (and most other Kenwoods ) CAN do PTT via CAT control. So you can set Fldigi to control your rig and PTT via use of one comm port and the correct use of other comm port parameters. However , one option that Fldigi gives is the option to use HAMLIB's setting for rig control. This uses pre-programmed XML instructions to communicate with your rig. To establish preprogrammed XML for every rig that is on the market takes a lot of time. Not all rigs are fully coded for Hamlib , you will see in fldigi that some are "stable" (coded, tested, and reported to work well) and some are at "beta" or alpha level. I have found the TS2000 hamlib file to not be very reliable, in Fldigi it is marked as "beta". As recommended to this group on several occasions by Skip Teller, use of the other rig control methods in fldigi often results in better operations . Rig CAT , with a file for your radio , is usually suggested. For my Kenwood TS440 and Kenwood TS2000 I use RIG CAT or Hamlib with ANOTHER option, Hardware PTT. That requires use of a separate comm port for PTT but I find it more reliable than some of the beta/alpha rig control XML files that exists for my radios. That's the long reply to Danny. A simpler reply would be that for most Kenwoods using Fldigi do the following... Go to CONFIG/RIG CONTROL CLICK on HAMLIB Check "use hamlib" Select a comm port >From the drop-down list of rigs, choose Kenwood 570D (stable) Choose a baud rate that matches the baud rate you have set in your rig (I use 9600) many Kenwoods have 4800 as the default. Do NOT check PTT via HAMlib. Save/close. Now in Config go to Hardware PTT Select a second comm port, one that is different from the one you are set under hamlib Click on the tiny diamond next to :use separate serial port PTT" Check use RTS Initialize Save/close Andy K3UK On Fri, Nov 20, 2009 at 11:26 PM, Stelios Bounanos <digra...@enotty.net>wrote: > >
