The only issue at all is the digital connections between the radio, the amp and the PC. I put together a short tutorial which I think explains it better than the ACOM manual does. It is copied below. If you have any questions, feel free to contact me directly. You won't be disappointed. 73, Bill W6WRT [email protected] +++++++++++++++++++++++++++++++++++++++++++++++++++ When operating an ACOM 2000A with an Elecraft K3, there are two possible modes of frequency control. Each mode requires a different cable. When a PC is NOT connected: Use a cable like that shown in figure 7.6 of the ACOM 2000A manual. You should set the K3 AUTOINF menu option to "nor", the default. In this mode the 2000A will poll the K3 for band data and will change bands accordingly. The K3 will also send band data when you manually change bands on the K3. When a PC IS connected: Use the cable shown in figure 7.2 in the 2000A manual. You should set the K3 AUTOINF menu option to "nor", the default. Note that this cable does NOT have the TXD wire going to the ACOM 2000A, but it does have the TXD wire running between the legs of the Y connector. This cable can be either a single cable terminating in two DB-9 connectors or it can be a single cable with a "Y" adaptor connected at the DB-9 end. In either case, it must be the electrical equivalent of figure 7.2. In this mode, the ACOM 2000A gets band data information ONLY from the logging program, not from the K3. If you close the logging program, the ACOM 2000A will NOT follow band changes from the K3. You can still do band changes by sending a "dit" as explained in the ACOM 2000A manual. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
