Re: [Dx4win] USV to CIV
No thanks Kostas. It is fairly obvious from your response and others I have corresponded with at length that these cheap Chinese interfaces sold on eBay do NOT work properly... they are introducing errors and relying on error correction in the programs to make them work after a fashion.

But i have not tried the solutions. Maybe i can find my supplier if you are interesting.

DX4WIN doesn't read all of the response string from the rig when it's checking what mode is currently set. When the next command is sent, DX4WIN sees the leftover garbage and recovers. The lack of buffering in the cheap interfaces means that this leftover garbage isn't reliably read and confuses the next command (which is what reads the VFO). All that I do is to fix the command definition to read the entire response. You can see this for yourself using your current interface: File/Databases/Radios, select the Test tab, then click Read a few times. Notice that every time DX4WIN complains about garbage ignored or something like that. Fixing this bug makes the cheap interface 100% reliable, at least for me. The non-USB interface still works fine as well (even though it didn't require the fix). 73, -Rick -- Rick Murphy, CISSP-ISSAP, K1MU/4, Annandale VA USA __ Dx4win mailing list Home: http://mailman.qth.net/mailman/listinfo/dx4win Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Dx4win@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Are there any that work other than the Rigtalk which is a bit pricey at $60. My USB CI-V adapter was an inexpensive eBay purchase that worked sort of OK for most DX4WIN operations (clicking onto a spot reliably set the rig to the spot freq) but didn't reliably read the rig's frequency. I've discovered that this is due to an error in the rig files that's pretty easily fixed. While the current DX4WIN operation doesn't follow the CI-V specification, there's enough ambiguity in that spec that my change could break some CI-V rigs. If you can't reliably read the VFO off of your ICOM, let me know and I'll tell you how to fix it. Actually, if your CI-V rig works now, and you're willing to try the fix, let me know and I'll explain. I don't think the fix will break anyone but will allow less robust adapters to work right. 73, -Rick -- Rick Murphy, CISSP-ISSAP, K1MU/4, Annandale VA USA __ Dx4win mailing list Home: http://mailman.qth.net/mailman/listinfo/dx4win Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Dx4win@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
