Paul, I have noticed this same behavior with my K2+DSP, but I haven't been able to duplicate on my K3 (maybe because the DSP parameters are not as easily configurable). The ability to pull a signal out of the noise with the K2+DSP is profound, but I profess I have not used a TS480 either.

The cable model number on the "cables" page for each interface is a link to the schematic. As far as the USB Interface II and the K3, you can ignore the audio functions as the USB II only provides isolation transformers and the K3's line out is already isolated. With the K3 and USB II you might as well connect the 3.5mm cables directly between the computer and Line In/Line Out. 73, ...

Thanks Joe... After looking it over more, it seems like the only advantage is it will operate from one USB port versus two Serial Ports... Which may be useful with a laptop or new destop w/o serial ports.

Julius, I did not have Interface II. I have chosen Microkeyer II instead
because it has got built in sound card and Winkeyer. I use both. I originally ordered the cable for IC7000 and then built my own cable for K3. Anyway please note that it is pretty difficult to make the cable of such a quality that Microham supplies. All the schematics for all the cable is available from MicroHam. In Microkeyer it is not enough to change connectors. You have to set jumpers inside DB37 in the correct way. I suspect it should be similar with Interface II. These jumpers basically tell the device what radio you are going to connect. Different radios have different CAT specs and set of commands. 73, Igor UA9CDC ----- Original Message ----- From: "Julius Fazekas n2wn" <[hidden email]> To: <[hidden email]> Sent: Wednesday, June 17, 2009 8:24 PM Subject: Re: [Elecraft] K3 vs. Icom IC-7600 > > I picked up a microham USB Interface II this past weekend.

Most vendors nowadays support at most two generations of Windows. I've just reached the point where I've upgraded to XP because more and more stuff won't run on '98 and more and more hardware doesn't have drivers for it. In the process it looks like I have lost a sound card and a scanner, because they are considered obsolete models by their vendors and do not have XP drivers. (They do have Linux drivers, and Linux support is potentially indefinite, as long as parallel ports and PCI last.) Although the sound card is more recent than the SB Pro, even though that established an interface standard, it looks like that isn't supported. You have to go back to serial ports and Epson 9 pin printers to find standards that have survived. USB devices come into two categories, ones which can be handled by class drivers, e.g. memory sticks, and some USB sound devices, and more custom ones. The customs ones will tend to die in one or two generations of Windows. The class ones will survive longer, but USB itself will probably be superceded, and, unlike RS232, it is too complex for an individual to host it on top of the latest and greatest technology. Whilst Elecraft remain in business, under the current management, they may well be prepared to update drivers, at a price, but if they don't USB radios will rapidly become doorstops. -- David Woolley "The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio" List Guidelines <http://www.elecraft.com/elecraft_list_guidelines.htm> ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Plus there will shortly be a USB 3.0 spec. I don't know if the connectors
will be the same, or how backward compatible it will be with USB 2.0 (I assume 100%). There's a danger of linking your radio too closely to the world of PC's; the rate of technological change is incredible, and the rate of obsolescence is commensurate with that. That is something which I keep very much in mind with radios like the Flex, and the idea of PC-dominated radios in general - really, you're always potentially one Windows update away from breaking the rig. If the company goes out of business, or does not feel like supporting an X-year old, non-current version of their product, you are done. Over and out. Just my opinion. 73, Steve NN4X On Thu, Jun 18, 2009 at 5:35 PM, David Woolley (E.L) < [hidden email]> wrote: > Joe Subich, W4TV wrote: > > > > > For those who would want USB support for the K3 ... the cost > > and red tape required for Windows Certification are very > > significant for a small company. > > > > > > Also, it is an ongoing cost.

-----Original Message----- From: Steve, NN4X That is something which I keep very much in mind with radios like the Flex, and the idea of PC-dominated radios in general - really, you're always potentially one Windows update away from breaking the rig. If the company goes out of business, or does not feel like supporting an X-year old, non-current version of their product, you are done. Over and out. -------------------------- I'd not thought about that but I think Steve is right on. A hardware or self contained rig will continue to work even if the company goes out of business or the rest of the world around the rig changes. Once it works, it always works. If the company goes away, the rig still works. The true SW radios (Flex, others?) depend on having the right version of Windows. When Windows changes and the flex SW doesn't work, your radio doesn't work. So to keep your old Flex running, you have to keep your old PC running as well. No upgrades. And good luck if your 8 or 10 yr old PC needs to have a part replaced. Now, think about the value of a 20 year old Flex radio. Compare that to the value of a 20 Yr old Drake or Heathkit rig. One is a rig you can put on the air, the other is probably a doorstop. - Keith N1AS - - K3 711 - ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I kinda felt that the K3 had a raspy and brash sound until recently when
I installed a filter that Elecraft has been testing. This filter helped my K3 sound a lot more like my K1 and for that I'm quite happy. You guys will also be happy if Elecraft kicks the board out as it allows you to melt some solder inside. ~Brett On Sun, 2009-04-05 at 14:20 +0100, Dave G4AON wrote: > There's an interesting IC-7600 review on eHam where "RFEXPERT" is > comparing his new IC-7600 with his K3. > > http://www.eham.net/reviews/detail/7775 > > 73 Dave, G4AON > K3/100 #80 > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

What would be slick is to see the I/O board with a PCM2902 on it as
well. Most operating systems have drivers for this IC and it just shows up as a sound card. So if a 2902 and a FTDIChip were plopped down and tied to a hub you could have the radio when plugged in show up on most computers (windows, linux and mac at least) as an RS232 port and a sound card. Then just point your digital software at the newly installed sound card and all of the line level audio connections are made for you. ~Brett On Tue, 2009-06-16 at 11:19 -0700, wayne burdick wrote: > Dan Copeland wrote: > > > ....can't understand why the K3 didn't > > come with a USB port instead of the outdated com port. > > The KIO3's digital I/O module could be replaced with one that has USB > rather than RS232 -- or better yet, both.

You can do a lot more than 38400 over RS232 as well so even if the K3
goes to USB you're probably not going to see more than 38400 being piped over. But yes audio could be added via another USB endpoint.
