Re: KX-1 BC interference on 20m

Hi Geoff
Well, I left out perhaps the most important info in that I don't have the problem on the same antenna with either the K2 or K3. I have mentioned the knock that the KX-1 received. I have subsequently found that the knock has broken the soldered joints holding both earth pins of the bnc socket- looking at them I'm pretty sure they were dry joints anyway. Having resoldered them, most of the BC qrm has gone, but not all. I have the same effect both here in the UK and in Portugal and France, so it's not a nearby fence in this case :-)) I'm sure that I did not experience the problem when I first had the radio and I am wondering if there are further joints which have been disturbed- my son caught the coax with his legs as he walked past my tent and the radio flew off the table really very quickly! I was pleased to find that it still worked. 73 Stephen G4SJP On 25/08/2008 19:21, "Geoffrey Mackenzie-Kennedy" <[hidden email]> wrote: > My thought is that the problem was caused by one or more of the natural > spurious responses of the KX-1's receiver, not by some harmonic or spur > generated by the BC transmitters themselves.

If you notice, the USB port is fixed there. The whole communications
interface area of the K3 can be update, modified, and changed as the rig and firmware grows. Elecraft chose the RS232, as a port that so many folks have used in the past. If you listen to hams (like on this list) think about how many are resistant to change. If they had come out with USB and no serial there would have been a cry from the masses of DOS/Win95/OS2/WinME/Win98 users that they could not use their serial ports. Don't get me wrong, I find USB/Serial adapters annoying, but mine has worked great. I get the Belkin ones that Staples sells, and everything has worked fine for me. I would rather have a USB interface, and possibly an Ethernet interface. But I am very happy to know that I have a rig that is getting firmware updates, and the hardware was developed in such a way, that it has the ability to grow and change, as the technology does.

I suspect the Elecraft would cooperate if someone were to endeavor to
provide a replacement KIO3 module with USB substituted for the serial connection, as long as it looked like a serial port to the K3 and to the computer OS (for software compatibility). In fact, you could probably hack the existing KIO3 module relatively easily. I'm actually considering that (for a different reason), myself, but time for such projects is in short supply. In the meantime, what we have is flexible and easy to use. 73, doug Date: Mon, 25 Aug 2008 11:12:12 -0700 (PDT) From: Lee Buller <[hidden email]> I like what Julian said here and I think he is spot on. I do not think it would take much for the wizards at Elecraft to redesign the KIO3 to include both...RS232 and a USB port. users could swap out one for the other and you have USB port. That is so cool about the K3 and its modular design. Again, the whole issues of drivers come up, but I am sure Elecraft would keep up with it all. But that is another expense to redesign the unit and keep up with all the programming of the USB drivers. RS-232 is not going away anytime soon, but you are hard pressed to find these ports on new systems...laptops in specific. As long as the USB to Serial cables are available, I think Serial devices will be around for quite awhile. The technology is proven...although old ... but very proven.

By using a standard RS-232 port Elecraft has provided greater flexibility. If they had provided a USB port then everyone is stuck with it. A serial port can be interfaced to USB using a readily available and inexpensive adapter, or, as has been pointed out, by installing a PCI serial card in an expansion slot. A USB device can only be interfaced to a PC that has a USB port and drivers for that particular device. Of course, Icom will ensure that the drivers are available today to connect the thing to Windows. But drivers may not be available for other platforms (as was the case with the RigExpert interface I sold because I could not use it under Linux) and they may not be available at all in 25 years time by any OS which is not an unreasonable time for someone to still be using a radio (even if not the original owner.) Whereas you can be pretty damn sure that RS-232 ports will still be around, and there will be adapters to interface them to whatever type of peripheral connector is popular at that time. I have grown resigned to the idea of throwing away perfectly serviceable computer peripherals only a few years old because drivers are no longer available but that is not something I want to do with a $4000 radio. _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

If I was asked to vote for an alternative interface I'd vote for Ethernet. But in that case I'd also like to have streaming audio in and out of it. Being able to remote control a radio is not a lot of use unless you can get audio in and out as well, and if you need a computer to handle that then you might as well use it also to handle the CAT commands.

In reply to this post by Greg - AB7R
HI Greg and all,
Just to clarify at bit, I wouldn't compare the 7600 as a IC-746 less 2m. The 746 series rigs never had a "real time" bandscope, but the IC-756 Pro 3 and the 7700 are about as real as it gets. If I was going to compare the 7600, I would compare it to an enhanced Pro 3 or a 100 watt 7700. However that's just my take on it. The larger displays also serve as nice platforms for plain English menus (I've always wonder what they do in other countries?) and make nicer displays for PSK and RTTY if you are not using a computer. I love great radios, but I would rather I have great antennas (I don't) and be a great op (sorry to say I am not!). Now time to fire up the K3 and make some contacts anyway. :-) 73 de jay/w5jay.. >>I couldn't agree more! This is an IC-746 with a few new features and less >>2M. So what? It may be nice for the casual operator not concerned with DXing or contesting and cannot afford their 7700. I don't know first hand, but I understand the scopes on this and the 7700 are not real time. I just don't see the usefullness if it's not. Competition for the K3? I think not. ------------------------- 73, Greg - AB7R Whidbey Island WA NA-065 On Mon Aug 25 4:38 , "DOUGLAS ZWIEBEL" sent: >http://www.ab4oj.com/icom/ic7600/main.html > >not in my opinion! > >de Doug KR2Q >_______________________________________________ >Elecraft mailing list >Post to: [hidden email] >You must be a subscriber to post to the list. >Subscriber Info (Addr.

Hi Stephen,
It might help if you could identify the SW stations you're hearing, and find out what frequency they're on. What you could be hearing is a very strong signal on the receiver's image frequency, and the only thing you could do would be to add more selectivity to the front end to attenuate the signal on the image frequency. Ask Elecraft, they would know. 73, ed - k9ew www.k9ew.us\ _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

My thoughts exactly, although there are VCP drivers for the FT232R
available for W98/SE/ME, if "unsupported". I've just been messing about with computers (I did way to much back when, and it's not fun any more) and drivers are being painful, as usual. I resent facing scrapping a perfectly good bit of hardware because of the upgrade or else mentality. Elecraft has done exactly the right thing. 73, doug From: "Joe Subich, W4TV" <[hidden email]> Date: Mon, 25 Aug 2008 18:12:16 -0400 > In fact, you could probably hack the existing KIO3 module > relatively easily.

But with what we have (an RS232 port) and nicely isolated line level
in/outs you can have all of that capability and you don't have all of that noise generating equipment inside the box with your sub microvolt sensitive receiver.

Re: KX-1 BC interference on 20m

In reply to this post by Ed - K9EW
Stephen and Ed,
I was thinking along those same lines. On 20 meters, the KX1 LO signal is below the RF signal, so a strong BC station in the 4.1 to 4.3 MHz range could push itself through and be heard on the upper end of the 20 meter band. If you have no stations on that part of the spectrum, you can likely reject the assumption of an image response. The KX1 design faced many challenges in order to stuff all that performance in a small space, so the design is a bit of a compromise. The front end suffers from responses in the presence of strong RF energy just like any other Gilbert cell mixer connected in the receiver front end (with no RF amp stage for isolation). My understanding is that the Gilbert cell mixer can generate 'funny stuff' in the presence of strong RF energy fields like might be found in Europe - in reading EMRFD, I find that Wes Hayward does not even recommend the gilbert cell mixer for use in receivers that will be used on the Eastern side of the US for this very reason. In addition, the DDS does have some spurs that can be mysterious - if the offending signal tunes more quickly than normal signals, you are likely hearing the result of one of the DDS spurs. The KX1 is a good design, but it just is not perfect in all ways. You may be hearing the result of one of these imperfections - OTOH, you *could* have a problem there. Comparison with another KX1 under the same circumstances is one way of telling whether a problem exists or it is just one of those design compromise situations. 73, Don W3FPR Ed - K9EW wrote: > Hi Stephen, > > It might help if you could identify the SW stations you're hearing, > and find out what frequency they're on.

Good point. I am often amazed with concerns about birdies. I have
several networks, and multiple computers and other equipment within feet of the K3. I have birdies all over the place. But none of them have gotten in the way when I was operating.

Being the not-so-proud owner of several pieces of once expensive but
now useless junk, I'm somewhat sensitive to future issues that might prevent me from using hardware I purchased. In other words, the "DON'T upgrade or else" mentality. With the K3, the only potential weak link I see is the K3UpdateUtility. Will it still run on Windows 2018, Mac OS XII 12.2, or Ubuntu Zesty Zebra? If I find a "Brand new in box K3 SN 2000" on eBay 10 years from now, will I be able to load firmware version 2.32 on it? I totally understand that manufacturers can't support their devices forever across all possible platforms. But I'd feel better about my purchase if there was a public spec that detailed how to upload firmware files. Next best thing would be if source code to the K3 Update Utility(s) were available. 73 -- Joe On Aug 25, 2008, at 3:26 PM, Doug Faunt N6TQS +1-510-655-8604 wrote: [snip] > I resent facing > scrapping a perfectly good bit of hardware because of the upgrade or > else mentality. > > Elecraft has done exactly the right thing. > > 73, doug > _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I'd bet dollars to donuts that if this board was redesigned that what
would happen is that an FTDI chip (or similar) would be dropped in and put onto a board that replaced the KIO3. Guess what.... The USB to UART converters are identical to that solution. The only difference would be that you don't have the RS232 level signals that have to go through the RS232 chip that is in the KIO3 right now... It doesn't really change much. Granted it puts every one on a level playing field as to what USB chip is used but buying the USB to UART converter from Elecraft does just that as well.

I do not think it would take much for the wizards at Elecraft to redesign the KIO3 to include both...RS232 and a USB port. users could swap out one for the other and you have USB port. That is so cool about the K3 and its modular design. Again, the whole issues of drivers come up, but I am sure Elecraft would keep up with it all.

If (and I mean *IF*) Elecraft is still updating the K3 firmware in 2018 then I guess there will be an updated update utility. If not then barring your scenario of finding a never-updated K3 on eBay, I doubt if there'd be much need for it. I do agree though that making the source code available or publishing a spec would be a no-cost way to secure user concerns about obsolescence. I recently wrote to the developers of the RigExpert AA-200 antenna analyzer asking for information about the communications protocol for that. No response. The device comes with software for Windows only (and it doesn't run under Wine, either.) I would like to safeguard my investment in it, but without their help I guess I'm going to have to try to figure it out for myself. Anyone know of a bit of software that will print out a trace of everything that's sent and received through a COM port? (It might also help me find out why Fldigi RigCAT support doesn't work reliably with the K3 under Windows.)
