[Elecraft] wanted: KAT3 Internal ATU for K3
Hi everyone, I am interested in purchasing a KAT3 internal ATU for my K3 and I was wondering if anyone had one available as a result of an upgrade that they are interested in selling. Of course, I will pay the postage costs and if payment via Paypal is ok I will cover any Paypal fee's too. Many thanks in advance, Jeff Cochrane - VK4XA (Use mycall at arrl.net for emails off list please.) - Jeff Cochrane - VK4XA Innisfail, QLD, Australia.

Re: [Elecraft] K3 Utility questions
Gary, I also had a look around for control software - but could find nothing I really liked (There re some great programs out there) - but either too complex or not focused on what I want. So…. Write your own ! I know it sounds daunting - but the K3 has an excellent programming document - and the K3 Utility gives you a test bed to try out your commands (I would suggest a degree of caution) - once you have that done - it is simply a matter of an interface - which can be as complex or as simple as you want. Assuming you do not want to write your own - but wish to use multiple programs at the same time - then…. Depending upon the port connection mechanism you are using - will depend if the port is available for other devices to use. Most software opens a device similar to a file - i.e. in exclusive mode. Thus blocking other programs from using that port. However - there are options…. Mac: the Mac seems quite happy with the /dev/CU-x to allow multiple ports Windows: I think on Windows you could look for a virtual port driver - and gain access to the “real” port using virtual ports. I did this years ago for sharing GPS Receivers amongst programs. Linux: you should use a Daemon (a Central process that listens to many clients who wish to talk to the Device). The Linux mechanism is far superior (Opps maybe I am a little biased, for it could be implemented as a service in Windows also - its just almost no Windows programmer ever does this) - but it does add another layer of complexity to the whole control process. The Daemon/detached process mechanism is best/easiest used using ricgtld (Linux) - I do see people using it for Windows also - but I have no experience on that.

[Elecraft] OT: Windows 10 observations
I have an HP desktop from Staples that started out with Windows 7 Home Office and an HP laptop ... also from Staples ... with Windows 7. Both have Norton anti-virus protection that updates nightly, DX4WIN logging programs, and N1MM+ contest loggers. They are both set up with the utilities to do updates of the K3, P3, KPA500, KAT500, KX3, PX3, KXPA100, etc. Both have 4-port USB hubs, photo editing programs and other assorted devices hooked up. I use MS Excel for coordinating Montana's VHF and UHF repeaters. The program is "busy" with about 1200 lines of data. Both (automatically) updated to Windows 10 a few weeks ago. They are connected 24/7 to the Internet via a secured router and CenturyLink DSL and spend several hours prowling on line each night. Most likely due to Century Link and Norton I seldom get SPAM. The point of all the above ... it all works and doesn't quit. I know very little about computers, but I'm happy with Windows 10! 73 K0PP __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] OT: Mobile operation "bible"
Actually Willis, there is no additional tuner. Just the motor in the antenna and a single base matching coil. I have put in a 15 turn airdux coil and use taps to set the best for 80 and up.

Re: [Elecraft] Rerouting the KRX3 AUX Input from the Rear BNC to the KAT3
Don, I have my sub receiver connected to the AUX input, and it still works just fine with diversity receive. The way you do is connect your receive only antenna to the RX in BNC on the back of the K3, then run a short piece of coax with male BNC connectors on each in between the RX OUT and the AUX input. Not sure why this method has not been mentioned in the manual. I have being doing this since I purchased my original K3. I use either Beverages, or the Hi Z 8 now; but am in the process of erecting a SAL 30 fro Array Solutions. That will give me three different choices for receive antennas.

[Elecraft] K3 Utility questions
I'm starting to explore other options with different software and my K3s. My main interest is in being able to send CW, RTTY and it would be a nice plus to send from the voice memories when calling in a pileup and not have to keep hitting the function button every time I put out my call. Seeing as I have the K3 Utility already working, I have found the terminal seems to work well for the immediate needs on CW. I do though have to run it separately from my logging program because the only port that is available is #8 and that is dedicated to the K3 and the logging program takes ownership of it. Once I make a contact I have to shut off the utility and load the program to get it logged. Then if I want to use the terminal I have to do it all over again. I tried to use OmniRig to run the K3/logging program and the Elecraft Utility but see no way to share the utility with it. - Is there another software to use the terminal with the K3 at the same time? Maybe another method? Right now I'm trying not to add more hardware. - Also, I tried to use the memories in the Utilities terminal for RTTY but could not get RTTY to work. I'm sure I missed something I need to change in the configuration but if so, I don't know what it is. Suggestions?

Re: [Elecraft] Rerouting the KRX3 AUX Input from the Rear BNC to the KAT3
Some models of UHF under-dash Motorola mobiles have a short (+/- 6") TMP M/M jumper cable connecting two boards. A female circuit board connector can be salvaged from the the radio for use as a end connector on the short cable, making a M/F extension for the input to the 2nd receiver. I have the ends of this extension cable and the cable from the rear BNC rear connector laid atop the 2nd receiver, making it an easy task to lift the top cover and choose the antenna being fed to the 2nd receiver's input. I'm not been able to find a source for cable-end female TMP connectors, or even a part number to order them from Motorola ... and I'm a retired two-way tech. (;-) Perhaps Elecraft parts may have them.

Thanks for very quick responses to my question - I'm overwhelmed! I'll remove the top cover and start right away! I have two antennas, and no special receive antenna, and the two antennas are connected to ANT1 and ANT2 all the time.

Re: [Elecraft] OT: Mobile operation "bible"
My only attempt at HF in a mobile was on my old 78 Scout Traveler (diesel). Before heading to AK I had a welder install a big front bumper with space for a winch and brush guard for front grill and head lights. Alas, I never bought the winch so had a tool box installed in its place. OK I used the 1-inch steel tubing as a clamp support for a Hustler 4BTX which I had the 80m whip option. It stuck up there a ways so was only installed when I was parked. Worked K4USA (I think the call was) from Eagle, AK to the Antarctic via 20m and 100w. The scout was a heavy rig 4500-lbs. and had a nice steel frame which probably helped. Now if you want a challenge install a 4-MHz HF Marine SSB station on a fishing boat (typ. 25-35 foot). The one's with fiberglass hulls can be a challenge. Most Marine HF used either 21-foot or 35-foot whips and had a manual tuner (In the old days vs auto-tuner now days) attached to something metallic right at the base of the antenna. Usually had a 1-inch mesh ground strap to ground and RG-8 to the radio. The manual tuners had a motorized switch to select taps in the loading coil and jumpers for the bank of fixed tuning caps. Fortunately only about six to eight channels were programmed as one could spend a hour easily trying to find the best combo of tap position and capacity. 2182-KHz was the mandatory emergency watch frequency and getting a good match was awful. 4125-KHz (4A) was the standard in AK for all the fisherman and one could hear them some times out to 800 mi at night. 100-125w was standard. On my last job I installed a Harris 1kW linear to serve as Marine HF Base on 4125 and strung a dipole at 40-foot between two Rohn-25 towers (nice to be a rich oil company!). They sold them as Satellite telephone has largely replaced HF for commercial marine. Boats still have them but little used.

Re: [Elecraft] OT: Mobile operation "bible"
I use the HiQ 4-80 with a 2' mast extender mounted on the back bumper of a F150. At the base of the antenna I have a hb box of six relays to switch in the appropriate capacitors to match the feed point impeadance and I use the Ameritron SDC-102 memory controller that does a good job of going to the saved locations but I usually have to give it a "bump" or two on 60, 80, or 160 (with aux coil I can add if I have to get on that band). As this system is "almost" seamless, and as someone else mentioned. I still stop to change bands to keep it safe.

I dont know if I want to try to power anything up in the half built state lol. I'm pretty confident in the daughter board since I checked it over after flush cutting it, etc. One of the pins got hot enough to melt the solder on the daughter board itself while I was soldering it to the RF board (my fault for holding heat onto the pad at RP3 too long) and it rocked out of place a bit before I repositioned it. It looks ok and I dont know if I dare try to get my soldering iron in there to try to "touch it up". So I'd just like to do a continuity check on that pin. And maybe the whole board while I'm at it?

Re: [Elecraft] K2 thermistor board check
LS, The most common problem with the thermistor board is a solder bridge on that board. One quick check is the voltage at U6 pin 5 which should be 1/2 of the 8 volt supply. Another check is to see if the voltage at U6 pin 1 is twice the voltage at pin 3. Those voltages will change as the VFO is changed over a 10kHz range, so check with several positions of the VFO. 73, Don W3FPR On 4/1/2016 10:41 AM, lstavenhagen wrote: Hi all, Is there a procedure where I could check the K2 thermistor board for proper operation once soldered in?

Re: [Elecraft] OT: Decoding high speed CW
Hi All, I think all the FCC code exams were plain text, not code groups--at least to my memory going back to the 50's. The reason may be obvious, in that the examiner had to check them "on the spot", and code groups would have been too difficult to check. I took the Extra Class exam in front of an FCC examiner, and I know that was plain text. I think those guys had the test material memorized, because they were checking them off pretty fast! On my test I bracketed a big section I knew was right, and showed it to the examiner. He looked at it for about 3 seconds, and said, "Yeah, you passed"! In the Army, all we used were 5 letter code groups, and those were a bearcat to check! I had that job for a while, and hated it! Sometimes the hardest part was even deciphering what had been written down. Unfortunately, penmanship was never part of the curricula!

[Elecraft] Incredible Receiver
Well the K3 is just amazing me once again. Without the benefit of anything special for antennas I have managed to hear and work VK0EK 160-10. As the saying goes, you can't work 'em if you can't hear them. The toughest was 160 (a hold your breath and focus) but there it was in the log! Ditto this morning on 10 although they were louder but lots of QSB. Thanks again Elecraft for a truly great radio!

[Elecraft] K2 thermistor board check
Hi all, Is there a procedure where I could check the K2 thermistor board for proper operation once soldered in? I just passed that step in my second K2 build, and I'm uncertain about one of the pins - it rocked out of place while I was soldering it to the RF board, but of course it's now soldered in. It's not just in there but it's IN THERE hi hi and I'd like to check it before tearing it up trying to pull it out of the board. Visual inspection still shows the makeshift pin in place, but I'd just like to do some kind of measurement or continuity at the RP3 location just to be sure.

Re: [Elecraft] OT: Mobile operation "bible"
All, The coax length doesn't matter because of the following reasons. Assuming the tuner is at the rig, there is a run of any coax to the antenna feed point, and you have a fairly high Q low band antenna that can't QSY much. With short HF mobile antennas that are high Q the reactance at the feed point when you QSY beyond 3:1 or so makes the system very lossy regardless of how low a loss or how short of coax is in there. The power accepted by the antenna under these conditions goes down the further you QSY due to the large reactance leaving the dissipated power to be burned up in the coax (and some in the imperfect antenna tuner at the rig) no matter how low loss it is or how short it is. You cannot increase the power accepted by the antenna unless you bring the feed point back closer to 50-ohms somehow through external loading of the antenna. (Even then there are other loss factors to consider such as ground loss and radiation resistance). It's kind of like a "tug of war" between two Qs. The antenna Q and the tuner Q with the coax in the middle accepting all the power. 73/72, Myron WVØH Printed on Recycled Data > On Mar 31, 2016, at 11:09 PM, Jim Brown wrote: > > Bearing in mind that in a mobile installation, coax is too short to introduce > enough loss to matter, so it's merely a matter of making the rig's output > stage happy (and running at full output). __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Short loaded antennas are, by their nature, pretty narrow band for tuning. When I still ran HF mobile, I found that a rig with an auto-tuner was a big help in extending the useful bandwidth of an antenna. If, for example, the antenna was resonant on 7075, a tuner might match it to the rig from 7000 to 7150 or even higher, whereas without the tuner I'd be limited to about half that. Bearing in mind that in a mobile installation, coax is too short to introduce enough loss to matter, so it's merely a matter of making the rig's output stage happy (and running at full output). 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to tnny...@yahoo.com __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
