Re: [Elecraft] KRC2 /K3
On 9/5/2013 1:09 PM, Pfizenmayer wrote: OR - is it worth changing to the RS232 bus and using the BCD data from the K3 ? Looking at the KRC2 schematic , it looks like the microprocessor is still in the act with the RS232 inputs going thru it . But I have filtered RS232 data lines with Ferroxcube VK400 2 1/2 turn hi mu ferrite chokes and 0.001's at least on PTT and KEY lines with no problems. I inherited a pair of KRC2s from N6RNO as part of the bandpass filter kit for our CQP multi-op setup. As built, they are FULL of Pin One Problems, and they are completely unshielded (thanks to paint between the chassis and things that are intended to contact it, and paint between sections of the enclosure that should make contact but do not). It took me an hour or two on each unit to clean up the mess. Most "RF in the shack" is the result of Pin One Problems. If your antennas are close to your shack, they will put RF in your shack, but our equipment SHOULD be designed to reject it. Pin One Problems are an open door into equipment for hum, buzz, and RFI. Lots of detailed stuff about Pin One Problems on my website. http://k9yc.com/RFI-Ham.pdf and http://k9yc.com/publish.htm One very useful piece of information is that all that is required to get band data from a K3 to a KRC2 is a single run of coax to connect the AUX BUS. Pin One Problems can be avoided by connecting the coax shield at both ends to the SHELL of the DB-connectors. BUT -- in the KRC2, the shells of the DB-connectors are insulated from the chassis, so that's one of the messes that you must clean up. Both the K3 and KRC2 are designed to be "universal" in their AUX interfaces, so they provide BCD data on other pins in the DB15 for use with other radios and other interface equipment. Another idea Hank -- if you're using an RS232 interface, see my notes about using CAT5 cable to build your own RS232 cable. Twisted pair provides strong rejection of hum, buzz, and RFI. Use one pair for each signalling circuit, with the solid color going to the high side pins (2, 3, 4, 7) and the striped conductors twisted together and connected to the DB9 shell. 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

BTW for a true "stealth" ham rig, you'd think a KX1, KX3.. or ATS-3 or 4.. or a true "spy set" would be what a real spy might use. But maybe Ford was not playing a spy, so a boat anchor was OK plot- wise. Doesn't look like we will get the see the movie, unless they release it on DVD and it shows up in a dollar store. 73 de Ray K2ULR KX3 #211 __ 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
[Elecraft] Off-topic - 60m operation
Hello Group, It is off-topic but I need your expertise. I will soon represent the local amateur radio sector to discuss with local telecommunication authority about the possibility of 60m operation in Hong Kong. I understand that both US and UK have allocation in 60m so that some of the group members have operation experience in this band specturm. I would be grateful if you could advise me the following: 1. In most of the circumstances (even at current bad band condition), what will be normal communication range? 500km? 2. Comparing with 40m, what is the advantage of using 60m? 3. Is 60m often used for ARES purposes? If yes, what is the rationale behind? Currently, there is no allocation of 60m in Hong Kong for amateur service as well as the Region 3. Please reply off-the-list and thank you for your help in advance.

Re: [Elecraft] KX3 - CW - What's This Sound?
I got some more suggestions. One of them was to adjust the CW sidetone pitch. That in combination with AF gain seems to be helping. Apparently, this is a problem with my hearing and not the audio output. I guess I was around too much artillary and shot too many rounds down an M-16 when I was in the Marines. ;) On the K3, 570 Hz is a comfortable CW sidetone pitch for me. At least I have not noticed the same audio effect on it that I notice on the KX3. Playing around with a combination of CW sidetone pitch and AF gain, I have been able to almost eliminate the noise I'm hearing. Thanks for all the help with this. BTW, while testing on the air, I met all kinds of folks. It's really cool with folks trying to help out. It seems most hams want to try and help out with problems (real or perceived) that affect someone's equipment. 73, Joel - W4JBB __ 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
Re: [Elecraft] K3 NR needs improvement
Yes, The NR needs improvement (at least on SSB) and the notch should be inside the AGC loop. It has been said so many times before. I know there are people who use the K3/IF - softrock/lp-pan - comuterSDR-software combo in same cases instead of the K3 SDR. H, The NB's (DSP and hardware) both work as I would expect. In de upcoming TN2MS DXpedition I will use the the K3-NR on 160/80 CW. That is where it helps me against the fatigue of a whole night on those bands. 73 Arie PA3A __ 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
[Elecraft] K3 WTB KPA3
Hi All. I'd like to purchase a KPA3 100W PA for my K3. A recent PA would be preferred. Perhaps best to keep responses off-list, so please email me at dave at g3tjp dot com. Many thanks and 73.

Re: [Elecraft] K3: Stealth High-End Radio
It always amazes me, how these high flying film people can get it so wrong. Whenever Ham radio is featured. It's either too corny for words or, as noted previously totally inappropriate equipment, eg receivers being used as transmitters and tuning the RX with the PA tune etc etc, not to mention absurd operating practices and language. Surely in this high tech film industry there are switched on people who could advise and provide a more realistic portrail of Amateur radio. Ho Hum, then I guess it's only important to us wierdo Radio Hams !! 73 F5VJC On 6 September 2013 10:24, AD6XY wrote: > That's Spectre (SPecial Executive for Counter-intelligence, Terrorism, > Revenge and Extortion) for you - no tolerance of incompetence. > > Anyone know what "The Lad Himself" is screwing an 19DS/87B into in The > Radio > Ham?

Re: [Elecraft] K3: Stealth High-End Radio
That's Spectre (SPecial Executive for Counter-intelligence, Terrorism, Revenge and Extortion) for you - no tolerance of incompetence. Anyone know what "The Lad Himself" is screwing an 19DS/87B into in The Radio Ham? There is a nice collection of amateur radio equipment in that episode. IMO, with the large dial and amber glowing display, the K3 looks a lot more like what most people would consider as a radio than the latest behemoths from the big three manufacturers.

Re: [Elecraft] KRC2 /K3
Hello Hank I sympathize with these difficult issues - the KRC2 is out of date and its about time it was replaced but at least it has always been reliable. I have one and it has never suffered from RF getting into it. Sorry if the below is stating what is already obvious to you. This may be a symptom of an RF in the shack problem. The 1ft line should not be a problem and as long as it is screened additional filtering should not help. Using RS232 may cure the symptoms but not the cause and your own BCD interface likewise. If it is an RF getting into the system problem, how might that be happening? A good way to check if it really is RF in the shack is to ask yourself if you have issues with lots of noise on the bands from the shack computer. As antennas are reciprocal, if you have significant coupling of RF back you will also have coupling of noise in. Obviously with 1500W the antennas will have to be a long way away from the operating position (for safety if nothing else) so we can probably rule out this being due to direct radiation from the antenna. I assume you have remote antennas and the array solution switch somewhere remote with a long feeder back to the shack. Maybe at the base of a tower. Could RF be getting back on the control lines from the remote switch? Are the control lines screened? Are they running close to the feeder. Putting ferrite on the switch control lines may help. Ditto the feeder. Burying the feeder helps a lot but isn't always practical. One of the worst configurations for this problem is a feeder on a catenary because it will pick up like an antenna, especially if you have an effective RF choke at the antenna end. If you have that arrangement, ferrites are the answer - plus a good short connection to your RF ground where the cable enters the house. The other possibility is you are using several feeders via the switch with an ATU in the shack. That's a problem because you will potentially have a bad match on the feeder in use, almost certainly a bad match on the feeders not in use which will result in the pickup from all the feeders merging at the switch. So, if the remote switch is actually in the shack I would investigate if you can improve the grounding and maybe move it somewhere else - like right next to the ground stake.
