Re: [Elecraft] Little brown truck arrived w/ my K3!
Our little border collie used to go nuts! if a brown truck came into the neighborhood. Sadly she passed in 2009 but now we have a not-little German Shepherd-mix that goes nuts if any vehicle drives down her road :-D Re: use of the K3 with computer for digital modes. I have never of heard your complaints on the K3. I have mine directly connected with RS audio cables (with 2.5mm connectors) and the K3 USB/RS232 cable for control of PTT and keying. I've no problem with hum or difficulty setting levels. I pre-set my K3 Line-in at 10. I use two different soundcards: emu0202 and Delta-44. http://www.kl7uw.com/station%20layout.htm The automatic mode shift by memory channels is very nice. I use the Frequency Memory Editor to set up my favorite digital frequencies (once) and forget. I use DATA-A for this since I am running soundcard sw on my computer (WSJT, WSPR, FLdigi). 73, Ed - KL7UW http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: dubus...@gmail.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

Definitely use some type of external sound card. In this day and age and all the admonishments to not do so, I *still* hear Windows sounds over the air when using the “default” sound card.

Re: [Elecraft] Little brown truck arrived w/ my K3!
Thanks to all for the great info, and esp. Walter and others who suggested the reading material from Jim, K9WC, I'll make that a priority to digest. I hadn't thought about the PC sounds, so given the way I operate, I'll probably opt for the external sound card. I love my PC sounds, and have custom sounds for lots of events, including the band edge alerts, and sounds from other programs that I usually have open when I operate. I'm so silly with my sounds I have a 4-port mixer here in the shack that I pipe everything into to drive a pair of old speakers. Looking forward to experiencing whatever stereo effects are offered in the K3 using that setup! (Hint: Feature request: Stereo CW where the center of the passband is in the middle, with lower freqs going left, and higher freqs going right...) ;) I started the build last night, looks like I'll be done in one or two more evenings.

Chris, A good quality external soundcard will do much better than the SignaLink (the Signalink noise floor is poor and is only a single audio channel). The K3 has galvanic isolation (transformers) built into the Line In and Line Out lines. Jim Brown K9YC has recommended a Tascam soundcard as a good and relatively inexpensive one.

Re: [Elecraft] Little brown truck arrived w/ my K3!
Hi Chris, I've been going direct for digital modes for years with my K3 and never had a problem even at legal limit. If you like your PC sounds and don't want to turn them off when you operate digital you only need a small under $10 USB audio adapter. I'm using this one: http://www.amazon.com/gp/product/B001MSS6CS/ref=oh_aui_search_detailpage?ie=UTF8psc=1 It has its own identification on the Windows sound control panel so when you set up your K3 to take sounds from your PC you just identify this device as the source. That lets you set the level independent of your normal PC sounds. I still feed audio from the K3 directly into the PC. I think there is a minor problem with this particular audio adapter as it wants to be a monaural microphone input device rather than a stereo line input device. But there are many similar devices on Amazon to choose from. 73, Mike K2MK Chris Hallinan wrote I just opened the box. Can't wait to dive in. I decided to buy the kit so I'd know how it goes together and be more comfortable with upgrades later down the road. Already saving for the P3 and then the KPA500! I've been reading the list for the past week or so, and learned much about the rig from the discussions here. From some reading, I've heard that an external interface isn't required for the digital modes? Not sure about that. Wonder what others are using for external interface for digital modes? I had a SignalLink USB at one point and it worked quite well.

Re: [Elecraft] Little brown truck arrived w/ my K3!
My computer's (MacBook Pro) sound system doesn't support bi-directional sound. I have used a SignaLink for several years now and been happy with it. I do intend to get a higher quality interface to see if I can decode weaker signals. I operated using the K3's VOX for several years. My normal way of operating is to look for signals on the P3, switch to their mode, and copy them. I got tired of having to turn VOX off in the voice modes and then back on for PC digital and built a cable which connected the VOX line from the SignaLink to the K3. Now changing modes is just switching modes on the K3 and getting the right program's window to the front on the computer. I only wish my KX3 changed between PC digital and voice modes as easily.

Re: [Elecraft] KX3 case advice
An alternative to the Pelican is a pretty decent one offered by Marlin P. Jones Associates, a surplus place out of Florida. I use one of their larger size ones for the KX3. It has pluckable foam and is a tad bit cheaper than the Pelican. No manufacturer's markings on it, but it looks like it might be a (probably Chinese) knockoff of one of the Pelican style cases. They have two sizes, 12 X 7.4 X 4.4 inches ( http://www.mpja.com/12in-X-74in-X-44in-Waterproof-Case/productinfo/18351%20BX/ ) in which the KX3 fits nicely along with a 3 amp power supply, microphone, some cables/adapters and the Elecraft key paddle for the KX3. I use their smaller one for the PX3 along with it's cables. The smaller one is 9.3 X 6.2 X 3.5 inches ( http://www.mpja.com/93in-X-62in-X-35in-Waterproof-Case/productinfo/17813%20BX/ ) with the same pluckable foam. Both cases are very water resistant if not totally waterproof like claimed and they have pressure relief valves on them for shipping via aircraft. They also have locking holes for padlocks if needed. They are quite well made out of molded ABS plastic, O ring sealed and very positive latches on the covers. usual disclamer, no interest in MPJA other than a satisfied customer.

Re: [Elecraft] Little brown truck arrived w/ my K3!
David, For data mode operation, most applications use only the left channel, but there are a few that can swap channels. I would stick with a stereo device for the most flexibility. And, if you want to use the soundcard for some other purpose (such as for SDR purposes - like the KX3 I/Q RX output), you will need both channels. In other words, more flexibility, wider bandwidth and better audio noise characteristics than the SLUSB provides. The bandwidth is not important for data mode operation, but is a real asset for SDR use. 73, Don W3FPR On 12/19/2014 10:59 AM, David Christ wrote: Memory loss here.

Ah. The light bulb just clicked on. Thanks for posting the links, Walter. Great write-up, Jim. Just finished reading it. I don't need anything related to rig control if I choose vox operation, and guess what? I'm an amateur musician and I have at least 2 audio interfaces in the house. Of course, they are overkill (one is an old Edirol FA-101 with 8 inputs and outputs, and one is a very nice Steinberg UR-28M. Both are way more than I need for digital modes.)

I’ll go beyond this. CocoaModem allows for decoding two streams simultaneously. I feed the main receiver to the left channel, and the K3’s sub receiver to the right. Of course only one channel can be used for transmit since Wayne hasn’t developer a sub transmitter yet. ;-) Other digital apps provide similar services that take advantage of separate audio feeds from the radio. There are other uses - during a contest I will also feed the output of each receiver to be recorded on the computer. This allows me to replay some of the contest if I really get bored (makes good CW practice as well), and makes the disk vendors happier when I need more storage for all the audio files… Note that if you want to play with CW Skimmer having high bandwidth is a huge advantage. The SLUSB has a relatively narrow bandwidth coded which means narrow band of frequencies will be decoded. Wide band interfaces will allow a much wider swath of frequencies to be decoded with Skimmer and similar software. This will be limited by the platform hardware and USB Audio drivers in play. The Mac audio, for example limits bandwidth to relatively narrow widths (96KHz as I recall), while Windows allows double that. I do not know if Windows running on VMware Fusion on the Mac will allow wider bandwidths from the audio interface, but my suspicion is that it will since Fusion provides its own USB drivers. - Jack B, W6FB On Dec 19, 2014, at 8:12 AM, Don Wilhelm w3...@embarqmail.com wrote: David, For data mode operation, most applications use only the left channel, but there are a few that can swap channels. I would stick with a stereo device for the most flexibility. And, if you want to use the soundcard for some other purpose (such as for SDR purposes - like the KX3 I/Q RX output), you will need both channels. In other words, more flexibility, wider bandwidth and better audio noise characteristics than the SLUSB provides. The bandwidth is not important for data mode operation, but is a real asset for SDR use. 73, Don W3FPR On 12/19/2014 10:59 AM, David Christ wrote: Memory loss here.

Re: [Elecraft] Auto antenna select
Yes, I use my KPA500/KAT500 pair remotely. The driver is a K3, so I don't need RF-sensed band and antenna switching, but it should work fine with a non-K3 driver. I rely mainly on antenna switching external to the KAT, but its three antenna ports are adequate for many stations without the added complexity of external switching. For remote control, I recommend KPA500 Remote and KAT500 Remote, available on the Elecraft Web site. They provide functionally complete and graphically attractive on-screen interfaces. Although they can be used locally at the radio site, they also support a client-server mode in which the server runs at the radio site and the client runs at the control site. That requires a computer at both sites, of course. If you don't believe in having a computer active at the radio site, you can also run them in local mode at the control site only, using remote serial ports at the radio site. Your idea of pre-programming the KAT before operating remotely is a good one. I recommend using MAN mode after that. Relying on AUTO mode makes me nervous, especially when I'm not present to hear the relays clanking.

Re: [Elecraft] Little brown truck arrived w/ my K3!
Me too. I had a Signalink. With the K3 I found no difference between it and the built-in sound of my Lenovo T400 laptop, which is my current system. At K9YC's suggestion I acquired a Tascam US-100. While it worked fine, there was no noticeable difference in performance on my modes of choice, RTTY and PSK. Perhaps on so called lower noise modes like JT65 there would be some difference: I can't say. Personally, I think we're at the mercy of the quality of the line out on the K3. VOX works fine, you don't need any more complex switching. The hand-wringing over Windows sounds when using an internal sound card is unwarranted in my opinion. Turn the things off and stop worrying about it. If you're a total klutz you can have Windows sounds on your external card too. Wes N7WS 242 countries worked on RTTY using the K3.

Re: [Elecraft] K2/100?
I run my K2 from a 4S1P LiFePO4 pack. I ultimately sold my KPA100 and KAT100, I use the K2 QRP-ish in field activities and it is indeed a hassle. A warning to anyone who does swap the tops: There are two 2-wire Molex connectors from the KAT2 to the K2 RF board. One feeds RF to the tuner, the other 12 VDC. The cable lengths from the KAT2 are such that either cable will reach to either socket on the RF board. The two connectors are identical. If they are exchanged, the shield on the coax feeding RF to the KAT2 ends up on the 12 VDC pin.

Re: [Elecraft] K3/KPA500/KAT500 SWR problem
From the discussion that you referred to, I would recommend the use of thick copper braid to bond the grounds of your equipment together in order to reduce grounding problems. This is far better than using a copper bar or a single point ground in a star pattern. Now just what problem are you trying to resolve?
