Re: [Elecraft] A K2 Question
Irv, Yes, the K2 will serve you quite well for that type of operation. In its most basic form, it is a CW 80 through 10 meter (except 60 meters) transceiver which will go up to at least 10 watts (typically 12 to 15 watts). Options extend that to SSB (with the KSB2 option), 60 meters (K60XV option) and 160 meters (K160RX option). If you are not working with resonant antennas, the KAT2 is recommended, and you might want to consider the internal battery (KBT2 option). If you are looking for a more compact CW only transceiver, you may want to look at the K1 or even smaller, the KX1. 73, Don W3FPR On 5/9/2014 11:23 PM, Irv [K3IRV] McWherter wrote: I have seen a couple of these at friends homes, read some of 30 pages of eham.net reviews, but I have not found an extensive review on the rig as a trail radio.

[Elecraft] [KX3] HRD/DM80 and a SignaLink
Good Weekend All, Don't have easy access to search the archives, so at risk of a dup, here is a "finding" from setting up the KX3, SignaLink with the KX3 Tigertronics made cables, and DM780. HRD works flawlessly with Elecraft KXUSB here, but... Using the little paper instruction insert that came with the SL to KX3 cables from Tigertronics, it was implied that the KX3 menu entry for MicBtn was to be in PTT Up.Dn. Well, that is apparently backwards. The system behaves normally if Mic Btn is OFF, and when set as instructed in the little sheet, the outgoing data string is transmitted in your selected mode, then the SL unkeys (as it should), but the KX3 stays in transmit. When the KX3 is set as the TigerTronic folks suggest, I assume the SL vox relay was being "overruled" by the TX command by KXUSB control because tapping the XMIT button on the rig would drop the rig back into receive. With PTT set OFF, the SignaLink VOX circuit has proper control. Had me stumped for a minute.. hope this helps someone setting up in the future.

I'm using a Shure SM58, into a mic preamp, into a gate/compressor/limiter/de-esser into an EQ into a mixer into the K3's line-in. Hi Slava, A de-esser works in the 6-8 kHz range, and you need it in a studio, especially with mics like the SM58 that are sibilant, it's totally useless for ham radio. If you want to use an SM58, you can run it straight into the front panel mic input with a suitable adapter -- pin 2 of the XLR is hot, pin 3 and pin 1 get tied together and go to the connector shell. The K3 has excellent EQ and compression built in, so you've got a lot of stuff there that you don't need. The SM58 is an singer's vocal mic, it has proximity effect, which adds a lot of bass that must be equalized out. Pro mics are overkill for ham radio (in terms of cost), but if you want to use one, go for one of the EV variable-D mics -- RE10, 11, 15, 16, 18. No proximity effect, no sibilance. Another issue with trying to use a pro mic in ham radio is that ham mics have presence peaks around 3 kHz to compensate for the rolloff of the crystal filter, so you must add that with an equalizer. The TXEQ in the K3 works VERY well for that. Before W6XU turned me onto the Yahama CM500 headset, I was using an RE16 from my stash of recording mics, on an AKG boom. Worked fine, I got great reports, but the CM500 is $60, and sounds great too. So line-in is taken. I can't put a Y cable there because, correct me if i'm wrong, every time Signalink would key up - the mic would go live. So that's not an option for me. I think its a lot easier to just hit a couple of buttons and switch to the front panel mic for digital work, isn't it? And the rear mic won't go live either. As far as audio interface goes, yes, i have an E-mu 0404 USB that i can use. But signalink works just fine. No drivers to install. And it has just enough controls. If you're happy with it, use the Line In. But remember that it has a Pin One Problem, so you could run into RFI with it. I really don't see why i would need a studio quality sound card for PSK31. See my exchange with N7WS about that in this thread -- a better sound card can improve linearity at the bottom of the dynamic range. In fact, you need a decent USB sound card a LOT more than all that outboard gear. The 0404 is overkill, although nice if you want to feed a spectrum display using NaP3. The Signal Link may be good enough -- the cheap Numark and somewhat nicer Tascam certainly are. I use the CM500 plugged into the rear panel mic and headphone jacks, assign the "Headphones + Speaker" toggle to one of the PF keys. That lets you use the K3's excellent audio processing, get rid of all that outboard gear, and makes it very easy to switch from SSB to digital modes. 73, Jim K9YC Retired audio professional __ 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] Making a Signalink cable for the K3's 8-pin mic connector
You wouldn't use a Y-cable. Why not an input on your mixer? Then use whatever control is convenient in your pile of outboard gear to kill the mic when running digital modes. Or pad the mic level back down & use K3 mic input. Another topic is why use the outboard gear at all? Gate & limiter aren't necessary with levels set correctly. K3 already has compressor & EQ. I can't deny the rack of gear with blinking lights looks very cool 73, Josh W6XU Sent from my Technophone PC105T > On May 9, 2014, at 4:40 PM, Slava Baytalskiy wrote: > > By "my audio stuff" i mean a mic. > I'm using a Shure SM58, into a mic preamp, into a > gate/compressor/limiter/de-esser into an EQ into a mixer into the K3's > line-in. > So line-in is taken.

Re: [Elecraft] Making a Signalink cable for the K3's 8-pinmicconnector
Hi Jim, Thanks for the detailed reply. I have never tried JT65 of any flavor so I have no basis for comparison and accept your conclusions. Since I'm more of a DXer than a contester, I don't often use N1MM or any of the other programs that support 2Tone. I use DXBase for general logging and AXETTY (an MMTTY variant) on RTTY. AXETTY, by Joe, WA6AXE, speaks to DXBase. I asked Joe whether he would port to 2Tone, but he's not interested. In my (very) limited use of N1MM on RTTY I have used multiple decode windows. It appears to me that 2Tone might be superior once it locks to the signal, but on quick exchanges that doesn't seem to happen. Maybe something I'm doing wrong. Nevertheless, not a big issue for my style of operating. Although licensed in 1958 I was never on RTTY until I got the K3 about 4 1/2 years ago. The passing of my wife three years ago took a big hunk out of that time. Even so, with very modest antennas I've now worked 210 countries on RTTY and it's become my favorite mode. Maybe I should give JT65 a try, except as a former "copy-by-ear" EMEer I think it's "cheating" on that mode :-) 73, Wes N7WS On 5/9/2014 2:00 PM, Jim Brown wrote: On 5/9/2014 1:26 PM, Wes (N7WS) wrote: Likewise, after your glowing recommendation of the US100, I bought one. Hi Wes, I did my testing with JT65HF on he HF bands, with the K3 output feeding both one Thinkpad internal sound card and the Tascam feeding a second Thinkpad. I did the same comparison between the Numark and internal, then between the Tascam and the Numark. My criteria was the number of good decodes for each 1 minute pass. The Tascam and Numark boxes consistently decoded twice as many signals per 1 minute pass. The internal sound card rarely decoded a signal weaker than an indicated -12, whereas the Tascam and Numark regularly decoded additional signals down to -20, with occasional -22 decodes. I attribute that to better performance near the bottom of the A/D. When comparing the two USB boxes to each other, roughly once in ten passes, one would decode a signal that the other would not, but neither was better than the other -- on one pass the Tascam would miss a station that the Numark copied, then 5-10 minutes later the Numark would miss a station that the Tascam copied. This was quite extensive -- in addition to watching the nigher bands, I even let them run overnight on 160, then compare decodes the next morning. I found performance "a bit better" with RTTY, but did no equivalent testing to substantiate that, because I found the JT65 results far more quantifiable and repeatable. So for RTTY contesting, the Tascam is on one rig feeding one laptop, and the Numark is on the other rig, feeding the other laptop. Now that we have 2Tone as an alternative to MMTTY, I've been running three decode windows per radio, and the most I can say to describe the result is that they are about equally good, but on almost every pass, one of the windows will copy something that one of both of the others missed, not no consistent advantage I've been able to discern to one over the other. The real advantage is that you have three looks at the same signal, so you tend to ask for far fewer repeats, AND I have changed to not repeating the exchange.

Re: [Elecraft] Making a Signalink cable for the K3's 8-pin micconnector
Normally, I defer to your expertise. However, my experience is that the SignaLink is no better or no worse than the built-in sound card in my Lenovo T400 laptop. Likewise, after your glowing recommendation of the US100, I bought one. I saw no difference with it either. It appears to me that the RTTY SNR is set at the K3 Line Out and a lower noise/higher dynamic range sound card is unnecessary. If I'm wrong (always a distinct possibility) I would like to know how. I "retired" the SignaLink mainly because I was out of USB ports on the laptop.

Re: [Elecraft] K2 Control Board Issue
Glenn, R7 has no association with the voltage display - it does however have a lot to do with the current display. The voltage detection is done by the voltage divider consisting of R9 and R10 on the control board. The voltage measured at the junction of R9 and R10 (or U3 pin 5) should be 20% of the 12 volt input (as measured at P7 pin 2). I would wager you have a bad solder connection at R10. Measure the resistance from U3 pin 5 to ground - it should read 196k. As for R7 reading zero ohms, I would suggest you look for a solder bridge. If you find none, then remove U6 and remeasure. Should the R7 resistance come up to normal, then U6 will have to be replaced - and be careful about taking proper anti-static measures. Is there any chance you are using an old VOM or VTVM to check resistances? If so, know that those can cause solid state devices to conduct and may even cause damage. Use a DMM - those do not use high voltages for resistance measurements. 73, Don W3FPR On 5/9/2014 1:14 PM, Glenn Haffly wrote: Doing something I should have not done , I managed to blow up Q11on the control board.

Re: [Elecraft] Automotive Radar Potential Interference
My teams and I have developed automotive radar for adaptive cruise control and collision avoidance for several decades. They generally operate at 76-77 GHz with only milliWatts of power and significant frequency modulation. The range is typically up to 150 M. Furthermore, with high gain antennas, the millimeter-wave beam is very directional and the power is readily absorbed in the environment. There should be no concern about interference with other users of this spectrum.

Re: [Elecraft] Making a Signalink cable for the K3's 8-pin mic connector
Slava, If you are using a microphone input for data modes, adjusting the mic gain input for the data mode interface will affect the mic gain with your microphone. You will probably find this annoying. The usual arrangement is to configure voice modes to use the front- or rear-panel microphone input, as appropriate for your microphone, with the mic gain level set properly for the mike, and then to configure Data modes to use Line In, with the Line In level set appropriately for data mode input. The Line In level and the microphone input level are independent, so adjusting the Line In level for data modes has no effect on microphone input levels, which is not the case if you use a microphone input for data modes. If you use a sound card for voice keying, you can use the same sound card for Data modes. You would configure MIC+LIN to be on for voice modes and off for Data modes. By controlling the microphone input level to the sound card when you use it as a voice keyer, you can set things up so the Line In level that works for data modes is also the correct setting for voice keying in voice modes. You don't need separate sound cards or interfaces for Data vs. voice modes. 73, Rich VE3KI W2RMS wrote: Hi Don, list!

If it's to/from an internal sound card, it's probably worth replacing with a decent USB audio interface. FWIW, the SignalLink box is highly overrated, thanks to advertising by those who sell it. And "help" info on the DX Engineering website to solve RFI issues strongly suggest that it has a Pin One Problem. There are several USB audio interfaces sold mostly to DJs and home studios that work very well for us. Several years ago, I bought and tested thoroughly two low cost units that work VERY well -- much better decoding of digital signals, especially weak ones. The simple Numark stereo interface costs about $35, the now discontinued Tascam US100 was $75, and was replaced by a US120 that costs more. They work equally well, and neither has a Pin One Problem. 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 arch...@mail-archive.com

Re: [Elecraft] KPA500 Aux Cable Pin 11 Problem with Preamp
I also had a problem with an external preamp for 6 meters. This one I powered from the station 13.8V power supply so it was always on. The problem came about when I changed bands to the internal 2M transverter and inadvertently activated the RX ANT. Instant relay buzz from inside the K3, I assume it originated from the KXV3A board. Removing power from the external preamp cured the buzz. A bit of a mystery in that the KXV3A has DC blocking caps on the IN and OUT connectors as does the ARR P50VDG preamp. As my activation of the RX ANT was inappropriate for 2M, I have not made an issue of the anomaly. I am still very curious as to how and what caused the relay buzz? Everything is the shack is single point grounded including the station power supply. 73s Jim, W4ATK On 5/9/2014 7:34 AM, Mike K2MK wrote: I had a problem that I remembered reading about on the reflector when I hooked up my new KPA500 to my K3 with PR6/10 preamp using the Elecraft Aux cable and the companion Y cable.

I think an alert should be added. 73, Mike K2MK -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA500-Aux-Cable-Pin-11-Problem-with-Preamp-tp7588821.html Sent from the Elecraft mailing list archive at Nabble.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
[Elecraft] 4 metre module (70 Mhz) module possible for the KX3
Hello Wayne, Thank you for the information on the 2 metre module for the KX3, I will be ordering one on Friday 16th. I would also be interested in a 4 Metre module as that band is getting very popular in region1. Just an idea Wayne, would it be possible to have it mounted in a seperate enclosure, so as to avoid opening up the KX3 to change bands. Just my thoughts and I realise it may not be possible for technical reasons. May I wish you and all at Elecraft a sucessful time at Dayton. 73, Barry G4DBS On 09/05/2014 02:17, elecraft-requ...@mailman.qth.net wrote: Message: 28 Date: Thu, 8 May 2014 17:57:11 -0700 From: Wayne Burdick To: Elecraft Reflector, "k...@yahoogroups.com" Subject: [Elecraft] 4-Meter (70 MHz) module possible for the KX3 Message-ID: Content-Type: text/plain; charset=us-ascii Hi all, We'll be taking orders for the KX3-2M module, at Dayton and via the web, starting next Friday, May 16th. (Please don't call Elecraft about this yet -- we won't be set up to take orders until then.) Meanwhile, we're thinking about doing a 4-meter version. 4 meters is not available in the U.S., yet, but it is available in many countries in ITU region 1 (Europe, Africa, Middle East, etc.). For details, see: http://en.wikipedia.org/wiki/4-meter_band. A KX3-4M would be identical to the 2-meter version, with about 3 watts output, a very low noise figure, and all-mode operation. It would use the same PCB, requiring only component changes. Unfortunately there isn't room for both 2- and 4-meters on one module. Any interest in a KX3-4M? 73, Wayne N6KR __ 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
[Elecraft] 4m for KX3
If I wanted both 2m & 4m modules - how easy to swap out to change bands ? I know you will be using the SMA socket - so will there be a connection on the board or will the antenna cable be hard wired on ? I don’t think the change would be needed on a regular basis - but it would be good to have 4m for field days and 4m contests. Of course the Elecraft option would be have 2 KX3’s - one for each band !

[Elecraft] KPA500 question
For those who might be interested, I do have a ICOM PW-1, a SS 160- 6m, 1KW+ output PA, for sale. It will operate similarly to the KPA500 and KAT500 combo, with automatic band changing and auto antenna tuning, with its own built in ATU. The unit can be located remotely and controlled by small desk mounted Control box. Also for those interested in getting prepared for 4M(70MHz), I have a PA that covers both 6M & 4M. It's a UK manufactured Discover PA. that uses a GS35B as the final. Also for sale is an AL 1500. Of course I would much prefer sales within reasonable driving range. Contact me off line if interested.
