[Elecraft] KX3 transverter mode
A friend stopped by to show me his KX3 - happened to be during CQWWCW, so I could put the receiver to real world tests easily, even though all I have for an HF antenna is a random wire. It took me only a few minutes to remark- this is a K3 in a small box, not a cute toy. Feels and behaves like a K3. Smooth. Clean. But what do you expect? Its an Elecraft. We stuck some paddles into it and worked (40M), with some effort, a very sharp op in Madeira. 6 watts to a random wire from Ca. The VE6 was one call. While looking the radio over, I tried to figure out a way to bring out the exciter power level - I have a 28 MHz IF on my Xband radio, and the KX3 would fit on the TWT mounting plate eliminate a bunch of wiring, etc. So the question is: Is there a practical way to get 0 dBm class power levels out of the transmit section? Separately from the receiver connections- my transverter has separate RX and TX lines. I REALLY don't want to have to use a 30 dB power pad and yet another relay to split RX and TX I note that there is a 2M built in transverter coming - same question here, many other microwave ops have 2 meter IFs in their radio, and could use IF levels out of the transmitter It also occurs to me that a KX0 - or even a full KX3 - might be an excellent remote head for single VFO operation of a remote K3, instead of a K0 Robin WA6CDR __ 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 VLF transverter?
I am working up a design for a 470-480 KHz transverter to have a 25w output. One version would use the K3 in TEST mode on 10.470-10.480 being mixed with a high stability 10-MHz OCXO. But also looking at a version that would use 3.570-3.580 mixing with a 3.1 MHz xtal osc. for the usual ham radio that will not transmit outside of a ham band. A built-in 20 dB 50w attenuator would lower HF transmitter levels. This would lower 25w to .25w and an adjustable 0-20 dB attenuator would lower the level for correct input to the mixer. A low-level sma connector would permit driving the adjustable atten directly with up to 100mw. I already have a prototype mixer-buffer that outputs 10mw for transmit-only. I chose 25w as antennas at 500-KHz exhibit very low efficiency (my 43x122 foot inverted-L radiates 4.15w ERP with 100w output from my 500-KHz transmitter). A 25w output would result in about 1w ERP which is the highest permitted level expected for the new ham band. I still have to chose a good preamp design and final amp design. I will use pin-diode switching. At this point its only on-paper idea, but I hope to be early in the market when the band is finally offered for ham use.

Re: [Elecraft] [K3] Band data problem
A follow up to the K-Line and RCS12 integration. The problem was that the RCS12 was excessively loading the band data lines. The fix was additional drive on the pullups on those lines inside the K3. I used 820 ohms in parallel with each of the internal 2.2K pullups and all is now working well. Details: The RCS12 band inputs drive a 2N3904 common emitter buffer using a 1K base drive resistor. This puts one Vbe drop plus 1K directly on the K3 Band Data lines. These lines have a 2.2K pullup and a series 220 protection resistor for a total of 2.4K to +5v. A quick bit of math shows that when this is loaded with the RCS12 the resultant voltage on the band data lines falls below 2V. Although the RCS12 is happy, anything else expecting to read the band data lines will show zeros. The KPA500 will show 5.3Mhz (60m) indication as a result. Paralleling the 2.2K resistors with 820ohms brings the combination to 600ohms which in series with the 220ohms results in 820ohms to +5V which when driving the RCS12 inputs yields 3V remaining on the band data lines. This provides a sufficient level for a 1 with reasonable noise margin.

Re: [Elecraft] K3 rig control/CW serial interface
I use serial cable only as well using RTS DTR for keying from N1mm and logger 32. originally I had some issues with some messed up keying using the USB- serial adapter. I discovered that the Mother board did have RS232 it just wasn't on the back of the computer. I just needed an adapter cable that had DB9 at one end and a molex connecter that attache to Motherboard. this solved the issue I am guessing it was some latencies in the USB adapter. Talking to the guy at the computer store he told me that most new motherboards still have a serial bus but rather than a DB9 port on the back just have 9 pin connectors on the board so you need the extra cable. it just fits into one of the unused expansion slot openings and has a ribbon cable from the DB9 that goes to the connector on the MoBo. works fine for meI don't run it more than 30WPM but that's just because faster is way beyond my own abilities.

Re: [Elecraft] [K3] Band data problem
Hi Joe There's certainly more than one way to deal with this. External buffer chips are an inexpensive solution. I didn't want yet another piece of clutter in my already box and cable littered shack so I chose to mod the K3. The K3 driver chips are not an issue at all. Any additional external pullup would add to their load but would also provide the desired additional pullup drive and make it possible to increase the value from 820ohms to perhaps 1K. The KAT500/KPA500 add a fraction of a milliamp in total so they are not an issue. They are the only devices other than the RCS12 on the band outputs in my case. The only other consideration is that the increased internal pullup drive (lowered resistance) puts more load on the 5v regulator sourcing current to those pullups. Again not an issue. 73 jim ab3cv On Sun, Dec 2, 2012 at 9:41 AM, Joe Subich, W4TV li...@subich.com wrote: I would be careful when decreasing the value of the pull-up resistors in the K3.

Re: [Elecraft] [K3] Band data problem

[Elecraft] KPA500 # 1170 up and running!
All: KPA500 #1170 was born this morning at 11:30am, It is powered up and alive! Fun build. I am continually amazed at the precision with which the metal panels fit in Elecraft kits. After building my K3 and P3 and rebuilding my K1, the accuracy of panel fit continues to impress. I dont know who invented the 2D connectors, but they sure know how to measure and drill accurate holes! The amp goes together quickly and easily. Big pains are the transformer and the installation of the heat spreader. Instead of screws, why not bolts? Felt queazy bending the IC's leads down far enough to get at the screws on the mounts, then bending them BACK upright! Small hex head bolts would have been better for this (and safer). The Safety Interlock switch should mount higher on the side panel and actuate from the top cover instead of with the funky and clunky actuator made from a standoff and a screw. Why all the needless complexity? Worst thing, though, is the whiff of Chineseium vapors you get when you open the box with the toroidial transformer and rubber pads. Smells just like a Harbor Freight Tools store! Seems to be airing out after installation, however. But all in all, a fun morning, concentrating on assembly and not worrying about all the rest of the stuff that will hit my desk tomorrow morning. Now on to the interfacing of the KPA500 into my station, replacing my existing ALS600. But the oldest kid came over to visit for lunch, so that will have to wait until tonight! -lu-W4LT- K3-P3-KRX3-K1-KPA500 __ 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] Band data problem
I would suggest if modification to the RCS-12 is in order, the 2N3904s be changed out for switching FETs such as the 2N7000. The change Jim made will result in only 8 ma of drain current for the drivers in their off state. I believe the band data drivers in the K3 are similar to the KEYOUT-LP driver which is rated to sink up to 10 ma. according to the K3 ACC connector information. 73, Don W3FPR On 12/2/2012 12:24 PM, Joe Subich, W4TV wrote: I didn't want yet another piece of clutter in my already box and cable littered shack so I chose to mod the K3.

Re: [Elecraft] Keying the K3 for RTTY
Bill, If by keyer you mean paddle, then FSK-D data mode should work. AFSK will also decode, but not encode. if you mean a keyer and not paddles, then it won't work. The K3 must encode from the paddles, not from an external keyer, to send PSK or RTTY using the built-in encoder. 73, Lyle KK7P I wanted to amke a few RTTY contacts in the recent contest.

I'm not holding my breath for a call from Mr. Yaesu-san if my FT-847 quits. :-) 73, Fred K6DGW - Northern California Contest Club - CU in the 2013 Cal QSO Party 5-6 Oct 2013 - www.cqp.org On 12/2/2012 11:48 AM, iain macdonnell - N6ML wrote: So I was happily running (100w) in the 10m RTTY contest, when suddenly my stream of callers ground to a halt. I looked at the meter, and saw that I wasn't making any (significant) power any more (~1w). The K3 is reporting high SWR, but an external meter is not. All other bands are transmitting fine (incl. 6m). The antenna is OK (hears well, and another transmitter sees normal SWR on it). What would cause high SWR / no power out on 10m only? __ 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 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] KX3 Tuning noise
Rick, with PREAMP off and AGC-Fast the noise is measured as follows (peak values), depending on band (quiet ) and antenna: on 10m, on a vertical: 1.1 dbV, on the beam: 1.8 dbV on 12m, on a vertical: 3 dbV, on the beam: 2 dbV on 12m, on a vertical: 2 dbV, on the beam: 1 dbV To get an idea how these values are related to S-points: S1 indicator on: ~3dbV S2 indicator on: ~6.5 dbV Which means if signals are well over S1 you won't hear the noise. However, the KX3 can well receive signals on the edge, and then it becomes distracting. 73 Gernot DF5RF Am 02.12.2012 18:04, schrieb Rick Tavan N6XI: What does it measure with an antenna connected? I can barely hear it on 10M when the band is dead. If there are signals, it's inaudible. /Rick On Sat, Dec 1, 2012 at 8:44 AM, g...@gmx.net mailto:g...@gmx.net wrote: I measured the noise on 10mtrs using the built-in audio dbV feature - it says 11 dbV above noise (no antenna connected).

[Elecraft] KX1 KXPD1 tips?
I'd appreciate any tips on how to get my KX1/KXPD1 to behave better. In the past, I've found the keying errors to be controllable by limiting my speed to 22wpm. But today, I used the KX1/KXPD1 on a cold and damp mountain summit (SOTA W2/GC-104) and I found it almost impossible to send code without the rig inserting extra cw elements. I decreased speed to 18wpm, but it still was VERY problematic. Appreciate any advice on making the KXPD1 more reliable. 73, Barry N1EU -- View this message in context: http://elecraft.365791.n2.nabble.com/KX1-KXPD1-tips-tp7566586.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
[Elecraft] Thank You Elecraft Employees
I would like to share my thanks and appreciation to Elecraft employees for their excellent products and support. I am a relatively new K3 and KPA500 kit owner. I was happy with my purchase during assembly, and have been happy ever since. I have a KAT500 kit on order now too. I shared my equipment with some volunteer radio operator friends during Field Day and SKYWARN Recognition Day this year, at the Fort Worth National Weather Service forecast office. I do not believe any of them had operated Elecraft radios before. They had experience with various other makes and some high-end models. All who had a chance to operate my equipment were impressed. Everything functioned flawlessly. Although I have not worked directly in manufacturing for many years, I started my career at a major commercial 2-way radio manufacturer 36 years ago, introducing, manufacturing and testing radio products. I may have some small idea of the effort it takes to design and manufacture a quality radio product, and exceed customer expectations. You have done so for me. Thank you, and be proud of all that you have accomplished together! I hope you continue to be successful for many, many years to come. -- Sincerely, David McAnally WD5M Have a Merry Christmas and Happy New Year __ 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 SDR-IQ from re-space
Howdy K3' people: I did some more research on my goals of using my new K3, Sub-RX with matching 8-pole, for low-low bands. If anyone uses the actual SDR-IQ with a K3, I would like some guidance. And I' would like to ask is it possible to listen/hear a particular point on the displayed segment when used in conjunction with the K3? On-List or direct email, either way, I'd like to get one this week, so answers would really help out. :-B -- 73 KD7YZ Bob __ 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 SDR-IQ from re-space
Bob, What are your specific questions? I have the K3 with SDR-IQ here. I've used it both with the IF connection (as a panadapter) and with an RF connection (RX Out/RX In and a splitter) for CW Skimmer. It was in use for about a year but is off-line at the present - I'm not completely sure the receiver hasn't been damaged and don't have the time to trouble shoot it right now (either RX problem or computer issue). 73, ...
