Re: [Elecraft] KE7X KX3 Book and Configuring: KX3, K3, KPA500, and KAT500
Jack, Thanks for the detailed explanation. So, if the K3 pulls the keyline to ground and the STBY/OPER switch is inoperative as a result, then why would power cycle on KPA500 change things. I mean, I assume that the keyline is still pulled to ground by the K3. But, I admit that I am not an electronics guy as you others so I do not fully understand all of the stuff that goes on in these things. 73, phil, K7PEH On Apr 22, 2014, at 10:18 PM, Jack Brindle wrote: > There appears to be some misconceptions in this discussion.

Re: [Elecraft] KE7X KX3 Book and Configuring: KX3, K3, KPA500, and KAT500
There appears to be some misconceptions in this discussion. First, the information flow from the K3 to the KPA only occurs on the band lines and the key line. Auxbus communications is one-way, from the KPA to the K3. The KPA does not listen on the Auxbus. There is also something else going on that is in play here. When the K3 is powered off, the pull-ups on the band lines (and the key line, I believe) continue to work. They continue to pull the lines to Vcc. But with the K3 off, Vcc is now 0 volts. This means that a short time after the K3 powers off the KPA will see all zeros on the band lines, and will switch to 60 meters. After this, RF coming into the KPA will cause it to switch to the appropriate band, and all band switching will occur with incoming RF as long as the band lines do not change. Of course, there is one other signal in play here. The Key line is important since it causes the KPA to switch into transmit. We have seen the K3 pull the Key line to ground at times, which just may be what you are seeing. If the KEY line is active, the KPA will not switch from STBY to OPER. For this to happen the KEY line must be high. The best way to connect two transceivers to the KPA is to use a physical switch to select the transceiver. A five-pole two position switch will do for the band and key lines, plus a coax switch of the RF. In short, you may get things to work with the description from Fred’s book. But if the key line becomes driven low by the “off” transceiver for any reason, you can expect weird things to happen.

Re: [Elecraft] KX3 and FLDIGI
Consider disconnecting the RS-232 connection and leaving the audio connection. Then use VOX to key the transmitter.

Adrien,
I am confused by your statement that you see "AUDIO A" on the LCD.
There is no "AUDIO A" mode and no characters on the LCD indicate that
information. Yes, there is a "DATA A" Data sub-mode that should be selected
for soundcard data modes (except for RTTY where "AFSK A" provides added
advantages for RTTY).
For most soundcard data modes, you would want to use DATA A submode in USB.
RTTY normally uses LSB, but RTTY is best used in AFSK A data sub-mode.
Your data mode software application and the KX3 default settings may be
"fighting each other".

[Elecraft] KX3 and WSPR
I just downloaded and installed WSPR and WSJT-X to run on my KX3. Both work fine except that CAT control fails with WSPR. Both programs TX and RX just fine using VOX for PTT. No change in the hardware setup -- I quit WSJT-X and started WSPR. Tried it several times. Both programs also work fine on my K3. The only difference in the setup is that I'm using a real serial port to talk to the K3, and an Elecraft-supplied KX3 to USB cable to talk to the KX3. Any ideas? 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] KX3 - RMS Express USB Data Mode
Keith, DATA A mode is exactly like SSB except that it automatically turns off compression and the TX EQ. So I would suspect that your problems have more to do with your software application and the commands it sends to the K3 than anything else. If your application is switching the KX3 to SSB mode rather than staying in DATA A submode, the compression and TX EQ settings you have for SSB would distort the data mode signal. Some software applications (older Ham Radio Deluxe and others) will switch the K3 and KX3 out of Data mode and into SSB mode. I don't know what Winmor and Pactor 3 will do. The solution that I have used is to not let the software change modes - in other words, do not click on spots or the data mode frequencies in the software, but look at the frequency and use the K3/KX3 VFO to move to those frequencies. BTW, if you are using the microphone input from your interface, mic bias should be set to OFF. If there are transformers in your interface box, the addition of mic bias can cause current to flow through those transformers and create distortion to the data stream. If you want to leave Mic Bias turned on, add a series capacitor (1 uF to 2.2 uF) in series with the AF line to eliminate the DC current through the transformer. 73, Don W3FPR On 4/22/2014 8:08 PM, Keith D Jones wrote: I got my KX3 and KPA100 this past February and have a lot of fun so far with it.

Re: [Elecraft] KX3 - RMS Express USB Data Mode
Hi Keith, I recently noticed something odd with my KX3. I thought that the RX EQ feature was inhibited in DATA-A mode, but it seems that it cannot be adjusted but is still applied. If I set the RX EQ in USB mode, I can still see the adjusted response in DATA-A mode, but I cannot adjust it in that mode. Perhaps this could be related to your issue, Keith? Is this normal? Also, it seems that in DATA-A mode, the audio drops off at about 400Hz (with the PBT with of 4kHz centred on 1.5kHz), whereas in SSB mode, it looks more like 200Hz. I wonder why this is? I would prefer more bottom end in DATA-A mode, I think.

[Elecraft] KX3 - RMS Express USB Data Mode
I got my KX3 and KPA100 this past February and have a lot of fun so far with it. I've been pretty frustrated the past few days trying to get satisfactory RMS Express performance using both Pactor 3 and Winmor. I built a cable for my Navigator and quickly had it working with the KX3 choosing the USB Data mode in the Radio Setup (K3 radio choice). I quickly made a connection and sent a small message. The past few days I have been trying to get my SCS PTCIIex Pactor 3 modem hooked up. I built a cable and rebuilt it 2 more times! The problem that I kept getting was a connection and either very slow and error (ARQ Repeat in RMSE and error light on TNC) or a disconnect after unsuccessful handshaking. Since I could connect I thought that maybe there was a problem with the cable. I checked with Elecraft and they felt good about my settings, Mic Bias On, Mic Gain 12 (4 solid 5th ALC bar flickering). I used the USB Data selection in RMS Express and that set the radio to DATA A. FL2 would show (I have the roofing filters). The poor performance continued, then by error I found that I had hit the mode button and gone to USB not DATA A - it worked great! Later changed back to DATA A and it was slow, hit Mode and it sped right up and the error conditions largely eliminated. Transferred a 31K file in 3-4 minutes. Back to a try with Winmor and the Navigator. With DATA A mode I gave up on the 31K file after 17 minutes. Trying in regular USB it took 6.6 minutes - about twice P3, more or less what I would expect. So I am totally confused about DATA A mode - using both sound card (Winmor) and TNC. I haven't had the opportunity to play with other digital modes as yet, but wonder whether the DATA A mode is advisable. Am I missing something?

Re: [Elecraft] KE7X KX3 Book and Configuring: KX3, K3, KPA500, and KAT500
Don, OK, I may be expecting too much. Actually, I am not sure if I was expecting as much as I was a little bit surprised by the behavior. I didn't think that the KPA500 and KX3 communicated with each other other than RF and Key line but maybe that was enough of a difference from the K3. The K3 of course in my case has the AUX cable connections with the KPA500 and KAT500. It is not a big deal as long as this is the way it is expected to work. I was not sure if I had done something wrong or not. But, just picked up W1AW/5 MS QRP power with the KX3. Actually, it was about 6 watts. 73, phil, K7PEH On Apr 22, 2014, at 4:57 PM, Don Wilhelm wrote: > Phil, > > I think you may be expecting too much. > Consider a parallel - a computer communicating with a printer.

Re: [Elecraft] KE7X KX3 Book and Configuring: KX3, K3, KPA500, and KAT500
I remember a while back I was asking the same question about using my K2 and KX3 with my KPA500/KAT500 combo, and Eric responded that the KPAK3AUX Optional KPA500 to K3 AUX Cable Set cable should be left disconnected when using another rig besides the K3. I was debating on using a DB-15 data switch so I wouldn't have to keep plugging/unplugging the cable. Mike AC6JA In a message dated 4/22/2014 4:44:58 P.M.

Re: [Elecraft] KE7X KX3 Book and Configuring: KX3, K3, KPA500, and KAT500
Phil, I think you may be expecting too much. Consider a parallel - a computer communicating with a printer. If you suddenly switch the printer cable to another computer, would you expect the printer to continue printing without any intervention? The "printer" in this comparison is the KPA500 and the two "computers" are the K3 and the KX3. It is not unreasonable IMHO to expect that a reset of the KPA500 would be required. If the KPA500 were simply an amplifier with no communications capability with the driving transceiver, switching from one source of RF input to another should proceed without regard to whatever is the driving device, but your KPA500 is more than "just an amplifier" because it can communicate with the K3 or KX3 driving transceiver. Expecting the KPA500 to switch data streams from two different transceivers with no intervening reset is not realistic. 73, Don W3FPR On 4/22/2014 7:41 PM, Phil Hystad wrote: So, is this normal behavior?

[Elecraft] KX3 and KXPA100 in high duty cycle use
Hi to the group I was in the W1AW/0 event from North Dakota and the NDQP event for about 12 operating hours over the last 4 days. My modes were RTTY at 80 watts and PSK31 at 30 watts. I quickly learned when I was getting ready that these modes caused the equipment to heat up too much. I found two 4 inch 12 volt muffin fans in my junk box and wired them in series to slow them down. One was placed to blow on the KX3 and the other on the KXPA100. The contest style operation stayed cool and I might have been able to do it without the fans if I had been careful. Several stations wanted to rag chew and one contact went on for over an hour. The OSC* peaked out at 42C and the PAI peaked out at at about 40C under these extreme conditions. Every other rig I ever used had a fan to operate under these conditions so I think it is reasonable the KX3 and KXPA100 need the fan too. I felt the KX3 and KXPA100 were rugged and reliable under these extreme conditions. Other people were concerned about the oper ation under these conditions earlier on this Elecraft reflector so I am sharing my observations. I worked 170 stations as W1AW/0 and 27 as W0CZ in the NDQP. I hope this information helps someone else get on PSK31 or RTTY.

Re: [Elecraft] KE7X KX3 Book and Configuring: KX3, K3, KPA500, and KAT500
Phil, Let me get this straight - the KPA500 is communicating with the K3, then you switch to the KX3 and the KPA500 does not talk with the KX3. If that is what is happening, I would expect that to be the case. The communications with the K3 is not synchronized with the attempted communications with the KX3, so a reset (power cycle) of the KPA500 may be required. 73, Don W3FPR On 4/22/2014 7:02 PM, Phil Hystad wrote: Some follow-up questions: OK, I have the KX3 and K3 configured with the KPA500 and KAT500.

Re: [Elecraft] KE7X KX3 Book and Configuring: KX3, K3, KPA500, and KAT500
Some follow-up questions: OK, I have the KX3 and K3 configured with the KPA500 and KAT500. Everything seems to work with one little exception. The exception: --- initial conditions, K3 is on and switched to use the KPA500 and KAT500. KX3 is off. --- using K3 and so on works fine with amp on or with amp in standby. --- I turn off K3.

I always have to cycle the power from the front panel on/off switch. What have I done or am I doing wrong? Note: all functionality works fine with this one exception. With the current power settings from the KX3 I am getting about 135 watts output from the KPA500 into my hex beam and also my 80-meter dipole. SWR is about 1:1 TUNED via the KAT500 on dipole and I usually operate the hex beam in bypass and this has a 1.2:1 SWR or there abouts. 73, phil, K7PEH On Apr 22, 2014, at 2:05 PM, Phil Hystad wrote: > Don, > > Thanks.

Re: [Elecraft] KE7X KX3 Book and Configuring: KX3, K3, KPA500, and KAT500
Don, Thanks. Clears everything up. I did find the key line interrupter. I had it in my Elecraft parts bin not knowing what to do with it when I got it.

Re: [Elecraft] KE7X KX3 Book and Configuring: KX3, K3, KPA500, and KAT500
Phil, You need to put the Keyline Interrupter on the K3 ACC connector, then use the RCA cable from the K3 KEYOUT jack to the KPA500. If you ordered the KPAK3AUX cable set, you have (or had) the Key Line Interrupter. See http://www.elecraft.com/manual/KPAK3AUX%20Cable%20Set%20Instructions.pdf. The KX3 must use the KeyIn of the KPA500, so the K3 must also use that same keying scheme - the KPA500 has a conflict if both the KeyOut-LP line in the ACC cable is connected at the same time as the RCA Keying cable from the K3, and that is where the Keying Interrupter comes in. 73, Don W3FPR On 4/22/2014 4:15 PM, Phil Hystad wrote: Fred or others...

Re: [Elecraft] Text Decode Issues (Cured?)
I"ve been really buring the midnight oil on this for the last couple of days and the more I fiddle with things, the closer I get (2 steps forward, three steps back, but still making progress). Now I don't know as any of these things have really made any difference, but I am making some kind of headway so I'll pass on what I'm finding; I noticed that the Key (factory Elecraft Key), was sending spurious tones. Sending a "Dit" would sometimes result in a "Dit-Dah". Upon further investigation, I found that the circuit board was actually moving slightly. The three hold down bolts appeared to be tight, but I tend to keep my key setup with very little movement, so I increased the distance, reset the board and tightened down the bolts (firm not killed, no need to crack the PCB). This seemed to cure the spurious tones, but I was still having problems with the "I - P" Combination (showing as "E - G"). On a guess, I went into delay and changed it from .23 to 0.000 with no change. Then I changed it to .5 and suddenly the "I-P / E-G" problem went away. Now this makes no sense to me as I don't believe that the delay would have anything to do with this problem, but then again, I'm not completely savvy with all the functions on this radio. I changed things back to .23 and the problem came back. Up to .5 and the problem goes away. So if anyone can explain that to me, I'd be smarter than I am now, but for now, I'm pretty happy that my sending is showing up properly. I'm posting this not as a 'cure', but simply to document what I have done that is so far, working for me. I have changed nothing else in terms of the setup so I think I'm on the right track. 73 -- View this message in context: http://elecraft.365791.n2.nabble.com/Text-Decode-Issues-tp7587553p7587669.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

Re: [Elecraft] K3 intermittent receive issue
"Any or all of the above" - several people have suggested good ideas. The strongest possibilities are a loose TMP connector or a multi-way connector that needs re-seating. Since the faulty connection is "right on the edge" between working and not working, even a very gentle tug on a TMP connector or a gentle jiggle of a board should reveal the problem. The best tool that I have found for inserting, checking and removing the TMP connectors is a pair of artery forceps. The finger loops and the click lock give far better control than long-nosed pliers (smart people, those surgeons!). Forceps are available in several different sizes and shapes, and probably the best choice for working inside the K3 is the straight 6-7in pattern. They are cheap and easy to find on eBay, and well worth trying. Since Chris is in the UK, a good alternative to Deoxit for treatment of connector pins is Contralube 770 which is available from Maplin. Regarding the rear-panel SO239, I was the person who suggested making a direct ground return between the connector flange and the KANT3 or KAT3 board. OK, so "it works already" and "7999 other K3s can't be wrong"... but it still isn't good practice to make a single-wire link to the center pin while leaving the equal and opposite return current to find its own way back to the board through a single-point connection between the rear panel followed by a long, thin support pillar. The new connection is made by attaching a solder tag under the 4-40 screw (as seen in the Assembly Manual, Figure 29) and another tag to the nearest point on the flange of the SO239. No wire is needed; the two tags are simply bent until they overlap, and then soldered to make a shortest possible return connection. Ohm's law dictates that this will now be the preferred return path, so the poorer path through the metalwork is the one that becomes redundant. 73 from Ian GM3SEK >-Original Message- >From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of >Jim LeFevre >Sent: 21 April 2014 21:03 >To: elecraft@mailman.qth.net >Subject: Re: [Elecraft] K3 intermittent receive issue > >I recently corrected a similar problem on the K3 I put together.
