[Elecraft] Elecraft CW Net Announcement
Good Evening, The weather has been cool this week but I have seen a few minutes of sun. More flowers are blooming and I think most of the frost danger has passed. Logging season is in full swing. After a full month of gravel trucks driving by starting before dawn I saw my first truck load of trees bound for St. Helens. Each of the gravel trucks has a trailer behind it so my road is getting flattened by the sheer weight of each load. Propagation has been decent each morning on twenty meters with just a little noise and some QSB. It is good to be able to hear all of a contact with strong signals. Only last year it was hard to do so. I read yesterday in Sky & Telescope that the peak of this solar cycle is due in 2013. They also mentioned it will be one of the weaker cycles recorded. Oh well, I'll have to wait until the next one I guess :) I do remember the 1958-59 period when I started listening to shortwave. It was fun. IGY was only a year in the past so there was a lot of attention being paid to the newly found Van Allen belts and the satellites going into orbit. Echo 1 and 2 were fun to watch from the backyard. It is hard to imagine it has been 50 years since Alan Shepard took that first sub-orbital flight. It is also hard to imagine how very little progress we have made in space since 1969. If anyone is interested in acting as a relay station on either net please email me. I will turn the net over to you for a few minutes so you can call areas in my skip zone. It sure would prove helpful to those I cannot reach directly. Please join us tomorrow afternoon and evening. 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP help) Sunday 2200z (Sunday 3 PM PDT) 14050 kHz Monday z (Sunday 5 PM PDT) 7045 kHz Stay well, Kevin.

Re: [Elecraft] K3 + fldigi problem...
I suspect you are generating PTT via radio commands with FLDIGI but DigiPan does not support radio commands. With PTT from SignaLink (the built in "VOX") and FLDIGI you can generate a "RACE" condition. Either disable the "command PTT" in FLDIGI or disable the "VOX" PTT in Signalink and you will probably eliminate the problem. In some cases it appears that the transceiver CPU sees the "PTT OFF" command via serial control but says "I still see a hardware PTT so I will keep transmitting" but the controller is busy when the hardware PTT drops and the hardware PTT change gets "missed." I believe (but have not been able to create the necessary timing) that the "hang" occurs when the hardware PTT drops less than 10 msec after the "PTT OFF" command. 73, ...

[Elecraft] K3 + fldigi problem...
Does anyone recognize the cause of the following problem? 1. First, the details of hardware/software: (a) WIN 7 (32 bit) Dell XPS, on-board sound and also Infrasonic Quartet PCI card. Both sound cards are never active at the same time (e.g. the on-board sound is shut off in the BIOS when the Infrasonic card is being used.) (b) SignaLink USB (c) K3/100 & P3 (d) FLDIGI 3.21.9 7/or DigiPan. FLDIGI is run using RigCat and the K3.xml file. The SignaLink can be run off either sound source. The problem is the same with either. BPSK31 (e.g.) can be run off either FLDIGI or DigiPan. The problem only occurs with FLDIGI, not with DigiPan. 2. The problem: (a) Transmission initiates correctly with both FLDIGI and DigiPan. (b) When transmission is terminated with FLDIGI, the K3 is left in "TX" mode -- that is, the red LED under the Power switch remains on, although the SignaLink powers down properly and the PSK idle carrier is no longer transmitted. (c) Pushing any front panel button on the K3 changes it over to RX mode. (d) When transmission is terminated with DigiPan, the K3 changes over to RX mode properly. (e) In either case, during transmit, things are working OK -- one can proceed with a QSO.

[Elecraft] [K3] Programming - "ER" commands?
Can anyone give the syntax of the K3's "ER" commands? For instance, "ER0E804032;" apparently reads k3 memory location 10, but at first glance I don't understand the format of the command or its response. The ER commands seem to be a much better way of interacting with the K3 for certain things than those published in the Programmer's Manual. Thanks!

Ed, I had the same question, so I asked Elecraft. You've got the right part. Here's my email to them: "...RF E690007, a 33 uH selenoidal inductor. The color code should be orange-orange-black, but it looks like brown-brown-black to me. "brown" and "orange" are pretty close together, so I assume it's just the part maker's idea of what orange should look like. However, I thought I'd check with ya'll to make sure it's alright.

Re: [Elecraft] K2 KPA100 transmit test: fail
I've heard many extremely powerful signals reduce the audio output from even the best receivers in commercial communications facilities. It's a very common phenomenon. Glad all is okay Brian.

[Elecraft] K2 Inductor identification question
All I have identified all the inductors from the parts list with the exception of 2. The first is what I believe to be L5. L5, I think, is a green bodied inductor that looks like brown brown black. So I'm wondering if the brown is actually orange due to the printing on a green back ground. The second one is RFC15 which is a sub miniature solenoidal, what I have looks to be green brown green. So I'm not sure what to do until I have confirmation that what I have will work. 73s, Ed KE7HGA -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-Inductor-identification-question-tp6340883p6340883.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

Re: [Elecraft] K2 KPA100 transmit test: fail
What is most likely to have fooled you is that if you are transmitting into a dummy load, then what you are hearing in an antenna-less nearby second receiver is miscellaneous leakage from the K2 case. This could easily change when the termination of the low power stage changes its termination from the dummy load to the input of the 100 watt stage. Glad the direct measurement is FB. Enjoy. 73, Guy.

Re: [Elecraft] K2 KPA100 transmit test: fail
Hi all, Here's the results of my power measurements: Requested/Measured Power 5 W --> 5.81 W 10 W --> 11.06 W 11 W --> 11.93 W 20 W --> 18.22 W 30 W --> 30.25 W Looks pretty good to me. The take away lesson is not to rely on a separate receiver to judge signal strength. It's still a mystery to me why there is such a drop off in heard signal strength going from 10 to 11 W, but the wattmeter doesn't lie. Thanks to all that helped out and putting my mind at ease!

Re: [Elecraft] K2 KPA100 transmit test: fail
There's a new revision of the DL1 manual (Rev C) that should appear on the Elecraft web site soon. It has this new formula: P(watts) = (V + 0.25)2 /25 where V= volts and 0.25 is the RF voltage drop across the diode. Ron AC7AC -Original Message- Hi all, Thanks for the tips. I might have taken the instructions too literally and not taken into account the receiver attenuating the signal. However, I did confirm that AGC is turned off on the receiving radio, so that can be ruled out. What is hard for me to understand is that the signal is load and clear at 10 Watts, but drops off significantly at 11 Watts when the high power relay kicks in. In my mind, there shouldn't be that much of a difference from 10 to 11 watts, one way or the other, to kick in any attenuating circuits or AGC. Measuring the actual power will be my next step: I'm relying on using a DL1 and taking the voltage measurements and converting it into power. Now this has me worried that I'm using the wrong formula since I've seen at least two floating around on the reflector. Here's what I'm using: Power (Watts) = (2x((DC Volts + 0.15)^2))/50 Or: add 0.15 to the measured voltage, squaring the sum, multiplying the result by 2, and then dividing the final product by 50 Can you all verify that this is the correct Power formula for the DL1? I'm using the DL1 up until about 25 watts, then I'm switching over to a 100 Watt dummy load. 73 N5BCN - Brian __ 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 S meter vs P3 S scale
Alan, Thank you for this, I have been wondering whether my P3 required calibration. I am not sure if this is mentioned in the manual but if not it should be. The P3 is a new product and some of us are still learning. The forum once again proves valuable. 73 Doug EI2CN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Alan Bloom Sent: 06 May 2011 23:00 To: Jim Miller KG0KP Cc: Elecraft Reflector Subject: Re: [Elecraft] K3 S meter vs P3 S scale The reason the P3 reads lower than the K3 on noise or SSB signals is that each display point on the P3 screen covers only a small bandwidth. As explained in the manual, each display point is about 1/450 of the span. For example, if the span is 45 kHz, then each display point only covers about 100 Hz. You'd see the same effect on the K3 if you narrowed the bandwidth from 2700 Hz to 100 Hz. The S meter would read 10 * log (2700/100) = 14 dB (2-3 S units) lower.

Re: [Elecraft] K3 and HRD turning AGC off
It happens exactly the same to me, totally unpredictable and not relevant to a sequence of cat command I may send via HRD ! It's really funny and frustrating :-( I'm using HRD into a virtualized XP Pro machine at a Mac Mini , using a 232-Usb adapter. In the past I had similar strange behaviour using HRD 4 under XP Pro virtualized at an Opensuse pc and the rig was 756 Pro III. In that case suddenly and without any reason the AF gain went to the maximun (my wife enjoyed it so much).

Re: [Elecraft] K3 and HRD turning AGC off
Absolutely. I had this problem as well with HRD. I was never able to resolve the issue. Since moving away from HRD to al Mac based software I have not seen the problem again. I, for one, do not think it is an elecraft problem either, although it is hard to imagine why HRD would do this when returning from SSB(Voice and Data) transmit (this is when I observed the problem). The consensus of support was it was RF in the shack. But, if that is the case, why just AGC?? A frustrating problem to say the least. 73s Jim, W4ATK > > > On 5/7/2011 10:14 AM, Stephen Prior wrote: >> I have (and I think I reported some time ago) been experiencing occasional >> AGC misbehaviour where the AGC would suddenly turn off.

Re: [Elecraft] K2 KPA100 transmit test: fail
As a receiver gets heavily overloaded it's not uncommon for the audio output to drop as amplifier stages are driven so hard they become attenuators. As others suggested, the *only* way to confirm is with a wattmeter. 1) What does the wattmeter built into the K3 say? 2) Did your K3 pass the TX Gain procedure without errors?

[Elecraft] K3 and HRD turning AGC off
I have (and I think I reported some time ago) been experiencing occasional AGC misbehaviour where the AGC would suddenly turn off. Insofar as I can remember this has only happened on ssb and up until now I had formed the impression that I may have rf getting in somewhere as it only seemed to be apparent after going back to receive. However, three times today the AGC has without warning turned off, and not whilst transmitting. (I have been more active than normal, exercising my GR call!). On one occasion I was listening on 15m usb and as I was looking at the display I saw the 's' disappear it was probably coincidence that a station had just started to call on the frequency, but maybe not. This time I have been outside cutting grass and returned to find the AGC had turned itself off again. I am running Ham Radio Deluxe, but only for the logbook, however that requires the main control program to be running too. HRD is constantly polling the K3 of course and perhaps a rogue command is entering the stream somewhere. I am using the same prolific chipped usb adaptor that I have successfully used for years with a variety of OS's. Now using windows 7 64 bit. I can't remember if it happened on the previous XP machine. I have closed down HRD and not found the problem to re-occur, but to be honest the length of time for which I have listened without HRD running is small by comparison and the problem is sporadic to say the least. Nothing I do to HRD seems to be able to force the problem. Not Elecraft's problem I'm sure, but I am curious as to whether anyone else has noticed this issue before I venture onto the HRD forum, where they can be a little over-defensive at times :-) 73, Stephen G4SJP K3 #980 and P3, latest firmwares.

Re: [Elecraft] [KPA500]KPA500 power cord question
The electrician, either knowingly or unknowingly, did him a favor by installing the NEMA 14-30 receptacle. He can now run any amp, including the Alpha 77 series and older Henrys that use a 120V blower on the neutral. There are plenty folks who wished they had run 30A, 4-wire service from the beginning. To run the KPA500 on 240V, he only needs to use the existing 3-wire power cord from the KPA500 to the NEMA 14-30 plug, leaving the plug's neutral terminal vacant.

Re: [Elecraft] K2 KPA100 transmit test: fail
There's nothing wrong with the currents you're getting. What does your Watt/SWR meter say when you change power? Forget about how "loud" it sounds on the receiver. The econd receivers AGC could be clamping down to make the signal sound the same. I'll bet the S meter on the second receiver is going up. To do transmitter testing you need a watt meter.
