Re: [Elecraft] K-1 4-band Availability/Status?
This mainly for Jay, W6CJ. Don answered your question about the availability of the K-1 4 band module. That is a shame as it really made the K-1 more versatile. I am really enjoying mine. You also asked about the stability of the K-1's VFO. I had not heard of any issues before buying mine and haven't had any problems. There is a small drift when first turned on, but stabilizes within a short time (minutes). If you had a signal within the bandpass, it will not drift outside the bandpass during warmup. After the rig has been on a few minutes you will not notice any drift. Of course this is only my experience.

Re: [Elecraft] K-1 4-band Availability/Status?
There is probably some middle ground here to satisfy most people in this situation. It's completely understandable and correct that Elecraft would not want to spend the effort to re-engineer this board. However some of us on channel don't see the task as rocket science and in most cases would be glad to provide that expertise as a side effort just to make that equipment useful. If Elecraft had even something as simple as unpopulated boards to purchase for use as prototypes, it would make that task quite simple. Dr. William J.

[Elecraft] 4band K1
Yep, I bought a used K1 based on the Elecraft website which still has the 4 band board listed. After I bought the rig I realized there was no price on the order form for the 4 band board. I wrote an email to Elecraft Sales and was told some of the parts for that board became scarce so no more. My suggestion would be to remove the board feom the website entirely. However, its my second K1 and I intend to hang on to it. Now I just need to decide what to build to pick up a few more bands. Yeah, I know but I already built two K2s and a K3 so I'm aiming a little lower this time.

I assembled K3 serial# 8887 (FW-5.14) so far succesful but have a problem with the SUB RX and diversity. I plugged the coax from the BNC AUX-RX into the KRX3 at assembly time. When I switch on the SUB RX it gets its antenna input from there, which I can verify by plugging out the antenna connected to BNC AUX-RX and do not hear anymore the signals received before. So the connection between the antenna connected to AUX-RX and the KRX3 is already established and working. ! When I now, while SUB is active, press and hold SUB, the diversity ! mode is established and the decimal point of VFO A starts blinking, ! I hear a relay switching noise out of the K3 and the signal received ! by the SUB-RX before went off. So it looks to me as if the KRX3 is disconnected from my receiving antenna by switching from SUB to SUB-diversity. What gets switched at this moment and why? Switching on diversity should only bind/link the SUB RX to VFO A (the same as pressing A-B after changing frequency) but phase coupled this time, or I am totally wrong? Switching between Config:KRX3 ATU and AUX makes on difference, and no relay clicking is audible. Can anyone with a newer K3 (and new syntesizers) tell me if he is oberserving the same behavior?

Re: [Elecraft] Useful P3 feature
Yep, that would be cool, although I'm not sure it's doable. Would likely work if you were switching bands often, but if you don't come back to a band in a reasonable time, the average may be as invalid as REF LVL currently is. I generally take K9YC's advice if it pertains to audio, sometimes I'm a little slower on non-audio things. Jim runs P3 spectrum averaging as high as it will go. I never did ... fascination with the jumping spectrum display? I'm currently running at 12 for the spectrum and OFF for the WF and the WF is what I look at and I like the results. I find I don't have to adjust the REF LVL nearly as much. Having found out that 12 is safe for averaging, I may push it up. But, seriously, to my surprise, it really does tend to hold the REF LVL much more constant which is what I was looking for in the first place. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 3/6/2015 4:56 AM, Vic Rosenthal 4X6GP/K2VCO wrote: I don't want to save the REF LVL.

Because I use my Heil headset with several different (in Field Days etc) I have had to confront the problem of different vendors using different microphone connectors - and even worse, the same connector with different pinoutsmy solution was to wire the microphone plug to the Yaesu standard - with apologies for using the Y word on the Elecraft list :-) - , set the headers in the MFJ to the Yaesu standard (and also the appropriate header to apply the polarising voltage to the electret microphone insert), and then build individual Yaesu - Elecraft, Yaesu - Icom etc. adapters for rigs that don't use the Yaesu pinouts. I'm afraid I don't know where you can buy pre-made cables, but making up the adapters is straightforward if a bit fiddly. I don't know if that will help in your particular situation (I suspect perhaps not), but on the principle that any info might come in useful I thought I'd chip in. 73, Quin G3WRR From: pastor...@verizon.net pastor...@verizon.net To: elecraft@mailman.qth.net Sent: Wednesday, 25 February 2015, 4:05 Subject: [Elecraft] MFJ 434B Connections Hi, this is Mark Griffin, KB3Z. Has anyone connected a MFJ 434B Voice Keyer to the K3? I assume that I would connect my Heil HM-12 microphone to the external microphone jack on the front of the unit. The man from MFJ said I would have to set up the jumpers in the unit for a Kenwood. But for some oddball reason they use a modular cable plug to connect the 434B to my K3. I realize I would have to use the MIC Connector on the back of my K3 and would have to make the necessary change with the K3 so it knows that I am using the MIC connector in the back. But where do I find one of these Modular cables to connect the 434B to the K3. Any help or advice would be very much appreciated.

[Elecraft] K3 SUB-RX works , but not in diversity mode
SUB-RX works (gets signals) but not in diversity mode. I assembled K3 serial# 8887 (FW-5.14) so far succesful but have a problem with the SUB RX and diversity. I plugged the coax from the BNC AUX-RX into the KRX3 at assembly time. When I switch on the SUB RX it gets its antenna input from there, which I can verify by plugging out the antenna connected to BNC AUX-RX and do not hear anymore the signals received before. So the connection between the antenna connected to AUX-RX and the KRX3 is already established and working. ! When I now, while SUB is active, press and hold SUB, the diversity ! mode is established and the decimal point of VFO A starts blinking, ! I hear a relay switching noise out of the K3 and the signal received ! by the SUB-RX before went off. So it looks to me as if the KRX3 is disconnected from my receiving antenna by switching from SUB to SUB-diversity. What gets switched at this moment and why? Switching on diversity should only bind/link the SUB RX to VFO A (the same as pressing A-B after changing frequency) but phase coupled this time, or I am totally wrong? Switching between Config:KRX3 ATU and AUX makes on difference, and no relay clicking is audible. Can anyone with a newer K3 (and new syntesizers) tell me if he is oberserving the same behavior? I am not quite shure if I have overlooked something at assembly time or if this is a firmware bug. -- 73, Klaus, DF1TL __ 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] Useful P3 feature
Here is something I would like to see on the P3. The P3 saves the REF LVL setting per band. But of course the noise level on a given band varies as conditions change, and I find myself often adjusting the REF LVL. The optimum setting is with the REF LVL just below the noise level. Setting it higher loses detail, and setting it lower fills the waterfall with noise. What I would like would be to adjust the REF LVL to optimum with respect to the noise level and then save this relationship. Then I would like to be able to push a function button to automatically adjust the REF LVL to re-establish the same relationship. This would make the readjustment, which I find myself making every few minutes sometimes, much quicker and easier. I don't want to save the REF LVL. I want to save its relationship to the noise level. -- 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ __ 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] K-1 4-band Availability/Status?
Jay, Yes, the KFL1-4 is no longer available. Take a look at the K1 specifications to be certain the frequency stability is sufficient for your needs. Yes, there is some drift as is common in any analog VFO (and the K1 uses an analog VFO). The frequency determining capacitors are either polystyrene or NP0 disc ceramics which have good (but not perfect) temperature stability. If the VFO inductor is carefully wound with the turns tight to the core and it is properly secured, the K1 VFO frequency stability will be better than specifications. I have dealt with 2 or 3 K1s with drift outside the spec limits, and they were 'cured' by properly winding the inductor and/or replacing the poly capacitors. Most of the K1s that I repair have frequency stability well within the specs. 73, Don W3FPR On 3/6/2015 4:25 PM, J wrote: I was interested in building a K-1 4-band, but learned the 4-band boards are unavailable.

Re: [Elecraft] K-1 4-band Availability/Status?
Hi all, The KFL1-4 module needs trimmers that are both wide range and extremely temperature stable, due to the high loaded Q of the band-pass filters. To emulate this stable capacitance with trimmers now available, you'd have to use a hand-selected C0G cap in parallel with a much smaller trimmer for each of the original 16 trimmers. This would be extremely tedious for builders. So, while it is possible, it is not practical.

Ross, That vital part is the availability of the 1 to 40pF trimmer capacitors - which also had a very tight temperature compensation characteristic. The KFL1-4 used 16 of them. Due to their wide capacity range, the same capacitors could be used in all 16 positions and provide successful tuning. Those capacitors have been discontinued by the manufacturer. The problem is that there are no substitutes that could be used for all 16 positions, and it would take a great deal of engineering effort to determine the suitable substitutes for each position on the 4 band board. In other words, would a 3 to 15pf trimmer be suitable in the C1 thru C4 locations and would a 12 to 30pF trimmer be suitable in the C5 thru C8 locations and so forth. Furthermore, if the 17 meter band were chosen instead of the 15 meter band, which low range trimmer capacitors would be used for each band. I am speaking of examples for the engineering effort that would be required to select the best capacitor for each position and each band choice. It is not a trivial exercise. I certainly would not want to do experiments to select the appropriate replacement trimmers necessary to resurrect the 4 band board, and I am certain the engineering staff does not have the time to do that work. The documentation would get more complicated as well - for example, if you have chosen the 15 meter band, use the red trimmer capacitors at location Cx but if you have chosen 17 meters, use the yellow trimmers at those locations Hopefully you get the point of the complexity created by those wide range trimmer being no longer available.

Re: [Elecraft] K-3 BCB DX setup advice request.
Tim, As you tune around the AM broadcast band you will want to keep in mind this excellent paper by Jack Smith, K8ZOA: http://www.cliftonlaboratories.com/peak_and_average_agc_and_am_mode.htm . The end result of these measurements is that you should disable the K3's AGC while listening to AM BC. It sounds so much better. Jack answered a nagging question I had had for years concerning why AM BC sounded so poor on ham receivers, and now I know why.

[Elecraft] 50W TX Gain Calibration Bug
Hi All, I just installed the 5.14 in my K3 and when I ran the 5 and 50 watt TX calibration I kept getting Calibration power settled at 3.495.72; and it would abort. It appears that during this calibration procedure VFO B is being used. When it got to 80 meters it would abort. My VFO B was set to 3495.72, which is out of band and being out of band I do not think the transmitter will transmit RF power. This caused the abort. Perhaps the Calibration software should set the VFOs in band before preforming the calibration. Once the VFO was set in band all is well.

Re: [Elecraft] 50W TX Gain Calibration Bug
If that's a real problem, install 5.10, do the calibration then move on to 5.14. You only need to do the 50 W cal once, they say.

Re: [Elecraft] K-1 4-band Availability/Status?
The part number for the bare KFL1-4 board is E100129 as listed in the KFL1-4 manual. I do not know whether Elecraft has any boards in stock, but one could ask. Good luck with your project(s). You would also need the firmware E610010 as well as the other parts such as relays, connectors, crystals etc. If you downloaded the KFL1-4 manual before it was removed, you are 'in luck'. 73, Don W3FPR On 3/6/2015 10:03 PM, Dr. William J. Schmidt, II wrote: There is probably some middle ground here to satisfy most people in this situation. It's completely understandable and correct that Elecraft would not want to spend the effort to re-engineer this board. However some of us on channel don't see the task as rocket science and in most cases would be glad to provide that expertise as a side effort just to make that equipment useful. If Elecraft had even something as simple as unpopulated boards to purchase for use as prototypes, it would make that task quite simple. Dr. William J.

Ross, That vital part is the availability of the 1 to 40pF trimmer capacitors - which also had a very tight temperature compensation characteristic. The KFL1-4 used 16 of them. Due to their wide capacity range, the same capacitors could be used in all 16 positions and provide successful tuning. Those capacitors have been discontinued by the manufacturer. The problem is that there are no substitutes that could be used for all 16 positions, and it would take a great deal of engineering effort to determine the suitable substitutes for each position on the 4 band board. In other words, would a 3 to 15pf trimmer be suitable in the C1 thru C4 locations and would a 12 to 30pF trimmer be suitable in the C5 thru C8 locations and so forth. Furthermore, if the 17 meter band were chosen instead of the 15 meter band, which low range trimmer capacitors would be used for each band. I am speaking of examples for the engineering effort that would be required to select the best capacitor for each position and each band choice. It is not a trivial exercise. I certainly would not want to do experiments to select the appropriate replacement trimmers necessary to resurrect the 4 band board, and I am certain the engineering staff does not have the time to do that work. The documentation would get more complicated as well - for example, if you have chosen the 15 meter band, use the red trimmer capacitors at location Cx but if you have chosen 17 meters, use the yellow trimmers at those locations Hopefully you get the point of the complexity created by those wide range trimmer being no longer available. The values I have proposed above are only numbers off the top of my head for examples, they have no value in the real world. 73, Don W3FPR On 3/6/2015 6:46 PM, Ross Primrose wrote: Looking at the parts list, I can't imagine which part is no longer available 73, Ross N4RP On 3/6/2015 4:37 PM, Phil Wheeler wrote: Confirm.

Re: [Elecraft] Back in time question
I'd also suggest an analogue volt meter, as they are generally better when adjusting for minimum and maximum voltages. And, although rather obvious, an antenna able to receive a transmission with good frequency accuracy. I used the Elecraft noise generator, a dummy load, a digital multimeter, Spectrogram, and a wire antenna. I subsequently obtained a 50kopv analogue meter and used it to refine some of the settings. Incidentally, I don't understand how the subject summarises the question. -- David Woolley Owner K2 06123 On 04/03/15 18:27, Don Wilhelm wrote: A dummy load and a DMM are sufficient - just follow the instructions in the manual. The K1 and the K2 both include provisions for reading the internal frequencies as well as other built-in tools. Of course there are other tools that can be helpful - Spectrogram is useful for providing a visual display of the filters, especially on the K2.

Re: [Elecraft] KX3 external battery (Maxtron) VERY NOISY
Yeah it is an oxy moron sometimes... operate off grid using a battery and you get noise (this will be the internal LiION battery recharging/regulation circuitry causing it). Have you tried adding ferrite to the DC leads (and weirdly to the headset leads, I need to if using ext battery sometimes). You could make up a simple choke and plug your rig power lead into that, doesn't need to be in a box or anything... leads from battery then 12 turns of the power leads or so in opposite directions in parallel on the ferrite (try FT240-61) to a set of connections to the rig. Or a string of those little 5mm ID clip on ferrites (ebay) on the Elecraft lead. 72 Dom M1KTA Owner of #1082 #2334 On 06/03/15 04:53, Robert Sands wrote: A reflector poster mentioned the Maxtron MX 160A for use with the KX3.
