[Elecraft] KRX3 aux protection: good idea?
Hello folks My KRX3's carrier operated relay is rattling when I have an RX loop connected to its aux input when I transmit on 160/80. Too much antennas on a too small lot. Nah, Whadda ya gonna do? As a quick fix I used an A/B antenna switching relay to open the RX chain when TXing. Loop on input A and switch to unconnected input B with PTT. But this QRO relay is very noisy to have it clicking away in the shack. With the box on the desk, I even feel it switching. So I'm going to make a silent dedicated solution for it. Would the following idea have any side effects or negative consequences? I'm planning to use a DPDT relay as follows: when in RX: NC contact in series to pass the signal, NO contact parallel over the input when in TX: NC contact in series opens and blocks the signal, NO parallel over the input closes thus the RX is short circuited to GND. Or would a 50ohm resistor over the input be better than a pure short (seen somewhere on the web)? Would this work? I can't see why not. Would any other stuff be needed or recommended (diodes, caps, MOV?) for RX protection? All input appreciated.

Re: [Elecraft] 472KHz transverter for KX3
Tim, I see two main options... 1. Transverter is 'dumb' and is just there attached to the KX3 and no controls (other than basic T/R) come from KX3 to Transverter and you live with a display that is 'offset' by the IF. or 2. Transverter works with the KX3 menus for Transverters (see the XV etal series) and some of these might be used. From a use perspective I suspect it might be 'nice' to have the display read 473KHz etc or whatever frequency you are on and not 28.473 so the offset looks like a minimum and might the selection of the transverter band etc. I note that the KX3 does not have a low power output so either there would have to be a manual check that the output power (into the transverter) is only 0.1W (default) still to define the best level or there needs to be an intelligent(?) sense that advises that the power is too high and does not damage it. The menu option XVn PWR sets this. 72 Dom M1KTA On 24/01/13 10:10, Tim Hague wrote: Dominic please keep us updated, interesting.

Re: [Elecraft] 472KHz transverter for KX3
Hi Dom, I suppose being an 'old boy' I've been used to transverters that are dumb, I just learnt to ignore the MHz read outs and substituted the correct figures in my head!. I have the K3 as well as the KX3 and have just fitted the transverter output option which gives me 1mW to drive a box.

Re: [Elecraft] 472KHz transverter for KX3
The transverters may be dumb, but the KX3 and the K3 both have the smarts to display the output frequency - anywhere between 0 and 24999 MHz. Just use the XVn RF menu to set the low end of the transverter output band. 73, Don W3FPR On 1/24/2013 8:30 AM, Tim Hague wrote: Hi Dom, I suppose being an 'old boy' I've been used to transverters that are dumb, I just learnt to ignore the MHz read outs and substituted the correct figures in my head!.

Re: [Elecraft] 472KHz transverter for KX3
Thanks Don, Yes agreed I just advised was looking at two options. I had already been sent an email asking was this limited to KX3 only? The answer would be no hence the dumb option. UK has 472KHz-479KHz available to full licencees with a Notice of variation to the licence. The option equates to either operate with the KX3 in the 'normal band' with no frequency feedback so you will need to know what the transverter LO is set to and you need to be sure you set the output power low or I believe you can set it to a transverter band and then a couple of options become available, being the IF and the frequency display (as you say). The RF out is also dropped to 0.1W by default. A quick test seemed to show the RF out was c0.1W no matter what the normal power level was set to but was a really quick test before had to run as got normal day job. 72 Dom M1KTA On 24/01/13 13:41, Don Wilhelm wrote: The transverters may be dumb, but the KX3 and the K3 both have the smarts to display the output frequency - anywhere between 0 and 24999 MHz.

[Elecraft] [K3] Integration and Increasing complexity
My shack is getting increasingly complex and with my K3 I plan to once again attempt to get the remoterig working once and for all. At the moment I have the MicroHam microkeyer 2 integrated with my Steppir three element antenna interfacing with my K3. It is a nice setup. The ACC plug is shared with a Y connector between my Microkeyer 2 and the Quadra. When I use 6m I usually unplug the Microkeyer to swap out for the preamp. Adding the remoterig soon means that some of the same audio connectors and rs232 connectors need to be shared. The number of connection points and potential share points is increasing. Is there any commercial product that would be able to cleanly and efficiently provide seamless and simple integration of my increasingly complex shack and be able to integrate all these components. I also plan to eventually add the KPA500 and KAT500 to this same K3. Any assistance or recommendations on this would be greatly appreciated.

[Elecraft] K3 Receiver
Good morning everyone from snowy, frigid Michigan... I have K3 SN# 52XX and the receive seems to come and go on 30 mts - that's where I notice it the most but it happens on other bands too. My AGC settings are: AGC DLY - NORM AGC HLD - 0 AGC PLS - NORM AGC SLP - 4 AGC THR - 12 AGC F - 120 AGC S - 20 For example, the S-meter will be reading an S3 noise level and I can see it on the P3. Suddenly, the noise levels drops to zero and the P3 follows. If I'm listening to a CW signal, that signal drops too. If I hit the keyer and send a dit, the receive comes back. I've noticed this on a few of the other bands too. I am running the latest firmware and software but I've noticed it on the previous versions too. Ideas??? Thanks.

Re: [Elecraft] K3 Receiver
Perhaps your problem is external to the K3. Are there any normally-open relays between the K3 and the antenna? I had this same issue happen to me several times in a December contest. I suspected the problem may have been a dry circuit issue in the AL-1500 T/R relay. Since then, there have been two low-power contests in January and, for those, I bypassed the AL-1500 (rerouted the coax). The problem did not recur in either one of those contests, despite thousand of T/R cycles on the K3. It looks like my suspicion regarding the AL-1500 was correct. I will dry-clean that relay before the next high power contest.

Re: [Elecraft] K3; using QuickMix software.
Thanks to all who contributed. Good suggestions. I went to the website below, and it looks promising. There is a mention of Vista and Windows7 administrator problems but there is a work-around. I will try this later. In the meantime, I played with right clicking the QuickMix icon and clicked on 'troubleshoot compatibility'. It was a bit confusing, but it eventually automatically chose Windows XP service pack 2. It gave me an incompatible message of sorts, but ended up working. One thing confusing is when I right click on the Icon in the desktop, it shows an icon of a shield in front of Run as administrator. But in the properties/compatibility, it does not have administrator checked under Privilege Level, so I think it will be a winner. I'm glad to get this resolved for Windows 7 use.

[Elecraft] KPA 100 Resistance Checks
I thought the following observations may be of help to anyone having difficulty achieving the KPA 100 resistance measurements on page 44 of Rev H of the KPA 100 manual. I initially performed the checks using a DMM with the PCB illuminated by a 40 Watt bench light a few inches away. Resistance values were very variable and only Q1 and Q2 base measurements were within specification. The other measurements were too low in value and would ramp up and down, with the DMM sometimes indicating a minus resistance value (whatever this meant!). The orientation of all relevant diodes and transistors was checked to no avail, and then I happened to switch off the bench light and hey presto, everything worked properly with all values easily within specification. The two PA transistors appear to be photo sensitive and must produce photo electric currents similar in magnitude to the DMM test current. If I perform the checks with my moving coil multimeter (2000 ohms/volt), the correct resistance readings are achieved with or without the bench lamp on. DMMs are very useful but care has to be taken in understanding the results!

Re: [Elecraft] [K3] Integration and Increasing complexity
I am wondering if the MicroHam station master or station master deluxe would work. Any thoughts? Thanks, Keith AK6ZZ Sent from my iPhone please excuse typos On Jan 24, 2013, at 6:11 AM, Keith Heimbold ag...@hotmail.com wrote: My shack is getting increasingly complex and with my K3 I plan to once again attempt to get the remoterig working once and for all. At the moment I have the MicroHam microkeyer 2 integrated with my Steppir three element antenna interfacing with my K3. It is a nice setup. The ACC plug is shared with a Y connector between my Microkeyer 2 and the Quadra. When I use 6m I usually unplug the Microkeyer to swap out for the preamp. Adding the remoterig soon means that some of the same audio connectors and rs232 connectors need to be shared. The number of connection points and potential share points is increasing. Is there any commercial product that would be able to cleanly and efficiently provide seamless and simple integration of my increasingly complex shack and be able to integrate all these components. I also plan to eventually add the KPA500 and KAT500 to this same K3. Any assistance or recommendations on this would be greatly appreciated.

[Elecraft] KX3 AGC *PLS
Using SSB, in this mode PLS makes the AGC seem very fast and is very annoying particularly when band noise and static is high. Is this normal?

Re: [Elecraft] [K3] Integration and Increasing complexity
I've been using a Station Master since soon after they were introduced and I highly recommend it. It will do all kinds of switching jobs, primarily for controlling antennas, but I think it also will control your Quadra from a dedicated PA control port. I know it can control the SteppIR by communicating directly with the controller in native communications protocol via the Data Out on one of the older controllers. I actually have a pair of Station Masters, one for each station, and I built a special purpose circuit that steers the appropriate SM data lines to the antenna with a lockout mechanism to only let one radio at a time control the antenna. One really nice SM feature is that with a small optional PS2 keypad you can select antennas, rotate your antenna and control the SteppIR modes with a few keystrokes without having to touch the control panel. I'd suggest you download the Station Master manual and have a look at it. Since you're already running Router with the MK II there's very little installation required; just creating the necessary new virtual COM ports. The SM will show up as a new tab in Router. Pretty much anything you can think of that involves controlling antennas and their selection can be done with proper configuration. The Station Master Deluxe is a nuclear-grade custom control solution for huge multi-multi type stations. You won't come close to needing one of them. 73...

[Elecraft] KPA500 240V wiring
I assume from the schematics for 240V operation, the KPA500 is wired across the two 120V legs to create the 240V (with no return line). I understand the safety wire is another lead. __ 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

The other side of 240 V IS the return line. Neutral is NOT used for 240V equipment. Neutral WOULD be necessary if the equipment also needed 120V to operate, but ONLY if that was the case, and a 4-wire plug would be required. I understand the safety wire is another lead. Yes, and it's the green wire and goes to the chassis. __ 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] 472KHz transverter for KX3
Dave (and a couple others commented similarly) This is probably why I suggested two options 1. dumb so not 'integration' so the dial you will have to do the math... and 2. then when the software catches up (a few other things appear to be missing still like SSB DVR) perhaps can have a display that says 472KHz etc rather than the IF. Either way should hopefully not change the construction of the transverter it does mean that I may need to be aware of the IF choices that KX3 might use. If a 10MHz or some other frequency for an LO is available great if not, I am already building an LO for use anyway and I could make it switchable IF Elecraft do provide it later. I have 472KHz available now so cannot wait for 18 months for a software update from Elecraft, if it were open source maybe I could add it? 72 Dom M1KTA On 24/01/13 17:42, WW2R Elecraft wrote: It would make the maths even easier if one could set XVn IF to 10MHz (and XVn RF to 0MHz), one could then use the K3 external 10MHz reference as the Transverter Local oscillator Last time I checked Wayne was working on the software to give the KX3 the same xverter driving capabilities that the K3 already has Dave WW2R Date: Thu, 24 Jan 2013 08:41:36 -0500 From: Don Wilhelm w3...@embarqmail.com To: elecraft@mailman.qth.net Subject: Re: [Elecraft] 472KHz transverter for KX3 Message-ID: 51013a10.5050...@embarqmail.com Content-Type: text/plain; charset=ISO-8859-1; format=flowed The transverters may be dumb, but the KX3 and the K3 both have the smarts to display the output frequency - anywhere between 0 and 24999 MHz.
