Re: [Elecraft] K3 and Mutek Transverter combo?
Well .. I just spent the weekend integrating a K3 with a set of transverters for 144/222/432MHz .. Assuming you have the KIO3 and the KXV3, it's a piece of cake. You'll have to bust open your transverter to determine whether it's been configured for split or combined IF and what drive level it's expecting (your description of the connectors tells me it can be configured either way). If it's split you'll need the KXV3, if not you can likely use the HF output connector (possibly with a switched attenuator for TX). PTT can be had on the ACC connector if you're using 0dBm IF levels, else it can be taken from the rear panel PTT OUT jack. If you need to do more complicated things, there are a few other handy open-collector outputs on ACC (like DIGOUT0 and 1) that can come to the rescue .. de w1rt/john On Mon, Jun 10, 2013 at 9:54 AM, PETER HUTCHISON peter.hutchi...@btinternet.com wrote: Hi, Bit of a long shot this but has anyone any experience of using a K3 with a Mutek transverter?

Re: [Elecraft] K3-transverter interface
I'm surprised nobody has mentioned the KRC2 .. red-headed stepchild of the Elecraft line ;) I use a KRC2 with a K2 to switch 6 microwave bands in the Jitney .. 903 through 10G. The radio displays the correct frequency with the GHz lopped off. I reprogrammed the KRC2 (no programming required, just run a commandline utility) such that it turned on 2 source and 2 sink pins per band, with another pair of source and sink which turns on for any microwave band. The outputs of the KRC2 can do a few hundred milliamps, but the total package power is probably limited to under an amp (e.g. use drivers for stuff that uses more than a few 10s of mA). I drive two 1P6T relays plus some logic and a bunch of DEMI relay boards.

It looks like I should get around +10dBm or so from the driver stage alone, which is just what I need to drive the mixers in my transverters while being low enough to prevent major damage on sequencing failure, etc. Has anyone done this and measured the output? de w1rt/john __ 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] Solutions for K2 Transverter Quirks
Add an l to the url ;) http://www.qsl.net/ve3sma/downloads.html I used Don's circuit on my low-band K2 (driving one each 50,144,222,432 XV) and an external sequencer in the Jitney .. the last step of the sequencer enables TX in the K2. Steve's solution does it in one board and doesn't require any mods to the K2, and it's relatively easy to isolate 0dBm .. I also use a filter similar to Steve's .. happened to have one of Diz's universal low-pass filters (http://kitsandparts.com/univlpfilter.php) in the kit box and built it up for 10M and that eliminated a number of weird behaviours on TX .. de w1rt/john On Mon, Nov 7, 2011 at 9:34 PM, Don Wilhelm w3...@embarqmail.com wrote: Steve, I did not have success with that link you posted - I got a 404 error. There is another solution to inhibit CW until a sequencer has completed and gives a signal back to the K2. It is my article on PTT for CW on my website www.w3fpr.com. It interrupts the keying unless the PTT signal to the K2 is present (start the sequencer with a footswitch or other switch external to the K2). Yes, the K60XV option does not like VHF RF on the coax connected to the TX jack - it interferes with the K2 power control. A low pass filter with a cutoff below 50 MHz (and above 28 MHz) cures that problem A low power in-line low pass filter works fine. The problem does not exist if the high power BNC output from the K2 is used. 73, Don W3FPR On 11/7/2011 6:17 PM, Steve Kavanagh wrote: The K2 makes quite a nice IF rig for VHF transverters, but it has a few quirks, like most rigs. I've put my solutions to two issues up at www.qsl.net/ve3sma/downloads.htm . First is a sequencer which switches the RF to the transverter to prevent it from transmitting while its internal antenna relay is switching. This deals with the lack of any way to stop the K2 from transmitting on CW when the key is pressed. The other is a bandpass filter which gets rid of most of the problems due to the high RF sensitivity of the transmit IF output circuitry to RF. These are not extensive articles, but there should be enough there for knowledgeable hams to ccopy...or get ideas for better approaches. 73, Steve VE3SMA __ 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 __ 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] OT: How to reply to a thread, and why it's important
Sorry for the spam, but I quit smoking tobacco last week and I'm in a foul mood, and this is one of my pet peeves (along with HTML mail) .. minor rant Those who use a threading mail program (Gmail is a great example) see a thread as a group of messages all clumped together to make it easy to read in context. You've probably noticed that often times a reply to a thread will show up at the top level rather than in it's sequential place in the thread .. creating a new, different thread than the original. Then some people might reply to the new thread while others reply to the original thread .. maybe yet another new thread gets created. Ever wonder why? Well, it's because some people do not use the Reply button, but rather copy/past a subject line into a new email and post that. Seems sensible at first blush, but doing so breaks threads .. bad netiquette and unnecessary to boot. The key is in the (generally invisible) mail headers. Every email has 'em, and you can make them visible in all email clients one way or another (in gmail click on the little dropdown box at the top left of any message and View Original). The headers of interest for this topic are the Message-ID, In-Reply-To and References headers. Here's some of the headers from a recent top thread message on the Elecraft list: Message-ID: [EMAIL PROTECTED] Date: Wed, 5 Mar 2008 18:08:28 -0800 (PST) To: Elecraft Reflector elecraft@mailman.qth.net From: Lee Buller [EMAIL PROTECTED] Subject: [Elecraft] K3: Stereo Speakers - What are you using?

In-Reply-To: [EMAIL PROTECTED] References: [EMAIL PROTECTED] Notice how the In-Reply-To header from Tom's reply has the Message-ID from Lee's original message? That, dear friends, is the key to threading .. and those headers are only generated when you hit the Reply button! When a user tries to get around the Reply button for whatever reason, those headers are not generated and the thread is broken.. So .. please use Reply often and responsibly, and help clean up all the broken threads.

I've got a external sequencer solution, but I got to thinking that if there's at least 50 or 100 ms delay coming out of that I could get rid of the diode on the key in connector and use the 8R to fire a driver for the T/R relay.

[Elecraft] XV mods

Antennas are short yagis spaced relatively close to each other on one mast. I've experienced failures of the PHEMT due to the large amount of RF present on the unselected transverters, whose configuration leaves the gate of the PHEMT connected to the antenna connector in that state.

[Elecraft] XV mods
sorry about that, accidentally hit send :) I don't know if others have had the issues I've had with the XV transverters, but I thought I'd report on my efforts this weekend .. I run a stack of 4 XVs driving high-power TE amps in my rover. Antennas are short yagis spaced relatively close to each other on one mast.

I suspect bandpass filters would probably eliminate the problem (I have one on the 6M station and it's not given me any problems), but space is at a premium in the rover. I decided to modify the XVs in the following fashion: I remove the jumper from the antenna connector to the pad leading to the common on K1, and attach it to the W3 pad that's connected to the NO contact, then cut the trace between the NO contact and W3 (leaving W3 and the N connector connected to the output circuitry). I short the K1 common to ground. K1's NC contact is conveniently already tied to the input circuitry, and I add W2 for split output. Cut trace to K1 coil and reroute to 12V (powered when XV selected). This repurposes K1 to short the input circuitry to ground whenever K1 is not energized (XV not selected). It's an easy mod for 6/2/222, but a bit of a PITA for 432 (W3 is under K1). I've also modified my TE amps by removing the T/R relay, and am adding external T/R after the amp. de w1rt/john ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

The KRC2 and the XVT both need most of the remaining signals, so you can connect them from the K2 to the KRC2 and the XVT in any convenient fashion. The easiest would be to cable from the K2 to the KRC2, then from the second KRC2 connector to the XVT.

Aside a number of minor things, I was mostly annoyed by the bad ripple of the IF filters too, which is not a trivial thing. They kept the filters area still at a 'very kit level' , maybe it would have been better to put some extra effort there. Another major draw back for me it was the 10Hz step tuning, which with the very tight DSP set at maybe 50Hz BW it didn't really ensure a proper operation in CW/weak signals. Yes one could eventually set the RIT as the 'fine resolution tune' but then the split function was lost and, in my case, I could not compensate the doppler anymore thus being obliged to use another rig in TX... This is just to report my practical experience, it is not my intention to bias any soul.

In combination with the transvertor it slightly outperforms my home made transceiver. I can highly recommend the radio! There are only two things that bother me: 1. The throughput gain on 28 MHz seems to be low. I made a seperate output on the rig to bring the 28 MHz signal to my Drake R7/Tr7 combination and I have obviously more signal there. This of course could influance the overall noise floor... The K2 really marvels at the lower HF-bands, but the front-end filters on 28 MHz are not that good. That is probably why the excellent strong-signal behaviour for which the K2 is well-known, is not too obvious on 28 MHz. I sometimes think about replacing the frontend filters, or to change the IF to 14 MHz. 2. The IF-filter seems to produce some ripple, as reported by another ham here on moonnet. Of course this is a killer in weak signal work! I have not noticed it myself, but heard others (PA0CHN) complain about it. It was fun building the radio during the x-mas holidays together with my youngest son. So if you are looking for a heatkit-like project, then go for it! It is a superb radio for portable work. I use it in combination with a 300W mosfet amp for MS-work and have good experiences. It is probably much better than the average portbale multi-multi band rice-boxes... I am not too sure yet if it is the best radio for weak-signal EME work. I have to do some more investigation. It is hard to judge given the fact that I have lots of urban noise, something that EVERY radio would suffer from hi! I also saw a remark about microphones.

I got a hold of a buddy of mine about 30 miles away for some on-air testing while I diddled around with SSBA/C settings.

I have now seen the light. I was deeply in to a engineering mode, where i tried to do everything according to spec. The spec on the XV144 say IF input from 28MHz to 30MHz and a output from 144-146 MHz. Then the thing need to operate in that area and the natural place for alignment would be 145MHz in the midt of the window. And being in engineering mode my thinking was that the K2 was designed to match the XV144 Now you guys brought me back to real world. Why would I run the transverter with K2 That do not do FM above 144.8, that in Denmark are the border line to the the FM area (144.8 and up.) So trying to cover most used areas for CW and SSB i should properly align at 144.3. Where the output from K2 should be at full level and no issues should be seen.

You may be able to increase the usable coverage at the expense of the maximum available output by peaking the 10 meter bandpass filter at some frequency higher than the 28.2 point that is indicated in the manual. I would suggest peaking at 28.8 or even higher if you need to achieve good power output over the entire 28.0 to 30.0 MHz. If you do that, check the maximum power output at both ends of your chosen band and try to balance the maximum available power at both ends - adjust the peaking frequency up or down to achieve good coverage over your desired range. 73, Don W3FPR -Original Message- The SSB Firmware was ok, version 1.8 so no problem there. Now i have found the issue on the K2, but not the solution. The desribed issue seen on the low power out are comming from the 28-30 Mhz. if i check indicated power by the internal powermeter it drops over the freq. with the power set for 5W i do reach 5.4 W on 28 Mhz at 29 Mhz it is 4,9, still ok but at 30 Mhz it is down at 0,3 W So trying 10 W 29 Mhz only goes to same 4.9, so a rolloff on increasing freq. are seen.

Moving along in the direction of the mostly-all-Elecraft rover station, I've completed the 50 and 144Mhz transverters and should wrap up the 222 this evening. As expected, the Elecraft transverters were enjoyable to build and worked the first time (once I corrected my jumper config screwups). I did find a small problem with my K60XV during testing .. the input coax center conductor had detached from the BNC connector. Initial tests indicate performance at least as specified (and maybe a bit better). Going to do noise figure and sensitivity testing next week, but casual beacon listening and comparison to a DEMI/TS-850 looked very promising. The physical layout is very nice also .. K8ISK and I are working on building new side panels which will attach to each of the 4 XVs and tie them into a single unit, spaced convienently to allow BNC T and barrels to connect them together (might even extend them to the K2, which would make a monolithic 160M-70cm station with the footprint of the K2). Current plans are to drive the beast to Dayton for show+tell and shakedown prior to the June test .. if it doesn't end up in the flea market it'll be at the FDIM hotel.

[Elecraft] transverter power out stability
Just finished up an XV50 over the weekend. While trying to align the thing, I noticed that the power out drifts down, slowly at first and then gaining speed, with key down. Further investigation showed that the K2 was the culprit rather than the XV. I remember some threads about power output level stability a couple years ago .. did they affect the transverter output as well? Going to troubleshoot some more this evening, but wondering if anyone else has seen this behaviour .. de john/w1rt ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 as IF for V/UHF and uW
I'd love to hear from people who have been using the K2 as an IF for v/u/micro contesting. I purchased a rover vehicle recently and I'm thinking about abandoning the riceboxes it came with and move to transverters for the low bands. Current setup has dual FT-100's, which drive TE amps for 50, 144, and 432 directly and 222 using a 28Mhz IF. The microwaves (through 10G) are all run with 144Mhz IF from an IC-706. I'm thinking a couple of K2s with some switching of control and IF so they can share a set of Elecraft xverters (hopefully including one for 432 eventually - hint, hint :) That would cover the bottom 6 bands directly .. I'm tending towards an SDR solution for the top 4 anyway that would give me a nice bandscope display.
