[Elecraft] K2 #5723 is alive but got a few problems
Hello all Well, k2 5723 is alive, but I have a few snags. First, No smoke, and about 10 watts +\- on all bands except 40m. no output on 40. Display says " high current " and shows no rf output on meter on 40 m. but I was stupid and handled a plug for the cw key over the rig without the cover. Blew the fuse on the power line when the plug dropped onto the board and I think took out one of the PA transistors, the one closest to the back of the rig. Replaced the fuse, On all other bands, I can get 5 to 6 watts MAX out on all bands except 40m. still no rf output. Also, all bands now give the hi current message on the display. I am learning as I go here so could someone please explain how I can confirm if one of the Pa transistors is bad? Looking for suggestions and procedure.

RE: [Elecraft] [K3] Unanswered Questions ...
OK, that brings me back to the original question ... since the standard 2.7 KHz, 5-pole filter is 2900 Hz at -6dB which should be wide enough on receive for AM (by shifting the receive passband to use one sideband) and for ESSB (except for the ultra fidelity group), is there any harm in using the FM filter for AM and ESSB transmit? If one wants maximum performance on AM/ESSB receive, I understand the 6 KHz filter will provide better IF image rejection (now I'm really interested in the FM filter curves - including the stopband and ultimate rejection specification). However, if the priorities are maximum performance on SSB and CW (including protection from AGC pumping), a slight (?) reduction image rejection due to the wider filter may be an acceptable compromise given the limited number of available filer "slots". What is the ultimate rejection in the 8-pole filters, the on-line curves only go to -80 dB? Some of the filters (250, 400, 1.8K) show signs of "flaring out" at 70 to 75 dB down and for others (6K, 2.8K) the scale is wide enough that the skirts are "off screen" before they reach -80 dB. Of course, this may all be academic when variable width filters are available. 73, ...

In FM mode, capture effect helps suppress the effect of "image" leakage.

AM and (E)SSB modes have far more dynamic range and the > 15 kHz IF image must be suppressed by some 10s of dB more than is > required for excellent FM operation. Are you speaking of receive performance or transmit performance? The conversion "image" either transmit or receive is separated from the desired frequency by twice the IF (in this case 15 KHz). In this case the "image" would be 30 KHz away - in this case at 8.245 MHz (or 8.185 MHz depending whether the second LO was above or below the IF). Since the specifications for the KFL3B-FM are not available, the closest filter I can find is the 15 KHz wide, 7.0075 MHz, 6-pole INRAD "front end" filter. That filter shows a estimated shape factor of 2.1 (1/60 dB). Assuming the desired signal is centered in the first IF (roofing) filter passband and we were dealing with a 6 KHz wide ESSB signal, the closest "image" frequency would be 27 KHz from the center of the "roofing" filter. At 27 KHz from center, the response of that 15 KHz/6-pole filter is down 80 to 100 dB depending on the filter's ultimate rejection - remember, the filter is 30 KHz wide at the -60 dB point which is 15 KHz from the center of the passband. If we're looking at an AM signal with 5 KHz audio response, the nearest component is 25 KHz from the center of the filter - again down far more than 80 dB (and another 6 dB down compared to the PEP of the transmitted signal). It would seem to me that 70 to 80 dB suppression of the transmit image is far more than required by Part 97.307(d) ... and that something in the .01 mW PEP range for 1500 W PEP of "desired" signal would be more than acceptable. Is there something in the digital domain that I'm missing - aliasing, artifacts, etc. that effects this? Now, on receive 80 or 90 dB may not be sufficient rejection, it depends on conditions but still at nearly two times the -60 dB point on the filter skirt it would seem that the image response would be determined by be more one of circuit leakage and the filter's ultimate (stopband rejection) rather than skirt selectivity. Has the IF image response been checked with an engineering sample or prototype of the KFL3B-FM in either receive or transmit? 73, ...

Re: [Elecraft] [K3] Unanswered Questions ...
Hello Joe! Unlike most DSP-based radios, the K3 converts from the main IF (8.215 MHz) to the 15 kHz DSP IF without an intervening 455 kHz IF. This helps give the K3 a cleaner sound and better dynamic range since there are fewer conversions. However, this also means the IF crystal filter must have exceptional skirt selectivity to prevent the 15 kHz "image" from getting through. In FM mode, capture effect helps suppress the effect of "image" leakage. AM and (E)SSB modes have far more dynamic range and the 15 kHz IF image must be suppressed by some 10s of dB more than is required for excellent FM operation. It is for this reason that the FM filter is recommended only for FM use. It may also be used for AM receive, but is not recommended for AM transmit. The 6 kHz filter has the necessary 15 kHz IF image rejection to be suitable for use with either AM or (E)SSB. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Re: K3 & KRC2
Darrell; Nice suggestions. The best way to see what triggers the KRC2 can handle is to view the KIO2 command set. Whenever one of the parameters changes, and is reported out the serial port, the KRC2 picks it up, creating an internal event. The KRC2 personality will then determine whether that event does anything. The standard personality does just a few things (mostly just band changes), while the KRC2ACC personality makes use of most of the parameters. Note that for the KRC2 to see these events, it must be connected to the KRC2's serial IO and be set to use that data. See the KRC2 manual for jumper settings for serial mode. There are some problems inherent with a couple of the items you list involving availability of the information. For example, if the K2 control processor does not find a KAT-2 or KAT-100, it will not allow any further processing that requires those devices. Thus when you hit the ANT button on the front panel, it doesn't even try to communicate with the ATU, but simply puts up the LCD error message and goes on. Thus the KRC2 doesn't see anything that would tell it to do something. I believe the RXAnt selector behaves the same way, depending on the K160 module being present. However, if the 160 meter module is present, the RxAnt selector is a trigger for the KRC2, and it can make decisions based on RxAnt being switched on or off. The use of this trigger is not included in the standard KRC2 personality. As for the tune button, I don't believe it causes anything to be sent out on the serial port, which means the KRC2 cannot be triggered from it. This would be a great addition, but would require changes in the K2 program memory, something we probably won't be seeing for a while. It seems the engineer is a bit busy with other things at this time... ;-) If you have other suggestions or requests, give me a shout directly and we can discuss them.

Sense the receive antenna menu option, even without the K160 module, and sink or source outputs based on the state of this menu option. 3. Allow the tune button on the K2, to lower power and the KRC2 to put out a tune signal to an external antenna tuner. 73, Darrell On Tuesday 23 October 2007 07:42, Jack Brindle wrote: The outputs can be controlled from a wide array of triggers, not just band selection. -- Darrell Bellerive Amateur Radio Stations VA7TO and VE7CLA Grand Forks, British Columbia, Canada ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Why is that, does the DSP modulation process require additional filtering to make it acceptable on transmit? If so, how "bad" is the unfiltered signal? Since the KFL3B-FM is not likely to be any wider than the typical four pole "roofing filter" in most of the "modern" transceivers, one would think that AM receive performance would be good to excellent with just the DSP filtering. In that case it would seem to be silly to "waste" one filter filter slot if one wanted to configure a K3 for both FM and AM (or ESSB) transmission. If both the KFL3B-FM and KFL3A-6K are required, it means the user must make a choice between equipping the receiver with normal and narrow roofing (first IF) filters for both SSB and CW or "all mode" (FM, AM, and ESSB) operation. 73, ...

[Elecraft] Videos
Hi all, It would be nice to have more videos of the K3 on youtube.com, I have recently learned about these radios and would like to see more of it. Right now there are only two videos regarding the K3, one from Dayton and the other from the Tokyo Ham fair. We need more for those of us poor souls who have to conformed with the cookie cutter japanese radios.

Re: [Elecraft] Re: K3 & KRC2
Please list what other triggers there are. My wishlist for the KRC2 and K2: 1. Sense the Ant 1/2 switch on the K2, even when no Elecraft tuner is installed or connected, and sink or source outputs based on the state of this switch. 2. Sense the receive antenna menu option, even without the K160 module, and sink or source outputs based on the state of this menu option. 3. Allow the tune button on the K2, to lower power and the KRC2 to put out a tune signal to an external antenna tuner. 73, Darrell On Tuesday 23 October 2007 07:42, Jack Brindle wrote: >The outputs can be controlled > from a wide array of triggers, not just band selection. -- Darrell Bellerive Amateur Radio Stations VA7TO and VE7CLA Grand Forks, British Columbia, Canada ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] [K3] Unanswered Questions ...
I have not been able to find answers to these two questions in the archives, in the K3 FAQ or on the Elecraft web site. 1) What is the bandwidth of the KFL3B-FM filter at -6 dB and -60 dB? 2) If the KFL3B-FM is installed in a K3 (when available) is a separate AM filter required for AM and/or ESSB transmit? In other words, is the requirement simply that one roofing filter be of sufficient bandwidth to pass the AM/ESSB or is the "proper" bandwidth required to clean up artifacts from the DSP modulation process? 73, ...

[Elecraft] Polar Bear QRP Hunt!
Hello, Please join the hunt for Polar Bears! On Saturday, October 27th, 2007 we start yet another Polar Bear Moonlight Madness Event Season. QRPers known as Polar Bears will go out into the Full moon night and operate our QRP radios. This is really a fun event and all QSOs are not contest-type QSOs, but raw chews! To find out more about this unique event, go to the EPA QRP Club's Polar Bear Site. http://www.n3epa.org/Pages/PolarBear.htm For this first PBMME of the season, the four "founding bears" will be operating from Pulpit Rock on the Appalachian Trail in Pennsylvania. Some will drive up the mountain while others will hike the 2.5 miles to the summit. I'll hike to the summit so why not give me a qso for the effort! Most of the polar bears will setup in a large field on the summit known as the Lehigh Valley Amateur Astronomical Society Site. http://www.lvaas.net/index.html?content=pulpit Why not bag a Polar Bear Saturday night during the hunt? 72, Roo Bear Ed, WA3WSJ PB # 2 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] proposal: why not design a monoband CW/SSB QRP TRX
I wouldn't mind seeing an Elecraft 40M SSB/CW rig (since it would almost certainly be stable enough for PSK31 and AFSK RTTY, too). But take a look at the MMR-40 from Hendricks QRP Kits. It can be used as-is, or with the NorCal FCC-1 or with the FCC-1 and -2 combination. Or you can use a Small Wonder Labs FreqMite for a frequency readout. I picked up one within 30 minutes of picking up my K3, since the K3 is a little large to use for a motorcycle rig, and I want SSB capability. I'll use the FreqMite, myself. The Sierra is a CW rig, and I think the request included SSB. Note that the Cascade, a 20/75M SSB rig, was modified to a 17/40M version, but it wasn't stable enough for my purposes. (Wow, that was 12 years ago!!) 73, doug Date: Wed, 24 Oct 2007 12:27:33 -0400 From: Brett gazdzinski <[EMAIL PROTECTED]> Thread-index: AcgWVl6Wldg2elkMTiOjgcn2Tp7pkAAA3sNQ What about a sierra with a 40 meter plug in?

[Elecraft] Re:Elecraft K2 Two problems
Brian (GM3AKF) writes ... Why when I remove the KDSP2 does the audio disappear? Brian, Referring to the upper right corner of this diagram ... http://www.unpcbs.com/common/images/diagram_large.png the audio chain in a stock K2 is routed through jumper wires CTRL-R18 and R19. However, these jumpers are removed when CTRL-J1 and J2 are installed in preparation for the installation of the DSP. You can use your K2 without the KDSP2 by jumpering from CTRL-J1-1 to CTRL- J2-1 and from CTRL-J1-2 to CTRL-J2-2, i.e. from pin 1 on J2 to pin 1 on J2 and from pin 2 on J1 to pin 2 on J2.

Re: [Elecraft] proposal: why not design a monoband CW/SSB QRP TRX
I had all QSOs on 40 m. 40 m is where the action is, day and night. Others might favor other bands. But I would fancy a great monoband transceiver. More than a decade after the Norcal 40 A, I bet Wayne can amaze us all again! 72, Chris Hs0zfe = I agree about 40 meters. I have often said that I could do about 90% of my operating with my Norcal 40A. But I disagree about the need for a new 40M monoband design. The simple analog design makes it a delight to use. No digital quantum jumps in the tuning. No operation manual or cheat sheet needed. The only change for home use would be to use the K2 mixer design and this would more than double the cost as it involves more than just subbing a TUF mixer. Compare the two designs. The power consumption would increase considerably. Mods to customize for user preference are easy. I like to use multiturn tuning pots like the K1 uses. But I still have a K3 on order. 73 Rick Dettinger K7MW My rigs and raisins come from Aptos, CA. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I converted my shack and a couple op positions at our club shack to APP's - soldered dozens of them, works great. One tip: make sure of the orientation of the connector pins before soldering especially on heavy gauge wire. This can be a bit tricky as the pin will want to rotate on the wire as soon as you touch it with the soldering iron (Murphy at work). It's important so you don't have to twist the conductor to get the pin into the connector. Also the little APP insertion tool is quite handy for small gauge wire. So now we know, there are two solder connections on the K3 kit!

Re: [Elecraft] K3: supplied power cable specs?
I use Power Poles for all my 12 volt gear: radio power, chargers, other electronic gadgets, and have always soldered the pins on. I have never had a failure in years of using them. One small benefit of soldering, for those of us cheapskates, is that they can be used again for other purposes. Just release from the plastic housing with a jeweler's screwdriver, unsolder, and resolder onto another application. I use the same little screwdriver to push the pin into the housing, but watch your fingers!

Re: [Elecraft] K3: supplied power cable specs?
Unless I'm mistaken, aren't the PPs on the the cable when you receive it anyway (I don't remember seeing anything about assembling them in the manual)? I confirm soldering works great, just be careful to get a good flow of molten solder, but not enough to run out of the contact end and onto the actual wiping contact. For what its worth, I have converted all my 12v power to use PPs, I even took the Molex connector off the Yaesu FT-857 and replaced with PP (why didn't I do what a lot of people have done and put PPs on the fly lead? Because the Molex connector had an intermittent connection, not to mention it being about twice the size). To this end, I bought a West Mountain Pro crimper from Quicksilver Radio Products (http://www.qsradio.com/, I found them to be very good) because I had so many to do.

Re: [Elecraft] K3: supplied power cable specs?
but.. the K3 is a no solder kit! Sorry... I converted my shack and a couple op positions at our club shack to APP's - soldered dozens of them, works great. One tip: make sure of the orientation of the connector pins before soldering especially on heavy gauge wire. This can be a bit tricky as the pin will want to rotate on the wire as soon as you touch it with the soldering iron (Murphy at work). It's important so you don't have to twist the conductor to get the pin into the connector. Also the little APP insertion tool is quite handy for small gauge wire. So now we know, there are two solder connections on the K3 kit! (Four if you count the PL-259) 73, BillN2BC - Original Message - From: "Tom Hammond" <[EMAIL PROTECTED]> To: "Darwin, Keith" <[EMAIL PROTECTED]>; Sent: Wednesday, October 24, 2007 8:34 AM Subject: RE: [Elecraft] K3: supplied power cable specs?

Tape over the rear accessory holes might keep insects out, but it will not keep rodents out...They've got teeth, this coming from someone who knows because they got into a bagged, stored air conditioner and built a smelly nest...A dummy connector or a blank metal plate made from flashing would be my choice...Flashing can be cut with scissors...

Re: [Elecraft] K3: supplied power cable specs?
Powerwerx (http://www.powerwerx.com/) sells an inexpensive tool for locking the connector into its housing. This tool can also be used to remove a connector from the housing. I have one of the crimp tools sold by Powerwerx (http://www.powerwerx.com/product.asp?ProdID=3324&CtgID=1022) and it works much better than the less expensive tool also from that company. With the TRIcrimp, I get perfect crimps every time. Sometimes difficulty in getting the contact into the housing is caused by a slight bend in the contact (the less expensive crimper tended to do this) or a slight out of round in the crimped body of the contact. I have not so far soldered the contacts on, but do plead guilty to putting a ratchet tie around the figure eight cable just before it enters the housing and filling the void in the housing with hot glue and extending the hot glue up to the ratchet tie. The purpose is to prevent repeated bending of the cable near the contact. Maybe this is not good practice. I don't know. FWIW. Usual disclaimers. 73 Kevin VK3DAP / ZL2DAP Dave Martin wrote: Oh No! Instead of toroids, I have to build power pole connectors! Is there a Power Pole Guy out there? :-) I don't care what they say, I solder mine like I do almost all my crimp connectors. I've never had one melt out or fail. Now to get the little jasper snapped into the housing.

[Elecraft] proposal: why not design a monoband CW/SSB QRP TRX
In Fall 2002, I had some fun with a K1 and a dipole which almost touched the grass. A rotten CW beginner, I had all QSOs on 40 m. 40 m is where the action is, day and night. Others might favor other bands. But I would fancy a great monoband transceiver. More than a decade after the Norcal 40 A, I bet Wayne can amaze us all again! 72, Chris Hs0zfe ___ Want ideas for reducing your carbon footprint? Visit Yahoo!
