Re: [Elecraft] Need KAT2 Help
Tom, You must obtain a low balance reading before you can do any *valid* power or SWR calibration. If you cannot null with the capacitor, there is something wrong - normally that something is associated with T1 and the other wattmeter components, but you say you have checked those. OK, the next logical step is to find out for certain whether you have a problem with the wattmeter or the L-C board. Separate the Control board from the L-C board and place a jumper from J4 pin 2 to J5 pin 15 (yes, it is a long jumper - the second pin in from the far ends). Now, with only the Control Board (you must use the ANT1 connector) - connect a dummy load and again try to balance the wattmeter - if you find that the capacitor now achieves a null, look for the problem (likely a relay) on the L-C Board -but if you still cannot null the wattmeter, take another look at T1 and its associated components. 73, Don W3FPR kg3vt...@gmail.com wrote: > Just finished assembling a KAT2 for my K2.

Re: [Elecraft] K3 Utility settings transfer
.ini files have their own problems, that's why they have long been deprecated for new application development. Raymond Chen explains why in http://blogs.msdn.com/oldnewthing/archive/2007/11/26/6523907.aspx. There are issues with the Registry as well, but it's the solution a whole lot of software authors choose for rapid hierarchal access to configuration data. If I were writing the K3 Utility with extensive library support (pick your run-time library, VBRUN, .Net, Java, RealBasic, Qt, whatever), I might have used an XML configuration file, as I did with K3 Voice. One of the constraints I accepted for the K3 Utility was a relatively small download size (currently it's just over a megabyte, and about 2/3 of that is help text and help file images), and to avoid prerequisite downloads and installation issues commonly referred to as the "DLL Hell" problem. Writing XML configuration files when things change is quite slow when compared with registry writes as controls change. YMMV for the software you write, Thom.

[Elecraft] Re： [K2] XV50 vs FT817?
Hello Tim, QRP did work sometimes with this magic band. In the past cycle, I used 5 watts and made contact between Oman and Hong Kong. Also 10 watts between Brazil and Hong Kong. Of course, QRP will need more patience and skill. I never tried K2+ XV50 on field days because it is too convenience to be carried. On the other hand, I used K2 only for HF during field day. cheers, Johnny VR2XMC 寄件人﹕ Tim O'Rourke 收件人 elecraft@mailman.qth.net 傳送日期﹕ 2009 年 9月 11 日 星期五 上午 12:16:37 主題： Re: [Elecraft] [K2] XV50 vs FT817? I would strongly disagree on several points! I have run 6 meter QRP for years and they do not call it the magic band for nothing. I have 50+ countries on 6 meter QRP at last count. I run QRP from QTH as well as mountain tops and when conditions are right you do not need more than a few watts for SSB or CW and yes most VHF contest have CW activity although not as much as I would like. As for the virtues of KXV verses the 817 I use both but the 817 is my mtn top rig even with the higher current drain I like one rig for all bands, I use a 220 5 watt xverter fron a QST article with the 817 also. The KXV's are more sensitive and have a little more output and I use them at QTH. I like the ease of switching bands and the offsets for keeping frequency easy to see. Personaly I just do not like taking my K2 and transverters mountain topping. Tim W4YN Subject: Re: [Elecraft] [K2] XV50 vs FT817? To: "Peter Wollan" , Message-ID: Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original Peter, There are no VHF CW contests, per se. There is usually some 50 MHz CW activity in the June ARRL VHF QSO party and the July CQ WW VHF contest, but this is probably about 10% or less of the activity level on SSB. DX chasing, on the other hand, is typically more fruitful on CW. But chasing 6 meter DX with QRP is an exercise in frustration. DX signal levels are simply too weak for QRP. For 6m SSB, you will want at least 100W output into a decent directional antenna to be competitive in the Low Power category of ARRL VHF (up to 200W). There are no power categories in the CQ WW, so you're competing directly against the KWs in this one. Bottom line -- Outside of extremely strong 50 MHz sporadic-E openings, "VHF" and "QRP" don't really go together that well, though some guys do seem to enjoy the challenge. For me, life is too short for 6m QRP. :-) I enjoy making QSOs too much, I guess.

[Elecraft] K3: Older Firmware File Versions Still Maintained Anywhere?

Re: [Elecraft] K3 AF/RF Mod
Paul, I like what you did. I agree. I don't use the RF gain controls much if at all. I use the AF gain controls for the main and sub receiver the most. If I remember correctly the prototype K3 had the controls the way you changed them. Will have to give some thought to making the mod. 73, N2TK, Tony -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Paul Christensen Sent: Thursday, September 10, 2009 12:28 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 AF/RF Mod Okay, I couldn't leave well enough alone... Yesterday morning, I was working a T30 station split on 40m with the K3's Sub Rx and became a bit unnerved with the manipulation of the K3's "Sub AF" control when balancing between Main and Sub receivers. Multiple quick reaches for the "balance" function on the upper Sub AF control's outer ring was causing me to accidentally come in contact with the other controls. Looking at the K3 schematic, all four controls (Main AF, Sub AF, Main RF, and Sub RF) are all 10K in value. Even when the K3's AF control furnction menu is selected for "Normal," rather than AF "Balance," a similar issue can arrise when trying to quickly balance the Main/Sub AF controls on one shaft. I removed the front panel to inspect the Front Panel PCB and thought a swap of the Sub AF and Main RF controls could be easily accomplished. Here's a "before" photo of the PCB area: http://216.229.20.37/images/K3-AF-1.jpg And the "after" wiring... http://216.229.20.37/images/K3-AF-2.jpg A hot glue gun can be used near the 5-pin header to keep the two ribbon cables from interfering with future front panel extractions and insertions. Now, the upper controls handles Main AF (inner) + Main RF/SQL (outer). The lower controls handle Sub AF/Balance (inner) and Sub RF (outer). When I engage split operations and use the Sub Rx, manipulating the balance between Main AF and Sub RF is easier with a bit less propensity to accidentally come in contact with the adjacent controls since: (1) the Main/Sub AF balance function is now on the inner concentric control and extends out further from the front panel than the outer concentric ring; and (2) the balance function is now moved to the bottom where the hand can approach the control from the bottom rather than directly in-line with the knob. If needed later for a sale, reversal of the mod is very easy. Certainly, this mod is not for everyone. However, I would think that in later PCB revisions, Elecraft could provide the option of selecting the existing format or the modified format at the time of purchase -- or to the builder who simply makes a few header pin changes during construction. Of course, the front panel legends also need changing and that's probably the biggest drawback to the mod. In my case, I will use new legends printed from a Brother 'P-Touch' printer -- printed with white lettering against black background tape. Font size and type is adjustable to match the existing legends on the K3.

Re: [Elecraft] Decoder for use with K3 and PW-1
George: I'll hazard a guess: The cable that carries the band voltage level is also used for the ALC voltage output from the PW-1 to the exciter. If you started with an ICOM transceiver and had an antenna switch such as an EX-627 plugged into the transceiver's accessory connector, you could just interpose the IC-PW1, moving the antenna switch to the amplifier's accessory connector, and add a new accessory cable from the exciter to the amplifier. It's more convenient for users to do this than to require them to manufacture a new "split" cable that supplies ALC from the PW-1 and exciter band voltage to the EX-627.

[Elecraft] Need KAT2 Help
Just finished assembling a KAT2 for my K2. When I started testing I found a problem. I only get "HI" on the display in the CALn step, where you are supposed to adjust for a reading of 000. Reducing power as low as I can go, I can get a "000" display, but as soon as I increase the power, I get "HI". I tried CALP and I did get readings that made some sense (a high value for FWD and low value for REF power) but the FWD was something like 22 watts, which seems too high. I disassembled and reveiwed the SWR bridge section, counted turns on T1, removed the link on T1 and pulled up T1 to inspect the leads and soldering. Also verified all the component values and soldering in that area. So my streak is over. Thought you just finished assembl, turned on power, and all this Elecraft stuff just worked!

Re: [Elecraft] Decoder for use with K3 and PW-1
Hi George: UNfortunately, if you look at the SCHEMATIC of the PW-1, you will see that the stepped band/data voltage (paraphrasing one of my daughters) "goes in one ear and right out the other), and is NEVER TOUCHED (internally) by the PW-1 as is passes from one ACC connector to the other... I can (I believe) still provide a copy of the relative portions of the PW-1 schematic if you wish to review it. Can't include it here due to reflector restrictions on attachments, etc. It appears that the ONLY way to get the PW-1 to actually ACT upon the K3's band data is to be able to convert it from (K3) BCD to PW-1 CI-V format. 73, Tom Hammond N0SS At 10:10 09/10/2009, gdaug...@stanford.edu wrote: >Joe wrote... > > > Unfortunately the PW-1 will only work with Icom serial > > (CI-V) data.

But maybe it doesn't work for some reason[??] If you look at the schematic or the jack board (Jack 1 Unit - page 68) in the service manual, pin 4 of the ACC-1 and ACC-2 are connected only to the Exciter 1/Exciter 1&2 switch. In the single exciter position the two jacks are connected together, in the dual exciter position the two jacks are disconnected. Neither the "stepped voltage" nor the 8V reference on pin 1 appear to be used anywhere else in the PW-1. It would be difficult for the stepped voltage to switch bands in the PW-1 if it is not connected! The only purpose of the "stepped voltage" connection appears to be as a "feed through" when connecting another Icom accessory to ACC-2. 73, ...

Re: [Elecraft] K3 Utility update for Mac?
Hi Joe, My K3 developed a problem and I had to ship it to Aptos for repair. Any further Mac development will have to wait until I get the radio back. I've already completed most of the RF Gain Cal code. Hopefully I'll have the new version of the Mac utility out within the next couple of weeks.

[Elecraft] K3 AF/RF Mod
Okay, I couldn't leave well enough alone... Yesterday morning, I was working a T30 station split on 40m with the K3's Sub Rx and became a bit unnerved with the manipulation of the K3's "Sub AF" control when balancing between Main and Sub receivers. Multiple quick reaches for the "balance" function on the upper Sub AF control's outer ring was causing me to accidentally come in contact with the other controls. Looking at the K3 schematic, all four controls (Main AF, Sub AF, Main RF, and Sub RF) are all 10K in value. Even when the K3's AF control furnction menu is selected for "Normal," rather than AF "Balance," a similar issue can arrise when trying to quickly balance the Main/Sub AF controls on one shaft. I removed the front panel to inspect the Front Panel PCB and thought a swap of the Sub AF and Main RF controls could be easily accomplished. Here's a "before" photo of the PCB area: http://216.229.20.37/images/K3-AF-1.jpg And the "after" wiring... http://216.229.20.37/images/K3-AF-2.jpg A hot glue gun can be used near the 5-pin header to keep the two ribbon cables from interfering with future front panel extractions and insertions. Now, the upper controls handles Main AF (inner) + Main RF/SQL (outer). The lower controls handle Sub AF/Balance (inner) and Sub RF (outer). When I engage split operations and use the Sub Rx, manipulating the balance between Main AF and Sub RF is easier with a bit less propensity to accidentally come in contact with the adjacent controls since: (1) the Main/Sub AF balance function is now on the inner concentric control and extends out further from the front panel than the outer concentric ring; and (2) the balance function is now moved to the bottom where the hand can approach the control from the bottom rather than directly in-line with the knob. If needed later for a sale, reversal of the mod is very easy. Certainly, this mod is not for everyone. However, I would think that in later PCB revisions, Elecraft could provide the option of selecting the existing format or the modified format at the time of purchase -- or to the builder who simply makes a few header pin changes during construction. Of course, the front panel legends also need changing and that's probably the biggest drawback to the mod. In my case, I will use new legends printed from a Brother 'P-Touch' printer -- printed with white lettering against black background tape. Font size and type is adjustable to match the existing legends on the K3.

Re: [Elecraft] [K2] XV50 vs FT817?
I would strongly disagree on several points! I have run 6 meter QRP for years and they do not call it the magic band for nothing. I have 50+ countries on 6 meter QRP at last count. I run QRP from QTH as well as mountain tops and when conditions are right you do not need more than a few watts for SSB or CW and yes most VHF contest have CW activity although not as much as I would like. As for the virtues of KXV verses the 817 I use both but the 817 is my mtn top rig even with the higher current drain I like one rig for all bands, I use a 220 5 watt xverter fron a QST article with the 817 also. The KXV's are more sensitive and have a little more output and I use them at QTH. I like the ease of switching bands and the offsets for keeping frequency easy to see. Personaly I just do not like taking my K2 and transverters mountain topping. Tim W4YN Subject: Re: [Elecraft] [K2] XV50 vs FT817? To: "Peter Wollan" , Message-ID: Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original Peter, There are no VHF CW contests, per se. There is usually some 50 MHz CW activity in the June ARRL VHF QSO party and the July CQ WW VHF contest, but this is probably about 10% or less of the activity level on SSB. DX chasing, on the other hand, is typically more fruitful on CW. But chasing 6 meter DX with QRP is an exercise in frustration. DX signal levels are simply too weak for QRP. For 6m SSB, you will want at least 100W output into a decent directional antenna to be competitive in the Low Power category of ARRL VHF (up to 200W). There are no power categories in the CQ WW, so you're competing directly against the KWs in this one. Bottom line -- Outside of extremely strong 50 MHz sporadic-E openings, "VHF" and "QRP" don't really go together that well, though some guys do seem to enjoy the challenge. For me, life is too short for 6m QRP. :-) I enjoy making QSOs too much, I guess.

You can use the registry editor (regedit) to export the registry key HKEY_CURRENT_USER/Software/Elecraft/K3 Utility to a .reg file, copy the file to the other machine and import it there. I would examine the .reg file with anotepad before importing it for reasonableness. The reg file should contain only keys and values for the key named above.

Re: [Elecraft] Is beta 3.30 audio-blast free??
Hi Allan, Back on Sept 6 & 7, there were a couple of reports of it still happening on 3.30. Personally, I haven't heard it, but that doesn't mean anything. I've been avoiding headphone use for the time being. A while back (FW 2.67), they added the CONFIG:AF LIM setting intended for use when AGC was turned off. I wonder if turning this on would help limit the blast if/when it occurs? 73 -- Joe KB8AP On Sep 10, 2009, at 7:14 AM, Allan Taylor wrote: > The question is: is the beta 3.30 firmware free of the rare but > potentially damaging earphone audio blast > problem??

Re: [Elecraft] Is beta 3.30 audio-blast free??
If Elecraft thought they could guarantee that, there would be a new version out there right now. Just remember it's *beta* software. As always YMMV. This is the alternative to releasing firmware changes only in new model radios that cost kilobucks. Everyone gets to choose whether they want to play in Elecraft's "kitchen" or not. Not everybody enjoys the heat or getting flour on their pants. Doesn't bother me to come out of the kitchen with my hair singed and looking like I got the flour jar dumped on me. But I love this kind of stuff. That's *my* choice. May you enjoy yours. As to the issue itself, software problems like that are always [expletive deleted]. I've chased after hundreds of nasty apparently intermittent software problems over my IT career, and it never gets any better. My inner emotional patience with the Aptos folks on this is based on my complete identification with the frustration of finding such. 73, Guy.

[Elecraft] T1 Antenna tuner
Hi all. Been playing around with my T1 and have a few questions and thoughts... First, I think that it is the best of the automatice QRP tuners out there. I bought mine ready-built, but I'm thinking of getting another as a kit so I can at least say that I've built it. Now the questions- 1) I plan to use mine in the attic to tune a horizontal loop. Do I need the 1:1 / 4:1 balun? 2) Has anyone thought about combining the T1 with the Buddipole...would it even be necessary...and would you again need the balun? I could envision the T1 right at the center tee just like they use the triple-ratio balun now. 3) I would like to make a suggestion for the firmware. Maybe after a tuning session, the system can be set to automatically send out the information. (maybe turned on/off somehow if not in use otherwise) I will be using my T1 up in the attic and can't get up there all the time. A remote display/assessment of the situation would be great...especially via a little box with a PIC and LCD display. I'm not sure how many others use the T1 in a more permanant setup but this might be something to think of. - Mike KB3ELW __ 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
