[Elecraft] K1 Backlight Kit Insulator Card
I have finally started to install this kit as I needed to pop the rig open to fix a problem and wonder if I'm missing a part. When I opened the plastic envelope, I have four parts: 2 resistors, the LCD display, and the Backlight (with pins A & K). According to the parts list, I should have a 5th part called Insulator Card Assembly #E850215 which, according to step #14, includes double-sided foam tape. There is a small piece of masking tape on the Backlight itself. Methinks I'm missing this Insulator card, right? 73, Clark WU4B (x-KE4RQ) -- View this message in context: http://elecraft.365791.n2.nabble.com/K1-Backlight-Kit-Insulator-Card-tp5346426p5346426.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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: Flakey PA Output
I guess I should have been a little more explicit in my trouble shooting. The problem of power dropping to zero was on all bands which seemed to eliminate the filter board. The problem had happened once a year or so ago when I posted a question relating to "Lo Po" display (I have the KAT2) but then seemed to go away. Hmmm. The DC voltages checked out fine. Using the rf probe, I found rf (with values a whole lot higher than those listed in the manual) up to the base of Q6 using the TUNE function and/or a straight key for key down. There was at times some output on the collector of Q6 but would quickly drop to zero. That's why I posted my question late at night (my eyes and brain were turning to mush) about the failure rate of Q6. The next day I reheated the solder joints for all components around Q6 and output returned. R50 value measures okay. A closer visual on the toroids indicates I may have to remove them and retreat the leads. Thanks to Don and Gary for their suggestions. I think I'm on the right track to fix this intermittant. If I get it solved by Dayton, I just might purchase another option for my K2 (thinking about the transverter option) while "she" is on the operating table. 73, Clark KE4RQ K2 # -- View this message in context: http://n2.nabble.com/K2-Flakey-PA-Output-tp4725896p4736619.html Sent from the [K2] mailing list archive at Nabble.com. __ 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] K2: Flakey PA Output
Was operating the ARRL CW contest and output on my K2 QRP rig dropped to zero. Bummer. Anyway, I took it to the bench and started to check it out when it began to work. Put it back together and took it to the operation position and it failed. I'm thinking a cold solder joint or something. Tonight I stared signal tracing and found the output of Q6 to be zero under key down after a few seconds. I as about to order a new Q6 and it started working again. I've been poking around, pushing this component and that one, hoping to find an intermittent but with no success. Could Q6 be failing internally--that is the little beastie is going bad not because of a solder joint (which I have reheated) but because of something inside? Is there another component in the driver circuitry or PA that could be causing this? I really wanted to use the K2 this weekend for the QRPARCI contest but may have to rein in my big rig. Your comments and suggestions are greatly appreciated. 73 de Clark KE4RQ -- View this message in context: http://n2.nabble.com/K2-Flakey-PA-Output-tp4725896p4725896.html Sent from the [K2] mailing list archive at Nabble.com. __ 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 KUSB PROBLEM
Hi, Julian. Yes, I changed the Stop Bit on the USB to Serial Port to 1 and set the speed to 4800 baud. I can find nowhere in HRD where the Stop Bits can be set or changed; am I overlooking something? At the K2 end there is no flexibility in settings (unless there is a hidden menu I'm not aware of). Results: N1MM works; Logger32 works; HRD doesn't work. I'm running Windows XP with all the latest patches. There is something not right in HRD and I'm thinking it is between my OS and HRD because HRD is solid and in use by 1000's of hams. I just can't imagine what is amiss but will continue to try and remedy it so I can HRD. 73 de Clark KE4RQ From: Julian, G4ILO [via Elecraft] [mailto:ml-node+4542423-1391773...@n2.nabble.com] Sent: Tuesday, February 09, 2010 12:12 PM To: Clark Macaulay KE4RQ Subject: Re: K2 KUSB PROBLEM Did you try 1 stop bit in the COM port settings? I think the K2 manual says 2 stop bits but I have had problems using 2 stop bits that went away when I changed to 1. The double flash probably means the data is being fragnmented. I wouldn't have thought HRD would assume that a response from the radio would never be broken in the middle, because Simon is a professional programmer and knows what he is doing.

Re: [Elecraft] K2 KUSB PROBLEM
N1MM works fine. Logger32 works fine. HRD doesn’t work. I know HRD is solid piece of code and is in use by many people with Elecraft rigs. I’m inclined to think there is a setting somewhere in HRD that is amiss but I can’t figure out where that might be. There is very limited control of the COMM port offered to the user. Or maybe there’s something amiss between HRD and Windows XP.

Re: [Elecraft] K2 KUSB PROBLEM
Thanks, Guy. What’s so interesting is that one of the converters has the Prolific chipset and works fine with Logger32 but won’t work with HRD.

I have had the same problem. It is most annoying to see the K2 picture (ain't she pretty!) on the HRD webpage and not get mine to work with my XP machine over the serial-to-USB converter. After a lot of tests, I have concluded that there is something amiss in the converter and the HRD software. Why? The same converter/k2/cpu combo works fine with Logger32. I've tried 2 different chipset converters with the same results.

One other test: on another computer using a REAL RS-232 interface, HRD and my K2 act like a happily married couple. I know this test changes two variables but it is an interesting data point. So, I've stopped trying to figure it out and will be content to use Logger32 instead of HRD until such a time that the shack computer can have a REAL RS-232.

Re: [Elecraft] K2 RTTY
I've decided to take the plunge into digital modes and 'found' the RTTY mode (and extra set of filters) in the SEC menu. There is still much about my 1 year old K2 that I'm still finding out. What a radio! When I went in to set the filters in RTTY mode and decided to check the SSB filters as well. Using Spectogram, I cannot ajust anything to make the 300 cycle point at -60 db down. I CAN adjust it such that it is -60 db down at 2500 hz. There appears to be no low frequency roll-off at all. Adusting the BFO moves the high frequency point; it does not move the low frequency point. My setup: K2# 6110. AF option is OFF and switched out of the circuit. I'm using the External Speaker Output to drive the sound card. I don't see this porblem with the CW filters. Is this normal? Received SSB signals sound fine. 73, Clark KE4RQ Don Wilhelm-3 wrote: > > JT, > > There is nothing wrong with AFSK - in fact, if the carrier balance on > the KSB2 board is adjusted correctly, AFSK is indistinguishable from FSK. > > The only 'problem' with the K2 is that the BFO range is limited, with > the result that narrow filters cannot be set with a center frequency > equal to the 'true RTTY' tones.
