Re: [Elecraft] More 160 meter Elecraft MOJO

[Elecraft] BFO Cal for low pitch CW and narrow filters
I am pleased to report that K2 s/n 5853 is in the transmitter alignment phase, and all is going well. Work was interrupted for a few days because we lost power in Thursday's ice storm here in STL. The house was down to 50 deg. F, when power was finally restored. Christine at Elecraft does a superb job at stuffing those parts bags. At one point, I relied on her work to provide me with a parity check of sorts on my capacitor installation. I got suspicious when I had a 561 cap left over but was missing a 560 cap. I reviewed all the other spots that were supposed to receive a560, and sure enough I found I had made an error. I was able to remove the misplaced cap and save it too. The receiver sounds great, and compares favorably with my Ten Tec Omni 6 loaded with INRAD filters. When doing the BFO calibration, I followed the recommended settings, which I understand are based on a 600 Hz pitch. I like to use narrow filters at a 400 Hz pitch. I'd like to set up for the following filter sequence: 600, 400, 300, 150 Hz bandwidths. Is there a formula I can use to calculate the BFO frequencies I need for CW normal and reverse to get the pitch and bandwidths I want? Have others produced their own charts or lists of customized BFO settings ? I apologize if I've missed something in the manual or in the list archives. 73, Chuck NI0C ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

With XIT selected, should the readout indicate a difference in transmit frequency when the knob is turned? Readout on my K2 varies when RIT or RIT/XIT is selected but not when XIT is selected.

RE:[Elecraft] WA3WSJ: Kangaroo KX1!
Ed, if you don't find the component with the freeze mist and plan to be in that kind of chill often, maybe one of those chemical handwarmers underneath and mebbe with a cheap insulated lunch bag, or plastic 3X5 file box you can keep enuff heat rising to maintain the temp to operate. Rubbermaid makes a cheap plastic black file box for abt 50 cents that I found in the office section of Walmart. Notice: I have no afiliation with Rubbermaid or Walmart hi hi. I use one as a holder for my KX1 in shack. I notched out the lid where latch is to plug key cable in and placed a rubber spacer on back of lid to angle KX1 up for better viewing angle on shelf above my operating position. I glued no slip shelf liner on bottom of of both pieces ( top of lid) and case with it fully opened. U cud use the main part for spare batteries or whatever accessories would fit. Any way I kind of got off of the temperature subject. Hope you find it or resolve it some how.Paul WD8OJL Ed said: Hello all, Well I now have what's called a Kangaroo KX1! It hiked 2-miles up the mountain to Pulpit Rock on the AT. I setup my BW Vertical and my KX1. I then hit the tune buttons and NO POWER OUTPUT! I then put my KX1 under my shirt to warm it up. I waited about five minutes and hooked it up to my BW - full power output 4w! I had to do this every qso and make the qso short so I could keep my KX1 transmitting in the cold weather that was below freezing. So during the breaks, I was walking around with my KX1 tucked on my belly under my two shirts and two fleece jackets just like a Kangaroo thus the name Kangaroo KX1. I will troubleshoot my KX1 soon with freeze mist. I plan to first put my KX1 tuner in the CAL mode to bypass it and see if the problem is in the tuner. If not then hit the transmitter with Freeze-Mist to find the bad component. 72, Ed,WA3WSJ -- ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 XIT
Chris, What you are seeing is correct. Only when you go onto transmit will you see the effect of the XIT on the frequency readout. If you want to know exactly what frequency you will be transmitting on with XIT selected then you can select the RIT as well. Of course you need to deselect the RIT to listen on your original frequency. Hope this helps.. 73 Stewart G3RXQ On Mon, 04 Dec 2006 13:40:53 +, G3SJJ wrote: With XIT selected, should the readout indicate a difference in transmit frequency when the knob is turned?

[Elecraft] K2 XIT
It will show the offset when you actually transmit. You should engage both the RIT and XIT and then when you wiggle the offset knob, you can see the qrg change. Then release the RIT and you're back on the correct listening qrg and ready to xmit on the qrg with the desired offset. It is a pain.

RE: [Elecraft] BFO Cal for low pitch CW and narrow filters
Chuck, The full 'equation' also depends on your exact filter center IF frequency. It is better to use Spectrogram which provides a visual display of the filter passband placement, and you can set things optimally for any pitch that you desire. There are instructions within the K2 Dial Calibration article on my website http://w3fpr.qrpradio.com and also info at the Elecraft website. You can download the last freeware version of Spectrogram from Tom Hammond's website www.n0ss.com - that version has more than adequate capability for setting the K2 filters and BFO frequencies. If you want to try a 'formula', I would suggest 2 steps - to change the BFO frequencies by 200 Hz, for each CW/CWr pair of frequencies, increase the lower frequency by 0.2 kHz and decrease the higher frequency by 0.2 kHz - then as a second step - If your crystal set was marked 3.6 (the most common), do nothing, but if it was higher (3.7 or 3.8), reduce all the frequencies above by 0.1 or 0.2 kHz and if your crystal set was 3.4 or 3.5, increase all the frequencies above by 0.1 or 0.2 kHz. Even so, you may be off by up to 100 Hz since the real center frequency will vary from crystal set to crystal set - Elecraft matches the crystals to 10 Hz, and the markings on the crystal bags are only to the nearest 100 Hz. Note that you can achieve better filter passband placement with Spectrogram than with just using the frequency settings listed in the manual for this reason alone. By far, the easiest and most accurate is to use Spectrogram after you complete the K2. At the point where you can receive 10 MHz WWV, you can accurately set the 4 MHz reference oscillator and all the filters so you achieve not only proper filter settings but good dial calibration as well. My website article tells you how to achieve all that with no equipment other than a computer with a soundcard, a stereo cable to connect the K2 to the soundcard and the K2 internal frequency probe. Once you have the filter settings correct for your purposes, write down the settings in case they are ever wiped out (by a Master Reset for instance) - you can restore the correct settings quickly. 73, Don W3FPR -Original Message- The receiver sounds great, and compares favorably with my Ten Tec Omni 6 loaded with INRAD filters.

RE: [Elecraft] K2 XIT
Chris, hen the K2 is in receive, the receive frequency only is displayed. In transmit, the transmit frequency is displayed (hard to see during keying). Check the K2 manual page 94 for information on how RIT and XIT work - when XIT is on, you can see the transmit frequency during receive by also turning on RIT. I prefer to jusst use split all the time - it better matches my thinking - I find I can get confused with all the combinations, especially when trying to operate quickly. 73, Don W3FPR -Original Message- With XIT selected, should the readout indicate a difference in transmit frequency when the knob is turned?

[Elecraft] Heil Handi Mic
Greetings, all I recently acquired a Heil Handi-Mic with the HC-5 element, intending to use it with a new K2 radio (#5510). I used straight-across wiring for the configuration connector in the front panel since the Handi-Mic is equipped with a cable wired for Kenwood mikes. No resistor from pin 1 to pin 6 since the element is dynamic. The mike does work, but the output seems low -- the ALC indication barely lights the top bar, and the RF output barely shows on the louder peaks. A MH-2 mike shows a little more output, though not that much more. The over-all feeling is that the Handi-Mic has a relatively low output level and may need a preamp to work properly with the K2. The mike works about the same with either K2 here. I've noted the diagram for a mike preamp for the K2, but before I build up something like that, I'm just wondering if anybody else has tried the Handi-Mic, and what any experience has been with respect to driving the K2 with that mike. Comments, anyone? ? ? TIA, Van W1WCG K2 #2634, 5510 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K2 Problem 12 Watts Out With Power Control Fully CCW
The build for K2 ser # 5628 has been going well until I got to the Alignment and Test Part III 40 meter transmitter alignment section. Problem: With current set to 2.0 AMPS and the power control fully CCW I measured 7 watts on an external wattmeter. The internal wattmeter had NO indication. When I press the tune control with the display set for voltage and current I see 13.3 volts and 1.88 amps. The current will start to slowly rise at .02 amps per second and will reach 2.00 amps in about 10 seconds and the HI CURRENT message will appear with 7 watts output. If I set the power to .5 watts the current will start out at 1.98 amps and the 2.00 amp threshold and HI CURRENT message will appear much quicker - about 1 second. I still get 7 watts of output indicated on an external wattmeter. Setting the current to 3.00 amps and the power control fully CCW I get 12 watts out with 13.0 volts and the current starting at 2.84 amps creeping up at .02 amps per second. At around 10 seconds the HI CURRENT message will appear when 3.0 amps has been reached. Setting the power to .5 watts will cause the same thing to happen but HI CURRENT message appears quickly with 12 watts output. Additional Info: The K2 has passed all checks up to this point. I am using a Heathkit 50 ohm dummy load. Turning the power control up or down gives the indication of the desired power but has no effect. L1 and L2 gives a nice peak for 40 meters. They were very close if not right on from the 40 meter receiver test. Measuring the resistance at the collectors of finals Q7 and Q8 shows 3.7K for both transistors. The power output is being controlled by limiting the current not by the power control. The internal wattmeter gives no indication on transmit but works as an S meter on receive.

Re: [Elecraft] Heil Handi Mic
Van, The Heil HC-5 and HC-4 mic elements do produce less output than many other types of mic element, and you will find a number of Posts to the List discussing this issue. Unless these mic elements are quite close to one's mouth it does seem that a preamp is required with the K2. I use a Heil Proset Plus headset which has a boom assembly containing a HC-5 and a HC-4 which means that the mic is about 2 or 3 inches from my mouth, and I do not need a preamp to drive my K2/100 to full specified output, in fact on 40m I have to move the mic a little to avoid the ALC becoming too active. FWIW my wife says that I have a 'quiet' voice. 73, Geoff GM4ESD Frank Van Cleef W1WCG [EMAIL PROTECTED] wrote: Greetings, all I recently acquired a Heil Handi-Mic with the HC-5 element, intending to use it with a new K2 radio (#5510).

RE: [Elecraft] Heil Handi Mic
I don't have personal experience with the Heil mic, but you are describing a K2 making full power output if I understand your comments correctly. When the first (right hand) ALC bar just flickers, that means the mic is providing *more* audio than the K2 needs for full RF output and the ALC is turning down the overall transmit gain. So, if you have the POWER set for a K2 to produce 10 watts or a K2/100 to produce 100 watts, and one ALC bar flickers, more audio from the mic will do no good at all. It's important to check that at full RF power. As you turn down the power you'll see more and more ALC bars light as the level control reduces the output to match the POWER control setting. (The K2 should not be run above 10 watts on SSB to avoid unnecessary distortion, although running the power wide open on CW is FB). You also need to have whatever maximum level of compression you want to use switched On and do the test on the band where the K2 has the *least* transmit gain. That's always been 10 meters on all the K2's I've heard about and seen. If you get an ALC bar flickering under those conditions, more mic gain does nothing for you. If not, then perhaps a preamp will help. Watching your RF output, the bar associated with the maximum power should just lightly flicker unless you are using a lot of compression. Human voice has a huge average-to-peak amplitude ratio, and the peaks are very brief and infrequent compared to the rest of the spectrum. The RF bargraph display is a peak reading display so it fairly accurately indicates the very brief and infrequent voice peaks. One very simple change in the K2 that makes a large difference for mics with marginal output is to change resistor R14 on the SSB module board from the original value of 1k ohms to something between 5.6k and 10k. That resistor is across the mic input. Increasing its value raises the audio level presented to the speech compressor.

RE: [Elecraft] K2 Problem 12 Watts Out With Power Control Fully CCW
Joe, The initial problem to be solved is that there is no indication of power output being fed back to the K2 microprocessor. The most likely source is a bad solder connection and the second most likely is a misplaced component. Keep your testing periods short, ignore the high current messages for now, and proceed as follows: Start your search at RF Board diode D9 - if all is well at that point, there will be a DC voltage during transmit periods - how large it is depends on the amount of RF output, for now just be certain you have a good solid DC voltage there - anything over a volt or so will indicate that the RF Output Detector is working. Next point is on the Control Board - the VFRDET signal which appears at pin 10 of P4 - the DC voltage during transmit should be about the same as you measured at the cathode of D9. Lastly, check the VRFDET signal at the microprocessor - U6 pin 2. The voltage should be about the same as at P4 pin 10 if R12 is properly in place. Let us know where the VRFDET signal path is broken. 73, Don W3FPR -Original Message- The build for K2 ser # 5628 has been going well until I got to the Alignment and Test Part III 40 meter transmitter alignment section. Problem: With current set to 2.0 AMPS and the power control fully CCW I measured 7 watts on an external wattmeter. The internal wattmeter had NO indication. When I press the tune control with the display set for voltage and current I see 13.3 volts and 1.88 amps. The current will start to slowly rise at .02 amps per second and will reach 2.00 amps in about 10 seconds and the HI CURRENT message will appear with 7 watts output. -- No virus found in this outgoing message.

RE: [Elecraft] Heil Handi Mic
Frank, Unfortunately the Heil HC-4 and HC-5 elements have lower output than typical mics. There is one in the Handi-Mic set that should work well with the K2 - and that is the one for the Icom (Heil number HM-iC) perhaps you could arrange an exchange. In general the Icom mics use an electret element with high output level - the audio input needs of the K2 and the Icom are similar. If you do wish to retain the HC-5 element, then your best choice is to use a pre-amp. There are work-arounds such as changing the value of KSB2 R14, but IMHO, the best all-around solution is to use a pre-amp and set the pre-amp gain to provide the output needed by the K2. If I recall correctly, the proper output level is -40 dBm. 73, Don W3FPR -Original Message- I recently acquired a Heil Handi-Mic with the HC-5 element, intending to use it with a new K2 radio (#5510).

[Elecraft] KX1 Receiver Deaf
It seems not all my emails are getting through, so if this is redundant please excuse me. I built a KX1 with 3080 and tuner options. Initially I had low audio but resolved by fixing a missed solder joint. With that done, It passed the initial alignment and all seemed fine. With proper ear buds the audio level is actually a bit loud for me. Unfortunately, unless I touch the circuit board near U6 the unit is deaf. Touching the board brings the unit to life and the receive is pretty good. I've resoldered everything in the area. Also checked voltages at U6. They are ok, but about 0.5 v higher than spec'd on pins 5 and 6. I've removed the tuner ( which seems to work ) and tested. Could it be a CAP, since I'm a pretty big capacitive load? The build was fun and I'm learning a lot, but could really use someone to help me clear the cobwebs and work through this problem. Thanks in advance for any help you can offer as I'm anxious to play on the air. I don't want to operate the unit with my finger stuck on the circuit board, I might give people the wrong impression of ham rado operators. 73 de KC2MJT Nate Houck ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 XIT
Firstly thanks to everyone who answered my query, either on the Reflector or privately. I can confirm that everything that you all suggest should happen is happening. So from the RIT/XIT point there is no problem with my K2 and I was using it correctly. On rethinking this I wonder if I have another problem. I haven't had chance to do any further checks but since I had (successfully so I thought) re-aligned the K2 earlier in the day, I just wonder if I have the BFO in the wrong place, even though filters all sound good. I used Spectrogram. Scenario 1 - Hear VQ9JC on 20m and want say hello/goodbye before he leaves there. He is working split, so switching RIT on off, I find his rx freq and tap XIT. He completes a QSO so I call. No QSO. This happens several times including a policeman who says G3 Up. I sense something is wrong and stop calling. Jim has confirmed he heard me on his TX freq at a good strength but didn't want encourage a co-channel QSO. Fair enough but I was convinced I was transmitting split. Scenario 2 - Was a bit apprehensive after Scenario 1 but decided to call NO2R in ARRL 160m contest. I know I can works States on 160. Had 19 Stateside Qs in the last hour of RSGB 160m Contest recently. Nothing, even pushing my amp hard. Most unusual. This was co-channel, no split. Once is one thing but twice makes me feel there is a problem. RIT/XIT looks OK, so I think I need to do zero beat and BFO checks before I go much further.

RE: [Elecraft] K2 + spectrogram
Dohn, Download version 5.17 (the last freeware version), Use the instructions on Tom Hammond's website www.n0ss.net or the links on the Elecraft site and they will match. I hope you did not pay for that version 14.1 yet - it is much more than you need for setting the K2 filters. Of course if you have other uses for the bells and whistles, that is great, but you will have to dig the 'how to use' info out of the Spectrogram help files. Most of us have not used the updated versions of Spectrogram, so we can't help a lot there. Don W3FPR -Original Message- I was planning on using spectrogram to align my filters.

I am not clear on all parts of your operation detailed - you said switching RIT on off which is the part that is not clear to me - you must turn on RIT and tune (with the RIT knob) to the frequency you intend to transmit on - then activate XIT, and go back to the intended receive frequency by turning RIT off.

That's useful when an external mic preamp to over-driving the K2 but will keep many mics from properly driving the rig when connected without a preamp. Even so, I've noticed that several mics won't drive the K2 properly on 10 meters (where the TX gain is lowest) especially if I use any compression. That seems to be the experience of a great many operators. I use an electret element that has an output of about -64 dB. It works FB once I changed R14 to 5.6K. I considered an external preamp, but it seemed to me more efficient to reduce the unnecessary loss at the mic input rather than add external active components to make up for it.

[Elecraft] Working split (was XIT)
Hmmm ... I've never used XIT except to test it. When working DX split, I usually use both the VFO's in SPLIT mode. It takes me several moments to get it right, but it usually takes me quite awhile to break a pileup and once I have it set, the operation of the radio seems more natural to me. [Must remember to cancel SPLIT after I've copied his 5NN and sent mine, however :-) ] On a several occasions however, I've come across a station QSX up with only a little pileup, and I've searched for the guy he's working with the tuning dial. I then tap RIT, tune RIT back down to his QRG real quick and call him. It's less intuitive for me than standard SPLIT, but I can make it happen much faster. One problem with this, however is that my RIT only goes about 800 Hz either way (is that adjustable somewhere?) so his QSX has to be close to his tx freq. I guess the K2 provides options for everyone. Fred K6DGW Auburn CA CM98lw ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] KX1 Receiver Deaf
Nate, I replied to this a day or two ago, I guess you did not get it - so here is what I sent. -- The most likley problem is that you may not be getting a signal from the DDS to pin 6 of the receive mixer (U6). Does it transmit with good power? If not, check L4 and L5 with an ohmmeter to see if they are open - they are easily damaged when installing them. If it transmits, then check C3 for correct value and proper soldering. If you have an RF Probe (or can construct one), check the RF Voltage at U6 pin 6 - it should be greater than 70 mV to meet the mixer specs, but the usual amplitude is half a volt of more. 73, Don W3FPR -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of nlhouck Sent: Friday, December 01, 2006 9:25 AM To: elecraft@mailman.qth.net Subject: [Elecraft] KX1 Receiver Deaf It seems not all my emails are getting through, so if this is redundant please excuse me. I built a KX1 with 3080 and tuner options. Initially I had low audio but resolved by fixing a missed solder joint. With that done, It passed the initial alignment and all seemed fine. With proper ear buds the audio level is actually a bit loud for me. Unfortunately, unless I touch the circuit board near U6 the unit is deaf. Touching the board brings the unit to life and the receive is pretty good. I've resoldered everything in the area. Also checked voltages at U6. They are ok, but about 0.5 v higher than spec'd on pins 5 and 6. I've removed the tuner ( which seems to work ) and tested. Could it be a CAP, since I'm a pretty big capacitive load? The build was fun and I'm learning a lot, but could really use someone to help me clear the cobwebs and work through this problem. Thanks in advance for any help you can offer as I'm anxious to play on the air. I don't want to operate the unit with my finger stuck on the circuit board, I might give people the wrong impression of ham rado operators. 73 de KC2MJT Nate Houck ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] OT: What Country is 4N5Y? And Why Don't I Hear Any CWSignals?
The DXCC list and QRZ.com may not have caught up with the latest political situation. It used to be one, but as of June 2006 these are separate and independent countries.

[Elecraft] Filter Setup Questions
I'm setting up my K2/100 for RTTY, using a RigBlaster and MixW. I recently had an unrelated KPA100 problem, and Gary fixed it for me, and also totally aligned the radio [thanks Gary, that service was totally worth it, my K2 is way better than I thought, and I was pretty impressed before!]. I don't want to change anything he did, it's really perfect, except I want to adjust the BW of one of the SSB filters a little. Can I just adjust the BW in CAL FIL for that filter, and not mess with the BFO settings?I just want to make it a little wider and I really don't want to undo what Gary did with everything else. Second, are the USB and LSB filters locked together ... i.e. if I change the BW on USB, have I also changed the BW on LSB? Third, if my mark-space are normal below 15m, will they be inverted on 15m and above? I just barely understand the K2 filter things, and sometimes I have QSB in my mind. This is one of those times. (OK, maybe I don't understand the K2 filter things like I said). Fred K6DGW Auburn CA CM98lw ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] KX1 Acting Up
I recently built a KX1 and it went together smoothly with no real problems. I made a few QSO's and it seemed to work just fine. I turned it on today and it is acting up on me. I was on battery power and switched to a power supply to see if that helped, but no luck. It is a basic 20M/40M unit with no ATU in it yet. (It is sitting here half built). The symptoms are that when I turn it on I get a loud hum/buzz in the earphones for about 2 seconds and then it goes to a quiet hum/buzz. This happens whether or not there is an antenna attached or not. Also..on the LED it seems to be showing the signal strength but I cannot get the LED to change. I can press the various buttons and the VFO knob and get no change in response. The hum/buzz continues and there is no change in the LCD. I am going to take a good look at the solder joints and see if there is anything obvious. Then I will check them again. While I go through that process, does anyone have pointers on where to concentrate the efforts? The troubleshooting guide in the back seems to depend heavily on two digit codes on the LED...but I don't get one of those. Any and all help appreciated!! 73 de Keith KB3ILS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] 160M Dead on my K2
Don, The suggestions did not fix my issue. All solder joints were redone and I checked everything with a magnifier light. Relay K2 works fine. I checked it on 80m where the RX is fine. I checked the bottom of the main board and all is well there too. When I switch bands to and from 160, I can see a small blip on my old analog VM from pin 16 to GND. I see a similar blip when I turn off/on the RX antenna using pins 3 and GND. Any further thoughts? 73, Mark K2QO Quoting Don Wilhelm [EMAIL PROTECTED]: Mark, Well, if relay K1 does not switch, you will not have any output on 160 meters - but you also said that it does not receive on the Rx antenna either - so relay K2 must not be working either. That combination would point to something wrong in the relay coil circuits. Check all the soldering on pins 3, 4, and 16 of J1 and check the soldering on the header as well (that will likely require removing the heat sink from the K2. Also check pin 1 of the header and J1 (that is the signal path for the RX antenna). Check the soldering on the K160RX board at the relay pins too. You are probably looking for an unsoldered connection, or one that was not adequately heated. These connections can often work initially but develop enough oxidation to give trouble after a year or so. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 #2225 is Down
Today I turned on my K2100/KAT100 and the receiver was dead. Audio was working OK. No RF output. I stripped the KAT100 away and then the KPA100 and the problem was still there. The basic K2 indicated transmit RF output between .2 to .4 watts. The power display would randomly wander between these figures on all bands so there was no meaningful output. No receiver signals on any band. D6 anode measures 8.25V and D7 anode is 0 V. I am only at the starting point for signal tracing. It seems obvious something is down that is in common with both receiver and transmitting circuits. This K2 has been completely updated with all mods and firmware. It has all options installed including the VCOSHLDKT. I hope I will be able to find the problem without having to remove the 60 meter board. I have home brew rework eliminators, so I can remove the options if necessary. All buttons and relays work as they should and the menu works as it should. I would like to trouble shoot at the most likely place. I suspect my problem is either in the PLL synth or VCO circuit. I think it would be a stretch to find the problem in the bandpass filters or low pass filters. A plan of attack would be welcome. Thanks.

[Elecraft] W-1 Needs a Peak Hold function
Hi everybody. My little W-1 has been getting a bit of a workout around here. I think this the best piece of Elecraft test equipment yet! An option that I'd really like to see would be a peak hold indication for checking voice modulated output of my K2. Kind of a fast attack/ slow decay. For those of us without a 'scope this would seem to be just the ticket. Just a little bit of program enhancement should do it. 73s, Bob K7HBG ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] 160M Dead on my K2
Mark, If you see the blips, then the relays should be getting voltage to the coils. Since the RANT works on 80 meters, your problem may be in the 160/80 meter bandpass filter rather than the k160XV board itself (it may also be in the VFO range select area too). Check the VFO range select first - just because it is easy. Set the K2 to 1800 kHz and measure the frequency at TP1 (counter probe in TP1 and menu to CAL FCTR) - it should be very close to 6715 kHz, if it is not, then check capacitor C75 for proper value 470 pf (471) and good soldering. Then check the bandpass filter additions C13 and C14 (1200 pf [122]). If these are in place and relay K3 is working properly, you should have good 160 meter receive. Once you have 160 meter receive through the RX ANT jack, then you can move on to transmit. If it still does not work after successfully passing all the above tests, look for the problem in the toroid leads on the K160RX board. That is all I can think of at the moment. 73, Don W3FPR -Original Message- Don, The suggestions did not fix my issue. All solder joints were redone and I checked everything with a magnifier light.

Re: [Elecraft] Solder weller tips
For Weller products: I would not recommend a gun to build a Elecraft kit -- that uses printed circuit boards. The TCP series has been made for 40+ years and still in production (WTCPT current model). The PT tips for this model are interchangeable for all versions from original Weller W-TCP/WTCPL (1966/1967) to present. Iron / station works on the Curie principle (ferrous alloy plug at base of tip determines the temperature that the tip will reach). OKI/Metcal based their design on these Weller patents (but they use RF for heating). No 'idiot' knob to get confused or have someone accidentally move -- built for soldering production lines -- used by Grumman for Lunar Module and Collins for S line and general rework stations (that is where I got my first one surplus and learned how to repair them !) Plentiful, easy to repair - good tip selection. EC series ~ mid 1970s to 2002. The Electronic Control series was made for 25 years and discontinued in 2002. WES51 replaced it for an entry level station (uses the same tips) Surplus readily available. Repair on older models can be tricky - depending upon model some repair parts can be more difficult to locate. The irons for this series (EC1201 and 1302B) are still current Weller production - and available. Uses the ET series of tips -- which are also used with the WES51 entry level station. WES51 is Weller's current entry level station -- equivalent in Hakko is the model 936-12 About same price range $85 to $100 depending on where you buy. Santa (my) refurbishment sleigh is FULL .. I have all styles currently W-TCP; WTCPN; WTCPS; WTCPT(2 in boxes); a beautiful DEC1001 with 2 irons (from surface mount to boatanhor with that station) -- just finished a 2 month refurbishment session. I have parts -- if you find a broken one - and almost all of the Tech Sheets (that are in my catalog) for your DIY are on BAMA. http://bama.edebris.com/manuals/weller/ Weller (CooperTools) http://www.cooperhandtools.com/brands/electronic_applications/index.htm Weller now has a BLOG ! http://weller.blog.com/ New Weller 2007 catalog (PDF) http://www.cooperhandtools.com/brands/electronic_applications/PDFs/Final%20Weller%20Catalog.pdf So Bob, what would you like for Christmas?

Re: [Elecraft] _slightly_ off-topic re: rf probe in the K2 kit
Thanks, Don. I was thinking of the other voltage probe, though this might be useful too.
