[Elecraft] W2 Watt Meter firmware load?
I recently put my K line station together K3S, KAT500, KPA500, P3. They are all working great! I have added a brand new W2 watt meter. It came with version 1.0 firmware which from what I understand has not changed in many years and is the latest version. I was testing my new W2 watt meter and it does not seem to go into firmware load mode. I hold both the on button and sensor button while powering the W2 on. I do not get the left blinking light as the manual states. What am I doing wrong? I would like the firmware load mode to work in the event I need to reload firmware. I am able to send commands to the W2 with my computer. Any help would be appreciated.

[Elecraft] KPA500 / KAT500 and W2 watt meter question
I just ordered the KPA500/KAT500 combo and W2 watt meter for my K3S. Should I use the key line interrupt connected to the W2 watt meter or should I connect the key line interrupt to the KAT500? Do I even need to use key line interrupt with the K line set up?

[Elecraft] KPA100 no output above 11 watts
I just finished putting a KPA100 kit together. All the initial tests were satisfactory until I got to the point where it is time to check the output of the PA above 11 watts. When I set my K2 above 11 watts I get a High Current message with no power out. I set CAL current to 3.5 amps. I set the CAL current to 4 amps with the same issue. The K2 works with the amp connected at power levels below 11 watts. Where do I start looking? I have looked around T1 and components per the manual. The component values are correct.

Re: [Elecraft] Help with troubleshooting K2 receiver?
I found my problem. I left C158 out some how. I now have signal and the 7. birdie.I am able to peak L1 and L2 without the slugs bottomed out in the cans. I do have a concern The highest I can get L30 to adjust to is 5.5 volts with the slug in L30 all the way to the bottom of the can. I am using a battery with a voltage of 12.5 volts. I am using a Fluke model 87 meter to take the voltage readings. I went back through and checked all component values and orientations as if I was starting over building the receiver section. All component values are correct as well as orientation. T5 is wound with 16 counted turns on 1-2 and 4 turns on 2-4. It looks exactly as the diagram. Here are my VCO voltages: 80m 3500 2.23v 4000 5.5v 40m 7000 1.887v 7300 3.63v 30m 1 3.11v 10150 3.67v 20m 14000 2.607v 15000 4.31v 17m 18000 3.196 18200 3.396v 15m 21000 2.349 21450 3.47 12m 24800 4.26v 25000 4.66v 10m 28000 3.372v 28800 4.22v Do I have a problem or is this acceptable?

[Elecraft] Help with troubleshooting K2 receiver?
I have my K2 built to the second alignment step. It passed all the tests on the first part of the build on initial power up. My K2 is not hearing the 7. birdie. I am not hearing anything on 40 meters from receive signals with an outside antenna connected or my broad band generator connected to the antenna connector. The PLL linearization worked fine with no errors and the end message showed up when it was finished. I do hear the signal at J15 C6 on the left side as viewed looking down from the top of my K2. I get a small signal increase when I inject my broadband signal generator to the top of the case of Q21. I get an increase in signal on pins 3 and 4 of the K1 relay. No increase on any other pins when the 40 meter band is selected. I get a signal increase at jumper W5 and W2. I get a small increase at W1. I get a small increase on both sides of D6 diode. I get an increase at the case of Q22. I have tripled checked component orientation and values, cold solder joints. I am able to get the pre amp and attenuator to work when I inject the signal at W5. I am able to get all the freq readings on the BFO and filters adjust fine. The cans for L1 and L2 have the big slots no marks. I had to adjust them bottomed out and then got a slight signal increase. It is almost as if the cans a for L1 and L2 are not the proper value. I was only able to get 5.5 volts out of L30 with the slug all the to the bottom. All of the VCO voltages came out with in specs. 1.887 volts being the lowest on 40 meters at 7. L25 and L26 are wound correctly and have good continuity between the pads. Where should I start looking for a problem ? Thanks, Glenn WA7SPY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Need Help with K2 build
I recently purchased a new K2 to replace my older one that I sold a while ago. I am to the first power up test stage. Everything checks out normal except when I go to measure the 4.0 freq on the control board at the left side of C22. I get all 00s. I have checked the freq probe for shorts and all is normal. I removed the heat shrink and checked the coax to the capacitor and it checks good as well as checking good at the solder joints on the back side of of P6. I even tried to measure the freq at pin 14 on U6 and get all 0s. I checked X2 for shorts to ground and none were found as well as shorts between the crystal leads and none were found. I have continuity to pin 14 to C22 on U6. The freq probe does work when I touch my finger on the tip. I am suspecting a bad component Where do I look? Can I continue to the next build stage?

[Elecraft] Resolve to K2 failing first test
I feel very stupid as an experienced kit builder I made a rookie mistake. I could not get the K2 to power up at all. I checked and rechecked everything. I ended up taking my old working K2 s/n323 apart and started swapping things around. The control board was good in my K2. My front panel worked fine on the rf board of the K2 being built. The new front panel did not power up my K2. Ha the problem is in the front panel board. I started looking around. What do you know U2 is upside down. Thank God I have a Hakko 808 desoldering tool! I removed U2 installed it the correct orientation. The K2 now passed all initial tests. Never a dull moment! stupid stupid stupid! Thanks for your input Don Glenn Maclean WA7SPY Don Wilhelm wrote: Glenn, While it certainly does sound like your 7805 regulator has gone 'belly up' (you said it clicked relays at first and then stopped), I would revisit the resistance readings at the output pin of U5 as a first order of business.

Can I unplug the control board and power up the 5 volt regulator by applying 13 volts to the input to the 5 volt regulator with the control board un-plugged without hurting anything? I suspect the 5 volt regulator is defective or something else is dragging the voltage down. The 5 volt regulator is verified as a L7805 installed.

Bill Johnson wrote: Bill WHAT are the changes to R11 and R30 Everyone is referring to them, but no-one has said what they are!! Must be a dark secret, Grif. Nobody seems to want to tell, apparently least of all the folks who report having performed the mods! A small difference in power isn't worth consideration vs the importance of a clean signal. A change from 4 w to 2 w is only 3 db which is not notable for audio difference. Thus some of us who have owned for the entire time haven't paid any long lasting attention. I have never operated any QRP rig at it's full power. The reduced power has a huge advantage in battery life and has little to no impact on the receiving station's ability to copy.

Glenn Maclean WA7SPY Sacramento, CA Here is what Gary at Elecraft had to say. I went by his guide lines. 33 ohms worked well in my case. Your milage may very. Yes it is OK to change R30 do not go any more than 47 ohms. (See below) Hi All; Here is the comments from Gary at Elecraft concerning the Low Power conidition of the KX-1. Those output levels are typical and are pretty normal. You will only get 3-4w if 13.8 to 14.0VDC is used, and the load is a good 50 ohm non-reactive match. The KX1 is not designed to produce 4-5w (or more) like the K1 can, as it has a much simpler transmitter and is optimized for mainly portable and battery use. If all parts are correct, you can safely increase R30 at the base of the PA transistor Q6, but not more than 33-47 ohms or increased spurious output will result. 33 ohms would be a good first value to try. -- 73, Gary AB7MY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Station grounding question
I recently up graded my house electrical panel from 100 to 200 amp service. In order to do the up grade I had to install a Ufer ground which was 20 feet of bare #4 copper wire in cement. Our local code allowed a 10 foot run of wire in a U shape in a 9 inch wide trench. The wire had to be 3 inches above the dirt 3 inches from the side of the dirt 3 inches between the wires and three inches away from the dirt on the other side of the trench. That allows for 3 inches of cement all around the bare copper wire. The more I found out about Ufer grounds the better they seem to be to me. The PH factor in the cement and the fact that the cement never completely dries out and retains moisture make it an excellent ground. This leads me to my question. Is anyone out there using a Ufer ground as a counterpoise or to ground their tower and station? This seems way better than the old ground rod pounded in the dirt. Any comments would be appreciated.

[Elecraft] SSB and M-2 microphone
I want to say the combination of doing the 2.4 Khz cap mod, and replacing the crystals on the RF board and SSB adapter( my ssb adapter board was one of the very first ones to come out)and receiving a MD2 microphone for Christmas is a winning combination. Having a Hakko 908 de-soldering tool made replacing the caps and crystals a snap. I am getting unsolicited compliments on the audio quality since doing the cap mod. With the QSO's I have been having lately the folks do not believe I am running a K2/100. Prior to doing the SSB cap mod I was using a MH2 hand microphone. I was always getting reports of bassy transmit audio even after replacing the crystals and using spectrogram to align the ssb filters. I think the MH2 microphone will sound great now as well after doing the cap mod. I need to do some comparisons with the two microphones to tell for sure, If you have an older ssb adapter I highly recommend doing the cap mod. A big thank you to Elecraft and Bob Heil for making the K2 a great SSB rig! Happy New year!

[Elecraft] SMD Version of the K6XX Visible LED CW Tuning Indicator
I received my tuning indicator from Tom Hammond N0SS last week. I put it together on Sunday. To my dismay it did not work. I checked and tripled checked component placement and wiring. It all looked good. I still could not get the tuning indicator to work. Tom and I emailed back and forth. I was about ready to send my board to Tom for his evaluation. I got home from work tonight and started trouble shooting. I got out my trusty Hakko 808. I put the small long tip on it. I cleaned up all the solder off of all the components. I then touched up all the solder connections to all of the components. I plugged the board back into the K2. What do you know the 10th LED now lights up when the tuning is locked on a signal. I can adjust the LED to come on and off with the trim pot. If anyone else is having problems make sure you have good solder joints! Especially the little legs to the very tiny FSK chip which is the heart of the tuning indicator circuit. They are hard to see let alone solder. Make sure you have a very small soldering tip and you get in and out quickly with the tip so you do not over heat components or lift a trace. Tom did an awesome job with this little project! I hope this may help someone else who has or may have problems with this SMD kit.

[Elecraft] Need help trouble shooting a K1
Hi guys, I am helping a friend trouble shoot a K1 that he just finished putting together. This is a 2 band 40/20 meter K1. The 40 meter band is working perfect with a full 7 watts output into a 50 ohm dummy load. The power output can be adjusted up and down while in transmit on 40 meters. The 20 meter band has a problem. It will only put out 3.5 watts and once the power is set all the way up you can not adjust it back down while in transmit. The power can be adjusted up and down while in transmit on 40 meters. I have used an RF probe on the filter board and here are the voltages I am getting: RF Filter Board voltages using a RF probe 20Mtrs40Mtrs P1-4 Premix oscillator signal 200-500mVpp 192mV 561mV P1-6 Premix signal output signal 55mV 800mV P2-1 TX Buffer output 1-3Vpp 740mV 880mV P2-8 Filter board TX output to driver 1-3Vpp 624mV1.7V P3-1 PA output up to 40-55Vpp 14V 19.8V P3-8 Output from lowpass filter 40-55Vpp 13.59V 18.78V The voltages are shown as to what should be expected using an O scope which I do not have. The RF probe readings will be 35% or so less than what an O scope will show according to Gary. I have verified the toroids and actually rewound them all and made sure the leads were properly tinned and reinstalled them. Where do I look for the problem? I am also guessing the problem is on the Filter board and not the RF board due to the fact the 40 meter portion is working as advertised. The 20 meter crystal on the filter board was also replaced due to being suspect. I am guessing a bad capacitor? Any help would be appreciated.
