[Elecraft] Let me build your K2
I have built more than 170 K2's. Let me build your radio. My prices are reasonable and you end up with a finished radio ready to play. 73 Alan W1HYV ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[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.

Re: [Elecraft] Help with troubleshooting K2 receiver?
Glenn, Whoa!!! One thing at a time and first things first. First, the VFO voltages. The slug on L30 should normally tune near the top - about 2 to 3 turns from the top is normal. If that is not true, first check the number of turns on T5 - count only the turns that pass through the center of the core. If the turns on T5 are correct and spread about the same as the illustration in the manual, then verify that all the capacitors in VFO Range Selection area (see the RF Board schematic sheet 1 of 4) have correct values and are well soldered. Once you have the VFO voltage ranges within bounds with L30 in a normal position, then we can work on the other conditions that you have mentioned. 73, Don W3FPR Glenn Maclean wrote: I have my K2 built to the second alignment step.

[Elecraft] ECN 1 Apr
20M: Heard N0SS at the start of the net but Tom faded in mid-transmission. W3MC was 10 over 9, and did the QNP. Heard no one else. 40M: Kevin at about audibility but not really readable due to QSB. Tom was 579 when I checked in and 15 over when I headed for the shower, probably what would be expected as the sun had just set here. All others very weak. A few readable with difficulty. N0BK at about the same RST as Tom @ 0227. I'd say I can't wait for a spotty sun, except I'm enough of a realist to know I will wait, like it or not. 73, Fred K6DGW - Northern California Contest Club - CU in the 2007 CQP Oct 6-7 - www.cqp.org ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Silly KPA100 Question
Respecting the placement of the solder lug on the antenna connector J2, is the lug really supposed to be installed on the screw nearest the top edge of the rear panel? Seems if its installed there it's going to come close to interfering with the with the circuit board to which the rear panel attaches (it can be made to work, but it will be a tight squeeze). Figure 22 shows the rear panel inverted; should the installation instruction be interpreted installed on the screw nearest the top edge of the (inverted) rear panel (which is, nearest the bottom edge of the panel)?

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?
