[Elecraft] How Do I Recover From A Hard Reset?

I am helping a local ham who accidentally did a hard reset on his K2/100. He has given me his original manuals which have the various initial calibration settings recorded, but as he did the hard reset accidentally, he did not write down the settings you are supposed to keep before you do a hard

[Elecraft] K2 Frequency Display Problem

Help! Yesterday, the frequency display on my K2 #5113 stopped functioning properly. When I turned off the K2 I was on 14185.09. When I turned the K2 back on later in the day, it read 14063. Now, every time I turn the radio on, I see 14063 on 20M no matter what frequency I was on when I turned

[Elecraft] Re: Tokyo Hy-Power Amps?

I can't comment on the Tokyo Hy-Power amps, but if you are interested in building your own 100 watt amp, K5OOR has a new group build project underway for a 5 watts in, 100 watts out amplifier based on a December '05 QST article called the SuperPacker Pro. Here is the url. to his web site for

[Elecraft] Mic Configuration Question Part II

Thanks to everyone for the suggestions. I have confirmed that the mic is wired as per the MH2, including the resistor between pins 16. I have done all of the KSB2 alignments as far I can. I still get a 10 watt carrier when I push the PTT in LSB and USB. In CW when I push the PTT, I am getting

[Elecraft] Heil Handi Mic Configuration Question

I am finishing up K2 #5113 and have run into a snag configuring the microphone on the K2SB2. I am using a Heil Handi Mic HM-IC. Bob Heil told me to get this mic as he said it would optimize my 706 MKIIG and the K2. I'm using the Kenwood 8 pin cable for the K2, again per Heil's recommendation.

[Elecraft] Low RF Output on 20 and 30

I have just finished my second K2, #5113. I am getting only 0.30 watts output on 20 and 30. Adjustment of L8 and L9 and C21 and C23 has no affect. All other bands work fine and give me the RF output called for. Any suggestions on where to look? Jonathan Gottlieb WA3WDK

[Elecraft] Part 1 Test Failure

I am currently building my second K2, #5113 (first is #4853). I have run into a problem with the Alignment and Test, Part 1. When I first turned the K2 on, I got INFO 201, but it did not switch to the default frequency display for 40 Meters. I turned it off and turned it back on again, now all

[Elecraft] KAT100 Won't Tune When IC706 Also Turned On

Any thoughts on this one: Today I hooked up an antenna switch so I could run the K2/100 and the ICOM 706 and switch between them and use one or the other when I want to. Both radios run off the same Astron SS-25 power supply. When I have the 706 turned on and RX only, the KAT100 will not

[Elecraft] K2/100 Portable Battery Pak Question

Does anybody have any experience using the HFProjects Power-Pak with a K2/100? It is a nice 12v 7ah gel cell with built in trickle charger (www.hfprojects.com). I wouldn't expect it to power the K2/100 at full 100 Watts, but I'm thinking it would be a good way to have a nice power supply for

[Elecraft] K2 Speaker Problem

I had the same problem. Go into the box and bend the speaker/headphone jack down. It seems that when you put in the headphones, it bends the connector up so that when you pull it out, it doesn't make contact to engage the speaker. Good luck. Let me know if that fixes it. Jonathan

[Elecraft] Looking for some more Punch on SSB and No Hi Cur on 30 M

I've got k2/100 #4856. I've done the C80, C81 mod. Everything checks out great, except I still get Hi Cur on 30 M and it doesn't seem very robust on 20 or 17 SSB. 80 and 40 M SSB output is fantastic, often peaking right at 100 watts. I get 100 W in CW key down on all bands except for 30 M

[Elecraft] KPA100 Hi Current on 30M

Almost finished with my KPA100. Power output is 100 watts on all bands except 30M where I get hi current display over 55 watts. Any suggestions? Jonathan Gottlieb WA3WDK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a

[Elecraft] KPA 100 Power Calibration SWR Question

I have just completed the Power Calibration (R26 andf R27) on my KPA100. The SWR shows 1.0-1 on 40 and 80M, but then goes up from there. It is 1.5-1 on 10m and power output as indicated on my external power meter shows power declining as the SWR is increasing. I am using an MJF 264 dummy

[Elecraft] KDSP2 U2 Solder the leads?

Page 8 of the KDSP2 instructions are very clear about soldering the tab of U2 in order to relieve mechanical stress from the leads of U2 when the KDSP2 PCB is mounted and the mounting screw tightened. The instructions do not, however, tell you to solder the leads. This may be obvious to most,

[Elecraft] VCO Oscillator Problems and T5

I recently posted a note regarding the fact that I was stuck on the VCO Oscillator Test (p.60) of my K2, #4856. Don, W3FPR gave me some good suggestions, but nothing seemed to fix the fact that I couldn't get the oscillator to oscillate. I replaced Q1 and Q2 and the JFET. Still no

[Elecraft] VCO Oscillator Test Problem V.2

I checked carefully for shorts and don't see any. Put everything back together again and VCO reading is still .00, but Q1 does not seem to be warming up anymore. Have I fried something? It has been suggested I trace 8R and 8T, any advice on how to proceed on that? Thanks. Jonathan

[Elecraft] VCO Oscillator Test Problem

I am building K2 4856. I've run into a real problem. All tests have gone great until the VCO Oscillator. In doing the VCO Oscillator Test I get a reading of 0 AND Q1, Q2, Q3 and Q4 on the Control Board all got very hot. Hot to the touch. Not sure where to go with this one. Any
