[Elecraft] K2 MOJO Back in the Box
Hi All, Thanks for the suggestions re recovering from a loss of receive audio. I took all the modules out, put them back and the K2 mojo came back. I'm still baffled about what occurred, but hey I'm not complaining. I finally got around to building the KAT100 over the past week - wow isn't it like magic when you are building an Elecraft kit and the various parts suddenly come together and you can see the end result. For the KAT100 for me this occurred when I bolted the RF board to the front panel.

[Elecraft] Installation of Q7 and Q8 HELP!!!!
I followed the PA transistor Q7 and Q8 installation instructions to the letter and there is NO way I can secure the heat sink cover. Yes, the nylon shoulder washer is flush with the hole on the transistors and I made sure it is centered, I even measured the screw to make sure I'm using a 1/2. I did a search to see if anyone else had a problem with this step but I couldn't find anything that would give me a hint as to what I'm doing wrong. I REALLY want to know how the heck this is going to work when all this stuff is on the back side and it is higher than the standoff spacers. PLEASE help me with ANY suggestions 72/73 Ann ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

You seem to imply that a 1/2 screw isn't long enough? The screw goes through the PC Board (~1/16), a fiber washer (1/16), a 1/8 standoff, a shoulder washer (1/16), the transistor tab (1/16), insulator and heatsink (~1/16); total ~3/8, leaving plenty of thread. A 2D fastener is about 1/4, which should be very close to the fiber washer (1/16), a 1/8 standoff, shoulder washer (1/16), the transistor tab (1/16), and insulator. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Are you sure the shoulder washers are upside right? The shoulders hold the tab and the turned-down part goes through the tabs.

[Elecraft] MD-2 Micrphone
I took advantage of the reduced prices and ordered the MD-2 and CB-1 microphone and base for my K2. They arrived and certainly look and feel very nice, but no surprises there. I have a couple of questions, anyone can be of help with them, I appreciate hearing from you: 1)I also have the Elecraft/Heil hand mic and was able to install the 5.6k resistor into the mic plug, rather than into the K2. This worked out fine and now I can use other mics and data sources (I use a RigBlaster for psk31)with the K2. Has anyone tried to put the 5.6k resistor into the plug of the MD-2 and is their anything special I should know? 2) I seem to have an 'extra' part that came with the order. It is a piece of metal about 3/4 inch long, threaded with standard screwdrivers slots at each end. It's not immediately obvious to me were this goes. (And I forget if it came with the microphone or the base.) 3) I really like the idea the there is a the jack for a footswitch. Does anyone have a source where I can pick up a switch? 4) Also, along the same lines as the footswitch, is there an 'always on' position on the PTT switch on the mic ?(I haven't actually used the mic yet because I haven't yet installed the resistor).

[Elecraft] BFO test frequency out of range
Hi everyone! I have been building SN 4078, and all has gone smoothly so far. The radio is finished and works (except for the problem below) as do the SSB and DSP options. I have been chasing one problem for a while however. When I did the BFO test the BFO Low Freq came in as 4911.23 which is ok. The high freq was only 4915.77, a bit short from the 4916.3 it is supposed to be. I have replaced C173 and C174 with diffrent caps (same value), confermed L33 is working properly and isn't shorted to anything. I even removed it from its spot (kept it hooked up) and it didn't make a sizeable change. The voltages at U11 pin six was 5.89 and pin seven was 5.3 which are within tolerance. The DC voltages everywhere else seem reasonable. The AC voltages anywhere I could measure seemed reasonable. One intresting thing to note is the BFO chrystals seem to be the wrong frequency. They are labled ECS V 4.9136-S Korea G3. This is diffrent then what the instruction manual states they should be labled. The remaining chrystals on the board, except the VFO, are ECS V 4.9136 -S Korea J3. A little diffrent labling but same frequency. I have confirmed the rest of the chrystals on the board are correct. I could be totally off track with the chrystal idea... Can anyone confirm it or give me ideas as to what I might have done wrong? I love this radio, but when I transmit on the upper sideband it doesn't suppress the carrier at all (lower sideband is fine). I believe this problem is the result of the problem above since I couldn't set the USB filters correctly.

[Elecraft] Leads to 2SC1969
OKI'm really in a pickle now. After my third attempt to re- install the 2PA transistors Q7 and Q8 so that I can put the heat sink on I managed to stress the leads so much that they are either broken off after the bend or they are near to the point of breaking. Would it be ok if I just solder a wire lead to the hole through point then solder a lead to the remaining leg on the 2SC 1969's??? Thanks any advice would be appreciated. 72/73 Ann ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Is it possible to monitor digital transmissions.
Hi Jerry, I can't imagine running PSK without PSKmeter (http://www.ssiserver.com/info/pskmeter/). After reading about it in QST last February, I ordered and built the kit. PSKmeter is a essential one-trick-pony for PSK ops. Very neat. I have built and use 2 of them. There is also another product out there IMD Meter out there, but I have never seen or used one.

RE: [Elecraft] Is it possible to monitor digital transmissions.
I have a cable built up for a K2 to run digital wired for manual transmit without the vox on, or with. Interfaces to the sound card inputs. I will be happy to send it to you free. All you need after that is one of the software programs to run the PSK, RTTY and so forth. If you cannot hear the computer or the receive, then just use a splitter for the input to the computer.

[Elecraft] KPA100 voltages
I am building a KPA100 and page 41 shows res to gnd at J3 red, Q1 Q2 collectors as 10,000 ohms Mine is 128 ohms and Gary says his is only 350 . OK The voltage chart says to check at 14v DC in and 10 watt setting or less. I get Q6 D=72v but if I turn up the power control the voltage goes to .6 where it should be. Q8 is similar on the coll I get 56 v but turning up the power brings it down to 6v (s.b. 11) There is no output from this unit and one thing to check is T4. Am I reading this wrong . I wound T4 according to page 27 where one wire is designated 1,2 the other 3,4 but the schematich shows one as 1,3 the other as 2,4 The other voltage differenmce that I have is on U7 where pin 3 is 3.6v(s.b.14) and pins 56 are 0 (s.b. .68) Mayabe I have a bad IC Any comments or suggestions.

Spent most of the weekend building K2 #4595. Performed the PLL reference oscillator range test. The result was 8.0 khz., 1.8 khz. lower than the acceptable minimum of 9.8 khz.

[Elecraft] Elecraft CW Net Report for December 19th, 2004
Hello All, This evening was not very good for my reception. Without Tom's help I would only have three folks on this list. I heard a few of the others but I do not know if we could have exchanged much more than call signs. The QSB was quite deep on 20 meters but the noise was the biggest problem on 40 meters. I only heard Tom and Peter on 40 so the relays were important. Tom was in a cold shack so I shooed him back into where it is warm and have not received the information from him yet. Tomorrow I may just have to post another list with the ?? areas filled in. I need to get that 80 meter antenna up so we can try that band soon. On 14050 kHz: KO6WL - Howard - CA - K2 - ??
