Re: [Elecraft] Scratches
Gang, The stuff you are referring to is used a lot by RVers to keep stuff from moving about. One caution, if you leave it in contact with painted items for a long time, it will leave marks that may be difficult to remove. If we are talking about the same stuff, it is much cheaper at the various Dollar discount stores.

It fits nicely on top of the K2 but I was wary of scratching the finish. So I applied to the bottom of the speaker, several of those round felt pads that are meant for the bottom of furniture legs. No more worries about scratching the K2! 73 de Larry W2LJ Howdy Larry: A while back I bought a roll of stuff used to line your kitchen drawers and shelvesit is called Contact and looks like a cloth embroidery but is made of some kind of material that is absolutely non-skid.

It is great stuff and doesn't cost muchyou can easily cut it with scissors to size.

One could also fool with idea of the points being: (distance * (PowerOtherStation + PowerMyStation) / 2) Hmmm Good idea. But I'm thinking distance propogated by the signal, not earth-surface distance. And you'd want to adjust for the effects of gravity as the signal passes nearer the surface of the earth. To keep it fair, I think we absolutely have to adjust for the attenuation of the signal due to the directionality of the antenna. I should get more points for a QRP QSO off the end of my dipole than you guys with beams get for QSOs where you're aiming right at the station. Ditto for the receiving antenna. I'll get started on the math unless one of you knows this off the top of your head. We'll want to nail this down pretty quick so the logging programs will have time to implement and test it.

[Elecraft] K2 Microphones
Gang, Just put the SSB board in my K2 [S/N 4858]. I have tried my Shure 444 with the K2 and seem to have no drive. I think I will try a portable telephone headset. I will need to get some bias for the mike from the K2 then I'll find out if I have a problem with the SSB board or my old trusty 444. Would like to hear from those who have used cheap/nonstandard microphones with the K2.

[Elecraft] K2 As Only Rig in Shack
Gang, My basic K2 [5 watt version] is my station rig. I have a NC-20 in white metal for field use. That will be supplemented by a K1 as soon as the budget will stand it and SHMBO [lets not start that again] approves. As for general coverage, I have a Hallicrafters S-38 [circa 1946] that provides all the band coverage one could want at least on HF.

[Elecraft] K2 Low Output Power
OK, I confess that after building control and receiver circuits [carefully] with no problems, I wanted to believe the rig was 100% after initial transmitter alignment. I put the rig on the air and made contact immediately. THEN: a friend loaned me his OHR WM-1 wattmeter so I could actually measure the output. It was all over the map, but always low and not very repeatable. I checked the soldering. I resoldered everything that looked even a little suspect. I measured the resistance of each of the toroids and transformers. I measured dc voltages. I monotored the ALC circuit. I measured rf voltages in the transmitter with the provided probe kit. Everything seemed ok except the transmitter was low on drive and the power supply current was high. Wait, I see a patern! Time to check my dummy load. [I have been using 2w dummy loads for my other qrp rigs. For this job the only thing I have 2w is a Heath Cantenna 2Kw] The Cantenna is open! Dummy load is 100Kohm. Not good - but happy dance, the radio is fine [I was very careful with the finals! Very short test times and reasonable current limits. I check the radio with my qrpp dummy load [1 watt] and all bands put out the asked for [low] power. I repaired the Cantenna and touched up the transmitter alignment. Power is predictable and controlled on all bands. Time to open the SSB kit. The lesson once again is do not assume things - I had not used the dummy load since going qrp 10 years ago.

[Elecraft] K2 VCO Alignment
S/N 04858 is thru the 40m receiver test [Alignment and Test, Part II]. The only problem [after replacing 10 uH L31 with 12 uH to get sufficient range of 4 MHz Osc. Cal.] was when I performed the VCO Voltage Readings. The voltage readings were well in range, but two bands [20 17 m] had frequency readings that were way out of band [20=8,757 and 17=24,254] so, after searching this wonderful archives, I performed direct frequency entry and everything fell right into place -and- after that, no more funny readings. Well, except: BFO Low Freq. measured 4912.76 [should not read more than 4912.7] however, I have not yet calibrated the 4 MHz Osc. as my counter needs work. Continued right through to end of Part II and copied a QSO - FB! Now I am ready for the last big build cycle! I assume there will be no reprecussions from the initial funny readings. I have been having so much fun building the K2. Wayne K9NE K2 S/N 04858 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 power meter/wattmeter question
Guys, If you read the specifications carefully and do the math, at 10% of scale the reading can be off by a huge percentage even with a fine instrument like a Byrd.

[Elecraft] Potential Elecraft Kit
Gang, One of the insturments I always wanted for home use was a spectrum analyzer. Nice to have sound card analyzers with software and all, but a real rf analyzer in a small, functional package would be so great. With some careful trade off decisions it might even be affordable! The display is a big headache if you don't have a good Oscope handy but a creative designer [or two] might be able to do the job. I suppose it would not have the broad appeal of a K1, 2 or even a very compact antenna tuner, but it might appeal to a few hundred hams and others who do bench work.

[Elecraft] K2 Display
I am building K2 04858 and have arrived at the display installation in the front panel. I have a couple questions and am too impatient to wait for the Elecraft gang to open up about noon [here] Monday so I turn to this group. 1. When does the kind of flimsy white tape/paper come off the diffuser/LED backlight assembly? 2. Is only the front tape removed? 3. The LCD display has a grey mylar looking tape on the back. No 'stripes' but opaque so I assume it must be removed for the backlight to shine thru? 4. Does a correctly prepared LCD display have anything on the back or should I see bare glass? 5. Any problems identifying the removable film from the front of the LCD display [DO NOT PICK OFF THE THICK PLASTIC MATERIAL .] I assume this is the clear case of the LCD? Curious minds. Obviously my first K2. Some of you have tons more experience. Build going well so far. Only a couple anxious moments installing the push button switches, bent a pin and managed to get one switch cocked but fixed that.
