Re: [Elecraft] Droid
I owned 2 for about a week. Super WOW factor. And, during that time I downloaded a ton of free apps which were really neat and a lot of fun. But in the end, I confirmed that the battery life sucks. I mean - really sucks. A couple of hours just goofing off with the thing ran the battery down, and yes, I did condition it like the book said to, so the capacity just isn't what it should be. In the end the real reason I took them back was that the phone just wasn't as easy to use as a phone should be. Too much other stuff and not enough phone. HOWEVER, if someone had sent this message to me before I got them, I would just disregard it. SO.

Re: [Elecraft] I need some grounding-strap guidance, if'n you please
Well, I guess I need some advice here as well. I had not considered the problem of different grounds. I am building a house, now, where the electrical wiring will come in at one end of the house while my radio room is 70 feet away, at the other end. I had planned on a separate grounding system at the radio room. Would it be best to connect the two grounds? If so, how would be the best way to do that? Or, should I have the electrical wiring come in at the same end of the house as the radio room, thus eliminating two separate grounds?

Even a bad ground provides plenty of lethal current at mains voltage. When I have a shop setup in a basement, garage or anywhere with a floor like that I make sure the outlets are GFI protected. It's cheap insurance. Over the past 30 years we've moved back to the electrical equipment designs of the 1940's and 50's in which safety is accomplished through insulation rather than through a grounded enclosure. The fact that few modern tools or appliances have 3 wire plugs testifies to this approach. Such equipment is (apparently) very safe. (Safer than many of the old AC/DC radios, etc., of the 40's and 50's - especially after us young Hams unknowingly compromised the insulation by taking a knob off exposing a bare control shaft or leaving insulators out from under the chassis). But the reliance on insulation rather than grounding for safety seems to be bringing us back many unsafely grounded outlets. It's now very common to have even brand new construction, signed off by all the appropriate inspectors, turn up reversed wired outlets and missing grounds.

Re: [Elecraft] OT: CQ WWII naval radio ops
When I first joined the navy in 1961 it was as a radioman (I got a meritorious promotion out of boot camp because of my amateur license). We copied code on old CAP only manual (superfluous) typewriters we called mills. Anything much beyond 20 was a challenge to get right, and the 5 character groups were what we copied. There was nothing intuitive about them that we routinely use to copy in our heads. And, since they were encoded, they had to be letter perfect. I think 35 - 40 wpm of 5 letter groups, hand typed, is doable, and I suspect a lot of operators could do that, but it would wear most radiomen out pretty quickly.

Dan, The original question has already 'morphed' to one of general use of air or products for cleaning circuit boards. Let us think about one of the reasons for that statement in the manual. The VFO A encoder has a plastic plate under it. We all know that plastic can often build a static charge which will attract dust and other small particles. If the area under where the plastic will be mounted has lint or dust, it can show up badly when the plastic is attached.. That could include gently wiping the area with a slightly dampened lint-free soft cloth, or even using a cloth one would normally use to clean eyeglasses. The use of a dry brush may not work if used on the plastic because some type brushes may actually increase the static charge and make matters worse (but then, the manual states to clean the area *under* where the plastic will mount and does not refer to the plastic itself). Use whatever works and is sufficiently kind so that no damage occurs. A quick 'breath of air' from your mouth may be all that is required. 73, Don W3FPR Dan Nixon wrote: I'm an old ham who has built a lot of kits over the years.

RE: [Elecraft] K2 Mods
Hi DW, When I installed Don's Fixed Audio Output board I didn't want to drill any holes in my K2 either. Instead, I routed the output to one of the two existing holes on the back panel which I terminated in a RCA phono jack. The other hole got a miniature (not pc board miniature, the old fashion type with a shaft) 10K pot which I wired into the FAO board in place of the pc board pot. Everything fits just fine, and with a small knob on the pot shaft, I can just reach around and increase or decrease the output. When properly adjusted on 80 and 40, output on 15 - 10 m was too low for my taste. 73, Tom -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of DW Holtman Sent: Sunday, August 17, 2008 6:41 PM To: Elecraft@mailman.qth.net Subject: [Elecraft] K2 Mods Hello, I finally got around to installing the CW LED tuning indicator by Tom Hammond N0SS. It works great, I should have put it in way back when, upon completion of the K2. It is both sensitive to weak signals and selective. Next I'm thinking about putting the Fixed Audio Output for digital modes created by Don Wilhelm W3FPR. It looks very well designed. Don has put a lot of time and effort into this project to design, build and document so everyone can read and understand it. Have many put this in and are you happy with the results? I'm a little nervous about drilling holes in the back panel. Don also has a another project on his very informative web page. This is a switch box to make the connections from Digital modes to SSB without unplugging cables and changing the compression settings on the SSB Board. Has anyone built this and how do you like it? Would it be possible to combine the two. So a fixed audio would be applied to the mic plug to use in the switch box? This would also eleminate drilling the back panel? I did not know if I should send this to Don, since he is the expert on most things related to the K2. But, I thought I would send it to the group for any ideas and hopefully Don will let everyone know what he thinks.

RE: [Elecraft] Computer Control of K2
Hi, To all who replied, thank you for taking the time to assist me. Don, as you suggested - and as Occam's Razor once again proved - it was as simple as cabling. I had the connections to the K2 and the KAT100 reversed. All is now well in HRD land. 73, Tom -Original Message- From: Don Wilhelm [mailto:[EMAIL PROTECTED] Sent: Monday, July 21, 2008 11:41 PM To: [EMAIL PROTECTED] Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] Computer Control of K2 Tom, Since the control for the K2/KPA100/KAT100 linkage uses internal K2 signal lines that are completely separate from the TXD and RXD signals between the computer and the K2, the fact that your K2/KPA100/KAT100 still operate is not any indication of 'goodness' regarding the link to HRD. Check the port settings on the computer, Check the K2 menu to be certain PORT is set ON. Be certain the cable from the computer goes first to the K2 (or the KPA100 if and only if it is mounted on the K2 top cover). If the cable to the computer goes first to the external KAT100 (or an externally mounted KPA100), the computer connection will not work because there are no wires in the KAT100 to K2 cable to carry the TXD and RXD signals. 73, Don W3FPR NG3V wrote: Good Evening Group, Here's an odd one.

RE: [Elecraft] Burn in of KPA100
To Don, Ron, et.al., Thanks for the information about tightening the screws. I just finished the process - not 5 minutes start to finish.

RE: [Elecraft] K2: A small milestone!
Congratulations Mike, That is a most worthy achievement. Having been through several cycles since 1958 (Yikes, that seems like a long time) I gotta say I am never sorry to see the troughts come. Peaks are just overwhelming, sometimes. I once worked WAC on 10 meters in 15 minutes with about 20 watts but at peak times that ain't a big deal and the band was like a cocktail party - too intense. I like the quieter times best. 72, Tom -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike K8CN Sent: Thursday, May 22, 2008 9:07 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K2: A small milestone!

Re: [Elecraft] Auto-Spot Feature and Hearing
Hello group, I doubt if I invented this, but here is a fool-proof method of zero beating: I start Spectroscope which has been set to display a frequency mark at 540 Hz (my preference). I then drag it over to the right side of the screen, leaving room for HRD on the left. As I tune, I simply bring the peak of the desired CW signal under the 540 mark and I am dead bang on. Of course I must also set the sidetone on my K2 to 540. BTW, I found a free program for my PDA that registers the frequency of a tone. Find a steady tone, somewhere (birdies are ok) and tune it untill it is loudest - that's your ear's sweet spot. Measure the frequence, set the K2, set spectroscope, and away you go. 72/73 Tom, ng3v (on cw since 1958 and enjoying it more every year) -- Original message -- From: Lee Buller [EMAIL PROTECTED] The Auto-Spot feature is very cool and has been excellent for me. I have not yet loaded the new release, but I want to comment on what my experience has been. My hearing has diminished from 300 Hz all the way to 15,000 Hz and beyond. IN fact, I peak at around 2,000 Hz and roll off some 60 db at 4,500 Hz. The low end of the spectrum suffers as well as I roll of around 800 Hz some 20 db. I have very little high end unless I crank it up and the walls start vibrating. Hearing Aids would correct all this, but at $3,000 pluswell, you get the picture. So, I always spot CW signals wrong because of my hearing defects. I have a tendency to be high and the station does not hear me. I have to remember to tune lower and to a softer sound of 600 Hz or so. This has proven to be a problem during CW contesting and I have to really work at compensating for my hearing loss below a thousand Hz. The Auto-Spot feature changed all that. Just very cool. I want to see how it works in a contest. So, protect your hearing and do not get old. Use hearing protection while mowing the lawn, going to rock concerts (what a fun time that was), listening to your Iron Butterfly LP (HE HE HE); use reasonable volume when working the contests, and while working in noisy environments (25 years in broadcasting using headphones). 73 Lee - K0WA In our day and age it seems that Common Sense is in short supply.
