In fact, when scientists want to study lightning, don't they do it by attaching earthed wires to fireworks and shooting them into thunderclouds? You might be right, but I'd like to understand why - it sounds like you'd be making an almost ideal lightning target :-) I think it's already a target, being a conductor in the sky and all, and nothing short of taking it down will change that (the lightning would much rather go through metal for some distance rather than air). The question is, is it a target that is open at the bottom, very near your rig, with lightning shooting out of it across your desk, looking for a place to go? Or is it a target that is grounded at the bottom, giving the lightning someplace to go that isn't your rig? That's how I think of it, but having said all that, I'm in a nice low area that never ever gets struck, so I don't worry about it. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Phone cords are the same way, on purpose (not because they are cheap or trying to cut corners), and the tradeoff for being almost unworkable in a splicing situation is that they last far far longer than a heavier gauge, more traditional wire would. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Even then, 'recalibration' will catch any tuned circuits drifting, but isn't really a test to see if there's performance degradation from other reasons. I have a habit of recalibrating or doing other repairs only when I see something wrong. I see something wrong when some critical values change. I log the key data about a new rig so I can look back from time to time if I'm suspicious that something's amiss or if I'm simply bored and want to tinker -- What Ron says sums up the situation very well, why would you want to recalibrate the radio unless the performance is falling off. To quote the often used phrase if it ain't broke, don't fix it. Not many hams would do this to the latest Japanese/USA black box, so why do this to a K2? The radio is tested to a degree every time it is switched on and used on the bands. A fall off in TX power output or RX sensitivity soon becomes apparent. Is important however, to record *all* the tests you make on original commissioning, calibration and after any mods that may be done for future troubleshooting if required. By and large unlike earlier tube equipment, solid state equipment performance does not change all that much unless a fault develops and one is usually made aware of this pretty quickly by other hams if not apparent to yourself. Apart from odd quirks that can occur with some radios, I would be rather more worried if the performance does drift as that would not say much about the quality of the original design or the components used. With commercial communication systems these are tested with specific routine maintenance programs on a regular basis to ensure that any defect is picked up before it becomes a problem. The reasoning behind this is to prevent unforeseen outages as these can mean lost revenue for the company or a possible threat to safety. Ham radio does not normally fall into this category, so unless tinkering with the K2 calibration really turns you on, it is far better to use the radio for the purpose it was designed for in the first place, communicating with other hams.

However, when manual asks (page 47) to adjust R1 for a reading of 3.80V volts it seems peculiar not to have enough adjustment scale to achieve or exceed the required voltage. that was exactly why I was somewhat concerned. I was ALMOST there, but not quite. It was disconcerting to me that to get almost there, I had to fully crank the pot to its end stop. When a manual tells me to adjust to a voltage, I like to be somewhere in the middle with my pot...otherwise it makes me wonder what I did wrong. I am still wondering :) As for the alleged 5-10% tolerance of DMMs that one poster suggested, I'm skeptical. If they are that bad, then why doesn't the manual say to adjust to 3.8 volts since the hundredths digit must be totally meaningless. In fact, I see that Fluke claims a .3% DC voltage accuracy of their basic 73/77 multimeters, so thinking the problem lies with my meter doesn't really cut it for me.

What a great feeling to power up the K2 to check out the control and display boards, and to hear the relays click and see the menus working. So far the only thing that hasn't quite reached recommended values is that my control board AGC voltage maxes out at 7.92 V rather than the 8 V mentioned in the manual. I'll have to search see if anyone has reported a similar thing. I'm really glad you posted that because I just ran mine through those tests a few days ago and was slightly troubled to note that mine also maxed out just under the 8v. I think mine got up to 7.98. I'll be interested to see what you find out, or who else might chime in with some data.

Re: [Elecraft] K2 construction options, now or later?

My question: may I build the basic K2 and add options later when my bank account lets me do it, like the 100 watts options or noise blanker, internal antenna tuner, etc? Yes. In fact, the manual strongly advises (almost orders) you to build the bare K2 first and add the options after it is all verified running. Makes sense for troubleshooting as well as for pocketbook! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Unless I am misunderstanding what you mean, I think you went the wrong way with the dollars...$4000 in 1978 is about $12,000 today. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Wow, 23A...just how QRO are you going to go? Is this for use with the K2/100? Isn't that a lot of amps?

On the Elecraft website, (from as far as I can see)...when a user tries to do a dummy run...I think that you may end upactually placing an order...and I dont want to do that just yet... I'm not seeing that. I went to the order page, checked a few items, clicked add to cart. The system then asked my zip code and shipping method. The next screen had my shopping cart with the items and the shipping and the grand total which seems to be what you are looking for unless I am misunderstanding. Only upon clicking Check out now is the next step reached, which still requires several more screens of selecting payment type and entering the credit card, etc etc. As a note to the Elecraft folks, it's a very nice cart system.
