[K1-2277} Front Panel construction--push-button switch installation
Locked
 
|
Hello all. First time build of a K1 and I could use some advice on
installing the switches. The pins I have sit a bit narrower than the pin holes on the circuit board. Slight pressure separates them sufficiently to fit the holes, but they do not want to extend through the holes, they extend just far enough to fill the hole but not quite far enough to break through the plane of the board on the side opposite the switch. "Switch pins are fragile" keeps me from applying too much force worrying about bending the pins, and I did manage to create a 90 degree bend in one. Am I missing a trick?

Rich,
The pins are not all that fragile - once they are started into the holes properly, you can apply a bit of pressure (just don't 'beef them down'). The pins do not extend much beyond the board surface, and in some cases will be about flush. Be certain you heat the switch pin when soldering and not just the solder pad - if you have any doubts about a goo connection, you can solder them from the top (being careful to keep the iron away from plastic parts). 73, Don w3FPR Richard Hill wrote: > Hello all.

Much has been written on this reflector about the sound of the sidetone,
particularly the K2's sidetone, and about stability and narrow band clickless keying, stable signals, with today's operators asking for razor-sharp selectivity in order to copy signals in a crowded band. Here are some recordings of actual COMMERCIAL CW maritime signals on the 600 meter (500 KHz) band from the 1970's in European waters http://www.n1ea.coastalradio.org.uk/W1DM_500_EU_74.zip How many stations can you copy at once? And how about that keying by real fists on mechanical keys! As for the stability and clicks, some sound like bullfrogs with a belching problem, others redefine "yoop" and still others sound a cat having its tail pulled. I rather like the one that sounds like a canary with laryngitis; My one-tube 6V6 rig sounded much like that. At about that time our Ham bands didn't sound much different! And, no, most of them didn't have lousy power supplies with too much ripple: many ops ran MCW. All maritime consoles were capable of modulating the carrier with a tone if desired. It was required when sending distress signals. If those sounds don't grate on your ears, try some real spark transmissions in the next link below. These were probably recreations produced by the antique wireless assn using real spark transmitters (in suitably shielded rooms). No wonder us O.T.s think the K2's sidetone sounds sweet and smooth! http://www.n1ea.coastalradio.org.uk/NBD%20spoof.zip And there's more to hear at: http://www.n1ea.coastalradio.org.uk/ Ron AC7AC _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

The calls were different when I was a 16yr old in coastal marine [West coast of NA], but that *is* what 600m sounded like on the nighttime shifts. I'm so used to our current near-perfect spacing from keyers and computer-sent CW, I have to really concentrate to copy from that what I used to so easily. OK...I was younger then. A lot of fists-afloat were pretty bad. Mine on-shore was perfect, of course. I don't remember spark thank God, I'd be much older now if I did and likely dead. 73, Fred K6DGW - Northern California Contest Club - CU in the 2007 CQP Oct 6-7 - www.cqp.org _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

So why did they all sound so different? Was is operator preference or
equipment limitations that determined the tone? Mike AI4NS (Just a young pup.

For one thing, a marine radio's first priority is reliability. Lives may depend on whether or not the radio works - not just the lives of those on that particular ship, either. And unlike aircraft or landbased radio, repairs are limited to what you have on the ship. So the radio gear is way overbuilt by landlubber standards, and signal quality isn't the first concern. Another factor is that while the radio is a vital piece of equipment, ship owners aren't eager to replace and upgrade them too often. Part of the reason is the cost of new radio gear itself, but a bigger cost is that the ship isn't making money sitting tied to the dock getting a new radio set installed, checked out and approved. So they tended to use the same old radio sets as long as possible, meaning that rigs of many different vintages were on the air at the same time. Still another factor is that for many sets the signal quality was influenced by how the rig was tuned up. If you've got a ton of traffic to pass and the weather is getting bad, you may not spend a lot of time tuning the rig for an absolutely perfect T9X signal when T8C will get the message through just as well. That's just what I've been told by the old salts who actually did it. 73 de Jim, N2EY ************************************** See what's free at http://www.aol.com. _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Being a teen and very poor, my bug was a J-36 I'd found at Sam's Surplus Sales on Pico St in downtown Los Angeles. It was sort of proletarian-looking [OK, very proletarian], not shiny like those of my crew mates, but it could produce civilized dot speeds without added and ugly weights. The recording at Ron's first link, except for call signs, sounds like what I heard on 600m in the mid-20th century. Thanks for coming back to the hobby.

These guys have it right, from what I saw. In the US maritime service the
FCC kept increasing the rules for stability, signal purity, keying, etc., but the rules applied to when the equipment was manufactured, so an old console that drifted and yooped was legal as long as it was still in service. Ship owners never changed out something that worked, so as long as the radio console was repairable (and there wasn't anything that couldn't be fixed) they kept the same old console. On an old vessel in the early 1990's I found an ancient black RCA console. If you've not seen a shipboard radio console, there are pictures of one aboard a restored WWII cargo ship here: http://www.arrl.org/news/features/1999/0216/2/?nc=1 The vessel I was called to work on had been taken out of the "mothball fleet" to haul supplies to the Persian Gulf during Gulf War I and my eye was drawn to a little panel on the console marked "Crystal Detector" with space for a galena crystal and cat's whisker! You see, all radio consoles had both a main and a backup receiver as well as main and backup transmitters. At one time that crystal set was the "backup receiver". The crystal was long gone. The console had been "upgraded" to a regenerative receiver for use in case the main superhetrodyne receiver broke down in an emergency, but the panel to mount the crystal was still there. That's why MCW was required for all emergency communications: crystal sets don't have BFO's <G>.

I am generally a lurker here but I HAD to tell you, Ron D'Eau Claire, how
much I enjoyed these links. I was called a "LID" in 1975 for less, and here 30 years later I feel better as I now have a defense. WOW what an eye (ear) opener! It brought back a vivid memory of my Uncle Jesse, who was a radio operator for the US Navy on an ocean going tugboat (forgot the name). It was 1967 or 1968 and we met him on his boat at San Pedro, California. He was just about to get off work but was copying 5 letter code groups to paper. He was writing these 5 letter codes with one hand and flipping the pages of a newly purchased Playboy magazine with the other, commenting at the pictures at the same time. I asked about it later and he said it became automatic after a while. He also said that the message was possibly classified but he never knew whether it was or not. Someone else decoded it. Again Ron, Thank you, this is great fun and infinitely enjoyable. I'm even going to bookmark that site.

Thanks Ron,
Takes me back a LONG time ... Was R/O on several USC&GS/NOAA ships and "hung out" at WPD in Tampa. Lots of 400 - 500 kHz time. Tx was a TBL with M/G set in the "basement".

Hello all,
I had a question about using a digital multimeter for AC millivolt measures. I have a radio shack 24-range DMM and when I set it to mV it never seems to go to zero, its constantly counting numbers from 30-100 mV with the leads not connected to anything. If I change the range to .000 V it will show around .020 to .009 with the leads not connected to anything. When I tested U1 pin 1 and U3 pin 6 on my KX1 on the .000 V range I got .000, is this an ok measurement or is my DMM too screwy to use for AC mV measures? All the DC and resistance measurements with it seemed ok. thanks, -Chris ____________________________________________________________________________________Get the Yahoo! toolbar and be alerted to new email wherever you're surfing. http://new.toolbar.yahoo.com/toolbar/features/mail/index.php _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Chris:
A DVM has relatively high input impedance and will pick up stray 60 Hz and other things floating around (AM broadcast, perhaps) when the leads are open. In essence, the leads act like a small dipole receiving antenna. Short the leads together and it should read a lot closer to zero, unless you live next door to a substation or a 50 KW AM broadcast transmitter. (You can think of this as converting the leads to a loop antenna, which has a lot less pickup than a dipole.) Thus, the behavior you see is normal.

Thanks Jack,
I wasn't sure what was going on but figured it was something to do with RF in room. There's a repeater a mile or two from me and my computer and TV on so maybe that was driving it nuts. I just figured when I was asked to do the AC checks, setting the DMM to mV(actually is was on its autoscaling mode) it would show the <20mV as suggested, but instead it was going crazy. I forced the scale to .000 V and I was able to get a .002 to .000 reading on the pins so I figured I was ok. KX1 is pretty nice to build so far, in fact the KXPD was the hardest thing I've done so far. Now I will tackle the receiver circuits.

I spent a lot of time sailing as R/O in the late 1980s, running between Rotterdam and the USA east coast. 500 KHz was fun. Also spent a lot of time in the Med during that era. There were a kazillion of those tiny coastwise freighters and all of them buzzing, chirping and honking away. Heh.. Ken, I've got Mackay gear but it's more "modern". 3020A receivers out of the MRU-35 console. Even an 8050 transceiver which is still in service on many of the MSC ships. I sailed the USNS Mendonca in 2003 (part of OIF) and we had the 8050 on board. Always liked the Mackay stuff.. 73, -Doug, W7KF _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Can someone develop a K2 mod to give us (switchable) control of the CW quality - I like the rich variety of signals on these recordings. The bands these days sound a bit too perfect with all the T9X signals around! I suppose moving a large PSU near the K2 should give the AC modulation, how do we het the bullfrog on acid effect? It's much easier to copy a rough, chirpy signal in the QRM because it stands out from the norm. Some of the fists on the recordings were "interesting" too! I've just recalibrated my K2 filters to give me a widest CW filter at 1.5KHz so I can re-create the "wide open - hear everything" feel! It's HF CW field day in Europe and sitting on 20m (albeit not in great shape propagation wise) with a wide filter is great fun...
