Hello Group,
I've been running K3 #5102 in SSB phone for about 1 year using a CM500 headset connected to the rear panel connectors. For PTT Tx keying, I've been using a handswitch connected to PTT IN on the rear panel. It's worked fine. I've been away and not used my K3 for a few weeks. Turned it on tonight and found that closing the handswitch connected to PTT IN no longer puts the rig into transmit state. Disconnected the hand switch and replaced it with another RCA plug - shorted it and still no transmit state. The rig keys normally in SSB mode using the front panel XMIT button. I can't find a menu parameter that would alter the function of the rear PTT IN jack. Any ideas what might have happened? Nothing else in my hardware set up hs changed. Thanks for any help or ideas... 73, John VK7JB |

Ok, I'm putting on my curmudgeon hat here. The use of "key" to refer to
transmit/receive switching is pure, 100% CB-speak. Every time I see the Key Out jack on the back of my K3, even though I *know* it is really the PTT Out, it makes me cringe, even worse than when I see phrases like "PTT Tx keying" on the reflector. Please guys, spare me... </rant> 73, Pete N4ZR The World Contest Station Database, updated daily at www.conteststations.com The Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com, spots at telnet.reversebeacon.net, port 7000 and arcluster.reversebeacon.net, port 7000 On 4/11/2012 7:46 AM, VK7JB wrote: > Hello Group, > > I've been running K3 #5102 in SSB phone for about 1 year using a CM500 > headset connected to the rear panel connectors.

Pete,
I'm sorry to have offended your sensibilities. I was simply after some helpful, non-critical advice. John VK7JB |

The use of the word "key" or "keying" to refer to transmitter t/r keying is part is standard practice. Even one of the keying jacks on the rear of the K3 and those on other rigs are labeled in this manner.
Also, it is clearly outside of the list guidelines to make personal or derogatory comments about other posters use of language in this manner. Rants are not appropriate. Please also remember that we have a wide range countries and languages represented here. The usage of particular words and phrases will vary widely from region to region. And for those that speak a different language, the posting syntax will vary even more. Pleases treat all communications here as you would talking face to face with a new acquaintance whom you do not wish to offend. Lastly, please remember this is first a hobby.

No, it's not CB-speak. The term "key" was used to refer to
transmit/receive switching long before CB existed (1958). The term is derived from the use of telegraph keys with the first radio transmitters. Pre-1958 radio history books often include several quotes in which radiotelegraphy operators use the term "keying the transmitter." So while CBers may also use the term, it was in existence long before their service existed. So, you can stop cringing, good buddy! ;) 73, Scott, N9AA On 4/11/12 8:20 AM, Pete Smith N4ZR wrote: > Ok, I'm putting on my curmudgeon hat here.

Another thing that make me cringe is the use of 'radio' to mean a
transceiver or rig. I first heard this on CB like 'keying the mike', long before CB was around in the UK. I remember Eric saying that the XV144 would work on any radio. I could never get it to work on my old Philco.

That's right. And I object to the use of the word 'PTT', which means "Push To Talk."
That's pure phone-speak! Ain't no talking around here, just keying. :-) On 4/11/2012 8:07 AM, Ron D'Eau Claire wrote: > Way back in the early 1950's, I learned that to "key" meant to close the > (telegraph) key to activate the transmitter.

I guess I'm surprise...I'm a profesional Telecom engineer, and I always hear from other professionals and vendors, and I personally use, the term "key" when refering to the action of putting a transmitter in transmit mode. Quite an impact CB radio is making in the telcommunication world!

Well, since everyone is picking at others' terminology, I can probably
pinpoint when "radio" happened ... it's the KWM-2's "fault." I'm not older than dirt but I can remember when dirt was young, and in the OD's [Olden Days], one had a "station receiver" and one or more transmitters. I had 3 ARC-5's on 80, 40, and 20 CW. Receivers received -- transmitters transmitted, and they generally did not look anything like each other. Receivers were predominantly commercial, transmitters often not. While there were a few "transceivers" around on VHF [Gonset Communicator comes to mind], they were really just a tunable receiver and a rock-bound transmitter in one box with a handle. In land mobile equipment, both were rock-bound. Single Sideband did not arrive on the HF scene to unmitigated joy and unquestioned acceptance, as some of my equally aged friends will remember. There were lots of reasons for this, some valid, some not so much, but a big valid one was that SSB sort of required that you transmit on the same frequency that your QSO buddy was on. Depending on how you were making your SSB RF and receiving his, this was not always an easy thing to bring off. Although it had a couple of predecessors, the KWM-2 was a game changer since, without the external VFO, you transmitted exactly where you were receiving, and on the same sideband, guaranteed. Don't laugh, figuring out which sideband someone was on on a Hallicrafters SX-28 was not child's play until you got the hang of it. This was the birth of the word "transceiver" in common ham usage. Transmitters sort of faded from the scene and, unless you're Rob, K6RB who has been running his Globe King 500 on CW recently [which sounds very good :-)], they're pretty hard to find these days. Transceiver slowly gave way to "radio" which is 6 letters shorter. "Radio" can mean a specific device pertaining to radio [e.g. my K3 is a radio, as is David's Philco] and it can also mean a form of communications. It can be a noun, or an adjective [the President gives a "Weekly Radio Address," I've never found out on which station, but he apparently does]. The kids called the "closet" I used to have for a shack "The Radio Room." Radio Shack sells a few radios, and a lot of other stuff. Whether the smartypants phone in my pocket is a "radio" or not is still up for grabs, but strangely, "wireless" which is the original "radio" is now ubiquitous again. My K3, K2, KX1, FT-847, and IC-2800H in the truck, are "radios" to me. My KPA500 is a solid-state linear amplifier, and my P3 is the coolest little thing with a screen in the room. I don't think the rise of "radio" instead of transceiver had anything to do with Citizens Band, although my teen friends and I populated 11 meters when it was still a ham band since we could do just about anything there as long as we stayed in-band. And while we're at it, we were RV camping with some friends a few years ago [ours was rented], and one of them, a ham, asked me where the little notebook I kept was. I said, "It's on the rig" meaning my K2 on the picnic table. He went inside our RV [no radio] looking for it. So far as I can tell, there are no "pure" words in the English language. As Lewis Carroll wrote, "They each mean exactly what we want them to mean." 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org On 4/11/2012 8:17 AM, David Pratt wrote: > Another thing that make me cringe is the use of 'radio' to mean a > transceiver or rig. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Note that since this is English, and any noun can be verbed, "radio" can also be a verb.

Indeed, SSB was not universally accepted at first. In fact, it was met
with much derision from the AM crowd. Called "silly sideband" by some, and others who said that it sounded like a bunch of ducks quaking or someone with a severe nasal problem. Not only did one have to be exactly on the other station's frequency, but also on the correct sideband: LSB for 40m and down and USB for 20m and up. (There were no 12m, 17m or 30m allocations at the time, circa 1965.) Is there one of us from that era who wasn't embarrassed by the other operator telling us that we were on the wrong sideband? Not only did we have to select the appropriate sideband with a switch, we actually had to tune the transmitter if we changed bands or frequencies by more than about 25 kHz (kilocycles back then). This was at some risk to the finals in the transmitter, if not done quickly and carefully. Then there was the problem with either operator's receiver or transmitter drifting. There were no TCXOs back then, so it was somewhat standard practice to let the gear warm up for about 30 minutes before getting serious with a QSO. Yes, no ATUs back then, either. If you had an amplifier or antenna tuner inline with the transmitter, they had to be tuned for resonance as well. It must cause some of the newer hams to wonder how we ever made a contact in the good old days. But we did! I think it gave us a better perspective on what was inside the box, and what we were accomplishing when tuning. We've come a long way! It's great to see the resurgence in operating AM, as well as the increased interest in CW. In fact, I added the AM filter to my K3 order. 73 de Jim - AD6CW On 4/11/2012 4:54 PM, Fred Jensen wrote: > Single Sideband did not arrive on the HF scene to unmitigated joy and > unquestioned acceptance, as some of my equally aged friends will > remember.

> Indeed, SSB was not universally accepted at first.... ================= That's for sure. There were very entertaining SSB vs AM wars on the high end of 40 meters (and I think on 80 too), back in those pre-CB days when all hams used the word 'key' to refer to pressing PTT. One of the most memorable icons of this battle was the fantastic AM transmitter at W3PHL, described in an article in the Feb 1963 issue of 73 magazine. You can find pictures of it on line, and maybe the article too. The passbands of receivers were a funny shape in those days, and the BFO was separately tunable. Magazines had articles explaining how to tune in the new mode; I remember one in QST that had an illustration showing a bunch of ducks flying out of a ham speaker, all wavy and distorted. Then the befuddled op followed the instructions in the article, and the next illustration showed the ducks looking happy as they flew out.

Callsign restructuring occurred in March 1978. 2X1, 2X2 and N-prefixed
1X3 callsigns would've become available nationally at that point. AA-prefixed 2X2 calls had been used during the U.S. bicentennial and were released to areas that had run out of "preferred" (Extra) calls. N-prefixed 1X2 calls were released about the same time, in approximately 1977. 2X1 calls didn't become available until '78. The first time I heard on on the air was AB9W, who got quite a bit of ribbing for having a "backwards- literally, if you look at it- callsign. 73, Scott, N9AA On 4/11/12 11:31 PM, Ron D'Eau Claire wrote: > Ha, ha!

In 1965 I was a tech so was restricted to 6m and up. I mostly was on
2m which at that time I was allowed on 145-148 MHz. Virtually all phone (voice) was on this segment at the low end. I had a Johnson 6N2 (5894) and ran a Johnson Ranger-II for PS and modulation (AM). I had a Clegg Interceptor-B which was one of the first VHF SSB receivers so I could tune in 144.064 MHz which was the 2m-SSB frequency in the mid-west. I had a xtal for that freq. so I could talk with the SSB guys by running AM. Later I swapped for a DX-100 to supply plate modulation running two 1625's at 120w audio which should have over modulated the 5894 but the mod transformer was mismatched enough to load down the modulator at 150w RF output. My xtal frequency was stabile enough for the SSB guys. I "keyed" the radio by throwing a transmit-stby switch on the receiver which controlled the Dow Key coax relay. The relay had auxiliary contacts which keyed the transmitter. Most transmitters of that time had simple mic connectors with no PTT switch contacts. The transmitter keyed either via the CW Key jack or some pins on the octal aux connector (remember those?). Two controls for the final: LOAD was peaked for plate current and TUNE was dipped for plate current (or do I have that backwards?). That got the final about to resonance and max output. I only lost one tube during those years. Back in my Novice years on 40m I tuned CW or SSB by advancing the regen control on my 3-tube "Ocean Hopper" receiver until it went into oscillation. I had my CW Key connected across the speaker to run the receiver like a code practice oscillator. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?
