Re: [Elecraft] Microphones (was electronic product standards)
I read years ago that speech processors like pre-emphasized audio (louder highs, quieter lows). And the heavier the processing the more pre-emphasis is optimum. Does anyone know if the K3 speech processor does that automatically?

RE: [Elecraft] D-104 and Radio Shack electret element
The Astatic crystal element exactly fits the "lollipop" housing. It's THAT big! But it's no problem to remove and rewire. The lollipop top even unplugs from the stand. Unlike a lot of "modern" desk and hand mics, the D-104 was designed around the element, rather than coming up with a design for the case and plunking the element inside! That was true of most of the old microphones. For example, the Heil "Heritage" microphone is a copy of the old "ribbon" microphones used for broadcasting in the 1930's and 40's. The long, tall shape of the enclosure was dictated by the shape of the microphone inside, which used, literally, a ribbon of flexible metal in a magnetic field. Another enclosure for the same ribbon element is the Heil "Classic" that was another 'standard' in broadcasting studios everywhere. In both cases, the "pop" screen so often seen put in front of the microphone today is part of the mic and dictates the separation from the grille and the element inside. It's placed just inside the metal openings. Similarly, the more round mics were either miniature crystal elements or dynamic elements which were that size! Heil has used these designs for good reason. People associate those mics with quality and performance, based on old associations. Heil can use them because today's elements are so small they can be put inside almost any "traditional" enclosure. Even the most "technical" of us still responds to "fashion" -- at least some of us do. Ron AC7AC -Original Message- you might be able to place an electret element in the case and leave the original element in there You'd have to rewire since the astatic has a 3 conductor plug on the mic housing. I have placed an electret ( small ) in front of a dynamic AKG element in my current station microphone, and cannot hear any acoustic interference. bill ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 8R/keyline-RF Timing Questions
Steve I measured this a couple of years ago and put the info in my notebook. As you mention, 8R transitions 15 ms before rf output. It doesn't transition back again until 5 ms after rf has stopped. The timing is completely independent of the t-r value set in the primary menu. I tried it with t-r=.02 sec and t-r =1.0 sec and the timing was the same. This was in cw mode. I don't have measurements for ssb. I used the info to see if I needed to make external timing circuits for a hb transverter I was building. I didn't. And the transverter works fb. (I did use fast relays though) Hope this helps. 73, Lenny W2BVH Steve Kavanagh wrote: I read on this forum that there is about 15 milliseconds delay between the transition of the 8R line from receive to transmit (and hence of the key out lines in the KPA100 and K60XV) and the beginning of RF output. I have a couple of questions with respect to this delay: (1) Does this apply on both CW and SSB ? (2) What happens on the transmit-to-receive transition ? Does RF cease before or at the same time as the 8R line or is there a similar delay ?

Depending on the hardware, it is entirely possible for two devices to be sending on the bus at the same time with the local data masking the remote data. There are no hardware differences involved - a serial bus with one device trying to pull the bus low & another device trying to pull the bus high will result in at least one device not seeing what it was expecting to see on the bus.

Hopefully you won't think I "cheated", but I put a message in one of the memory cells to use for calling. Working a pile-up can get a bit tiresome sending by hand all the time. So I put "DE W7AQK W7AQK W7AQK K K K" in memory to do my calling. Then when VP6DX came back (after several tries) I retuned using the paddle.

RE: [Elecraft] K3 Convergence
W4TV continued: > CI-V also allows for multiple controllers, though I > have yet to see any other application that appears > to properly implement its CSMA/CD protocol. There is no carrier switching or collision detection in the CI-V protocol. The data packets do not carry any checksum or sequence number both of which are required for CSMA/CD. CI-V is a pure aloha protocol - if the packet gets lost or damaged the originator must resend if it does not get the expected reply. CI-V does have collision detection, as every device can see the serial bus as it sends. That also makes a checksum unnecessary. It is intended that a controller resend a command if a collision is detected, so there is no need for sequence numbers, either. "Carrier sense multiple access with collision detection" does not mean any more than that - but what I was responding to was the assertion that "there is not a single radio that is capable- in either hardware or software - of reliably servicing two different radio control applications". Maybe there isn't, especially if one insists on not working with the radio as the manufacturer intended. 73 & HLNY, VR2BrettGraham. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

On the other hand, while waiting for a reply I snagged VP6DX on 17M at about 22:55Z with my trusty K2 for my first QSO with them. 73, Mike WA3KYY K2 #2221 K3 #379 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I've only ever used it on rare occasions when I've taken the K2 out mobile or portable, but it sure has earned some unsolicited complimentary audio reports. As for plug compatibility, my oldest mic has been rewired so many times the cross-head screws on the plug shell are almost completely burred over. Fortunately since the K2 arrived in the shack several years ago I haven't needed to rewire it.

One of the things it mentioned is that the program apparently doesn't work well if any filtering is used. It wants a wide band input taken from the IF, not a regular audio output, or its decoding abilities suffer. Don't ask me why. It's most depressing, reading how the software helped the author spot the exact frequency that successful callers were using, so he could call on the same frequency and make a contact with the DX right away, while others without the software, unable to spot the exact frequency to call on, went unanswered. A key skill that allowed the less well equipped station to get an advantage over those with more power but less operating prowess, has been wiped out by a bit of shareware. :( (To forestall a possible deluge of requests for copies of the article, sorry but I don't posssess a scanner, even if I was willing the RSGB's copyright.) - Julian, G4ILO K3 s/n: 222 K2 s/n: 392 G4ILO's Shack: www.g4ilo.com Zerobeat Ham Forums: www.zerobeat.net/smf -- View this message in context: http://www.nabble.com/Decode-1-signal-only-tp15473995p15491147.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 NEED HELP TROUBLESHOOTING
Rich, I suggest you look closely at the connectors between the control board and the RF board for a poorly soldered or unsoldered connection. Especially pins 35 and 36 of control board P2 and RF board J7. Also pins 1, 2 and 5 of control board P3 and RF board J8. These latter AF control pot lines go to RF Board P1 pins 1, 2 and 3 and Front Panel board J1 pins 1, 2, and 3. The reason I suspect an unsoldered connection is that you caused the problem when you removed/re-installed the control board - and in the process, something moved. An unsoldered connection can work just by physical contact for a while, but will break the connection if it is moved. You can use your ohmmeter to check continuity along all these paths - use the schematic to see where the wire starts and ends up. 73, Don W3FPR RICHARD MC KINNEY wrote: I removed the control board as suggested in 065 of the guide.

Re: [Elecraft] Not All Hams are Technicians (WAS: Microphones)
I very seldom post to this list - taking up even more bandwidth doesn't seem to be what the list needs lately Hi, but this thread sparked a response so I thought I'd share it. Although I was into CB in a big way "back in the day" (when it was as polite and compliant as we sometimes wish amateur radio was today), college, career, and family intervened until 2006 when I finally became licensed at age 44 (passed my General in 2007, shortly after rushing to pass the code before the requirement was eliminated). At that time I was one of those "interested in operating with the best equipment my budget could allow," but I had/have no real electronics experience, other than doing all my own soldering when needed and one summer as a teenager when I worked for a neighbor who was in the process of inventing the first automated wire-wrap assembly line jig. I still remember him trying to beat Ohm's Law into me, without much success. Since becoming licensed, I actually find the pursuit of learning electronics more attractive than operating, most of the time. I seem to be in love with QRP, mostly because of all the opportunities to build. I still don't know what I'm building, but I'm doing everything I can to read, question, and study, and hoping that repetition will help! Currently awaiting my attention at the bench are a Pixie II, a Norcal SMT dummy load, one of each of everything Hamgadgets sells, and a BLT tuner. My goal is to use each as a learning project, taking my time with each one and understanding the purpose each component serves before moving on to the next. The recent QST article "Building to Learn" couldn't have been more timely. I couldn't wait to build my KX-1 last year, and it turned out great (with some help from Don on the 3080 board!), but I have to admit that my approach did not make it a learning experience. The hurdles these days are time, and access to a willing Elmer who doesn't mind teaching stuff that he's known for 50 or more years to someone new. -- 73, de Mike, KC0KBC -- Original message -- From: "Ron D'Eau Claire" <[EMAIL PROTECTED]> > Agreed Dave! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I personally would not intentionally transmit a "wide" signal during a contest. It would, imho, be counterproductive, apart from any other reasons. On the small 40m band in Europe, during large contests, you almost can not avoid stations sitting on top of each other and/or overlapping. Even if I assume that there were no BC stations between 7100kHz and 7200kHz and that a channel is only 2.5kHz wide, between 7040kHz and 7200kHz one only has space for 63 running stations without any conflicts arising, or using the older limits of 7040kHz to 7100kHz space for 23 SSB signals. Here there will always be a certain amount of elbowing going on. If one considers all the high powered phase noise being radiated and so on, then even a 9+20 signal can be a weak signal when compared to "40m contest noise" levels. And finding gaps between stations can be a real art. This is why you want to have a signal with a very high average power level, but one which is also not wider than necessary. vy 73 de toby ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Not All Hams are Technicians (WAS: Microphones)
Agreed Dave! Hams are not necessarily electronics technicians or engineers. Many simply want to operate with what they feel is the best commercial gear their budget will allow. They are just as much Amateur Radio Operators as the guy who designs his own rigs from scratch. We've always had that disparity among Hams. Decades ago, before "radiosporting" was popular, those operators were largely traffic-handlers in the days when a telephone call to a city 100 miles away was both expensive and difficult. Hams offered an excellent way for people to pass non-critical messages quickly and efficiently for free and usually much faster than the post. You can go all the way back to the days of spark and find ready-made equipment for those who do not want to build their own gear. They've always been an important part of the hobby. When I got on the air, there were hams with fully factory-built stations from time-honored manufacturers like Hallicrafters, E.F. Johnson, Collins, National, Millen and many others. There were microphones like the venerable D-104 and dozens of others that plugged into the rigs for phone and keys that plugged into the rigs for CW. And, back in the 1950's, some homebrewers were pretty arrogant about the 'appliance operators' on the bands who couldn't read a schematic or build their own gear. Some things never change, Hi! Being able to pass a test for the license and the competency and confidence that comes from actual hand's-on experience are two entirely different things. Those who pass the test might not wish to tackle actually putting that information to work in their shacks. The challenge comes with those who have the interest and are still developing that experience while learning. Every technician and engineer today has passed through that period, whether they are amateurs or professionals. A key part of Ham radio has always been for those who can to help. It's what this reflector is all about. It's what companies like Elecraft are all about, providing kits for those who want to build but who lack the knowledge, time and equipment to do their own design work; kits for fully-functional rigs to simple test equipment to help them built up their shop. We might be seeing a slight shift in the membership here now that Elecraft is providing "factory built" rigs, but that's been the case of other famous Ham rig manufacturers like E.F. Johnson. All it means is that Elecraft is addressing more of the Ham community with their products. For someone wanting an "off-the-shelf" microphone, Elecraft provides one for their rigs. Perfect "plug 'n play". Ron AC7AC -Original Message- I know that there has been lots of responses to the microphone compatibility on this forum but let me comment on this subject on a different light. When I first became licensed back in 1957 we were expected to, at the very least, be able to read and interpret schematics, wire up our own rig interconnections, and in a lot of cases build our own equipment. Now days that is not necessarily true for quite a few of our fellow radio amateurs. Because of the above, it can be quite a challenge for some of us to perform the necessary research and rewire our mike connectors for the Elecraft K2/K3 rigs. Many of us would have no problem doing this but we can easily forget that there are those who are dependent on getting the correct mike for the rig or have help in changing their connector's wiring to match a rig. Manufactures are little help as they wire their mic jacks to what pleases them and it is their right to do so. The bottom line is lets help those who need it and not criticize them. and for those who need help get it here or ask a fellow ham. 73 Dave KD1NA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] CW with my new k3
Hi Joe, Your K3 is working normally. When in CW mode you must have VOX turned ON to "enable" CW output power while keying regardless if QSK is selected or not. In this case, while in CW mode, it is semantics. On my 7800 Icom makes a distinction. When in SSB mode it's called VOX and in CW mode it's called BK-IN (Break-in).

I made my own 'filling' for the much smaller sized element, but Heilsound does sell a kit for just that purpose. Just use connectors for the AF and PTT that mate with the K3 rear connectors and you should be all set.

Re: [Elecraft] K1: Inp Menu Item Pdn Only Allows Dits
I can guess at 2 possibilities - one is that there was something sticky on the shell of that mono plug which adhered to the wiper in the paddle jack - it only takes a bit of something like the adhesive from electrical tape to do that. The second is that somewhere along the dash signal line, you have a bad solder connection that made contact when it was touched. If you have trouble again, I suggest checking the schematic for everything connected to the dash signal (including connectors) and re-flow the solder. 73, Don W3FPR MGFoster wrote: I turned on the K1 & tested to see if the problem still existed - it did.

[Elecraft] Microphones
I know that there has been lots of responses to the microphone compatibility on this forum but let me comment on this subject on a different light. When I first became licensed back in 1957 we were expected to, at the very least, be able to read and interpret schematics, wire up our own rig interconnections, and in a lot of cases build our own equipment. Now days that is not necessarily true for quite a few of our fellow radio amateurs. Because of the above, it can be quite a challenge for some of us to perform the necessary research and rewire our mike connectors for the Elecraft K2/K3 rigs. Many of us would have no problem doing this but we can easily forget that there are those who are dependent on getting the correct mike for the rig or have help in changing their connector's wiring to match a rig. Manufactures are little help as they wire their mic jacks to what pleases them and it is their right to do so. The bottom line is lets help those who need it and not criticize them. and for those who need help get it here or ask a fellow ham. 73 Dave KD1NA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: Re: [Elecraft] Microphones (was electronic product standards)
I've heard it said that some contest stations deliberately transmit a wider-than-necessary signal to keep competitiors away from "their" channel. I personally would not intentionally transmit a "wide" signal during a contest. It would, imho, be counterproductive, apart from any other reasons. On the small 40m band in Europe, during large contests, you almost can not avoid stations sitting on top of each other and/or overlapping. Even if I assume that there were no BC stations between 7100kHz and 7200kHz and that a channel is only 2.5kHz wide, between 7040kHz and 7200kHz one only has space for 63 running stations without any conflicts arising, or using the older limits of 7040kHz to 7100kHz space for 23 SSB signals. Here there will always be a certain amount of elbowing going on. If one considers all the high powered phase noise being radiated and so on, then even a 9+20 signal can be a weak signal when compared to "40m contest noise" levels. And finding gaps between stations can be a real art. This is why you want to have a signal with a very high average power level, but one which is also not wider than necessary. vy 73 de toby ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] VP6DX on 160 Elecraft Mojo
Worked VP6DX this morning on 160... I was running my K2/100 (about 90 watts to the tuner due to some foldback issues) thru the KAT100 into a 55' piece o' wire with a few radials, none any longer than 40'. It was a solid no repeat QSO. Those folks have good ears and they were a solid copy without a Rx antenna on the K2. Don't be afraid to try them, even if you think your antennas are lacking. Worked them on 12M CW as well, been ages since I even heard anyone on 12! GL to all in ARRL DX this weekend. It's looking like a Low Band show. 73, Julius Julius Fazekas N2WN Elecraft K2/100 #3311 Elecraft K2/100 #4455 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Convergence
Yes, Simon is describing what I had in mind - a software solution that can be implemented in the near future. Lacking such an RS-232 server program, we're left only able to run one CAT-capable program at a time. Unless your contest logging program implements its own version of cw skimmer or clickable panadapter etc, we won't have these capabilities unless software that will arbitrate access to the serial port from multiple programs is available. 73, Barry N1EU Simon Brown (HB9DRV) wrote: > > Taking things a step further - it would not be at all difficult to allow > other programs to send K3 commands to / from the K3 through another > program. > > This program (server) controls the serial comms and supports an unlimited > number of clients.

Re: [Elecraft] Microphones (was electronic product standards)
Thanks for posting your interesting comments Brendan. Within the context of SSB useage in ham radio I believe that the 'hype about audio' could lead to another related problem, if not already existing, which is poor use of the HF spectrum available to us. Given the proven fact that a SSB transmitter filter bandwidth of 2.1 kHz will result in the transmission of a very 'good quality' speech signal, provided that the carrier is positioned properly and that the mic - audio - modulator system characteristics suit human speech, I see no valid reason for using wider SSB filters. In addition to the increased amount of spectrum used, the use of wider filters followed by linear amplifiers whose IMD products might be only 30db or so below a test tone obviously results in a wider 'Interference Bandwidth', and should be discouraged IMHO. Adding Reverse ALC to the mix can further increase interference. Just an opinion. 73, Geoff GM4ESD Brendan Minish <[EMAIL PROTECTED]> wrote: These words (in ham radio use anyway) have become marketing speak and now mean nothing.

[Elecraft] OT: FS, Icom IC706MKIIG
Early birthday present - My IC-7000 will be here either Friday or Monday. My 706MKIIG is up for sale. It's several years old, in great shape, has never been in a smoking environment and just snagged Ducie island on 160 meters this morning. It comes with the original stuff (power cord, mounting bracket, separation kit including the remote head mounting bracket etc. Original microphone (not the Touch Tone mic). My wife accidentally threw out the original box, but I have the manual and will throw in a copy of the maintenance manual that I downloaded and printed as well. Gonna order my K3 with my tax refund & rebate. Asking $525 shipped anywhere in the US. Contact me off list if interested.

Re: [Elecraft] K3 Convergence
Taking things a step further - it would not be at all difficult to allow other programs to send K3 commands to / from the K3 through another program. This program (server) controls the serial comms and supports an unlimited number of clients. The clients speak to the radio using the radio's native protocol through the server. It's a simple concept, the programming is not too difficult except when talking with some of the older Yaesu radios. Supporting the K3 / Kenwood / ICOM like this would be simple. As for things like split mode - as far as I can remember no ICOM radio supports this via CAT commands, not even the $10k+ IC-7800 :-( Simon Brown, HB9DRV -- From: "Joe Subich, W4TV" <[EMAIL PROTECTED]> No, every program needs to know the radio status at all times.

Today Paging Microphones are still specifically designed to have this pronounced mid range presence peak and also usually include Quite a bit of low frequency Roll off Shure have a range of dynamic elements available for this market, that have response curves that look remarkably similar to the HC4 and HC5 elements. take a look at the response curve of the Shure 450 http://www.shure.com/ProAudio/Products/WiredMicrophones/us_pro_450SeriesII_content a direct link to just the curve http://www.shure.com/groups/public/@gms_gmi_web_us/documents/web_resource/site_img_us_rc_450series2_larg.gif the 522 has a broader presence peak http://www.shure.com/ProAudio/Products/WiredMicrophones/us_pro_522_content Direct to curve http://www.shure.com/stellent/groups/public/@gms_gmi_web_us/documents/web_resource/site_img_us_rc_522_large.gif elements for these mics (and many others) are available at low cost as replacement parts. Heil sound plot their curves on a different log scale but after accounting for that the similarities are remarkable. http://www.heilsound.com/amateur/products/hc4/index.htm The needs of paging systems which include efficient use of limited power and maximum intelligibility in noisy environments are pretty much identical to our requirements for effective SSB modulation. Any well made paging/ Dispatch mic (or element..) is ideal for amateur radio use, most are far more durable and cost effective than 'the made for ham radio' stuff that is popular these days. > Even the "high end" Ham mics only offer general and > uninformative comments about "shaping" and "clarity" that say much and > convey little.

If you are looking for flat then these are a great place to start, however the design of the housing may have quite an impact on how things sound, this can be used to your advantage to create a presence peak or LF roll off. My own headset is based on a salvaged electret condenser mic with some audio tailoring done by means of a simple R/C filter, being lazy I copied the circuit of an Icom handmic. It works great and cost me almost nothing. 73's Brendan EI6IZ -- Don‘t complain. Nobody will understand. Or care. And certainly don‘t try to fix the situation yourself. It‘s dangerous.
