Re: [Elecraft] O.T.: End of (another) era
Good morning from this side of the pond. People have been predicting the demise of CW for years but, certainly over here since the removal of the necessity to pass the code test to get a licence the amount of Amateurs learning the code seems to be on the increase. Certainly at the clubs around here CW lessons are well subscribed. I wonder if our friend in Alaska is a CW op or has ever learnt it?.

Re: [Elecraft] O.T.: End of (another) era
Well I hope not guys. I bought a keyboard and connected it to the SVGA in the P3 so I could send some perfect code for a change. It felt like I was cheating, but it sure sounds nice. The elements of the characters are perfectly spaced, as are the characters. I can log while the memories play. I can switch to the keyer at will.

Re: [Elecraft] USB to RS232 cable or adapter
While searching for a new hub recently I came across one I had not seen before. I had been using 2 7 port hubs but had ran out of ports on them, yes I have a lot of things on the desk requiring several USB ports. I was looking at the Manhattan web site as I had used them for some time because of their Lifetime Warranty. It was there I found the USB Hub 28 ports total 14 plug in on the top and 14 on the sides. Each port has its own lighted switch so that each port can be turned on or off easily. 4 of the posts are USB3.0 the remaining 20 USB 2.0 your computer does need at least 1 USB 3 port to have them on the hub. I am currently using 18 of the ports and finally able to have most all hooked up at one time. The hub is extremely well built and works perfectly I wish I had found one like a long time ago. It retails for $99 but I found mine online at Amazon.com for $58 free shipping. It you need a large hub with switches to turn ports on or off this is it and as always it has their Lifetime Warranty. 73, Fred/N0AZZ K3 Ser # 6730--KX3 # 2573--K2/100 # 6470-KAT100 P3/SVGA--KPA500--KAT500--W2 -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jack Berry Sent: Monday, July 15, 2013 6:52 PM To: Alan Hawrylyshen; k...@att.net Cc: Elecraft Reflector Subject: Re: [Elecraft] USB to RS232 cable or adapter I opted for an 8 port adapter.

Re: [Elecraft] O.T.: End of (another) era
Hi All, Ed may be right--it's hard to say. It also depends on what the definition of disappear is, meaning I think there will always be some adventurous souls using CW regardless of where technology takes us.

Re: [Elecraft] O.T.: End of (another) era
I operate the RSGB demonstration station at Bletchley Park (GB3RS), I tend to operate mainly on CW, young people are absolutely fascinated by CW. I had one young lad left with me for 2 hours while his family went on the museum tour, all he wanted to know about was morse!. I showed him the WEB SDR at the Uni of Twente in Holland, hopefully the spark was generated and he will be one of the new generation of CW ops...

Re: [Elecraft] KAT500: Tuning on 6m
Jim Brown-10 wrote If I put KAT500 in BYP, the K3 often shows SWR's of 2 to 3. If left in AUTO, the mismatch is apparent in received audio. Without the KAT500, the antenna itself exhibits a 1.3 SWR consistently . Many tuners add SWR even in bypass because the path through is not 50 Ohm. It is easy to check. Set a tuner in bypass, add a dummy load, and scan SWR. Usually SWR increases rapidly with frequency. Like 1.1 on 20m, 1.5 on 10m and 2.0 on 6m. This causes unnecessary matching when in automatic mode. The best way around this is to add a cap on the tuner input. Find that value that minimizes SWR on 6m. Usually it is 10-30pF. The cap needs to be big enough to handle power but not too big since the voltages are pretty low at low SWR ( 200V at 500W level).

Actually, the fundamental cause is that those tuners use the chassis as the signal return, which adds inductance to the path. The switching relays also add inductance. A proper path would be all coax (or another form of transmission line). This doesn't matter much at HF, but it begins to be significant at 6M. I've measured the KAT500 with a VNA. I don't recall numbers, but the SWR is VERY low at 50 MHz. While adding the capacitor you mention certainly works, there's no need to do this with the KAT500. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KX3 VFO B Alternate Display ?
Phil, That is correct. The battery '+' and external supply '+' are connected together. The voltage at the battery's negative terminal is measured and subtracted from the voltage at the '+' side. So with no batteries installed, 0V would be read at the batt '-' side. And when no external supply is connected, BT and PS will also read the same. This is all related to how the battery and external supply are isolated from each other through the diode 'OR-ing' circuit that allows the higher voltage of the two to power the radio. 73, Rich AC7MA On 07/15/2013 09:33 PM, Phil Hystad wrote: On the KX3 VFO B Alternate Display you read Time, Power Supply Voltage, Battery Voltage, and so forth. So, my question is regarding the BT (Battery Voltage) display. I assume that this reads the same as the external power supply voltage level (PS) if there are NO batteries in the battery holder. I never paid too much attention to this before and I have had batteries installed almost from the time I put the KX3 together so I have not noticed this before. So, can someone confirm that if no batteries are used that BT shows the same reading as PS? I can understand how this might make some sense but I think I would prefer that BT show zero volts (or, N/A) or something if no batteries are installed.

I expected only passable performance...but AM and FM broadcast band performance is better than anything I've used in 45 years as an avid AM listener (and FM is equally impressive). The 390 is noticeably better than the 380 on AM. It is a wider radio than the 380, so it has room for a significantly longer ferrite rod antenna. It also has FM stereo and a very handy line-in jack, both of which the 380 lacks. The Tecsun ... radios run on AA batteries or a wall wart... I found it better to use NiMH rechargeable batteries and take advantage of the built-in recharge-from-USB circuitry. The radio allows one to specify that NiMH cells are installed instead of normal AA-cells. The 390 comes with a case with bottom pocket to store: (1) Stereo ear buds, (2) USB charging cable, (3) Clip-on wire antenna, (4) 3.5mm stereo cable to connect an external AF device to the 390's line-in jack (Great for using with an MP3 player). I also own three of the GE Super Radio III, which is one of the best AM broadcast receivers around. I have an *original* Super Radio (not model II or III), plus a model III. My original model always performed much much better than the III, but the model III had a terrible history of significant QA problems. All are very large portable radios by modern standards. My small Tecsun 380 and 390 grossly outperform these old units. I haven't been much concerned about the AM broadcast performance of the KX3. When a rather small SDR AM/FM broadcast radio like the Tecsun 390 is available at trivial cost, I don't require a ham rig to attempt to match it for broadcast reception. There are now many SDR radios available for give-away prices that have outstanding performance, ranging from these Tecsun BCB receivers to the Baofeng micro-size VHF/UHF HTs. Both are useful SDR-technology radios to supplement the SDR KX3. 73, Mike / KK5F __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] The KX3 as a shortwave broadcast receiver
I'd agree with you about the Tecsun radios, Jim. I bought a PL-660 last year, before Christmas. The only gripes that I have are: a) the cheap Chinese batteries that came with it had a short life. I topped off the charge after installing the batteries, and the next time that I tried to use the radio, they wouldn't take a charge. b) no BFO. I was going to listen to the Night of Nights transmission Friday night, and I discovered the hard way that it doesn't do CW.

It takes skill! That is what seems to be disappearing from ham radio! Look at the decline in the ability of the average ham to build his/her own gear, let alone repair it! Admittedly, the radios we buy these days don't lend themselves to DIY repair, mainly due to the advanced technology of things like SMD's, etc. These days, if you have a problem, it usually means swapping out an entire board rather than replacing a single part. This is one reason that I didn't pursue electronics as a career. Back in the early 70s I was in the Air Force, working on FAA-style air traffic control radar systems. One unit that I worked on was tube-based, with probably 100 or more adjustments to keep it properly aligned (per channel - there were two of them). While the most common cause of problems was tube failure, we were required to troubleshoot and repair to the component level. Fast forward a couple of years, and we had installed a completely solid-state/digital auxiliary system. The only adjustment was the +5V; not that we ever had to touch that after installation. If anything failed, we had a flowchart to follow to determine the most likely *board* that was the problem! Power down, swap the board, power up, see if the problem disappeared. We were specifically prohibited from attempting to repair these boards in the field. The absence of a mandatory level of CW proficiency has clearly reduced the level of CW activity--except in contests! Interestingly, though, now that CW is no longer mandatory, a lot of newer hams (and some old ones too) seem to be having some sort of epiphany about the virtues of CW, and are voluntarily taking it up. Very interesting!!! I'm no psychologist, but it seems that humans respond more favorably to discovering things on their own, rather than being forced to do so. Heck, as afar as I'm concerned, anything to further my favorite mode of communication on the radio. The bottom line is that technology is apt to change everything! It might even substantially wipe away ham radio all together! It certainly has distracted newcomers who now seem to be nearly totally focused on computers. I have some serious concerns about the survival of ham radio itself, but for now, I think the biggest threat is CC R's! Hi. You got that right! It's becoming almost impossible to find a new home without CCRs. We're planning a final move in the next few years, possibly to KH6-land. My two challenges to the realtor: no CCRs and no HOA.

Re: [Elecraft] O.T.: End of (another) era
I don't know how long this thread will be tolerated, but I will try to add a few comments (mainly to Dyarnes w7...@cox.net): Definition of ending or disappearing is subjective, at best. Sure there are a few AM enthusiasts out there but one would not really consider AM as a thriving active mode. Maybe a test is to see how easy it is to find a station running a mode. You can hear CW almost any time of the day on a daily basis (unless a CME has destroyed the ionosphere). Use that same test on AM. Also AM has not disappeared from commercial use like CW: Still in use on BC band, Shortwave broadcast, and for VHF aircraft. But there are plenty examples where morse code has be discontinued. I don't expect CW to disappear overnight from ham radio, and like the rebuilders and restorers of Old radios may linger on indefinitely. But with the exception of high power transmitting, tubes are history. And this hold-out is under attack by LD-MOS technology for high RF power amplifiers. I still use a 8877 for QRO on 2m-eme but probably would not start building one today in favor of building a $250 LD-MOS 1200w amp that drives with 3w and only requires 50v vs 4kV. Technology! Regarding digital modes and their conversation ability: psk-31 and rtty both are nice for this. JT65 was not designed for messaging. It was designed to handle the minimum information required for a valid eme contact. EME is not conversational for most stations (there are a few big-guns that can carry on a conversation using CW). But JT65 can be modified to handle plain text messages so not functionally impossible. The recent creation of JT56HF and use on HF would predict such as forthcoming. The objection to digital is to its not being a real-time interactive experience, yet many of you participate on chat rooms. Keyboarding is an alternative how ever it is technically accomplished. The real truth is many on this reflector are avid CW operators and like it. So why justify that? I like eme...you do not have to. I like designing and building smt level stuff...you do not have to. You like CW... It really comes down to whether CW will attract new blood. That must happen for it to survive as an activity. No one can predict the futureyes, that is all BS! But that is one of the fun things of ham radio...BSing (chewing the rag, whatever). Final note: I got my Novice license in 1958 and did learn CW; later passed my General, Advanced, and Extra. I also hold a 2nd Class Radiotelephone with radar endorsement. 45+ years in electronics as a professional. I own all that to ham radio which captured my imagination at age 12. How well is ham radio doing with youth, today? 73, Ed - KL7UW http://www.kl7uw.com dubus...@gmail.com Kits made by KL7UW __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] OT: AM mode

Ken wrote: AM aircraft radio has been around since the end of spark and steadily growing world-wide since that time. It was solidly in place -long- before FM was a gleam in Armstrong's eye. Er...I'm not sure how that supports an argument that transition to FM was *at any point and time* considered *by any responsible party* to have characteristics that were more desirable than AM for aircraft communications. The characterization that AM was solidly in place -long- before FM was a gleam in Armstrong's eye refers accurately only to the era when aircraft communications were only on medium and high frequencies... an era when long-range aircraft communications often still made use of Morse CW (hence the FCC Element 7 exam for Aircraft Radiotelegraph Endorsement, now discontinued). The transition from MF/HF to VHF for aircraft communications received its greatest push with the UK's pioneering use after 1940 of aircraft AM command sets operating in the range of 100 to 156 MHz. This sparked the allied US military's transition from MF/HF command sets to VHF command sets, one of the earliest being the Western Electric 233A set. At this point, VHF FM could have been *very easily* adopted, had it not been for its undesirable capture effect. Aircraft VHF-AM was chosen long after FM had been developed. The decision to use AM was purposely made. The adoption of aircraft VHF-AM was NOT the result of constraints from earlier legacy technology. All civil aviation eventually adopted the military standard of VHF-AM, although up to the mid-1950s many private aircraft continued to use MF/HF sets with receivers in the 200 to 400 kHz range and a transmitter on 3105 (later 3023.5) kHz...still far from a universal commitment to VHF-AM at that late date, had VHF-FM been a better choice. Further, by 1945, the US military began exploring UHF for aircraft comms. These new sets had no reason to stick with AM, if FM were superior. But FM was not superior...or as good. AM was chosen for use in the military UHF aircraft band as well. It remains that the staggering cost of conversion to FM is the real reason it continues today.

[Elecraft] FS/Trade HP 8921A+83236B
I have a nice HP 8921A service monitor with TrackGen, and all options including an 83236B cell phone test adapter. Works great, but I'm needing a smaller lighter box like the CMS-51 or -54, or an IFR 1200S. I end up doing most of my stuff from a car or in the field, as I do some consulting and use this for both the ham bench and for minor consulting / engineering gig's. Anyone have an interest in the HP, or even more enticing, a smaller / slightly less capable Service Monitor they'd like to trade ?

It was solidly in place -long- before FM was a gleam in Armstrong's eye. Er...I'm not sure how that supports an argument that transition to FM was *at any point and time* considered *by any responsible party* to have characteristics that were more desirable than AM for aircraft communications. The characterization that AM was solidly in place -long- before FM was a gleam in Armstrong's eye refers accurately only to the era when aircraft communications were only on medium and high frequencies... an era when long-range aircraft communications often still made use of Morse CW (hence the FCC Element 7 exam for Aircraft Radiotelegraph Endorsement, now discontinued). The transition from MF/HF to VHF for aircraft communications received its greatest push with the UK's pioneering use after 1940 of aircraft AM command sets operating in the range of 100 to 156 MHz. This sparked the allied US military's transition from MF/HF command sets to VHF command sets, one of the earliest being the Western Electric 233A set. At this point, VHF FM could have been *very easily* adopted, had it not been for its undesirable capture effect. Aircraft VHF-AM was chosen long after FM had been developed. The decision to use AM was purposely made. The adoption of aircraft VHF-AM was NOT the result of constraints from earlier legacy technology. All civil aviation eventually adopted the military standard of VHF-AM, although up to the mid-1950s many private aircraft continued to use MF/HF sets with receivers in the 200 to 400 kHz range and a transmitter on 3105 (later 3023.5) kHz...still far from a universal commitment to VHF-AM at that late date, had VHF-FM been a better choice. Further, by 1945, the US military began exploring UHF for aircraft comms. These new sets had no reason to stick with AM, if FM were superior. But FM was not superior...or as good. AM was chosen for use in the military UHF aircraft band as well. It remains that the staggering cost of conversion to FM is the real reason it continues today. That is a gratuitous assertion for which my decades of study in this area finds no substantiation. 73, Mike / KK5F __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Relay boards for remote control?
I have used the denkovi 16 relay set and the 8 relay set with ethernet access to design and build a controller which automatically selects either my normal antenna for each band or an alternate antenna for that band. I use the K3's BCD outputs to determine the band, and a arduino programmed to decipher which relay to kick in. The unit also will switch my two radios over to a dummy load (all done through relay switching of 12 volt lines). I use the ethernet module to control the relays when I have a radio in my living room (as opposed to the one in my shack). With the denkovi relays, you can choose from ethernet controlled, USB control, or serial control, and they have some excellent software for each module. The ethernet module has a built-in web site which you can set up to access from your computer. I have not found any negatives with these units. They are well-built and well documented.

Re: [Elecraft] Relay boards for remote control?
Hi, I wondering about the USB versions. They have a caution in the docs about a power cycle, which causes the relays to switch several times during power up of the computer. This could cause some undesirable effects I would think. The serial and Ethernet do not seem to be affected. And, what is the difference between the serial versions which use a USB connector anyways?

Phil, That is correct. The battery '+' and external supply '+' are connected together. The voltage at the battery's negative terminal is measured and subtracted from the voltage at the '+' side. So with no batteries installed, 0V would be read at the batt '-' side. And when no external supply is connected, BT and PS will also read the same. This is all related to how the battery and external supply are isolated from each other through the diode 'OR-ing' circuit that allows the higher voltage of the two to power the radio. 73, Rich AC7MA On 07/15/2013 09:33 PM, Phil Hystad wrote: On the KX3 VFO B Alternate Display you read Time, Power Supply Voltage, Battery Voltage, and so forth.

I never paid too much attention to this before and I have had batteries installed almost from the time I put the KX3 together so I have not noticed this before. So, can someone confirm that if no batteries are used that BT shows the same reading as PS?

Re: [Elecraft] OT: Aircraft radio FM
Yes I read all about RCA screwing Edwin Armstrong on wideband FM. David Sarnoff had connections with the FCC to eliminate the old FM band (pre war) and have the 88-108 region allotted which made all of Armstrong's equipment obsolete. Also RCA claims to have invented a new wideband FM system to work around Armstrong's patents. Armstrong's wife finally managed to finally win out over the manufacturer's and RCA in lawsuits long after Armstrong jumped out of a hotel window in disgust and near broke from legal costs. I remember FM heralded after the war but nothing ever overcoming the AM broadcasters until years later when all the principals were dead by then! A sad story of corporate greed and corruption.

[Elecraft] K3 transmitting in diversity overloads the sub-receiver
I'm using a K3 with a sub-receiver, a KPA500, KAT500, dipole and vertical antenna. I was noticing a clicking noise while transmitting in dual receive and thought it was an antenna switch protecting the sub-receiver. As most of you know (I didn't) this is just the sub-receiver overload protection getting too much RF from my transmission. It took a call to Elecraft's fantastic customer service for me to figure this out. This only occurs if I use the amp at 500 watts. Not with barefoot transmitting. I really like the diversity receive and would like to use it while using the amp. I know I could probably move the antennas further apart but that's not possible. Is there another way to fix this?

[Elecraft] OT: no CCRs and no HOA
I left all that behind in 1979 when I moved north. Better luck finding such property here in Alaska. I moved from LA to a town of 75 at the end of a 16-mile dead-end gravel road. I harvested 17,000 board feet of FREE timber for my self-built two-story log house (USFS land). Firewood was just go get it - no permits! Where I currently live, about 100 miles west of that little town, there is no city gov't, no building permits, no convenants, no zoning, nada! I put up my two 50-foot towers and a 16-foot dish, built a 12x40 foot shed, installed a six dog kennel for my sled dogs, and installed a back driveway without intervention by gov't. Not likely I will ever move back to America. Can't afford to. Got no state income or sales tax. No property tax for seniors. And the state gives both of us checks just to live here (Alaska Permanent Fund). A hot day is 70F! Never have to water the lawn.

Re: [Elecraft] Relay boards for remote control?
There are others. I use a SERDO8R purchased from EasyDAQ.com. It has an RS232 interface and eight DPDT relays on a PC104 stackable profile. Current price is $81, which I think is a bit much, but it is a well-constructed board and is supported by National Instruments LabVIEW drivers (which I why I have it). For $97 you can order it with eight programmable digital inputs or outputs that operate in parallel with the eight relays. I think Denkovi has a broader range of products with more interfaces and lower prices. If I needed another relay interface I would buy the Denkovi USB Eight Channel Relay Board ForAutomation, currently selling for $41, but I have no experience with them. 73 de AC8NS Hop - Original Message - From: Tom tom...@videotron.ca To: Elecraft elecraft@mailman.qth.net Sent: Tuesday, July 16, 2013 4:06 PM Subject: [Elecraft] Relay boards for remote control?
