Re: [Elecraft] Wanted - EC2 enclosure
Hello again, Nick. I happen to have one in my "to sell" pile - bought it new and never used - literally not a mark on it. No KAT100 panels, just stock EC2. (I might have both sizes of tilt bails for it, I think 1.5" and 2.5"). $65 shipped On Sat, Sep 8, 2012 at 9:24 AM, Nick Marsh wrote: > Hello Folks, > > I am shopping for an EC2 enclosure, would be a plus if it had the KAT100 > panels.

[Elecraft] K3 - remote tuning knob

Re: [Elecraft] 472KHz/500KHz
There is another caveat to keep in mind when using the K3 in transverter mode. Sensitivity will be subject to the ham band BPFs, so a preamp may be needed if the "IF" freq. falls well outside the BPF passband unless a general coverage module (KBPF3) is installed. The KBPF3 works fine if the KXV3 is in TEST mode but the K3 is not setup with a transverter band, ie. you're parked on 10.500 MHz for 500 kHz conversion. However, when using a transverter band (ie. direct freq. readout using IF=10, RF=0), the KBPF3 is not switched in when it should be. I have brought this to the attention of support/development since it is clearly a bug and there should be no need for a preamp with the KBPF3 installed. In the meantime, I use IF=14 and RF=0 for a transverter band and get direct freq. readout. The 20M ham BPF is wide enough that there isn't a significant amount of attenuation at 14.500 MHz. Having both 3.5 MHz and 10 MHz would be good additions to the transverter IF selections. The former because there are numerous converter circuits published or were/are commercially available based on 3.5 MHz, the latter because it is a defacto reference freq. 73 - Eric NO3M (WD2XSH/46 - ARRL 600M Experimental Group) -- Eric, Thanks for reminding that a KBPF3 is needed for general frequency use in TEST mode. I chose to install one when I bought my K3/10 because I was going to operate on 500-KHz with my K3. It is not operating in transverter mode but in TEST mode as RF output is at the transverter output RF jack and not at ANT. So there is no need to use transverter mode. Frequency would read 10.472 when on 472-KHz. I think that much easier than having to build a stable xtal LO on either 3.5 or 7.0 MHz. I bought my OCXO on e-bay for $42 and drifts about 1-Hz every 4-6 months. But that is just my opinion. 73, Ed My prototype transverter uses a SBL-1 mixer from mini-circuits and a 2N3906 buffer amp into a three-pole filter. That has enough RF to drive my 500-KHz linear amp. Others will need to come up with linear's to provide at least 25w to take advantage of the expected 1 ERP limitation on 630m. With my antenna efficiency 100w => 4.15w ERP on 500-KHz. __ 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] Portable antennas for use in UK
Just returned from another two weeks in the UK, this time bringing my KX3. My wife and I visit her mother in the Borders area of southeastern Scotland four (+/-) times a year. I duplicated Wayne Burdick's kit as closely as possible, but it's really a nice weather sort of system and, frankly, I've found there isn't a whole heck of a lot of that in Scotland. I use a TransWorld antenna here with very good results, and I hear good things about the Buddipole. I'd like to use something like that over there and just keep it at my mother-in-law's place so I don't incur extra baggage charges and stress about lost luggage. Given shipping and potential duty costs, I'm wondering if there is something portable like the TransWorld or Buddipole that's made in the UK or perhaps elsewhere in Europe that I could acquire and store there between trips. Can anyone make any suggestions? I'm operating mostly 20 and 17 meters these days, but also interested in 30 and 40 meters. By the say, I had no hassles with security with the KX3 either in leaving the U.S. at Dulles Airport, or in Paris during two transfers, or in Edinburgh. I did carry my original license and printouts of CEPT operations in both English and French in the carrying case, but no one asked to see them. 73, Dennis, N7DH/4 Hillsboro, Virginia __ 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] K3 and AL-811 amplifier interfacing...
The AL-811 manual states that "Relay: keys amplifier when grounded. Sources +12 VDC open circuit and supplies 100mA when grounded. A built-in pulse canceling diode protects the exciter. " Several years ago the question of how much voltage and current does an Ameritron put in its key line. I measured mine which was configured for 220V (I no longer have that amp). I came out with around 14 or more volts and at least 100 mA, maybe higher. Looking at the schematic there was no regulation on that circuit, it came straight from the transformer. Since mine had more juice going in, it surmised that more was coming out. So be careful if you connect a rig with a keying line that is not as robust as a K3's.

[Elecraft] [K3] K144XV Reference Lock Board
While cobbling an order together, I found "K144XV Reference Lock Board" marked as new on the order sheet. I tried to find more information about it on the K3 web page and on the K144XV pages, but didn't find anything. Questions: How does it interact with the KTCXO3-1 TCXO (0.5 ppm typ) High Stability Ref. Osc. option? Is the high stability option recommended for use with the reference lock board? What effects to people see on SSB and CW with the reference lock board? For the moment, these questions are academic, since my Mac-only shack can't reload the firmware on the K144XV and that is required as part of the install (according to the install manual).

Re: [Elecraft] K144XV ordering
The K144RFLK is strongly recommended. There were frequency stability issues with the 116 and 118 MHz crystals (though believe this was improved sometime in the last year or so) used for the injection frequency at the tranverter. The K144RFLK removes that problem, because the root frequency reference will be the TCXO in the K3 (or the K3EXREF source if you have a 10 MHz lab reference avaiable). 73, matt W6NIA On Sat, 08 Sep 2012 16:42:54 -0500, you wrote: >To: elecraft@mailman.qth.net >Subject: [Elecraft] K144XV ordering >From: SRD >Date: Sat, 08 Sep 2012 16:42:54 -0500 > >Hi, > >I'd like to make sure I've got this complete (always did hate the >order page).

[Elecraft] Antenna static charge precautions - any tips?
Hello Group, I've just re-hung my 80m horizontal loop. With so much wire in the air, I'm reviewing my static charge risks and how to reduce them to protect my K3. I'm in the mountains - things get bumpy and charged up here. I once lost the wattmeter diodes in my K2/100 to a static event, so I'm looking for prevention. Any advice will be gratefully received. Here's my new setup: 80m loop fed with open wire line to a DX Engineering 1:1 balun outside the shack. A 5 foot length of RG213 brings the signal from the balun, through the shack wall to an AlphaDelta antenna switch. The outer shield of the RG213 is connected to the station ground, at the balun, outside the shack. The AlphaDelta switch is connected also to the same station ground. It grounds the centre conductor of all antenna lines when in the "common" position - and I leave it this way whenever I'm not operating. My understanding is that any antenna lines are protected by a gas discharge capsule in this switch, which acts as a "fuse" in the event of significant static discharge on an ungrounded line? "Station ground" here means 2 copper pipes buried in earth outside the shack and connected by about 6 feet of cable. One of the pipes is in very damp earth most of the year, the other is sheltered and is in dry soil. Is this setup sufficient to manage static discharge risk from my antenna, or are there other precautions I should be taking? I've read about ICE static discharge devices and high value resistors from both sides of the ladder line to ground. Just looking to minimise risk without going overboard.

Re: [Elecraft] SSTV Reception on the K3
Mark, HRD/DM780 will try to set your K3 to SSB, but if you can override that and select DATA A instead, there will be fewer problems - for one thing, K3 DATA modes automatically set TX EQ and RX EQ to flat and set the compression to zero. so you don't have to invent macros to turn those things off. I admit, the last version of HRD that I have used is the 5.0 beta from before Simon sold it. There may have been changes beyond that point that I am not aware of. I don't know the future of HRD other than I understand it will become a "for pay" application. While that is not bad, it makes me investigate other applications for my purposes. I have been experimenting with Fldigi which seems to fill my needs at the moment. I do not desire complete rig control, only that associated with digital modes.

Re: [Elecraft] Antenna static charge precautions - any tips?
John, Put a resistor across each feedline is my advice. A value from 22k (I like 3 watts for legal limit rating) to 100k will discharge the static. A DC path across the feedline is a very good protection against antenna static damage to your rig - the path to ground is not as essential as across the feedline, but a path to ground does add benefit as well. You can add resistors at the feedpoint of your antennas - that gives an added benefit of being able to check for breaks in the feedline, just measure the resistance across the feedline. That does not work for loops since the closed loop should indicate a resistance that is quite low itself. If you care to open the Alpha Delta switch, that is a great place to install them - if you have no other choice, put the resistors in a PL-259 body, one lead to the center conductor and solder the other lead to the shell - then use a Tee adapter to connect the resistor across the feedline. The Gas discharge tubes are effective against large charges - the ones I have will squelch a voltage in excess of 600 volts, but below that level, they will do nothing. That 600 volt surge is enough to take out the diodes in the K2 KPA100. The K3 has more protection. but still should not be trusted when it comes to static charges. The simple resistor across each feedline will bleed off static and help substantially. An alternative to the resistor is a choke (of adequate current capacity for the power of your station). In a 50 ohm system, 100 uHy or greater will be good down to 160 meters. 73, Don W3FPR On 9/8/2012 8:25 PM, zen...@netspace.net.au wrote: > Hello Group, > > I've just re-hung my 80m horizontal loop.

Re: [Elecraft] Transverters?
Gil, The Elecraft XV series transverters were designed to interface with the K2, and then extended to the K3. If your K2 includes the K60XV option with its 1 mW TX and RX connections, the operation is seamless. The K60XV transceiver ports connect to the transverter and the HF antenna connections can stay in place. Without the K60XV, operation is still great, the transverter will accept up to an 8 watt input signal from the K2 high power output, but you will have to switch between the connection to the transverter and to the HF antenna. Once that hurdle is passed, the operation is again seamless. The K2 TRN menus allow you to set up the frequency display as you want it (including any offsets). 73, Don W3FPR On 9/8/2012 9:11 PM, Gil G. wrote: > Thanks Ray, > > I should have mentioned that I was considering a 2m Elecraft transverter for > my K2... > > Gil. > -- > PGP Key: http://keskydee.com/gil.asc > > On Sep 8, 2012, at 7:21 PM, Ray Sills wrote: > >> HI Gil: >> >> It depends on the transverter design.

Since the purpose is to bleed off static buildup, high resistance is fine. Depending on your antenna, frequency, feeder impedance, and feeder length, who knows what the impedance is at the shack. It could be above 2000 ohms in which case ten percent of your power would be dissipated in the resistor. Go high resistance and you won't have to worry.

Re: [Elecraft] KPA500 Question
Hi Jack... Thanks for the reply. Yes, RADIO has been set to BCD since I put the AMP online today. The band changes just fine under the control of the FT-950, so the amp is getting the correct info. I checked to make sure the amp changed with each band selected on the FT-950. It's just when I change bands, the amp will not go from OPER to STBY automatically with the BAND CHANGE parameter set to STBY. The amp is serial number 1041 and the firmware is 1.11 from August 21, 2012. It would be nice for the amp to go to STBY, so I can make sure the auto-tuner is good to go.

Re: [Elecraft] Antenna static charge precautions - any tips?
OK a bit of explanation is in order. The K2 (and K3 as well as the K1) control power based on measuring the actual output power and adjusting the drive to provide the requested power level. That means a device capable of measuring the RF output is necessary. Well, that is the wattmeter in the KPA100 - it uses Schotky 1N5711 diodes because those have been chosen to provide the best response with respect to frequency and power level. Yes, those diodes are a bit "tender" with respect to static. Those diodes live right at the antenna terminals and are quite susceptible to static charges. The K2 (K3) power control system will give you the most consistent power control (because it is a closed loop), but to operate, it must be able to measure the output power. and the diodes that do that task are susceptible to static discharges. Yes, go out and find yourself some resistors between 22k and 100k and connect them across your feedlines. Note that I do not care about the path to (earth) ground - while that may be nice, IMHO it will not help with the equipment damage from antenna induced static charges. Yes, the station should be connected to earth ground, but for purposes of lightning protection rather than static discharges from antennas. There are 3 grounds in a ham station - AC safety ground (see NEC requirements), Lightning safety grounding (see Ron Block's papers at Polyphaser,.com) and RF ground. The RF ground is the most elusive, because it does not include any hard connection to mother earth. "Ground" in this sense is a point of commonality, or a point where the RF voltage is zero. That condition occurs at the feedpoint of a balanced antenna - the zero voltage point directly between the feedpoint terminals. OK, I am mixing a bit of the theoretical and the practical, but take to heart, it is not hard. When the wavefront moves from the feedline into the antenna, the conditions change from conduction (obeying Kirchoff's laws) to radiation (obeying Maxwell's wave equations). Where the transition point occurs is indeed a mystery. That has nothing to do with the "ground question".. Everything needs to have a return path, and I believe that is valid for RF as well as for DC conditions. This is the Kirchoff stance,, but there are those who argue than the Maxwellian equations offer a better explanation. That may be true, but there is little difference. My goal is not to "solve" this inconsistency, but just to add a bit more information (OK, to justify my conclusions be they right or wrong). 73, Don W3FPR On 9/8/2012 10:07 PM, stan levandowski wrote: > Thanks, Don.

Re: [Elecraft] Antenna static charge precautions - any tips?
Don is totally right. But, cutting to the chase, put a 100K resistor across your coax before it gets to the receiver. Easy, no RX mods, just put a 100K resistor ... 1/2W will do fine ... into a PL259. Put a UHF T-connector on your radio, put the antenna on one leg, put your resistive PL259 on the other. Trust me, you *CAN* fry the input stages to your radio and it won't even look like you're doing it as you are. Been there -- done that, more than once, we all learn slowly. :-) No bleed = charge builds up in the input capacitance, it will eventually take something out. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org On 9/8/2012 8:03 PM, Don Wilhelm wrote: > OK a bit of explanation is in order.
