[Elecraft] New K2 Owner
All, I just acquired a (new to me) K2/100. It is a phenomenal little radio. The manual is not the clearest I have seen, so I do have a few questions. 1) When I tune in a CW station and narrow the CW filter with XFIL switch, I need to re-tune the radio to recenter the signal. Is this an issue with the alignment, or are there other settings that may be in play ? 2) Memories. How does one toggle between the memories and the VFOs ? I would like to load the 60M frequencies in the memories and be able to toggle back to the VFOs for general operation. 3) VFO Mode track. When changing the VFO from A - B, the mode does not change. In other words, if I have CW mode on VFO A, and I swap to VFO B, the modes remains CW until I manually change it to SSB. If I change the VFO back to VFO A, the mode will stay SSB and does not return to CW as was first entered. Is this normal for this rig ? 4) I understand that there is a preferred replacement for the main tuning knob from Kenwood ? Can someone point me in the right direction ?

I have used it for a little bit on HF but it's mainly been on 6 2M here with fantastic results! I don't know if this is the right forum to ask, but has there been any consideration given to creating an internal 70cm band transverter ala K144XV? I know that the main focus of the radio is for HF operation (which it does admirably) but having experienced the internal 2M transverter performance I cant help but wonder if there has ever been an internal 70cm option floated. Whilst some of the good folk on this reflector may eschew the 'band in a box' idea, for someone like me who operates predominately portable it does indeed make sense to go down that route. The less external cables and things I have to go wrong or get lost / misplaced the better. :-) Thanks for your time, Jeff Cochrane VK4BOF Innisfail QLD Australia Elecraft K3 #4257 __ 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 - Web mail provided by NuNet, Inc.

[Elecraft] K2/100 RF Power Output Control (SSB)
All, Still new to the K2/100 (6k serial number). I have a question about the power output control in SSB mode. I was hoping to be able to vary the RF output from QRP all the way to the 100W level, however when I advance the RF Power knob past the 12W indicated on the display, I hear a relay click and the radio goes to the 100W+ output level. This causes the power supply (RS-20) to actually go out of regulation (more than 22A) on voice peaks. Is there an issue with the PO control, or does it behave differently with the 100W amp ? 73 and thanks in advance, Gene K1NR - Web mail provided by NuNet, Inc.

Re: [Elecraft] SO-239 Concerns -- Another Perspective
I have also been bitten by the non-captive center pin on Type N connectors. In my particular case, I had 100 feet of RG-213 runing outside from the shack to a roof mounted antenna. Type N connectors on both ends. Then came the cold weather. One day, no receive signal, and funky SWR. Hmmm. After a brief investigation, and a trip to the roof, it was determined that the non-captive center pin had been pulled out of its N connector and therefore, the mating N connector, by the apparent contraction of the coax copper center conductor in the cold weather. What a pain. Therefore, whenever I use Type N connectors for professional or amateur use, I specify captive center pins. Failing that, I use another type of connector. All usual disclaimers apply.

I have been bitten by the non-captive center pin migration problem (almost impossible to find) and won't use N connectors again for any non-UHF high power application. This migration if enough creates an open circuit. It is hard for me to tell the difference in captive pin and non captive pin N connectors. Also I prefer the larger center conductor surface area of the UHF center pin connectors. They are proven to have very little heat generation beyond UHF. 73 de Brian/K3KO For example, DX Engineering does not offer the RR-8 series switches with N connectors. Using UHF type connectors, this system of remote relays offers superior port-to-port isolation and power handling from 1.8 through 54 Mhz at low loss and low SWR. Only due to superior engineering is this series of Remote Switches usable at 144 Mhz with slightly elevated SWR and reasonable loss of only 0.25 dB. However, these units are not intended and cannot be used on UHF, so N connectors are intentionally not available. There is no question that the constant impedance characteristic of the N connector make it a superior choice for low loss VHF and UHF applications. However, it is a fact that on HF frequencies, very high power at high duty cycle modes will heat the small diameter center pin of the N connector. Heating can cause the center pin to migrate, ruining the impedance characteristics of the connector and, at continuous high power, potentially cause a short circuit. If this problem were to happen during testing or operations, one might mistake high SWR or high loss as a defective of the switch, rather than a problem with the connector. This cannot happen with PL-259 and SO-239 connectors that are properly installed. At low SWR they can handle several kilowatts of HF RF. This is not to say that you cannot use N connectors on HF. Rather, the question becomes What are the benefits derived versus the cost of changing to N connectors for HF, where constant impedance is unnecessary?. The answer This is not a concern if you already have N connectors, though. You may use adapters or short coaxial jumper assemblies with differing connectors at each end, as offered by DX Engineering, with custom lengths available by telephone. These would cause negligible losses on HF, and would allow you to experience the superior port-to-port isolation of a DX Engineering RR-8 series Remote Antenna Switch immediately.

Hallas wrote: I agree with most of what has been said in support of UHF connectors for HF and low VHF -- with two reservations. 1. Many SO-239s provided as part of radio equipment are not up to the quality of Amphenol units. In particular, the spring fingers of the socket for the male pin loosen over time to the point that the connection becomes less than solid. This is particularly a problem if the connector is used repeatedly. I usually replace with Amphenol units, if I can get to them. Another great option is the Oak Hills BNC kit, designed to fit the hole pattern of the SO-239. 2. The other potential problem with UHF connectors, in my opinion, is the integrity of the shield connectivity through the connected pair. If the backshell loosens, there is no longer a solid connection either at the toothed parallel portion, nor through the backshell. This can be an issue in mobile or other high vibration environments and has caught me many times. Note that a type N, C or BNC pair makes it's shield connection through the inner spring tension sleeve, maintaining contact almost until the pair separates. The backshell is just used for
[Elecraft] KAT-100 Calibration Question
All, I am in the midst of calibrating my KAT-100 antenna tuner.

Note, the antenna tuner was set up to antenna port 1 before I put it on to CAL. My question is: What should the K2 be indicating for SWR in this configuration ? When I press the TUNE button on the K2, the SWR is showing Hi SWR then 9.9:1. I was expecting a pass through to the dummy load with a 1:1.

Re: [Elecraft] FTDX5000 Design Flaw
The phase noise on the original Icom IC-751 (not the A versions) was so bad that it was banned from our multi-transmitter field day site. Seems it took out a number of bands when transmitting-. Gene K1NR On Sat, 20 Nov 2010 12:48:53 -0800 John, KI6WX ki...@pacbell.net wrote: The ARRL is aware of this issue. This problem was discussed in my 1988 articles on phase noise in QST (March April issues). The article notes that a high phase noise transmitter degrades the performance of a low phase noise receiver to that of the transmitter. This article started the ARRL making composite transmit noise measurements. A strong signal (S9+50dB) from a transmitter with broadband -130 dBc composite noise in a 500 Hz bandwidth reduces the receiver's blocking dynamic range to 103 dB. Most top notch receivers show a blocking dynamic range of around 140 dB. In this case, the dynamic range is reduced because the noise floor is increased. I don't think most hams are aware of the problem. If you have a nearby ham running high power and your receiver doesn't work well when they are transmitting, you just assume that the signal is too strong for your receiver. This problem is like splatter or key clicks. It doesn't impact the owner of the transmitter, but instead degrades the receiving environment of those who live near them. There is little incentive for the owner of the high composite noise transmitter to improve their equipment. -John KI6WX The FTDX500 wouldn't be the only one, if a -130 dBc composite noise number defines failure. If you have access to QST reviews, compare: Flex 5000 FT-2000 Orion II IC-7700 K3 all of which plot tx composite noise at 100 or 200 W out to 1 Mhz. You can draw your own conclusions, but the FTDX5000 apparently isn't exceptional in that regard. The Flex is no better than -120 dBc out to 1 MHz, the FT-2000 is slightly worse than the FTDX-5000, and the Orion II is no better than -130 dBc out to 100 kHz. The Icom rigs seem to do a little better. The K3 performance indeed far surpasses the others. I could find no comment on these numbers in the reviews. Bob NW8L Why is this not sent to the Editor and Technical Editor or QST as well as the lead test engineer at the ARRL lab? What was their response?

When is the stock offering - so I can buy some Elecraft Shares? [I've been selling Elecraft radios for free and I'd like to cash in, to get paid for it. Owning the stock would do the trick. Please? ] Eric Manning VA7DZ Eric Swartz said: We are well past working from our basements.:-) A few data points: 1. Since shipping our first K2 from Aptos in January of 1999, Elecraft has grown into a healthy multi-million dollar high-tech company with a broad product line. We have -zero- debt, own all of our inventory, and have a healthy, and very stable, balance sheet. We build our products here in California, just outside of Silicon Valley. We are structured to be here for a long time, and certainly longer than most hams keep a particular rig. We want Elecraft to outlast both of us. 3. How did we do that? Elecraft designs great, high value, products that are fun to use. And our products, like the K3, continue to improve and get new features even -after- you buy them. We run a stable and tight financial ship - carefully trading off an internally financed growth rate versus risk and cash needs. We work hard. We hire great people who continually amaze us with their intelligence, creativity and work ethic. Our customer support team is one of the best. And we enjoy our work. 4. We also carefully listen to, and interact with, our customers daily. We are focused on being the most responsive, and fun, ham radio company to buy from - period. 5. Wayne and I are both healthy guys - a very long way from retirement. We are having a great time bulding and running Elecraft, and plan to do so for some time. But we are not the only people who continue to make Elecraft successful. 6. Our well staffed engineering design team is diverse and strong. I'd wager that it is as large as, or larger, than many HF rig design teams at our competitors. We are well past two guys doing all of the design in our basement labs. Our engineering, support, manufacturing and management people are top notch, with a lot of depth. We have a great team and plan to keep building it for the long haul. 7. We haven't been a 'QRP Only Company' for some time. Yes, in 1999 we first targeted at the QRP market since it was tightly focused, easily marketed to, and was our fastest path to a first product. Its still a great market, too. But we always planned to also offer 100W high-performance rigs, both kit and factory assembled, to compete against the best HF rigs from other QRO manufacturers. That's the major part of the market. I think you can agree we have more than succeeded in that area with the K2 and now the K3. The majority of our rigs go out the door at 100W. We are continually designing a diverse product line, ranging from QRP to QRO. The KPA500, now going into field test, is definitely -not- QRP;-) But stay tuned for more QRP offerings too! 9. Most important, we have incredibly enthusiastic and supportive customers. You make it fun for us! By telling your friends about Elecraft, the K3, and our other products, you keep us in business every day. You are our best salespeople. The more you enthusiastically tell your friends about our products, in person and on the air, the more new products we can design and sell. In today's economic environment, more than ever, this is incredibly important to us. Please - keep up the great work.

Re: [Elecraft] K2 Why MH2 mic seems dead
Electret Condenser mic elements are typically very sensitive to their mounting location. A small movement the element can make a huge difference in the sound. You may get better performance if you move the element to the front of the foam directly to the rear of the mic screen... 73 Gene K1NR On Fri, 28 Jun 2013 12:22:24 -0700 (PDT) k7nhb desig...@quickdata.com wrote: I've been reading posts about the MH2 mic and have had my own struggles with it. Is it common knowledge that the mic pickup element is only effective when talking into the top scree on the mic? If I talk into the front screen with SSBA at 1, it doesn't pick up a think. When I set SSBA to 2 or 3 is does pick up audio but I think that's because it is so sensitive it is also picking it up from the top. When I opened the mic, I saw the mic element in foam, in a compartment below the top screen and practically isolated from the screen if front of the mic. In fact, that front screen looked like it was just a plastic facade. Is that how mics are suppose to be made? My only guess is, by putting the capture area on top, it avoids speaking directly into the mic if you are expecting it to pick up via the front screen. I have that 600 ohm dynamic Kenwood mic that is often used with the SGC-2020 (up/down buttons on top). I thought about replacing the MH2 with it - mainly because its slimmer profile would allow it to fit in the Pelican case with the K2. Can someone tell me it that Kenwood would be a direct replacement or would I have to rewire something. It doesn't have a model number on it but I think it is MC-43s. What about audio quality - the K2 is only the QRP-ish model.

[Elecraft] [K2 ] RF Out/DC power Issues
All, My K2/100 (s/n 6k) has an issue with RF output control vs DC input power. When operating in the range of 1 - 10 watts (lo power), I draw what seems to be a reasonable amount of DC power, and the tune control works as it should, reducing the output power to approx 2W while the KPA-100 does its thing. Once I set the radio to 11 watts or above (hi-power), all bets are off. I am drawing approximately 15 A for 11 watts out pulling over 24A at 30W, and the tune function no longer reduces the output power while tuning. If set to 20W out, the tune function indicates no reduction in and will tune at 20W. The same for any other power range. My question is, besides D-16 and D-17, where else should I be looking for issues? Note, I do get an occasional Hi Current warning while operation in the 1 - 10 watt range.

Re: [Elecraft] marine frequencies and k3
George, The ** best ** solution would be for her to get her ham license. In that manner, she would be able to work the 14300 Maritime Mobile Service Net as well as a number of other maritime nets throughout the world. It will also give her access to other hams throughout the world. This could save her life. There are a number of weekend license courses that could help her along the way. I am sure that he HF radio and antenna coupler on her boat will cover the complete 3 - 22 MHz band and may go to 30 MHz. It may have to be keyboard/reset enabled. That would give her easy operation. Also, please DO NOT suggest that she use a ham rig for her primary marine HF radio. Most ham rigs are not set up for the rigors of marine operation and with the salt air and moisture, corrode very easliy. Marine HF radio have the commericial frequencies with correct T/R split already in NV memories. This is especially important for distress frequencies. These are normally a 1 button push. No it is not legal for you to communicate with her via HF on the marine band with out getting a commercial station license for you, and having a commercially certified radio at your station. 73 K1NR On Tue, 22 Mar 2011 22:07:39 -0700 George A.

Most of those radios are also capable of operation on HAM frequencies. I was trying to figure out if it was possible to legally communicate with her using my K3 from home. Can the K3 be modified to permit transmission on marine bands? I want to emphasize that I am not looking for an opportunity to use the radio for any illegal purpose. I am only interested in operating on marine frequencies for which I would have a valid license. Beyond this, it seems there is a potential marketing opportunity for Elecraft in the marine community. Ocean sailors use SSB and many of them also end up getting a HAM license so they can also use HAM frequencies on voyages. The Elecraft K2 and K3 are in some ways ideal for marine use because they are small and have relatively low power consumption. The stresses on a marine radio are huge and most of them have been made water and shock resistant. Also, marine radios require extreme simplicity of operation because they occasionally have to be used by an inexperienced operator during an emergency. Maybe none of this makes practical sense.

Re: [Elecraft] [K2] Hardened K2 for HFPack?
Actually, I was hoping that something like that would be the next Elecraft product. Maybe a K2-field, or a K2-A; a ruggedized, updated, version with lessons learned from the K3. Perhaps in a SG-2020 like package, with 20W and a antenna tuner mounted on the top with both a front and rear RF connector to allow use of the radio with a whip antenna in a pack. Use the external KPA-100 with KAT-100 for non-portable operation. Battery could mount inside the radio or on the bottom.

It seems to me you could produce side panels for the K2 that were longer in front and back to protect the controls in front and connectors in the back.These same side panels could have attached metal strap loops for carrying the K2 with a shoulder strap, and strap loops for tieing it down to an ALICE frame, etc., Perhaps the top and bottom could be extended too, at least in front, creating a box around the controls for protection.

Re: [Elecraft] K-3 Noise Reduction
All, For basic noise reduction operation, the ADSP-2 unit in the venerable SGC SG-2020 is about the best DSP I have heard. IMHO it sets the bar for all DSP NR units. The NR has 2 levels. The first level is excellent for electrical noise and QRN removal along with a great auto-notch function to remove tones, all without fatiguing digital artifacts. The second level is a deeper version of the first and can be used during strong signal high QRN/noise situations. The NR chip and algorithm are now quite old in electronics terms, but the technology is still valid and offers a great launching point upon which to improve. 73, Gene K1NR On Mon, 16 May 2011 22:24:04 +0200 Ruben Navarro Huedo runa...@gmail.com wrote: Yes, i think the same.

Re: [Elecraft] KX3 vs. K3 and other rigs?
All, The improvement in communications effectiveness of 20 watts verses 10 watts is valid - much more than the 3 dB increase in power would seem to suggest. I have seen the same results as with my SG-2020 as was mentioned below. Part of the effectiveness of that particular radio is the VOGAD speech processor as well. A similar algorithm for the KX3 speech process might be something to consider later. A small 30W PA with antenna tuner that would mount to the back of the KX3 would be simply amazing. Include a larger rechargeable battery pack and it probably couldn't get much better - IMHO 73 Gene K1NR K2 6Kxx On Mon, 6 Jun 2011 08:26:14 -0700 Wayne Burdick n...@elecraft.com wrote: We could offer a KXPA30 amplifier to deal with the need for more power in a much smaller size.

However from a communications effectiveness point of 20 watts is a much more realistic power level, especially for SSB QSO's. Most of the Mil Manpacks use this output power level.

I also have a SGC2020. 95% of the time on the first call I can get through and have the standard cookie cutter qso's and move on. If you try and do the same with 10 watts its very frustrating and much more of a struggle. These are NA Q's not local stuff. 5 to 10 watts is good power level for CW. For SSB 20 watts is far more effective, even with simple whips. Everyone will say its only 3db, however that 3db makes a huge difference when using simple antennas especially on SSB. While the AMP might be the answer, looking at the projected images and size, it will be a huge hassle carrying another box around. If you consider the size of Yaesu FT857, which runs a full 100 watts of output and its design is very neatly integrated into a tiny package, the KX3 with an external amplifier will be awkward by comparison. A FT857 with some AA batteries was carried to the top of Mount Kilimanjaro by HB9BXE. The operator successfully had many qso at 20 watts of output. He probably would not have packed a KX3 and amplifier if it was available then. I dont see why a duplicate of the KX3's PA could mot be offered as a piggy back box with another set of 8 batteries. I would rather follow that option than the 100 watt linear option. It certainly would be a lot smaller and portable than the 100 watt PA. I am sure many homebrewers will explore this option. Anyway time will tell. There is always the hombrew/modification option. The KX3 has a lot of potential and the design is 98% there. 73 John --- On Mon, 6/6/11, Dave KQ3T k...@comcast.net wrote: From: Dave KQ3T k...@comcast.net Subject: Re: [Elecraft] KX3 vs. K3 and other rigs?

Increasing the output power to 20 or 30 watts would have an impact on either the weight of the KX3 (more batteries needed to maintain a desired battery life) or the battery life (the existing batteries would not last as long at the higher power level). 2.

A rig designed for portable operation generally uses poor antennas and is optimized for weight, size and battery life. While its nice having great receiver specifications, you do have to be realistic about the real world requirements that is placed on the receiver when operating portable. For me battery life, convenience and power output are very important requirements rather than world beating receiver specifications. I would gladly have 30 watts output over ultimate receiver performance. Most military manpacks run 20 to 30 watts for good reasons. 10 watts and a wire in the tree type of operation does not demand a receiver with 100db of IMD dynamic range. If the KX3 does deliver incredible receiver performance for a bargain price I wont say NO, however I can live with lesser receiver performance when operating with marginal antennas. What I would prefer to see is an antenna tuner that will tune a 9 to 13 ft whip on all bands, or alternatively a end fed wire on all bands. A low noise figure receiver is important when using short portable antennas. We all waiting for the KX3 tech specs with baited breath. Time will tell whether we will get a

The MH3 has a matching plug. However, the mic jack can also be used with mics having a 3-circuit (stereo) plug. These will not provide PTT or UP/DN controls, but can still be used with VOX or the XMIT switch (equivalent to PTT). Two menu entries are provided for mic configuration: one to turn bias on/ off and another to turn the UP/DN buttons on/off. Heil headsets with two stereo plugs (one for stereo receive audio, the other for the mic) can be used. Generic computer headsets with these two plugs will also work. There are very small, pivoting mics available from places like Fry's that have a 3-circuit plug.

I just found the source of a loud noise which appeared to be emanating from a neighbor's house. The noise source turned out to be an electric blanket with independent control boxes and control units (rotary controls). Each box was causing either a loud click every second or a loud AC buzz when the electric blanket's control was set to call for more heat. I took a portable Sony AM/FM/SW radio with me to the neighbor's house and walked around the inside the house with him. At the far end of the house the signal was moderately loud with the antenna collapsed while listening on 10 Meters. When we got to the master bedroom, the signal got noticeably louder. Unplugging the AC from one box stopped one of the clicks/buzzes. Unplugging the second box produced silence. In the bedroom, the noises could also be heard on broadcast band frequencies, but were not very strongly in the AM BC band outside the house. The frequencies with the strongest signal from a noise source is often related to the length of the wires attached to it. In this case, the signals seemed to peak on higher frequencies in the 6M and 10M bands. In the case of a noisy power line, where the wires are attached to arcing hardware are physically longer, you can expect to have stronger signals on the lower frequencies. But even with power lines, in addition to using an AM BC radio, it is often helpful to use a portable radio that can tune in the 108-130 MHz AM aircraft band to find noise sources on power line poles. In your case, if you can hear the noise on a portable AM radio at the breaker panel, try killing power to one breaker at a time to see which one kills the noise.

Re: [Elecraft] Power Cord Questions
Lee, What size wire are you using ? Should not be smaller than #12. The length should be as short as comfortably possible. That means as short as possible with enough extra length to dress the cable around the operation bench if/as needed, and to be able to pull the radio out of its operation position easily with out pulling the power cord out of the radio either on purpose or by accident. No need for any more length. Also, Be sure that the connections at the power supply terminals are solid. I used to work summers at a power supply house. They made very high current regulated power supplies for the military. There were instances where the customer would connect the test load to the PS with clip leads, and when the voltage at the load was out of spec, send it back. There was nothing wrong with the supply. The clip leads had too much resistance, and at the rated load, would drop too much voltage because of the bad connection at the PS terminals. Be sure your connections to the PS are clean and tight. Fuses should be mounted close to the supply, just like they are in your house. In the event of a short, you want to break the circuit before a fire starts. Present (currant?) thought says to fuse both leads. Use low loss auto blade type fuses. Other fuse holders can have a lot of resistance, and under load, drop the voltage. I have seen the cheap clip type de-solder a fuse cap ! You can get the auto blade holders with red and black leads at your local auto parts store to build your own, or buy them from Quicksilver Radio http://qsradio.com/index.htm or Powewerx all made up. http://www.powerwerx.com/fuses-circuit-protection/atc-inline-fuse-holder-ring-terminals-10-gauge.html 73, Gene K1NR On Fri, 9 Mar 2012 18:37:44 -0800 (PST) Lee Buller k...@swbell.net wrote: I am rebuilding the power cord from my RM35M to the K3.

Those who receive the first batch of KX3s should be aware of a few things: - Some firmware features are still being added or improved, and we could be releasing new beta code as often as every few days. You can load new code whenever you find it convenient. - There are some last-minute hardware items that will be shipped after the radio itself. This includes the battery charger (probably a few weeks away). Any such items will be very easy to install. - The printed owner's manual will initially be at revision A3. The electronic version of the manual will be updated much more often, including the errata sheet. Of course the electronic version is also searchable. - Because of last-minute changes, the first edition of the kit assembly manual is probably out another week. We have to test the assembly and configuration procedures to make sure everything is working. No doubt we've overlooked a few things in firmware or documentation. We'll answer any questions as quickly as possible. But we're very much looking forward to getting your KX3s shipped! 73, Wayne N6KR __ 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 - Web mail provided by NuNet, Inc.

Re: [Elecraft] K3 or KX3 on my sailing yacht?
All, IMHO, no amateur series transceiver should ever be used as a safety-of-life marine transceiver. Only marine style radios should be used for same. The main reason is the highly corrosive environment in which the radio lives. Most amateur radio sets are not sealed in the same way that a true marine radio is. Continued exposure to salt air/moisture can rapidly corrode a radio leaving it useless when it is most needed. Other items in favor of a pure marine transceiver are the built-it ITU channelization, and single button distress system - Digital Selective Calling (DSC). DSC has the ability to be connected to the ship's GPS and to auto-broadcast the ships name and position with the push of a single button. Depending upon the system, the DSC may be able to broadcast the type of emergency as well. Lastly, many of the marine HF radios can be opened to allow operation on the ham bands allowing check in on the Maritime Mobile Net and others. Once again IMHO. YMMV 73 Gene K1NR along with the marine channelization and - Web mail provided by NuNet, Inc.

Mike, Park your radio on 50.125 don't JUST listen, CALL CQ occasionally! Make some noise. If everyone listens and no one calls, no one will know that the band is open. By calling, you may even run in to a few locals as well. Also, remember the AM crowd. They are frequently on 50.400. Listen there as well. There is an activity day time of Saturday morning at 6AM.

Re: [Elecraft] K3 power supply recommendations
Another vote for the RM-35. I have had mine for over 30 years. Not an issue. Note however that Astron over specs their power supplies. They claim that the RS-35 will do 25A continuous. It will not. It gets too darn hot. Given the heatsink, it should do about 20 continuous. This is with static air cooling, no forced air. That being said, the RS-35 powered all 12 volt equipment in my shack including the 120W HF radio, TNC, 50W 2m radio for packet and dx cluster, and any othe vhf or other radios that I wanted on. I have seen the ammeter move past 33A when the SSB voice peaks combine with the transmit cycle of the packet radio, with no issues. 73 Gene K1NR K2, KX3 On Tue, 16 Apr 2013 21:05:18 -0700 (PDT) Wes Stewart n...@yahoo.com wrote: Use your meter.

[Elecraft] K2 and Remoterig
Wayne et al, Any testing on-going with Remoterig and the K2 ? Thanks, Gene K1NR On Wed, 21 Sep 2011 07:48:14 -0700 Wayne Burdick n...@elecraft.com wrote: David Windisch wrote: Can you say in advance whether the Remoterig twinning (no computer required at client or host site) concept will be supported by the K3? Yes. The next release of K3 firmware will allow you to connect two K3s together, with one acting as a terminal only, the other as the remote radio. You can do this either with the RemoteRig control boxes, which do not use a computer, or just with a null modem cable going from one K3's RS232 jack to the other's. (A null modem cable can be made with as few as three wires.) The terminal K3 does not put out RF or audio -- that is handled cleanly over the network by the RemoteRig hardware. The terminal K3 just sends switch/knob/potentiometer events to the remote K3. This means it can be a completely stripped-down K3, like a K3/10 with no options. If remoting K3s turns out to be very popular, we may in the future offer a K3 that's front-panel-only to be used just as a controller. The KX3 could also, in theory, be used to control most K3 functions, although it has far fewer controls, so it wouldn't be a complete emulation. Virtually the entire K3 user interface is supported by the new remote- control protocol. It really feels like you're using the remote K3 itself, including a 100% accurate emulation of the remote K3's LCD (flashing icons, etc.). Over a long-distance network there might be noticeable latency in the use of some controls. But with a direct connection or a LAN, there's barely any lag. You can manually go in/out of terminal mode, or let the RemoteRig box do it for you. Additional details will be provided when the RemoteRig boxes become available. They're doing extensive testing. 73, Wayne N6KR __ 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 - Web mail provided by NuNet, Inc.

[Elecraft] [k2] Computer Control Issues
All, Trying to get my K2/100/KAT-100 operation with N1MM. Bought the Elecraft USB-Serial adapter. Installed the driver from the FTDI web site. Seems to be operational. Connected the cable to the computer (device found, etc). Connected the other end to the radio/antenna tuner cable, powered up the radio, and get the INFO 080 error. Also, and the antenna tuner will not power up.The serial cable is a Y configuration running from the radio to the tuner and then to the db-9 where the serial- usb converter is located. Turning off the radio and removing the cable returns the radio to normal ops. I disconnected the antenna tuner portion of the cable and still get the same error. Reconnect everything with out the serial-usb converter in the line and all works normally. This is not a stock serial cable. It is supposedly one made especially for this application i.e K2 special cable. I guess I will start by ohming out the cable. I need to find the correct schematic which is in one of the manuals I assume. Any other ideas would be appreciated. 73 Gene K1NR K2 6XXX - Web mail provided by NuNet, Inc.
