[Elecraft] K-2 Alignment Test, part 1 question
I have completed all items of Alignment and Test, Part 1 with one exception - Setting the AGC Threshold. Instead of the expected 3.8 volts on pin 5 of U2, I could only get 3.6 volts. The adjustment range of trimmer R1 was 2.5v to 3.6 v. The 5 volt regulator output is 4.9v. RF gain control was fully clockwise as called for in the manual. Any ideas on why it would only go to 3.6 volts and is this critical? I left it at 3.6v and proceeded with the remaining alignment and test (part 1) procedure without incident. Another observation was that the 8 volt regulator was a bit low at 7.6v. The voltage and current as measured with the K-2 metering circuits were 13.6v and 80 ma. An external current meter should about 100 ma. Any help will be much appreciated. Larry N4QY___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] KX1 help
Howdy, I am new to amateur radio and just upgraded to General a few months ago and have some basic questions on a power supply for the KX1 and how to make a wire antenna. I am going to add the auto tuner and the optional 80 and 30 meter board later. So as far as a power supply can I use an old AC adapter as long as it is within 8 to 14 VDC and if so how should it be connected to the connector for J1. Or would a commercial type application be a better choice. As far as the antenna is concerned what type of wire should be used and how is connected to the connector. I hope that as I start building my kit that these answers will be a little more obvious but I am trying to get as much information as I can before I start building.

[Elecraft] Reply to RU Comments by K6LL
Dave, I saw the same thing with the bandpass tuning, but did not know what I was really looking at. I thought the adjustment to 300 Hz was rather course and using shift was also course. I have a 500 Hz filter which did OK. But, it was hard to deal with the width/shift issue because of the lack of a fine mode. That is a brilliant idea if they can do it. I just lived with it, but the K3 is so good at 500 Hz filter I had very little issues receiving...except for those guys ( and I must have been one too) that would crowd you. I think there should be a fine mode for both width and shift. As far as the amp is concerned...I have an AL82...and I saw nothing like that, but I do not have the meter you might have. I just noticed a power drop of 200 watt or so when I was using the dual PB feature. I left it off for most of the contest. I also saw a drop in signal strength when I turned it on. Other than that, the AL82 is not all the sophisticated about the spike issue...at least on my metering I could not see anything.

Re: [Elecraft] K2 filter center frequency shift with band?
Julian, Don: You hit it right on the head - I'd forgotten about the sideband reversal issue. Hitting CW RV puts the audio signal right where I expect it when using 15m. I was shifting the MARK frequency by about 900 Hz (using the values built into MMTTY, from 1175 to 2000) which was a little bit too far. If I do a lot of RTTY (unlikely), I may revisit how the filters are set up and try to get them symmetric; I don't recall being very careful in the setup with I first tried to get RTTY going.

Re: [Elecraft] K3: Still unable to set power correctly in, DATA A(sigh)
If the onboard meter _thought_ the K3 was making the requested power, that would be one thing. But in this case the onboard meter thinks it's putting out 2x the power, which it is. It depends on what part of the system thinks what. In this case the MCU is reading a given value but interpreting it as something else thanks to TXG VCE. TXG VCE does not effect the peak power in SSB or AFSK A with single tone modulation. It does effect peak power in DATA A. If you are seeing about 2x the power called for, decrease TXG VCE by 3 dB and see if the situation does not resolve itself (at the expense of power output in USB/LSB). Although the wattmeter is peak reading according to Wayne, TXG VCE still provides an inappropriate adjustment. 73, ...

Not true ... in spite of careful calibration at both 5 and 50 watt levels neither of my K3s has ever produced exactly the power requested on any band other than 20 meters, on any mode other than CW and at any power other than 5 or 50 watts. The variations can be as much as 3 dB on SSB depending on the peak to average ratio of the driving audio and amount of compression used. Setting a power control calibrated for CW and expecting that level to be accurate for PSK31 or any other arbitrary digital modulation is complete folly and utter hubris. Among other issues the wattmeter does not know if you are setting peak or average power and it does not know what the average power should be for the arbitrary data and arbitrary modulation. For the K3 to accurately control the power level in all modes the its directional coupler would probably need to be improved by at least an order or magnitude. The response flatness would need to be improved by at least an octave and the detectors would need to be substantially more linear ... and that's just for CW. To handle arbitrary audio inputs takes some knowledge of the peak to average ratio as well as the peak duration (duty cycle) in order to select the proper detector time constants. Every voice every digital mode and every arbitrary data stream will have different peak to average ratios and duty cycles. Do you expect the DSP to calculate those values on the fly? Perhaps the power metering should be derived from a DSP based spectrum analyzer? Accept the fact that the power level control is relative. If Wayne and Lyle can improve on it that's great. However, trying to hold .1 dB or even 1 dB accuracy from 1 mW to 120 W, 1.8 MHz to 54 MHz with arbitrary modulation sources in a reasonably priced amateur transceiver is a fool's errand. 73, ...

[Elecraft] K3: The ARRL RTTY Round UP
I only have had a handful of RTTY contacts since getting my K3/10 (# 0430). Did play in the RTTY Round Up for a few hours. Cranked it down to 1 watt (I don't know why I keep doing that!) and worked 74 Qs and 31 Mults. Even worked Lee in KS (who bagged over 1K Qs! ) Like Dave, I programmed two CW memories (no [external] computer) and let her rip for search and pounce. Even worked LU, JA, XE, P4 plus several states. That was fun! Antenna, by the way, was my lame 88' dipole with one leg kind of vertical and fed with 450 ohm ladder-line. Did notice, espcially on 40m yesterday afternoon, that there were solid RTTY sigs from 7.000 - 7.100 MHz. Guess it's the WARC bands if you're looking for a CW ragchew. I do hear some of the digital guys complaining about CW contests on different weekends though so I guess we get to trade a bit. 72, Tim K5OI Ruidoso, NM ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3: The ARRL RTTY Round UP
Changing SHIFT and WIDTH granularity to 10 Hz from 50 would improve CW useability as well. A lot of us have formed contest operating habits and tactics based on analog SHIFT and WIDTH functions. Like a combination of a small shift and (sometimes) a lesser width change to put someone up or down just a bit farther down the passband and keep the same skirt frequency on the opposite side of the passband. 73, Guy wayne burdick wrote: All RTTY issues noted, Dave -- thanks.

Ed, First welcome to a great hobby. I would advise against using that 'old AC adapter' - those wall warts are usually not regulated and the no-load voltage often soars to 1.5 times the voltage shown on it, and at high current loads, the voltage sags a lot. For home station use, you will likely accumulate several things that run on a 12 volt power source - that is actually a 13.8 volt power source, the voltage of a fully charged lead-acid '12 volt' battery like that found in an automobile. So my recommendation is that you get a regulated power supply that is rated for at least 3 amps (I would actually suggest one that is rated at 12 amps or more, you will eventually need it). Put a 2 amp fuse in the power cord to the KX1 to protect it near its maximum current draw plus some reserve. As for the antenna, there are several choices to make - what bands do you wish to use it on? Is this an antenna for portable use or will it be a permanent part of your home station? A half wavelength dipole fed with coax is the simplest antenna, but the coax fed dipole is a single band antenna. - there are ways of using it on multiple bands - traps, or extra half wavelength wires for the other bands spaced away from each other - use a 1:1 balun at the antenna feedpoint. Alternately, you can feed the dipole (single wire cut for the lowest band) with ladder line and use a balun in the shack to convert to an unbalanced line and connect it to the KX1 with a short length of coax. - you will need a BNC connector at the KX1 end. The KX1 autotuner does not have a lot of range on 80 meters, so get the antenna plus feedline as close to 50 ohms resistive on 80 meters as you can. If you use a 135 foot wire and feed it in the center with a length of 450 ohm ladder line that is 122 feet long (an electrical half wavelength), you will come pretty close to a 50 ohm load at the shack end of the feedline, and the tuner should handle it on the other bands. If you want additional information about antennas and transmission lines, I would refer you to the ARRL Handbook (every ham should have a copy). You may also find the Antennas, Transmission lines, and Tuners article on my website www.w3fpr.com informative. Yes, build your own antenna, it is a lot of fun to experiment with antennas, and it is much less expensive than the prices charged for pre-built antennas. Some even tout very impressive specs, but that is a stretch of someone's imagination, the basic laws of physics must apply, and some of the ads stretch that truth. (Rant off now!). 73, Don W3FPR Edward Doyle wrote: Howdy, I am new to amateur radio and just upgraded to General a few months ago and have some basic questions on a power supply for the KX1 and how to make a wire antenna. I am going to add the auto tuner and the optional 80 and 30 meter board later. So as far as a power supply can I use an old AC adapter as long as it is within 8 to 14 VDC and if so how should it be connected to the connector for J1. Or would a commercial type application be a better choice. As far as the antenna is concerned what type of wire should be used and how is connected to the connector. I hope that as I start building my kit that these answers will be a little more obvious but I am trying to get as much information as I can before I start building.

[Elecraft] K3: The ARRL RTTY Round UP
Ladies and Gents I just about cleared a thousand Qs this weekend in the RU in only 17 hours of on-the-air time. The K3 was spectacular in performance. The RX is magnificent and copied signals that I could not hear out of the speaker but printed on the screen. This happened many times. From Kansas, I did get to work some deep Europeans and even Israel called me. I did not hear any Russian stations at all. The DX was weak but workable. Magnificent RX. The TX was healthing and robust. I was running my amp so I was only running about 60 watts or less. The TX stayed cool and stable. The only issue I noticed was that between Dual PB on and off...the power would drop about 200 watts. No big deal, but interesting phenomonon. With the Dual PB on...the power would drop...with it off...the power would return to normal. Wayne and Eric already know about this issue. Thanks to all who worked me. Fun contest.

Re: [Elecraft] K3: The ARRL RTTY Round UP
Lee and All, I tinkered with the contest for a couple of hours too. I used a pretty spartan setup though--just the K3 with a couple of programmed memories--no computer. I set the power to about 60 watts, and was knocking them off pretty well too. I know I need to get set up a little more substantially for RTTY, but I was just playing around. Anyway, it was a hoot, and the K3 did great. The versatility of the K3 sure makes it a lot of fun to own.

Re: [Elecraft] KX1 help
Welcome to a very fine hobby Ed. As far as a power supply is concerned you didn't exactly specify what type of AC adapter you are planning on using, but if it is a wall wart, I would advise against it. Most of them have no voltage regulation and if the voltage swings high enough above 12 V you could damage your radio. Lack of recognition is also likely to result in chirp on your signal. I think a much better choice would be a small regulated power supply. I have an inexpensive one from RadioShack which I have had for years and has successfully powered a number of small items. An antenna is a simple thing to build and put up. I would suggest using something like 14 gauge copper coated wire. It's length can be determined by the formula 468/frequency, choosing a frequency somewhere in the middle of the CW band of interest. Once you have the overall length, simply cut the wire in two. You can use an insulator for the center of the antenna. Then attach the end of each dipole wire you just cut to each end of the insulator. Then solder the center conductor of your coax to one of those wires and the shield to the other wire. Solder the other end of the coax to a PL 259 plug and you should be done. After you have upon the antenna up in the air key up the rig and check the SWR if it is too high, that is above 2.0, choose a frequency near the bottom of the band and key the rig while looking at the SWR reading. Then move to the top of the CW band and key it again noting the reading. If the SWR reading is higher at the top of the band that was at the lower end, your dipole is too long. Trim off a few inches from both ends of the dipole, keeping the amount of trim the same, and take the reading again at a frequency in the middle of the CW band. If the SWR has improved you are on the right track. If it is at least below 1.5:1 you may wish to leave it at that. Achieving a 1.0:1 exact match is not all that important. However, if the SWR is still above 2.0:1 trim off a bit more from each end and see what happens. If the SWR reading at the bottom of the band is higher than the reading at the top of the band, your dipole is too short. If you wish to lower the SWR you will have to solder some wire of equal length to each end. That is not the best idea because you must be careful when attaching the lengths of wire to make a mechanically secure connection or the antenna is likely to come apart during the first windstorm. I forgot to mention that the ends of the dipole should be attached to insulators and then to a rope which you can use to secure the antenna to a convenient tree branch or other support. I suspect the foregoing was a lot more than you really wanted to hear, but I remember my first ham experiences when every bit of information I could get was helpful. You may wish to invest in an ARRL antenna book or handbook. Both have a wealth of information for the new ham as well as more experienced hands. Best of luck. I hope to hear you on the air soon.

If I set it to YES, then audio is output from the internal speaker and the headphone jack as expected. Why might the internal speaker be disconnected in normal operation?

Re: [Elecraft] Multi two with two K3's
It sounds like you are on the right track. You will need two band decoders to convert from Elecraft's (same as Yaesu's) four digit band code to individual signals for each ham band. Decoders are available from Top Ten Devices, Array Solutions, Unified Microsystems, and perhaps others. If you put the Six-Pak controller within reach of the spotter station, and add a manual/auto switch to that channel of the Six-Pak, the spotter will be able to select unusual antenna combinations. Otherwise, the spotter can just change bands on the radio, and the BPF's and antennas will follow automatically.

Re: [Elecraft] KX1 help
[..] Solder the other end of the coax to a PL 259 plug and you should be done. I believe the jack on the KXV1 is a BNC connector. Right? Not sure what the PL-259 gets you. Converting from PL-259 back to BNC is just another RF-speedbump. It might not matter though. I tend to try to avoid converting coax connectors and instead put on the connector for the application. On the coax, here's what I thought, but I could be mistaken: For portability I was going to mention RG-316, it's O.D is just less than 0.100 and therefore really light in the backpack, but the matched loss is substantially higher than other selections. I haven't tried RG-303 (Belden 84303) but the O.D. is only 0.170 and the matched loss is just a bit less than half of RG-316. (1.2 db at 10Mhz per 100ft, 4.1db at 100Mhz per 100ft) compared to RG316 (2.7db at 10Mhz at 100ft and 8.3 (wow) db at 100Mhz at 100ft). Your rig is going to be operating at frequencies lower than 20m so 1.2db at 10Mhz per 100ft would be ok with me, If you use a feedline that is 40ft or so or less from the portable antenna (backpacking situation) that would be just fine. There's other narrow O.D. coax listed in table 19.1 of the ARRL handbook, RG-400 also has a narrow O.D. and decent loss values. Just depends on how much weight you want to carry with you, availability of connectors for the various coax. If weight isn't an issue, I'd go with RG8-X to get started, not the absolute best coax but cheap and fairly good dB loss figures for the bands you can work with the rig you have. -jeff ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3: The ARRL RTTY Round UP
Roger that regarding shift and width granularity! I had great success (for me) in RU using my 200 Hz 5 pole filter with the DSP width set at 200 Hz and moving the filter offset frequency (FLx FRQ) about 30 Hz from normal to center up the passband while looking at band noise with MMTTY. I used 1275 Hz Mark frequency. DSP LO was 1.3 KHz and HI was 1.5 KHz. Moving the filter offset allowed both mark and space signals to come through at similar amplitudes. If the DSP resolution below a few hundred Hz would switch to 10 Hz resolution, it would be a real help and should probably alleviate jockeying the filter offset. In my case sensitivity might improve a bit, too since my mark frequency was 25 Hz outside of the stated DSP passband! With 10 Hz resolution, the DSP could be set something like 1260 through 1460 Hz. (or whatever produces the best looking response in the desired audio passband) without tweeking FLx FRQ. At any rate, even with 50 Hz granularity this setup allowed me substantially better copy of weak TTY signals in a crowded band than did the DUAL PB in the more conventional manner (while using MMTTY). The radio performed flawlessly for me in my first RTTY Roundup (Single Op, Low power, 530 Q's, 56 Sec, 35 countries, all SP). The radio was run in the FSK D mode with data decoding always running. Incidentally, my fancy new LCD computer monitor uses a capacitance touch power switch which would frequently turn off the monitor when I was transmitting on certain bands (40 or 20). But I never lost a Q because of this because I could always copy the RTTY on my K3 decoder display and would occasionally grab the paddles to send if the stations call had not yet been entered in the logging program (N1MM). It always took a few seconds for the monitor to reinitialize once I was able to turn it back on though it seemed much longer than that in the contest. My next ham radio task may be modifying this monitor. 73, Mike Guy, K2AV wrote: Changing SHIFT and WIDTH granularity to 10 Hz from 50 would improve CW useability as well. A lot of us have formed contest operating habits and tactics based on analog SHIFT and WIDTH functions. Like a combination of a small shift and (sometimes) a lesser width change to put someone up or down just a bit farther down the passband and keep the same skirt frequency on the opposite side of the passband. 73, Guy wayne burdick wrote: All RTTY issues noted, Dave -- thanks.

[Elecraft] K3: How to determine TX Frequency Over Serial Port
Hi all and a Happy New Year, I need to determine the K3 TX frequency over the serial port and I think I know how to do it but thought I would check to see if there is a better solution. The steps I think I need to take are: Determine the TX VFO using the FT; command Depending on the response (FT0; or FT1;) get the VFO A (FA;) or VFO B (FB;) frequency I may also need to take account of the XIT offset in a similar manner. I can't see any other way to do this without reading a lot of info I'm not interested in but open to suggestions. I've searched for a command that gives me the TX frequency directly but can't find one.

You cannot do FSK on the same port as radio control (unless you are using the KY; software command, which the vast majority of software, including MMTTY, does not support). If the port you use for FSK is a USB-to-serial adapter rather than a true serial port, you will need to use the EXTFSK plugin for FSK. In MMTTY you must configure a serial port for PTT (different from the radio control port) in order to use FSK. However, you don't actually have to use this port for PTT; you can configure it, enable it for FSK, and then just not connect aany PTT line to DTR or RTS. MMTTY gives you two other alternatives: you can do PTT either by software control or by keying DTR and RTS on the radio control port. If you use MMTTY's PTT port for FSK and/or PTT, both FSK and PTT will require keying transistors, because these inputs on the K3's ACC connector are TTL-level, not RS232 (FSK from TxD via a keying transistor to pin 5, PTT from either DTR or RTS via a keying transistor to pin 4). If you choose to do PTT using the radio control port (either DTR or RTS), you will not need a keying transistor for this line, because this is an RS232-level input on the K3. For the radio command protocol, just choose Kenwood. The K3's AFSK A mode is operationally equivalent to FSK D, but does not require an FSK keying circuit; instead, you need an audio cable between the sound card's line out and the radio's LINE IN jack. 73, Rich VE3KI ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 restistance check.
John, I assume you mean U6 on the RF Board. Do you have the Control Board plugged in? You should not for this resistance check. Unfortunately, no one answer can be given. That point is the 8B voltage rail, and there are many things connected to it - the problem can be at any of them. I suggest you download the K2 manual and using the Find function in Adobe Reader, go over the schematic and identify all the components that are connected to the 8B rail. Then check each one of them on the RF Board. Look for solder splashes that might be shorting this circuit to any other circuit. Check the values of all components you identified, and be certain the ICs, transistors and diodes are oriented correctly - the Parts Placement diagram is a big aid in determining component orientation. Good luck with it. 73, Don W3FPR John wrote: Hello all. I am reading 50 ohms at U6 pin 8 instead of the manual 100 ohms figure. Can someone please tell me where I may look to find a problem?

Re: [Elecraft] KX1 help
If it is a BNC connector, then obviously that is the connector to use. Unfortunately, I do not have that radio. The K2 does have the PL 259 type connection and so I apparently wrongly assumed so did the smaller radio. It was certainly never my intention to suggest that one used an improper connector and then convert to what is actually needed.

I believe the jack on the KXV1 is a BNC connector. Right? Not sure what the PL-259 gets you. Converting from PL-259 back to BNC is just another RF-speedbump. It might not matter though. I tend to try to avoid converting coax connectors and instead put on the connector for the application. On the coax, here's what I thought, but I could be mistaken: For portability I was going to mention RG-316, it's O.D is just less than 0.100 and therefore really light in the backpack, but the matched loss is substantially higher than other selections. I haven't tried RG-303 (Belden 84303) but the O.D. is only 0.170 and the matched loss is just a bit less than half of RG-316. (1.2 db at 10Mhz per 100ft, 4.1db at 100Mhz per 100ft) compared to RG316 (2.7db at 10Mhz at 100ft and 8.3 (wow) db at 100Mhz at 100ft). Your rig is going to be operating at frequencies lower than 20m so 1.2db at 10Mhz per 100ft would be ok with me, If you use a feedline that is 40ft or so or less from the portable antenna (backpacking situation) that would be just fine. There's other narrow O.D. coax listed in table 19.1 of the ARRL handbook, RG-400 also has a narrow O.D. and decent loss values. Just depends on how much weight you want to carry with you, availability of connectors for the various coax. If weight isn't an issue, I'd go with RG8-X to get started, not the absolute best coax but cheap and fairly good dB loss figures for the bands you can work with the rig you have. -jeff ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3: The ARRL RTTY Round UP
From: Joe Planisky jp...@jeffnet.org I agree that finer steps to SHIFT would be nice, but until then, wouldn't it be possible to center the audio using RIT? So far as the audio passband one hears, the RIT is no different than the main tuning knob. If one is mainly hearing 2150 to 2450 with a 300 hz filter, and you are trying to receive 2125 and 2295 changing the RIT to get those tones will still put the 2100 on the filter skirts. Only the shift will move the heard audio passband down to center around the standard tones. On a run frequency, one usually locks the TX frequency, and adjusts shift/width of passband for the regular listening width and centering, saving RIT for listening only for temporary excursions to someone who calls really high or low. Contest programs can reset RIT when a QSO is logged. They will not change shift. RIT is expected to be temporary per QSO. Shift is considered a manual adjustment that the program leaves alone. 73, Guy. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Six meter birdies.
I'm still playing with my new K3 and finally got around to listening on 6-meters. There are so many birdies as to make it unusable. At first I thought they might be external, and some were generated in my Lenovo laptop, but shutting it down and terminating the K3 antenna port with a load doesn't eliminate them. When listening to the same frequencies with an Icom IC-R10 with a whip antenna next to the K3 I don't hear a thing. Ideas?

[Elecraft] K3 Enhancements, SMD resistor sizes
I'm putting together an order to Mouser anyway, so figured I'd order the SMD parts for the AF mods and for the Synthesizer ALC mods, but it's not clear what physical size they are. To save me from dissassembling the radio twice, can someone tell me what these sizes are? 73, doug ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] No Speaker Output from Internal Speaker?
I have an identical problem. Also the output from the rear headphones jack is to one ear only and the packet output is null with the default setting. Because I also have another problem (PA trips at high power on 10m only), the radio is going for service.

Most of the resistors in the K3 are 0603 size, some are 0805. I used all 0805 when doing the recent mods, including the KSYN3 ALC and line audio out mods.

[Elecraft] Contesters and Band Conjestion

(IMHO) The reality of worldwide frequency allocations is that on some bands, contesters MUST violate bandplans to work stations outside their own country. On 40M, for example, JA stations have a rather limited bandwidth to operate RTTY and it's pretty low on the band. On 80M, RTTY cannot operate above 3600 kHz due to a rather dumb error made by a low level FCC clerk who rewrote the ham Rules several years ago. One of our club members, operating from Aruba (in the Caribbean) made 409 contacts on 80M, 809 on 40M, 1,127 on 20M, and 869 on 15M. This is in 24 hours of a 30 hour contest period. That means there were at least that many active stations that had to cram into the spectrum that the FCC gives us. There are similar conflicts with SSB operation worldwide, especially on 40M. Our club alone had 77 members on the air in the contest. There are MANY times when I can tune across 80M during hours of darkness and hear NO signals at all. There are MANY times I can tune across 40M and hear fewer than a dozen CW signals and half that many PSK signals. On a non-contest weekend, perhaps twice that number. Assuming two people per QSO, that means casual QSOs are sharing a band with a FAR larger number of contesters. In other words, casual operators are simply a few percent of the total number of hams using the band. Heck -- a good contester can easily run 50 QSOs per hour using a few hundred Hz bandwidth (if he's got a K3) and the top contesters run at twice that rate. The good contesters I know all listen before transmitting, and ask if the frequency is busy if they hear nothing. But band conditions change, sometimes rather quickly. A station can be running on a frequency for an hour, and conditions change so that you and he are now hearing each other. No one is being discourteous, it's just band conditions. Last week during Stew Perry, I'd been running a frequency for a half hour, and was making Qs as far as the east coast (I'm near SF). A W2 shows up, doesn't hear me (he probably had a big noise level, or maybe was on a Beverage pointed to EU), so no matter how many times I told him QRL, he ignored me. Discourteous? Probably just his local noise. Note also that contests never use the WARC bands. 30M is a great band for CW ragchewing, and I've never heard it crowded (except when a couple of really rare DXpeditions are there at the same time)! 73, Jim Brown K9YC VP -- Northern California Contest Club ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2:Flakey KIO2 Communication with HRD
I posted this on the HRD Forum with little response so I'm trying for the collective wisdom of this august group. I have two radios: a FT1000 MarkV Field and a K2. Both are connected through separate USB bridges using the Proflif chip set to my USB port on a computer runniing XP SP3. Both radios communicate fine with Logger32. Only the FT1000 seems to be working with HRD; the K2 appears to be loosing characters as the frequency drops digits and/or the mode as read by HRD changes erratcially. I've triple checked the configuration and have loaded the current drivers from the Prolific website. I have also swapped the K2 between the 4 USB bridges I have and the problem moves with the K2. Perhaps I should forget HRD and stick with logger32 but I would like know why this is occuring.

[Elecraft] Mildly confused - Assumed filter width and what I see in waterfall do not match
I have been using several programs (Cocoamodem, mostly) to do PSK31, via Data A. Instead of being able to use the full 4khz waterfall bandwidth available in, say, Cocoamodem, I have been limited to the available width in the only filter I had in the rig, the 2.7 khz 5-pole appeared to limit me to about 2.7 khz. So, I added the 6 khz filter, set it up for SSB (and enable ESSB, 4.0 khz). I now show 3 khz (500 to 3500 hz) in the waterfall. I suspect I have overlooked something, but it is not clear to me what. Does anybody have any idea? Thanks! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K2:Flakey KIO2 Communication with HRD
Clark, If you can possibly operate the K2 from a real serial port, try that. One problem with USB to serial adapters is that the run best at higher speeds - the K2 can only handle 4800 baud and that may be too slow for the volume of information that is being passed between the K2 and HRD. 73, Don W3FPR Clark Macaulay wrote: I posted this on the HRD Forum with little response so I'm trying for the collective wisdom of this august group.

Re: [Elecraft] Filters
We had good success this week end in the ARRL RTTY RU with the 500 hz roofing filter and a DSP setting of 300 hz most of the time. At times we went to 250 hz. and used the 250 hz roofing filter when the going really got tough. We are talking about a serious effort to win # 1 which we have done in the past but most years we are second or third multi-op. You really did not say if it is for RTTY general contacts, chasing DX or contesting? That is the key question! If it is the first two then a 500 hz roofing filter and and use the DSP to narrow down more when wanted would be all you need. The 500 hz with DSP would be fine for CW as well. If you want to contest on CW and RTTY then adding the 250 hz roofing filter is worth having. For CW if you want the ultimate then also adding the 200 khz roofing is great for contest CW and will work in a huge pileup on RTTY even though it rolls off the edges. We did use it a fair amount this week end. If you are not seriously into CW contesting but want to do some serious RTTY contesting the most you need it the 250 hz roofing filter. It is far two early to say but we did not seem to be able to see an advantage to the Dual PB but like I say we tried it some and could see no improvement and a couple of times we thought we seen it was worse so we quit using it. Howeverthis was a quick gut feeling decision made in the midst of the competition so we may ultimately find it is OK. Future firmware updates may make it more effective. Using two K3's in some serious contest efforts this season starting with the IARU with a number of top 10 finishes according to unofficial results I have to back up what has been said on the users group many times and that is IF you are not in some very serious and I mean serious contest efforts with extreme crowding and big signals there is ABSOLUTELY no need to spend a lot of money on filters!!! One for SSB, the one that comes with the radio is excellent and a 500 hz roofing filter for CW and RTTY is absolutely all you need and use the DSP! I can guarantee this to be true! I am of course assuming you don't want to do FM and AM. Ed W0SD ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K-2: my perosnal experience
Hello, Nic... Happy New Year to you and yours. Yes, the K2 is the ultimate experience in kit building. My #5957 is the prime radio here. I've added the 100w amp, SSB, noise blanker, and DSP. All work as advertised. I agree with your observation about the production design. When every hole, screw and fitting fell into place, perfectly, I almost didn't care how the radio actually performed. It was a joy just to watch it come together without a single problem. I've built stuff before, my own and others, and I've never seen anything that comes close. The K3 people - unless they first had a K2 - just don't know what they're missing g. ...robert VK2DX wrote: The K-2 was ordered on December 17th and No. 6653 arrived 3 days later. I have to say I did not know what to expect- I was just looking for 'something' to keep me busy during the summer holiday (I am located in Australia). Well let me just say that I got my money worth of pleasure even before the radio was completed! I am a master watchmaker by trade so I can not comment on electronic aspect of K-2. However from the mechanical perspective the kit surpassed all expectations. The quality of instruction manual, PCBs, relays, connectors, individual components is just amazing. Everything fitted together perfectly and I got the radio working in a first go! The bit that I enjoy the most is winding of toroids. I love the magic of radio getting alive, especially when LCD flashed Elecraft for the first time. And most importantly I've learned a lot! Since English is not my first language, I'll keep this rapport brief. I took 175 photos of assembly process, including on-air test :http://vk1aa.com/K2/k2.html The very first contact made was with JE1RZR over the distance of 9,250 Km on 14,054 MHz. (Manabu was operating K-2/100 !). Few minutes later under rather poor band condition I also worked FK8DD, BV7, ZL1. Just after my sunset, I had a lovely QSO on 40m with another JA1 and ZL2- all with 5W out into home-made vertical antenna. I would like to thank Wayne and Eric for such a wonderful experience and to many of you on Elecraft forum for your unselfish assistance to Ham community. 73, Nick VK2DX Sydney - Australia. -- Robert G.

Re: [Elecraft] Contesters and Band Conjestion
We CW casual QSO people do have trouble with RTTY people all over the place. Many times 30 meters no good for short path QSO's. We need to put pressure on FCC or whoever to allow CW on at leat a couple of the 60 meter channels setup for SSB only. Would be easy about 200 Hz lower than supressed carrier frequency and still be in the alloted channel, and for the most part, not QRM SSB on same channel. But then, too many commissioners and lower level people are NOT ENGINEERS! This would allow casual CW QSO's on a band that propagation would probably be possible for short path stuff when 30 meters is tanked for that. Thanks to the reduction of 80 from 3500-3600 instead of 3500-3700 the RTTY guys are in a quandry, NTS die hards in a quandry and CW people in a quandry! The other bands were more sensibly reducedwhy didn't they follow the same pattern for 80 meters and the NTS+CW+NTS guys would still be where they were before basically! 80 meters has been terrible since the change.
