Re: [Elecraft] Problem with K3 and Windows 7
The OS probably reassigned the port number it was using for the USB driver. The human has no control over what port number is used by the driver. Any program you are running which is looking for the K3 on a serial port may need to have the port number respecified after an OS change. 73, Guy On Sun, Nov 15, 2009 at 10:23 PM, Craig Taylor cstaylo...@yahoo.com wrote: I updated my computer to Vista then W 7.

Re: [Elecraft] K3 Firmware Req for SWL band and Using Memories
Hi Steve, How about a Take me back to the ham band macro button? Yes, that's essentially what the scheme I described with the M1-M4 buttons does. You wouldn't have to set up all 4 buttons like I did. Here's how you could set it up with just one: 1. Go to the 160m band. 2. Set VFO A to your favorite frequency in that band (say, 1.9 MHz) 3. Set the mode to whatever you want. 4. Press VM then the M1 button (or M2, M3, or M4) 5. Now, any time your VFO is in the range of 0.5 to 2.9 and you press MV followed by M1, you'll go to 1.9 MHz and the mode will be set to whatever you used in step 3. 6. Now go to 80m and repeat steps 2 - 4, using the same button in step 4. Repeat for 60m, 40m, 30m, etc. All 11 bands. Once you have all 11 bands set up this way, then no matter what frequency you're on, anywhere in the K3's range, pressing MV,M1 will take you to your favorite frequency in the nearest ham band. You don't have to know the boundaries or anything. If you really want a one-button solution, set things up as described above and then try this macro in PF2: SWT23;SWT21; (which just taps the MV key followed by the M1 key.)

Re: [Elecraft] K3 Firmware Req for SWL band
I wouldn't mind keeping BAND as a hamband-only control. However, in this case it would be nice if the K3's band boundaries usng this control did conform to the legal ham bands (i.e., 40m should end at 7.000, not 6.000 MHz). I suppose this would mean, for instance, when you wander below 7.0 MHz, that BAND should remember 7.000 and no lower. (But I guess this would be complicated by the differring band assignments for different jurisdictions) I would like to have a coarse tuning rate of 1.0 MHz so that any 1 MHz band in the entire 30 MHz HF coverage could be accessed within one revolution of the VFO knob. I think this would be slightly more convenient than direct frequency entry. I would also like to have some macro commands for manipulation of frequency memory. With this capability you could program a band bank macro that would copy a range of ten frequency slots into the 00-09 quick memory positions. Then you could switch in a bank of ten SWL frequency pairs, or a bank of SSB, or CW, AM Bcst, etc. Then use the MV x quick memory to access the bands in your currently selected bank. 73, Drew AF2Z On Sun, 15 Nov 2009 16:30:34 -0500, Steve N4LQ wrote: let me make this an offical request for FW if it's possible.

Re: [Elecraft] K3 Firmware Req for SWL band and Using Memories
The SWL band could be placed between 6 meters and 160 meters in the BAND switch's rotation, and would always contain the last non-amateur frequency used. Let it fall in frequency sequence. If one used it for MW broadcast (US AM band) it would fall between 6 and 160 but if it was being used for WWV at 10 MHz it would fall between 40 and 30 Meters. This is the way both Icom and Yaesu do it. The existing CONFIG:BND MAP menu item could be used to enable/disable this feature: SWL IN would enable the new feature, SWL OUT would restore the existing modus operandi for those who prefer it. Alternatively, SWL OUT could simply disable storage of a frequency outside of the specific amateur band. If one tuned to WWV on 10 MHz then used the band up/down to go to 20 Meters, the 30 Meter bad would be reset to 10.100 and similarly on the other bands. It should not be too difficult to reset to the bottom of the band since the K3 already knows the band edges to disable out of band transmit. 73, ...

[Elecraft] Elecraft CW Net query
Good Morning, I would like to ask if a time change is in order. I am thinking of moving both nets earlier due to the poor propagation we are experiencing. The current times are: Monday z (Sunday 4 PM PST) 14050 kHz Monday 0200z (Sunday 6 PM PST) 7045 kHz I am thinking of moving the 20 meter net to 2300z and the 40 meter net to z. This lets me eat dinner at the same time but both nets will be done. It also may allow folks further east to check in before they need to get to bed for their Monday appointment with work or school. I would like some comments on the proposal. This would be the new schedule if there is agreement: Sunday 2300z (Sunday 3 PM PST) 14050 kHz Monday z (Sunday 5 PM PST) 7045 kHz Thank you for your continued support and thank you to the Elecraft folks for letting us have our fun. 73, Kevin.

That's what happened when I upgraded my computer to Windows 7. In my case I have two real serial ports via a Vscom PCI200L, added by me. Before the upgrade the ports were COM1 and COM2. After the upgrade to Windows 7 they were COM3 and COM4. I was able to go to CONTROL PANEL|DEVICE MANAGER|MULTI_PORT SERIAL ADAPTERS. There I double clicked on Vscom PCI200L controller, then clicked on the advanced tab and was able to rename the ports from 3 and 4 to 1 and 2. I've seen cases in the past where you were not able to rename the ports. I think it's a function of how the manufacturers implement their drivers.

[Elecraft] K3 in AM-Sync Mode Receiving WWV
I have been trying out the new AM-Sync mode by listening to WWV on its 5 frequencies and am seeing something that I wonder is a problem for my K3 (#1292) or is it being seen by others as well. I have observed that on the 10MHz WWV frequency only, that my K3 will momentarily unlock with the frequency jumping either up or down by as much as 200 Hz. The frequency quickly, less than a second, will be corrected, and all is well again. This occurs at what appears to be entirely random timing, from several minutes, to as often as a few seconds. I haven't noticed this happening on any of the other WWV frequencies that I have observed, being all of the rest except 2.5MHz which is not open to me this morning. I did notice this yesterday on 10MHz, but did not check the other frequencies until today. I find it difficult to believe that WWV is having jumps in its 10MHz transmission. Has anyone else noticed this, or do I need to be giving Elecraft help desk a call?

Re: [Elecraft] K3 in AM-Sync Mode Receiving WWV
This problem may (or may not) be caused by selective fading, causing the real WWV carrier to disappear for a moment, whereby the K3 then locks up to one of the sidebands, perhaps from the 100 Hz time data, then returns to the main carrier when it again is strong enough. Of course it may be something else entirely, but that is one possibility.

Re: [Elecraft] K3 in AM-Sync Mode Receiving WWV
... I find it difficult to believe that WWV is having jumps in its 10MHz transmission. Has anyone else noticed this, or do I need to be giving Elecraft help desk a call? AM Synchronous receive is in its early stages. We are aware of the behavior you describe and are improving the algorithms we are using. Also, keep in mind that AM-S is a tool in your toolbox. There will be times when regular AM envelope detection will work better, and times when using the SSB demodulator will provide superior results. 73, Lyle KK7P __ 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] K2 and DX
This weekend was fantastic for DX. 15 and 17 meters were open most of the day at my location in Wyoming. I worked a Japanese station on ten watts with my K2. He asked me to repeat my power level three times. Apparently, he couldn't believe I was only running 10 watts CW. Of course the propagation had a lot to do with it. Then there is my antenna...a home-brewed, non-resonant, multi band vertical. Okay, maybe the vertical didn't have a lot to do with it but, who cares. I also worked the Canary Islands on the same ten watts. So, I figure it is a combination of propagation and K2 mojo. This weekend felt like the peak of a sunspot cycle rather than the bottom. I also heard France and Germany. DX isn't as easy to come by here in the middle of the country. I hear hams on the eastern seaboard working DX like it's next door.

Re: [Elecraft] K3 DVR in SS
I would guess what you're really asking for is for is for the DVR to play a message if it's invoked when PTT is active and to keep the PTT active even if you then drop it, but to terminate if it's active and then PTT is pressed? That way, it can call CQ, you can terminate it and fill in the gaps with a PTT and then complete the exchange by invoking DVR again and have it go on to call CQ again. That's what I would want too. 73 de M0XDF, K3 #174 -- Times are bad.

Re: [Elecraft] K3 in AM-Sync Mode Receiving WWV
This is exactly what's happening, and we're looking into a possible change in the way we handle it.

Re: [Elecraft] K3 Firmware Req for SWL band and Using Memories
I can also get around the bands (ham and SWBC) just fine. I suppose the BAND switch is straight forward if you know that that it divides the K3's entire HFcoverage range into ten bands, each one having an amateur radio allocation somewhere within: 0.5 to 3.0 MHz 3.0 to 4.8 4.8 to 6.0 6.to 9 9 to 13 13 to 17 17 to 19 19 to 23 23 to 26 26 to 30 It is understandable how general coverage users can be confused.

I have observed that on the 10MHz WWV frequency only, that my K3 will momentarily unlock with the frequency jumping either up or down by as much as 200 Hz. The frequency quickly, less than a second, will be corrected, and all is well again. This occurs at what appears to be entirely random timing, from several minutes, to as often as a few seconds.

I feel the 10 MHz WV transmitter has some apparent frequency modulation and audio distortion not present on any of the other frequencies (or on WWHV when I can hear it).

I ran the main IF to the main receiver on my Flex5000 and the KRX3 subIF to the subreceiver on the Flex5000. Everything seems to be OK in terms of how I chose to get the IF from the KRX3. I am working a long day tomorrow as well as Saturday AM, but I am hoping to get a chance to run up to the hilltop and pick up the audio cables and then get the LP Pans hooked up Saturday afternoon. This is a brief summary of what I did with the KRX3: I used the Z1 as buffer amp inside the KRX3. I got +12V from a 12SA pad near to P86A. Power and RF connections to the Z1 were done from the underside of the Z1. I took IF output from KRX3 from P86A and used RG174U to take this to input of Z1. I mounted Z1 on an unused FL position using a 1/2 inch standoff. I mounted a dual female SMA connector in the REF hole at the bottom corner of the K3 just below the official IF out BNC. I then used a right angle premade small surplus coaxial cable to take the signal to the KRX3 and thus the Z1. I entered the KRX3 at the back left corner opposite to J92, because there was already an opening there. I ran the coax inside the KRX3 bottom shell, beneath the main KRX3 PCB. I brought it up to the Z1 by running it through an unused hole meant for an FL standoff. At first check, using the two subreceivers on the Flex5000 to receive the IF signals from the K3, the main K3 and the KRX3 subreceiver IF outputs seem to be equivalent. When constructing the Z1, I used the -U [Universal] options, not the K2 options. I chose to set it up for zero gain, and thus chose R907 to be 499 ohms, and R905 to be 4.7K, as per section 2.3.3 of the Z1 manual. I attached a jpg file with the two IFs from the K3 going to the Flex 5000. The K3 main IF goes to the main Flex receiver and the DRX3 sub IF goes to the Flex sub receiver. The signal is Radio Moscow on 40 meters. 73, Roger Rehr W3SZ http://www.nitehawk.com/w3sz __ 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] K2 and DX
Hi Gary, I wouldn't sell your vertical short. When I have time to get into the contests I've always use a vertical and find that the farther away the station is the easier it is (most times) to break the pileup when I use a vertical. The low angle radiation advantage is noticeable. My best, most exciting contact was with Seychelles in CQ Worldwide on 20m a few years ago. I was using my KX1 at the time, running about 3 watts into a vertical. He gave me 559. I think the other trick was to re-visit 20m after everyone else had abandoned it for 40m in the afternoon. He was sitting there, calling and calling. I couldn't believe my luck. I'll be in CQWW later this month with a 20m elevated vertical with four 5 ft radials! 73, Ken Alexander VE3HLS __ 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

A diode across the leads oriented to it is normally reverse polarity (anode to ground, cathode to +) will conduct when that surge occurs and keep most of it from reaching the K3. Depending upon the inductance of the solenoid that surge can be quite large, producing many times the 12 V that was applied with rather large current for a brief interval. It's important to choose a diode that can handle those surges without failing. Power supply diodes are a good bet for a fairly heavy duty relay. Ron AC7AC -Original Message- Now that's a good idea.

Re: [Elecraft] [MM] W2 review - and why the diode...
Hello David Why the diode? Well, any relay driven by a solid-state device should have a diode across its coil (in reverse polarity!) to short reverse voltage spikes. Transistor are rather fast switches... and such spikes would damage them. Never drive a relay from a transistor or IC without such a parallel diode! 73 Richard - HB9ANM David Ferrington, M0XDF wrote: Now that's a good idea.

Re: [Elecraft] RIT knob removal?
If it's a K3, it's as simple friction fit with a spring to hold the knob securely; just pull it off. Be sure to you don't lose the spring insert when it comes off (it's a flat metal spring shaped like the end of the shaft) and orient the knob so the flat is aligned with the shaft when replacing it. If it's a K2, the knob is held in place by a set screw that requires a .050 (1.3 mm) Allen wrench. Ron AC7AC -Original Message- Can anyone suggest the proper way to remove the RIT/XIT knob?

[Elecraft] Elecraft CW Net query - reprise
Good Afternoon, This morning, before dawn, I sent a query message about changing the net times. I have gotten many favorable replies. However, there seems to be an error in my times (what else is new?) The proposed Zulu times are what I had intended. But for the 40 meter net I did not change the local time correctly. I want to put one hour between the start times of the two nets instead of the usual two hours. I will make and eat dinner after the nets are done. == The current times are: Monday z (Sunday 4 PM PST) 14050 kHz Monday 0200z (Sunday 6 PM PST) 7045 kHz This would be the new schedule if there is agreement: Sunday 2300z (Sunday 3 PM PST) 14050 kHz Monday z (Sunday 4 PM PST) 7045 kHz = A request has been made for a comprehensive listing of time zones. Being lower 48 centric I will stick with the usual Eastern, Central, Mountain, and Pacific time zones. The rest of you will have to fend for yourselves :) So3 PM PST is 4 PM MST and 5 PM CST and 6 PM EST While 4 PM PST is 5 PM MST and 6 PM CST and 7 PM EST I am glad we do not have really odd time zones like they have in other countries. Some of them are 45 minutes different from the one next to them. I have a hard enough time here. I think if I lived in one of those countries I would simply stick with Hopi time: it is always now.

Re: [Elecraft] K3 Beringer HA400
Steve, Just an idea - have you tried it on LINE OUT? It may be that you are overdriving the input of the Beringer. The other possibility is that you have an RF in the Shack problem and the Beringer is reacting to the RF. Try it when connected to a dummy load or in TX TEST. If that 'fixes' the problem, you have some antenna work to do to keep the stray RF out of the shack. 73, Don W3FPR Steven Pituch wrote: Hi All, I tried using these two items together and am getting scratchy audio in the headphones when I speak on USB even though the monitor is set to zero.

[Elecraft] SPLIT Macro revisited
The good folks at Elecraft provided me with a solution to my earlier posted problem. Using the original macro for split: SWT13;SWT13;FT1;UPB4;RT0;XT0;SB1;BW$0080 Works fine if you only intend to use it on cw. But if you go to ssb, it has two problems: a) it doesn't switch modes and b) it sets the vfo B bandwith to 800 hz which isn't so good for ssb Here's the fix . a) change the macro to add the word delay (no quotes) in between the two SWT13 statements b) remove the BW$0080 statement the new macro looks like this: SWT13;delay;SWT13;FT1;UPB4;RT0;XT0;SB1 The mode now switches properly. You will have to manually set the bandwidth you want for vfo b in ssb and cw, but the good thing is the K3 remembers it.

Re: [Elecraft] K3 Firmware Req for SWL band and Using Memories
A rapid-transit shortwave band select would be pretty easy with the existing features and firmware of the K3.set aside a group of memory channels, say 90-99, assign a frequency or frequency pair(A/B vfo) from each shortwave band to each of the memories, label 60M-49M-31M-25M-19M-16M-tertiary bands etc, 41M if you want a SW Rx mode/filter different from your 40m usual mode, add asterisks to the memory labels and bandhopping is yours. Tune from there. For more convenience there is the serial port and the family laptop. Ham band switching stays ham band only, simple and direct. I bandswitch by MV 1 thru 9, from 160-10 meters, with 60 meters selected as above and in the K3 manual. VFO A is starting point in SSB segment, VFO B the CW end. Always the same start/filter/ bandwidth, no surprises from the K3's understanding of band limits. Band UP/DOWN is very handy to look quickly at another band and return same freq with only two keystrokes.

[Elecraft] K3 feature request--remove monitor from line out
Currently when operating RTTY using FSK (data mode FSK D), RTTY monitor audio is routed to line out--both left and right stereo channels. I am routing main and sub receiver audio to two sound cards in a SO2V configuration using N1MM Logger. The problem with routing monitor audio to line out is that RTTY transmitted from either digital interface is picked up by the other sound card, so that the transmission is printed on the other digital interface screen. As a result I get my CQ calls printed in between the signal I am trying to copy in SP mode on the sub receiver. Setting monitor to zero eliminates the problem, but I like to set a low-level monitor audio just to track when I'm transmitting. Could there be an option in LIN OUT to mute monitor audio routing to the line out connections? Still want to hear it in the phones, of course.

Re: [Elecraft] K3 Beringer HA400
Steve, Thanks for those details. I am almost certain Jim Brown K9YC would refer to this as a pin 1 problem, and that is the reason that bypass caps are not likely to help. You might be able to minimize it with some work to the Beringer - look carefully at how the cable shields are routed. If they connect to the PC board directly, this is the classic pin 1 problem - they should be connected in such a way as to route the energy on the outside of the shield to the *outside* of the enclosure rather than going first to the PC Board ground plane.. Perhaps you can make some mods to that equipment, perhaps it is just not worth it. Many enclosures for inexpensive equipment are plastic, so there is no way to avoid the pin 1 problem in those cases. Once the RF energy gets inside the enclosure, there is no telling in which circuits it might cause problems. In the hamshack, metal enclosures for audio equipment is almost mandatory, and if designers would pay attention to the pin 1 situation, many user headaches would be solved. Note that in days of old, connectors used to mount on the enclosure, and thus prevented this pin 1 problem because the RF would flow on the outside of the enclosure and not make it to the inside, but in more modern times, connectors mount directly on the PC board and may or may not connect from the board ground plane to the enclosure - and even if it is connected to the enclosure, it is likely to be on the inside - RF travels on surfaces due to 'skin effect', so visualize the paths - the inside of a metal enclosure is a different conductor than the outside at RF frequencies - and you will see the difficulties presented. 73, Don W3FPR Steven Pituch wrote: Don and Dick, It does not occur with TX Test However, it is not any worse if I use my ALS600 at 400 Watts, or I totally disconnect the amp and just use 50 Watts out of the K3.

I received my new 400 Hz filter midway through the WAE RTTY contest and since I wasn't really contesting, took the time to install it. I guess I'm a little underwhelmed so far, but to be fair I wanted to compare it under fire with the 2.8 KHz filter I have been using. (I expected less buckshot from out-of-the-passband adjacent signals with the narrower filter, although this may be a commentary on the lousy transmitted signals) I continued to allow the 2.8 KHz filter to be used on data modes because if I decide to use the PSK modes, I might want the wider BW. Problem is... when switching the crystal filters manually, the DSP bandwidth defaults to 2.8 KHz when I select the 2.8 KHz crystal filter and 400 Hz when I select the 400 Hz crystal filter, even though I may have previously reduced the Width setting to something narrower. Likewise, when in Data mode with the 2.8KHz filter selected, hitting NORM defaults to 400 Hz BW, which again selects the 400 Hz filter. I suppose this is by design, but why can't the radio simply maintain some independence between the crystal and DSP filters?

Re: [Elecraft] [K3] Filter selection question
Hi Wes, This is by design. Selecting a filter manually via XFIL normalizes the DSP bandwidth to the crystal filter bandwidth. Using any other method (WIDTH, SHIFT, LO, HI) selects a crystal filter based on the DSP bandwidth (which you can see by rotating WIDTH, or just tapping it twice). If you want to quickly alternate between two bandwidth settings that may not be the normalized values, you can use the floating presets (I/ II switch, part of the HI/WIDTH knob). These presets are saved per- mode. Typically I set preset I to 500 Hz and preset II to 100 Hz. In addition to the floating presets, you can create two fixed presets in each mode. Please see NORM1/NORM2 in the owner's manual. Regarding performance: There is absolutely no question that inserting the 400-Hz crystal filter will provide dramatically better results when large signals are present ( about S9+10). With the 2.8 kHz crystal filter selected, signals within the 2.8 kHz passband but outside a narrower DSP bandwidth could activate hardware AGC. This reflects the K3's very crystal-filter-centric design philosophy: use the narrowest 1st IF roofing filter consistent with the present mode. Other manufacturers put less emphasis on this because they typically can't offer narrow 1st IF filters (3 to 6 kHz or wider, vs. the K3's minimum bandwidth filter, which is 200 Hz). 73, Wayne N6KR On Nov 16, 2009, at 4:23 PM, Wes Stewart wrote: I received my new 400 Hz filter midway through the WAE RTTY contest and since I wasn't really contesting, took the time to install it.

[Elecraft] Lost aux rec
It's been working all along but lately sometimes i notice that the Sub rec is slow to recover. Audio is weak and then comes alive. Tonight after working some DX, split of course, i went to 30 meters to work the 5N0och and found that while i get audio out of the main rx, i hear noise from the sub but no sigs. Like the antenna isn't connected but i know it is because it's been working and i've not changed anything. TI powered down both the Sub and the whole radio a couple of times but have done no reset or anything. Time to bring the FT-990 back on line i guess. Me thinks something has crashed.

Re: [Elecraft] K3 Beringer HA400
Thank you Don, The HA400 actually has a very nice metal case, but the pots are on the board and the plastic stems protrude out of holes. The mod to the case seems doable. Also I would think some rg8 shield used as a braid bolted to the case and going to the K3 might help. I didn't originally do this because a wanted something more portable. I also need to study K9YC's papers since I am not sure the Heil mic is wired to his standards. Thanks, I've got some stuff to try. It looks like a very nice affordable accessory.

[Elecraft] T1: resistance check problems before final assembly
On p. 22 of the T1 assembly manual it states that resistance between D3 anode and the - pad near D7 should be 100Kohms. That's good. However, it then states that when I press S1 I should see resistance between 117k and 130k ohms. I have 148k ohms. Is this a problem? If so, what should I check? I've tried switching the leads of my multimeter, but that doesn't appear to affect anything. Thanks for your help. -john W4PAH __ 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] K3 frequency accuracy versus displayed precision
The K3 is capable of displaying frequencies to 1 Hz. It can be calibrated to somewhat less than 1 Hz against WWV (method 2). Because I wanted to see if my K3 serial 1322 was capable of measuring frequency to its displayed precision, I decided to attempt the November 11/12 ARRL Frequency Measuring Test. I warmed up my K3 for about two hours because--even with the optional TCXO--my K3 drifts almost 0.1 ppm per degree Centigrade from 25C to 30C, the latter part of its warmup range this time of year at my QTH. (0.1 ppm is almost 1 Hz on 40 meters.) Then I carefully used method 2 to calibrate against 10 MHz WWV, checking after exiting REF CAL by tuning across WWV on CW with SPOT activated to see that the beat notes were similar on each side of zero beat for 1 and 2 Hz off frequency. (A lack of similarity indicates that a small tweak of REF CAL is needed.) Tuning past WWV's carrier on CW with SPOT enabled also provides practice for the real thing. When W1AW (and each of the other FMT stations) began its call-up, I tuned its frequency to be centered in the passband with the DSP set at 50 Hz bandwidth. When the long dashes began, I turned on SPOT and zero-beated against the sidetone with 1 Hz fine tuning. After recording the result, I moved on to the other frequencies and stations that had been specified in the ARRL FMT announcement. I was able to copy and measure 4 of the 5 tests, with one station on one frequency being inaudible at my QTH. Result: my K3 was within 1 Hz on all 4 readings, that is, its accuracy matched its displayed precision--after warmup and careful calibration. 73, Paul W8TM __ 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] K3 variable bandwidth roofing filters: any news?
Hi all, I'm considering buying an extra pair of SSB roofing filters (either the 1.8 or the 2.1 kHz) for my K3. I wonder if we can except the variable bandwidth roofing filters to become available any time soon. I haven't seen any talk about it for quite some time now. Does anyone have some info? 73, Frank PA4N __ 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 variable bandwidth roofing filters: any news?
Early next year, I hope, but can't promise a date right now. Things got a bit busy (W2, K3 2-m module, P3, a bunch o' firmware, etc.). tnx Wayne N6KR On Nov 16, 2009, at 10:34 PM, Frank R.

Re: [Elecraft] K3 frequency accuracy versus displayed precision
Hi Paul I find the same thing, I have checked the clubs K3's against a rubidium standard that was calibrated to a cesium standard. The K3 is spot on, the only limitation being its 1hz calibration step limit for the TCXO. I wonder what use the yet to be released external standard interface will be when we can only adjust the TCXO in 1 hz steps. Its amazing how far off frequency most stations are when you use a radio thats dead on, the typical average being 40 to 80hz off. The K3 sounds so good on RX these days, its easy to pick stations that are off frequency by even a few HZ. The radios that I have found to be consistently on frequency are the IC7700 and IC7800. The SSB stations that impress me the most for being on frequency are the different Aeronautical control towers. These control towers have such excellent audio quality and they are always spot on frequency. Its a shame that more ham stations cant sound so professional and clear like these aeronautical SSB stations. I have always wondered what brand of transmitter they use? The excessive bass and ESSB audio that we hear so often just sounds so awful in comparison. Excessive bass and ESSB is just not good audio for SSB use. (I dont want to start a SSB debate!) but ESSB bassy audio sucks in comparison to these commercial SSB stations!
