Re: [Elecraft] KRX3 AUX Ant
Well I just placed the order for the SubRX today so I should be getting that cable in the box. Here's hoping that all goes well with the install as I won't have much time to get replacement parts from Elecraft before FD if there are any issues.

This is actually a good idea for anyone considering later adding the KRX3 when first building your initial K3. It's much easier to install and route the AUX RF connector and cable initially, even if you don't install the KRX3. I believe the only caution is to secure the TMP connector so that the shield cannot touch any active components. I taped my TMP cable to the outer sheet metal enclosure for the KPA3. I don't recall the part number for the AUX RF TMP cable assembly normally supplied with the KRX3 but Elecraft will know what you mean if you place an order for one with your initial K3 order. 73, Bill __ 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 Overload from WYFR
Hi Lyle, You might try adding an attenuator between the K3 IF out and the LP-PAN IF in and see if the overloading disappears. If so, it might indicate the LP-PAN system is overloading rather than the K3. 73, Lyle KK7P PS - The K3 blocking dynamic range is 20 to 30 dB better than PC-based SDRs. So I suspect you are seeing a weakness in the PC-based SDR system rather than the K3, but I've been wrong before! :-) I'll probably have to eat Humble Pie, but with respect I don't believe that Steve has an overload problem, but could have a spurious mixing problem, the result being similar to intermodulation. Also, the problem might or might not be caused by the K3 nor LP-PAN, which would not be difficult to determine if another receiver is available. The screen capture of WYFR's carrier at 6985 kHz, and a family of products, shows that the spacing product to adjacent product is roughly 4.64 kHz if the low level intermediate products are ignored, which they can be in this exercise. If these products are the result of mixing (or are IMD products), there has to be of course another signal spaced 4.64 kHz from WYFR's carrier - and there is one at 6980.36 kHz, whose amplitude fits the amplitude pattern of the products. Of course, the device or transmitter generating this signal at 6980.36 kHz might in fact be operating at a sub-harmonic frequency e.g. a MF BC station, and the rogue mixer itself is generating the 6980.36 kHz harmonic. 73, Geoff GM4ESD __ 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] new address
Sheldon, and others using Google's gmail. There's a semi-obscure, but rather cool feature in gmail that lets you create an unlimited number alternate e-mail addresses in the fly. All you do, when providing your gmail address, is to add + and then additional characters to your existing address. From there, you can manage incoming message with filters to automatically route the different incoming messages (or even automatically delete them). Example: Joe Ham signs up for a gmail account, and selects wx1xxx.joe_...@gmail.com as his new address. Joe Ham then goes to some random website, which is asking for his e-mail address. Joe can give them wx1xxx.joe_ham+random_webs...@gmail.comwx1xxx.joe_ham%2brandom_webs...@gmail.com, and any e-mail from there will come to his wx1xxx.joe_...@gmail.com account, but with the address wx1xxx.joe_...@gmail.com. Then, he visits another website, and gives THEM the address wx1xxx.joe_ham+random_websi...@gmail.comwx1xxx.joe_ham%2brandom_websi...@gmail.com. If he gets too many e-mails addressed to wx1...@joe_ham+random_website2, he can create a filter to automatically delete any incoming mail addressed to that address. Of course, spammers might be hip to this, too, and understand that they can remove the + and everything after it, and have a good address...but, still...it might be useful. 73, Steve NN4X On Tue, Jun 16, 2009 at 1:03 AM, Sheldon Howard sheldonhow...@gmail.comwrote: Due to the large amount of spam received at this email address, ( sheldonhow...@gmail.com) I will discontinue using this address immediately.

Re: [Elecraft] K-2 Blue Display
The K2 display is a soldered-in LCD that sits over a (soldered in) diffuser that is illuminated by LEDs incorporated into the diffuser. To change colour, it would be neccessary to desolder both. That's a tall order for a frail LCD display if you don't have the necessary skills and equipment. Alternatively, the display could be sacrificed and replaced with a new one as the removal of individual pins is an easier task than removing around 40 of them, all attached to glass. Whether or not the diffuser is available in different background colours is another question. Some time ago, I refurbished a Yaesu Rx where one of the jobs was to replace all the LCD illumination bulbs that, barring one, had blown. After removing the pea bulbs AND their sleeves, I decided to use LEDs instead. Amber, green, blue and white were tried, but all looked pretty awful to me. Eventually, I located a green-blue LED that closely matched the original colour, and they looked just fine. It made me wonder whether LCDs are manufactured to suit a particular colour of illumination.

[Elecraft] TX EQ setting
I have identified an easy way to switch between various TX EQ settings
using N1MM or Logger32 thanks to information kindly supplied by Bill
Coleman N2BC, author of K3_EZ.
The method involves using the macro functions in each program to set
compression and TX EQ bands. For example, flat with no compression in
Logger32 would be
$command cp000;mn008;swt53;mn255;$
which zeroes compression, clears the existing EQ and tidily terminates.
For my DX/Contest setting I use (the space after 'command' may appear as
a line feed):
$command
cp025;mn008;swt53;swt11;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;swt12;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;swt13;dn;dn;dn;dn;dn;dn;dn;dn;dn;swt24;dn;dn;dn;dn;mn255;$
which sets CMP to 25, clears the existing EQ and then sets it to -16,
-16, -9, -4 in the first four bands and then exits gracefully.
The N1MM macros need starting with {CAT1ASC instead of $command, then
terminating with } instead of $.
Other EQ settings can be easily set by examining the K3 Programmers
Reference; a macro that needs very many commands may exceed the maximum
length which is 255 in N1MM, unknown for Logger32.
Although the Programmers Reference suggests that successive SWTxxx
commands may need 100msec delay to 'set', these macros work with the COM
port at 38400 without any apparent need for command pacing.

PS I have just read Wayne's mail about keeping EQ settings within ±6dB
so I am about to change the macros after writing this. Perhaps Wayne

Re: [Elecraft] TX EQ setting
I think the logger EQ macros are probably most useful where a station is switching modes often and needs to tailor the response appropriately. Logger32 has up to 36 macros available so there is plenty of room for them in there. N1MM appears to have less space and as you rightly point out, disrupting the more useful N1MM macros is undesirable. In a serious contest situation the EQ would be set up before the start to avoid this problem. Running an independent macro program through the COM port can be problematical if the logger is also using that port; K3_EZ or the Elecraft Utility cannot be used with a logger through LP-Bridge or there would be no problem. Yes, I can unload the logger, load up a macro program, run the macro, reload the Logger, get my spots back in place and find where I was but it is not elegant :-) 73 Pete w...@comcast.net wrote: There are macro programs that can run outside these applications can can take any key sequence and make these changes.

Re: [Elecraft] K3 Feature Request
Thanks Bill. Under the 10Hz steps on the K3, I think the 1Hz digit is zeroed as soon as the tuning knob is turned. You can check this by tuning to something other than X.XX0, tapping the fine button, turning the knob and taping the fine button again. Someone close to Elecraft may have a better understanding. I like the 10Hz tuning rate per knob angular rotation. I'm usually tuning for kHz.000, sometimes kHz.500. I like the speed/feel of the 10Hz tuning speed. I find it quick and efficient to tune ~10Hz below the kHz.000 frequency which causes the 1kHz, 100Hz and 10Hz digits to change to X(-1).99 , or as I am suggesting X.9. Then it is a very slight motion clockwise to get to X.0kHz. An example... I am primarily an SSB operator. It seems most SSB stations operate on kHz.000 frequencies. The 'display' resolution of 10Hz isn't usually needed, though I do like the angular knob speed of 10Hz. When tuning for say, 7.155.000, I watch the the .0 (hundreds) digit closely. If tuning down from a higher frequency and getting close, and I see 7.154.9, I make a slight turn clockwise and I'm precisely where I want to be. When I'm close, the 100Hz digit is the one I'm watching. The displayed 10Hz digit is distraction when changing at 10X the speed of the digit I am most concerned about. Watching the 100Hz digit is less tedious than watching the 100Hz digit and the 10hz digit simultaneously. While what you suggest with the 100Hz digit accomplishes the same effect per the display, I like the angular rate of the knob as well as the near analog sound when tuning across the band with the 10Hz rate in effect. Having the 10Hz digit tuning might be useful for some fine tuning of stations slightly off of kHz.000. It may or may not be important for that to be displayed depending on circumstances. Some older radios featured only a 100Hz digit but tuned in 10Hz steps.

growing popularity of the K3.

Sorry, that should be mn009; for TX EQ - mn008; is of course RX EQ.
Can't see a way of doing it in Win-Test, Nick. One of the reasons why I
abandoned my (paid for) Win-Test in favour of N1MM.
Peter Connors wrote:
I have identified an easy way to switch between various TX EQ settings
using N1MM or Logger32 thanks to information kindly supplied by Bill
Coleman N2BC, author of K3_EZ.
The method involves using the macro functions in each program to set
compression and TX EQ bands. For example, flat with no compression in
Logger32 would be
$command cp000;mn008;swt53;mn255;$
which zeroes compression, clears the existing EQ and tidily terminates.
For my DX/Contest setting I use (the space after 'command' may appear as
a line feed):
$command
cp025;mn008;swt53;swt11;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;swt12;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;swt13;dn;dn;dn;dn;dn;dn;dn;dn;dn;swt24;dn;dn;dn;dn;mn255;$
which sets CMP to 25, clears the existing EQ and then sets it to -16,
-16, -9, -4 in the first four bands and then exits gracefully.
The N1MM macros need starting with {CAT1ASC instead of $command, then
terminating with } instead of $.
Other EQ settings can be easily set by examining the K3 Programmers
Reference; a macro that needs very many commands may exceed the maximum
length which is 255 in N1MM, unknown for Logger32.
Although the Programmers Reference suggests that successive SWTxxx
commands may need 100msec delay to 'set', these macros work with the COM
port at 38400 without any apparent need for command pacing.
73, Pete Connors F5VNB/G4PLZ
PS I have just read Wayne's mail about keeping EQ settings within ±6dB
so I am about to change the macros after writing this. Perhaps Wayne
will reduce the limits in future firmware?

Re: [Elecraft] new address
FYI, this should work with any decent email program or service;it's been around for years. I used it for a bit in 1998. George(N3YSA) -original message- Subject: Re: [Elecraft] new address From: S Sacco nn4x.st...@gmail.com Date: 06/16/2009 7:50 AM Sheldon, and others using Google's gmail. There's a semi-obscure, but rather cool feature in gmail that lets you create an unlimited number alternate e-mail addresses in the fly. All you do, when providing your gmail address, is to add + and then additional characters to your existing address. From there, you can manage incoming message with filters to automatically route the different incoming messages (or even automatically delete them). Example: Joe Ham signs up for a gmail account, and selects wx1xxx.joe_...@gmail.com as his new address. Joe Ham then goes to some random website, which is asking for his e-mail address. Joe can give them wx1xxx.joe_ham+random_webs...@gmail.comwx1xxx.joe_ham%2brandom_webs...@gmail.com, and any e-mail from there will come to his wx1xxx.joe_...@gmail.com account, but with the address wx1xxx.joe_...@gmail.com. Then, he visits another website, and gives THEM the address wx1xxx.joe_ham+random_websi...@gmail.comwx1xxx.joe_ham%2brandom_websi...@gmail.com. If he gets too many e-mails addressed to wx1...@joe_ham+random_website2, he can create a filter to automatically delete any incoming mail addressed to that address. Of course, spammers might be hip to this, too, and understand that they can remove the + and everything after it, and have a good address...but, still...it might be useful. 73, Steve NN4X On Tue, Jun 16, 2009 at 1:03 AM, Sheldon Howard sheldonhow...@gmail.comwrote: Due to the large amount of spam received at this email address, ( sheldonhow...@gmail.com) I will discontinue using this address immediately.

Re: [Elecraft] K-2 Blue Display
I have a 1964 vintage Drake R4A which suffered from faded blue gel filters. I tried blue LED lamps as sold by a Stateside amateur. While they worked well and as advertised, the intense blue of the LEDs was very distracting... I eventually went back to filament lamps with a new set of gel filters. My PC has a blue LED that lights up the shack, again that colour isn't pleasing to my eye at least. I guess what I am suggesting is that some of the modern blue LEDs can be awful to look at, while I like the older blue displays, I personally wouldn't expend any time or money changing the K2 illumination to blue. 73 Dave, G4AON K1, K2 and K3 owner I would be interested in converting the display in my K-2 to the now popular blue display available in many radios, including the vintage Drake line as well as some of the modern transceivers. Anyone try this yet? Where did you find the parts? Many thanks, and I enjoy reading the helpful posts on the Reflector.

[Elecraft] K3 vs. Icom IC-7600
Yeah...at what spacing? From the ARRL pages, for the IC7800 (I don't think anyone is saying teh 7600 is better than the 7800, but I could be wrong) At 2kc, 3rd order dynamic range for 7800 =86 db; for the K3=103db At 2kc, 3rd order intercept for 7800 = 21 dbm; for the K3=28dbm At 20kc spacing, things may change (I didn't bother to look), but who cares...if the band is dead (few signals), these numbers won't matter anyway. If the band is hopping (crowded), 20kc spacking specs are meaningless (to me)it's the nearby signals that will get your front end. de Doug KR2Q __ 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

The 3 kHz BW filter Eric refers to above has actually been measured at 5.2 kHz by Sherwood (assuming it's the same one used in the IC-7800). The following is a direct quote from Sherwood regarding the 7800's 3 kHz and 6 kHz (actually measured 11 kHz) filters below: The 3 kHz (5.2 kHz in my radio) roofing filter had a couple dB more IMD than the 6 kHz (11 kHz) filter. Source: http://groups.yahoo.com/group/ic7800/message/5417 I do not believe any Icom advertising...which is what Universal Radio's comments are based on. If you wait for ARRL, RSGB (already published?) or Sherwood tests of the 7600, my guess is its close-spaced IMD performance will be about 20-25 dB worse than the K3. Remember the advertising claims for the Ultimate Transceiver (the IC-7800)? Look where it falls in close-spaced IMD performance on Sherwood's site (80 dB is actually identical to a little K2...and $10,000 less expensive!) Regarding the anonymous RFEXPERT...this self-proclaimed expert reaches different conclusions about the K3 compared to genuine RF experts like W8JI and ON4UN (both now K3 users).

Re: [Elecraft] K3 vs. Icom IC-7600
Because an RS232 port is much more nearly universal. Because it's pretty easy to add USB support to a serial port and a problem to add serial support to a USB port. And, if you really want a USB port with sound card included, design one, or get one of the several vendors of standalone boxes that do that to design one for the K3 to replace the IO panel of the K3. Because with built-in USB support gets more complicated. We were talking about this at the NCCC meeting last night, in fact.

Re: [Elecraft] K3 vs. Icom IC-7600
can't understand why the K3 didn't come with a USB port instead of the outdated com port. I can't speak on behalf of Elecraft but for the majority of us, it's a simple matter to convert from serial to USB and more difficult to convert in the opposite direction. USB ports are not nearly as mechanically secure as the DB-9 connector. An accidental strike of the USB plug in the lateral direction can easily cause damage the mating USB socket inside the rig (like a K3 used portable). I've broken a couple USB ports on my laptop PCs as a result of inadvertent strikes. Myself, I would like to see the beginnings of an optical S/PDIF standard that incorporates audio + data/rig control.

Re: [Elecraft] K3 vs. Icom IC-7600
Physical properties aside, USB's advantage is speed. We are running the K3's serial port at 38kb while USB can run 400,000kbJust a tad faster and that allows audio and video transfer. True, USB jacks are flimbsey little things, if it were mounted on an option board like the current RS232 is, it could be replaced without a lot of hassle. Sooner or later, ham rigs will either be the only thing around with RS232 or they will change over to USB like the rest of the world.

[Elecraft] [K3] Roofing Filters
Greetings, One more question on roofing filters, specifically about using identical BW filters in adjacent slots. Lots of roofing filter blurbs on the reflector, but I could not find anything specific to this question. In reading the owners manual, it states that roofing filters are to be placed in decreasing BW order, starting from slot #1, with the option of bypassing slots along the way, with the filter configuration setup taking care of letting the firmware know who is where and for what purpose. The manual also indicates that the firmware relates the DSP BW to the filter setup, and routes the IF to (only) one of the five roofing filter slots, depending on the aforementioned filter configuration/setup. So here's my question. Is it possible, albeit perhaps not terribly beneficial at first glance, to put another 0.40 roofer in the next downstream slot from my current 0.40 roofer? Would the F/W even accept that setup? If it would allow that configuration, would the F/W just select the first 0.40 slot, or would the F/W route the IF through both 0.40 roofers? So the real question is whether there is a way to configure two identical 8 pole roofers (i.e. 0.40 kHz) such that the F/W treats that as 16 poles? I'm guessing the answer is most likely a definite no, per hardware and firmware design, but the remote possibility seemed intriguing nonetheless. I guess this is what happens sometimes when there aren't enough sunspots to keep one productively engaged in this hobby. But hey, if you don't ask, you don't learn. ;-) Thanks. 73 Walter WB2IDK __ 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] K-2 Blue Display
Personally, I'd not want to change the amber color of the LCD in either of my rigs. I feel there's an excellent reason for that. Blue light provides the greatest visual acuity. That's why sunlight, which is very blue, is so good for detail work and why my work table lights are 5800K (sunlight color temperature). That makes it good for situations where we want data at a glance but don't look at the display very long. OTOH, light with a lot of blue is very tiring over time. Red light provides the least visual acuity. Our eyes simply don't see detail well at that part of the spectrum. It's also the color light that is the most relaxing (which is why candle light and fire light is desired for romance). Amber seems to me an excellent compromise: easy to see the characters but not nearly so stressful over time as colors nearer the blue end of the spectrum. If I were to consider some activity that had me in front of my rig for long hours at a time, such as contesting, I'd definitely avoid blue. Even as a casual operator, I appreciate the soft glow of the amber display. Ron AC7AC -Original Message- I understand the desire to have a blue backlight for any LCD.

[Elecraft] K3 transmit and receive audio response
Hello everyone,
I had a chance at Dayton this year to chat with the Elecraft honchos,
and had every one of my K3 questions answered. Thanks, gentlemen.
Meanwhile, a few hours ago, Wayne had written:
{While I'm on this topic, I'd also like to suggest using a minimum of
both RX and TX EQ. The '0' levels were carefully determined
empirically, and in most cases the optimal values will be well below
the maximum range provided. Unless you have an aural sensitivity issue
in some pitch range, or a serious mic deficiency, I'd stay between +/-
6 dB. As with filter gain settings, excessive values can result in
adverse interaction with the DSP.}
What I would like to know is just what the ACTUAL response curves of
the K3 transmit and receive audio are (when all EQ settings are set to
'0', since Wayne stated: The '0' levels were carefully determined
empirically. It would appear from this statement that setting the
EQ's to '0' wouldn't necessarily result in a 'flat' response.
I design parameters for some broadcast audio processors (Omnia's)
and just am curious (and picky) what 'flat' actually is when the EQ's
in the K3 are all set to '0'. And, for transmit, is the internal RF
speech processor applied pre or post of the frequency response
shaping circuitry?
Thanks 73.

Re: [Elecraft] K3 transmit and receive audio response
What I would like to know is just what the ACTUAL response curves of the K3 transmit and receive audio are (when all EQ settings are set to '0', Flat means the EQ does not add or subtract to the filter response dialed in by the operator with the SHIFT/WIDTH/HIGH CUT/LOW CUT controls. The high end and low end response will be dictated by those settings, This will be modified by the impedances in the path from the radio to the headphones or speaker and the impedance of the headphones or speaker, or the characteristics of the transformers and the overall impedances in the LINE OUT case. Finally, the edges of the selected passband will be rolled off by the action of the FIR filter windowing function applied to the filter coefficients. 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

Re: [Elecraft] [K3] Roofing Filters
I'm not the definitive source for the answer to this question, but I'll hazard an educated guess. The firmware probably wouldn't mind if you put two identical width filters in adjacent slots. The firmware would pick one or the other as you dialed the bandwidth to the appropriate values. I don't know which one it would choose. You could lie to the configuration tool and say one of the filters was 450 Hz and the other 400 Hz and be able to use one and then the other at those bandwidth settings. I don't think you'll find a way to run the output of one filter into the other. For any given bandwidth the firmware chooses one of up to five filters; there's no provision for routing the output of one filter into the input of another, and making them the same width wouldn't change that. I'll guess that 5 poles is often enough, 8 poles is almost always plenty and the benefit gained by going from 8 to 16 poles wouldn't often be very important.

Re: [Elecraft] K3 vs. Icom IC-7600
First let me say that I once owned and Icom IC-211. It was such a POS (using solder bridges between IC pins instead of circuit traces for example) that I gave it to a friend who also had one. I often said that it was a measure of his character that he accepted the gift and we still remained friends. So I am no friend of, or apologist for Icom. That said, why would the second mixer in the Icom be any more susceptible to overload than the second mixer in the K3? (Disregard the other evidence that the Icom 3 KHz filter isn't really 3 KHz.)

[Elecraft] KX1 High Power -SOLVED-
My query is answered. I found the answer buried on page 72 of the current KX1 manual. It states Maximum power output from the final stage (Q6) is about 4 to 5 watts, depending on the supply voltage.Q7, in the receive band-pass filter, limits the signal voltage that can reach the receive mixer when the rig is in transmit mode. There is my 5W, it is OK, and I am good to go. This KX1 has a very sensitive receiver and a strong transmitter... I'm going to like it. 73, Ed - AD7GR K2/100 #6050 KX1 #2219 __ 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 vs. Icom IC-7600
Hi Wes, The difference is that we can go to as low as 200 Hz for our first IF filter ahead of the 2nd mixer, limiting what it sees for strong off frequency signals. The 7600 can only get down to 3 kHz (measured by Sherwood closer to 5 kHz) before its 2nd mixer, which is as wide as a barn door with respect to interfering signals. The closer to the front end of a radio you can get your narrowest filter, the better your overall strong signal dynamic range. 73, Eric WA6HHQ Elecraft Wes Stewart wrote: First let me say that I once owned and Icom IC-211.

Re: [Elecraft] K3 vs. Icom IC-7600
can't understand why the K3 didn't come with a USB port instead of the outdated com port. You don't want a USB port if you want to do anything circuit wise external to the K3 using CTS/DTR leads not used for serial signal. If the ONLY thing you EVER want to do with the serial port is talk to your PC, then USB will work. If the Elecraft guys want to do something serious and high speed, then let them use the Ethernet jack. I'd like to see an ethernet interface module option so I can directly remote to it from a computer. Or an 811g wireless module for the same purpose. 73, Guy. __ 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 vs. Icom IC-7600
Hello all, Two weeks ago, in my friend's shack I compared K3,IC7700,IC7800(by ear ONLY), since there are no major contest in that day, so I can't say anything about dynamic range or something like that. IMHO, ic7700's DSP is best, 7800 DSP also better than K3. [A/B compare NR NB and DSP filter function]. K3 need to change in K4(my opinion): 1, 13.8V connector, after mine thaw during the 2008 cqww contest, I have replaced it with connector was use in Motorola transmitter. 2, Shield design. 3, DSP function improvement. 4, true FSK control use RS232 port(not ACC port). By the way, overall I like the K3 very much.

Re: [Elecraft] K3 vs. Icom IC-7600
Hi Steve, The audio from the rig is analog. I have just said there is one connection to the computer but sure there are several lines going from Microkeyer to the Radio (sound, ptt,cw,cat). Still there are other advantages like the ability to create Y connection to the CAT of the trx similar to LP-bridge. 73, Igor UA9CDC - Original Message - From: Steve Ellington n...@carolina.rr.com To: Igor Sokolov ua9...@gmail.com; elecraft@mailman.qth.net Sent: Wednesday, June 17, 2009 12:26 AM Subject: Re: [Elecraft] K3 vs. Icom IC-7600 Errr...How do U get the audio from the rig to that microhammicrokeyertwo Igor om?
