Re: [Elecraft] SDR-IF and I/Q questions
Ken, Yes, and no, I don't believe NaP3 does logging internally, but adding LP-Bridge to provide virtual serial ports (which emulate the K3 to the application) can allow loggers, CW Skimmer, etc. to connect through a single physical serial port (NaP3 would also connect through LP-Bridge). No difference in that respect than using other SDR applications such as PSDR-IF. 73, Don W3FPR On 11/10/2011 2:48 AM, Ken Chandler wrote: Don et al Don't think it's mentioned on the forum, but does any of the logging software like wintest etc, interconnect freely with naP3 beta!! __ 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] SDR-IF and I/Q questions
Ed,
The I/Q outputs are baseband audio - just as would be the case with the
output of LP-Pan, or a Sofrrock receiver, or most any SDR receiver. The
serial (or USB) port is only used when rig control is introduced in
addition to the panadapter function.

This is the new subject title, and needs some background, so it will
be lengthy this time.
Some of us use SDR-IF, and the new KX3 will use SDR-I/Q methods for
connecting to a computer running SDR software and seeing the results
on a monitor. (The SDR-IF users must provide a SDR-IF receiver to
bring out the I/Q leads. It is to be assumed that the SDR-IF receiver
is functioning correctly.) With both types, I/Q leads are brought
to a computer. (If you are wondering, I am on the list for a KX3)
So the computer AND THE SOFTWARE are the center of attraction here.
This is where great things may happen. (Emphasis on 'may')
Some of us are at different experience levels, but I think we all
would have, and still would, appreciate help to reach
satisfaction. The reflector is the place for this. The real question
is; Should this be on a dedicated thread? When I read the KX3 was
going to be SDR capable, I wondered if Elecraft realized what it was
getting into for the reflector?
IMHO, The weak link in this SDR thing is the computer and software.
PSDR-IF has great control features, but when I compare it to HDSDR,
the latter does a great job of displaying the signals and is very
sensitive. PSDR-IF looks at both directions in spectrum, so far, I
can only get HDSDR to look upward in spectrum.
We can't get rid of the mirrored images in PSDR-IF. ('WE' includes a
friend who still owns 3 of 6 Flex radios he has owned, and 2 of 4
SDR-IF receivers. He is no beginner to SDR.)
My thanks to all who responded. Can't take the space to recap
everything, but Sebastian suggested mirrored images are due to ground
loops. It has been long enough that I can't remember if I checked
that, and I will. However, why just PSDR-IF and not HDSDR that is
affected? A ground loop should affect both. Still, it is worth checking out.
Basically, I'm disappointed with the software. I don't mind
installing and setting some options for my type of equipment, but
from there-on I expect it to function conveniently and nearly as well as a P3.
The question for today is; have any Elecraft users achieved that goal
with a computerized pan-adapter? And if so, with what software? And
if so, do you use a USB to Serial, or straight Serial?
Thanks, from now on it will be shorter.

Re: [Elecraft] K3 Filter question - SSB
Bruce this is from a similar question on the Yahoo Groups K3 list: -- In elecraft...@yahoogroups.com, Hector Padron ad4c2006@... wrote: The 1.8 roofer today with so much band noise and fool ops close to your freq disrespecting the spectrum, its a must.This 8 poles filter together with the DSP makes brick rx easy to work dx or contesting.The trick to recover the lost audio quality when using it is to move counterclockwise the shift control down to 1.2 and inteligibility is back. This is very misleading and I must strongly disagree. I preface this by saying I made ~2500 QSOs on 10m single band in the CQ WW (high-claimed USA SOSB/10 score) and was never able to effectively use the 1.8k filter even though I tried in vain several times. Here's what a 1.8k will and will not do: 1. It *WILL* keep your AGC from pumping if there's another strong station within the 1.8 kHz passband. However, do you really think you could copy a weak signal while a S9+30 interfering signal is inside your 1.8k bandwidth? I don't think so. With any typical SSB filter bandwidth, AGC pumping is not a practical issue (it IS a big deal for CW however). 2. It *WILL *NOT* keep splatter from adjacent signals out of your passband. If an interfering signal is 5 kHz wide and partially falls within your passband, NO filter can remove it. Splatter is a real signal which NO filter (XTAL or DSP) can remove. 3. It *WILL* require very careful tuning for intelligibility. With callers that are off frequency by only 100 Hz, you'll miss off-frequency callers the first time which will slow your run rate. I had one caller even 500 Hz below my run frequency and I'm certain I would never have heard him if I was using the 1.8k. The most effective use of a 1.8k is probably for copying an extremely weak DX signal in white noise (not strong splatter or QRM). By tuning VERY carefully, you may slightly reduce the noise floor by reducing the noise bandwidth (potential reduction of 1.8k BW versus 2.1k BW is 10*[log (1.8/2.1)] = -0.67 dB). I really doubt many of us can detect a 0.67 dB improvement in signal/noise. The 1.8k is mainly a DXing tool...not a contesting tool. It cannot magically overcome the basic laws of physics. 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Filter-question-SSB-tp6981339p6981505.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] Incredible noise tornado on 16om
The RFI that we are seeing is present all day, every day, at a consistent level.

[Elecraft] SDR-IQ and K2
Hi Folks, I have a Z1 buffer board in my K2 and have used it to drive a softrock as a panadapter for some time. It works just fine, but I have left this uncalibrated and my PC doesn't really have enough horsepower to run my external soundcard. I have been trying to reduce PC overhead and introduce click to tune by using an SDR-IQ instead. The system displays OK, but I cannot get Simon's SDR-Radio software to calibrate the panadapter to zero beat the radio RX. I know about the cal functions, but can't dial in enough offset for all modes. I suspect I am doing something fundamentally incorrect - can anyone help? 1) I am using telling the SDR that the IF is 4.915MHz. I assume that is correct? I see that the soft rock radios are at 4.898MHz and I am not sure why. 2) I assume the K2 offsets the frequency when modes are changed? If so, by how much on each mode? Does any mode have no offset at all? This would be the one I need to perform my initial calibration with. If any one has a K2 working with an SDR-IQ (either with SDR-radio or any other software that provides click to tune) I'd really like to hear from you - i have plenty to learn!

Re: [Elecraft] SDR-IF and I/Q questions
Take a look at TRX-Pan, Tony. It does exactly that, is very well integrated with the K3, properly displays both main and sub passbands in all modes (including data sub-modes) and has a very nice uncluttered interface. It is very small code-wise, launches immediately and runs well even on netbooks. It is also very simple to install. It requires either LP-Bridge or TRX-Manager as the serial interface, but most SDR users would need LP-Bridge anyway. LP-Bridge is also small and normally runs in the background. http://www.telepostinc.com/TRXP.html Larry N8LP On 11/10/2011 10:27 AM, elecraft-requ...@mailman.qth.net wrote: Message: 26 Date: Wed, 9 Nov 2011 21:07:38 -0600 From: Tony Estepestept...@gmail.com Subject: Re: [Elecraft] SDR-IF and I/Q questions To:elecraft@mailman.qth.net Message-ID: CACHwrmPUciYL54oJ+sim8r+xjuaqOt9=1gcy3camkn5v74c...@mail.gmail.com Content-Type: text/plain; charset=ISO-8859-1 On Wed, Nov 9, 2011 at 5:51 PM, Don Wilhelmw3...@embarqmail.com wrote: == Somewhere along the line there may be a third kind of SDR software: program that displays a nice panadapter and provides solid CAT control for 2 VFOs, but nothing else.

The most important benefit, however, would be that cutting out the massive code bloat might make it possible for somebody to actually get a handle on the mysterious interdependencies and internal conflicts inside the code that cause bugs: disappearing config files, unexplained shutdowns, loss of functionality, etc. The traditional excuse for these phenomena is to blame the OS, the computer, or the user, but we all know better. The reality is that when you have a huge, open-ended project, with rubbery design specs, with many hands contributing independently, partly object-oriented and partly not, partly written in native code and partly in interpreted code, partly tested and partly not, you are going to have problems. A smaller piece of code with clear design objectives, unity of purpose, unity of design and coding standards, and clearly enunciated testing checkpoints, would be a really cool thing for the next generation of the ham station hardware/software combo. 73, Tony KT0NY __ 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] Silly question about DVK3
Fred, I'm not sure when this feature was added but you can send commands to the radio with the message function keys. Open the CW/RTTY/SSB Memory Setup window and select the Help button. The radio commands are sent when you use %GAxx in the message. The xx refers to a command number you define in writelog.ini. An example will show what I'm doing. I have a CQ message stored in M1 on the K3 and want to send it using F1. My F1 message in WriteLog is %GA11. Now I need to define command #11 in writelog.ini. I added a line to the [Elecraft_K3_commands] section that says: Macro_11=SWT21; You need to start at command number 11 or higher because 0 through 10 are reserved. The SWT21; comes directly from the K3 Programmer's Reference. I have defined five macros in writelog.ini so far, one for each of the M1-M4 buttons and one for the REC button to use as a way to kill a message being sent. So my file looks like this: [Elecraft_K3_commands] Macro_11=SWT21; Macro_12=SWT31; Macro_13=SWT35; Macro_14=SWT39; Macro_19=SWT37; The message for F9 is %GA19 and I reassign the ESC key to send Message 9 to make it work like CW. As others have said the ESC key is a bit of a kludge and could cause problems if it is hit when a message is not playing. But the worst case is you would have to hit it again to reset before hitting another message key. I'm still trying to find a way to used both memory banks but so far no go. 73, Pat K0PC -- View this message in context: http://elecraft.365791.n2.nabble.com/Silly-question-about-DVK3-tp6948894p6982211.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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 Filter question - SSB
I also have a pair of the 1.5 KHz filters, and while I find them to be desirable under certain DXing situations, I rarely use them in a contest. In a contest you need quick intelligibility and filters as narrow as 1.5 KHz don't necessarily give you that. I have a pretty good ear, but lots of human voices have enough energy in different parts of the audio spectrum that I find it sometimes necessary to either shift to a wider filter or change the shift on the 1.5 KHz filter (I typically use 1.1 KHz for the center with that filter) in order to copy the other guy's callsign or exchange. Plus, as W4ZV pointed out, there is so much atrocious splatter from crummy rigs or ignorantly adjusted rigs during a major contest that it is truly rare to find such a narrow filter actually being helpful. I also would trade my 1.5 KHz filters for a pair of 1.8 KHz filters in a heartbeat. 73, Dave AB7E On 11/10/2011 8:27 AM, Joe Subich, W4TV wrote: I would not go any tighter than 1.8 KHz.

Re: [Elecraft] SDR-IQ and K2
Steve, you might want to look at the combo of LPB2 and NaP3. LPB2 allows sharing of the rig port with an SDR and up to 5 apps, like LP-Bridge does with K3. NaP3 is the latest iteration of Flex's open source PowerSDR, has some really neat features. A version of NaP3 is in pre-release which fully supports K2, with extensive support for offsets for all modes.

Re: [Elecraft] SDR-IQ and K2
Steve: 1. 4898 KHz is the nearest to 4915 KHz cheap, off-the-shelf crystal that Tony (developer of Softrock) found. It has the advantage for anyone not using a high isolation buffer amp such as the Z1B, that the local oscillator leakage is outside the K2's crystal filter bandpass. This avoids hearing the Softrock local oscillator as a steady carrier in the K2. 2. Yes, the K2 shifts frequency with mode changes. You can measure your K2's shift by tuning a strong stable signal and working through the modes and observing the shift on the Softrock/software display.

With any typical SSB filter bandwidth, AGC pumping is not a practical issue (it IS a big deal for CW however). Bill, I'm confused by that first sentence. How can a signal within the passband NOT pump the AGC? Normally when AGC pumping is discussed, it's a negative reference to an adjacent signal that's outside of the passband. Barry N1EU You're correct Barry. I meant to say just outside your passband. However, given that most SSB signals generate 3rd garbage (spurs, phase noise, etc) in the area of -35 dBc, an S9+30 signal just outside your 1.8k passband will easily obliterate a weak signal inside the passband. I found my ears to be the best tool for copying weak signals in the presence of strong adjacent splatter. For whatever reason they heard better using the stock 5-pole 2.7k set to a DSP BW of 2.0-2.1k than the 8-pole 1.8k set to actuate at DSP = 1.9k.

Re: [Elecraft] K3 Filter question - SSB
I've had exactly the same experience. If the offending QRM is outside the passband of the filter, the narrower filter setting helps. However, If the offending QRM is heavily inside the passband (i.e., splatter), it seems that the additional intelligibility gain by capturing more of the desired station's audio bandwidth can often more than offset the additional interference you get from using a wider bandwidth.

Re: [Elecraft] K3 Filter question - SSB
I'm glad this came up because it is an aspect of filtering that seldom is addressed. Many folks seem to think that you can arbitrarily close down the bandwidth of a receiver to eliminate QRM and improve intelligibility. 1.8 kHz is deemed better than 2.1 kHz, and 1.5 kHz is deemed better than both. But at some point intelligibility itself suffers because you start to eliminate the signal you're trying to copy in the first place. I for one suffer from a type of listener's fatigue when forced to copy SSB signals in anything less than about 2.2 kHz or so. Others folks suffer from hearing loss and need to hear as much of the voice frequencies as possible. 1.8 kHz just doesn't work for many of these folks. If you're okay with such narrow bandwidths, more power to you, but you can't make blanket statements about them being equally effective for everybody. As Bill, Dave, and Barry alluded to, the ear-brain filter is the most effective of all, and it would do us all good to exercise it more often. The more you use it, the better you get at it.

Re: [Elecraft] K3 Filter question - SSB
Interesting to me is position today that 2.1 kHz is narrow. For many decades, a 2.1 kHz filter was normal, and sometimes only SSB filter. Heathkit SB-101 etc 350 - 2450 (center 1400) Collins KWM-2A etc 400 - 2500 (center 1450) Sometime during the 90s, or so, the standard seemed to move to 2.4 kHz and up. What happened? Because of my early experiences with a SB-101, I decided that the Heath SSB BW settings were for me. Therefore I have a 2.1 kHz roofing filter installed and set the BW to 350 - 2450 and stored into NORM1. Which leads into a K3 issue. I believe that it would be a service to all of us users if the K3 manual had a set of optimal center frequencies for some of the pseudo standard settings optimized by those before us at Heathkit, Collins, and others. And it would be nice if the NORM button was programmable. I understand that there are the NORM1 and NORM2 settings, but for me, simple NORM is a wasted SSB button as I never use a 100 - 2900 Hz BW. And it would be nice if there was a default SSB center for each of the filters in Filter configuration. Tapping XFIL would not only move to the next filter, but also set to it's optimal SSB filter center frequency.

Re: [Elecraft] SDR-IF and I/Q questions
Ed, The SDR-IQ apparently uses the USB connection for both audio stream and rig control, but the KX3 does not. The I/Q output of the KX3 is baseband audio, which would need to be fed to a soundcard. The rig control is separate and will communicate with the KX3 through the RS-232 serial connection, so if you don't have a real serial port, you will need a USB to serial adapter to achieve that connection. BTW - there seems to be nothing universal about the Universal Serial Bus - each device version seems to be different requiring its own driver. OTOH, the basic RS-232 port has always been universal - it just works because there are no bells and whistles (but that is getting a bit off-topic, thanks for listening to my rant). 73, Don W3FPR On 11/10/2011 5:28 PM, Edward R.

[Elecraft] K3 Filter question - SSB
Just my (unsolicted) two-cents comment: I find using below 2.1 KHz (with the DSP filter) distorts SSB too much for me. I have only the 2.8 and 0.400 KHz filters at this time. If I were to buy another it would be 2.1. Folks should factor in that I am 67 and have extreme hearing loss so your experience my vary (I have to use captioning on TV). (hint) Before purchasing a roofing filter check out using the DSP filter to decide which bw is best for you. I am only a casual user of HF so intense high-density contesting or DXing is not my forte. Operating a little in FD gives me enough of a taste and the K3 is a real joy to use under tough conditions. Mostly, I am copying extreme-weak signals (VHF+) where narrowing bw makes the difference (typ 2.1 for SSB and 100-200 Hz for CW). But I start at 2.8-KHz when searching for weak CW, then switch to 400-Hz filter and use the DSP filter to improve readability (signals below noise) once I found a signal. -- Message: 43 Date: Thu, 10 Nov 2011 10:27:05 -0500 From: Joe Subich, W4TV li...@subich.com Subject: Re: [Elecraft] K3 Filter question - SSB To: elecraft@mailman.qth.net Message-ID: 4ebbed49.4030...@subich.com Content-Type: text/plain; charset=ISO-8859-1; format=flowed I would not go any tighter than 1.8 KHz.

Re: [Elecraft] SDR-IF and I/Q questions
Ed, Don's comments about a serial port being unnecessary was with respect to the KX3 specifically, not the SDR-IQ. The KX3 will provide baseband audio output, which will need to be fed into the stereo input of a soundcard on a computer for panadapter capability. Think of it as having an LP-Pan built in. If one wants point and shoot functions from the panadapter software, then a USB/serial control port back to the KX3 will be needed. And yes, the KX3 will have that capability as it has already been announced that the KX3 will use a subset of the K3 command structure. (there is a serial port on the KX3). Also, a USB interface device for the KX3 is also in the plans from Elecraft. It will connect to a USB port on the computer, and have the required connector on the other end to plug directly into the radio. I hope this helps clear up any possible confusion. 73, Bruce, N1RX (original message) Don, Not trying to be argumentative, but... The SDR-IQ uses a USB-2.0 interface and not audio.

Others folks suffer from hearing loss and need to hear as much of the voice frequencies as possible. 1.8 kHz just doesn't work for many of these folks. Here's some more individual data. Although my hearing cuts off sharply at about 2.5kHz, I love the 1.8kHz crystal filter for heavy QRM. That Inrad filter was originally purchased for the 'narrow SSB' slot of my old FT-1000MP, and I'm so glad that I kept it for the K3. The 1.8kHz filter also works very well for my wife and other guest operators who don't have hearing loss. In our typical contest QRM conditions (running W/VE with the whole of Continental Europe right behind us) the narrower filter helps to eliminate the high-pitched splatter which we find the most tiring. Unlike a 1.8kHz DSP filter with a 2.5kHz roofing filter, the 1.8kHz crystal filter also avoids artefacts caused by pumping of the hardware AGC loop by strong signals in the gaps between the wider and the narrower passband. The 1.8kHz filter does require careful initial setting of the center frequency to obtain the best possible intelligibility; but those settings will then require very little further adjustment. In other words, they make a very effective working compromise to maximize the QSO rate. The 1.8kHz crystal filter is switched in at a DSP setting of 1.9kHz to avoid excessive narrowing of the passband. I would certainly agree that 1.5kHz is too narrow, because almost every voice would then require its own critical tuning. If you're okay with such narrow bandwidths, more power to you, but you can't make blanket statements about them being equally effective for everybody. But neither can anyone else make blanket statements about them being INeffective. The fairest that anyone can say is, If you don't like the 1.8kHz DSP setting, then don't even think about buying the crystal filter. But if you do like 1.8kHz DSP, you might like the crystal filter a lot. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek __ 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

Yes, it is pretty normal, because the mic in the CM500 is a pretty hot mic (that is, high output). By all means, follow the standard setup instructions in the manual. One thing you MIGHT want to change is TXEQ. For virtually all voices, the two lowest bands should be down all the way, and for most voices, the third band should be down between 6dB and all the way. The rest of the bands should usually be set flat, except that those with very muddy voices may want to boost the top band 3-6 dB. I usually run compression so that I consistently see about 10dB compression on peaks (on the K3 display). The best way to get a final setting on TXEQ, mic gain, and compression, is to have someone listen to you on a K3 with their IF bandwidth set to at least 2.7 kHz.

[Elecraft] CocoaModem
Trying to get RTTY/PSK set up and having a hard time with CocoaModem. The K3 line out is NOR 10. Increasing it doesn't seem to do anything. I'm using an iMic. I've selected that in CM, and the volume is set about 3/4 full scale. I've tried the iMic set to both line and mic, no difference. CM is printing garbage. The tuning aid/waterfall show nothing. No transmit. Anybody see anything I need to change or set? 73, Mike NF4L __ 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] Click or Pop Sound Using Diversity Receive
I am using diversity receive on CW and notice a pop or click (sounds like a relay ) after sending a word (semi bk-in ). This does not occur with the AUX ANT disengaged as I am no longer using the second antenna. My rig is set up to use the second receiver antenna attached to ant port #2 instead of the BNC arrangement for AUX receive. When I bought this rig used it was set up that way. I wonder if this may have something to do with it? Any ideas?

Re: [Elecraft] CocoaModem
Hi Rick - I think so. The output and input tabs have the slider almost full scale. The Use audio port for is set to output on the output tab and on the input tab it's set to input. I'm running Lion.

[Elecraft] [OT] The Big List
Well, I started following this list in October 2009. Bought my K3 at the end of December 2009 and go through all the messages (albeit some quite quickly) almost every day. I decided to archive all my messages that I keep in my Elecraft mail folder and I was surprised to see that I was archiving over 38,000 messages! Now, the actual message count is more then that since I have deleted some, and I don't know how many, but still that is a lot of messages. 73, phil, K7PEH __ 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] SDR-IF and I/Q questions
was hoping that the KX3 may end up as a kinda Flex Lite with access via a program or as a portable field unit Ohhh its so good !

The I/Q output of the KX3 is baseband audio, which would need to be fed to a soundcard. The rig control is separate and will communicate with the KX3 through the RS-232 serial connection, so if you don't have a real serial port, you will need a USB to serial adapter to achieve that connection. BTW - there seems to be nothing universal about the Universal Serial Bus - each device version seems to be different requiring its own driver. OTOH, the basic RS-232 port has always been universal - it just works because there are no bells and whistles (but that is getting a bit off-topic, thanks for listening to my rant). 73, Don W3FPR On 11/10/2011 5:28 PM, Edward R. Cole wrote: Don, Not trying to be argumentative, but... The SDR-IQ uses a USB-2.0 interface and not audio. Some SDR actually provide A/D conversion inside the box with digital output streams. The units you mentioned are audio-baseband. The only issue would whether one needed a good soundcard or not. I understand that many sw provide for radio control so need that access (whether via USB or RS232). K3 being one of those that offer external control. I wonder if the KX3 will have that ability, as well? Very handy for the click frequency operations on sw like psk-31 (variants). The eme SDR sw (Linrad) that I am using has this ability (if proper drivers are available for the radio). __ 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 New #34;Skinny#34; Fruit How This Strange 62-Cent African Fruit Is Making Americans Skinny. http://thirdpartyoffers.juno.com/TGL3141/4ebc89e999482767afm03vuc __ 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
