[Elecraft] WANTED - P3 Panadaptor
G’day I am interested in purchasing an Elecraft P3, in very good condition. It would be nice if it came with a modulation monitor, SVGA and associated cables but is not vital. Apparently only a few P3 were sold in Australia. After searching here for a year or so, I am taking my search global. For those in the US, note I have a US address to which the P3 can be sent! Payment can be done via PayPal or direct transfer. You can check me out at qrz.com. Thank you!

[Elecraft] KPA 1500 and Pure Signal - a DDC/DUC SDR in the Elecraft pipeline?
G’day I am sure I am not the only one who has noticed that the new KPA 1500 has a connector on its rear panel labelled ‘TX Sample’. Reading the Elecraft FAQ on the KPA 1500, it says that this “provides a low level KPA 1500 TX RF signal for sampling use by transceivers that support closed-loop pre-distortion techniques, e.g. Pure Signal. This low-level signal is taken directly from the amplifier’s directional coupler.” For those on this reflector who are not familiar with ‘Pure Signal’, it is the name given to “the theory and implementation of the clean transmission logic developed by the OpenHPSDR team and implemented in PowerSDR [softwar as used with the ANAN radios” (see SDR-Radio.com - http://sdr-radio.com/Version-3/Transmit/Pure-Signal). Using pre-distortion, Pure Signal means that transmit IM3 can be improved significantly – up to 20dB from memory. Now Pure Signal is an SDR technique and many amateurs have been wondering when Elecraft is going to finally take a leap beyond the KX3 into digital down conversion/up conversion SDR or even the latest Direct Fourier Conversion SDR? Looks to me perhaps that the leap is not far off – unless Elecraft are seeing a big market for ANAN SDR owners buying the KPA 1500 (which, incidentally looks fabulous)? ;-) What say you, Wayne N6KR?

Re: [Elecraft] A question about using the K3S with KPA500 on fullbreak-in
Hi Fred Thank you so much for the information and the K-line intro_guide PDF – very much appreciated! It looks like the key to the situation is connecting the ACC connector from the K3S to the KPA500 and, once this is done, the KPA500 will follow the K3S settings, i.e. if the K3S is set to full-break in, the KPA500 will follow this.

[Elecraft] K3 AGC settings used in CQ WW CW
G'day Prior to the CQ WW CW contest, I did some experimentation with the K3 AGC settings (rev 4.51 firmware). I started with the AGC SLP set to 0 and the AGC THR to 8. After some problems with the AGC action on stronger signals (S9 to S9 plus), I increased the SLP to 2 and found that there was no longer any need to turn the AGC off and ride the RF gain on these signals. These settings worked well for me here in Western Australia, but the signal levels aren't as high as they would be in Europe or North America.

[Elecraft] Rev 4.51 firmware - what AGC settings worked on big pile-ups with loud AND weak signals in the WPX?
G'day Unfortunately my tower has been down for a couple of weeks now owing to a dead rotator and I missed out on playing around the new 4.51 version AGC settings in the WPX CW. I'm sure those of us on the reflector who couldn't get on in the WPX CW would be very interested to see what worked out. Prior to the contest, at least one serious contester (K6LL) was going in with fast AGC, using the minimum of RF gain (no preamp) and the following menu settings: AGC Decay: soft Hld: 0.2 Pls: nor Slp: 0 Thr: 20 F: 200 AF lim: nor 030 This seemed a pretty good set-up based on my own experience - be great to hear if these setting worked for both loud and weak signals and, if not, what did. All comments would be appreciated! Many thanks!

[Elecraft] Elecraft K3 versus Yaesu FT-1000D
G'day It has been interested in reading the thread about a (or some) 'big gun' contesters still preferring the classic FT-1000D over the Elecraft K3. I used to have two FT-1000Ds (sold an FT-1000MP to buy the first one - the FT-1000D's audio peaking filter and nicer receive audio gave it the edge). I sold the first FT-1000D to buy a K3 and then sat the two alongside each other in a series of contests. I have two keen contesters nearby - one about 1km away and the other 10km away (which is a really nasty distance on the low-bands). The FT-1000D's blocking dynamic range (BDR) could barely cope, but with the K3's BDR and the 500Hz roofing filter I could not tell if the other blokes were on the same band unless they came within under one kilohertz of me on CW. On the FT-1000D, I could hear them 3 or 4 KHz away and it was impossible to operate much closer to them than 2 to 3 KHz on CW, making me miss stations regularly. Within six months I had sold the other FT-1000D and have never regretted it. The FT-1000D may look and feel a million dollars in comparison to the K3 (and is a great radio), but I know which one gets the job done better at my QTH in a contesting situation.

[Elecraft] Hardware mods, what hardware mods?
G'day It has been interesting reading the email from Howard and the various emails that followed. In regard to hardware mods, I have a K3 that is around 18 months old. It is about the only radio that I have owned over the last decade that I haven't bothered to modify - because it works so well out of the box. My FT-1000MP and its two successor FT-1000s both went under the soldering iron as soon as they were out of warranty. My passions are 160m and contesting and in a strong signal (fellow contester 1km away) and a weak signal (covered in heaps of noise) environment it kills the two Yaesus - as its performance figures, as recorded on Rob Sherwood's website, would suggest. The so-called K3 hardware fixes are minor improvements to things that aren't going to don't make a lot of difference to an operator like me - which certainly could not say the same about the stuff I had to do to the MP (serious IF blow-through/hiss cured by the Inrad IF board, plus clix on CW that could make serious enemies) and the FT-1000 (the clix again, plus some modifications to receive antenna switching to bring it up to snuff with the MP). Looking at the other radios I have used over the last 45 years (Drake B and C-lines, Icom IC736, 751A, Yaesu FT101ZD, Kenwood TS-830S to name a few) for me, it works better out of the box than any of them and sounds at least as good. With a K3 and a Softrock v6/buffer amp plus VE3NEA's Rocky (for contesting) or CW Skimmer software, running under XP on an old P4 3GHz as bandscopes, I have a set-up that is leading-edge for weak signal work, without bleeding money.

[Elecraft] Re: K3 vs HPSDR Mercury
G'day I have been using an Elecraft K3 for about a month now, which is the best performing superhetrodyne/analogue transceiver (with a great DSP back-end) that I have ever used. Once I got the filtering and DSP adjusted right, in terms of pulling weak signals out of noise it was clearly better than my previous FT-1000. I also have a working HPSDR Mercury digital down conversion (DDC) SDR receiver (the Mercury receiver board plus the Ozy communications interface) which use with the PowerSDR software. For those not familiar with SDRs, the DDC type effectively convert radio signals from analog to digital at the antenna socket, using an analog to digital converter. Mercury has a Blocking Dynamic Range of 119dB, which is basically independent of frequency spacing When it comes to pulling weak signals out of noise, on the basis of A/B testing that I've done, weak signals almost lost in noise are easier to understand and less tiring to listen to (more of the latter in a minute) on Mercury than on the K3. I am not an engineer, but a scientific journalist by profession and a CW and contest operator with some 37 years 'on the clock' as a radio amateur. I have been using SDRs for about three years (and am the co-author of the SDR column in the Radio Society of Great Britain's RadCom with my friend Phil, VK6APH who is an engineer and one of the main designers of the HPSDR). I clearly have a personal interest in SDR, but until I started using them was extremely skeptical about their performance. My understanding why the HPSDR sounds better to me than the K3 (and others who have witnessed the comparative tests) relates to the crystal filtering that the latter - and other analogue HF receivers - use. As many on this reflector will know, when noise pulses/spikes pass through a crystal filter, the phase response of the filter changes, depending on the noise frequency. However, when noise pulses/spikes pass through an ADC with a linear response - such as the LTC2208 that Mercury uses - the phase response stays the same, because the ADC treats them in a linear manner. What happens in practice is that on the DDC SDR any 'noise' actually sounds mellow and easy-on-the-ear (!), in a manner that has to be heard to be believed. In the case of an analogue radio like the K3, it seems that even one stage of crystal filtering is enough to cause a phase response to noise that eventually irritates/tires the user (certainly in my case) and makes them want to switch the radio off. I love using the K3 and find it an absolutely brilliant radio, but am looking forward to putting together a HPSDR transceiver to take advantage of the way a DDC SDR receiver deals with noise. Whether top ten contesters find DDC SDRs to their taste will be interesting to see, but as a 160m CW DXer with over 220 countries confirmed, as far as I am concerned they are the way ahead. Incidentally, I think both the Flex SDR-1000 and FLEX-5000 are QSD-type SDRs, rather than DDCs.

[Elecraft] Using Logitech A745 powered computer speakers with a K3
G'day I want to use a pair of Logitech powered computer speakers with a K3 that I am just setting up. I am guessing that the speakers can be connected to the LINE OUT jack (?). I am also curious of what sort of level I should set CONFIG: LIN OUT to - and how I can reconfigure LIN OUT from having the main receiver on the left hand channel and the sub-receiver in the right hand channel to having the left channel and the right channel both to the main receiver (i.e. so I can use AFX/binaural from the main receiver on the computer speakers).

[Elecraft] RE: New concept/tool for CW dxing
Gday For those on the reflector who are wondering what this new tool (VE3NEAs CW Skimmer) is like from a users point of view, see the review of well-known contester Pete N4ZR at: www.pvrc.org/~n4zr/Articles/Skimmer.pdf I have used Alexs Rocky software for the last eighteen months or so and, like Pete, am an alpha/beta tester of the big sister CW Skimmer software. It is an amazing program and was originally designed to help Alex VE3NEA to increase his operating efficiency in DX pileups when operating his 100W/dipole type station against those running 1.5kW and beam antennas. It is a fascinating program to use and has already been responsible for spotting a new 160m country for me, whilst I was (kindly) working a pileup of USA and JA stations on the same band. Whilst CW Skimmer spotted the station for me (as a packet cluster would have done), I still had to actually work the station through a large pile-up... ;-) Unfortunately, using the $75 CW Skimmer isnt going to help a little pistol beat the CQ WW score of a big gun contester who has a holiday QTH in the Caribbean with automatically tuned Alpha linears, stacked monobanders and four-squares, so lets not get carried away here. It also isnt going to make big gun operators of this kind any more invincible if they use it than they probably already are. ;-) On the other hand, owing to its speed of operation (when a DX station calls CQ, Skimmer is going to recognize their callsign very quickly, as long as their CW is half decent and isnt smothered in noise), it can help little pistols to work some new countries. I really like Skimmer and regard it as the best operating tool in my DXing arsenal. Of course, coupled with a K3 and using IF-based Q5er/panadaptor, its mojo may just be amazing! To paraphrase Mark Twain, the death of real CW operation now that CW Skimmer has arrived is greatly exaggerated.
