Re: [Elecraft] s/n ratio of this list
That works as long as some discussion does not start up on the [Announcement] tag. Or, if people can remember to be diligent, before starting discussion they can remove the [Announcement] tag. By the way, I already filter out a small set of e-mails (from the from: tag) because I don't want to miss anything they say. These are filtered merely by marking them with flag (Mac mail). This set is somewhat obvious and includes: Wayne, Eric, and about a dozen others whose technical expertise knowledge is far more than mine (thus, reading their messages puts me in learning mode most of the time). 73, phil, K7PEH On Jan 21, 2015, at 10:26 AM, David Cole d...@nk7z.net wrote: That would work for me...

Re: [Elecraft] [Bulk] 8 or5 Pole cw filters
On Wed, Jan 21, 2015 at 12:55 AM, Dr. William J. Schmidt, II b...@wjschmidt.com wrote: These are roofing filters, so you will only notice a difference in adjacent frequency rejection of loud signals... so if you live out in the country and don't have any loud stations near you, it’s not likely you will ever perceive a difference between 5 pole and 8 pole filters. Will beg to differ here. It certainly is not just the loud local at issue. Another is the dB between the very weak desired IN-channel signal and the very loud close-in UN-desired station that is just barely up or down from you. If I had a dollar bill for every time I was trying to copy a very weak 40m, in-the-noise EU QRP station running a noodle antenna on the floor of his basement, with a 10 kW mildly clicky Italian station up 300 Hz with a three element beam up 180 feet aimed at the US, I could buy a lot of new equipment. Of course, we were using a five element full sized quad on 40m, but the K3 showing 45 over 9 for his signal seemed high. Between DX contests I did a complete alignment and calibration. The next time I ran into that station he was only (?) 40 over 9. Or maybe that was propagation. The ambient noise was S4. That's S4 in the 350 Hz 8 pole filter (250). So I'll give the argument the benefit of the doubt here call the QRP station S4, although probably he was only S3 at best. That's a 65 dB difference (probably 70) between the wanted and unwanted. What the 5 poles do NOT have, and the 8 poles DO have, is sharply steep skirts. The problem is to drop 65-70 dB in about 170 Hz. And do it without tuning off your run frequency. Knowing those kinds of situations, the other ops would not let me put a rig with 5 pole filters on the line. The 8 pole 350 with the DSP at 350 drops 65 dB off center zero in 250 Hz. With the NB set for medium key click cancel, that takes out my 40 over 9 up frequency neighbor and most people calling him and allows me to strain to copy the noodle QRP station with nothing but ambient noise as the enemy. Do I need that in mild casual operating? Heck no. But it serves me in many more situations than just when I have another station within a quarter mile. If I took my K3 out to the contest station with 5 pole filters for CW running bandwidth, the other ops wouldn't let me put it on the line. It would be an emergency spare only. As for SSB contesting, I use the 8 pole 1.8 roofers, and it just barely uncovers some signals from interference up and down. 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] [Bulk] 8 or5 Pole cw filters
Since I operate very little on HF, then why did I buy the 8-pole filters? Because: 1. I figured they had steeper skirts for extreme operating conditions where adjacent strong signals were encountered. (very rarely happens in my neighborhood though a multi- super contesting station lies 10mi north of me). But someday I may be operating portable/mobile in the lower-48 where it will be appreciated. 2. I bought the KRX3 sub-receiver; matched filters were recommended. 3. I figured it would help re-sale value, someday. I bought: 13-KHz for FM (on VHF) 2.8-KHz (K3 required either 5 or 8-pole SSB filter) 400-Hz CW 2.8-KHz for KRX3. I wrongly bought an extra 13-KHz filter for the KRX3, not thinking clearly that the KRX3 would not be used for FM - I sold it here on the reflector after realizing my error. In practise I mostly use the 2.8-KHz roofing filter and set bw with the DSP, even on CW, which is mainly used for VHF or eme. The 400-Hz filter does appear to improve the sensitivity when running 200-Hz on CW-eme. Probably knocks down the noise bw of the receiver before the A/D converters. I avoid the HF contests and only participate in the Elecraft Net. Occasional psk-31 on 14.070, and very occasional general chatting on (mostly 20m). 99% activity is eme oriented which is 90% building/fixing and 10% operating.

[Elecraft] PX3 makes tuning in a PSK31 signal more accurately
Well one of the things I have found that the PX3 helps with is being able to more accurately and quickly to tune in a PSK31 signal verse using the CWT Tuning Aid. I set the PX3 span to 2 or 3KHz and tune the VFO so that the PX3's cursor's bold line is on one of the 2 PSK signal peaks. If you put the bold line in the center of the signal then it does not decode. I have also noticed that tuning to the left peak seems to decode better than the right. BTW, I have started posting to this reflector as the KX3 Yahoo reflector seems to have issues with messages being posted, I have noticed it takes a long time to post and when it does I have noticed my messages have been altered. -- Gary Mitchelson NC3Z Davidsonville, MD FM18 NC3Z/4 Pamlico County, NC FM15 www.mitchelson.org __ 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 Message delivered to arch...@mail-archive.com

[Elecraft] KAT500 RF tap for SDR Pure Signal
As well as using my K3 to drive my KPA500/KAT500 I am also using a Apache Labs Anan-10. There is a means of improving the linearity of the SDR transmitter using “Pure Signal” This is achieved by sampling the xmit signal and making appropriate corrections via the computer. The xmit signal is sampled at the output to the antenna and needs to be appropriately attenuated in the order of 40dB. As the KAT500 already is sampling the RF for various functions I would like to tap off the RF signal to use for this feature. I see there are test points in the KAT500 marked VFWD and VREFL but unfortunately they are DC voltages and I just need RF. So, the question is, is there a schematic diagram available for the KAT500 or has anyone been brave enough to jump is and tap of some RF for this or a similar project? I notice there is a capped off hole on the back plate which would make an ideal place to fit a connector to output the signal.

Re: [Elecraft] P3 Request
Hi Gary, You'll want to use the center frequency shift feature. Hold the Center button on the P3 to activate the function and turn the P3 knob until the DX station (VFO A) is wherever you want it to be. It works in Fixed Tune mode or Tracking mode. 73, Mike K2MK Gary Smith-2 wrote Since I often use the P3 for chasing DX in a pileup, I don't need the empty space to the left 1/2 of the screen, or rarely, the right 1/2 of the screen when I have the Dx Tx freq in the center. I'd like to see the P3 allow you to pin the DX Tx frequency to the far side and use the entire screen to pick choose where I want to transmit in split. As it is, when chasing DX pileups, I have to waste 1/2 of the screen which means everything I want to look at has to be compressed in 1/2 the space. 73, Gary KA1J -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-Request-tp7597349p7597354.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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] PX3 makes tuning in a PSK31 signal more accurately

Re: [Elecraft] [Bulk] 8 or5 Pole cw filters
K3 with sub RX here. Both with stock 2.7kHz and five pole 500Hz filters. Not a contester but haunt DX and DXped piles. I have a neighbour 300 metres away with a 9+60 signal from another brand transceiver that fills any band he is on with S5 noise, somewhat less on adjacent bands but still there. Inclusion of a band filter between his transceiver and linear cures the adjacent band problem. A visiting K3 at the same location being used on SSB whilst I was on CW was not known to be on the band until I saw a spot. A quick check revealed that I could get within +/- 35kHz before noise became a problem. At that point I was till copying a VE SSB mobile at S2-3 without difficulty. The nice thing about the K3 is you can tell it lies about the filter setup, both width and offset. Both my unmatched filter pairs have exactly the same offset, I told the K3 they had. As far as I am aware this information is only used in the maths used to set the syth frequencies to make sure the filters are suitably positioned with respect to the desired audio passband. A 500Hz filter passband window error of a few tens of Hz is not an issue. I believe the matched filters are only good for 10Hz, could be wrong there. Five pole works for me.

The problem is that the 8 pole filters have a better slope factor and do not have an offset. The offset is only important for diversity reception, and the slope factor is only important in situations where the band conditions are such that there are strong signals on adjacent frequencies -- as might be encountered in heavy contests or DX pileups. So if you are not interested in having the optimum receive capability in DX pileups and heavy contesting situations, save your $$$ and use the 5 pole filters. Some of us are more casual operators, and the $$$ savings can be significant. 73, Don W3FPR On 1/20/2015 11:17 PM, Bill Coleman wrote: On Jan 13, 2015, at 10:52 PM, Mike Zbrozek k8...@verizon.net wrote: As a cw opr that is planning on buying a K3 next month I would like to know how many cw ops use/prefer 5 or 8 pole cw filters?

Tnx in Advance Mike Zbrozek, K8XF I’m going to buck the trend a little bit. I only have one 8-pole filter — the 13 kHz FM filter. I see posts from a lot of guys who have a radio full of 8-pole filters. That’s nice — if you can afford it. Those filters are expensive. During the five years I spent dreaming of owning a K3, I had thought I only wanted to have the 8-pole filters. However, my wife (the best XYL ever!) ordered a very stock K3 for me for Christmas, and it came with the 2700 Hz (5-pole) filter. Swapping out this filter after the fact for the 2800 (8-pole) filter is even more expensive than ordering it in the first place. Because of the expense, I used the stock filter for about six months before contemplating anything. I bought the 13 kHz filter because it gave me FM and AM receive and transmit capability. I got the 500 Hz (5-pole) filter because someone offered it on this list at a greatly discounted price. The key thing to remember about the K3 is that the DSP IS your filter! You don’t have to buy any of those expensive crystal filters. PERIOD. The radio works great with just the stock filter. Do the expensive crystal filters make a difference? Yes. The 500 Hz filter makes a difference. I’ve got it configured to kick in at 450 Hz. There’s a distinct difference in the audio background noise switching to 450 from 500. During the 160m CW contest, this filter knocks down a lot of adjacent channel interference. I’m glad I have a narrow roofing filter available for CW, PSK and RTTY

We've been here at this time for the last 150 years!! ok.. fine.. But the one that gets me.. is the We can't change freq.. because no one will find us. Don't they have vfos? I'm pretty sure that most of the radios used in nets today have vfos. And.. I'm pretty sure that if the operators don't know how to use the vfo, and their own skills to find the NCS.. they need to learn how.. and now would be a good time. I'm proud of my K2(s) and I expect anyone with almost any radio to be able to operate within a few cycles of me... They do all the time now... but not for long.. I move. It's kinda funny tho.. I can move and still make Qs.. many times I tune back and find they have given up moved on, calling empty returns... on a very productive freq for me. Part of the game, I suppose.

There are documented instances where the Maritime Net has come to the assistance of distressedboaters on the high sea. Copied from the previous post. Sadly, when a major contest comes around i am forced to hide on the WARC bands. If not open then i find something else to do. I have all 8 pole filters but they dont help when a rude station blasts away less tha 1kc up/down from me running crap audio, an amp getting its ring flogged and a rig with all the knobs slammed to the right. Oh, and we cop it from EU and the US.Geography is irrevelant it seems.. No point in asking either. It is what it is i guess. 73 Gary Vk1ZZ Ham Radio is not only about Contesting! 73 Milverton.

Not snobbery at all. I'm simply trying to save people money by advising them not to buy stuff they don't need.

I take pride in a very clean and narrow signal. My K3 with power amp has a -40 dB SSB bandwidth less than 3.5 kHz. If you want to operate next to me, you need to bring a good radio to the party. And I'm not going to QSY because you don't.
