RE: [Elecraft] K2 DSP vs. Audio Filter
I agree with Ron AC7AC The K2 just by itself for cw is excellent I also have the KDSP2 but don't use it much 73 Robert G3RCE (K2 #5219) --- You might gain some experience with the K2 for a while and decide what there is about the rig without either module that you'd like to fix. The DSP has awesome capabilities but, like you, I don't like the sound of digitized audio. The KAF2 was something I had planned on when I built my K2 in 2000, then when I listened to a couple of them I sort of never got around to ordering my own - and haven't missed it. For my ears, the K2's I.F. filters do the whole job just fine. That's the inherent advantage of the K2. We have a lot of options to tailor it to our personal interests and needs. I'm 99.9% CW yet I added the SSB option for the flexibility to work SSB and digital modes whenever I wanted to do so and I've never regretted doing so. If I had been trying to logically deduce what I'd want before using the K2 as a CW op, probably I'd have skipped the SSB module and gone for one of the filters instead.

[Elecraft] F12 Sigma Vertical
I have two of the Sigma 5s here in CX land. They are extremely easy to put together...just a few bolts and wing nuts and I use a cement umbrella base with a sleeve of pvc about 2ft long and just slide the base of the vertical into the pvc. No radials as these are vertical dipoles; 50ft of control wire come with the antenna as it uses factory tuned coils to change freq. Both Sigma 5s were below 20m cw when I got them so it was a simple task of sliding off the PVC cover and spreading the coils on each end. The other coils were set at the factory and no adjustment required. My 20m 2:1 points are 14000 and 14270; all other bands are below 2 to 1; havent checked above 28.600 so dont know about that. So, how does it play? CX is a long way from major ham populations, US and EU. The antenna exhibits low angle radiation, as it should and I believe F12's claim of 90% efficiency as being pretty accurate. Granted, I have nice call sign that attracts the dx but I also work almost everything I hear. VQ9JC 4S7NE on 17m cw are recent examples. Another vertical that I used when I first got here was the DK9SQ fiberglass 33ft pole and his single element loop. It also worked very well on 40-10m but is more of a weekend antenna. My pole finally snapped in about 40-50kt gusting winds last January; this was after continually flexing for about 4 months as I had it permanently mounted via bungee cords to the patio support post. Finally, I recommend going to www.contesting.com and see the reviews of all the vertical antennas posted on eham by our colleagues..

Re: [Elecraft] Elecraft DSP vs Audio Filter?
Another consideration is the current drawn by the DSP unit, if you intend to operate your K2 from the internal battery option a fully loaded K2 (including DSP) can approach 350 mA. If the current band conditions don't require the use of the DSP, it can be placed in bypass mode where its current consumption drops to about 10 mA. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Elecraft DSP vs Audio Filter?
I'll chime in with my 2 cents... I operate 99.9% CW. I bought the KAF2 before the KDSP2 was released. I originally wanted the KAF2 for both the clock feature and the audio filter feature (I had money then, and wanted as many features as I could get in my K2/QRP). Now I seldom use either the clock or audio filter. If I use the audio filter, I'll use it at the wider setting (AF1?) - the narrow setting I might use for really rough conditions with wall-to-wall signals - but it generally doesn't see much use. The clock - well ... let's just say that since I bought my Casio G-Shock/Waveceptor/Tough Solar watch ... I get very accurate GMT/UTC from my wrist now. Would I buy the KAF2 now? Probably not - since the IF filtering does 99% of the work. BUT - first filter setting does a very nice job of rolling off the 'hiss' that you'll hear in a pair of stereo headphones ... so it does make it much more comfortable for those that must operate for a long period of time. For this reason - I'll be keeping the KAF2. If I was interested primarily in SSB - I think I'd probably get the DSP for the simple reason that it will handle noise reduction and filter out heterodynes that always seem to be a factor in SSB reception. 73!

RE: [Elecraft] update older k2
Rich, I suggest you download the K2ATOB instructions and look at the list of changes shown there - there are several 'optional' parts that IMHO should be included as part of the task. In addition to the A to B changes, add the PLL Temperature Stability mod and the Keying Waveshape mod - and while you are at it, add the 2 diodes for the Strong Signal Handling addition (there is no parts kit for this, just order 2 1N4148 diodes) - the mounting details for the diodes is on page 59 of the K2 Rev F manual. In addition, change the IF filter crystals on both the RF Board and the SSB option and rewind T7 to the turns ratio indicated in the Rev F manual. Check the resistors on the SSB option ALC area to see if the latest resistor changes have been made. While you have the SSB option crystals removed, change the SSB filter capacitors to the newer values if you desire the wider OP1 filter. Last but not least, look it over carefully for any 'special purpose' mods that the previous owner may have added and either remove them or satisfy yourself that they are useful for your purposes. Having done all that, you should have a K2 that performs up to the level of the current shipped kits. You may also want to optimize the AGC Threshold for best reception (on the pre-SN3000 K2s this involves changing the fixed resistor Control Board R1 (lower its value). 73, Don W3FPR -Original Message- I have an opportunity to purchase a second K2, serial number 008xx.

[Elecraft] K1 tx alignment: cannot hear sidetone or monitor tone
I am performing a K1 transmitter offset alignment as described on page 47 of the manual (Rev C, October 9 2000). According to the manual I should install a jumper between the two OFS pads, disable AGC, set output to 1 watt, and enter Tune mode. At that point I should hear two tones - a sidetone, plus a transmit monitor tone. I hear neither. If I key the paddles, I hear the side tone. But Tune mode doesn't produce any sidetone, nor can I hear the transmit monitor tone. Any ideas? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K1 tx alignment: cannot hear sidetone or monitor tone
This may help. K1 Builder Alert #3: Inability to hear transmit signal when making the TX Offset Adjustment 26 Feb. 2001 Impact: All K1's Background: When making the 'Transmit Offset Adjustment' (K1 Rev D manual, page 47) on some K1s no TX signal tone is heard. (This adjustment has you match the K1 sidetone frequency with the TX offset.) The reason this happens is because on some rigs we have two mute circuits that work almost too well. Q10 is a shunt mute FET, and Q11 is a series mute FET. Jumpering OFS (as noted on page 47) prevents Q10 from muting, but it does not prevent Q11 from muting. Some J309s mute so well there is not enough AF signal leakage from U3 to U4 to be heard in the speaker. TX offset can still be set using an external receiver as a reference, but the following procedure is suggested if you want to use just the K1. Modification to TX Offset Adjustment instructions. (Please read the TX Offset instructions on page 47 first.): 1. Set the RX BFO properly first (K1 Rev. D manual page 40), by adjusting C20 until maximum amplitude is found using an AC voltmeter on the AF output, or using Spectrogram to peak the AF signal on noise. 2. Then turn off the sidetone completely (StL 0). 3. Set the power level for 2-3 watts. 4. Jumper OFS. 5. Try adjusting TX BFO trimmer C13 to see if you can hear the beat note. If you still cannot hear the TX-generated tone, temporarily place a resistor of 47k to 100k across the Drain and Source leads of Q11 to allow more audio to leak into the AF amp at U4. Now you should be able to hear the TX tone well. 6. You can then increase StL to 1-5 or so to match the sidetone and TX signal levels. You may need to adjust the StL and Power level slightly so both are at about the same audio level for hearing the beat note. 7. When the TX offset adjustment is complete, remove the OFS jumper and the 47k to 100k resistor from Q11. -- JT Croteau - W6FO - Canton, GA | K1 #292 ARS #2,147 | NoGA-QRP | SEDXC | ARRL ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] 10 meter replies
Hi, Ron. See you on 10 when it opens! It's open most days at the moment afternoon. For the past week I've scanned the beacon segment around 12pm and I am consistently hearing beacons across the continental US from a receiver in London Ontario Canada. Some slow QSB but these beacons are mostly operating CW at QRP levels so QSOs should be possible. Right now as I write this (2nd June 1615UTC UTC) I'm listening to N4HLF/B and W3HH/B in Florida and KG4VVV/B in South Carolina, from London Ontario. The antenna is a 3.5m HF whip at 11m AGL feeding back to an Icom PCR-1000 via ~30m of buried Belden9913, so nothing spectacular :) I'm listening to 28.272MHz in CW mode with the IF set to 6kHz. There are a couple of weaker signals too that could be resolved with some judicious filtering, see the spectrum at: http://www.sunim.plus.com/28272khz.gif Audio file is here: http://www.sunim.plus.com/28272khz.mp3 I'm looking forward to getting my 10m highmite on the air!!! 73 Martin. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] AV620 vs. R6000
Keith, I have been using the Force 12, Sigma 5 for 10 - 20m including WARC with success. The Reno QRP Group used it for the 7th QSO Party. We logged QRP contacts from CA to ME. The antenna is a vertical dipole with a matching network at the feed point. It is only 9' tall and a base aluminum tube is added fro ground mounting. By mounting it higher above ground, local coverage is increased. Steve, nu7t ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 #3829 has grown up! :-)
Hi all! Long time since I was on list. My K2 has grown since last time. It is now a K2/100 DSP AT. The DSP and KAT100 is lates addition to the line. My K2 has worked flawless since it was build and gives me daily pleasure. Earlier I read some complaints about the KDSP beeing difficult to set. I find the KDSP to be surprising simple when I saw how many adjustments there really are. The gainmenu are my favorite. Beeing able to balance the system was a big advantage. ( still balancing my system hehe.) The thing is that the KDSP is adaptive and the use is adaptive and has to be done over time. At first when you start use the dsp you only has enough feel to set the dsp just broadly where you want it. The rest has to come with timeeg. fine tuning. When it comes to the KAT100.Well!! I bought a used Z100 for use with my FT-817..( still has my K1 witch I want sell) That was a good opportunity to bye the T-1 since the Z100 want work with the 817??? Low power specs is the same. z100 says 0,1 and T-1 says 0,5 I think. The Z100 lies. T-1 doesn't. One of the fines small piece of equipment I have ever owned. I lost my believe in the Z100 so the KAT100 was bought for my K2. Smart move! I more and more get the feeling that Elecraft want people to like their new investment more or just as much as making money while others just want to make money. It also make me feel that when I use my elecraft rigs and addons , I use well tested designs witch was build by the most trusted person on earth. Me. :-) Have a nice weekend all!

[Elecraft] K24U software compared to N4PY
I just downloaded the 30 day test version of k24u software and I've found it very easy to use. Where most all of the K2 current operating parameters are plainly displayed. Making it much easier to use the K2. Such as being able to see at a glance what the xtal filter and the audio filter bandwidth selections are. Although it dosnt provide enhanced memory functions. How does the N4py software compare as far as ease of use? I wouldnt have to write this querry if N4PY provided a way to test run his software before the purchase.Something that he should seriously consider providing. If there is someone who uses both software programs, how does the N4PY software compare to the K24u as far as ease of use? Does the N4py use multiple screens that need to be loaded separately --- and therefore increase the complexity of getting from point A to B? Or is it as easy to use as the K24u software --- where you can see and change all the primary opr conditions on one screen?
