I think this thread is straying rather far off topic. Don's program is written using Visual Basic. Therefore he probably uses the MSCOMM control to access the serial port. Whether or not he could have used another method if he had written it in another language is irrelevant, because he didn't. Most of us amateurs writing free software for other hams are not professionals and do what we can with the skills and tools that we have. Incidentally, using the API it is certainly possible to write serial port access code that works with a real serial port and not with a USB adapter. So using a third party library that has been well and truly tried and tested is probably a wise decision. - Julian, G4ILO.

The call freq on 20 Meters is 14076, we operate + or - abt 600 hz from 14076. Check it out , In the day time u can hear the tones of JT65A on 14076.

Re: [Elecraft] Filters for weak signal 160 meter CW and crowded contest bands
Dana Roode wrote: I've seen lots of discussion about K3 filters so here's my question. I've got the 400 hz 8 pole filter and it works well. During the ARRL 160 contest I had trouble running due to someone else doing so about 300 hz up the band. I was thinking about acquiring either the 250 8 pole or the 200 5 pole. Any thoughts? I have not seen any data on the 200 hz filter, but the 250 seems more like a 370 hz filter if you look at the filter plot. Which do I want? Probably the 200 Hz. You're correct about the 250 which is only ~65 Hz narrower than the 400 (which is actually ~435 Hz if my memory is correct). My 200 measures ~205 Hz at the 6 dB points so you would notice more of a difference with it even though it has wider shoulders (i.e. 5-pole instead of 8-pole). I have both a 500 and 200 and use both on 160. Normally I prefer the 500 but there are times when the 200 is very nice to have...such as in a large nearly simplex DX pileup with lots of strong stations calling. I would normally not want to use the 200 in a contest, because I would miss the guys calling off-frequency, but it's nice to have it available when necessary. Someone else asked about the filter plots on the Elecraft and Inrad websites. I believe all of these were made by George W2VJN before he sold Inrad to N5KO and AG9A. I hope Elecraft or Inrad might ask George to graph the missing filters (all 5-pole and some 8-pole) eventually (including the yet to be introduced variable bandwidth filters). If George cannot do it perhaps Jack K8ZOA could do this. 73, Bill W4ZV -- View this message in context: http://n2.nabble.com/Filters-for-weak-signal-160-meter-CW-and-crowded-contest-bands-tp2154048p2157401.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Since most of the folks here are K3 users (with built-in digital mode capability on 6m) I will add this to Ken's comments... I have worked stations as small as 100w using 5 element yagis on 6m EME using the very sensitive JT65A mode. There was no signal audible from such small stations, but the message sequences were successfully decoded and the signal trace is very easily observed on the SpecJT waterfall screen while JT65A mode is running. And I'll bet you had heard the 6m band was dead! The secret to working 6m EME with JT65A is: 1) Set up a schedule with a large 6m station and run the schedule for the hour that the moon is closest to the horizon at your QTH, so it will pass through the ground gain antenna lobes that provide the extra gain when your antenna is aimed at the horizon. 2) Choose a good time of month when conditions for 6m EME are optimum (there are good and bad days every month, depending on where the moon is in its orbit around the earth). 3) Transmit and monitor EVERY minute of the schedule. Signal peaks on 6m EME can be very short, and everything must be exactly right for you to decode the very weak EME signals. For example, two of the factors are that the polarity of the signals continually rotates, and the setting (or rising) moon must happen to be passing through one of your antenna's narrow but high gain ground gain lobes. 4) On top of everything else, it is very rare for both stations to copy each other at the same time (due to the polarity changes), so the standard EME exchanges and protocol need to be followed. These messages are automatically generated by the user in JT65A mode, and the procedure is explained there (press F5 when running JT65A mode).

Re: [Elecraft] K3 Filter Plots
I recommend Mike's program to anyone interested in their K3's filter response. It's relatively simple to use and will give you a good view of the first 60 to 70 dB of the filter response. For a variety of reasons, measuring the K3's filter skirt selectivity at frequencies where the filter's attenuation exceeds 60 or 70 dB using simple equipment and procedures is difficult.

[Elecraft] K2 power calibration questions
Preconditions: K2 #6665 25W regulated power supply. 500W dummy load paddle headphones I'm at a point where I'm calibrating the power on the K2 (pg 78-80 of the manual). Let me refer to pg. 78. Set power to 2 W ... Put the K2 into TUNE and adjust L1 for maximum output Hold TUNE, watching the display.. It starts out at 2W. I can adjust L1 to get way more than 2W. Over 7W. I can adjust L2 to get way more than 2W. When it says adjust L1 for maximum power what is that really trying to say? Above the last two steps on left-side pg 78 it says Note: [the power may go up adjust POWER to maintain between 1 and 2W] Ok so what I notice is that after I hold TUNE, adjust L1 L2 for max power (say I leave it at 7W). The next time I hold tune, it starts out again at about 2W. The exact repro case: set POWER to 2W put the green tuner tool in L1, ready for TUNE. Hold TUNE start mental timer display reads 2W I turn L1 to make it read say, 7W. I tap TUNE. A few seconds elapsed. put the green tool back in L1, ready for TUNE. Hold TUNE start mental timer display reads 2.2W I tap TUNE after a second or so. Is this normal? Differnet question: On page 78 it refers to HiCur message. I can supply 20A, but what's the recommended HiCur limit set in the K2? I just got done building, I don't want to fry it before I clean the rosin off. hi hi, or maybe it's a self cleaning radio... ;-) Page 79 -- I really can't do these tests well because I can't get a signal. What was the Elecraft mini kit for helping do these tests, I think there's a signal generator right? Page 80 For Tx alignment, what is the recommended HiCur limit set in the K2? I'm hitting HiCur only on the 10 and 12m combo as I find the peak. Thanks in advance. If the replies are made to me directly, I can summarize neatly for the list as appropriate. -jeff -- Jeff Wandling DE W7BRS K3 #2105 K2 #6665 http://w7brs.com/k3 j...@w7brs.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Sequencer keying with K3/XV-144 without rigblaster?
Dear Elecrafters: I am selling my TS-2000 and building a K3/XV-144 for EME on 2m as well as normal modes and digital on HF My question is, has anyone figured out how to eliminate using a rigblaster when using a K3 with a sequencer (LNA Technologies)? The K3 isolates the audio signals, but I don't see how I can pick off the PTT without making it cumbersome to use on HF digital modes (sequencer not used). Right now I use the LNA Technologies mic cable to pick off the PTT coming from the rigblaster, send it to the sequencer, then it comes back to the rig from the sequencer (with the preamp and amp PTT controlled by the sequencer also). This requires using a serial switch--sending the computer signals either to the K3 (or TS-2000) directly for all other digital modes, but sending it to the rigblaster when using 2m for EME. I would really like to find a solution where I don't have to constantly swap cables, or cut into the XV-144's PTT line to send it to the sequencer since this means I would then always have to use the sequencer for 2m. Any and all help appreciated. Please reply to my email directly. 73, Eric WD6DBM ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Caution when using an external monaural speaker
In a recent message, wayne burdick n...@elecraft.com wrote ... The short version is: put 1/8-W (or larger), 470-ohm resistors from each speaker output to ground. (The actual value isn't critical; anything from 330 to 1000 ohms would probably work just as well.) This can be done conveniently on the KIO3's audio daughter board, at its single-row, right-angle male connector. I see that the AF mod application note at http://www.elecraft.com/K3/mods/AF_Output_Mod_Rev_A.pdf is somewhat different to what you describe, Wayne. The 470 ohm resistors appear to be in different places of the circuit. Does this come to the same thing, or are the two resistors from each speaker output to ground also necessary? 73 -- David G4DMP Leeds, England, UK -- ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Sequencer keying with K3/XV-144 without rigblaster?
Hi Dave, You raise an interesting questionmaybe that is the elegant solution to integrating the K3 into old kluge-like VHF stations with lots of coaxial relays, homebrew amplifiers, etc. PTT output jack on the rear of the K3 could optionally be configured as a sequencer itself, so it would close an adjustable amount of time (up to a second) BEFORE any RF would be permitted to be generated after the rig is put into XMIT by either the microphone/footswicth or the serial port PTT lines. Certainly, this option would not be selected by those who want to work QSK! But they would simply not choose the option. If this option were stored by band, you could have a built-in sequencer only on certain bands, and QSK on other bands! With such an option, you would never have to worry about blowing anything up, regardless of how the K3 incoming PTT line itself was keyed ;-) What do you think, Elecraft?

Re: [Elecraft] Sequencer keying with K3/XV-144 without rigblaster?
Eric, You may be able to dispense with the Rigblaster if you activate the sequencer with the K3 KEYOUT signal rather than PTT. If you need more sequencer time than the 20 ms. maximum provided by the CONFIG: TX DLY, one of your sequencer outputs could provide the TX INH input to the K3 to hold off RF until the sequencer cycle completes. The TX INH may be set to use either a positive or negative logic state signal. 73, Don W3FPR eric norris wrote: Dear Elecrafters: I am selling my TS-2000 and building a K3/XV-144 for EME on 2m as well as normal modes and digital on HF My question is, has anyone figured out how to eliminate using a rigblaster when using a K3 with a sequencer (LNA Technologies)?

Re: [Elecraft] Sequencer keying with K3/XV-144 without rigblaster?
Lance, It has already been thought of and included in the K3 - see below. I am not sure if you are referring to the KEY OUT jack on the back of the K3 or the PTT jack. The PTT jack is an input - one would plug the footswitch into it, or alternately use the PTT on the microphone or the PTT from the RS-232 input. KEY OUT becomes active as soon as the PTT is activated - there is also a KEYOUT-LP signal on the ACC connector that acts the same as the KEY OUT jack except with a limit of 10 ma. The K3 normally transmits RF after the KEY OUT is active by the amount of time entered into the CONFIG menu TX DLY parameter - that provides a maximum of 20 ms RF delay. For those who need more time that that, there is the TX INH function that can be configured for pin 7 of the ACC connector - it can be configured for either TX INH LO=Inh or HI=Inh. This signal will prevent the K3 from transmitting RF until the inhibit signal goes away. See the K3 Owner's manual page 19. 73, Don W3FPR Lance Collister wrote: Hi Dave, You raise an interesting questionmaybe that is the elegant solution to integrating the K3 into old kluge-like VHF stations with lots of coaxial relays, homebrew amplifiers, etc. PTT output jack on the rear of the K3 could optionally be configured as a sequencer itself, so it would close an adjustable amount of time (up to a second) BEFORE any RF would be permitted to be generated after the rig is put into XMIT by either the microphone/footswicth or the serial port PTT lines.

[Elecraft] FS: Complete QRP/QRO K2 Station
Have decided to sell my K2 station and go a different route. It is in very good condition, both electrically and physically, non smoking environment. Elecraft K2, serial number 2295. Has the latest firmware (2.04P/1.09) and the following options. 100W PA (separate enclosure) SSB 160 meter Noise Blanker Audio Filter (analog, not DSP) 20 watt Tuner 100 W Tuner (separate enclosure) RS232 option Battery option MH2 mic Yaesu main tuning knob External speaker in Elecraft enclosure ( same size as the K2 case, with audio amp like what is on the Elecraft site) The radio is set up for QRP/QRO with the 20 watt tuner/battery and RS232 in the QRP cover. The 100 Watt PA and 100 watt Tuner is in an external Elecraft enclosure. The external Speaker is in another Elecraft Enclosure with an audio amp. All interconnecting cables, power cords and manuals included. This is a very nice setup and it works extremely well. It does have a varying power output when using the external amp. When it is key down, the power may vary 10-15 watts depending on the band. It has no effect on the actual operation. This is well documented in the Elecraft archives and there is a mod to change the value of R98 in the K2 to help settle this down, but I didn't find it necessary. Will sell the entire package for $895 plus shipping + insurance. US Postal money order or PayPal (with 3.5% fee). Can send pictures if needed.

[Elecraft] Request for NR and NTCH inside AGC loop
NR seems to be quite effective but especially for weak signals it drops the signal strength by up to 20db. NTCH is also outside the AGC loop. I also suggest the following refinements to NTCH: - faster or adjustable notch time in automatic mode. Now it takes a second and does not work if the carrier is slowly drifting. - adjustable width in manual mode; e.g., can be adjusted by buttons 1-4 For instance 1=20Hz, 2=50 Hz, 3=. The current one is 250HZ and is wide. It may be the same code to put both NR and NTCH into the AGC loop. Would anyone agree that these features will be worthwhile? For me several times NR 3-3 made a difference between a copy and no copy for weak signals but the volume was too low.

Re: [Elecraft] K3 Caution when using an external monaural speaker
Hello David: Wayne asked me to reply since I prepared the application note. Only two resistors are needed, so if you've done the mod using the daughter board locations Wayne originally mentioned, you're all set. The version shown in the app note mimics what Aptos is doing as they modify the boards in inventory. The resistors are in the same place electrically, but they chose to put them on the main KIO3 board instead. We followed that in the application note so it'd be easy to tell if the modification has been made either in the field or at the factory.

[Elecraft] K2 #6662 S-Meter Alignment
Hi there, So, I've made it through Alignment/Test 2. All numbers right down the middle, save the AGC threshold voltage, which was solved by adding 10k across Control RP6 pins 34. So, I complete the S-Meter alignment per Alignment/Test 1. No problem. Then, after I finished Alignment/Test 2, I figured I'd attach the XG2 to get a little bit more accurate. So I attach, follow the directions to a T, tune to 7040.30 (where I find the 40m signal to be loudest) and adjust S-Hi to show S9 for 50mv output. Well, I can't get it to land right on 9, but 9 +/- 1 bar. However, per the directions, I'm told that once I turn the XG2 off, the S-Meter should drop to 0 or 1 bars. However, it stays the same.

Re: [Elecraft] Filter bandwidth
Your operation is as expected. Note the information from the release notes for the current (beta) firmware: * AM DSP BANDWIDTH DISPLAY NOW SHOWS *AF* BANDWIDTH, NOT IF. We originally showed the IF bandwidth in AM mode since some operators might be thinking about the underlying AM-mode implementation (i.e., the IF bandwidth has to be twice the AF bandwidth in this mode). But this was causing a lot of confusion, and was inconsistent with the way the DSP bandwidth control works in other modes, where the *AF* bandwidth is displayed. Also, LO and HI CUT show AF cutoff points - not IF - even in AM mode. So we now consistently define the function of all DSP controls as showing AF frequencies/ bandwidths. 73, ...

Re: [Elecraft] Sequencer keying with K3/XV-144 without rigblaster?
Hi Don, Thanks for your suggestion regarding the TX INH function. I suppose that is one approach that would work, although it does not address the question of providing up to a second delay within the K3. If an outboard timer system or sequencer were used, then a voltage could be applied to the TX INH as you suggest Of course, if an external sequencer has to be used anyway, then the sequencer might as well just trigger the PTT line of the K3 after the required safe delay. Unless I am totally missing the boat here (which certainly happens), it seems to me that the cleanest way to make the K3 flexible enough to replace existing equipment requiring external sequencers, would be to be able to adjust the time between K3 PTT keying and the KEY OUT jack and/or KEYOUT-LP pin (or some other available pin) closure between standard short delay (20 ms) or a long delay (for example, selectable between .2, .4, .6, .8 or 1 second). Obviously, if a long delay option was selected, you certainly run the risk of chopping off syllables or CW charactere if the VOX control were used, so maybe it only makes sense for an option like that for a long delay only be available when VOX operation is not activated. To me, one of the most attractive things about the K3 is its incomparable flexibility... and I just love that it keeps getting even better and packing even more functions into that same single feature-packed little package! VY 73, Lance Don Wilhelm wrote: Lance, It has already been thought of and included in the K3 - see below. I am not sure if you are referring to the KEY OUT jack on the back of the K3 or the PTT jack. The PTT jack is an input - one would plug the footswitch into it, or alternately use the PTT on the microphone or the PTT from the RS-232 input. KEY OUT becomes active as soon as the PTT is activated - there is also a KEYOUT-LP signal on the ACC connector that acts the same as the KEY OUT jack except with a limit of 10 ma. The K3 normally transmits RF after the KEY OUT is active by the amount of time entered into the CONFIG menu TX DLY parameter - that provides a maximum of 20 ms RF delay. For those who need more time that that, there is the TX INH function that can be configured for pin 7 of the ACC connector - it can be configured for either TX INH LO=Inh or HI=Inh. This signal will prevent the K3 from transmitting RF until the inhibit signal goes away. See the K3 Owner's manual page 19. 73, Don W3FPR Lance Collister wrote: Hi Dave, You raise an interesting questionmaybe that is the elegant solution to integrating the K3 into old kluge-like VHF stations with lots of coaxial relays, homebrew amplifiers, etc. PTT output jack on the rear of the K3 could optionally be configured as a sequencer itself, so it would close an adjustable amount of time (up to a second) BEFORE any RF would be permitted to be generated after the rig is put into XMIT by either the microphone/footswicth or the serial port PTT lines. Certainly, this option would not be selected by those who want to work QSK! But they would simply not choose the option. If this option were stored by band, you could have a built-in sequencer only on certain bands, and QSK on other bands! With such an option, you would never have to worry about blowing anything up, regardless of how the K3 incoming PTT line itself was keyed ;-) What do you think, Elecraft?

Re: [Elecraft] Filters for weak signal 160 meter CW and crowded contest bands
I was thinking about acquiring either the 250 8 pole or the 200 5 pole. Any thoughts? Dana, K6NR Hello Dana. At my noisy QTH in Fairbanks, I often use the 200 Hz filter at a BW of 100 to 200 on 160M. I have both the 500 and 200 filters, but to get the QRN down, and maybe improve the S/N, the narrow filter and setting is best on what is often weak DX for me. On my small city lot I use a rotatable receiving loop (Wellbrook), which can hear better than my Inv-L most times. Also play with the AGC Slope (~3), Threshold (~6-8), CW pitch (~450-600 Hz), and filter insertion loss compensation (~4-6 db) to peak the weak sigs.
