[Elecraft] 8T 8R
I'm pretty sure I now understand the operation of 8R and 8R HOLD. Is 8T the inverse of 8R (ie goes high during transmit)? Is there a 8T HOLD option anywhere? At the moment I run 100% digital modes and I switch my linear via the RTS line on COM1 (which goes high on TX) and an opto-isolator. I would like to use the opto-isolator circuit for SSB and it looks as though the 8T line might do the trick. 73 Bob 2M0KDZ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K2 problem or is it the antenna? - SOLVED
Last night, while driving home from work, I was formulating my plan of attack. First I'd do a walk around at the antenna base to see if things are good there. I noticed the connection between the coax and the antenna was just a tad loose. I hand tightened it and then checked the system with my analyzer. All was back the way it should be. Tuner settings on 40 meters is once again wide and forgiving. I'm getting 200 KHz of more of 2:1 bandwidth and the settings are back to where they used to be. K2 is once again happy and the Palstar meter are saying I have a good match. To celebrate, I made a CW contact on 40 with the K2. Very nice Thanks for all the suggestions such.

[Elecraft] K2 / 10 dB / QRP / QRO at 15 watts.
Had an interesting time last night. Called CQ in the QRP fishing grounds (7040) with the K2 set to about 15 watts. Got a weak answer from a station in VA. Gave him a 449 and he gave me 569. Turns out I had caught him on a peak, his signal was really more like 329. I copied name, RST QTH. He said he was running QRP. I asked him for his rig and power and it went like this. fb on all keith. Rig here i ng ... w ... d ... et antenna. hw cpy? Every time he sent something that wasn't boiler plate his signal would fade into the noise floor or I'd have some QRM or QRN crashes. It took a few exchanges but turns out he was running 1 watt to a doublet. Suddenly I was the station that was 10 dB louder. I was the QRO station who had a solid signal and needed to send things only one time. When I put the rig on the air at 15 watts I expected to be the weak one. I guess he just felt compelled to bow to the K2 mojo :-) - Keith KD1E - - K2 5411 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 problem or is it the antenna? - SOLVED
Never take cables completely for granted. I recently had a Pomona BNC jumper, looked good, ohm'ed out good, but on my analyzer was BAD. It was weird! Physically looked beautiful, tested out perfect with the DMM, but wow, was it ever a baddie on the RF analyzer. Here's how to check: Put a dummy load on the end and test'um. You should see 50 ohms all across the range, SWR 1:1 across the range. Yes, I threw the bad cable in the trash, don't worry no one will buy it from me for $1 at the next ham swap meet! 73 de Alex NS6Y On Apr 20, 2006, at 4:48 AM, Darwin, Keith wrote: Last night, while driving home from work, I was formulating my plan of attack.

RE: [Elecraft] 8T 8R
Bob, Yes, the 8T line is ALMOST opposite 8R - but not quite. 8R goes low prior to 8T being asserted and 8R can be held low after RF disappears for a period of time determined by the 8R HOLD menu parameter. The 8R line is usually the one used for external keying. There is an External Amp Keying Circuit schematic (and a partial kit) on the Elecraft website. Tom Hammond has an updated version of the circuit that you can find at www.n0ss.net - this is similar to the amp keying circuit found in the KPA100. There is no 8T hold menu parameter - the 8R signal goes low 15 to 20 ms prior to the onset of RF. 73, Don W3FPR -Original Message- I'm pretty sure I now understand the operation of 8R and 8R HOLD.

Re: [Elecraft] multiple XV in high-power rover .. anyone else doing this?
John: I think I recall a post here where someone had blown up an XV front end in a rover setup by transmitting on an adjacent band (as I recall at the 100-200 W level). There's just one tuned circuit in front of the preamp FET in the XV's, so bandpass filters wouldn't be a bad idea. By the way, I will probably be including my K2 in my VHF contest rover setup this year (it got its start in the Ontario QSO Party this past weekend, on HF). It's so much nicer to operate than the current HTX-100 IF rig !! I'd be interested in any observations of how it stands up to being beaten about on dirt roads and such. The slug-tuned coils and the toroids supported only by their leads make me a bit nervous. 73, Steve VE3SMA __ Do You Yahoo!? Tired of spam? Yahoo!

RE: [Elecraft] Steppir Vertical and K-2
I have Steppir 40 meter vertical and I am very pleased with it. My worst match in any of the bands is 1.4:1 and most matches are around 1.1 or 1.2. I do not use an antenna tuner, although I have considered building a tuner since I have heard you can work 80m with a tuner, although obviously not as well as if you had a proper 80 meter antenna. My installation is on my roof, so I have two radials/counterpoises per band on a steeply sloping roof. If you can't put in a directional antenna, the Steppir is a very good choice. It should be completely configurable from the K2 and I believe that others have done so. If you look at Larry Phipps site, www.telepostinc.com he has additional software utilities he uses with his K2 and a Steppir antenna. I seem to recall that either Eric or Wayne has a Steppir vertical, so they might be able to comment as well. You use the Kenwood command set to control the Steppir from a K2. However, I started to configure the automatic tuning and decided not to. First, you pick up extra noise while the antenna is moving, obscuring weak signals. It can take some time to go from 10 meters to 40 meters. Yet the antenna works reasonably well on receive even if wildly off tune. So I often will hunt around for where I want to work without moving the antenna and then tune the antenna to my chosen frequency before transmitting. This seems to be quicker than having the antenna tune all of the time, and saves significant time when you are jumping around between bands. If I'm not jumping between bands, I'm generally in the lower CW segments where tuning the antenna to 7050, for instance, covers everywhere I want to go on 40 meter CW. (The resolution is only 50 khz, so your choices would be 7000 or 7100) So, although I have all of the options to allow automatic tuning, I don't use the feature. I strongly endorse the antenna, but am ambivalent about the automatic tuning feature. My two bits (Ok, more like 4 bits...) 73, Howard Ashcraft, W1WF -Original Message- From: John Wiener [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 19, 2006 8:46 PM To: elecraft@mailman.qth.net Subject: [Elecraft] Steppir Vertical and K-2 I just discovered the Steppir Vertical on the web.

Those marks on the KX1 PCB are correct for the KXB30 and incorrect for the KXB3080. I suspect L6 is open. Have you ohmmed it? You moved L6 to the underside of the KX1 PCB as part of the KXB3080 install. Is it in the right holes on the bottom? You should see about 1 k ohm from L6 to ground with the RF gain at minimum on either end of the inductor. With the RF gain at maximum, it should show about 1 to 2 ohms to ground. The inductor itself has a DC resistance of about 1 ohm so it'll be about 1 ohm higher from one end than the other.

Re: [Elecraft] QRP Antenna
On Feb 21, 2006, at 9:57 AM, Clark Macaulay wrote: So.how much impact on the take-off angle would you think this configuration would have? Should I replace the V with a flat- top doublet at the same 40' height which would result in most of the antenna being at 40' but still below the roof level? The key question is -- what band? The antenna will act very differently on 80m than on higher bands. The single most important dimension of a horizontal antenna is the height above ground in wavelengths. At heights less than 1/4 wavelength, the horizontal antenna basically sends all the energy straight up. At heights above 1/2 wavelength, broadside pattern starts to appear. As the height increases above 1 wavelength, the broadside pattern approaches the horizon -- low angles that favor distant DX. Lots of hams fret about the length of their doublets, but fail to account for the height above ground. While the length may affect resonance, the height affects the incidence angle of the antenna. The incidence angle makes all the difference for DX. A dipole may be (near) 0 dBd at one angle, but what is its gain at the angle the DX signals arrive (and depart)? At 40 feet, that's about 12m tall. That's a reasonably effective height for 10 and 12m. At 20m, it's barely 1/2 wavelength, so the broadside pattern starts to disappear. Below that, the antenna becomes an omni-directional cloud-warmer. The inverted-V installation will also tend to round out the pattern, since it reduces the nulls off the ends. Installing effective antennas for DX is tough, especially with limited-height supports. If you want to work DX, and your support is less than 1/2 wavelength high, consider installing a vertical antenna. Ground-mounted verticals with 30 or more 1/2 wave radials are very effective DX antennas. At my station, I have a 15m (almost 50 foot) tower with a small tribander. The tribander has a 40m dipole kit, too. I feed the whole tower as a vertical for 80m and 160m. It's not perfect, no. The 40m dipole is too low to show much of a pattern (I do see a 2 S-unit (12 dB) null off the ends), but it works better than anything else I've put up. The shunt-fed tower is only 1/10 wavelength long on 160m, but I've gotten 43 states confirmed and 10 countries using 100 watts, mostly in the last year.

[Elecraft] K2's Memory
I use one of the memories in my K2 to call CQ. It works just fine except it starts the sequence over too soon. CQ CQ de NR5A K and like 2-3 seconds starts again. Is there anyway of making the pause before it starts repeating longer??

[Elecraft] Re: K2's Memory
Jerry, Use the RPT (auto-repeat interval) menu entry to set the delay time. 73, Wayne N6KR On Apr 20, 2006, at 7:22 PM, nr5a wrote: I use one of the memories in my K2 to call CQ.

RE: [Elecraft] K2# 1068 stuck in transmit mode
Wow. I am still puzled over this one. Everything under the hood looks good. Sometimes it is easy to get a visual on an obviously blown component, but I see absolutely nothing amiss. Even passes the sniff test! The problem exists even with no microphone or key plugged in. Any of you all K2 gurus have any notions on this? I did try a reset of the K2, but that did not make a difference other than giving me an Info 201 code and resetting my displayed frequency and mode to 7100.00c . Again any help or suggestions appreciated. Thanks Mike for the previous suggestion. 73, Bill Allen - WA5PB -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill Allen Sent: Thursday, April 20, 2006 8:32 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K2# 1068 stuck in keydown! Importance: High Hey gang, I seem to have a K2 that is stuck in key down (i.e. xmit). When I turn the radio on all I get is the ELECrAFt message, that relays cycle normal, and then a frequency. No front panel controls work except the power knob and it is obvious that I am transmitting and the finals start heating up. What do I need to check or do Any and all help appreciated!

Re: [Elecraft] RTTY Filter Settings
On Mar 20, 2006, at 1:04 PM, k8rs wrote: Now, I would like to know the latest and best suggestions on the RTTY filter widths and which frequency markers to insert on Spectrogram. Do you use two markers 170 Hz apart? Depends on the software you are using. You can use the low tones of 1275 and 1445 Hz, or the standard tones of 2125 and 2295, or you can use anything in between that is 170 Hz apart, with the Mark tone being lower (assuming you use LSB, which will make the mark tone the higher frequency transmitted). Whatever your software would allow. The problem with using the higher tones with the K2 is that you may not have sufficient BFO range to program both sidebands correctly without modifying the BFO. Increasing the BFO range will reduce the precision of each step, so it may make it harder to get all the filters aligned to the same frequency. When I modified my K2 for RTTY, I ended up choosing 1500 Hz as the center frequency (mark of 1415 Hz and space of 1585 Hz) My reason for choosing this instead of the low tones is that the second harmonic of the low mark tones (2550 Hz) would be on the edge of the SSB passband. The other reason was so I could program the KDSP2 for RTTY. It doesn't allow the user to choose anything but 100 Hz increments for the center frequency As it was, I ended up changing the BFO circuit to get enough range. I added caps to C173/4 (I think that's right), but didn't get quite enough range. A 2 pf cap across one end of the crystal to ground fixed that. This mod is documented in the archives.

Re: [Elecraft] KX1 RX deaf after KB3080 installation
-- No. You have it right. Those marks on the KX1 PCB are correct for the KXB30 and incorrect for the KXB3080. I suspect L6 is open. Have you ohmmed it? You moved L6 to the underside of the KX1 PCB as part of the KXB3080 install. Is it in the right holes on the bottom? You should see about 1 k ohm from L6 to ground with the RF gain at minimum on either end of the inductor. With the RF gain at maximum, it should show about 1 to 2 ohms to ground. The inductor itself has a DC resistance of about 1 ohm so it'll be about 1 ohm higher from one end than the other. Ron AC7AC L6 is good, it measures 1 ohm. But I'm seeing only 1 to 4 ohms from min to max RF gain. That tallies with what I'm hearing- the RF gain has almost no effect on received sigs. So I'll look for whatever is pulling R1 down. Thanks again- it always helps to have a second set of eyes. 73 Bruce N7CEE ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Since part of the mod was to install T2, I'd suspect it's somewhere there. Maybe a short between the turns of the two windings since both the primary and secondary of T2 have one end at DC ground.

Re: [Elecraft] KX1 RX deaf after KB3080 installation
This sounds like the problem I had with the old 30m module, finally I just took it out and re-installed, I never did figure out what I did wrong although I'm sure one wire went in the wrong hole, then went in the right one the 2nd go. 73 de Alex NS6Y.

Ron AC7AC I can't see anything wrong with L6 or the circuitry around CA and C26. I'll lift one end of L6 tomorrow- but now I'm starting to wonder if Q7 might be shorted.
