Re: [Elecraft] K2/100 and KAT2
I researched this at one point also, and I believe you can't have them in there at the same time. There's not room for the KAT2 and the KPA100 both in the same top cover and I don't believe it'll even work electrically. So you're pretty much stuck with one or the other and an external tuner in the case of the K2/100. If I go QRO, I'm soon to have 4 10W rigs so I'm looking at the KXPA100 with a tuner in it. And just using that with all the rigs, one at a time of course. For my K2's, that'll involve putting in a keying circuit and of course that's going to be the 2-boxes thing when I go /p. Haven't definitely decided on it, but that may be the most economical option for me. 73, LS W5QD -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-100-and-KAT2-tp7616420p7616423.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] K2/100 and KAT2
Ted: You might look into building the K2/100 in the 'Twins' configuration. To switch from 100 watts to qrp just requires disconnection the power amp box. This configuration allows the KAT2 to be used along with the high power tuner. I built mine that way and it works very well.

[Elecraft] Headset PTT Options
All, At the risk of this request being lost in the euphoric response to the K3 K-Pod. I'm wondering what options you might be using / prefer to provide the PTT function for a K3S connected headset. I know options including (1) VOX, (2) PTT button on an alternative plugged in microphone, (3) PTT pickle switch, (4) PTT foot switch. What about your preference for enabling several (ie pickle and foot switch) of these in parallel Mike VK1OO __ 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] K2/100 and KAT2
A question for those who have the K2/100 --- I finished building and am now becoming familiar with operating the K2/100 and the KAT100-1. It’s a great combination; but for portable work it’s heavy and there are two boxes. At the time I bought it I did not purchase the KAT2 – the internal low power tuner. My questions have to do with having both the KAT2 and the 100W amp. Installed at the same time. I tried investigating this in the manuals but for some reason the link to the online KAT2 manual isn’t working tonight. Two questions. First, is there a physical space problem if a K2 has the 100W option, and the KNB2, and the APF/Clock option ,and the KAT2, or can the KAT2 stay on board even when the 100W amp is in place? Second, does the system switch automatically from the KAT2 to the outboard KAT100-1 when the amp is in (or when the power exceeds the KAT2’s limit?) What I mean to be asking is whether having the KAT2 inside will complicate the process of removing the amp to go “barefoot” with the base K2. As it stands now it’s six screws twice, five plugs, and no configuration changes. Does having a KAT2 on board add anything to that? Thanks in advance . . .

Re: [Elecraft] K2 SSB Monitor
While not exactly what you are looking for in monitoring your output signal, this is the way I set up my audio on my K2. This was published back in May 2009 in QST Hints and Kinks. Many of the new rigs have the capability for one to listen to transmitted audio, for setting up levels, compression etc. The problem is that listening to your audio, while speaking it is difficult to comprehend differences in settings. I simply use my PSK31 interface to record into the sound recorder of my computer and then play it back. This eliminates the problem of speaking and listening at the same time. When I do this I actually state into the recording the various levels I have the compression etc set at, then reset them at another value and make another recording. Then play back the recordings. This permits me to listen to the audio files and know what is going out on the air, with different audio levels and settings. The PSK31 interface is also useful when someone asks how their audio sounds. Simply record it into the sound recorder and play it back for them using the PSK31 interface. I often do this and then Email them the file, that way they are hearing exactly what I heard with out the effect of my rigs audio on the recorded audio I play back. 73, Steve K4JPN __ 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] K3 sound recording
Hi, An audio splitters is just a plain T junction and can not be used in reverse. That will probably just produce lots of distortion as the the low impedance audio sources are fighting each other. What K7HP is suggesting, however, using a pair of resistors to form a summing junction from the two outputs should work but will of course involve a little bit of home brewing.

If you try to use the "enhanced" cabling setup in the Owner's manual that uses the accessory cable, the K3 will control which band the KPA500 is on.

Re: [Elecraft] K3 sound recording
Unless I am missing something in your description, the only hardware you need is a single stereo patch cable (one with 3.5 mm stereo plugs on both ends) from the stereo Line Out jack on the K3 to the stereo Line In jack on a standard 2-channel sound card. If your sound card has only a mono input, use a different sound card (one with stereo inputs). In the Windows setup for the sound card, make sure it is configured for two channels. The main RX audio will be recorded in the left channel and the subRX audio will be recorded in the right channel of the stereo recording. Transmit monitor audio will appear in both channels. On playback through headphones, you will hear the main RX in your left ear and the subRX in your right ear. For dual-RX RTTY with the identical hardware, run two separate copies of your RTTY program(s), one copy configured to use the left channel of the sound card (for the main RX) and the other copy configured to use the right channel of the same sound card (for the subRX). 73, Rich VE3KI K7HP wrote: I [...] have not figured a way to record the SUB rx output at same time unless I made some sort of external circuit xfmr or resistors to feed LINE OUT tip and ring to a single input Maybe there is something I am missing ?

From: lstavenhagen To: elecraft@mailman.qth.net Sent: Friday, April 15, 2016 9:57 AM Subject: [Elecraft] k2 continuing on (nothing to lose) Hi all, Tnx for all the encouragement and suggestions by PM and on the list on my K2 tragedy. After thinking it over after something to eat I decided I didn't have anything to lose by simply continuing on. My thinking was, ok, this is a learning experience, right? So I figured, ok, let's learn how to remove a component without tearing everything up LOL. If I could get the second ruined relay out without doing more damage to the board, I was ok. I did manage to get the pads back down on the first relay socket and I didn't see that the traces were actually broken. So I carefully threaded the new relay in and soldered it in like normal. Fingers crossed that all the connections are good. As for other relay that I ruined, I robbed a relay out of my KAT2 kit and got out my desoldering iron from Radio Shack. Not the best desoldering tool in the world and it has failed me in the past, but marginally better than desoldering braid and nothing else and went to work. After sucking out as much solder as I could on the pins, I flush cut them as far down as I could go and went over the pads again with the iron and braid. Fortunately, this relay came out easily after cutting it in half on the topside with the wire cutters. No damage to the board. At that point, I was cooking with gas and decided to install L33 and the remaining diodes. That put me at the alignment part II stage. By about 10pm last night I'd complete the receiver alignment and all those circuits checked out virtually perfect. So the RX is intact and receiving on 40M. I hear relays click when I go through the bands - the 20m bandpass filter is where I did all the damage and replaced the relays, so maybe they're hooked up and working right. Anyway, at this point, since the RX is fine and working normally as far as I can tell, I think I should just go ahead with the rest of the build and see what happens on 20M when it's done. Like Wayne suggested, if there does end up a problem on 20M at the end, I can probably just run wires on the bottom of the board to hook it all up. It'll do me good to go back to the schematic anyway lol. So onwards with the build and hope the rescue effort succeeds hi hi.

Re: [Elecraft] k2 continuing on (nothing to lose)
I concur with the recommendation for a Hakko Desoldering tool. The Hakko 808 has been discontinued but I bought the Hakko FR-300 (the new and 'improved' version). I use Weller solder stations but the Hakko FR-300 saved my bacon. I had just soldered a DIP IC in backwards (completely pilot error) and following suggestions from the list I bought the new version to try to save the DIP IC. All I did was add a bit of solder where the solder braid had partially removed it and desoldered each pin in order - the DIP IC lifted out. I didn't have to sacrifice the IC or the board. As I recall the FR-300 was about $260 from Amazon. This list has helped me on more than one occasion and I'd like to thank those who participate.

Re: [Elecraft] New Elecraft Product: K-Pod Control Panel for K3S and K3 Transceivers

[Elecraft] OT: "Octopus's Garden"
Try interconnecting K3 and KX3 to support 17 ham bands from 600 meters to 10-GHz! http://www.kl7uw.com/station%20layout.htm Note the station block diagram (scroll down a page). Then scroll down to the photos (circa 2010). This is an "octopus's garden"! Wall plate for cable ingress has 10 N-connectors and 11 UHF connectors and about as many control lines exiting the station. There are more than 17 antenna. Only half the stuff was installed in 2010. Feel free to roam the website which will show you more of "my stuff". Most of you aren't even close to an "octopus" ;-) 73, Ed - KL7UW PS: Plans now to build onto the 24x28 foot garage a 26x18 foot ham shack (all wiring will have to be re-run- ugh).

Re: [Elecraft] New Elecraft Product: K-Pod Control Panel for K3S and K3 Transceivers
Looks right Joe, Not knowing if the K-Pod is a 3.3v versus a 5V device, it is hard to predict. If 3.3v, the 120R on pin 2 could be removed and keep the protection of the BAT54 zener, leaving barely enough voltage for a 3.3V dropout regulator in the Pod. If 5V, shorting the 10K on pin 6 would likely be the route. Since the K-Pod also provides a USB port, my bet is will be a pin 6 modification as it will require 5V to be "normal". What ever the mod, it stands to reason that the guys would try to keep the port operational in it's original purpose as well. Pin 4 (PGD) and Pin 5( PGC) will obviously be for data in the undisclosed format :) Whatever the mod will be, it will involve tiny smd chips... Diagram snip here: https://dl.dropboxusercontent.com/u/24789865/K3_ICD-2_page22_Front_panel_MCU.JPG It looks like a bust to migrate the K-Pod to the KX3, as all of the pins definitions on the internal "ACC" connector are switched all around, not to mention it's a 3.3V setup and the connector isn't brought outside. Would be a more serious modification indeed.

Re: [Elecraft] New Elecraft Product: K-Pod Control Panel for K3S and K3 Transceivers
You need to solder one end of an 1/8th-watt resistor to an SMD, and the other end to a via nearby. Or you could send it to us to do the work. Or you could power the pod from the radio's 12-V output, or a separate 12-V supply. Powering it from the radio one way or the other is a good idea since the pod itself doesn't have an on-off switch.

Re: [Elecraft] New from Elecraft: High-Performance 200-Hz, 6-pole Crystal Filter
Typical loss of the 5- and 6-pole 200-Hz filters is about the same. I believe we do have enough DSP-based gain compensation for all filter types, but I'll ask our techs to verify this. The noise figure of the radio is established ahead of the crystal filters, so moderate loss in the filters is not significant from a performance standpoint. In fact the sensitivity and dynamic range of the radio are typically maximized when this filter is used.

After thinking it over after something to eat I decided I didn't have anything to lose by simply continuing on. My thinking was, ok, this is a learning experience, right? So I figured, ok, let's learn how to remove a component without tearing everything up LOL. If I could get the second ruined relay out without doing more damage to the board, I was ok. I did manage to get the pads back down on the first relay socket and I didn't see that the traces were actually broken. So I carefully threaded the new relay in and soldered it in like normal. Fingers crossed that all the connections are good. As for other relay that I ruined, I robbed a relay out of my KAT2 kit and got out my desoldering iron from Radio Shack. Not the best desoldering tool in the world and it has failed me in the past, but marginally better than desoldering braid and nothing else and went to work. After sucking out as much solder as I could on the pins, I flush cut them as far down as I could go and went over the pads again with the iron and braid. Fortunately, this relay came out easily after cutting it in half on the topside with the wire cutters. No damage to the board. At that point, I was cooking with gas and decided to install L33 and the remaining diodes. That put me at the alignment part II stage. By about 10pm last night I'd complete the receiver alignment and all those circuits checked out virtually perfect. So the RX is intact and receiving on 40M. I hear relays click when I go through the bands - the 20m bandpass filter is where I did all the damage and replaced the relays, so maybe they're hooked up and working right. Anyway, at this point, since the RX is fine and working normally as far as I can tell, I think I should just go ahead with the rest of the build and see what happens on 20M when it's done.

Re: [Elecraft] New Elecraft Product: K-Pod Control Panel for K3S and K3 Transceivers
I think they are using pin 6, the one with the 10K resistor, to get +5V to the pod. So it probably will involve bridging the 10K resistor with a smaller value.

Re: [Elecraft] New from Elecraft: High-Performance 200-Hz, 6-pole Crystal Filter
The 6-pole filters have an offset (like the 5-pole). The offset is clearly marked on the filter and can be entered into the filter configuration page using K3 Utility.

[Elecraft] K2 SSB MONITOR
I know I'll be told to just buy a K3 or KX3, but I love the K2 and am always looking for ways to improve it. In the menu using SSBA and BAL it's possible to monitor SSB in your headphones. What I'm wondering is if there would be a way to make that feature active when actually transmitting so your voice could be heard in the phones.

Re: [Elecraft] New from Elecraft: High-Performance 200-Hz, 6-pole Crystal Filter
The plots have a disclaimer that one can't compare the passband attenuation for the filters. Some of us have noticed that with the old 200 Hz 5 pole filters the amount of gain available to compensate for it was not enough. I observed that here by comparing SPECTROGRAM peak outputs per filter. Presumably the 6 pole 200 Hz filter will have a bit more attenuation. How does the passband loss of the new/old 200 Hz filters compare? 73 de Brian/K3KO On 4/15/2016 2:17 AM, Wayne Burdick wrote: Some of you may recall that we discontinued our 5-pole, 200-Hz filter last year.
