[Elecraft] [K2] QRP K2 for sale
Due to health and financial issues, my QRP K2 needs a new home. This is #6391, the second K2 that I have built. Radio has 60M, 160M, SSB, noise blanker, analog audio filter, internal battery, internal tuner, and Elecraft hand mic. The only non Elecraft mod is a 1/4" phone jack for a straight key on the back panel. I am asking $850 including shipping to anywhere in the United States.

[Elecraft] Re. - O.T. UPS delivery
Most hams get a lot of UPS deliveries. I am both a ham and restore old cars. I got to know my UPS driver well. If I know I have a package coming, I try to flag him down and let him know. Then I leave one of my cars unlocked, he puts the package in the car, and locks it up! Probably against protocol, but if both of you are OK with it, fine. If he delivers while you are at work, look for him in your neighborhood on you way home and flag him down. Mr. UPS is a good man to be friends with, and every one I have ever dealt with has been a real nice fellow. Also, once Elecraft gets to know you as a customer, I have had no problems getting things shipped to my work or my parents house. I even got the mailman to be good this way, too, but he's a friends uncle.

[Elecraft] K3 - chuffing noise in AM sync RX
I just upgraded to MCU 3.67 and DSP 2.49. I had been running MCU 3.63 and DSP 2.46. Noise happens with either one. Listening to KDWN 720 out of Las Vegas with sync AM, USB selected (tried LSB, too), with the CWT carrier tracking turned on. The radio jumps around 0.720.000, +/- .002 or so as I guess it will do. When going from 0.720.000 to 0.719.999 or vice versa there is a chuffing sound in the audio. Turning off the CWT makes it stay on whatever freq I dial it to, so there is no problem. Tuning across this point makes the same noise even in normal AM mode. I only noticed this since the radio was tuning itself with CWT activated in sync AM. Has anyone noticed this on this freq or any others, or more importantly, in the ham bands? No big deal, but the firmware people might be interested. 73 Josh K6ZRX Napa, CA __ 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
[Elecraft] K3 - 2 meters and MARS/CAP
I just ordered the 2 meter option and the new wattmeter. On the VHF module, will it be able to work on MARS/CAP frequencies and/or RX outside the ham band? Just curious since the K3 is slowly replacing almost all the other radios in my radio room as more features and options get added. Th3 K3 seems to do almost everything. I hunt down DX when I'm in the mood, talk with friends on 160 meters, but mostly work my 6 meter repeater on the main VFO and listen to 910 KNEW on the sub receiver. 73 de Josh K6ZRX __ 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
Re: [Elecraft] K3 going mobile?
Robert, I have used my K3 mobile a few times. Be sure you have a good, heavy power lead that goes directly to the battery with the proper fuse near the battery. If you are going to run mobile for the long term, maybe install some Jack Nuts (like Molly bolts in drywall, but for metal) and fabricate a bracket. See if there is a tech bulletin from your car's maker on mobile radio installations. They might have some warnings on where to run antenna cable. Be sure you use a high quality double shielded antenna cable. I oversee radio installations in patrol cars, and keeping he RF where you want it is important. I can't tell you how the K3 noise blanker works on ignition noise...My car is Diesel.

[Elecraft] K3 - Another feature request
OK, since everyone is voicing their desires for K3 features, here are mine. Let me start off that when not working HF, the K3 sits on my 6 meter repeater frequency, and gets a lot of use there. I have discussed with Wayne in the past about CTCSS decode and reverse phase burst on CTCSS. I was thinking with that nice keypad doing nothing on TX that when in FM mode, it could send DTMF tones. I would like it, but who else might, I don't know. Maybe something for the way back burner. The K3 appeals to a wide range of users for various reasons. The 6 and 10 meter FM is what sold me on the K3. Some of us like FM DX and working distant repeaters when the band is open. I know I like hearing distant voices come in on my machine. 73 de Josh K6ZRX __ 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
[Elecraft] K3 - KAT3 C10 blew up!
After running a little Olivia on 80 meters last night at abour 40 watts, I switched over to my 6 meter repeater channel to call a friend. Upon keying on 6, I heard a little "pop" from the radio area. Didn't think too much of it, just thinking it was expansion of the case from transmitting (it's cold in the radio room.) This morning I was playing around with the new auto calibrate and noticed bad SWR on 15, 12, 10, and 6 meters with the tuner bypassed and transmitting into my IFR1900 service monitor. Power seemed low at the higher settings, but I thought it might be the power cable that is wee bit too small. Then there was a smell...Not the normal burned electronics smell, but a sweet, smokey smell. I decided to look inside and also to pull the synth to put in the 56k resistor per the new mod. Carrying the radio to the bench, it rattled. C10 on the tuner decided to blow up, so it's a call to the big E tomorrow for a replacement. Everything else looks fine except for some residue on the relays. I wonder why this happened. Radio ran fine on 80, and this happened the first keyup on 6 FM, using a memory channel for the 6 meter freq. I have run data at more power for longer times in the past with no problems. And the KRX3 comes tomorrow Josh K6ZRX ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Phillips "hold-tite" screwdriver mod
If you have a phillips head screw just getting ready to strip out on you, just put a touch of valve lapping compound on your screwdriver. The grit will give a little extra grip to help prevent slippage. Works great, but finding valve lapping compound is a bit hard these days. I drive a Plymouth with a flathead, so it's in my shop. 73 Josh K6ZRX On Tue, 2008-11-25 at 15:50 -0800, Barbara Maloney wrote: > > Hello list members, > > I found a trick for holding small screws on the end of the screwdriver > > until you can get them into a tight place and started.

Re: [Elecraft] OT - Looking for a "code buddy"
Thanks to everyone here, I have no shortage of help with my CW! I now have some guys to work with me, and some friendly frequencies to visit. Now all of you know my call, and that I am new to CW. It was also pretty neat to have my first QSO be someone from the group here. Cookie was really great on the air, and I really started to get comfortable with the code as the QSO progressed. Oh, and I didn't cheat too often with the K3's decoder. Only a little bit in the beginning, then I felt more at ease, and copied better. Thank you all so much for the advice (get on the air and call CQ) and encouragement. I will be checking out the SKCC and the resources there. 73 Josh K6ZRX K2/100 6097 K2/10 6391 K3 722 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] OT - Looking for a "code buddy"
I have decided it is time to learn morse code! I have been using the computer for practice, both sending and receiving. The K3 in test mode makes a great practice oscillator. I made my first, very slow, CW contact today on 20 meters to a very patient ham in Texas. It was probably the most nervous I have ever been on ham radio. I would like very much to have a kind, patient, but honest (brutally so, if necessary) local ham to work with me on the air a little while each week. Please contact me off list to set something up if you are willing to assist me in my learning.

[Elecraft] K3 - Latest firmware (last nite) FM test results, not good for U.S.
I brought the K3 (#722) to work today once again, this time to check the FM operation of the radio. I had calibrated the oscillator a couple of weeks ago, and it has only drifted 16Hz since then! Measurements taken on the same equipment, same freq standard Motorola 2670, Spectracom 8195A. My FM measurements were as follows: Frequency was 52.525, did not check 10 meters. 12Db SINAD .47uV -113.4dBm Looses squelch (13) takes .79uV -109.0dBm to break Squelch closes at .33uV -116.5dBm Max modulation acceptance 4.90kHz TX CTCSS deviation .3kHz (at 114.8Hz) Maximum mic deviation 2.0kHz (at 1000 Hz mod frequency) Max overall deviation 2.29kHz (above two tones) Here are the issues. The TX deviation and RX mod acceptance are for narrowband operations. We need the CTCSS to be around .6kHz deviation and mic audio around 4.2kHz or so. Maximum overall deviation should not exceed 5kHz. In the US we are still "wideband" on these frequencies, in both commercial and amateur service, emission designator 20KOF3E. We need more deviation to sound good here in the US. That said, the recovered TX audio waveform looks great! With mic gain turned up all the way with the Elecraft mic, there was no distortion at all on the mod scope. Looked really nice, better than a $14k Motorola Quantar. Very nice modulation. It also simply takes too much signal to break squelch. Loose squelch should be able to break below the 12dB SINAD point. So, please more TX audio, or a way to select wide/narrow if narrow is needed elsewhere in the world, and better squelch action. So, for now, still on the MASTR II for 6 meters... 73 Josh K6ZRX ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K3 - Band Decoder
OK, now that the Katiegram has arrived, I need to think about antenna switching. I have the following antennas that I want to use with the K3 Windom for most all bands Yagi for 20 meters Yagi for 6 meters (goes to the XV50) Vertical for 160 meters Vertical for 6m FM (which is not used with the K2) Right now, I have a KRC2 that switches the 20m yagi and 160 vertical on antenna port 2 on the radio. Since the K3 has 4 band decoder (TTL?) lines coming out of it, it is easy enough to build logic to pull in the right relay. Can the "DIGOUT" line be used (with proper buffering, of course) to switch a relay for changing from horizontal to vertical on 6m? Basically, windom and 6 meter antennas to antenna port 1 (with the band decoder switching from windom to 6 meters, and digout selecting wither the vert or horiz) and the 20m beam and 160 vert switched on antenna port 2? I have several RelComm RDL-SR002 relays, one of which I am using with the KRC2 now, so quality relays are not a problem here. Sorry if this is a bit long, but without equipment in front of me, I have a hard time visualizing things. 73 Josh K6ZRX ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Help me buy a DMM
Doug, My first post here is my DMM advice. When I was younger, i bought cheap meters. They worked but not for long, just wouldn't hold up to field work. I got smart and spent the $175 for a Fluke and have never regretted it. Here's some advice, no matter what brand you buy... Look at the sample rate. The better meters take more samples per second, so the display is updated more often. Some cheap meters only update the display every second or so. You will miss peaks and dips when tuning circuits because of this. My Fluke is pretty fast sampling, but I still use an old Motorola analog meter for some tuning applications. Hope this helps in your purchasing decision. 73 Josh K6ZRX K2/100 #6097 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
