[Elecraft] FS: KX2 Shack-In-A-Box with Lots of Extras
Hello, all! Planning to list this on QRZ but thought I'd offer it here first. Everything you need for SOTA, POTA, Digi Modes. Open the box, and get started at home or afield! I've had great luck with this KX2, just not going to be using it much this year so I'd like it to go to someone who will. The only issue I've ever had was noting that on 10M, SSB power would start low and ramp up. I sent it back to Elecraft and they noted this is a software "feature" and no problem existed. However, it was also updated to most recent spec at that time and re-calibrated. A few light signs of use on the transceiver and accessories, but operationally as new. Elecraft KX2 #757 Back at factory 4/2021 for updating and calibration (harmonic suppression kit installed, C83/C98 caps updated, brought up to revision A7 from A1). Includes: KXPD2 Paddle KXAT2 Internal ATU KXIO2 Real Time Clock 2x KXBT2 Battery Packs KXBC2 Charger Quick Release Ground Plug MH3 mic LowePro Case AX1 Antenna with extra AX1E 40M extension and AXB1 Bipod BNC-BP for random-wire antennas SideKX heatsink, SideKX protective cover QRPWorks K-Board with keyboard Easy Digi for KX2 KXUSB Cable $2200 total value, for $1325 shipped. Please email me directly with questions or to make a purchase. I will not split up the bundle, no trades.

Re: [Elecraft] KX2 tx low power on 80M SSB
Elecraft indicated this behavior pointed to a failure in the output block. Since Elecraft has mine now for repair of this issue, we will get a definitive answer as to whether this is firmware or hardware. —Nate Sent from my iPhone > On Mar 22, 2021, at 12:02 AM, Reed Fite wrote: > > Dave, mine does the same thing on 10 meters.

Re: [Elecraft] KX2 tx low power on 80M SSB
Great to hear, Dave! I’ll be posting the outcome of my KX2’s trip back to elecraft, so watch the reflector if you’re interested in following along. As of now no ETA from elecraft, it’s been there about 2 weeks so far.

Re: [Elecraft] KX2 tx low power on 80M SSB
Dave, I have that exact problem with my KX2 on 10m. See my recent thread here: https://www.mail-archive.com/elecraft@mailman.qth.net/msg247537.html Elecraft support said that situation is indicative of a failure in the output stage, and my KX2 is currently back at elecraft for repair. I sent it back in early March. I will update my reflector thread with the outcome of the repair, so watch this list for details. I never use 80 on that radio, so I’m not sure if the issue existed there, unfortunately.

Re: [Elecraft] KX2 Starts Off with Low Output on 10M
Unfortunately, this did not fix my particular KX2. TX Gain calibration was completed successfully, but the same issue persists. I also did the TX bias calibration, and noted that bis on Q6 took ~45 seconds to complete, vs the 3-10 the manual suggested. Q7 was fast. Q6 wavered a lot between .3-.7v. I suspect this suggests the problem is perhaps indeed hardware-related. Thank you to everyone on the list who responded with ideas to check. I’ll get this one packed up and sent back to Elecraft. —Nate KE8QID > On Mar 1, 2021, at 10:09 AM, Reed Fite wrote: > > Mine did the same thing.

Re: [Elecraft] KX2 Starts Off with Low Output on 10M
I have replicated this behavior both with the internal as well as the MH3 external mic. Of course set at different mic gain levels, always per the manual which as you said suggests 5 bars of ALC. I have tried lower and higher mic gain settings just for fun, with the same results. I don’t think this is an mic gain issue, as it does happen on any other band I’ve used (80, 40, 20) and only on 10m. I made a video showing the behavior here, let me know what you think: https://youtu.be/7wWd6vRYSxo I have had great QSOs on 40 and 20 so far, and feedback that my audio is extremely low on 10 until it “warms up” and then reports there are excellent, also. I usually talk on 10m for 45-60 minutes every weekend morning and it performs well once it’s up to power.

[Elecraft] KX2 Starts Off with Low Output on 10M
Hello! I recently purchased a KX2 (#757) from a friendly member of this list. I have a local 10m meetup I attend frequently, and I noticed a strange behavior that I'm now able to replicate. When I first switch to 10m, I have extremely low output power (one bar on the RF meter), even when set to 10w. I have to keep transmitting for 30-60 seconds, and if I do, the output power starts to work its way up to the full 10w. As you talk, you'll see 2 bars, 3, then 5, etc eventually to the full 10w. If I switch back to another band and back immediately, it will display the same behavior (start on one bar and then climb slowly), but if I stay on 10m it will continue at full output for the QSO. I isolated this problem this morning and can now replicate at will. It's not just a display issue, my local meetup actually noticed it in audio (I start off in the noise, and come out to normal over time). I mailed Elecraft, and they suggested it was a hardware failure in the final stage. Before I return the radio for service, has anyone experienced this issue previously and found it to be a configuration issue that didn’t need hardware repair? Thank you in advance! Other than this issue, I absolutely love the KX2. It took me 3 small HF rigs to land on it, but it suits my needs perfectly. —Nate KE8QID Sent from my iPhone __ 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
