Re: [Elecraft] Field Day Report
Without shame, I am hereby checking in with my 5 SSB QSOs using my barefoot KX3 and PX3 at our weekend camp on picturesque Lake George. Hey I broke some serious pileups to get them. I deserve some cred. :) Flying the end fed antenna end from my WonderPole, the owner of the camp espied me and asked, "Nice pole. What are you after?" "Electrons," I answered with a straight face. His face broke into a big sunny smile. Turns out he's not only interested in hamming himself but also runs a private girl's school and they are heavy into the STEM thing (no "A", please) and we ended up our f2f by making plans for a Skype session for the girls for later this year for me to chat about that voodoo that we do. I did offer him a GOTA session. Sadly he never made it over. He was busy opening cabins and getting his properties ready for the summer. After I was done and packed up, the nieces and nephews took a page out of my kids' playbook by chanting "Whiskey Charlie Three Tango" for the rest of the weekend. Hey, I've been called worse. I have lots of notes on what went wrong (the two biggest: CW CW CW is next on the priority list. And either configure digimodes to run on this laptop or get a more powerful one) and what went right. As Ahnold would say, "I'll be back." On Sun, Jun 24, 2018 at 23:40 wrote: > FD was a hoot from the farm here in southside Virginia.

All combi ned, we spent a good four hours of our Field Day talking to these and others... time well spent, we thought, showing (as the W1AW Field Day message said) that amateur radio is "alive and well".

Re: [Elecraft] KX3 Tech Question
Jim, S9 (or S9+5) is in the right ballpark with a 50 uV signal. This applies to the preamp-on case for all of our rigs. Also, if you can hear a -143 dBm signal, you’re doing just fine :) I suspect there’s some other reason for the loss of decodes on 6 m. Make sure you weren’t in SPLIT, didn’t turn off the preamp, didn’t turn on the attenuator, and had RF GAIN set to -0 dB. Also set COR LVL to the default (0.1 W, or +20 dBm). Note that the KX2 and KX3 both have high-signal protective features born and bred during close-quarters HF Pack operation. Depending on the offending signal levels, they will automatically turn off the preamp, turn on the attenuator, turn off an IF gain stage, or even open all of the LPFs. We’ve tested these features by injecting levels up to 10 W directly into the antenna jack. 73, Wayne N6KR > On Jun 24, 2018, at 4:53 PM, Jim Brown wrote: > > While setting up for a grid expedition next weekend, I fear that W6GJB and I > may have blown up the front end of my KX3 -- transmitted 1kW FT8 into a Yagi > within 100 ft of the antenna connected to the KX3.

[Elecraft] KX3 Tech Question
While setting up for a grid expedition next weekend, I fear that W6GJB and I may have blown up the front end of my KX3 -- transmitted 1kW FT8 into a Yagi within 100 ft of the antenna connected to the KX3. Prior to that, I had a screen full of JA decodes on 6M, but after, I had none. Returning from FD, I put the KX3 into an old HP generator of unknown calibration, and, for comparison, also fed the RX in of my K3. 50uv at 50.09 MHz gave S9 on the K3, but only S5 on the KX3 with the preamp off and 5 dB over S9 with the preamp on. I can clearly hear the preamp turning on and I could hear -143 dBm (the lowest level to which I can set the generator). So, the question is, is this "normal?" Is it possible that a protection diode has fried? This is major physical effort for the four guys carrying a complete station up a 3 mile trail that gains 1,000 ft, so I want to make certain that they're taking a good radio. :) 73, Jim K9YC __ 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] K3S HI SIGNAL
The internal band-pass filters are very narrowbanded and very high Q. I believe John was referring to external band-pass filters of the type used in multi-transmitter stations that may be operating at high power into antennas in each other’s near-fields. The K3S and K3 can survive a lot of abuse of this type; it includes built-in signal detection and shut-down of various RX stages. But pumping many watts into the front end (due to tight antenna coupling) is never a good idea. 73, Wayne N6KR > On Jun 24, 2018, at 4:10 PM, donov...@starpower.net wrote: > > The K3 and K3S have built in transmit and receive bandpass filters. > Unfortunately their performance data is unpublished. > > > > http://elecraft.com/manual/K3_Schematics_Jun_2010.pdf > See the third page > > > > David hasn't shared what the specific circumstances may have > caused the HI SIGNAL response.

[Elecraft] Field Day Report
A large group gathered for the K6SRA 3A/SCV FD operation in San Jose. Despite temperatures in the mid-90’s and blistering sunshine, we had many visitors, including a lot of curious non-hams. This tends to be a social event with lots of conversation and ad-hoc experimentation with radios and antennas, so I won’t be bragging about our claimed Field Day score. Still, a good time was had by all, with vast quantities of water and other liquids consumed to avoid heat stroke. Late Saturday afternoon I undertook a brief solo trek to exercise the KX2. I had intended to climb a nearby hill. Given the outrageous temperatures, I settled for a picnic table on the other side of the parking lot, beneath a large oak. Normally I would have tossed a wire into this tree. Instead I used a prototype 2-band, 4’ whip, in keeping with the “two QSOs per foot challenge” we proposed in a recent Elecraft newsletter. I made 10 QSOs over the course of about 20 minutes (that’s 3.00 Q/ft, for those keeping score), ranging from KH6 to the East Coast. Overall, conditions were not thrilling. 20 meters was pretty much single-hop until Saturday evening. 15 m was deceased until this morning when, back at the home QTH, I noticed things picking up on this band around the same time as some sporadic-E kicking in on 6 m.

[Elecraft] KPA500 and KAT500 with KX3
With the KPA1500 about to arrive (Yay!) the question is what to do with the KPA500 / KAT500. In my circumstances it would make sense to have them driven by a KX3. I understand 12 watts out of the KX3 will get me 200 to 250 out of the amp. The question, though, is how to get the greatest degree of integration among the three. I suspect others have done this – anyone able to help me with a tutorial on it?

[Elecraft] K3s won't go into transmit
Hi guys, I think I may have either misconnected something or blown the PTT line after re-connecting my K3s from stand-alone Field Day mode back to being integrated into my main shack using MK-II hardware. I cannot assert PTT to the radio via any means except manually using the XMIT/tune button or CW keying via the paddle. My footswitch, handswitch and MicroKeyer-II PTT controls are all inactive, and I'm in a bit of a panic since I know I didn't change any wiring; I just disconnected everything to bring it outside yesterday. Any ideas where I can start to look? For any of you MK-II users, I have the MK-PTT IN line going to the KEY OUT jack, and the wire marked PTT-IN going to the PTT-IN jack. The MK-II will put the radio into transmit for CW, but not for RTTY, voice keying or any digital mode. I'm beginning to think I may have damaged the radio at this point and could urgently use some assistance.

[Elecraft] How to change K3 COM port to a high number (to avoid N1MM/u2R problem)
Doesn't the MicroHAM router control the com ports? You should be able to set it to anything you want in the router. I have had no issues using Com 1, 2 and 3 with Writelog. John KK9A K7TV wrote: I run two K3 radios with MicroHAM u2R for SO2R in N1MMplus. It has been working, but occasionally I get a message about COM port conflicts, about the two COM ports that are used to control the radios, and this causes problems during a contest such as tomorrow I have spent some time looking for the source of conflict, but don't see those two COM port numbers used by anything else in Device Manager, even when using "show hidden devices". When I set up everything related to N1MM, and the u2R I totally avoided using those two COM ports that are used for the radios. I never get the errors when just running the radios without N1MM/u2R. I don't remember any such error from long ago when I was using N1MM without SO2R. I sought advice on a computer forum and a Microsoft employee advised me to try using high port numbers such as 25 or higher for my applications, as any "hidden" usage in Windows would be unlikely to use a high number. No conflicts are reported for the numbers I use for N1MM and u2R, so it seems meaningless to change those to high numbers. It seems I need to try high COM port numbers for communicating with the radios. How can I do that? Using the Elecraft FTDI adapters.

Re: [Elecraft] Transverter calibration
G'day, Another data point to add. Apologies for it being a bit long. My K3 is fitted with the line up REFLOCK, EXTREF (10MHz GPSDO) and KTCXO-3 +/-1ppm. In the past I have done several warm up runs from cold start to to T+4 hours where for all practical purposes KTCXO-3 drift as measured by the EXTREF module stopped. The results are repeatable with small variations, cold start temperature and room temperature were a reasonably consistent, +23C. Front panel temperature change gives a reasonable indication of the warm up environment of the KTCXO-3. My KTCXO-3 at power up starts at 49.379.836 on average and after warm up stops drifting at 49.379.890. It goes through two plateaux phases the first at T+5 minutes (49.379.863) until T+26 minutes (49.379.865). It then starts a slow rise to T+120 where after it enters the second plateaux (49.379.884) where after there is little change. This is repeatable. However, it must be noted that this is my KTCXO-3 other units will have their own characteristic, even drifting in the opposite direction. I was unable to programme my GPSDO for both 10MHz and 145.5MHz outputs, maybe a forbidden combination, must get to grips with this. So I decided to do a run with a sniff of the 145.5MHz signal fed into the 2m input and the K3 not locked to an external source. The manual REFCAL setting was at the top end of the drift range (49.379.886). After cold start and a quick tune to the 145.500.000 signal the initial dial reading had to be set 176Hz high. There after retune took place for the first hour at one minute intervals and the dial error recorded. Retune was accomplished by offsetting the dial slightly LF and netting with TAP SPOT. There is a small 3Hz difference between netting from LF or HF using this method so for consistency LF was always used. The change in dial reading was consistent with the previously measured warm up drift characteristic of my KTCXO-3: T+1 +176Hz T+5 +98Hz T+28 +86Hz T+60 +17Hz T+80 +11Hz T+100 +9Hz T+120 +8Hz T+180 +4Hz T+240 +1Hz At T+240 the manually set REFCAL frequency and the true drifting frequency of the KTCXO-3 will have converged. The dial frequency and the signal frequency has also essentially converged. When I figure out how to programme two frequencies out of my GPSDO or find a suitably stable 2m source it will be interesting to run the same test with my K3 EXTREF locked. There is great faith placed in digital displays to tell the truth, however, there are factors at play which can render this truth to be a little coloured. Any radio with a free running reference oscillator for example will be in error at some point. I standby to be shot down.

I do have the REFLOCK, EXTREF (10MHz GPSDO) and KTCXO-1; nothing left to add. You are correct that you can’t adjust the offset once you’re in this configuration. As I say, for me its “only” about 50Hz but its consistent. I was gonna have to Elecraft team look at it in their lab the next time I send the rig in (if I send it in). Aside from that I’m living with the 50Hz delta.
