Re: [Elecraft] KX3 internal battery problems
Per-Tore, With increasing cycle count, individual cells are showing differences. If you don't charge them individually, these differences are getting bigger, as reflected by the numbers you posted. You mentioned that you verified cell capacity using your charger. At what discharge current? Most probably not at the 1.5A which the KX3 draws when transmitting. While powering my KX3 with 8 internal Eneloop cells and varying output power, I found a total internal resistance of 1.15 Ohms. A single Eneloop cell showed 34mOhm (I have an instrument measuring Ri by applying short discharge current pulses). In total, only 25% of the total Ri comes from the 8 cells. Battery holder and wiring are responsible for 75%. 73, Markus HB9BRJ -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-internal-battery-problems-tp7617201p7617307.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] [K3] SHIFT/WIDTH in DATA A mode
I was able to narrow down the problem. It is related to SYNC DATA (CONFIG:SYNC DT) which forces the same crystal filter to be used for both RX and TX. As long as SYNC DATA is OFF everything works as expected. If SYNC DATA is ON: (1) Toggling between SHIFT/WIDTH and LO/HI CUT is inhibited (2) SHIFT control is inactive (3) LO CUT and HI CUT both act as WIDTH control Am not sure if these limitations are a logical consequence of SYNC DATA ON or an unwanted side-effect. 73, Markus HB9BRJ -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-SHIFT-WIDTH-in-DATA-A-mode-tp7601016p7601025.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
[Elecraft] [K3] SHIFT/WIDTH in DATA A mode
After a long pause I started to operate in PACTOR again. My K3 behaves differently today compared to earlier firmware some years ago. Current FW is MCU 05.14, FPF 01.19, DSP 02.83. In DATA A mode: (1) PITCH shows N/A, in contradiction to the user manual. Seems to be fixed at 1500 Hz. That's fine with me, as I can adjust the mark/space tones in my PACTOR modem accordingly. (2) SHIFT/WIDTH controls are showing a strange behaviour: Based on the green LEDs next to the 2 controls, only LO/HI CUT is available, SHIFT/WIDTH is not. When moving LO/HI cut, filter graphic and VFO B display are both indicating a LO/HI cut, but what effectively happens is a width variation.

Re: [Elecraft] Ultimate compact KX3 carrying case received -- perfect match for radio accessories!
The Think Tank Strobe Stuff is a perfect case for the KX3. However when you put it in a backpack with other items, there is a risk your KX3 will accidentally be switched on by external pressure on the respective switches. I'm trying to prevent this by carefully packing my backpack. Recently, when taking the KX3 out of its case on a summit two hours after leaving home, everything seemed normal. The KX3 was off. When I switched it on I was suprised about the low battery voltage reading because the 8 internal AA eneloop NiMH cells were fully charged in an external charger just a few days earlier and took about 2.2Ah each. The big surprise however came when I wanted to tune my antenna: The display went dead and the KX3 switched itself off. Back at home I confirmed that the NiMH cells were completely discharged and that the KX3 is drawing around 60uA when switched off, which is OK. I prefer not to imagine in detail what might have happened inside my backpack during my two-hour hike, but definitely the 2.2Ah were converted into heat! Fortunately my KX3 seems to have suffered no damage. Has anyone out there found an easy solution to protect the KX3 from being switched on when carried around in a soft case?

Re: [Elecraft] My KX3 Battery Approach
Using 8 internal eneloop cells, I measured battery voltage versus current (as shown on the KX3 display) during RX and different TX pwr levels, created an Excel scatter chart and fitted a linear trend line. The result: 1.15 Ohms, R^2 = 0.95. A single eneloop cell has around 0.035 Ohms of internal resistance (measured with a 4-connector battery DC resistance meter forcing current pulses thru the cell under test). My conclusion: 25% of the 1.15 Ohms are due to the 8 cells, 75% originate in the battery holder and additional wiring.

Re: [Elecraft] K3 voltage under load
When switching my K3 from RX to TX 100W FM, I measured these voltage drops: 0.03V directly at the Astron RS-35M's output 0.25V at an unused output of a WMR RIGrunner, connected to the RS-35M by a 2ft cable 1.00V as indicated by the K3, connected to the RIGrunner by a 4ft cable By cable I mean the type supplied with the K3. Certainly not as good as the 400mV reported by Guy K2AV. Still better than the 1.7V reported by Harris K9RJ. Corresponds to the 700mV reported by Joe W4TV (direct connection, no RIGrunner) Guess the major problem resulting from voltage drop is a reduced efficiency of the KPA3. 73, Markus HB9BRJ -- View this message in context: http://n2.nabble.com/K3-voltage-under-load-tp3010557p3019971.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

Re: [Elecraft] [K3] K3 : no sound from speaker, no rx
Guys, i just completed the initial test and calibration. I hear no sound from the speaker or headphone, the rx shows no s-meter action when i transmit a signal with an other tx. There are no ERR-Messages. The radio ist equipped with the Transverter-Interface, I still have to install the Sub-RX and KPA100. Experienced the same when building my K3 in August 2008. It seems that the AUX-DSP board (used by Sub-RX), when installed during the front panel assembly, blocks the entire system as long as the Sub-RX itself is not installed. Support told me to remove the AUX-DSP board, do the initial tests and only reinstall it before adding the Sub-RX.

Re: [Elecraft] Transmitting low power through the PA
I have recently become interested in the WSPR beacon mode (http://physics.princeton.edu/pulsar/K1JT), which involves transmitting a continuous signal for periods of 2 minutes. At a level of 5W the underside of the K3 gets uncomfortably hot. Since this is the sort of thing you want to leave running all day, I'd prefer the 100W PA with its big heatsink and pair of fans to take most of the strain. Is this possible? Julian, I'm quite active in WSPR and can confirm that the LPA module is getting hot. When I contacted Elecraft, they sent me a procedure to align several bias currents on the LPA board. To get access, you have to remove the KPA3. I realigned the bias currents but did not notice any significant difference in the temperature of the bottom cover. As a workaround, you can set PWR to let's say 15W and reduce the LINE IN (MIC) setting. Playing with PWR and MIC I can reduce my power all the way down to 100mW (measured with an OHR WM-2 QRP wattmeter). And to my surprise my signal was heard 2500km away... 73, Markus -- View this message in context: http://n2.nabble.com/Transmitting-low-power-through-the-PA-tp1299409p2552990.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
