Re: [Elecraft] K1 Tilt Stand ???
When I owned a K1 my tilt stand was a length of 1" flat bar from Home depot bent in a U. It flipped up and just cleared the tuning knob to protect the front panel during transport.

Re: [Elecraft] Options for KX3
I have all the options plus big heat sink and the side handles/cover (purchased after the front got scratched in my day pack. In order of usefulness: Antenna tuner (integrated very well with radio) works well with random length wires when portable. Filter (a must have for field day operation but only used then) Hand mike (even smaller/lighter would be better when portable) never use the up/down buttons. Battery option (only used to extend my portable operating time when my external Lipro battery runs down).

Re: [Elecraft] KX3 on SSB Mobile
I use my KX3/KXPA100 combination mobile in two different cars and suggest the following: 1. Direct DC to the battery with both sides fused at 30 Amps. 2. Have found my old Hustler to be very inefficient. Have tried several other antennas but use a budipole dipole from a fixed most of the time when I want to maximize my signal. 3. For the microphone I have found Elecraft's H3 hand microphone to get good audio reports when adjusted per Elecrafts instructions. 4. One last thing use Cat 5 or 6 shielded cable for the control cable between the KX3 and the amp grounded only at the amp to avoid problems.

[Elecraft] FD K2, K3's KX3
Worked field day this year with my KX3 setup on 80 15 meters. Nice to be able to operate CW Digital SSB simultaneously on the same band with very small antenna separations. Thanks Elecraft for the bata Fixed mode for the PX3, worked well, however I would like to see an adjustment added that would allow a gain/frequency adjustment to make the passband look flatter when one is near the edge of the display I still have a problem with a false peak 600 Hz off frequency on the display in CW mode even after the recommended adjustments.

Re: [Elecraft] PX3 Anomaly
Both of these problems have been reported here. The second problem is better but still exists. On the first with the blip that is offset I use the workaround of operating CW with a reverse offset until they get it fixed. At least there isn't any off set used on field day. John K7JLT Phil Wheeler w...@socal.rr.com wrote: Make sure those (all!) cables are fully inserted, Ted. I've found that to take more push in the case of the KX3 and PX3 than some of my other devices. Phil W7OX On 6/13/15 4:39 PM, Dauer, Edward wrote: Finally got the KX3 – PX3 – KXPA100 system cabled together and on the air today, all of the F/W updated. All OK but for two anomalies, one of them a bit of a nuisance. The PX3 shows a double sharp spike offset from the tuned frequency about 600 and 700 Hz (an eyeball estimate), at about S2. The twin spikes just stay there a fixed offset away from the marker as the rest of the band marches by. (The PX3 is in tracking mode – I haven’t downloaded the beta revision.) Same thing on every band I’ve tried – 10, 15, 20 and 40. Some other symptoms: The small bit of spectrum (about 100 Hz) between the two spikes is devoid of signal – jet black even when the ref level is set so that the rest of the waterfall span is showing blue. The spikes appear in CW mode but not in AM or SSB. They switch sides when I switch cw sidebands – 600 and 700 Hz below center when the KX3 is in CW rev, and the same distance above center when it’s changed back. When the i/Q cable is disconnected at either end, the spikes slowly decline. But with the cable connected and the KX3 power turned off, they are still there on the PX3. The spikes remain at 600 and 700 Hz offset from center regardless of the span setting. Weird. And troubling, because 300 - 600 Hz is a typical XIT offset I use in pileups when the DX isn’t working “up.” Anyone have any ideas? Anyone seen this before? The other glitch is much less trouble. The KX3 setting sometimes switches itself from PA Mode On to PA Mode off. I think I’ve figured it out – if I turn the KXPA100 power off before turning the KX3 off, or if I turn the KX3 on before powering up the amp, the KX3 must be sensing “no amp” and so switching itself back to PA Mode Off. But then when the amp comes on, the KX3 doesn’t sense that and switch back to PA Mode On. An intelligent default choice, maybe. Any way to defeat it?

Re: [Elecraft] PX3 - Remove artifact from I/Q demodulation?
I have the same problem and find it very distracting. I also have found that there are additional false artifacts above and below the vfo frequency that move in sync with any change in vfo frequency. John K7JLT David Patino d...@onitap.com wrote: Howdy All, So on my PX3 I'm seeing the issue listed in the manual as Dip in Spectral Response Close to VFO Frequency. Described as: I/Q demodulation at baseband (used by the PX3 and many SDR applications) may introduce small, very narrow-band amplitude variations in the response close to the carrier. This effect varies with operating mode and usually has no effect on operation. In CW mode the artifact can be moved by switching to CW reverse mode (ALT switch on KX3). Setting RX Shift to 8.0 rather than NOR in the KX3 menu may also vary to location of the artifact. Here's a screen cap of my PX3 with span set to just 2kHz in CW mode. The dip is 600hz above the VFO freq (CW pitch is set to 600Hz). This exaggerates the issue but it's visible at any spans at and below 50khz. http://i.imgur.com/p1i29Ul.jpg Other than just moving it as the manual suggests, anyone know of any way to decrease the dip, or remove it entirely? 73, David N9PBJ __ 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 k7jltex...@gmail.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
