I note that the K144XV firmware update utility mentioned in the docs has not been posted yet. Perhaps the shipment schedule has slipped again. Some word from Wayne or Eric on the shipment status of the K144XV would most welcome.

Re: [Elecraft] Elecraft[K-3] K144XV
Firmware is finished. K144XV PC utility (for loading firmware) is also finished. A small number of units have been shipped and a lot more are about to be. Early reports have been very positive. I suspect some may show up on the reflector any day now. 73, Wayne N6KR On Jan 7, 2010, at 12:39 PM, Bruce Beford wrote: > Phil K8MBY asked: > >> Anyone installed the K144XV yet ? >> Comments > > I asked the same question earlier this week.

Re: [Elecraft] Elecraft[K-3] K144XV
We're shipping K144XVs. :-) There are a lot of early orders as part of a very large backlog. We're working through confirming and shipping those right now. The K144XV specific utility hasn't been posted because there is no need for it yet. We haven't released any firmware updates to the basic 144XV uC itself. (Its much less complex than the maionK3 code and has been very stable. ) The K144XV downloader will actually will be part of K3 Utility under a different tab, since the K144XV is a K3 Option. We have the utility in use internally and are just making sure its ready for prime time before release. It will certainly be released before we release any code updates for the K144XV uC. Most updates for the K144XV operation will be part of the regular K3 firmware, (through normal K3 downloads from K3 Utility) since the overall operation of the K144XV is controlled from the K3's front panel uC. most feature changes will happen there. 73, Eric WA6HHQ Bruce Beford wrote: > Phil K8MBY asked: > > >> Anyone installed the K144XV yet ? >> Comments >> > > I asked the same question earlier this week.

Re: [Elecraft] Elecraft[K-3] K144XV
I am intrigued. Why does the K144XV need any firmware apart from on/off like the XV-144? Can it do other things? I have been meaning to ask for a while, how will it control my 2m PA which is not the same as the HF PA, and will it allow a delay for the relays and pre-amp like the XV144 does? Is there volts up the coax for a pre-amp? Eric Swartz - WA6HHQ, Elecraft wrote: > > > > The K144XV specific utility hasn't been posted because there is no need > for it yet.

Re: [Elecraft] Elecraft[K-3] K144XV
Correction to my posting: Dick, Our download Utility author, just told me we actually will release the K144XV utility as a separate downloader form K3 Utility. that's what we are using now in-house. All my other comments though are correct. ;-) Running too fast this afternoon! 73, Eric Eric Swartz - WA6HHQ, Elecraft wrote: > We're shipping K144XVs. :-) There are a lot of early orders as part of > a very large backlog.

Re: [Elecraft] Elecraft[K-3] K144XV
Thanks, Guys. I appreciate the updates. I am one of those who "ordered early" (within minutes of the page going up). I appreciate the passion you guys (and the whole staff) pour into all the Elecraft products. 73, Bruce N1RX (K1, KX1, K2, K3...

Re: [Elecraft] Elecraft[K-3] K144XV
I installed a production K144XV recently. It's been in K3 #24 for about 10 days, and there haven't been any real issues with it. Mechanical installation went according to plan, and takes about 60 minutes. There is one power pin that needs to be soldered down to a pad on the RF Board to power the module. This step take more time than all the rest. FM / SSB / CW all worked fine with only a minor calibration on the WMTR MW. It's a good step to follow, and it's referred to in the assembly instructions. On the air testing went well, with FM and SSB working first time and no K3 transmit adjustments needed. For most if not all users, adding the K144XV is transparent from the op's point of view. You just added a band to the radio... No hassle operating it. The noise figure is extremely low (1.0 dB or less) with the transverter, so with the K3 using it, it hears quite well. As with the other bands, you can pretty much receive with preamp off and RF GAIN at one or two o'clock. No weirdness on TX either. Just good audio reports like with a normally equipped K3. Sensitivity is better than -125 dBm, and I think the MDS is perhaps 10 dB better than this figure. My signal generator only goes down to -125. At this signal strength, you hear a readily discernable signal (tone in my case). I've worked quite a few stations > 40 miles out with just a 3 element Yagi at 20 feet. And that's using only the 10W provided by the K144XV. 73, matt W6NIA K3 #24 On Thu, 07 Jan 2010 12:54:52 -0500, you wrote: >Anyone installed the K144XV yet ? >Comments > > Phil K8MBY > # 609 >__ >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 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

This has already been added to production RF boards, but those with existing K3s will need to solder the pin in. > Sensitivity is better than -125 dBm, and I think the MDS is perhaps 10 > dB better than this figure It's actually more like -144 dBm (500-Hz bandwidth). Maybe you were referring to FM sensitivity at 10 dB S+N/N? A much wider bandwidth is used in that case.

Maybe you were >referring to FM sensitivity at 10 dB S+N/N? A much wider bandwidth is >used in that case. I was using SSB, 2.8 KHz for this measurement. -125 is the best the old HP8656B can do. At that level, the signal is solid, readily usable. I KNOW the MDS is way down from here, but I couldn't measure it easily. For FM, I didn't try the measurement. I was too busy with "fun with distortion" finagling. If I measure FM sensitivity, what would you expect (er, what did you measure in the lab)? I'll borrow an attentuator and a couple patch cables, and see where I measure the MDS using 500 Hz BW. Want to bet it's within spittin' distance of -144? :) I can repost with these results, but I will clear them with you and/or Eric first. The spec sheet doesn't show MDS. matt > >Wayne >N6KR > > __ 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] Elecraft[K-3] K144XV
If sensitivity is less -140dbm on 2 meters it is DEAF!!!
