Re: [Elecraft] {K-3} K144XV
My original question was how to monitor 2M on the sub, while using the main for HF. I don' seem to be able to do that. Phil K8MBY The K3 with K144XV supports simultaneous 2m reception on Main and Sub. I just verified it with my radio. Set the Main rx to 2m, and then in BSET, tap ANT so MAIN appears. 73, Lyle KK7P Thanks to all who replied, several said 2 meter recption is not possible on the sub. I thought it was, Yes on both the main and sub. __ 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 will require some additional hardware (not yet available), that will allow the sub RX to have a different RF path from the transverter. Wayne alluded to this last December. It is planned, however- just not available right now. (my understanding). Right now, you can have the main and sub on 2M (or any other transverter band), or the main on a transverter band and the sub on HF, via it's own Aux RF input BNC. Hope this helps answer your question.

Re: [Elecraft] {K-3} K144XV
My last attempt didn't make it through, hopefully this one will. Hi all, As I understand it, the only input path to the K144XV is it's dedicated ANT 3 BNC connector, it cannot receive signals through the ATU. The only way the sub receiver can listen to it is if it is sharing the main receiver's antenna connection and hearing the 28MHz IF through the KXV3A. Otherwise 2 K144XVs would be required. The sub receiver can be set to MAIN to share the main receiver's signal or AUX which depending on how it was hooked up when installed will either be the non-transmitting jack on the ATU (CONFIG:KRX3 set to ANT=ATU) or the AUX RF BNC connector on the rear panel (CONFIG:KRX3 set to ANT=BNC), neither of which will hear the K144XV. With the sub turned on go into BSET and tap ANT to change it's antenna to MAIN. Holding RX ANT will also change the sub's antenna when not in BSET. Thus, 2M diversity reception is not possible with the K144XV. I have the sub RX but don't have the K144XV yet (it should arrive any day), so I could be missing something, but I have been studying the manuals in preparation. I'm sure someone will correct me if I'm wrong. Hope that helps.

The datasheet is quite clear - 2m reception is possible on main and
sub-receivers.
Diversity reception is not, because there's only one 2m antenna connection.

Re: [Elecraft] {K-3} K144XV
Well I have the subRX already installed and my K144XV is out for delivery as we speak. I will say that I bought FM filters for both receivers cause I wanted to be able to do full HF use on VFO A while monitoring a repeater or scanning several on VFO B. If that's not already possible I was really led to believe so by the documentation and some others that I spoke with on the phone when I placed my original order. If that's not the case its not the end of the world but id have bought the general coverage receive rather than the second FM filter.

Re: [Elecraft] {K-3} K144XV
It sounds like the sub can be on 2m, but only if the main is as well and they are sharing the KXV3A input path. In that case the main and sub could be on different 2m frequencies, but must both use the antenna connected to the K144XV. Unless something hasn't been implemented yet.

Re: [Elecraft] {K-3} K144XV
Like has been mentioned before it looks like you can only have the sub on 2M if both RX paths are tied to the same antenna port (meaning that the MainRX is on 2M along with the SubRX). It also states in the datasheet that if you have the sub receiver installed that you can tune HF-6M with the Sub wile operating on 2M with the main RX. I really wish there was a way for me to swap that. I'd like to be able to use my big knob to work HF and then when I'm not using the sub on HF I could use it to monitor some of the local repeaters. At the moment if I was wanting to monitor some local repeaters then I'd have to use the VFO B knob to do my HF operation. Which is a bit less than optimal. It does look like there are some extra ports on the 2M transverter. Maybe soon we'll figure out a way to be able to use those. I swear I remember asking someone if I could monitor repeaters on the SubRX while using the main for HF-6M use when I was ordering and was told that would be totally fine... Anyway my K144XV is sitting on the porch right now. I'm still excited to go home and get it installed! Its like most Elecraft products I've had. Its not exactly what I want at the moment but I'll figure out a work around for now to get close to what I want and it will probably be perfect if I just wait a little bit longer... ~Brett (KC7OTG) On Fri, Mar 19, 2010 at 12:25 PM, Bob Cunnings bob.cunni...@gmail.com wrote: Why does the data sheet for the K144XV state 2-meter receive on both main and sub receivers and With the sub receiver installed, you can listen to a repeater’s input and output frequencies simultaneously. http://www.elecraft.com/manual/K144XV%20Data%20Sheet%20rev%204sm.pdf Bob NW8L On Fri, Mar 19, 2010 at 12:13 PM, Phillip Buckholdt k8mb...@wadsnet.com wrote: Thanks to all who replied, several said 2 meter recption is not possible on the sub.

Re: [Elecraft] [K3] Elecraft[K-3] K144XV
I can not see any reference to noise figure in the brochure. Just MDS and FM sensitivity with no bandwidth. When I get mine I will measure the noise figure on a test set. It is likely to be under 2dB and I will use a low ENR head! I suspect like the XV144, the K144XV will need some gain reduction for use with a masthead pre-amp. Signals at the antenna of -30 dBm are not unknown around here resulting in milliwatts at the mixer but the time you add in 20 dB of preamp plus another 20dB of conversion gain. I am still worried about the diode switching, 2m specific PTT outputs and delays. I assume the usual 20mS delay option is there in the menu like all the other bands. This is not quite long enough when you are sequencing an amplifier and a pre-amp as there is more to switch than just the coaxial relays. When used as an IF for microwaves it will need even longer to allow a waveguide switch to operate but this will be mitigated by the split TX/RX outputs and the low power 2m interface. Where does this come out?

Re: [Elecraft] [K3] Elecraft[K-3] K144XV
David, Wayne said: It's actually more like -144 dBm (500-Hz bandwidth). I assume that this refers to a K144XV installed in a K3. This equates to a noise figure of 3db. To achieve a lower noise figure, the gain used in the K144XV would have to be greater, which would further reduce the overall dynamic range (IMDDR3) of the K3 assembly on 2m. 73, Geoff GM4ESD David Pratt wrote on Friday, January 08, 2010 at 9:34 AM In a recent message, AD6XY m.j.wil...@rl.ac.uk wrote ...

Re: [Elecraft] [K3] Elecraft[K-3] K144XV
I know this - so does everyone. I have actually read the manual. However, there is only one TX inhibit and it is shared with the K3 on signal, which I happen to be using. Even if I was not using it the inhibit might easily be set to the default K3 ON and be ignored. Perhaps one of the DIGOUT lines could be used, but it would be better to have a longer delay and a seperate 2m PTT output.

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 ?

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
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 ?

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.
