Re: [Elecraft] [K3] XV144 fault (offset problem?)
Dave, Look at the crystal frequency. If it is 116.000 MHz, then yours is OK. OTOH, if it is 116.010 MHz, then you need to install the mod. The bypass capacitors on the 5 volt regulator are applicable to any XV144. 73, Don W3FPR On 2/8/2011 3:33 AM, David Ferrington, M0XDF wrote: > Yes Don, I have an XV144 kit, not built yet, purchased with the K3, and > delivered in Dec 2007 - I thought it had a serial number, but I haven't built > it yet :-( > > So, based on it's ship date, can you tell me if my XV144 would be subject to > this mod, or perhaps based on the Crystal in the kit > > I'm guessing from the date of publication that the mod for L19 and the Bypass > Capacitors probably does apply to my XV144. > 73 de M0XDF, K3 #174, P3 #108 __ 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

Yes Don, I have an XV144 kit, not built yet, purchased with the K3, and delivered in Dec 2007 - I thought it had a serial number, but I haven't built it yet :-( So, based on it's ship date, can you tell me if my XV144 would be subject to this mod, or perhaps based on the Crystal in the kit I'm guessing from the date of publication that the mod for L19 and the Bypass Capacitors probably does apply to my XV144. 73 de M0XDF, K3 #174, P3 #108 -- Sometimes I think we're alone in the universe, and sometimes I think we're not.

Re: [Elecraft] [K3] XV144 fault (offset problem?)
Don I have to say this has taken a good while to sort out, I sent an email to Gary on 19/04/2010 notifying him of the problem. The response then was to send a couple of new crystals also on the wrong frequency so I gave up and purchased a crystal locally. I have to say the transverter works fine now but I wish it had been sorted out a lot earlier. Roger VK3ADE.

Yes, this mod adds an adjustable coil to move the newer XV144 crystals within the +/- 9.9 kHz calibration range of the K3. In most cases it will pull the crystal far enough to use an offset of zero, but that is not guaranteed in all cases. There is a place already on the XV144 PCB for this part.

Re: [Elecraft] [K3] XV144 fault (offset problem?)
Doug The crystals originally supplied by Elecraft for the 2m Transverter were stamped 116.01Mhz so they were always going to be problematic and off frequency. The ones they replaced the originals with were also 116.01MHz and I really don't know why they were sent unless it was a mistake. maybe some one from Elecraft could comment. Given the distance you are off frequency I would suggest you have similar crystals, by memory there was not offset adjustment available to correct for the frequency error. Ireplaced them with a locally sourced crystal of 116.0Mhz and the transverter came up right on frequency. Regards.

Hi Roger, Many thanks for the response, it certainly is very frustrating. I have the Crystal Oven option installed, so would have to take things apart to see the crystal markings. In the manual it says: Y1 Crystal, 116 MHz 5th Overtone Series Resonant (116.000) Did the ones Elecraft sent you have (116.000) stamped on them? (144MHz input = 116MHz LO + 28MHz IF) Was it the accuracy of the Elecraft crystal parts that was questionable, or were the markings/parts wrong? Hopefully Elecraft will check their crystals for the XV144 and comment before I need to start taking things apart.

Re: [Elecraft] [K3] XV144 fault (offset problem?)
Doug Check the frequency stamped on the crystal, mine was the wrong frequency and gave the exact same problem, I requested a new one and it was also the wrong frequency. In the end I obtained a high stability crystal locally and it came up exactly on frequency. I don't know if Elecraft was aware of this but at the time it was very frustrating.

Re: [Elecraft] [K3] XV144 fault (offset problem?)
Hi Doug, The K144XV here had an +850 Hz offset when received. There is about 25Hz of temperature drift as well. Combined, the 875 Hz could be canceled using the offset setting. 12.5 KHz seems excessive, and that's the highest I've heard of. Note: My K144XV is one of the first ones produced (early 2010), and has remained stable (as above) during the last year. Hope this helps. Doesn't sound like it will. 73 and HNY! matt W6NIA On Wed, 29 Dec 2010 08:22:37 -0800 (PST), you wrote: > >Seasons Greetings, >Just finished building my Xmas present (XV144).

[Elecraft] [K3] XV144 fault (offset problem?)
Seasons Greetings, Just finished building my Xmas present (XV144). Initial trials show an offset frequency of +12.5KHz is required to put it on frequency. Unfortunately the K3 XV1 OFS menu only goes up to +9.99KHz leaving the frequency readout 2.51KHz low. I have re-read the manual, but there doesn't seem to be any other method for the additional required offset? Is it normal for the XV144 to require such a large offset? My frequency references are not exact (IC275E, GB3ANG Beacon and several local amateurs). I don't need any high degree of accuracy but ball-park +/- 300Hz would be nice. Any help would be welcome.
