Re: [Elecraft] Synchronized and stable GPS phase lock for KX3, K3 and XV transverters
A question regarding the DOCXO, double ovenized crystal oscillator to Chuck, W7CS. I'm completely new to this, but after having looked at a few in ebay, I see that they have an input for frequency control. Do you use them as is, or do you calibrate them by setting the control voltage? And how much variation in frequency is typical to achieve with this control voltage, ie how much off frequency can they be if unadjusted?

Re: [Elecraft] Synchronized and stable GPS phase lock for KX3, K3 and XV transverters
GPS stabilized 10 MHz crystal oscillators are really an overkill, to be references for todays transceivers. A good DOCXO, double ovenized crystal oscillator, is more than adequate, some even claiming accuracies of 10 parts to the -11th . I have purchased several, through Internet advertisers, for well under $50, including shipping from Chinese surplus dealers. These are usually American or Russian surplus units, that are being resold through these sources. I've had repeatedly good and fast service from them. Some of these advertise on E-Bay. I also have Thunderbird and HP GPS stabilized units, as well as Rubidium standards, that could be used. I find that their bulk, complexity and extra wiring is cumbersome and unnecessary, for even up to and including my 10 GHz operations. On my K3/10, which I use for a lot of my V/U/ uW xvrtr needs, as an IF xcvr, I even mount an OCXO, dead bug style to the inside of the 'blank' rear panel of the K3/10 (with Goop adhesive), and run it's output to an SMA feed through connector. I can then either use a SMA jumper cable to connect to the EXREF input, or to a power splitter, to also to be used as a 10MHz reference for my xvrtr(s). This certainly makes a very simple and compact solution.

Re: [Elecraft] Synchronized and stable GPS phase lock for KX3, K3 and XV transverters
The newer Trimble Thunderbolt requires +24VDC, but some of the older units on E-Bay, etc. may require +5VDC, +12VDC and -12VDC, which can be obtained from a simple/inexpensive power supply. (I used a Meanwell NET-35B). It outputs a 10MHz sine wave (which plugs into the K3EXREF) as well as 1pps logic signal. Trimble also makes/made an active antenna, which I also found on E-Bay, which is a small square about 2 in/5 cm square and has an internal preamp powered by +5V supplied on the Thunderbolt's antenna jack. I've been running one for about a year now, and it maintains the 10MHz to within about 30 parts per trillion, depending on how many satellites are regularly visible - I usually see 8 or 9 in south Florida and 5-6 in the mountains of western North Carolina. __ 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] Synchronized and stable GPS phase lock for KX3, K3 and XV transverters
Bob The Trimble Thunderbolt is scarce on the used market and when they appear the price is painful. They were designed and manufactured for the BB wireless and cellular market when the industry switched from analog to digital synchronized cell sites. I was part of that out business. We need a compatible module that will work with the Elecraft products. Today there are chips that reduce to complexity and price that would make it possible to have a product that will reach the Elecraft user base of customers. John, W1QS Not that I had a need but I did instal the K3EXREF with a Trimble Thunderbolt GPSDO. So I have the 10MHZ reference available. I also have no present need for the XV144 XV432 to be locked to that external reference. However were a kit available to do it I would purchase the kit/accessory to do so. i would like to see it as a product. 73, Bob K2TK ex KN2TKR (1956) K2TKR __ 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
