Re: [Elecraft] Upgraded K3 synthesizer module now available: The KSYN3A
Hi Wayne Wowa major upgrade, my two cents... a must have, TX phase noise is the most annoying side effect in ham bands today, major advantage in SO2R's configs. Wayne a quick question, are in stock? Waiting times? Some preliminary measurements eventually some side-by-side numbers?

Re: [Elecraft] Upgraded K3 synthesizer module now available: The KSYN3A
The extension of operation to 100-KHz is a terrific addition for those of us using the 600m band. FCC approval for experimental licensed stations on 472-478 KHz has seen a major move of activity to this new sub-band which left users of the K3 out (the old lower limit of 490-KHz). I will have to save up as I have the KRX3, so the cost is double. Also will be interesting to see if the lower phase noise will improve weak-signal detection threshold on digital modes (e.g. JT65). 73, Ed - KL7UW http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: dubus...@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
[Elecraft] Upgraded K3 synthesizer module now available: The KSYN3A
Hello Wayne, It is good to see improvement in RX phase noise which will affect the reciprocal noise mixing. Could you put the improvement in layman terms? For example, in the original KSYN3, a weak CW signal could be heard 10Khz away from a S9+60db signal, under the new KSYN3A, what improvement can I expect? Will it be now heard 1Khz away from the S9+60db signal?

I suspect that the massive improvement they are citing may be simply in comparison to their own previous products, and with the Yaesu products, which tested even worse. 73, Jim K9YC __ 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] Upgraded K3 synthesizer module now available: The KSYN3A
The KSYN3A synthesizer module for the K3 is a completely new design that improves on the original KSYN3 in several ways. All K3s shipped on or after January 23, 2015 already include the new synthesizer (serial number 8801 and later). See feature list below. Ordering and installation instructions can be found here: http://www.elecraft.com/order_form_parts.htm#K3%20Parts * * * NOTE: If you wish to upgrade a K3 that includes the sub receiver (KRX3), you'll need two (2) KSYN3A modules, since the synthesizers for both receivers must be of the same type. * * * KSYN3A FEATURES: * FASTER CW BREAK-IN AND MORE ACCURATE CW TIMING A dedicated coprocessor on the module permits faster transmit/receive switching, improving CW timing accuracy with both internal and external keying. This also speeds up receive recovery between elements. * ULTRA-LOW PHASE NOISE The KSYN3A significantly improves the K3's already excellent receive and transmit phase noise characteristics at close carrier spacings. This, in turn, improves its close-spaced receive dynamic range, yielding even better weak signal detection in the presence of strong signals. In transmit mode, the KSYN3A keeps the signal exceptionally clean, further enhancing K3 performance at multi-transmitter stations, Field Day and DXpeditions. * 600-METER COVERAGE The new synthesizer provides complete coverage of 600 meters -- and below. VFO tuning extends down to 100 kHz, with sensitivity gradually falling off below 450 kHz. Receive sensitivity (MDS) at 475 kHz is typically -120 dBm at the RX ANT IN jack. Transmit output of about 1.0 mW is available for use with a suitable external amplifier. (Note: 600-m allocations vary by country. Operation on this band requires the KBPF3 and KXV3 options. For receive-only use, an antenna can be connected to the RX ANT IN jack on the KXV3 module. For transceive operation with an external amplifier, use the XVTR IN and XVTR OUT jacks, and set CONFIG:KXV3 to TEST.) * EXCELLENT MECHANICAL STABILITY The KSYN3A is virtually immune to both physical vibration and magnetic coupling, and operates over a very wide temperature range with no change in performance.
