Lance Having tried the K3 with the high spec oscillator and with the external locking I found I needed the external locking for my 144 digimode qsos. However my eme shack varies between around 37F and 110F (outdoor garage) so it is expecting a lot of the internal reference
External locking of the K3 also helped when using the internal transverter to drive external transverters at 144MHz for 1296, 2304 and 3400 digital EME qsos If you lock the k3 reference and the 144 xverter inside the K3 it is vital to do the mod at http://www.elecraft.com/K3/mods/K3EXREF%20freq%20shift%20fix.pdf Not sure if the "Production phase-in is pending." Mentioned on the web site has happened yet Dave WW2R From: "Lance Collister, W7GJ" <w...@q.com> To: Elecraft Mailing List <elecraft@mailman.qth.net> Subject: [Elecraft] K3 with 2m module K144XV Message-ID: <511cfb2f.3060...@q.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed I need some guidance. I have a K3 with the optional high stability reference oscillator option. I have been very pleased with the frequency stability of the unit up through 6m. Next month I am interested in ordering the K144XV so I can also use the rig for 2m EME with JT65B mode. Is there anyone out there currently using such a setup successfully on 2m EME? Is it stable enough as-is, or will I need to also add the K3EXREF and some additional outboard frequency standard? I would like to avoid involvement with the K3EXREF unless it is required. I do not plan to use the K3 2m as an IF for microwave transverters, so I hope it will be stable enough on 2m without it. I look forward to your experience!
