Chuck, You may have read that I am waiting delivery of a new 144/28 transverter from DEMI (maybe this week). It is a prototype dual-receive unit and there is a possibility it will include an ext. ref. locking LO. DEMI is using me as alpha-tester of this transverter so putting a lot of new stuff in it.
I asked to be a beta-tester for the K3 ext. ref. modification, but have not received anything. 73, Ed - KL7UW ------------------------------ Message: 22 Date: Sat, 12 Feb 2011 14:51:03 -0700 From: Chuck Smallhouse <[email protected]> Subject: [Elecraft] 2 M Transverter Stabliization To: [email protected] Message-ID: <[email protected]> Content-Type: text/plain; charset="us-ascii"; format=flowed Wayne, Eric, I'm referring to some concerns described by inputs to the Elecraft Reflector, about not only the stability but also L.O. calibration of the 2 M xvrtr, K144XV and probably the XV144. I wonder if in the near future you might consider phase locking their L.O.s to a 10 MHz OCXO. I understand that there are some Beta units in the field that are locking the K3's TCXO to 10 MHz (when can I get one?). It would also be great if you could do the same for your 2M xvrtrs, so that they could be synched to the same stable source. Many of us VHF/UHF/Microwave weak signal and EME experimenters/operators, are now phase locking (via a 10 MHz source) our xvrtrs to those upper bands, most of which use a 2 M IF. At present I don't believe that there are any other manufactures or vendors doing this yet, for 2 M xvrtrs. It would really be a boon to have a self contained, ultra stable and accurate, 2M IF system the quality of a K3.
