sudioz Posted October 6, 2023 Posted October 6, 2023 This is the 75 ohm, square wave external clock for EtherRegen from BG7TBL who is the best known vendor on Aliexpress. It is 75 ohms, square wave and comes with a 12V wall wart. . The BNC cable is 75 ohms from a vendor in Greece, made of Canare wire and is 50 cm, for the etherregen this is sufficient as it needs to stay close. Price of the clock new is 130 USD/200 AUD and the cable new is about 60 AUD. It made a good difference to my system, in making the music sound more analog. I have upgraded to a low phase noise external clock. The thing with these external clocks is they are all of different quality (as measured by phase noise) and hence there is manual effort in measuring and grading individual ones. The one offered here hasn't been measured, as it a low cost one, but for me at least was worth it (was made even better by a Linear Power Supply- note am selling the wall wart it came with and not with a linear power supply). The one I upgraded to is noticeably better but also 5x the price. As far as the cable goes, a similar story. I upgraded to the Aurealis silver BNC at 4x the cost. Can ship via AusPost parcel with no insurance, for $17 Thanks for looking
andre Posted October 6, 2023 Posted October 6, 2023 I have a similar clock - very good. What did you upgrade to?
sudioz Posted October 6, 2023 Author Posted October 6, 2023 Hi, I got a -114 dB at 1Hz individually measured symmetricon ocxo from one of the two vendors on AliExpress who measures each piece individually and provides a test report. These are pulled from 4G mobile towers. A lot cheaper than afterdark which of course comes in a case etc and is new old stock rather than “old stock” and also individually measured. Saw on internet mutec is coming out with a nano ref but still close to 3K , given our currency strength.
