BG7TBL also makes a matching 8 output sinewave distribution amplifier. It also contains another Morion 10 MHz OCXO which switches in automatically if the 10 MHz input to the distribution amp is not there. You can usually get a good deal on the GPS reference and the distribution amp together on

I see both a sine wave and a square wave version available on ebay. The K3EXREF doc references both w/ regard to signal source, so I assume either would work. Initially, I'll only be connecting a K3, is one a better choice than the other? Jeff KC9WSJ On 10/31/2015 01:40 PM, Bob W7AVK wrote: >

I may be in need of providing a 10 MHz reference clock to my K3. I know I’d need to purchase the K3EXREF board for this. Without having to cobble together (I’m not a good “cobbler” of shoes or stuff) too much unless it comes in a kit, what are folks using that could be had for relatively low

Yes, I bought one as well, along with the matching 8 channel distribution amplifier which is equally well made. There is a review by VK2XAX Tim Tuck of a later model which may have fixed that tiny error in phase. I also read an interesting article about the 5MHz leakage from the Morion

Ron, The MV89A is pretty incredible-- especially for the price. I think two statements in your posting contradict each other though. It isn't basically "on frequency" from a cold start. It drifts 10's of Hz until the oven temp and oscillator stabilizes. The second statement about taking 40
