It is two layer and I added an amp with two transformer outputs. I am not going to get in to board selling or shipping to oldBert In a message dated 10/26/2018 1:22:01 PM Eastern Standard Time, aphid1@comcast.net writes: Bert,   That looks like a useful board. Certainly some of the oscillators I'm giving away would fit nicely on it.  Since it looks like a two layer board, a quick check at pcbway.com puts the cost at $.79 apiece at the 100 quantity exclusive of shipping.

Then anyone can order boards directly from them and you do not have to be involved at all. They have good quality ENIG plated boards, great to solder to. You can list other info too. Regards, Mark

I have made a similar board for Morion MV-89, MTI-260 and HP10811. It has regulators for all voltages required (worst case for all types), can lock to an external reference ( ring mixer from Macom/Pulse el cheapo transformers and and diode quartet), LMH6702 buffers), power level indicator for ref, usual Wenzel style diff amp squarer or Linear technology squarer depending on personal preference. It can produce 1pps from the oscillator with either a $1.50 CPLD or TVB's PICDIV.  1pps drives 3V into 50 Ohm. Should be enough for contemporary CMOS. The CPLD has enough resources to lock the OCXO to an external 1pps. That has not been tested, I also have no PICDIV. But there isn't much to it. There is also an SMA for external EFC. The output amplifier can deliver 20 dBm and act optionally as a doubler, 5 to 10 MHz for example. There are 2 harmonic notches with either crystals or toroids. I only had to click together some macros from my library, and since especially the 10811 needs so much space, there was free epoxy, so to say. The board could be sawed to to pieces in principle, if someone should be interested in LMH6702 buffers, mixer, doubler... There is some "air" between the functions.  The subcircuits have I/Os on a 100 mil grid so they can be easily arranged on Vector board. (with a ground plane, please!) Circuits / Gerbers / Altium Designer files are available. I wanted to lock 16 MTI-260s loosely to a common reference and Wilkinson them together to see how far I could come wrt phase noise. I have them already here, but I'll find no time for that in the foreseeable future. That guy who sold the LUCENT KS24361 plug-ins had made me an offer I could not deny. Ask me if you need Lucent spare parts! I was only after the oscillators. My interest has kinda slipped into 1/f noise in baseband and chopper amplifiers.
