Hello Glen – your new LO project (LO for any radio) sounds interesting. Any idea of what you will charge for one if you decide to market your work ?

Hi Dick
The cost of parts is about $50 , plus the OCXO/TCXO you decide to use. I am going to put a $38 OCXO on the board, but you can use anything really. The big cost is the surface mount loading, if we make 100, this will be about $25/board I guess. I will do more on the project when I get my next time segment I can spend on it in the next few weeks. 73

I have a few HP-10811D 10MHz oven controlled oscillators one of which could be plugged into your ‘board’ via a cable. This would be a great time-base that your board could ‘discipline’ nicely. Any chance you could include the pin-out for a SMA-like connector on the board ?
It sounds like your board can be purchased for about $75 if one has their own oscillator. I wrote an article in QEX back around 1998 detailing an oven stabilized crystal oscillator that is simple to build and very effective.

I have a HP10811D !
oh yeah it will have a connector or pads or pins of sorts for ‘other oscillators’
cheers
HI Glen. Can you share me your code codec2 on cortex M7? Thanh you very much.
