Esteemed List Members,
I have four new Midland glass encased 3.00 MHz HC 6 case style available.
Each one was given a S/N and were ordered for Hallicrafters circa. Ovenized
they would be excellent although I don't now what oven temp was specified.
Best guess is 85 C.
I can send world wide

I assume you mean derived from a high quality 10 MHz.
some sort of discrete divide multiply? divide by 5 multiply by 12?
A PLL with VCXO with good far out noise? (sort of like "clean up loops"
Hi Pete,
Speaking from limited experience, I wonder if a garden variety OCXO at say 10
MHz + some CMOS logic to act as a frequency multiplier might not fit the build?
Then again, perhaps 24MHz is a little fast for the logic chips.. not sure.
Hope this helps spark some discussion.
Jim…

If your goal is, as Jim guessed, to get 24MHz from 10MHz and
you are using something like an RTL-SDR, then how about just
passing the 10MHz through a CMOS gate to square it up and
get nic
Access to " the xtal" is not an option the SDR is enclosed in a metal box.
Do a web search for RSP2Pro

It does have an external reference input..
There's not a lot of info on the Mirics data sheets (or on the sdrplay
website)
It sort of looks lik

Hi Pete,
You probably want this...

Lots of VK's are lining up for the first run of boards to lock their radios.

Hi Mark,
this is a product of Glen VK1XX.
he will have a website with eCommerce up soon and when that happens I will
announce it to the list
