There has been some chatter in the forums about a European country still
making new crystals, through a new company to fill the void, but the
specs are a bit more sloppy than they claim on their website, for
example, 10ppm comes out more like 30ppm. If interested, I can scour my
messages, I'm pretty sure I saved the post.
If original isn't need, there are solid state replacements with a
programmable range of a few hundred MHz, and they are small enough to
fit within many crystal cases. Here is an example:
I haven't tried the device, but it looks promising, and so far all I've
heard are good things.

An accomplished ham, Steve Reed (can't remember his call) recently published an article on these in Electric Radio Magazine wherein he used two of these devices very successfully to replace all of (10) the defective heterodyne oscillator crystals in two pieces of Heathkit gear.The result was little short of spectacular.The devices cost $18.95 each.I, for one, am extremely grateful for his work on these.Ken W7EKBSent via the Samsung Galaxy S21 5G, an AT&T 5G smartphone

Dear Nick
I have one AN/URT-23 but the interconnection cables between the power
supply, power amplifier, exciter and antenna tuner are missing....
I am looking to buy a collection of these cables or only the connectors. If
you can help I would greatly appreciate it.
Thank you very much

I wonder what happened to all ICM's paper when they closed. I seem to think some Canadian bought out the whole place ?
There were schematics i would love to see. Such as their 'modular' receiver and transmitter kits.
ICM also produced a 'model 1500' which was a 'Part 15' CB radio with roof mounted radio equipment. I would really like to
find one of those before i have to exit, but it's not looking good for success.
