[Milsurplus] Looking for Navy radios on facebook marketplace ?

[Nick England]

Any hints on how to search efficiently on Facebook Marketplace?
Entering teletype gives 100s of autos and auto parts
Entering "navy radio" gives me trucks, model planes, and every kind of
radio in existence

I've learned how to narrow searches on eBay, but Marketplace baffles me
(actually Facebook baffles me in general).
