I looking to buy crystals for a filter that I will use in a 17m or 40m SSB receiver.

Some EBay listings call out "8MHZ 8.000MHZ 8M Hz Quartz Crystal Oscillators HC-49S" and some just "8.000 MHz 8 MHz Crystal HC-49/S"

The first one says "crystal oscillator" and the second just "crystal"

Is the first one also just a crystal  since they are both 2 lead devices?

Am I confused or is there a difference between the 2?

Or are they using confused terminology because it can be used as an oscillator?

A two lead device in a HC-49S case would most likely be s crystal and not an oscillator.  Most of those ads do add the word "passive" to the description, which is another clue that these just crystals.

If you don't mind 10.000MHz, I rescued from the dumpster at work when the place closed down a bag of 500 off 10.0000 MHz HC-49/U crystals. You are welcome to a dozen....if you are going to Hamvention in Ohio next year or have a buddy who is and can collect, you don't even need to worry about postage!

If you want them sooner, I can put them in the mail. Green customs form, value 10c each......would only cost $2 or $3...

Peter
Thanks for your offer but I didn't see your post until today

I had already  bought 100 (10.000 mhz) for $4.86 with shipping from China
