I am interested in purchasing your R3P6-J Arrow 6CH 3.8g 72mhz FM Micro Receiver. I do not see any crystals on your web site. What crystals does it use and do you carry them?

Most single-conversion receivers (because they share a common IF frequency) should be pretty much crystal-compatible, physical sizing not withstanding.

However, other factors can mean that one manufacturer's crystals may not operate at exactly the right frequency on another manufacturer's receiver - although with parkflier stuff the fairly broad tuning means that this may not result in significantly reduced range -- but maybe an increased susceptibility to interference from off-channel sources.

In other words -- use the manufacturer's crystal if you can but if you can't, try one and see. Odds are it'll work and if it doesn't then you're less than five bucks out of pocket anyway.

Corona and BlueArrow SINGLE CONVERSION crystals are the same item.

I noticed that you now have TX crystals listed. When do we get the RX crystals?

They are getting done now.
We started this weekend, though our listings collided with a server and domain upgrade so we we pushed back a day or two.
The server and domain are now upgraded and we can continue to list.
It takes some time to list all those pesky little channels and then have them checked.
