Thanks for everybodys help to clear up the confusion about crystals. I had no idea that there was a difference. Its no big deal really. I only paid 5 bucks for it. I ordered another crystal "single conversion" and it works fine. I could easily switch to 2.4 tomorrow if I wanted to . I like my JR 72 radio because a RCUniverse member was kind enough to gift it to me to help me get started in the hobby. Plus my red flag on my 3 foot antenna looks cooler than y'alls short stubby 2.4 antenna lol.
