If the current was about 30 mA without the chip, that's about right.
But you said stayed **above 30 mA** How much above? 40 or 50 mA would be a problem.
What's your power supply voltage? If it's a 13.8 V supply the current will be only a few mA more than what I measured with a 12 V supply.
All indications point to a zapped U1, so go ahead and contact Steve the Kitter for a replacement.
His email contact info is at the bottom of the Bayou Jumper kit page.
While you are waiting for that you can go ahead and check out the transmitter section. It's completely independent of the receiver.
