Well Barry I really screwed an auction up on a buy it now I am not sure what
really happened but I bought a receiver and I wanted to put a 500.00 bid but hit
buy it now and not sure how it was the National military 1490 and it doesn't'
work what a mess I contracted the sell right away I have delt with this seller
before I hope he lets me out what a blundering mistake .
