If you know someone who purchased a Tracker2 OT2m from us at Dayton, 
please pass this on.

We just discovered that the contract manufacturer installed two 
capacitors incorrectly.  The result is that it requires a fairly high 
audio level to decode anything.  Our test fixture was set just above 
this level so we didn't catch it immediately.

The good news is that there's an easy workaround.  Just put a blob of 
solder on solder jumper SJ2 (near the top left mounting screw) to short 
out the pads.  This gets decode performance back to normal.

Of course, we're happy to fix it here - just contact me off-list for an 
RMA number and return shipping label.  I'll try to track down as many 
customers as I can from their credit card receipts, but there are bound 
to be some cash sales or names that are too common to cross-reference on
