Fellow tron chasers,



I'm having trouble with my SL-70 transponder.  When I turn it on it immediately says FAIL.  When I turn the little knob it displays the individual test results which all say PASS except SYN, RECV, and TRAN; which I'm taking to mean that at least the radio portion has issues.



It still reports the correct altitude to the GPS which I'm taking to mean that the external encoder is OK and the serial connection to the GX60 is OK too.



The attached antenna appears to be intact.



Any recommendations on things to try before I send it in for repair?



Thanks,

Ralph Capen
