Narrative:
While in cruise, the rented plane I was flying lost the ability to transmit on either communication frequency. I was however able to listen. Over a distance of 80 mi multiple attempts were unsuccessful in getting a response from center, previous center frequency, other planes known to be on frequency. When it came time for descent I squawked XXXX on transponder instead of proper frequency of xyxx. Emergency squawk codes are very infrequently used therefore they should be written somewhere in plane for easy reference. Also, this problem could have been averted had center attempted to communicate with me. I could have used the transponder had they asked me. To my knowledge they called me only once to ask flight conditions, and gave no indication they did not receive my reply.

Title: LIGHT ACFT ON IFR PLAN LOOSES ABILITY TO TRANSMIT, APPLIES HIJACK CODE INSTEAD OF LOST COM CODE.
Narrative: WHILE IN CRUISE, THE RENTED PLANE I WAS FLYING LOST THE ABILITY TO XMIT ON EITHER COM FREQ. I WAS HOWEVER ABLE TO LISTEN. OVER A DISTANCE OF 80 MI MULTIPLE ATTEMPTS WERE UNSUCCESSFUL IN GETTING A RESPONSE FROM CENTER, PREVIOUS CENTER FREQ, OTHER PLANES KNOWN TO BE ON FREQ. WHEN IT CAME TIME FOR DSCNT I SQUAWKED XXXX ON XPONDER INSTEAD OF PROPER FREQ OF XYXX. EMER SQUAWK CODES ARE VERY INFREQUENTLY USED THEREFORE THEY SHOULD BE WRITTEN SOMEWHERE IN PLANE FOR EASY REFERENCE. ALSO, THIS PROBLEM COULD HAVE BEEN AVERTED HAD CENTER ATTEMPTED TO COMMUNICATE WITH ME. I COULD HAVE USED THE TRANSPONDER HAD THEY ASKED ME. TO MY KNOWLEDGE THEY CALLED ME ONLY ONCE TO ASK FLT CONDITIONS, AND GAVE NO INDICATION THEY DID NOT RECEIVE MY REPLY.
