Narrative:
During the flight from ZZZ1 to ZZZ2 in alaska, I was having difficulty with the aircraft radios -- unable to communicate. At times I could receive but not transmit. I decided to alert ATC by using the appropriate transponder code. I inadvertently squawked 7500 instead of 7600 which initiated an intercept from elmendorf AFB. Unable to communicate. The intercept gave no clear direction as to course or deviation. I rocked the wings and proceeded to ZZZ2 while the intercept circled and made several passes by the aircraft. I landed successfully at ZZZ2.

Narrative: DURING THE FLT FROM ZZZ1 TO ZZZ2 IN ALASKA, I WAS HAVING DIFFICULTY WITH THE ACFT RADIOS -- UNABLE TO COMMUNICATE. AT TIMES I COULD RECEIVE BUT NOT XMIT. I DECIDED TO ALERT ATC BY USING THE APPROPRIATE XPONDER CODE. I INADVERTENTLY SQUAWKED 7500 INSTEAD OF 7600 WHICH INITIATED AN INTERCEPT FROM ELMENDORF AFB. UNABLE TO COMMUNICATE. THE INTERCEPT GAVE NO CLR DIRECTION AS TO COURSE OR DEV. I ROCKED THE WINGS AND PROCEEDED TO ZZZ2 WHILE THE INTERCEPT CIRCLED AND MADE SEVERAL PASSES BY THE ACFT. I LANDED SUCCESSFULLY AT ZZZ2.
