Narrative:

After monitoring ATIS, I called clearance delivery and read back my clearance (correctly). After departure, tower advised me to contact departure. I inadvertently used the published frequency (125.9) instead of the frequency given in my clearance. Departure contacted me and advised to change to the appropriate frequency (118.4). After trying to contact them on my #2 radio (which was garbled), I switched to the #1 radio and contacted them successfully. At this time, departure advised me of the current altimeter setting and I saw an small transport pass underneath me (from left to right) at the distance specified in this report. Departure again contacted me to check the altimeter setting and altitude, and then cleared me out of the TCA (at this time, I was at 5500' MSL). After squawking 1200, departure advised me to copy the phone # for las TRACON. I called them upon arrival in scottsdale, az. My lack of experience in a TCA (this was my first solo departure) and the problems I experienced with my #2 radio contributed to this incident.

Original NASA ASRS Text

Title: AN SMA ON A VFR DEP LOSES SEP WITH AN SMT.

Narrative: AFTER MONITORING ATIS, I CALLED CLRNC DELIVERY AND READ BACK MY CLRNC (CORRECTLY). AFTER DEP, TWR ADVISED ME TO CONTACT DEP. I INADVERTENTLY USED THE PUBLISHED FREQ (125.9) INSTEAD OF THE FREQ GIVEN IN MY CLRNC. DEP CONTACTED ME AND ADVISED TO CHANGE TO THE APPROPRIATE FREQ (118.4). AFTER TRYING TO CONTACT THEM ON MY #2 RADIO (WHICH WAS GARBLED), I SWITCHED TO THE #1 RADIO AND CONTACTED THEM SUCCESSFULLY. AT THIS TIME, DEP ADVISED ME OF THE CURRENT ALTIMETER SETTING AND I SAW AN SMT PASS UNDERNEATH ME (FROM LEFT TO RIGHT) AT THE DISTANCE SPECIFIED IN THIS RPT. DEP AGAIN CONTACTED ME TO CHK THE ALTIMETER SETTING AND ALT, AND THEN CLRED ME OUT OF THE TCA (AT THIS TIME, I WAS AT 5500' MSL). AFTER SQUAWKING 1200, DEP ADVISED ME TO COPY THE PHONE # FOR LAS TRACON. I CALLED THEM UPON ARR IN SCOTTSDALE, AZ. MY LACK OF EXPERIENCE IN A TCA (THIS WAS MY FIRST SOLO DEP) AND THE PROBS I EXPERIENCED WITH MY #2 RADIO CONTRIBUTED TO THIS INCIDENT.
