M20 PLT OVERSHOOTS RWY 4 AT HOU WHILE HAVING COM PROBS; THIS RESULTS IN EVASIVE ACTION BEING TAKEN TO AVOID A CONFLICT.

Narrative

ON SUNDAY I FLEW FROM ADDISON ARPT IN THE DALLAS AREA TO HOUSTON HOBBY. BEFORE DEPARTING ADS I REQUESTED VFR FLT FOLLOWING INTO THE HOBBY ARPT HOU. APPROX 5 MI FROM THE HOUSTON CLASS B AIRSPACE I WAS TOLD TO REMAIN CLR OF THE CLASS B AIRSPACE. I MADE A TURN TO HDG 270 DEGS AND REMAINED CLR OF THE CLASS B AS PER ATC REQUEST. I WAS TOLD BY ATC TO 'STAND BY.' AFTER NOT HEARING BACK FROM ATC FOR A CONSIDERABLE AMOUNT OF TIME I CALLED AGAIN AND REQUESTED SVC TO HOBBY AS PER MY VFR FLT FOLLOWING REQUEST. AGAIN I WAS TOLD TO 'STAND BY' AND APPROX 5 MINS LATER HAD STILL NOT HEARD BACK FROM ATC. ON MY THIRD CALL TO ATC I TOLD THEM THAT I WAS NEW TO THE AREA AND THAT I WAS BECOMING UNSURE OF MY POS? I FINALLY RECEIVED VECTORS AND CLASS B CLRNC TO HOBBY ARPT. APPROX 5 MI FROM THE ARPT ATC REQUESTED THAT I MAKE A TIGHT 1 MI L BASE LEG FOR RWY 4. I FOUND THIS TO BE AN UNUSUAL REQUEST SINCE I HAD MADE IT CLR TO ATC THAT I WAS NEW TO THE AREA. I DID NEVERTHELESS CONFIRM THE REQUEST. UPON NEARING THE FINAL APCH PATH TO RWY 4 I CONTACTED HOBBY TWR AND WAS CLRED TO LAND ON RWY 4. MY VERY NEXT XMISSION TO TWR WAS THAT I WAS NEW TO THE AREA AND I NEEDED CONFIRMATION THAT I WAS INDEED ON A CORRECT BASE LEG FOR RWY 4. THE REASON FOR THIS REQUEST WAS THAT UPON GETTING A VISUAL OF ALL THE DIFFERENT RWYS AT HOBBY (6 DIFFERENT RWYS) I FELT A LITTLE UNSURE OF MY POS AND I DID NOT WANT TO TAKE ANY CHANCES AS TO WHETHER I WAS INDEED ALIGNING WITH THE CORRECT RWY. I RECEIVED 'NO RESPONSE' FROM HOBBY TWR? AND AFTER SEVERAL ATTEMPTS TO MAKE CONTACT REALIZED THAT I MUST BE HAVING A PROB WITH MY RADIO? DURING THE PROCESS OF PROB SOLVING AND SWITCHING TO MY SECOND RADIO I REALIZED THAT I HAD PASSED THE FINAL APCH PATH FOR RWY 4. SINCE I HAD ALREADY BEEN CLRED TO LAND I MADE A SLOW R TURN BACK TO THE FINAL FOR RWY 4. ABOUT 3/4 WAY THROUGH MY TURN I RESOLVED MY COM ISSUE BY DIALING IN TWR FREQ ON MY SECOND COM RADIO. AFTER REESTABLISHING COMS I ADVISED TWR THAT I HAD RWY 4 IN SIGHT AND I HAD ANOTHER ACFT IN FRONT OF ME AND WAS NOW #2 FOR LNDG. TWR CONFIRMED I WAS #2 FOR LNDG AND I WAS CLRED TO LAND. TWR INFORMED ME THAT EVASIVE ACTION WAS TAKEN THROUGH COM BY TWR AND THE OTHER ACFT ON FINAL APCH. THIS WAS DONE IN ORDER TO PREVENT A CONFLICT BTWN MYSELF AND THE ACFT ON FINAL APCH. UPON DISCUSSING THIS SITUATION WITH AN ATC SUPVR ON THE GND; I WAS TOLD BY HIM THAT A POTENTIALLY SERIOUS SITUATION WAS AVOIDED AND HE TOLD ME THAT I SHOULD BE MORE PREPARED WHEN COMING INTO A NEW AREA ESPECIALLY A LARGE ARPT LIKE HOU. I ALSO TOLD THE ATC SUPVR THAT I FELT DISAPPOINTED BY THE ATC SVC THAT I HAD RECEIVED AS A VFR PLT THAT WAS IN THE SYS ON FLT FOLLOWING AND THAT I WAS NEW TO THE AREA AND HAD MADE THAT CLR TO ATC. HE TOLD ME THAT THEY HAD GOT UNUSUALLY BUSY FOR A SUNDAY MORNING AND THE PUSH LASTED APPROX 1 HR. THE REQUEST BY ATC TO KEEP A TIGHT BASE LEG TO RWY 4 TOGETHER WITH MY RADIO FAILURE WERE CONTRIBUTING FACTORS TOWARDS MY DEV FROM A NORMAL PROC APCH TO LAND. AS A VFR PLT INTO THE HOU AREA I FELT THAT I DID NOT RECEIVE THE ATTN THAT I DESERVED. ESPECIALLY SINCE I HAD MADE IT CLR THAT I WAS IN UNFAMILIAR TERRITORY. I FEEL THAT IN ORDER TO INCREASE THE LEVEL OF SAFETY STANDARDS THAT CLOSER ATTN SHOULD BE PAID TO VFR PLTS FLYING IN TO LARGER ARPTS.
