Narrative:

I was the copilot, PNF, during the second flight of a B737-700 on a test flight. During this flight, checks were completed on nearly all flight deck system. During the descent from 5000 ft to 3000 ft, the alternate flap check was still in progress, prior to the ILS approach, and touch-and-go landing at airport. Prior to the handoff to tower, we were given missed approach instructions, told to maintain 3000 ft and remain 'on, or west of the localizer for traffic.' we were 'cleared for the approach and tower at LOM, 132.95' and I set 132.95 in the #2 VHF standby window. We were cleared for the approach, on a 90 degree intercept from the west. The airplane was configured flaps 1 degree with the captain monitoring HUD operation. The localizer/GS came alive simultaneously and the captain called flaps 5 degrees. I switched to tower and reported LOM inbound for a touch-and-go. The captain called gear down/flaps 15 degrees, and landing checklist. With the 90 degree intercept, and not allowed on overshoot because of traffic, simultaneous localizer/GS capture, flap and gear changes, there was a lot of cockpit chatter along with the tower call. I thought I had made the call to tower (normal side tone) and our flight engineer also heard the tower call and cleared for the touch-and-go. We continued inbound, thinking we had made contact, briefing the nonstandard flaps 15 degree approach, and accomplished the 'too low gear' and 'too low flaps' confign warning checks. We completed the flaps 15 degree touch-and-go landing and climb out, gear and flap cleanup, to the missed approach altitude and began a turn to 210 degrees per instructions. When tower hadn't yet handed us off to center, I flipped the switch back to 128.5 and checked in. They told us that tower had not been able to talk to us and asked if they had given us the new tower frequency of 132.95 and I said they had. The remainder of the flight to ZZZ was uneventful. During crew discussions, following the flight, of why tower did not hear our transmission: 1) we were 'blocked' during transmit on 132.95, and heard only cleared to land for another airplane. 2) this was the only time the #2 VHF was checked on 132.95, and was possibly not functioning on this frequency. 3) the radio control panel 'tfr' switch did not switch for 128.5 to 132.95 when selected, and we were too low for center to hear our transmission and tell us we were on the wrong frequency. 4) the tower's transmit was inhibited, since we did not get a handoff back to center. In the future, to prevent such a hectic time at the OM during a 90 degree intercept, I would recommend we configure to gear down/flaps 15 degrees prior to the intercept. Now, I also position all other audio monitor selectors to a low setting, except #2 VHF, so it's obvious that the only 'normal side tone' can come from the #2 VHF transmit. Supplemental information from acn 452823: it is unclr whether or not the tower acknowledged our report or not. We could hear him talking to other aircraft. He also stated that we had 'blasted through' without a landing clearance. We did not receive any calls from tower asking us to verify that we could hear them.

Title: A B737-700 MAKES A TOUCH-AND-GO LNDG WITHOUT HAVING CLRNC FROM THE TWR TO DO SO AT ZZZ, US.

Narrative: I WAS THE COPLT, PNF, DURING THE SECOND FLT OF A B737-700 ON A TEST FLT. DURING THIS FLT, CHKS WERE COMPLETED ON NEARLY ALL FLT DECK SYS. DURING THE DSCNT FROM 5000 FT TO 3000 FT, THE ALTERNATE FLAP CHK WAS STILL IN PROGRESS, PRIOR TO THE ILS APCH, AND TOUCH-AND-GO LNDG AT ARPT. PRIOR TO THE HDOF TO TWR, WE WERE GIVEN MISSED APCH INSTRUCTIONS, TOLD TO MAINTAIN 3000 FT AND REMAIN 'ON, OR W OF THE LOC FOR TFC.' WE WERE 'CLRED FOR THE APCH AND TWR AT LOM, 132.95' AND I SET 132.95 IN THE #2 VHF STANDBY WINDOW. WE WERE CLRED FOR THE APCH, ON A 90 DEG INTERCEPT FROM THE W. THE AIRPLANE WAS CONFIGURED FLAPS 1 DEG WITH THE CAPT MONITORING HUD OP. THE LOC/GS CAME ALIVE SIMULTANEOUSLY AND THE CAPT CALLED FLAPS 5 DEGS. I SWITCHED TO TWR AND RPTED LOM INBOUND FOR A TOUCH-AND-GO. THE CAPT CALLED GEAR DOWN/FLAPS 15 DEGS, AND LNDG CHKLIST. WITH THE 90 DEG INTERCEPT, AND NOT ALLOWED ON OVERSHOOT BECAUSE OF TFC, SIMULTANEOUS LOC/GS CAPTURE, FLAP AND GEAR CHANGES, THERE WAS A LOT OF COCKPIT CHATTER ALONG WITH THE TWR CALL. I THOUGHT I HAD MADE THE CALL TO TWR (NORMAL SIDE TONE) AND OUR FE ALSO HEARD THE TWR CALL AND CLRED FOR THE TOUCH-AND-GO. WE CONTINUED INBOUND, THINKING WE HAD MADE CONTACT, BRIEFING THE NONSTANDARD FLAPS 15 DEG APCH, AND ACCOMPLISHED THE 'TOO LOW GEAR' AND 'TOO LOW FLAPS' CONFIGN WARNING CHKS. WE COMPLETED THE FLAPS 15 DEG TOUCH-AND-GO LNDG AND CLBOUT, GEAR AND FLAP CLEANUP, TO THE MISSED APCH ALT AND BEGAN A TURN TO 210 DEGS PER INSTRUCTIONS. WHEN TWR HADN'T YET HANDED US OFF TO CTR, I FLIPPED THE SWITCH BACK TO 128.5 AND CHKED IN. THEY TOLD US THAT TWR HAD NOT BEEN ABLE TO TALK TO US AND ASKED IF THEY HAD GIVEN US THE NEW TWR FREQ OF 132.95 AND I SAID THEY HAD. THE REMAINDER OF THE FLT TO ZZZ WAS UNEVENTFUL. DURING CREW DISCUSSIONS, FOLLOWING THE FLT, OF WHY TWR DID NOT HEAR OUR XMISSION: 1) WE WERE 'BLOCKED' DURING XMIT ON 132.95, AND HEARD ONLY CLRED TO LAND FOR ANOTHER AIRPLANE. 2) THIS WAS THE ONLY TIME THE #2 VHF WAS CHKED ON 132.95, AND WAS POSSIBLY NOT FUNCTIONING ON THIS FREQ. 3) THE RADIO CTL PANEL 'TFR' SWITCH DID NOT SWITCH FOR 128.5 TO 132.95 WHEN SELECTED, AND WE WERE TOO LOW FOR CTR TO HEAR OUR XMISSION AND TELL US WE WERE ON THE WRONG FREQ. 4) THE TWR'S XMIT WAS INHIBITED, SINCE WE DID NOT GET A HDOF BACK TO CTR. IN THE FUTURE, TO PREVENT SUCH A HECTIC TIME AT THE OM DURING A 90 DEG INTERCEPT, I WOULD RECOMMEND WE CONFIGURE TO GEAR DOWN/FLAPS 15 DEGS PRIOR TO THE INTERCEPT. NOW, I ALSO POS ALL OTHER AUDIO MONITOR SELECTORS TO A LOW SETTING, EXCEPT #2 VHF, SO IT'S OBVIOUS THAT THE ONLY 'NORMAL SIDE TONE' CAN COME FROM THE #2 VHF XMIT. SUPPLEMENTAL INFO FROM ACN 452823: IT IS UNCLR WHETHER OR NOT THE TWR ACKNOWLEDGED OUR RPT OR NOT. WE COULD HEAR HIM TALKING TO OTHER ACFT. HE ALSO STATED THAT WE HAD 'BLASTED THROUGH' WITHOUT A LNDG CLRNC. WE DID NOT RECEIVE ANY CALLS FROM TWR ASKING US TO VERIFY THAT WE COULD HEAR THEM.
