A B737-700 IN POS AND HOLDING COULD NOT COMMUNICATE WITH SLC TWR WITH #1 VHF COM; BUT ADJACENT ACFT ON GND COULD HEAR AND XMIT TO THE B737-700.

Narrative

WHILE HOLDING IN POS FOR TKOF; WE WERE CLRED FOR TKOF (RWY 16R). WE ACKNOWLEDGED TKOF CLRNC AND BEGAN TO ROLL. AROUND 80 KTS; WE HEARD TWR REPEAT OUR TKOF CLRNC. I ACKNOWLEDGED A SECOND TIME. IT WAS MY FO'S TKOF; AND IMMEDIATELY THEREAFTER MY FO ACKNOWLEDGED THE CLRNC. ONCE AIRBORNE; TWR SAID SOMETHING TO THE EFFECT OF 'ACR XYZ FLT ABC WE HAVE NEVER RECEIVED YOUR ACKNOWLEDGEMENT OF TKOF CLRNC; IF YOU HEAR THIS CONTACT DEP.' AN ACR XXX PLT THEN XMITTED OVER TWR FREQ THAT HE HEARD 'ACR XYZ; ABC ACKNOWLEDGE THE TKOF CLRNC 3 TIMES.' THE POINT OF THIS RPT IS TO ADD THIS INCIDENT TO YOUR DATABASE ON POSSIBLE RADIO BLIND SPOTS FROM 737-700 ACFT. UNLIKE THE SIT ADDRESSED LAST YR IN THE PLT READING FILE BOOK; WE COULD ALWAYS HEAR THE TWR. OBVIOUSLY; ACR XXX FLT XX COULD HEAR OUR XMISSIONS ON RWY 16R; BUT THE TWR COULD NOT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED UNLIKE THE PROBS DESCRIBED IN THE FLC READING FILE ON B737-700 #1 VHF COM; WE COULD ALWAYS HEAR THE TWR. THE RPTR SAID THE OTHER ACFT INCLUDING ACR XXX COULD HEAR THE XMISSIONS AND THE TWR RESPONSE.
