Narrative:

ZDV, frequency 127.55 was busy. The controller was constantly talking on our frequency and at least one other. Split frequencys are becoming a problem. Traffic on our frequency cannot hear traffic on another, and as a consequence, we are stepping all over each other. Our flight had requested information from the controller on 127.55 who replied 'standby, get right back to you.' never did. Repeated requests finally got our information. If the controllers are this busy, they have no business working more than 1 frequency. The service we got from ATC on this day was poor. I believe it was because of 1 controller working multiple frequencys and was overloaded.

Original NASA ASRS Text

Title: LGT FLC COMPLAINS THAT ZDV CTLRS ARE OPERATING SPLIT FREQS AND ARE OVERLOADED AS A RESULT.

Narrative: ZDV, FREQ 127.55 WAS BUSY. THE CTLR WAS CONSTANTLY TALKING ON OUR FREQ AND AT LEAST ONE OTHER. SPLIT FREQS ARE BECOMING A PROB. TFC ON OUR FREQ CANNOT HEAR TFC ON ANOTHER, AND AS A CONSEQUENCE, WE ARE STEPPING ALL OVER EACH OTHER. OUR FLT HAD REQUESTED INFO FROM THE CTLR ON 127.55 WHO REPLIED 'STANDBY, GET RIGHT BACK TO YOU.' NEVER DID. REPEATED REQUESTS FINALLY GOT OUR INFO. IF THE CTLRS ARE THIS BUSY, THEY HAVE NO BUSINESS WORKING MORE THAN 1 FREQ. THE SVC WE GOT FROM ATC ON THIS DAY WAS POOR. I BELIEVE IT WAS BECAUSE OF 1 CTLR WORKING MULTIPLE FREQS AND WAS OVERLOADED.
