Thank you, Greg. Revenue for the quarter grew 8% and was above our guidance with growth in both segments, both regions and all three technologies. APX tailwinds during the quarter were $13 million, while acquisitions added $19 million. GAAP operating earnings were $639 million or 25% of sales, up from 15.7% in the year ago quarter, which had the impact of the $147 million fixed asset impairment charge related to our exit from the ESN contract in the UK.
Non-GAAP operating earnings were $741 million up 10% from the year ago quarter and non-GAAP operating margin was 29%, up 50 basis points, driven by higher sales, lower material costs and improved operating leverage, partially offset by a higher mix of international product shipments and the revenue deferral related to Airwave. GAAP earnings per share was $2.70 up from $1.63 in the year ago quarter, which had the impact of the ESN asset impairment. Non-GAAP EPS was $3.19, up 6% from $3 per share last year.
The growth in EPS was driven by higher sales and margins, partially offset by the Airwave deferral and a higher effective tax rate in the current year. Opex in Q3 was $551 million, up $29 million versus last year, primarily due to acquisitions and higher employee incentives in the current year.
Turning to cash flow. Q3 operating cash flow was $714 million, up $326 million versus last year, and free cash flow was $649 million, up $331 million. Increase in year-over-year cash flow was primarily driven by higher earnings and improved working capital. And with our Q3 year-to-date operating cash flow of $799 million, up significantly from last year, we are solidly on track to deliver on our $1.9 billion of operating cash flow outlook for this year. Capital allocation for Q3 included $147 million in cash dividends, $322 million in share repurchases and $65 million of capex.
Moving to segments. In the Products and SI segment, sales were up 5% versus last year, driven by growth in both LMR and Video. Currency tailwinds were $4 million and revenue from acquisitions in the quarter was $1 million. Operating earnings for the segment were $420 million or 26.1% of sales, up from 24.5% in the prior year, driven by higher sales, lower direct material costs and improved operating leverage, partially offset by mix.
Some notable Q3 wins and achievements in the Products segment include a $75 million P25 device order for a U.S. Federal customer, a $55 million P25 system order for a Southeast Asia customer, a $42 million P25 device order for the Texas Department of Public Safety, a $30 million P25 device order for a U.S. federal customer, a $20 million P25 device order for Indiana State Police and a $3 million fixed video expansion order for a U.S. federal customer.
In Software and Services, revenue was up 12%, inclusive of the Airwave deferral with 31% growth in Command Center and 15% growth in Video. Revenue from acquisitions was $18 million in the quarter, and FX tailwinds were $9 million. Operating earnings in the segment were $321 million, up 7% versus last year and operating margins were 34%, down from 35.7% last year. Excluding the Airwave deferral, operating margins for the segment were up, driven by higher sales and improved operating leverage.
Some notable Q3 highlights in this segment include a $23 million LMR service agreement for a large European customer, a $23 million service agreement for East Bay regional communication systems in California, a $20 million LMR service agreement for the Los Angeles Police Department, a $12 million command center order for Kern County, 911 District in Texas and an $8 million body-worn camera order for the Metro Nashville Police. Looking at our regional results. North America Q3 revenue was $1.8 billion, up 6% on growth in all three technologies. International Q3 revenue was $773 million, up 13% versus last year driven by growth in LMR and Video.
Moving to backlog. Ending backlog was a Q3 record of $14.3 billion, up 6% or $764 million versus last year, inclusive of $321 million of favorable currency rates driven by strong demand in North America. Sequentially, backlog was down $4 million, inclusive of $125 million of unfavorable FX, driven by the revenue recognition of Airwave, partially offset by strong demand in North America.
In Products and SI, ending backlog was up $62 million or 1% versus last year, driven primarily by strong demand in North America. And sequentially, backlog was up $80 million, also driven by strong demand in North America.
In Software and Services, backlog increased $702 million compared to last year, inclusive of $294 million of favorable FX driven by strong demand for multiyear software and services contracts in North America, partially offset by the revenue recognition for Airwave. Sequentially, backlog was down $84 million, driven by unfavorable FX of $96 million, partially offset by growth in multiyear Software and Services contracts in North America.
Turning next to our outlook. We expect Q4 sales growth of approximately 4%, with non-GAAP EPS between $3.60 and $3.65 per share. This assumes a weighted average share count of approximately 171 million shares and an effective tax rate of approximately 24%. For the full year, we are again increasing both our revenue and earnings guidance. We now expect revenue in the range of $9.93 billion to $9.945 billion, up from our prior range of $9.875 billion to $9.9 billion, and we expect non-GAAP earnings per share between $11.65 and $11.70, up from our prior guide of $11.40 to $11.48 per share. This full year outlook assumes $40 million of FX headwinds, up $25 million from our prior guidance. A weighted average diluted share count of approximately 172 million shares and an effective tax rate of approximately 23%.
Before I turn the call back to Greg, I'd like to highlight two points. In addition to the strength of our LMR and Video business, our Command Center portfolio performed well during the quarter. In Q3, we achieved strong growth, complemented by a robust contribution from Rave, an acquisition, which continues to exceed our expectations.
Secondly, our supply chain execution navigating extended lead times for some semiconductors and reducing broker purchases continues to drive year-over-year cost savings. We now expect the impact of lower broker purchases to be a $70 million tailwind for this year, up from our prior estimate of $60 million. As a result, we now expect full year operating margin expansion of approximately 200 basis points, up from our prior guidance of 175 basis points.
I'll now turn the call back to, Greg.
