Thank you, Greg. Revenue for the quarter grew 13% and was above our guidance with record third quarter revenue in both segments. We also saw growth across all three technologies led by 33% growth in video security and access control. In LMR, which grew 9%, our supply chain execution during the quarter enabled us to ship additional product revenue.
FX headwinds during the quarter were $66 million, while acquisitions added $32 million. GAAP operating earnings were $373 million, inclusive of a $147 million non-cash fixed asset impairment charge recognized during the quarter related to the now planned exit from the ESN contract. GAAP operating margins were 15.7%.
Non-GAAP operating earnings were $676 million, up 22% from the year ago quarter and non-GAAP operating margin was 28.5%, up from 26.3%. This increase in operating margin was driven by higher sales, higher gross margins and improved operating leverage, particularly in the products and SI segment. GAAP earnings per share were $1.63 compared to $1.76 per share in the year ago quarter, primarily due to the impairment charge related to the expected early exit of the ESN contract. Non-GAAP EPS was $3 per share, up 28% from $2.35 last year.
This strong growth in EPS was driven by higher sales and margins as well as a lower effective tax rate related to higher benefits from stock comp recognized in the current year. Opex in Q3 was $521 million, up $25 million versus last year primarily due to acquisitions.
Turning to cash flow. Q3 operating cash flow was $388 million, up $12 million compared with the prior year, and free cash flow was $318 million, up $3 million. For the full year, we expect operating cash flow to be approximately $100 million lower than our prior guidance, primarily due to our continued investment in inventory, which is helping us execute in a dynamic supply chain environment and deliver against the continued record demand we're seeing in video security and LMR. Capital allocation for Q3 included $132 million in cash dividends, $94 million in share repurchases and $70 million of capex.
Additionally, during the quarter, we closed the acquisition of Barrett Communications, a specialty supplier of high frequency and tactical communications equipment for $18 million net of cash. Moving to segment results in the Products and SI segment, we continue to see strong demand across both LMR and video. Sales during the quarter were up 15% versus last year and orders were up 29%, including record Q3 orders for both LMR and video.
Currency headwinds were $28 million and revenue from acquisitions in the quarter contributed $13 million. Operating earnings were $375 million or 24.5% of sales, up from 20.6% in the prior year, driven primarily by higher sales and operating leverage, partially offset by higher material costs. The impact from our pricing actions increased in Q3 as expected, and we continue to expect full year operating margins in this segment to be higher than last year.
Some notable Q3 wins and achievements in the segment include an order in Israel valued at over $400 million for a duration of 25 years. This unique system integration project also includes over $30 million of fixed video equipment and software and is our single largest order ever for Avigilon.
$165 million P25 system and Apex APX NEXT devices award received from Miami-Dade County that includes a new customer for us in the state of Florida. A $67 million P25 order from Southeastern Pennsylvania transit authority, a $45 million P25 order from a customer in Africa, a $29 million P25 devices ordered from a U.S. federal customer, an $18 million TETRA order from a customer in Europe, and a $5 million fixed video order from a major transportation company in North Africa.
In service -- software and services, revenue was up 8%, which includes $38 million of FX headwinds and $19 million of revenue from acquisitions. Total software revenue was up 17%, driven by strong demand in video while in LMR services, revenue was up 4% after $33 million of FX headwinds.
Operating earnings in the segment were $301 million or 35.7% of sales, down 30 basis points from last year, driven by higher acquisition expenses. Some notable Q3 highlights in the segment include 2 large multiyear LMR service renewals, a $43 million one with the State of Maryland and $15 million with the City of Phoenix.
Also a $17 million push-to-talk over broadband order from a customer in the Middle East, a $7 million command center software renewal with Will County, Illinois, a $4 million body-worn camera order for the Texas Department of Public Safety, and a $4 million command center software suite order from Ellis County, Texas.
Looking at regional results. North America Q3 revenue was $1.7 billion, up 16% on growth in all three technologies. International Q3 revenue was $686 million, up 4% versus last year, with growth in all three technologies, partially offset by unfavorable FX.
Moving to our backlog. Ending backlog was a Q3 record of $13.5 billion, up 19% or $2.1 billion compared to last year, inclusive of approximately $826 million of unfavorable FX and a $99 million orders reduction related to the planned exit from the ESN contract. The growth was driven by the Airwave extension recorded in the fourth quarter of 2021 and increased demand across all three technologies.
Sequentially, backlog was up $87 million, driven by several large orders received during the quarter, partially offset by $411 million of unfavourable FX and the $99 million adjustment for ESN.
In the Products and SI segment, robust order demand in both LMR and video continues to drive record backlog, which was up $1.2 billion or 35% compared to last year. Sequentially, backlog was up $513 million which was our ninth consecutive quarter of sequential backlog growth in this segment.
In Software and Services backlog was up $876 million compared to last year, driven by the Airwave extension and a $288 million increase in multiyear services and software contracts in North America, partially offset by $722 million of unfavorable FX and the adjustment related to ESN. So sequentially, backlog was down $426 million or 5%, driven primarily by unfavorable FX, the ESN adjustment and revenue recognition for Airwave and ESN during the quarter.
Turning now to our outlook. We expect Q4 sales to be up approximately 9% and with non-GAAP earnings per share between $3.40 and $3.45 per share. This assumes $90 million of FX headwinds, a weighted average share count of approximately 172 million shares and an effective tax rate of approximately 23%.
For the full year, we are increasing both our revenue and EPS guidance again. We now expect revenue growth between 9.25% and 9.5%, up from our prior guidance of 8% and we expect non-GAAP earnings per share to be between $10.17 and $10.22 per share, up from our prior guidance of $10. 3 to $10. 13 per share. This updated guidance now includes full year FX headwinds of $220 million, up $50 million from our prior guidance, a weighted average share count of approximately 172 million shares and an effective tax rate of approximately 20.5%. This now also assumes $150 million of higher costs for the full year related to the procurement of semiconductors from secondary markets at a premium. This is a $30 million increase over what we indicated earlier in the year and supports the increased revenue included in our updated guidance today.
And finally, as I reflect on where we stand today with just 2 months left in another dynamic year, I'm encouraged with how our teams have been navigating the supply chain environment and overcoming the impact of a historically strong U.S. dollar.
At the beginning of the year, we expected currency headwinds to have a $60 million translation impact on our full year revenues. The full year FX headwind has increased by $160 million since then. The decisions we've made to carry higher inventory pay premiums for semiconductors and the pricing actions we implemented have enabled us to drive higher product revenues that not only offset these significant FX headwinds and but have materially increased our revenue and EPS expectations during the year.
I'll now turn the call back over to Greg.
