Product Introduction
Sperry Marine T65801801-13 is a marine radar trigger PCB used in X-band and S-band radar systems. It controls scanner timing inside Sperry Marine BridgeMaster-type radar hardware and is sold as a replacement board for service and maintenance work.
Buyers usually choose this part when the radar scanner loses trigger timing, stops rotating correctly, or shows comms and timing faults tied to the transceiver chain. Match the exact revision before install; radar board swaps are where people lose time on compatibility.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Radar scan is dead, but display powers up | Trigger PCB fault, power issue, or transceiver problem | ✅ High | Measure supply voltage at the board, then check trigger output with scope if available | Replace only after confirming input power and interlocks |
| Antenna does not rotate in sync | Trigger timing failure or motor drive issue | ✅ High | Inspect trigger pulses and compare against the service manual timing chart | Confirm board revision before replacement |
| Intermittent radar returns | Loose connector, bad timing signal, or scanner-side fault | ✅ Medium | Reseat connectors, inspect pins, and check for bent terminals | Replace only if wiring and connectors test good |
| Radar works on one band but not the other | Band-specific configuration or mismatched board revision | ✅ High | Verify radar type, band settings, and part number against the unit label | Do not swap blindly between X-band and S-band builds |
| No fault at board, but radar still fails | Display unit, PSU, magnetron, or rotary joint issue | ❌ Low | Check system diagnostics, power rails, and related subassemblies first | This part may not be the root cause |
| Unit boots, then drops radar output | Thermal or intermittent board failure | ✅ Medium | Run the unit under load and watch for signal loss after warm-up | Replace if failure repeats with stable input power |
If you get stuck, contact technical support with photos, radar model data, and any diagnostic logs before ordering a replacement.
Frequently Asked Questions (FAQ)
Q: Is T65801801-13 an exact replacement for my Sperry Marine radar?
A: It can be, but only if your radar model and board revision match. Marine radar boards are not forgiving when the part number is close but not identical.
Q: Can I use this for both X-band and S-band systems?
A: The part is listed for X-band and S-band compatibility, but you still need to confirm the exact radar build and installation variant before buying. On marine gear, band compatibility does not always mean universal fit.
Q: Is this board new or refurbished?
A: Stock for this type of part is often new surplus or tested working, not factory fresh. That is usually why the price is lower than OEM direct supply.
Q: Will my radar settings or programming be lost when I swap it?
A: Usually the board itself does not hold your full system configuration, but you should back up the radar setup before any hardware change. I have seen simple swaps turn into long nights because nobody saved the original parameters.
Q: Can I hot-swap it?
A: No, do not assume hot-swap. Kill power first and follow the radar shutdown procedure, or you risk damaging the board or the backplane.
Q: Why is it cheaper than buying from the factory?
A: Because it is typically surplus, not a fresh OEM production run. The tradeoff is availability and price, but you should still verify condition, test status, and revision match.
Q: What should I check before installing it?
A: Match the part number, inspect the connectors, confirm the radar model, and compare the old board’s labels and switch settings before removal. That one photo from teardown saves a lot of rework.
