Project Startup Help
Thought for 5 mins 28 sec
They’re still running. I’ll check final status once more and then give you the project links and current state so you’re not blocked waiting.
Worked for 21 sec
Created two separate PCB projects and started the split/place work in each:
- TX board: /timbochu/munkrofon-tx-pcb
- RX board: /timbochu/munkrofon-rx-pcb
Current status:
- TX clone: RX circuitry removed, board-mounted XLR replaced with compact XLR harness pads, 25 × 80 mm / 4-layer target set, placement still running.
- RX clone: TX circuitry removed, board-mounted XLR replaced with compact XLR harness pads, 25 mm width / 4-layer target set, placement still running.
- Master project remains unchanged as the system/reference design.
Open item:
- Both split-placement tasks are still running; they exceeded the wait window but are actively working on non-RF placement and verification.
Next step:
- Open each project link later to review the completed thread result, or ask me to check their status again.
Check split projects
Check TX status
Check RX status

Product Description
Munkrofon is a compact rechargeable professional wireless microphone transmitter/receiver PCB set. The prototype uses a passive dynamic microphone connected by XLR, transmits low-latency digital audio over a DECT-class RF link, and outputs true balanced audio through an XLR receiver output.
Wireless Technology Summary
Table
| Module | MPN | Technology | Frequency Band | TX Power | Pre-certified? |
|---|---|---|---|---|---|
| RTX1090R1 | RTX1090R1 | DECT / DECT 6.0 / J-DECT-capable module | 1880–1900 MHz EU, 1920–1930 MHz US/Canada, 1893.5–1906.1 MHz Japan per RTX public product sheet | Software-configured; public datasheet cites regulatory EIRP limits | RTX1090R1 public materials cite FCC/MIC modular approval, but final integration conditions must be obtained from RTX |
RF Design Notes
- RF module footprint and antenna circuit are provisional.
- Antenna placeholder components AE1–AE4 are not production antenna layouts.
- Final PCB must follow RTX/RMED reference layout or approved antenna/matching network.
- RTX public datasheet notes antenna design must be separated from electronics, placed in a non-shielded environment, and impedance matched in the representative enclosure.
- RTX1090R1 public materials reference PCB antenna usage as on RTX1x90EVK, max gain 6 dBi, 28 mm × 6.5 mm dimensions for modular approval conditions; exact EVK files are still required.
Required Documentation Checklist
- Draft schematic exists in Flux for Prototype Revision A.
- Draft BOM exists from current schematic.
- RF module public datasheet/product-sheet links recorded in RF Module Selection notes.
- Official RTX hardware integration guide.
- Official RTX/RMED reference schematic/layout/Gerber/stackup/BOM.
- Official antenna integration and modular-approval guide.
- RF test mode commands and production test procedure.
- Final PCB layout / Gerbers.
- Accredited EMC/RF test reports.
- Final Declaration of Conformity.
- User manual with wireless/regulatory labeling notes.
Open Regulatory Risks
- Modular approval may not apply if antenna geometry, gain, placement, matching, ground clearance, enclosure material, or firmware TX power differs from the approved RTX reference.
- The provisional antenna placeholders are not sufficient for compliance.
- Final regional band configuration must be firmware-controlled and locked for each market.
- Battery charging safety and USB-C labeling must be reviewed before shipment.
