Member: 7751 Status: Offline Thanks Meter: 74 | @Rod Go to the section called Schematics/layout, and you will find those components, these components are mostly around CCONT, not too hard to find. Regards |

Member: 4758 Status: Offline Thanks Meter: 5 | yesterday with a 3410, the rssi without card was constantly at 112-113dB, but with card starts with full signal, then 3lines, 2lines, 1line, then no netw, after 10 seconds signal commes full again, but trying to call only single short burst Tx, i changed everything: ccont cobba hagar duplexer PFO the loop between PFO&duplexer, all electrolythic capacitors all filters in 900band, but the same. and finaly i solved the thing by changing RTC Quartz at ccont.... so that meens maybe was noisy. the rtc was correct meening the clock. bye, felix. |
