Hello,

I am having problems with my 900 Mhz Quantar transmitting. I get the following messages:

2010/12/20.15:43:50 2010/12/20.15:45:33 6 SC SYSTEM_STATUS 3426 HC11 EXT_CIRC_TEMP_ALARM

2010/12/20.15:43:50 2010/12/20.15:45:33 6 SC SYSTEM_STATUS 3239 HC11 INT_WM_FWD_PWR_ALARM

2010/12/20.15:43:51 2010/12/20.15:45:20 5 SC SYSTEM_STATUS 3384 HC11 NO_FORWARD_PWR

2010/12/20.15:45:26 2010/12/20.15:45:26 1 SC ROUTE_SERIAL_DATA 563 BAD_OPCODE 292

2010/12/20.15:45:34 2010/12/20.15:45:34 3 SC ROUTE_SERIAL_DATA 563 BAD_OPCODE 293

I don't understand the first message because there is no external circulator. It comes up as soon as TX is keyed even if the system hasn't been on for hours. The ambient temperature in the rack is 72 degrees F.

The last two messages seem to be some kind of communications error between the PA and the station control.

Any help is appreciated.

Does your codeplug have a peripheral tray enabled, but not actually have one?
Or is a Quantar with a Quantro codeplug?
Could also be a PA issue.

I checked for that but this is not a new install and the problem came up after having had a high SWR on the antenna. There was water in the connector so we fixed that and re sealed the connection. Ran fine for several days afterward.

Sounds like the rfpa died. I would check the station keyed into a dummy load to see how it behaves.

There is a circulator IN the PA assembly. That is where you are getting the high temp alarm from.

The PWR alarms are indicators of no output at the sensor when the unit is keyed.

Not sure on the OP Code alarms but the final answer is the PA is certainly bad.

I will also assume that when you key the station you don't get a PA Full light on the front of the PA either.
