[Discuss-gnuradio] Too weak Tx power daughterboard problem

[Songsong Gee]

I have more than eight RFX 2400 daughterboards

and for a long time, I have left them unused.

Recently, I have tested TxRx test with those DBs

and only one transmits signal with a proper power level

but others cannot generate a such power level

In addition, some of them even cannot sense or receive signals.

(All test environment, options are same.

Actually, no options, means I used dafault value)

It seems around one month has passed since I left them unused.

Am I missing something? 

Say... kind of being assigned different options for not giving a specific option values?

or just a static electricity, or pine pollen problem?

What do you think of it.

Thank you for your advices in advance
