ANAN 8000DLE Fan failure & Low sensitivity
Posted: Sun Feb 23, 2020 7:45 pm
Hello,
Yesterday night I was operating FT8 and I probably heard some noise in the radio and then it was completely calm and realized fan stopped working and as temperature was rising above 40 and I switched off the radio and after 30 minutes when I switched on and connected with thetis, Seen that noise floor was much below and S meter reading was around S2/s3 usually its around S8/9 on 20 and above S9+10 or so on 40/80.
Frustrated, I switched off and went to sleep. Today morning radio was behaving normally and noise floor was up and fan wasn't working. when temperature reached around 45 I switched off and after some time i was at the operating table to find radio deaf again. This time when temperature was around 42 noise floor dropped and S meter was again S3.
Why fan Failed and why sensitivity is failing? Is it some relay issue? What to look for? What are the safe temperature levels to operate? I believe around 60.
Please help?
